The basic premise of Randonautica—that your brain can influence a random-number generator—comes from controversial research conducted at Princeton beginning in 1979.

The app, which you can see in action the video below, is essentially a random number generator — assigning passengers to right or left lanes at airport security.

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.

It’s quantum, it’s chaotic, it makes for a great source for a random number generator, and there are already dozens of prototype circuits around the Internet.

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.
