The project is an analog Geiger counter that is capable of detecting and measuring the three forms of radiation including alpha, beta, and gamma radiation.
Using the PIC18F252 or PIC18F2525 as capture device, the project was designed to build a low cost logic analyzer while showing the display on a Windows based PC.
The device is a simple, small, and cheap frequency meter with out any hard to find components to be able to measure frequencies up to 40 MHz while having below 1% errors.
