The method used to generate the digits, a pair of 555 timers sending pulses through linear-feedback shift registers, would at best be considered pseudo-random.

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!

Hardware Scientists have created a random number generator that's truly random—and no, that's not an easy thing to do at all News By Jess Kinghorn published April 16, 2025 ...

A quantum random-number generator has been developed that uses classical cryptography to certify that its output was produced by a quantum process.

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.

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