I followed the progress of the RP2350 Hacking Challenge (the first edition; Raspberry Pi later launched a second edition), and when the deadline arrived there were multiple solutions. Some were more interesting than others, in my opinion. One I found particularly interesting was Aedan Cullen’s, which relies on glitching the OTP power source.
