Below is a list of projects I contrubute to or I'm interested in:
Midish -
a MIDI sequencer with shell-like interface (for Linux & OpenBSD)
Sndio -
the mid-layer
of the OpenBSD
audio sub-system.
OpenBSD -
one of the best development platforms I've ever seen.
I'm involved in the audio and midi support, drivers
for the VIA/ICE "Envy" audio interfaces and
USB audio-class devices.
Programmer for Microship 16F84 (or alike) for OpenBSD.
The schematics and the software are here:
