Here's my top 5 list of DIY audio art kits to keep you busy in 2010.
Open source, Arduino-based version of the monome controller interface that utilizes usb midi and open sound control. Great for controlling instruments, installations, and performances.
Peter Edwards' Drone Lab is a 4 voice analog drone synth, rhythm generator and FX processor. A great kit from one of the kings of circuit bending.
Simple but powerful kit from the Loud Objects performance group. You can easily integrate your own code to write new low-bit jams.
