New Feature – Geiger Counter

Here’s something new, an internet connected Geiger counter! The graph in the sidebar is updated once every 60 seconds, and can be clicked on for a larger version. Measurements are in Counts Per Minute, the graph logs 1 hour of data.

 

The counter itself is a Sparkfun Geiger counter, with the end cap removed from the tube so it can also detect alpha radiation.

Connected through USB, a Perl script queries the emulated serial port for the random 1 or 0 outputted by the counter when it detects a particle. The graph is pretty basic, but it gets the point across. Anybody who wishes to contribute to improve the graphing is welcome to comment!
