A quick tour of my Ludlum 177 based background radiation experiment build. I am going to interface a Raspberry Pi with the unit to get background radiation readings over a year including temp, humidity, and barometric pressure readings.

Geiger counter: Ludlum 177.
Geiger tube/probe: Ludlum 44-9 Alpha, beta, gamma/x-ray sensitive.
Counter IC: TI SN74LV8154 dual 16-bit counter w/3-state output.

Geiger counter is connected to the development circuits via a DB-9 serial cable.
