Random Numbers

Random numbers are numbers that occur in a sequence such that two conditions are met: (1) the values are uniformly distributed over a defined interval or set, and (2) it is impossible to predict future values based on past or present ones. Random numbers are important in statistical analysis and probability theory.

Analog 4-bit random number generator

“As previously reported, I’m on a slow track research project into randomness. Having explored the concept of random bits and built some experimental random electronics, I’m still progressing in my question to understand how randomness can be exploited …

Chernobyl Dice

“The Chernobyl Dice is a quantum random number generator [0] that uses nuclear decays from a weakly radioactive sample as a source of entropy. It consists of four primary components: - An Arduino Nano microcontroller - A Geiger counter - Six uranium glass …

BubblesRNG

“BubblesRNG: A True Random Number Generator Using Air Bubbles As An Unconventional Source Of Entropy. This is the project I submitted for the final year while reading for a B.Sc. in Computing and Information Systems with the University of …

Project  cVert

cVert

“cVert is the result of an idea I’ve been kicking around for years, and took a few months of work to bring to fruition. The idea was to use a Geiger counter as a true random number generator to …

Infinite Noise TRNG (True Random Number Generator)

“The Infinite Noise TRNG is a USB key hardware true random number generator. It uses what I call a “Modular Entropy Multiplier” architecture (previously Infinite Noise Multiplier or FireBug). Besides being simple, low-cost, and fast, it is much easier to …

Random LED Dots: Entropy Library for Moah Speed with Less Gimcrackery

“A discussion over the Squidwrench Operating Table about injecting entropy into VMs before / during their boot sequence reminded me that I wanted to try the Entropy library with my 8×8 RGB LED matrix. The original version trundled along with …

Hardware Random Bit Generator

“The article appearing below was one of my recent posts to the sci.crypt newsgroup. These are some notes about building a hardware random bit generator. Johnny von Neumann once said that anybody who contemplates arithmetic methods for the generation …

Random Signal Generator

Today we will build two circuits that, with the help of two integrated chips and some components, allow us to generate random results. Both circuits use a CD4011 IC that implements 4 NAND ports with buffer and a CD4017 IC …
