Hardware design to create a true-random number generator. See https://hackaday.io/project/21054-true-random-number-generator for details.
The EAGLE files are incomplete and unchecked. I have hand-edited the symbols and footprints based on miscellaneous EAGLE data that I have found spread around. It is not to be trusted yet! It needs checking. Also the electrical design has not been prototyped or simulated.
