ESP32anza

The final #glitchy prototype is on the way from Shenzhen, along with an early #ESP32anza prototype and some other delights.

We had to give up the ghost on galvanic glitching in order to keep the BOM low enough to still sell it in the $20-30 range.

That is okay! We replaced the NPN+Relay circuits with N-Channel MOSFETs similar to what the Hextree Faultier uses. This works out because NAND flash bootloader glitching uses ground, and most everything out there is an active low reset.

Between that and replacing the discontinued digital pot, and many other roadblocks, it has been a long and difficult journey. We are finally approaching completion of the #glitchy project and cannot wait to make it available to you, the “valued” “customer”.
