I really thought the trinket contest should use a trinket for the weekly random drawings. The first drawing used http://www.random.org/ for a random number. This week, in true Hackaday style, I knocked up a trinket random number generator in about an hour. (That includes soldering the headers on!)

I used the arduino libraries pseudo random number generator. To keep things really random, I generated the random seed from millis() (number of milliseconds since the Arduino/Trinket was powered up)
