This is a project that was initiated by Jonas Bers. The original version uses the same hex inverter as I used in the Thunder Honey synth. After experimenting a bit I decided to use LTC1799 oscillators instead of the 40106 hex inverter. The brain in this project is a Chinese VGA test image generator that you can buy from eBay for around $5. I’m not going to go into any technical details here, check Jonas’ blog post for how to make one yourself.
