Upon a request of someone I have made a device that measures the backround radiation and transmits the measured values via USB to a PC or a Raspberry Pi. It will then be used to make a graph of the doserates and / or CPM.
The unit is pretty much only a derivated type of my homemade standard arduino geiger counter / dosemeter without display, buttons, charge controller and battery.
The photos were made without the lid on the case obviously.
