Everyone knows that the key to faster-than-light (FTL) travel is in random number generation. Advances in Bistromathics just aren’t happening fast enough so folks like Peter Allan are racing to crack the random number puzzle. It isn’t the most interesting read for those not obsessed with number theory but it is an interesting project. This garage project uses an Arduino board as the base and a small motors and an optical sensor to measure sand through a tiny hourglass.
Computers have exceptionally poor imagination. This might seem obvious but the hurdle to programmers, cryptographers and lottery officials is a very major one. Many of technologies require very truly random numbers generated often. Any patterns that start to emerge from non random systems starts to emerge over time break those systems. The amount of sand that falls at any given time creates a reading on the device. This random amount of sand specks is sent via USB to the PC system. The PC can then use or incorporate this data where it’s needed. These aren’t for sale yet but production is being considered in the near future.
