Some interesting things I found on May 28th, 2008:
# CrackleBook – A cracklebox project from Worth Ekik.
I strongly recommend building this if you like noisy toys. The touch-pad interface is fun, and a nice change from the more traditional knob or key methods. As far as musicality goes, it’s not great. However, it is capable of some very interesting ambient textures such as white and pink noise. It even has some Theremin-like capabilities (see the video for me waving my hand over the pads). It’s pretty unpredictable, but if you can find the 709 chip, this is a great box to experiment with.
# Hybrid Scrapyard workshop – Hybrid Scrapyard is an extended version of The Scrapyard Challenge workshops. Participants build simple electronic projects (both with digital and analog inputs) out of found or discarded “junk” (old electronics, clothing, furniture, outdated computer equipment, appliances, turntables, monitors, gadgets, etc..).
# iPod/MP3 Player Bicycle Speaker – A simple passive speaker for your bicycle using the parts you have lying around. Loud enough to hear on quiet roads. A person with very basic soldering skills should be able to do this; doesn't require any advanced electronics knowhow.
# BalvenAmp – DIY tube amp. It's not a very good speaker, so there's a lot of low-end distortion, but at low volumes the treble is actually quite clear.
