Hardware Random Number Generator


Generating truly random numbers is surprisingly difficult to do! This project creates a serial stream output of random numbers by using the noise produced by a reverse-biased semiconductor junction in a small signal transistor. The PICAXE-08M2 is perfect for this application because of the onboard 10 bit ADC and the intrinsic serial port communication. Better yet, by programming with Picaxe BASIC the random bit-sized output can be processed into any desired form... such as numbers, letters, encryption keys and passwords.
