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.

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

Technology Engineering Here’s how to generate a truly random number with quantum physics Andrew Paul Jun 12, 2025 2:01 PM EDT ...

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.

The world’s first practical quantum random number generator (QRNG) will reportedly overcome weaknesses of current encryption, revolutionizing internet security.

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.

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.
