I attended the second DIY geiger counter workshop on August 22. This was taught by Kalin, and involved soldering three parts of a homemade gieger counter:
- Freakduino motherboard (right) - this is basically an arduino board with a wireless radio interface. It provides the power to the NetRAD and keeps track of the rate of radioactive events.
- NetRAD shield (left) - an interface to power the tube and keep a TCP/IP connection for communication.
