Download

Here you can download the circuit diagram, the source files and the memory dump of the current software version V1.2. The circuit diagram is the same as the one shown on the Circuit Description page, but this time it's in PDF format.
The software is supplied as an Intel HEX file and must be programmed into a 27C256 EPROM.

Have fun with this project, but I can't emphasize it often enough:

Keep it safe and be careful with high voltages!.

Release notes:

V1.2 (1 February 2017)
