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.

    Thank you for your attention 🤩🙏. Yeah, it’s a toy version of the same principle.
