No Geiger counters? https://github.com/jareklupinski/passing-particles https://github.com/jareklupinski/passing-particles lmk if you want a >real< source of random-ness ;P
- ncmncm 5y agoRadioactivity is not a better source of random noise than shot noise in semiconductors, or resistive noise from current in non-superconducting materials. It is not better than black-body noise from a radio receiver, or pixel noise in an image sensor, or the low 20 bits of your processor cycle counter, sampled when a keystroke or packet comes in. What does matter is whether you have the entropy you need when you need it. Your favorite radioactive source might not have that. At device power-on, you might need entropy before the camera or radio receiver is initialized. That is when you need to consider carefully where to get some entropy, and how much of it you need right then. Maybe you can arrange to have saved enough over from when you were last powered up.
