We worked a lot with Max and Flo on the Synkie modules at our research week in April, so much that we didn’t take time to blog about it. So here, finally a little roundup of what has happened. Download synkie-modules-20100410 Here’s a ZIP archive  witch Eagle and PDF files and of all modules developed [...]

Today we’ve played around with a new sensor. The Melexis MLX90316 can detect the angular position of a magnet. From it’s datasheet: In combination with the appropriate signal processing, the magnetic flux density of a small magnet (diametral magnetization) rotating above the IC can be measured in a non-contacting way (Figure 3). The angular information [...]

A finished uDMX just before it goes into the XLR connector: uDMX source code and schematics are now hosted on GoogleCode I’ve just submitted the newest version of the uDMX to its brand new SVN repository on code.google.com. Including double sided really small PCB that fits into a Neutrik XLR connector new bootloader based on [...]

At our last concert with Naïma we tested the newest version of the videobass software in”real life”. It has evolved a lot since Thobias Bühler filmed us for the Migros Kulturprozent. It features a new string preview display where you can see the clips around the slected one, a little bit à la Apple’s CoverFlow. [...]

Good resolutions sometimes take a long time, but never give up your hopes! I have finally put the videobass code base under version control: http://code.google.com/p/videobass/source/checkout

I should have done other things today, but the parts for the synkie power supply I’ve ordered yesterday arrived this morning, and the other day I found some aluminum sheets to cut out the front panels at a garbage sale. I couldn’t help but had to build it immediately. It was pretty painless, although we [...]

sk00 power supply Here’s the schematics and the board for the power supply. I have not built it, yet, so I have no idea if it works as intended. Originally, we wanted to supply up to 2 Amps per channel, but when I started to order the parts, I found out that the LM78xx series [...]

The first 2 modules seem to work quite well now. It helped to put 75Ohm resistors in parallel at the outputs of the MAX457 op-amp, to stop it from oscillating. Maybe we should also put a resistor in series as Max has seen on the datasheet? Anyway, the picture quality seems better that expected and [...]

Video signal is a bitch. You cannot just fool around with it like with sound: Besides the much higher bandwidth (~5MHz) which makes designing video circuits much more demanding, the main problem is that video signal contains not only the actual picture, but also synchronization signals. You touch the picture and the sync goes away, [...]
