Case for cheap DIY Geiger counter kit (available from aliexpress and others) with arduino and misc modules. Was a fun little project.
If you have a UV sensitive tube like mine I recommend using some kapton tape over the grill - blocks UV completely and seems to still let beta through reasonably well.
Insert slide switch first, then screw the Geiger board into place with some standoffs. Screw/jam the pushbutton in place, then attach the rest of the hardware with generous amounts of hotsnot glue - for that extra professional look..
The arduino sketch I'm running is a remix of Majek's nice code (link in my code comments) with added support for bluetooth + misc hacks/spaghetti, menu toggles and and options.
Code available here:https://github.com/noianet/arduino/blob/master/Geiger_Counter_simple_model_NGMC_V1_LCD/Geiger_Counter_simple_model_NGMC_V1_LCD.ino
Runs ~8hrs with bluetooth logging enabled and LCD backlight disabled on the ancient "1100mAh" Nokia battery I found in the junk bin and hacked into place - not too bad for code not optimized for powersaving and that (cheap) power hungry bluetooth module I used.
