Thursday we unboxed our highly anticipated TAZ4 #3DPrinter, which we won as part of the #LulzBot 4th Annual Hackerspace Giveaway.

It rulez !!

We have a very coloured history when it comes to 3D printing. Ever since we ordered the first parts for our self-built RepRap Mendel years ago, 3D printing was something you did not mention easily at realraum.

The RepRap was built, rebuilt, adjusted, taken apart, modified and hacked, again and again. All with mixed success. While we did learn a lot about 3D printers in the process, likely spent more than 300 man hours on it and even wrote a big TeaCup firmware patch, the thing probably only ever spent a sum total of 2 weeks out of 5 years in a state where it could actually print, badly! Most of the time however, nobody knew who last took apart what or was planning to improve which thing next.

Then came the MakiBox. Co-sponsored by one of our founding members (who resided in Hong-Kong at the time and co-founded DimSumLabs there) Always on a tight budget, this first-of-the-line production model seemed the perfect way to finally make 3D printing a reality here at realraum. Especially since said founding member was sponsoring it. In its defence can be said, that, frail as the design was, it did actually print in the beginning. Unfortunately that state would not hold very long. We then decided not to review the MakiBox, as we were missing the words to describe just how crappy it really was.

Again, 3D printing was not mentioned at realraum for about a year.

Finally, along comes the Lulzbot TAZ4.

After just a few days it may be a bit much to say â€œLulzbot rescued 3D printing for usâ€Â, but that's about what it feels like right now.

It has a large print area and is capable of very fine and precise prints. It follows all best-practices I've ever read about making 3D printers. E.g. it has a heated glass-surface which is perfect for PLA. Beyond that, you might even accuse Lulzbot of over-engineering. Looking at the industrial grade cable connectors, screws, bearings and shaft couplings, you know they didn't skimp on the parts. Next to that is ships with a bag of quality tools which even includes a jar for mixing ABS and Acetone.

[caption id="" align="alignright" width="414"] comes with ALL the tools[/caption]

Our first test prints came out very well. Even when stress-testing with our crappy old PLA roll, the prints came out very nice. The nice fan and air-guide works just as expected and overhangs printed without problems. Using rafts, even delicate and complex prints with little surface area came out fine.

To show off the printing process (and experiment with gstreamer), we mounted a webcam on the platform, the resulting time-lapse videos can be found in the gallery.

It does have its hard edges, but this printer is not meant to be super-user-friendly and DAU-resistant. Instead it is hackable, open-source and a precise straight-forward work-horse. Just how we like it! Despite our hack-at-it attitude, we _did_ appreciated the big and surprisingly useful user-manual as well as the handy illustrated first-steps flyer.

[caption id="" align="alignright" width="412"] and ALL the instructions ;-)[/caption]

All in all, the printer gives manages be at once a highly professional machine as well as a matured hackable open source project.

Of course, it would not be bitchy us, if we didn't find anything that could be improved. Most of that can be traced to the firmware: The sampling of the rotary encoder for once feels sluggish and imprecise even though the encoder itself is high-quality. We also wonder if the forces reset on sd-card change and usb-cable plugin is really necessary. Finally, it's OK that the printer does not print from SDcard when still connected by USB, but it could display a warning instead of just plainly doing nothing after one selects â€œstartâ€Â. Also the resonance frequencies of the printer could have been measured and the firmware modified so it would then avoid certain of those speeds and direction changes. Since it's all just software, we may actually do something about that in the future On the hardware side, we noticed that the power supply's cooling fan would still run long (hours) after the printer had been switched off. (Note: the only big off switch is on the DC voltage side of the printer). Not sure if that fan actually ever stops.

All that (and on the bitchy side: the fact that it's just that) really really shows just how much experience and know-how (hard won over the years of DIY 3D printing I'm sure) went into making the TAZ 3D Printer. Thanks #LuzlBot !!

Heute fand im realraum ein gut besuchter Lasercutter Workshop statt. Etwa 20 Interessierte lauschten der EinfÃ¼hrung in die Lasercutter-Software und der praktischen EinfÃ¼hrung am GerÃ¤t. Im Anschluss konnten auch gleich einige Projekte realisiert werden.

Mehr Infos zu unserem Laser so wie laufende Projekte findet ihr in unserem Wiki. Ebenso im Wiki findet ihr Materialparameter fÃ¼r den Laser.

+We all hope to see it fill up in the coming days!

Der realraum war auf der diesjÃ¤hrigenÂ BeStÂ³ vertreten. Die Messe fÃ¼r Beruf, Studium und Weiterbildung fand vom 15. bis 17. Oktober in der Grazer Messe statt. Wir konnten einige Projekte aus dem realraum prÃ¤sentieren und das junge Publikum fÃ¼r die Technik begeistern. Besonders der Audiance Rection Indicator, intern auch Applausometer genannt, erfreute sich groÃŸer Beliebtheit.

Danke an alle Beteiligten, insbesondere Selene, Sasa und xro.

Where do you keep all the cables in your lab? Maybe you zip-tied an old rake to the wall and repurchased it to hold your twisty coils? Thinks it may be time for a cleaner solution? Wood, Drill, 3D-Printer and half an hour of time, to the rescue.

One of the oldest tricks in the book: drill a few holes into which to stick your lab-cables. Screw in a few screw to clip your clips on. Use a bit of pliable wire to create holders for your test prods, and voilÃ : a tiny bit less chaos :-)

Our trusty TAZ4 even takes us a bit further, spitting out a nice custom made BNC-cable holder.

Next Tuesday (24th), I will hold an OpenPGP workshop in rÂ³, starting at 20:00.

OpenPGP is a (some say the) standard for providing strong cryptographic confidentiality and authenticity for files, messages, software, ...

If you use an operating system that authenticates its software updates (and that is not Windows), you probably already rely on it without knowing!

You can find all the details in Grical, but here is a quick overview:

We will talk about what this is, and what this is not.
We will walk together through how to use this.
We will discuss best practices, and how to apply them in a not-inconvenient way.
Bring your own laptop, and a USB thumbdrive that you can format (even better, install Tails on it if you know how).

Some of you might know this little signs saying "Made with â™¥ in San Francisco" (or similar) on the webpages and gadgets you love. We also make stuff with â™¥, not all of it digital, so we made our own sign. :-)

If you feel like it, you can use our sign - our make your own. You can find the used file in our logo git Repository on GitHub. (By the way, we use the Cagliostro font for our logo.)

Although not a big fan of Christmas, tradition, and Christmas tradition, Stefan used the realraum nightshift to build a lamp as a Wichtel present. The lamp features a mountain on the front side, which is lit from the inside by some simple LED setup. Furthermore, it is able to change the color of the light via an IR remote.

The process of creating the lamp involved vectorizing the image, lasercutting the pieces, rasping some small errors, soldering and glueing of all the things! So basically all important parts of realraum's infrastructure were used in building the lamp. ;-)

Special thanks to erdbrbl, equinox and xro for their assistance, guidance, and teaching me how 2-components adhesive works.

2016...der Start in ein neues Jahr. Auch heuer sind wir top-motiviert um neue Projekte in und rund ums Labor ins Leben zu rufen. Das OLGA bietet jungen ForscherInnen und WissenschafterInnen die MÃ¶glichkeit sich selbst zu verwirklichen, ihren Wissensdrang nach zu gehen und den Durst nach alternativen Formen der Wissenschaft, wie sie stets als Praxis bezogene Handlung vorliegt, lÃ¶schen kÃ¶nnen. Â Denn jede Theorie ist nichts wert ohne ihre Praxis.

"Self-made" wird bei uns groÃŸ geschrieben. Damit ist nicht nur das selbststÃ¤ndige Arbeiten sondern auch die Projektplanung, die Einrichtung, Werkzeug, Proben & Materialienbeschaffung...ganz im Namen der Maker-Scene.

SelbstverstÃ¤ndlich bauen wir keine Photometer oder Zentrifugen selber, aber wir kÃ¼mmern uns persÃ¶nlich darum im Kontakt mit Instituten zu stehen, die teure GerÃ¤te aus GrÃ¼nden kleinster MÃ¤ngel entsorgen mÃ¼ssen, und holen uns diese direkt ab, schaffen sie in unser Labor und bÃ¼geln die MÃ¤ngel wieder aus um dann ein tolles Mess- oder ArbeitsgerÃ¤t zu besitzen.

Erst beim Entstehungsprozess denkt man darÃ¼ber nach, wie man vom derzeitigen Zustand und vorhandenen Mitteln zum eigentlichen Ziel kommt. Und auch ohne groÃŸen finanziellen Mitteln kann man viel dazu beitragen, man muss nur ein bisschen grÃ¼beln und Ã¼berlegen.

Was das Ziel ist, dass steht gar nicht so deutlich im Vordergrund. Die Erkenntnis wÃ¤hrend bestimmter Arbeitsschritte bringt einem persÃ¶nlich viel mehr, denn Erfahrungen kann man spÃ¤ter immer brauchen, oder man hat einfach SpaÃŸ an der Wissenschaft, so wie ich ;) Â SelbstverstÃ¤ndlich aber versucht man auch etwas zu kreieren, seine Arbeit FrÃ¼chte tragen zu lassen. Als Biohacker und non-profit Verein mÃ¶chten wir die Erfahrungen und Resultate der Experimente mit Anderen teilen und versuchen so einen Schritt in die Richtung der freien und unabhÃ¤ngigen Forschung ganz im Sinne des Open-Access zu betreiben (man mÃ¶ge anmerken, dass das Verfassen von schriftlichen Arbeiten fÃ¼r sÃ¤mtliche ForscherInnen nicht immer ein VergnÃ¼gen bereitet, weshalb die Motivation dafÃ¼r bislang relativ klein, aber dennoch vorhanden ist ;) Â Als aktiv forschendes Mitglied mÃ¶chte ich daher um etwas Nachsicht bitten, denn die meisten von uns sind noch hauptsÃ¤chlich StudentInnen, ArbeiterInnen oder zu sozial um dauernd vor dem Bildschirm zu sitzen und zu schreiben :) Â Aber wir geben uns MÃ¼he).

See ya,
+D3

licht.realraum.at, went FTLw today. That is... it became much Faster Than Last week. :-)

Since the Raspbian image upgrade and move to a bigger (but slower) SDcard, licht.realraum.at had become truly sluggish. To the point that pressing a button to turn on the light or change the stereo volume could take up to 6 seconds until something happened. (Obviously we disabled the swap-file long ago.)

The problem was quickly identified. Processes don't load quickly enough.
+The fact that the whole systems was a dunghill of bashscript cgi-scripts and python helper scripts also did not help. At all.

First attempt to rectify this: rewrite the python helper rf433ctl.py. Formerly it was a simple script that would be called by the cgi-script and send the appropriate bytes down to the teensy.
+Each call to it, however now took forever. So. I rewrote it as a daemon that would constantly stay in memory and be nudged by other instances of it via RPC. The idea being, if it's already completely in memory, loading a second instance should be faster. Right? Wrong!. Unfortunately that did not work out at all.

Second attempt to rectify this: Remove the kiosk functionality and thus memory-hog midori from licht. Thankfully a very nice person gifted us a RaspberryPi per (almost) anonymous letter, so we had the necessary hardware on-hand to split the functionality onto two separate boxes: licht.realraum.at and smallkiosk.realraum.at
+Unfortunately, even freeing up 60% of memory did not even put a dent into the problem.

So.. third and last attempt. Hit it with go ;-> In a 3 hour session, I rewrote the whole dunghill as a monolithic golang daemon/webserver/tty-handler which, once loaded, always stays in memory. Then I got rid of lighthttpd and the python scripts. Result... Speedup from 6s to <=0.05s !!

Should have done this right away really...

This months membership meetup was more cozy than usual. Also a lot more productive, judging on what happened the days after ;-)

The highlights:

Easterhegg 2016. Originally we wanted to help out with cool lighting and take part as a big realraum delegation from Graz. Unfortunately tickets were quite suddenly and unexpectadly sold out. So there will be no realraum @ Easterhegg 2016 Salzburg. Too bad. Very sad. Some of us are going to Revision16 instead though.
Lasercutter exhaustvent and OLGA vents. Is finally going to be built. See upcoming post with pictures.
Curtain: Will finally happen. New curtain rod installation was finished on Wednsday and Curtain is scheduled for hanging on Friday.
mur.at: The future of our internet uplink is in flux. Interessting stuff will happen 2016/2017.
Finances: Over the next months we will test and then maybe introduce a new formal system for financing stuff in realraum.

On February 1 there was once again the monthly Python Usergroup Graz meeting.
+This time it didnâ€™t take place at the Spektral, though, as at the
+last second (well, a week in advanceâ€¦) a schedule collision happened and the
+nice folks behind spektral had to use that room for themselves. Luckily,
+within a couple of hours a new venue for that evening was found at the
+Realraum! Big thanks to Michael and everyone else who helped here!

So, what happened? We had two talks! Horst gave a short tour through some of
+nice string-formatting mechanisms you have with Python, something he had already
+written about here a couple of weeks ago. If you want to learn more, simply
+read that post and visit pyformat.info, which contains many more examples ðŸ˜‰

Right after that, we had a quick introduction into some of the awesome things
+you can do with Pandas. Big thanks to Moritz for that ðŸ˜Š You can find his
+slides on our mailinglist.

We also had three visitors from the Vienna Python usergroup who come by
+every once in a while and who have their next meetup incl. a coding dojo
+on February 17 at the Metalab ðŸ˜Š

The next meetup in Graz will be on March 1 most likely again at the
+Spektral. Official announcement will be made soonish on Meetup.com,
+our website and all the other nice places you can find us ðŸ˜ƒ

Since the foundation of realraum, we love to tinker with automating the room and playing around with sensor data. Yesterday we had a small talk where I could give an overview of how all that stuff currently works and what technologies we play around with.

Have a look at the Wiki Documentation with a description of how MQTT is used or the Slides.

Buntes Treiben und nein, es ist nicht Faschingsdienstag im OLGA.

Nicht nur, dass wieder viele Leute uns die Ehre erteilt haben uns am Anfang des Semesters zu besuchen und sich das Open bioLab Graz Austria anzusehen, auch wenn aufgrund von Umbau-Arbeiten wenig Platz vorhanden war.

FÃ¼r diesem Zweck haben wir Serratia und Pseudomonas- Kulturen aus dem KÃ¼hlschrank geholt und damit LB Medium beimpft, die ONC haben sich nice verfÃ¤rbt.

Aus den Kulturen wurden dann Glycerol-Stocks hergestellt und bei -20Â°C gelagert, fÃ¼r Arbeiten im kommenden Semester. Die anderen StÃ¤mme vom OLGA werden dem selben Vorgang unterzogen.

Was fÃ¼r wissenschaftliche Arbeiten stets voraus gestellt wird und dem nichts-ahnendem Forscher immer ein Ã„rgernis erspart sind Kontrollen. Hier sind vier unterschiedliche Kulturen auf MacConkey-Agar ausgestrichen worden:

Bis auf eine sind sÃ¤mtliche Kulturen in Ordnung, nur E. coli XL1 muss erneut begutachtet werden bevor die Glyc-Stocks erstellt werden. Die Platten, von denen Bakterien zum Inokulieren entnommen wurden, sind immerhin den ganzen Februar ungeachtet im KÃ¼hlschrank gelegen.

Once again, one month's member's meeting is adjourned and a lot of things are now to do. :)

Lots of things happened.

Today we got the last necessary parts for our pneumatic tube system aka lasercutter/OLGA ventilation system, for one. There's a good chance that after one year it will finally be completed this month. For another, the curtain got done. We decided to improve on the rings (currently zip-ties) that hold it, finally found matching rings and ordered them.

NOC reports that project "one-member-account-for-everything" has come closer to completion. Instead of suffering problem riddled and partially insecure LDAP and outdated Kerberos we started to develop our own GSSAPI-compatible authentification replacement project. Take a look.

Status on our ticket-system is not so good. We tested two but they are suboptimal and we remain unconvinced. Still, we need one.

Upcoming Events:

This Friday, there will be RetroGaming. NES, C64, GameCube, Amiga 500, SegaMaster, SuperNintendo, lots of fun! :-)

Starting next month, the Internet-of-Thinks / Homeautomation Meetup will become a regular thing. Every third Thursday of the month.

Somewhen after the Easter Holidays, there may be a Minix3 on BeagleBoneBlack install party.

GLT16 is coming up and we'll have a booth and are considering organising some post-Linuxtage party or event.

Camp++ in Hungary in August now has a fixed entry on our schedule. Hopefully lots of Austrian Hackerspaces will take part.

Mary Ward from Counter Culture Labs in Oakland, California is currently visiting Graz. Today she gave a talk @ realraum about her idea of doing microfluidic mRNA assay in space. Those were some really great ideas and nice example of putting existing stuff together to make even more exciting stuff.

Since we already have a lot of experience with microfluidics and building space-worthy satellites, this turned out to be the perfect topic for our space. Beautiful discussion and knowledge exchange ensued and will continue on Sunday. :-)

Around the end of Februar 2016 prints with our trusty only 11 months old TAZ4 3D Printer started to fail. Specifically the extruder just stopped extruding mid-print, while everything else was working along as if nothing had happened.

After some investigation, we discovered the problem, the extruder stepper motor was getting waaayyy tooo hot. Each time, about 10 to 15 minutes into a print, the extruder/feed stepper would reach 91Â°C and just stop moving. As no more filament was being extruded, prints were getting ruined.

Fixing It - First Attempts
+

First I ran a print with the filament removed, the filament tension mount relaxed in order to reduce any resistance the stepper might encounter. Still it overheated. Obviously we tried attaching a heatsink, but of course that just bought a few extra minutes.

My first idea was to trim the micropotis on the controller board and reduce the motorcurrent. Alas, there were no potis to be found. Then equinox suggested it might be a mechanical problem since everything was working fine the last eleven months.

So we took the extruder apart twice. Second time around an hour later, we discovered that the M10 nut of the bolt conveying the filament which has the big cog on it's other side, was way too tight. Presumably someone wanted to improve things by tightening the screw.
+The result being, that the washer pressed on the bearing and put the brakes on the extruder motor.

Additionally I discovered that the screw afixing the steppershaft to the PLA cogwheel was loose. Possibly the hot motor softened the PLA enough for the shaft to slip through and cause the motor to turn by itself.

Sadly, none of these fixed solved our problem. Our NEMA17 still overheated, with 90Â°C being far outside it's absolute maximum rating of 60Â°C (Specs) and even further away from the 42Â°C operating temperature reported on the internet.

Fixing It - Delving into the firmware.

[caption id="attachment_580" align="alignright" width="300"] Heating resistor, dead and crumbling apart[/caption]

Returning to my first idea, I found out that the Rambo1.3L controller board used by the TAZ4 does allow one to adjust the motor currents. It actually uses a digital potentiometer, an SPI connected AD5206 chip, to adjust the current limiting reference voltage for the stepper drivers. Cool stuff, the firmware can actually adjust the stepper current. Allowing the user to either change values with GCODE commands M907 and M908 or by changing DIGIPOT_MOTOR_CURRENT #define in Configuration_adv.h and recompiling.

I thoroughly tested various settings but to my surprise, there did not seem to be any noticeable effect. In fact, even setting the current to zero, did not affect any of the steppers at all.

The TAZ4 Marlin Firmware comes with it's own SPI Arduino library, so I tried that as well as the newest version. No difference.

Somewhere at this point, bug hunting went on so late into the night that I even started hallucinating bugs in the Marlin Firmware that weren't really there.

Fixing Other Stuff.

[caption id="attachment_567" align="alignright" width="300"] brown spots on the middle left were stepper drivers are on the backside[/caption]

During testing we also discovered, that the extruder would not heat up. A problem we quickly traced to the heating resistor which basically crumbled in my hand when I inspected it. This was probably a result of our printing experiments with Bridge Nylon at 335Â°C and quickly fixed as Lulzbot thankfully uses a common resistor that can easily be ordered online.

Fixing It - Delving into the hardware.

The next step was looking up the AD5206 datasheet and RAMBO Schematics, dusting off my OpenLogicBench analyser and sniff that SPI bus. This was not without problems, as the SPI signal was barely recognizable on an oscilloscope as long as the display was connected to the SPI bus as well. The logic analyser could not even differentiate HIGH from LOW. After disconnecting it, we had much more luck decoding signals on the oscilloscope but not with the logic analyser.

[caption id="attachment_581" align="alignright" width="300"] SMD Hot-Air-Soldering Rambo1.3L on RepRap Heatbed[/caption]

After many hours of experimenting, I finally concluded that the AD5206 was shot. No matter what command was sent, the reference voltages generated would remain the same. The Z and E axis was always driven with the maximum current. On the Z axis, that was ok, since the current is split between two motors. For the E axis, it was the cause of our overheating problem.

Inspecting the backside of the board, one can even clearly see where the high current going through the E0 and Z stepper drivers blackened the backside of the board. (two chip-sized dark spots)

Seeing it as a nice opportunity to test some SMD soldering skills before replacing the whole board, I ordered some AD5206 chips.

[caption id="attachment_582" align="alignright" width="300"] Later version of the PID controlled heat-bed being tested with some Sencha green tea[/caption]

On of our members, Laszlo, lent realraum his Hot Air Solderer. In order to make things go even smoother, I re-purposed our old RepRap heat-bed as a Teensy and PID controlled, SMD preheating plattform. (With OLED Graph and WS2812b LEDS of course)

As our USB microscope revealed, my soldering work turned out to not be picture perfect, mostly due to difficulties cleaning the pads of excess solder. All pins had good connection however and thus I moved on to testing.

Unfortunately it turned out, that, while the AD5206 clearly reacts to SPI commands now and the reference voltages could be changed with GCODE commands, I could only affect change in a range of 0 to 9mV for E0 and E1 rather than the full necessary range of 0 to 1.8V. Funny enough, the values for the X,Y,Z axes were still approximately correct, but similarly could only be affected in a range of 9mV. Obviously something else was broken or broken as well.

At this point, I might have tried fixing the reference voltage with fly-wire voltage dividers. Instead I decided to not sink any more nights into the project but just order a new Rambo board. Especially as the backside clearly showed where the board suffered too much current and heat and more things might be broken.

[caption id="attachment_568" align="alignright" width="300"] New board finally arrived[/caption]

Fixing It - Ordering a replacement Rambo1.3L

Comparing prices including customs tax, we ordered from the UltiMachine online shop. The board was promptly shipped and arrived in Austria only a few days later. Not grounds for immediate joy however, as Austrian customs is currently understaffed and decided to not even look at our parcel for four !!! whole weeks. I wonder if most of the customs officers were sent on holiday during the Obama EU visit, in order to make some roundabout statement about how, if only people would stop their valid fear of american food products and accept TTIP into their bodies and hearts, their parcels would arrive much faster. (No I obviously don't really believe that, but it's a fun idea)

[caption id="attachment_598" align="alignright" width="300"] Successfull print with new board and settings[/caption]

Yesterday, the board finally arrived and got installed.

Today, after some tests I was very pleased with the E0 stepper temperature staying at a comfortable 45Â°C now. However X and Y steppers were getting slightly hotter than before. (60Â°C after 1h of printing.) Of course we don't want to lower the values too much as it would impact acceleration. After some fiddling, I went with what should be 0.275A less current for those steppers and set the values below in Configuration_adv.h.

After a bit of testing I'm not entirely convinced that all the settings reach the AD5206 correctly each and every time. Might be the display connected via long wires in a star configuration of the same SPI bus is a design issue. Likely a bit more testing is still required.

Still, after 1.5 months we're finally able to 3D print again. Celebrations and careful printing may commence :-)

Our shelf next to our electronics corner, aptly named TESLA, is getting a bit crowded. Luckily we have our own lasercutter. Why not make drawers? After today's lasercutter workshop, nothing would be more obvious. So I made the beginning and created the first. The basic idea now is:

If everybody who doesn't know where to put stuff any more, makes just one drawer, we will end up with a cool and individualized shelf.

Everybody is invited to use the drawers in this github repository to get started quickly and add their own designs.

In other News: H sponsored earphones, so people watching videos on WÃ¼rfel, our pc directly connected to the room's stereo, no longer need to play to an audience.

+There definitely were some before,Â using third-party packages (including my other laptop), by this is an important step for nativeÂ ZFS support in Debian.

I will probably be involved, in the coming weeks, in squashing ZFS bugs and making sure thatÂ Debian Stretch users get a smooth ZFS experience.
+Don't hesitate to drop by and ask questions if you are curious about ZFS, or borrow the ZFS books I added to the library Â ;-)

The whole install is described hereÂ and onÂ a post to the pkg-zfsonlinux-devel mailing-list.

Not long after realraum moved to it's current premises, we knew we wanted a curtain in the front windows, just like in the old realraum. Not only to better use the beamer during the day, but also to keep the room cooler in the summer and have a tiny bit more insulation in the winter. There was also hope of it dampening echos and loud noises.

That was about 2 years ago.

[caption id="attachment_668" align="alignright" width="300"] finally some sturdy wood[/caption]

But how to hang the curtain. The ceiling after all, does not bear any loads. The search for a solution that would allow us to move the curtain freely over the ranges of a 4 and 5 meter wide front window began. The old curtains were both too short and not enough. Where to get nice looking fabric cheap, that is both fire retardant and thick enough to insulate was also an open question. Of course such fabric would be heavy and did I mention the ceiling does not bear any loads.

Now enter a handful of engineers with dwindling spare time, different opinions and varying expertise into the mix and you may begin to see what took so long.

[caption id="attachment_669" align="alignright" width="300"] one of two long pipes[/caption]

Quite early, we agreed that spanning two extremely sturdy pipes from one wall to the column to the other wall was the solution to go with. Eventually Christoph procured one for us which was a bit thicker than anticipated. Somewhen, frequent visitor and hobby seamstress Sasa managed to get us between 200 and 300 mÂ² of great fabric for a bit over a 100 Euros. Thank you Sasa for making them into curtains and even putting in the eyelets.

Some very motivated members promised to mount the pipe but went to work more quickly than anyone had anticipated. Miscommunication happened, some mistakes were made. Finally we re-mounted the pipe three times.

[caption id="attachment_672" align="alignright" width="300"] zip-ties a smooth sliding curtain not makes[/caption]

The first attempt had to go because the wood holding up the load was too thin. Instead of the planned U-cut to hold the pipe, an easy V-cut was made. The pressure exuded on the panel in direction of the fibres caused the wood to crack pretty early on. Then, instead of moving away the cable conduit (which later, turned out to be really easy to do), a daring constructions of wooden distance holders bridge was built in order to mount the pipe-holing-wood on topÂ of the cable conduit. While not very tidy, the real problem here was that the screws were too long for the holes drilled. (Understand: were talking about a massive and solid concrete column holding up the whole house. Even with the right equipment that doesn't drill easily).Â Consequently there was an air-gap between the column and the wood holding up the pipe. As we all remembered that day: screws hold stuff in place by way of static friction, i.e. pressing one material onto another e.g.. by pressing a piece of wood against a wall. They are not meant to withstand orthogonal forces and do not like to bear loads that way. Christian was the first to spot the air-gap. Exasperation and learning followed

[caption id="attachment_671" align="alignright" width="241"] should bear a few hundred kg[/caption]

Eventually, the sturdy, thicker than what your normal hardwarestore sells, wood we wanted to use in the first place appeared and the pipe-holders got completely redone. Sturdy enough to hang a small car on it. Or, you know.. a curtain and some people that might stumble into it during a party. Gotta plan for everything.

Finally, the pipe was not sufficiently secured against longitudinal movement. Meaning the direction in which you would pull when you move the curtain. Too much and the strings holding it in place might rip and crash everything down. Thankfully Christian also finally drilled holes at the ends and secured them with bolts across and through the pipe.

Don't exhale yet, we're not done.Â The curtain still had to be mounted, and guess what. Curtainrings that fit a 42mm diameter pipe are really really hard to get. We tried to make due (thanks to Sandra for all the work), it's really hard to move a curtain that is hanging on 150 tightly bound zip ties. Eventually we found a German shop that sells big metal rings at a surprisingly reasonable price and ordered right away. I don't even want to explain why it then took 3 months for them to arrive.

Yesterday, then, the long road had an end, the project finally got done. Our junior member David took up heart and down the pipes, replacing the zip-ties around the pipe with well moving (and sounding) metal rings.

[caption id="attachment_673" align="alignright" width="300"] no more shifting rods[/caption]

So end of story. Finally. Or is it? Because we also ordered clips to hang the curtain from it's eyelets to the rings. We ordered new eyelets with a bigger inner diameter because the clips would not fit in the very small ones we had when Sasa and Sandra put them in. (Never believe the online-shopping product description). Right now the curtain and the clips/rings are still connected with zip-ties. So the question remains... do we still care? Or did anybody even read all the way down?

Now features a big flat space that will happily hold your RFID access card, token or whole wallet. No more fumbling and trying to get a card to stick to the side of the box
Dedicated holder for USB-sticks, the laser-cutter key and the focus distance measurement spacers.
Dead-Person-Button - remaining time indicator lights are more diffused by the cover and thus more muted.

The basic logic remains the same.Â Once you went through the laser-cutter introduction and got access, just put your RFID token on top of the reader. The beep and the green bar indicates the laser is now hot and you can start cutting. Press the DeadPersonButton while the bar is still green to indicate you are watching and realraum hasn't burned down yet. Remove the card when you're done.

Last Friday we went on an afternoon trip to the nice city of Maribor in Slovenia, less than one car hour from Graz, to met Shuttleworth Foundation Fellow Luka and BoÅ¡tjan of IRNAS, their Institute for development of advanced applied systems RaÄÂe and watch dem develop Open Source Hardware as well as do some DIY BioHacking.

Check out our gallery and see some nice photos of their DIY BioLab, the hardware developement lab and the newest Koruza Prototypes.

IRNAS is located on the 2nd level of the Creative center Tkalka, right in the city center. The building also hosts a big CoWorking Space and an even more impressig Fab Lab, the Kreator:Lab.Â There is even a small beer lab.

Some Projects of note:

Koruza: Is an IRNAS developed open-hardware free-space optical network system, which connects your network via a 1 Gbps laserlink

SafeCast: is an open-hardware geiger counter, already well known of the SafeCastMap

GoodEnoughCNC Family: is a three axis system used in 3D Printer projects like the Troublemaker or cheap CNC mills or even a DIY plasma cutter.

â€Å¾Schnell, schnell! Wir brauchen noch ein wunderbares und nicht kÃ¤uflich erwerbbares Geschenk fÃ¼r Mama, Papa, Opa, Oma und meine 2 Geschwister. Alles individuell auf die jeweilige PersÃ¶nlichkeit zugeschnitten.â€œ Â ...tjaaa, da wirdâ€™s meistens schon etwas eng mit der Geschenks Auswahl.

Aber zum GlÃ¼ck sind viele Leute kreativ und kÃ¶nnen sich dafÃ¼r etwas ausdenken. â€Å¾Heureka!â€œ, ruft dann der erhellte Geist und verweist einem auf den Vorschlag, man kÃ¶nne doch kleine Skulpturen der jeweiligen Lieblingstiere schenken (ich selber sammle seit Kindesalter allerlei Figuren von SchildkrÃ¶ten). â€Å¾Super Idee, Gehirn. Aber wie soll ich das anstellen? Wie soll ich meine Idee in die Praxis umsetzen?â€œ

Und hier kommt der Realraum ins Spiel! Hackerspaces dieser Art sprÃ¼hen geradezu nur von KreativitÃ¤t und Handlungsdrang, vor allem wenn sie so gut ausgestattet sind wie wir ;)Â Ob Holzgeschnitze, sÃ¤mtliches GedrÃ¤hte (also Draht) zum Biegen und LÃ¶ten, dÃ¼nne Holzplatten, verklebbare Teile oder individuelle Kunstwerte aus Plastik,â€¦mit unserer Werkbank, dem Lasercutter oder dem 3D Drucker sind die MÃ¶glichkeiten mannigfaltig. Wer noch ungeÃ¼bt ist mit dem Umgang jener GerÃ¤tschaften kann sich natÃ¼rlich Hilfe von den Mitgliedern holen, besser 3x nachgefragt als 1x kaputt gemacht.

So hat man schnell das passende Geburtstagsgeschenk gefunden, in dem Fall mit dem 3D-Drucker selbst erstellt. Wer der Meinung ist, wenig Zeit oder nicht kreativ genug dafÃ¼r zu sein (so wie ich :P ) kann sich genug Models und Vorlagen aus dem Internet holen.

Am Samstag, den 10. Dezember 2016 fand die GrÃ¼ndungsversammlung des Vereins "World Privacy and Identity Association (WPIA)" bei uns im realraum in Graz statt.

Die WPIA macht es sich zur Aufgabe

das Wissen im Umgang mit den neuen Techniken einem breiten Publikum zugÃ¤nglich zu machen
die Kenntnisse Ã¼ber digitale KommunikationsmÃ¶glichkeiten zu fÃ¶rdern
das VerstÃ¤ndnis zur Abwehr mÃ¶glicher Bedrohungen und Gefahren zu wecken
zur Erarbeitung und Anwendung von LÃ¶sungen beizutragen, mit denen jeder Einzelne seine Rechte auf Wahrung der Vertraulichkeit sowie Wahrung seiner persÃ¶nlichen IdentitÃ¤t und IntegritÃ¤t stÃ¤rken und durchsetzen kann.

Die GewÃ¤hrleistung der Sicherheit in der digitalen Welt ist ein Rechtsgut, zu dem die WPIA ihren Beitrag leisten wird.

Die GrÃ¼ndung am Tag der Menschenrechte 2016 erfolgte,

in der Hoffnung, dass die grundlegenden Rechte der Menschen ohne EinschrÃ¤nkung auf die digitale Welt Ã¼bertragen werden
in dem Wissen, dass die weitere Entwicklung der Rechte der Menschen in Bezug auf die digitale Welt stÃ¤ndig weiterer Anstrengung bedarf
in der Hoffnung, dass die weltweite Entwicklung der neuen Kommunikationstechnologien das friedliche Miteinander der Menschheit fÃ¶rdert
in dem Wissen, dass gleichermaÃŸen die Risiken und Gefahren der neuen digitalen Technologien alle Menschen existentiell bedrohen
in der Hoffnung, dem einzelnen Menschen die Vorteile und positiven Aspekte der neuen Technologien nÃ¤her zu bringen
in dem Wissen, dass Vorbeugung und Vorsorge gegen die neuen Risiken und Gefahren nur durch Wissensvermittlung erfolgreich bewÃ¤ltigt werden kÃ¶nnen
in der Hoffnung, einen positiven Beitrag zur zukÃ¼nftigen Entwicklung aller zivilen Gesellschaften leisten zu kÃ¶nnen.

Das Jahr 2017 fÃ¤ngt schon cool an. Im JÃ¤nner machte ein Video einen viralen Rundgang durch die Science-Szene und preiste eine "centrifuge for 20 cent"an....ich so, whaaaat? Was ich anfangs fÃ¼r einen Hoax hielt stellte sich als eine ziemlich geniale Idee heraus.

Wer von euch kennt das Kinderspiel wo man mit einem Knopf und einer Schnurr mit bisschen Geschick zum Surren brachte? Ich weiÃŸ noch, dass ich es im Kindergarten mal probiert habe und auch meine GroÃŸeltern noch mit diesem Spiel aufgewachsen sind,...man brauchte immerhin nur einen Knopf und ein StÃ¼ck Faden. Man hÃ¤lt die Schnurr an beiden Enden mit den HÃ¤nden fest wÃ¤hrend sich in der Mitte der Knopf drehte, sofern man im richtigen Moment an den Enden zieht.

Bioengineers aus Stanford haben dieses Kinderspiel weiterentwickelt und daraus die "Paperfuge" gebastelt. Ein Hand betriebenes GerÃ¤t mit einer Scheibe anstatt dem Knopf, welches Leistungen von 120.000 rpm (rounds per minutes) schafft,...die Ã¼bliche Tischzentrifuge im Labor schafft 14.000 rpm.

https://www.youtube.com/watch?v=pPePaKnYh2I

Wahnsinn, eine tolle Idee, denn viele schnelle Analysen Ã¼ber Infektionskrankheiten benÃ¶tigen Zentrifugen als Arbeitsschritte, wie z.B. die Trennung von roten BlutkÃ¶rper und Serum. Aber was tun, wenn man weder Strom noch die passende AusrÃ¼stung dafÃ¼r besitzt? Diese Pagerfuge kÃ¶nnte dafÃ¼r die LÃ¶sung sein.

Welche weiteren EinsatzmÃ¶glichkeiten, auÃŸer Blutproben,Â diese revolutionÃ¤re Erfindung noch hat mÃ¶chten wir im OLGA heraus finden und haben uns selber dieses GerÃ¤t gebastelt.

Erste Versuche mit einer Bakterien Zellsuspension sind vielversprechend. Nach ca. 5 Minuten "spielen" wurden die Zellen am Boden eines 0,2 mL ReaktionsgefÃ¤ÃŸes pelletiert.

Neben unterschiedlichen Modellen, Formen und GrÃ¶ÃŸen kann man noch das zu zentrifugierende Volumen als auch die Art der Probe versuchen zu variieren,...es gibt also noch viel auszuprobieren. Im Labor haben wir viele Arbeiten, welche Zentrifugationsschritte benÃ¶tigen (DNA-Isolierung, Proteingewinnung, schlichte Abtrennung von Zellen aus LÃ¶sungen, usw.) und ich kann mir gut vorstellen, dass, wenn die Paperfuge sich experimentell als qualitative Alternative zur Ã¼blichen Tischzentrifuge heraus stellt, dies fÃ¼r viele Analysen-Labore in EntwicklungslÃ¤ndern eine gÃ¼nstige, Strom-unabhÃ¤ngige und schnelle Hilfe darstellen kann. Das Potenzial ist hoch, genau wie die Motivation :D

dsc_6278-jpg Last Monday, RÃ¼diger Trojok made a short stop at realraum on his way through Graz and gave a live Demo of OpenDrop, a cool BioHacking Hardware project of his that he has spent more than the last two years working on.

Opendrop, moves tiny drops of fluid (preferably water based) across a surface by way of electrostatic force manipulation.

It can arbitrarily mix or split drops of various chemicals or from various samples. Making it the ultimate microfluidic chemistry or molecular biology lab.

Or one can just use it to ... you know ... play pacman with colored drops of water.

Whatever the usecase, watching the tiny droplets zoom across the foliated surface, moved by an invisible force is quite awesome to watch. Science seldom looks so cool!

Etwas "grÃ¼nes" zeigt sich im Schaufenster vor'm r3. Was hat es mit diesem "eye-catcher" wohl auf sich?

Viele, die mich kennen, wissen, dass ich ein Freund von KrÃ¤utern bin. Sowohl im botanischen Sinne, als auch in der KÃ¼che in Form von GewÃ¼rzen und Tees. Umso mehr freute ich mich Ã¼ber ein Geschenk meines Vaters, der mir ein ungebundenes Buch seines GroÃŸvaters zukommen lies. Dieses Werk mit dem Titel "Heimische KrÃ¤uter und Pilze, eine reizende Bildersammlung" (gewidmet einer namenhaften Feigenkaffee-Fabrik in Wien) ist wahrscheinlich zu Beginn des 20. Jhd. entstanden, im Buch sind leider keine Datumsangaben zu finden und im Internet finden sich neue Auflagen um 1925 herum.
+Die vergilbten Seiten sind schon etwas brÃ¼chig, dennoch waren die Hand gemalten Abbildungen und der dazu gehÃ¶rige Text in altdeutscher Schrift noch gut zu erkennen. Es ist Ã¤uÃŸerst interessant zu lesen (Altdeutsch ist nicht so schwer wie es anfangs aussieht ;) ), wie in damaligen Zeiten das Wissen in schriftlicher Form zusammengefasst und niedergeschrieben wurde, auch wenn es sich aus heutiger Sicht nicht um besonders detaillierte oder umfangreiche Arbeiten handelte. Auch sei der Wahrheitsgrad dieser "Fakten" anzuzweifeln, aber dies sei natÃ¼rlich bei sÃ¤mtlichen historischen Wissen der Fall.

Doch geht auch dieses Wissen aus einer Reihe wissenschaftlicher Richtlinien hervor. Die binÃ¤re Nomenklatur in Latein, welche vom schwedischen Naturforscher Carl von LinnÃ© seit dem 18. Jhd. eingefÃ¼hrt wurde, ist ein wichtiges Prinzip und die Grundlage der botanischen (und zoologischen) Taxonomie und weiters der Systematik. Dadurch sind Untersuchungsobjekte fÃ¼r ForscherInnen eindeutig deklariert. Auch sind die Beschreibungen der diverser Erkennungsmerkmale und Eigenschaften dieser Pflanzen fÃ¼r die Wissenschaft ein wichtiges Gut, und wer wÃ¼rde heute noch wissen, dass GÃ¤nseblÃ¼mchen weiÃŸe BlÃ¤tter haben, wenn es nicht jemand mal so beschrieben hÃ¤tte?

Gerne schmunzel ich Ã¼ber die "mÃ¶gliche medizinische und pharmazeutische Wirkung", die manchen Pflanzen her aufgrund empirischer Erfahrung, aber auch wegen vorhandenen Aberglauben, nachgesagt wurden. DASS viele KrÃ¤uter, Wurzeln oder BlÃ¼ten (oder Pflanzen allgemein) gewisse Auswirkungen auf tierische KÃ¶rper haben war schon damals nicht zu leugnen, allerdings haben sich die wissenschaftlichen Disziplinen, deren Untersuchungsmethoden und die daraus resultierenden Erkenntnisse stark verÃ¤ndert.
+

Um diesen historischen Schatz, dieses Wissen und die Vorstellungen damaliger KrÃ¤uterliebhaberInnen auch noch fÃ¼r weitere Generationen zu bewahren, habe ich die Seiten mit der uns heute zugÃ¤nglichen Technologie "konserviert" ---> Ã¼blicher Scanner und digital abgespeichert :P ), denn auch Bio-/Hacker sollten den Wert auf die Wissensvermittlung (open source/ open acces) legen, damit Andere von unseren Erkenntnissen profitieren kÃ¶nnen. Die mit Fakten argumentierte Dokumentation ist fundamental fÃ¼r die Erhaltung der Wissenschaft.

Und wer weiÃŸ, vielleicht hÃ¤ngen im Jahre 2500 auch ein paar Seiten Ã¼ber "Linux, leicht gemacht" in Schaufenstern von Future-Hackerspaces und wundern sich Ã¼ber diese "antiken Programmiermethoden" ;)

Die MakerFaire Vienna 2017 #mfv17 ist vorbei, doch die NÃ¤chste kommt bestimmt.

FÃ¼r uns war es die erste MakerFaire auf der wir als Hacker-/Maker-space als Aussteller vertreten waren.
+DafÃ¼r tackteten wir auch mit einem 3 Tische-Stand gleich am Anfang der Stiege sowie einem einstÃ¼ndigen Programmierworkshop auf.
+Toll dabei war also nicht nur das GesprÃ¤ch mit all den anderen teilweise angenehm gleich verrÃ¼ckten Ausstellern.
+Was wir besonders geschÃ¤tzt haben, waren die Besucher welche sich mit leuchtenden Augen fÃ¼r unsere Projekte und Hacks interessiert haben.
+All die Interessierten die mehr Ã¼ber DIY Technik und das Einfach-Selber-Machen wissen wollten und denen wir auch allerhand interessantes erzÃ¤hlen durften.

Wolltet ihr immer schon mal selber Insekten zÃ¼chten?

Eines unsere neuen Mitglieder prÃ¤sentiert nÃ¤chste Woche Mittwoch den 6. Dezember um 19 Uhr ihre Projekte mit Insekten im realraum. Schaut vorbei wir freuen uns auf euch Hier ihre Einladung:
+

Hallo Leute,
+

ich mÃ¶chte euch eine kurze Ãœbersicht geben Ã¼ber die umfangreichen Insekten Projekte.

Der Ablauf wird wie folgt sein:
+- EinfÃ¼hrung in das Thema mit einer kurzen PrÃ¤sentation und einem Video
+- Anschauungsobjekte vor Ort (mÃ¶gliche Verkostung)
+- Problemstellungen und Ziele der Projekte
+- Brainstorming

Im Anschluss gemeinsames GlÃ¼hweintrinken in der Stadt fÃ¼r alle die Lust und Laune haben. Es gibt zu diesem Thema sehr viel zu besprechen und ich bin unter anderem gespannt auf euren Input. Ich hoffe euch ein wenig neugierig gemacht zu haben und freue mich auf einen regen Austausch. Vor allem wÃ¼rde ich mich freuen, wenn Leute aus verschiedenen Sparten kommen, damit man unterschiedliche Meinungen hat. ;)

Insektische GrÃ¼ÃŸe
+Lisa Schaden

PS: Falls jemand Lust hat wÃ¼rde ich mich freuen, wenn ihr bei unserer Umfrage mitmacht. Wir brauchen noch einige Teilnehmer. https://survey2.edu.uni-graz.at/survey/index/sid/667388/token/hz4e9xujhvaxzvi/lang/de

Teilweise ist es etwas schwer mitzubekommen was sich im realraum so tut,
+denn es tut sich praktisch jeden Tag immer ein bisschen etwas. Je nachdem wer da ist,
+wird an dem einen oder anderen Projekt gearbeitet.

Daher mag ich hier mal kurz auflisten was sich heute so an einem ganz normalen Sonntag getan hat,
+das mich (mit)betroffen hat und daher ein kleiner aber feiner Ausschnitt davon ist, was heute passiert ist.

+ + + + + + + + + + + + + + + + + +


LaserVentilationIndicator	DeadPersonButton Labels	r3 Logo LED Fluter	Schleimpilz	Bioreaktor

Bug in der LaserlÃ¼ftungsindikatoranimation auf der LED Pipe gefixt.
Zwei Lasercuttereinschulungen gegeben
den Laser-Dead-Person Button der regelmÃ¤ÃŸig betÃ¤tigt werden muss, besser und deutlicher beschriftet. AuÃŸerdem die Wiki Beschreibung fÃ¼r den Laser aktualisiert.
Ein LED AuÃŸen-Flutlicht montiert, das jetzt unser LOGO erhellt!
an einem Printer-Server-Beaglebone-Image fÃ¼r unseren Laserjet 8000 gearbeitet
OLGA Treffen mit EinfÃ¼hrungstalk in DDD's Schleimpilzprojekt.
Basteln einer Box fÃ¼r eine LED Wort Uhr
Basteln an KisteneinsÃ¤tzen fÃ¼r die Wurmfarm
Etwas aufgerÃ¤umt

Nebenbei wurde noch Ã¼ber Amateurfunk, Weltraumtechnologie, Kryptographie, PrÃ¼fungen und Molekularbiologie gesprochen, doch das hab ich nur mit einem 1/4 Ohr mitbekommen.

Nehmt micht aber nicht beim Wort, sondern schaut an einem beliebigen Abend einfach mal selbst bei der TÃ¼r herein! :-)

[caption id="attachment_928" align="alignright" width="300"] 1: Engraving Metal[/caption]

Years ago we got some horribly expensive foil needed to engrave metal using our laser-cutter. Today is, as far as I know, our first attempt to actually use it.

People always seem to search for a lighter, but then forget to put them back. As a result, even the safely stored ones can never be found when a Bunsen needs to be lit (which we actually have an Piezo for that the evil smokers don't want to steal) or a flame is needed for some project.

Reason enough to make a big deal out of nothing and sponsor an old but sturdy quality Zippo and mark it permanently with the r3 Logo!

Obviously the Zippo was empty. Just to be safe.

[caption id="attachment_929" align="alignright" width="300"] 2: finished engraving with foil still attached[/caption]

Afterwards the burned foil needs to be removed and the surface cleaned.

Finished is the engraved lighter. Not so bad for a first attempt, even though the result could be even nicer. Laser-speed was set to 10mm/s and power to 100% of the 60W.

Not to self for next time: don't trust the red positioning dot without checking if it still corresponds to the actual laser position. The graphic was offset by a few mm. Still worked out though.

Works! The final working result is now stored in the drawer in Masha. As engraved on the lighter. :-) The lighter fluid is right across from it on the shelf.

Have fun and put it back!

Was machen MikrobiologInnen, wenn sie gerade nicht im Uni Labor stehen?

NatÃ¼rlich eigenstÃ¤ndig Umweltproben sammeln und im OLGA kultivieren! Dabei finden sich immer wieder spannende Organismen wie z.B. diese Bakterien aus einer Bodenprobe. Nach mehrmaligem Ausstreichen wachsen einzelne Kolonien auf der Platte. Gut zu erkennen sind dabei die rÃ¶tliche FÃ¤rbung und die schleimig, glÃ¤nzende OberflÃ¤che.

Um solche Projekte Ã¼berhaupt durchfÃ¼hren zu kÃ¶nnen mÃ¼ssen aber erst einmal die Arbeitsmaterialen vorbereitet werden. Damit die Bakterien nicht hungern wurde vergangenen Sonntag Agar mit verschiedenen NÃ¤hrmedien vermischt und in Platten gegossen.

[caption id="attachment_967" align="alignnone" width="300"] steriles Arbeiten mti dem Brenner[/caption]

Auch Bakterien essen gerne Suppe - Rindssuppe als Vollmedium

Ihr sollt wachsenâ€¦ aber du nicht! -Â MacConkey als Selektivmedium

Das Ergebnis kann sich auch farblich sehen lassen

Gut vorbereitet starten so nun wieder neue Projekte Ã¼ber die im Laufe der nÃ¤chsten Wochen noch mehr berichtet wird.

Alles in allem also wieder ein entspannter Open Lab Day in gemÃ¼tlicher AtmosphÃ¤re.

Im Sommer wurde eine Gel-Elektrophorese (unten links) vor der Verschrottung gerettet. Wieder voll funktionstÃ¼chtig trennt man damit DNA Fragmente der GrÃ¶ÃŸe nach auf. Â Im rechten Bild sieht man die von unserem Biohacker Esef selbst gebaute DIY Gel-Elektrophorese, die am Sonntag ihren ersten Einsatz mit DNA Proben und Plasmiden hatte.

Die verwendeten DNA Proben wurden von Studierenden wÃ¤hrend den Uni Kursen hergestellt, welche im Anschluss Ã¼blicherweise entsorgt werden. Am Sonntag haben sie dann doch noch einen Nutzen gefunden.

Ein kleines Agarosegel StÃ¼ck wird mit einem 1kb Standard, einem bekannten Plasmid und mit einer unspezifischen DNA Probe beladen. Nach der Elektrophorese lassen sich DNA Fragmente noch nicht gleich erkennen. Um sie sichtbar zu machen fÃ¤rbt man die Proben mit einer fluoreszierenden Substanz (RotiÂ®-Load DNAstain) ein und hÃ¤lt sie unter UV-Licht.
+Im unteren Bild links ist ein 1kb Standard aufgetragen mit dem man die GrÃ¶ÃŸe der Plasmide, welche als dÃ¼nne Banden im oberen Bereich des Bildes aufscheinen, abschÃ¤tzen kann. Die dicken hellen Banden kÃ¶nnen RNA-Wolken, unspezifische, abverdaute oder abgebrochene DNA StÃ¼cke, in Form von sogenannten â€Å¾Schlierenâ€œ sein. Sehen zwar interessant aus, sind aber unbrauchbar.

Im Vergleich zur Standard Gelelektrophorese bei der man UV-Licht nimmt, verwendet Esef blaues Licht. Um die fluoreszierenden DNA Banden im Gel zu erkennen, sieht man durch den orangen Filter, der sowohl Deckel, als auch als AuÃŸengehÃ¤use der Apparatur ist.

+Anstatt nach Protokoll das Gel 16h lang mit geringer Konzentration einzufÃ¤rben, probierten wir eine hoch-% Methylenblau-LÃ¶sung aus, welche das Gel viel zu intensiv fÃ¤rbte (zu sehen als schwarz blaues Rechteck links unten).

In einer 96-Well-Platte wurden pro Well 100 ÂµL LB Medium mit unterschiedlichen Antibiotika pipettiert. Dadurch hat man Ã¼berprÃ¼ft, ob die Ã¼ber Monate/Jahre gelagerten Stock-LÃ¶sungen noch das Wachstum von Mikroorganismen hemmen kÃ¶nnen oder ob sie schon ihre Wirkung verloren hatten.

FÃ¼r das Experiment wurden die einzelnen Wells mit dem Bakterium E.coli K12, ein klassischer Laborstamm, beimpft und Ã¼ber Nacht bei 37Â°C inkubiert. Die Antibiotika, die ihre Wirkung verloren hatten (TrÃ¼bung des Mediums aufgrund Bakterienwachstums), wurden entsprechend entsorgt.

At home, my Samsung laser-printer uses 15W during standby. So, a few years back, in order to save power, I put it on a USB-controlled power-plug. Pretty soon I added a tiny script that would query cups if a print-job was queued and would switch the printer on and afterwards off again. It turned out to be a pretty effective power saving measure.

+ usbpowerswitching

Our two very big and reliable printers at realraum were even more power hungry, so I wanted to to something similar for the space.

Using the hardware I had on hand, I cobbled together the following:

* A BeagleBone Green to act as cups print-server and to run the python scripts.
+* An empty 230V power-plug case, housing a 5V power-supply (for the BB) and a small opto-coupler isolated relay to switch the plug.
+* A second power-plug case with a second small opto-coupler isolated relay.

While there is a lot of room for optimization, like a leaner BeagleBone image and better housing for the power-plugs, printing- and power-saving-wise it works very well.

As always you can find our code on Github. Stay tuned for updates.

The more complex a program or application, the more likely it contains exploitable or otherwise dangerous faults. Containers are a way of limiting the damage by limiting an application access to the bare minimum. Ideally we would have a separate and instantly replaceable computer for every little daemon and service we run. Sadly, even with virtual machines, this would hardly be an efficient use of resources, so containers try to find a middle ground by allowing us to separate applications almost as if they were running on different machines, while actually sharing the same hardware and operating system kernel.

Several features come together to make this possible:

chroot
namespaces
cgroups

And it is a good idea to augment them with others:

seccomp-bpf syscall filter
packet filtering (ebtables)
virtual network devices
apparmor

Armed with these keywords, your week should now be filled with interesting and productive reading. :-)

If all you want are some opinionated basics however, read on:

How to use a container?

The more containment and separation between applications, the more secure a system gets.
+Unfortunately few applications come with ready-to-use definition of what access and other applications it requires to function at a minimum. There are ways of finding this out (makejail, documentation, strace, apparmor profiles), but it will always involve some work.
+You have to find your own balance between the security one requires and the effort needed to attain it.

Furthermore, what even is an application? Is it a single program or daemon? Or a bunch of programs running in parallel and working in concert towards a single purpose?

How to NOT use a container?

Sometimes (web)developers see the Linux systems that run their (web)applications as a house of card that they better not touch or they don't want to deal with security and quality policies of various Linux distributions. The reason being, that if it works for them, it should work just like that for the end-user. Conveniently containers now allow us to package an applications plus the whole linux ecosystem around it. Unfortunately this just makes everything worse. It makes it harder to actually secure and separate applications from each other while providing a false semblance of security.

What is chroot and what can and can't it do?

A chroot is a root file system (e.g. a whole Linux distribution) inside your host root file system in which a program runs.
+The idea being that a chrooted application can not access any file outside it's chroot.
+Obviously then you have to provide (duplicate) all the tools and applications that will be needed inside the chroot filesystem.
+Tools like debootstrap help installing a debian linux inside a directory or image.

Chroot does not restrict assess to the network, syscalls, hardware devices like usb etc.
+E.g. The root user inside a chroot can easly read harddisk device or re-mount it inside the chroot and do whatever he/she pleases.

Links to some great introduction to cgroups I came across

The RedHat-blog has some very good hands-on introduction articles on cgroups called "World domination with Cgroups" I suggest you read them:

Restrict services using systemd unit files

Sometimes you just want to contain a single executable. In that case you might not truly need a full machine, you can chroot a service and restrict it just using it's .service file.

My favorite: SystemCallFilter! it filters what syscalls a process is allowed to use.

e.g. you could run a program or bunch of programs with strace -c -- and put the list of syscalls at the end in the systemd unit file.

Other extremely useful directives you should read up on:

ProtectHome=read-only || true
+ProtectKernelTunables=yes
+ProtectSystem=strict || full || true
+ProtectControlGroups=yes
+PrivateDevices=true
+#DevicePolicy=closed
+#DeviceAllow=/dev/urandom r
+#DeviceAllow=/dev/random r
+NoNewPrivileges=true
+ReadWritePaths=
+ReadOnlyPaths=
+InaccessiblePaths=
+PrivateNetwork=
+MountFlags=
+AmbientCapabilities=
+CapabilityBoundingSet=

chroot:

RootDirectory=

What about containers as virtual machines replacement? Enter systemd-nspawn

systemd-nspawn is systemd's tool to run containers like you would a virtual machine. Thus 'nspawn containers are called "machines" and are managed with the tool machinectl. Actually machinectl interfaces not only with systemd-nspawn but also rkt, docker, libvirt and others, thus providing a convenient place to manage all your running virtualisations at once.

Putting our application into an container.

Easy! Create a chroot under /var/lib/machines/examplecontainer/ and a permission/network/container configuration-file /etc/systemd/nspawn/examplecontainer.nspawn. Then boot it using machinectl start examplecontainer. Done.

Example examplecontainer.nspawn

+[Exec]
+Boot=yes
+PrivateUsers=no
+
+[Network]
+## put container (together with other containers)
+## in a virtual private network-bridge called "examplevlan"
+Zone=examplevlan

Heute hatten wir einen kurzen Aha-und-WTF-Moment beim Basteln eines WIFI-fÃ¤higen Brandmelders (ESP8266 der im Alarmfall von der Brandmelderbatterie bootet und eine SMS schickt):

Wir versorgten den Melder mit einem Labornetzteil (9V) und maÃŸen Signale mit dem Oszilloskop. Als wir den PrÃ¼fspitzen-GND mit GND der Schaltung verbanden... funkte es kurz! Wie kann dass denn sein?

Daher Multimeter her und mal durch messen! Mhhh, da liegen 9V zwischen dem Minuspol des Labornetzteils und dem Oszi-GND bzw der Oszi-ERDE. WTF^2?

Eine oberflÃ¤chliche Untersuchung des Labornetzteil lieÃŸ gleich vermuten dass die Ursache hier zu suchen sei. Darin scheppert's! Schraubenzieher her und siehe da, jemandem sind aus der darÃ¼ber stehenden blauen Sortierbox Unterlegscheiben gefallen und zwar genau in die LÃ¼ftungsschlitze des Labornetzteils. Diese haben im Netzteil einen Kurzschluss zwischen DC+ und dem GehÃ¤use verursacht. Das GehÃ¤use ist natÃ¼rlich geerdet, so war DC+5 Ã¼ber die Erdung des Stromnetz mit der Erde des Oszilloskop kurzgeschlossen.

Das erklÃ¤rte auch die anfÃ¤nglichen Messergebnisse. :-)

MÃ¶gen in Zukunft bitte Alle aufpassen, dass Nichts in die LÃ¼ftungsschlitze der Labornetzteile fÃ¤llt. Es hÃ¤tte ja auch wirklich etwas kaputt gehen kÃ¶nnen!

Read about Flocx's current project, a battery-saving WIFI+MQTT-enabling cheap smoke-detector here: https://blog.flo.cx/2018/08/ikea-diy-smart-smoke-detector/

I wanted to do the same thing for my flat, but instead of using the IKEA one, I ordered two cheap 7â‚¬ SmartWares detectors from Amazon with 9V batteries that are advertised to give 5yrs battery life and otherwise identical hardware. Also instead of ÂµPython I used Sming and C++. Just for the fun of it, I also added a voltage divider that measures the battery voltage at the time of alarm.

You can find my firmware on GitHub.
+
+
+
+Todo for the future: motivate someone to do this for realraum. ;->

Since all 9V smoke-detectors ICs basically use the same pinout with an I/O-function on pin 7 that pulls LOW when no smoke is detected and HIGH on alarm, they are all equally easy to mod. The SmartWares are smaller than the IKEA ones though, so I did not even attempt to fit everything inside the case. More accessibility traded for lower WAF :)

Note that there are 3V Lithium 10yrs battery life smoke detectors out there, which work a bit differently. For once, the ESP8266 does not run with 3.0V but needs true 3.3V, so at the very least you will need a cheap and tiny boost converter from AliExpress. Furthermore, they do not use a CS2105G0 based chip but a PIC which might not have an pin as CS2105G0-I/O-pin configured.

A word of warning: In order to conserve the battery, the circuit disconnects the whole GND when no smoke is detected. Thus GND and 3V3 of the ESP8266 may be short-circuited through the unpowered buck-converter, depending on your component. So just to be safe, remove the Wemos from the circuit before connecting it via USB.

As a hackerspace we regularly host user-groups and irregularly host talks and workshops and all of them need to use our beamer. Quite a downer then, that our beamer's HDMI and DVI Input stopped working with newer laptop graphic cards. Especially since VGA started having it's own issues: Dark slides transmitted over our long VGA cable cause the beamer to decide input has disappeared and switch the input off.

A look at the kernel messages with dmesg made the source of the problem immediately apparent. The CRC of the EDID the beamer sends over the HDMI/DVI cable is wrong. (Interestingly enough, the beamer EDID sent over VGA is fine). As a result, newer laptops decide that no HDMI/DVI cable has actually been attached. Nothing you can do. Certainly not with any user tools like xrandr or any Xorg driver or kernel module options. Believe us, we tried it all. (Even if a software solution would have been possible, it would certainly not have been convenient to hack each new speaker's laptop and OS of choice on the spot.)

This needed fixing!

Rather than risking our beamer in a hunt for its EDID flash, which we might be able to re-flash, we decided to man-in-the-middle the cable and spoof the EDID sent by the beamer. A couple of ready-made solutions can be had on Amazon for anything from 30â‚¬ to 150â‚¬ but only one supports our beamers native resolution of 1280x800 and costs a whooping 75â‚¬.

We're hackers however, and so built our own solution for <10â‚¬ from materials already lying around.

First we cut open a HDMI extension cable extracted the DDC wires as well as HDMI 5V and GND. DDC just uses I2C so in theory we can use any ÂµC, connect the DDC wires leading to the host device (laptop) it's SDA/SCL pins, make it answer requests for EDID information and be done.

There is even a ready made firmware project for an AVR ATtiny on GitHub which allowed us to get started right away and save a lot of time. (Beware the code is a bit crappy, can only send a single EDID and has problems with high-byte EDIDs, aka almost every modern EDID)

We used an ArduinoNanoV3 as a programmer for the ATtiny and after fighting the firmware a bit (high-bytes), managed to find an EDID setting that would both compile and result int a laptop-hdmi-signal that was accepted by our beamer. It's a weird 71.9 Hz signal, but it works reliably at native 1280x800. The lack of additional EDID modes might even be a boon, since it prevents laptops with different aspect ratios to autoselect a resolution that would yield crappy results.

Finally we soldered the cable's wires onto a 8pin socket and put whole thing in the casing of a dead H801. That way we still have the option of flashing better settings and firmware onto the ATtiny in the future. Add a few zip-ties for mechanical stability and voilÃ : Working HDMI port.

Note the zip-tie securing our hack to the fat HDMI extension.

ChaosCamp2015

Wir freuen uns darauf diesen lang erwarteten Dokumentarfilm am 11.11. um 20:00 im Forum Stadtpark co-prÃ¤sentieren, mit Euch anzuschauen und Euch dort zu treffen, dÃ¼rfen.

Das Crossroads-Dokufestival beschreibt auf seiner Webseite:

â€œEtwas zu teilen kann mehr daraus machen!â€Â
+
Vor vielen Jahren strandete ein Hacker*innen-Raumschiff in unserem Sonnensystem. Um mit verschiedenen Kulturen und Lebensformen Kontakt aufzunehmen, schickte es eine kleine Rakete zur Erde. Wo immer sie ist verbreitet sich Magie wie Feenstaub. Um Wissen und Informationsfreiheit zu fÃ¶rdern, reist die Rakete zu jedem Treffen, das von Europas grÃ¶ÃŸter Hacker*Innenvereinigung, dem Chaos Computer Club (CCC), organisiert wird. Bei diesen Treffen kommen Nerds, Hacker*innen, Maker*innen, Aktivist*innen und andere galaktische Lebensformen zusammen, um sich Ã¼ber Technologie, Gesellschaft und utopische Ideen auszutauschen. In einer Zeit, in der Regierungsweisen, Wirtschaftsformen und soziale Ordnungen in Frage gestellt werden, sind die Herausforderungen jedoch enorm. WÃ¤hrend das Internet strukturell eine grundlegende Erneuerung der Demokratie ermÃ¶glichen wÃ¼rde, wird in immer mehr Staaten eine autoritÃ¤re Wende vollzogen.
+
Begleitet von dem Aufruf â€Å¾Hacking als Denkweise zu nutzenâ€œ tauchen wir gemeinsam mit der Filmemacherin in ein dokumentarisches Abenteuerspiel ein und erforschen auf den Veranstaltungen des CCC wie die Hacker*innenkultur den Herausforderungen unserer Zeit begegnet. In der utopischen Welt von All Creatures Welcome kÃ¶nnen wir sehen, dass unser Leben nicht durch allgemein gegebene Wahrheiten bestimmt wird, sondern durch die Art und Weise, wie wir arbeiten, uns entwickeln, leiden oder trÃ¤umen. So werden die Events des CCC zu einer mÃ¶glichen Vorlage fÃ¼r grundlegende VerÃ¤nderungen der Gesellschaft.

Das Chaos Communication Camp findet zwar nur alle 4 Jahre statt doch die nÃ¤chste Inkarnation ist glÃ¼cklicherweise schon im Sommer 2019! Wer es gar nicht erwarten kann Utopie zu leben, hat vom 27. bis 30. Dezember schon die Chance den Chaos Communication Congress in Leipzig zu besuchen!

Esef und Sanchez haben einen Mini-Workshop fÃ¼r Labor- und Mikrobio-Basics abgehalten. Darunter Medium mischen, Agar-Platten gieÃŸen, Bakterien-/Keimkulturen ausstreichen, pipettieren, mikroskopieren usw.

Ãœber Nacht wurden die Kulturen dann bei 37Â°C inkubiert.

+... und das Ergebnis kann sich wirklich sehen lassen!

Die Keime sind gut angewachsen und zeigen eine intensive Gelb- oder Rot-FÃ¤rbung.

Versuchsweise wurde ein Agar mit Folgemilchpulver gemischt um Laktobazillen anzuzÃ¼chten. Leider sind die Proteine ausgeflockt und haben die gegossenen Platten eher schwer auswertbar gemacht.

Dirty Waters â€“ so nennt sich eine Studie, die vor kurzem von Greenpeace verÃ¶ffentlicht wurde. Der Name passt ganz gut. Es wurden Proben von 29 FlÃ¼ssen in Europa entnommen und auf Arznei- und PestizidrÃ¼ckstÃ¤nde geprÃ¼ft. Darunter auch 3 Ã¶sterreichische FlÃ¼sse: der Schwarzaubach und der Stiefing in der Steiermark und der oberÃ¶sterreichische Sipbach.

Laut Studie konnten dabei in Ã–sterreich mehrere Medikamente, darunter 3 verschiedene Antibiotika und 38 verschiedene Pestizide nachgewiesen werden.

Die Entnahme der Proben wurde in Gebieten durchgefÃ¼hrt, die eine groÃŸe Dichte an Massentierhaltung aufweisen. Die RÃ¼ckstÃ¤nde gelangen durch GÃ¼lle in den Boden und werden durch Regen in nahegelegene FlÃ¼sse geschwemmt.

Vor einigen Tagen gab es zu diesem Thema im OLGA das erste Treffen unseres neuen Projektes â€Å¾La rÃ©sistance vivante â€“ die lebende Resistenzâ€œ. Die Studie bietet uns den Anlass eigene Analysen durchzufÃ¼hren. Besonders interessant fÃ¼r uns dabei, ob dadurch die Gefahr von multiresistenten Keimen steigen kÃ¶nnte. Das Projekt wird Ã¼ber mehrere Monate laufen und umfasst Leute aus der Molekular- und Mikrobiologie, Biologie und Technik.

Falls ihr mehr darÃ¼ber wissen mÃ¶chtet, am Laufenden bleiben oder Interesse habt in irgendeiner Form mitzuwirken meldet euch per Mail, Facebook, riot.im, folgt uns auf Instagram oder schaut persÃ¶nlich vorbei.

As you might know, quite a while ago, our electronics lab TESLA moved to the second flat "W2". There is a lot more space and equipment for electronic hackery now, BUT. We found that sometimes it would be nice to have some basic soldering capability in our main lounge "LoTHR" as well. Fret no more, with our new workbench (Work in Progress) we also set up a a micro electronics area.

These absolute basics currently consisting of:

Soldering Iron (DC/DC mini T12 Station)
Lab-Power-Supply (DC/DC up to 30V / 5A)
a Multimeter

Note that it is not meant to replace TESLA. Just to keep you from moving your project all the way to 'W2" if all you need to do is solder two wires or check one voltage.

Building the micro electronics box

Basically I got us a DPS3005 constant current / constant voltage power supply and a small KSGER soldering station and connected them to a 27V 3.5A power supply.

Then, as per Ernst's suggestion, we put everything into a nice and sturdy box which formally housed external SCSI HDDs.

The front-panel was laser-cut so all the equipment would fit and voila, after a few hours putting everything together, here we are.

As a finishing touch, a T12-soldering-tip-holder was printed and taped to the side.

Further documentation can be found in our Wiki and more photos in our Gallery.

FÃ¼r die Maker Faire und Ã¤hnliche Events benÃ¶tigen wir unbedingt ein Bobbycar mit Allradantrieb. Da es bereits Ã¤hnliche Projekte von Lars und FischÂ gibt, fiel die Wahl auch bei uns Hoverboard Motoren. Diese kÃ¶nnen aus defekten Hoverboards ausgebaut werden.

Die hinteren Motoren wurden an einer Alu Platte befestigt:

img_20190120_011052

Die beiden vorderen Motoren haben 3D gedruckte Halterungen bekommen. Sobald wir eine CNC FrÃ¤se haben, werden wir die 3D gedruckten Teile durch FrÃ¤steile ersetzen. Damit es nicht ganz so schnell kaputt geht, haben wir die 3D gedruckten Teile mit etwas Aluminium verstÃ¤rkt.

Das Bobbycar bekommt in den nÃ¤chsten Wochen noch einen Akku, bestehend aus bis zu 180 StÃ¼ck 18650er Zellen (je nachdem wieviele wir in das GehÃ¤use bekommen). Auch die Motorcontroller mÃ¼ssen noch mit Joysticks am Lenkrad verbunden werden.

Die Maximalgeschwindigeit wurde mit 38km/h berechnet. Bei einem Gesamtgewicht von 100kg und einem Drehmoment von 34Nm pro Rad kommen wir auf 16,6m/sÂ² Beschleunigung was einer Zeit von 0,5 Sekunden von 0-30km/h entspricht. Die fÃ¼r die Beschleunigung benÃ¶tigte Streckt wurde mit 2m berechnet.

Our mini electronics all-in-one box for LoTHR (so people in LoTHR don't have to walk all the way to TESLA for the quick and small stuff), got an upgrade.

The previously empty top slot now features an XY-FZ35 programmable electronic load. Test your power supply, test your batteries capacity, draw a discharge graph, use it in ways not intended by it's makers. (But if you break or brick it, You Replace And Fix It ASAP!)

The tiny cut-out on the top left of the load, features a mini-USB jack where we put an USB serial-TTL converter connected to the GND,TX,RX pins of the load. Using the easy command-set you can indeed periodically poll your batteries discharge rate, voltage on so on.

But even without USB, the thing is pretty nifty and allows you to set a limit on the amount of mAh to draw, or to stop after a specified time, and so on.

Was tun, wenn Antibiotika nicht mehr wirken?

Dieser Frage haben sich zwei schlaue KÃ¶pfe aus unserem OLGA gewidmet. Ãœber einige Monate hinweg experimentierten Daniel Derndorfer und Alex TÃ¶dling mit Bakteriophagen. Das sind Viren, die darauf spezialisiert sind Bakterien zu befallen und abzutÃ¶ten. Somit kÃ¶nnten Phagen eine wirksame Alternative zur herkÃ¶mmlichen Antibiotikatherapie darstellen.

Das gewonnene Fachwissen teilten die beiden dann Anfang MÃ¤rz auf dem Symposium des Ã–sterreichischen Gesundheits- und Krankenpflegeverbandes (Ã–GKV) anlÃ¤sslich des 20-jÃ¤hrigen Bestehens der ARGE Hygiene.

Since our last meeting for the upcoming Chaos Communication Camp 2019, an idea got stuck in my head (many actually, but this post is just about that one):
+Lasercut some trapezoid lamps that make for a cosy atmosphere in our lounge tent. Leave enough space inside to put in any (battery powered) light at hand. Make them easy to assembly, so we just need to transport the sheets of wood and can easily assemble several of them at the location.

After a short discussion on IRC about who had time and ideas for the right approach, I decided to give it a try myself and see what I could do in about half a day.

See photos and videos in the gallery.

First I went looking for a trapezoid box maker. Turns out, there is none that I could find. Here is an otherwise impressive list of joint and box scripts, which I came across.

I decided to draw the box by hand in Inkscape, based on two different sized cubic boxes generated with an Inkscape extension. From these, I would take the top and bottom parts and create the trapezoid sides by rotating the generated finger-joint borders. So far so good. Of course I made a mistake and duplicated the wrong sides, but realized this in time to not waste any wood.

Secondly I wanted the light to shine through an awesome looking design. Maybe throw some geeky shadows.

I went to images.google.com and started browsed for creative commons or copyright free SVGs and designs. Most links went to etsy or Pinterest. That sucked.
+After quickly being fed up seeing price tags for simple SVGs, I decided to try my hand at drawing. Due to time constraints and out of concerns for stability I opted for thicker connections and larger windows instead of many fine patterns. Turns out, even a noob with the r3 Wacom tablet like me, can still manage to get workable results within an hour. Workable as proof of concept, anyway and not at all geeky. (My first attempt with drawing gears failed miserably) Our resident art critic found the result to be to "eso"-inspired for his liking. The direct view onto the lamp allowed by the bigger windows also turned out to be uncomfortable, so I had to glue in some backing paper as diffuser.

Third is the light source. The original idea was, to make enough space so we can put in any (battery powered) light that we might have at hand. I decided to deviate the prototype a bit by re-using the IR-handwave-controlled-light of an old broken Mathmos lamp of mine. All the modifcation that was needed is a cut-out circle at the bottom and the top for the sensor.

Finished Prototype:

+ + + + + +

How did this project fail in it's goal to make a lamp to quickly and easily assemble at CCCamp:

Fail: Glue required for baking paper diffuser, required due to too large windows.
Fail: Glue required for Finger-joints.
Fail: Tools required so trapezoid does not fall apart while glue dries. Assembly took too much time.
Fail: Mistakes made while drawing had to be fixed late with hot-glue, re-drawing and re-cutting.
Concern: turned out to be larger than necessary
Concern: Wood/MDF is recyclable and great for in-tent but maybe less fine for outdoor illumination.

How did this prototype succeed?

It makes a nice enough lamp
Enough space for any light one might want to put in.
The IR-handwave-controlled-lamp-module was successfully revived in this lamp.
I got to play with the Wacom Tablet
It makes a nice in-tent / in-door lamp that will find it's way to CCCamp2019 despite it's failings
Lessons were learned

Lessons learned:

Rather than drawing patterns ourselves, we should use Japanese Fonts: Write Matrix-Style column text using Hiragana and Katakana in small laser-cut-able letters.
Drawing the trapezoid box in Inkscape by hand is way too inflexible and does not allow for quick changes to material thickness or lamp size.
Drawing this in Inkscape by hand was prone to errors.
Wood is great for in-tent/in-doors but requires treatment for outdoor use. At that point we might consider cutting some lamps from Acrylic rather than treating the wood with laminating foil or lacquer.
Big holed patterns make less impressive light patterns even though they allow for more stable sides.
Big holed patterns require a diffuser like baking paper that needs to be glued on.
Don't just copy&paste side panels, remember that joints need to fit together.
Two side panels needs to be less wide by $materialthickness if one wants a quadratic bottom and top.
Finger-joints are a bad choice for quick and glue-less assembly. Examples for designs that might not require glue: [1], [2]

Freie, kreative Forschung, frei nach Interesse & Leidenschaft (z.b. an Ã¶kologisch bedeutenden Themen) statt den Ã–konomischen & Erfolgs-ZwÃ¤ngen der Arbeitswelt und UniversitÃ¤t folgen zu mÃ¼ssen.
Die MÃ¶glichkeit molekulare Biologie in Eigenregie zu erlernen und anzuwenden, ohne vollkommen von den veralteten Lehrmethoden von Schulen und UniversitÃ¤ten abhÃ¤ngig zu sein. Keiner, der sich das anmaÃŸende Recht herausnimmt, darÃ¼ber zu entscheiden wer molekulare Biologie machen darf und wer nicht. (AufnahmeprÃ¼fungen, Knock-OutprÃ¼fungen, â€œBulemielernenâ€Ââ€“> Nein danke.)
Unkompliziertes, fÃ¤cherÃ¼bergreifendes Arbeiten mit Freunden, alleine, oder wie immer man will
Keine Diskriminierung auf Grund von Alter, Schulabschluss, finanziellen Mittelnâ€¦
24/7 Zugang zu einem Labor
ÃœbungsmÃ¶glichkeiten fÃ¼r Studenten ohne stÃ¤ndigen Notendruck, Fehler zu machen ist Ok! Manchmal sogar der grÃ¶ÃŸere SpaÃŸ ;)
UnabhÃ¤ngige DNA Tests, Umwelt Tests,â€¦
Freier Zugang zu Wissen, Open-Source Kultur

Das Ziel des 'Open bioLab Graz - Austria'

Uns treibt ein starkes Interesse an molekularbiologischer Forschung und Technik an, fÃ¼r den kreativen, freien und selbststÃ¤ndigen Umgang damit sowie fÃ¼r interdisziplinÃ¤res und gemeinschaftliches Arbeiten.

Das Ziel des Open bioLab Graz Austria ist folgendes:

Ein offenes Gemeinschaftslabors fÃ¼r Biologie und Molekularbiologie von Forschungsbegeisterten fÃ¼r Forschungsbegeisterte zu unterhalten.

Wir stellen ein fÃ¼r Interessierte frei zugÃ¤ngliches Labor zur VerfÃ¼gung, bieten Platz fÃ¼r kreative, gemeinschaftliche, fÃ¤cherÃ¼bergreifende Projekte, Freude an der Forschung, sowie Lernen von und miteinander. Dabei kooperieren wir gerne mit Schulen, universitÃ¤ren FakultÃ¤ten und begeisterten Einzelpersonen und Personengruppen. Das OLGA ist nicht nur ein Hobby, sondern auch als Inspiration und wertvolle ErgÃ¤nzung zur Bildung. Die nÃ¶tige AusrÃ¼stung wurde und wird laufend Ã¼ber Spenden, Eigenentwicklungen (Thermocycler, Bioreaktor, 3D-Bioprinter) oder aus nicht mehr benÃ¶tigten AltbestÃ¤nden organisiert. WÃ¤hrend es in anderen Fachbereichen wie Elektronik bereits viele entsprechende Initiativen gibt (in Wien z.B. das 'Metalab'), kann man freie Labore fÃ¼r Molekularbiologie in ganz Europa an einer Hand abzÃ¤hlen, sogar weltweit finden sich nur unwesentlich mehr. Sie wurden unter Begriffen wie â€œDIY-Bioâ€Â oder â€œBio-hackingâ€Â bekannt. Wir freuen uns, in Graz eine Ã¶sterreichweite Vorreiterrolle einnehmen zu kÃ¶nnen. Begeisterte Mitwirkende aus anderen Teilen Ã–sterreich und sogar dem nahen Ausland unterstreichen dies.

Wir sind einerseits eine Community von Technik- und Bastel-Begeisterten. Uns macht das Spielen & Experimentieren mit Technik SpaÃŸ. Wir entdecken gerne Neues und wollen von Anderen lernen. Ob Zentrifuge, LÃ¶tkolben, Bits&Bytes, Sensoren, DNA, TCP-Packet, Kryptografie, 3D Drucker, Technik|Gesellschaft, Lasercutter oder Mikroskop, die Interessen sind vielseitig.

Andererseits ist der realraum eine RÃ¤umlichkeit in der Brockmanngasse in Graz, in denen diese Community einen Ort findet, sich zu treffen, auszutauschen, zu basteln, diskutieren, oder einfach nur die Seele bei einem kÃ¼hlen Mate oder Tschunk baumeln zu lassen. Hier ein paar Fotos.

Kurz gesagt: Der realraum ist ein Hackerspace, Makerspace und DIY Biolab.

Die meisten Veranstaltungen sind offen, der Eintritt ist frei. Komm vorbei!

Oder halte deine eigene Veranstaltung bei uns ab.

Hackerspace klingt fÃ¼r mich irgendwie bÃ¶se....

Hacken bedeutet fÃ¼r uns Systeme zu verstehen in man sie mal auseinandernimmt, genau betrachtet und vielleicht auf neue und kreative Art und Weise wieder zusammensetzt. Dinge anders als vorgesehen funktionieren zu lassen, kann Kunst sein oder einfach nur SpaÃŸ machen. FÃ¼r die meisten von uns ist Hacken synonym mit Basteln.
+
Dabei muss es nicht unbedingt immer um Technik gehen. Wir nutzen ReagenzglÃ¤ser um Applaus zu messen, Beleuchtungsstrips um ein Logo zu basteln, GlÃ¼hbirnen um veganes Tempe zu brÃ¼ten, alte Laptopbildschrime als Infokiosk, usw.

In einem Verein gibt es doch einen Vorstand und genau verteilte Aufgaben...
+

Das Hauptaugenmerk unseres Orga-Teams liegt ausschlieÃŸlich darauf die Arbeiten zu erledigen, die minimal nÃ¶tig sind damit der Verein funktioniert: Buchhaltung, Zahlung von Miete und Strom, Postverkehr, Versicherung, Aufnahme von Mitgliedern, etc.
+
Inhaltlich wird der realraum von den AktivitÃ¤ten und Initiativen seiner Mitglieder getragen bzw stellt einfach nur Raum und Infrastruktur fÃ¼r individuelle Projekte oder Interessengruppen/Meetups bereit. Wenn ein gemeinsamer Standpunkte nÃ¶tig ist oder wie der realraum nach AuÃŸen vertreten wird, wird das im monatlichen Mitgliedertreffen diskutiert.

Der physikalische realraum ist ein Vereinslokal in der Brockmanngasse 15 in Graz. Der Raum besteht eigentlich aus mehreren RÃ¤umen, die wir euch im Folgenden kurz vorstellen.

Nach Durchschreiten unserer VordertÃ¼r, stilecht gesichert durch ein elektronisches Schloss Marke Eigenbau, befindet man sich in unsererÂ Lounge for Tinkering / Talking, Hacking & Relaxing / Reading, kurz LoTHR. Wie der Name schon sagt wird dieser Raum vielseitig genutzt und ist auch unser Hauptraum. Dort finden auÃŸerdem die meisten unserer Workshops und Parties statt, Infrastruktur wie Beamer & Leinwand vorhanden. AuÃŸerdem wohnen hier unser Lasercutter und der 3D-Drucker. Des weiteren befindet sich in einer Ecke das Tesla, unser Elektronik-Labor. Besonders abends laden Ambient Light, Stereoanlage, Couchen und eine kleine KÃ¼che zum "socializen" ein.

Der Connector, kurz Cx, verbindet alle unsere RÃ¤ume miteinander. AuÃŸerdem wohnen in diesem Raum unsere Netzwerk-Infrastruktur und unser Raum-Server AlfRED. So nebenbei stapeln sich hier auch die GetrÃ¤nke-Kisten, um immer genug Bier, Mate, Makava und Apfelsaft fÃ¼r die KÃ¼che bereit zu haben.

Ãœber den Connector gelangt man unter anderem in's Open BioLab Graz â€“ Austria, kurz OLGA. Mehr Infos Ã¼ber's OLGA.

AuÃŸerdem findet sich neben dem OLGA noch unsere Werkstatt, auch Machine Shack, oder kurz MaSha, genannt. Hier findet sich Werkbank, Bohrmaschinen, Schraubenzieher & Schrauben, Hammer & NÃ¤gel, SÃ¤gen, ... alles, was man zum Arbeiten mit Holz, Metall und anderen Materialien so brauchen kann.

Eine detaillierte ErklÃ¤rung der RÃ¤ume ist in unserem Wiki zu finden. Ebenso im Wiki findet sich eine Liste aller im Raum verfÃ¼gbaren Werkzeuge.

Die gesamte realraum Infrastruktur, also alle RÃ¤ume, Werkzeuge, Tools und die IT, kÃ¶nnen von allen realraum Mitgliedern genutzt werden. AuÃŸerdem ist es auch ohne Mitgliedschaft mÃ¶glich, den GroÃŸteil unserer Infrastruktur zu nutzen. Einfach vorbeikommen und ein realraum Mitglied fragen!
