New kits!


I finally got off my butt and finished documentation for MIDIsense, a simple and inexpensive MIDI/sensor system for artists, musicians and experimenters. I did a workshop with these in March and they worked great so I’m happy that they’re finally available.
The only board I’ve released so far is for log resistive sensors. These are pretty common: photocells, bend/flex sensor, force sensors. My example right now is a laser harp using $3 laser pointers and $0.50 photocells. I’ll probably do an example with a bend-sensor glove or tapping a force sensor next. I’m also, of course, hoping people decide to buy the kits and come up with neat new interfaces.

I’ll release the Analog/Digital I/O board next, which will be much simpler, in a sense…but will allow 5 buttons/switches and 6 analog inputs, such as distance sensors and linear potentiometers.

More importantly, I need to hack on the windows python code because the windows MIDI subsystem seems quite slow in comparison to even a 3 year old iMac!

Thanks to EYEBEAM Openlab for supporting this project as part of my fellowship!

    Couldn’t you port the pokey code over to a Python module written in C?

    ladyada; can i suggest you use MidiShare on Windows, there is a python lib for it .. as well as libMidiShare.a, too ..

  3. I will definately try it out. Right now I’m using pyPortMIDI and it works -great- under MacOS X! But then I tried it under windows and its a nightmare…
