PiGI - A Raspberry Pi Geiger-Mueller Interface

The PiGI is built as a ready-to-go drop-in module for the Raspberry Pi to transform it into a versatile geiger counter to measure/monitor radioactivity. It will generate the required high voltage the counting tubes need to operate and it will safely invert the counting impulses to a falling edge, detectable by a GPIO Pin on the PI. But it's also designed in such a universal way in order to be very hackable. Basically it can be connected to any processing system that can detect falling edges like:

• Arduino
• ATMega
• PIC
• Other embedded Linux ARM/MIPS systems with GPIO Inputs (GNUBLIN, Netus G20 etc.)

Specifications

• 40x43mm board
• Very low energy consumption (<2mA @ 0.09uSv/h local dose rate)
• Cathode counting
• Low BOM count / small footprint
• Very cheap design: Prototype costs per board -> EUR15 / High Volume Production < 10 EUR
• Dual stackable for low/high dosis counting with 2 tubes
• Open-Source Hardware/Software
