Immer noch hartnäckig am Kern der Sache interessiert?
Diesen Samstag, den 19.11.2016 ab 20:00 steigt im realraum eine große Party für Maker, Sharer und Denker.
Für Kreative die Schaffen! Ihre Erfahrung, Wissen und Werkzeuge mit der Allgemeinheit teilen, dabei an Dich und
die Welt denken und so auch Dir ermöglichen kreativ tätig zu werden, ohne die Fesseln eines nicht mehr zeitgemäßem
„Schnell, schnell! Wir brauchen noch ein wunderbares und nicht käuflich erwerbbares Geschenk für Mama, Papa, Opa, Oma und meine 2 Geschwister. Alles individuell auf die jeweilige Persönlichkeit zugeschnitten.“ …tjaaa, da wird’s meistens schon etwas eng mit der Geschenks Auswahl.
Aber zum Glück sind viele Leute kreativ und können sich dafür etwas ausdenken. „Heureka!“, ruft dann der erhellte Geist und verweist einem auf den Vorschlag, man könne doch kleine Skulpturen der jeweiligen Lieblingstiere schenken (ich selber sammle seit Kindesalter allerlei Figuren von Schildkröten). „Super Idee, Gehirn. Aber wie soll ich das anstellen? Wie soll ich meine Idee in die Praxis umsetzen?“
Und hier kommt der Realraum ins Spiel! Hackerspaces dieser Art sprühen geradezu nur von Kreativität und Handlungsdrang, vor allem wenn sie so gut ausgestattet sind wie wir ;) Ob Holzgeschnitze, sämtliches Gedrähte (also Draht) zum Biegen und Löten, dünne Holzplatten, verklebbare Teile oder individuelle Kunstwerte aus Plastik,…mit unserer Werkbank, dem Lasercutter oder dem 3D Drucker sind die Möglichkeiten mannigfaltig. Wer noch ungeübt ist mit dem Umgang jener Gerätschaften kann sich natürlich 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 dafür zu sein (so wie ich :P ) kann sich genug Models und Vorlagen aus dem Internet holen.
Shortly after discussing the idea at Geekend16, an awesome person at CCC created this even more awesome calendar event aggregator for CCC associated hackerspaces. It works by grabbing calendar and location information from SpaceAPI.
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 Boštjan of IRNAS, their Institute for development of advanced applied systems Rače 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. 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.
Letzten Freitag nutzten wir einen der seltenen Wartungslot der MedAustron in Wiener Neustadt um den dort befindlichen Teilchenbeschleuniger zu besichtigen. Linearbeschleuniger, Synchrotron, Gentry und alles Dazugehörige.
Updated the Laser-cutter access control box today. Major changes include.
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. 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. Beeps and blinks will indicate that laser is now being disabled.
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.
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.
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 m² 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.
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 top 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). 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
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. 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.
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?
