Random numbers are very important to us in this computer age, being used for all sorts of security and cryptographic tasks. [Theory to Thing] recently built a device to generate random numbers ...

A random noise generator is pretty handy when working with music, and building one using a micro-controller can be pretty trivial. So it’s nice when someone comes along and builds it from a few analog ...

Random numbers are useful beasts, in particular for cryptographers who use them to generate their codes. But how best to make random numbers at useful speeds? The question is intimately linked to the ...

Fast randomness A diagram of the quantum random number generator on the photonic integrated chip. (Courtesy: Bing Bai and Yao Zheng) Smartphones could soon come equipped with a quantum-powered source ...

Random number generators in digital information systems make use of physical entropy sources such as electronic and photonic noise to add unpredictability to deterministically generated pseudo-random ...

Two years ago we featured SimplyNoise, a dead-simple white noise generator. A recent update adds in additional sounds, features, and an iOS app for white-noise naps on the go. Originally SimplyNoise ...
