Flipper Zero + a lighter = true random number generator! (www.youtube.com)

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.

Hi, I liked the ideas, so I made the FAP 🙂

Hey @RyeJVlan@lemmy.dbzer0.com , thanks for your interest! I'll take a look at your solution once I have a chance to! Very glad that you found my little PoC inspiring 🤩🙏

Hi @RyeJVlan@lemmy.dbzer0.com , are you planning to publish your FAP on https://lab.flipper.net/apps ?

[–] RyeJVlan@lemmy.dbzer0.com 2 points 9 months ago

Yeah I do plan on publishing it hopefully soon. Just trying to wrap up a feature for generating phrases from a word list and some general code cleanup before I do.

FAP is published 🙂

Just dropped v2.0. Lots of overall improvements and optimizations. Also, it now includes Bluetooth HID for exporting a generated string.
