While playing with my Flipper Zero, I realised that the IR radiation that it reads does not have to be emitted by another electronic device! It can be a random analog IR ‘signal’ from a flame! Since Flipper can record raw IR data without interpreting it, there you go, a True Random Number Generator (TRNG)! I wrote a script that automates data collection and processing, here’s a github link. It outputs your freshly generated true random number sequence into a file.
Hi! Thanks for your attention to my little project. I agree, a FAP would be great (if only I had a bit more time and energy to work on it :P) It was just a proof of concept, built with a shell script and a few Linux tools.
