Circuit Bent Modified Vtech Video Painter

In the later spring and early summer of 2006, I began getting into homebrew circuit design and fabrication. I had success in building the TI99 audio reactivity mods but needed the same sort of effect in a smaller package for the like of the Video Painter toys. I basically stripped down the filter bank to a single lowpass and let the unfiltered audio trigger the scanline bends via a 4066. The Lowpass signal triggers a 4029 counter which then opens and closes different switches on the remainging three 4066 gates.
