here's a screencast of some of the examples coming with the redUniverse quark.
some are just simple processes while others are a little bit more 'intelligent' (boids mainly).

trying to finish this custom controller before leaving for japan. almost ready now - just the casing left to do. it has 5 rotary encoders (endless) with as many push buttons, 2 softpots and 3 touch sensors (capacitive). it is built using the absolutely brilliant avr-usb from obdev and shows up like a standard HID devices. small, lightweight and just one cable (usb). plus it is very cheap to build - see parts list. the biggest cost is the encoders.

this is my hacked front light for my bike. it's a tiny45 avr microcontroller that i programmed to play the complete 14min drum part in ravel's bolero. the reason i picked bolero was that it's a fairly well known rhythm and that it's very repetitive (= don't require much memory).
firmware attached.

i was so fed up with only listening to music in headphones, so with the help of my dad i built a pair of SQ-50L. they sound really great. full and rich sound. i have a sonic impact t-amp gen2 to drive them.

this is version 2 of a minimal and cheap one-bit synthesizer i developed for this workshop. basically i just changed the hardware and took out one of the potentiometers and lowered the oscillator to 1mhz. now it sounds a lot different and more chaotic.

finally found some time to build a tiny synth based on a design by SGMK (mechatronicart.ch). so simple and it sounds so good! evil little thing. i did some modifications: basically one more audio channel with different pots and caps and 2 switches for the ldr.

as part of the xxxxx-workshops series at this year's club transmediale, i was asked to do a day on one bit music. this is a very silly way to produce music - basically flipping pins on/off with no amplitude control! but i liked the challenge and for me limitations like these are needed to get anything done at all. thanks to anke, martin and derek for organising.
attached are the slides, arduino code and schematics we used that day.

ported some old java code (also a max external - f0.construct) to supercollider. it's fairly useless.

now i've also worked on porting some examples from processing to supercollider. this was a bit trickier than porting over code from nodebox. many fundamental processing features aren't implemented in supercollider - video, 3d, opengl etc.

the code lives here...

i'll upload more later on.
