One of the most vexing problems when 3d printing is to get the first layers stick properly to the printing bed. How many times I get warped corners. How many times the printer starts pushing the whole piece around the table – especially when I’m not looking and realizing an hour too late that I [...]

a take on ChaN’s wav audio player for the attiny85 – check out his website, really great stuff all over: http://elm-chan.org/   I built several versions for the new exhibition we did for the Centre Nature Pro-Natura Champ-Pittet – some play loops, other are triggered by light barriers and shock sensors just a simple loop [...]

    I’m currently finishing (hopefully) our new twisted-pair-(Cat5, ethernet cable)-based intercom/tally system for our tv projects: communication, data and video all over one network cable (more on this soon) – and I stumbled over several CAT5 cables in our bin that were either damaged or wired the wrong way or simply crossover cables that messed [...]

This is still work in progress (in the same way as the whole gnusb rewrite to make it compatible with the Arduio IDE) but I’d like to share the first impressions of my new Baby-Gnusbuino, a somewhat Arduino compatible thingie based on the ATTINY85. It has a self-etched USB connector and a boot loader based [...]

Trying to print PLA with the Solidoodle was a nightmare so I wanted to add a cooling fan to see if that helps anything to keep the plastic from flowing all over the place. so I downloaded and printed (from ABS) this nice fan duct: added a MOSFET and followed all the instructions here http://www.soliforum.com/post/2316/#p2316 [...]

It’s been a long time I wished to document the building of the control voltage footpedals I use together with the gnusb and the videobass. The basic idea was to build an expression pedal that outputs a voltage according to it’s angular position. I wanted it  to stay in position when not used, so there [...]

This is nothing new and has been done in the security CCTV world for years, but I’m still surprised it was so easy. Thursday we have to make a multicamera capture of the premiere of the Fribourg Opera – in Fribourg’s brand new theatre – which is huge – and we just don’t have enough [...]

Thank’s a lot to Mohammed, who, with great patience, filmed the whole process of building the latest Videobass. Many many hours of sanding have been edited out of this video. Check it out:

I was thinking about this one since doing this exhibition for the ethnographic museum in Zurich: Why not just rip out the colorwheel of a DLP projector to make it black and white? Should be easy and should work, no? It works, and I could stab myself 100times – why didn’t I have the courage [...]

Here we go: For the pan/tilt head I welded together two L-shapes, and connected them with bicycle gear wires to a slightly modified Manfrotto fluid tripod head (501). The best of both worlds: fluid movement, direct control but 2 meters away…   Sketchup-Model of the crane: crane.skp
