I have been at the #powerglitching workshop today at #hackadaeurope ! Pretty advanced topic, I feared I was not up to the topic, but the teacher was reasonably good at explaining and prepared a very convenient testbench in the form of a (very cool) PCB with two #MCU: one is the target (the one to glitch) and the other is the one that controls the power supply to the first one via a #mosfet.
