This is my hacked front light for my bike. It's an ATtiny45 AVT 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 below.

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 the CTM xxxxx-workshops series: one-bit music 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.
Simple one-bit synthesizer based on the ATmega8 chip.

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.
The workshop (6-hours short) was divided into 3 parts: first some theory about microcontrollers, AVR programmers and coding in C. Then we used Arduino to prototype some simple synths (bit-bang and PWM techniques). And last we took the Arduino code and burned it onto a standalone ATmega8L chip and built minimal circuits (some buttons, battery, chip, speaker).
If you want to try to do sound synthesis with the Arduino, you might want to check out the files in 1bitmusic_arduino.zip below. This file also includes code for my little synth called monijonsyn.
2007 I ported some old Java code from 2001 to SuperCollider. The class (RedConstruct) is available below though note that it's fairly useless. Also available as a MaxMSP external called f0.construct.

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 spent some time porting over 22 of the 35 examples that come with the nice graphical programming environment NodeBox to SuperCollider. (NodeBox is based on Python and specialises in generative graphics.)
If one compares the code for these examples, I think it is obvious how capable SuperCollider is for 2D graphics. It's just as simple as NodeBox and Processing!
Well, some more advanced features are missing at the moment - like reading back paths, image manipulation, bindings to CoreImage, PDF export etc, but simple interactive 2D and animation SuperCollider can handle.
All the ported code lives here...
