CCD Entropy Generator

This device collects entropy by detecting alpha radiation coming off of a piece of Americium-241. A sample of Americium-241 is placed directly on a CCD sensor and the blips that are detected on the 2D sensor are linearized to obtain a random value in some range. The display shows the 2D position of the detected blip as well as some other stats.

The device is built around a raspberry pi and all of the image processing code is written in python. A rudimentary front end was also build that lets the user interact with the device via touch.
