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!

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.

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 ...
