Feel free to share your theories on the best random number generator designs below, or send your best builds straight to the tipsline. Randomly, of course!

For that you’ll need a true random number generator (RNG), and this open-source hardware RNG uses one of the better methods we’ve seen.

That means that even if some enemy understands everything about how the random number generator works, they still can’t predict the outcome.

Professor Jooyoung Lee stated, "POSDRBG is a new deterministic random bit generator that improves both random number generation speed and security, making it applicable from small IoT devices to ...

Using a single, chip-scale laser, scientists have managed to generate streams of completely random numbers at about 100 times the speed of the fastest random-numbers generator systems that are ...

A new laser’s chaotic light beam lets the device generate multiple number sequences at once, similar to throwing multiple dice at a time.

A new random number generator that uses a micro laser developed by researchers at NTU Singapore is a hundred times faster than computer-based systems.
