Look, [lord feistel] is doing glitching attacks on an ATMega328P! All you need is an Arduino board with its few SMD capacitors removed or a bare 328P chip, a FET, and some sort of MCU to drive it.

Of course, the star of the show is the ATmega328P microcontroller, which is mounted in a place of honor right under the OLED screen. The chip gets programmed in an Arduino Uno and then ...
