Introducing the mightyohm.com Geiger Counter kit!
Features:
100% Open Source Hardware!
An ATtiny2313 microcontroller brain that is begging to be hacked!
LED and piezo speaker alert you to detected radioactivity.
Headers for serial (9600 baud), in-circuit programming of the AVR microcontroller, and 100us pulse output (to connect the geiger counter to other stuff!)
Serial data logging! Counts per second (CPS), counts per minute (CPM), and equivalent dose are reported via the serial port once a second.
Support for several common Geiger-Müller tubes: SI-3BG, SI-1G, and SBM-20. HV supply can be adjusted from ~300-600V.
Kits!
There are currently three ordering options:
- You can buy the complete Geiger Counter kit with a tested, known good SBM-20 Geiger-Muller tube included (recommended).
- You can buy the same kit with all parts except the Geiger tube (in case you already have one).
- Or, you can purchase a bare PCB only (for experimenters).

Credits:
While this kit is uniquely mine, it was inspired by several existing DIY Geiger Counter Kits. I borrowed from several sources, most notably the HVPS is based on a design that I first saw at BroHogan‘s DIYGeigerCounter site. The original circuit appears in “Biassing [sic] G-M Tubes Isn’t So Hard” by Tom Napier in the January 2004 issue of Nuts & Volts.
