Geiger Counter with Arduino and LCD
If you ever needed a Geiger Counter but couldn't find one, why not build it yourself? Geiger Counter is a very simple device but having in mind that it requires very high voltages for operation it might get tricky to interface it to a microcontroller and even have it operating on batteries.
Here is a Geiger Counter project that is hand-held, operates on batteries, has LCD display for visual and piezo beeper for audible particle detection notification. It uses Arduino for digital processing and for the detecting part - SSBM-20 GM tube is used. Anyone trying to build this device should bare in mind that it uses high voltages (around 500V) that are generated with a simple boost converter with NE555.
I also found an interesting video introduction to a Geiger Counter device so make sure you don't miss it.
