This DIY Kit based on PIC16F648A processor and includes excellent hardware and software to build small dosimeter with modern components. The kit can be used with all popular american and russian GM tubes, such as SBM20, SI29BG, SBM19, LND712, LND7317 and more. The board was intended mostly for people with previous experience in soldering SMT parts.

High voltage generated with PWM and can be adjusted from 300V up to 800V with editing eeprom byte. Conversion factor from CPM to Dose is also controlled with eeprom from 0.0001 to 0.0250

Dosimeter consume very tiny current at background that allow to use lightweight 300mAh LiPO. At background radiation it consume only 3.5mA-6.0mA when LCD backlight powered through 1K resistor. The board includes USB charge circuit for lithium battery, low drop 3.3V voltage stabilizer and negative voltage inverter for LCD contrast.    

It can be connected to computer through USB TTL dongle for our Radiation Logger software. The PIC send CPM value each 10 seconds via UART and Windows software will write csv log files on your harddrive.
