Hi, today I built a simple scintillation counter using an 128 x 32 px OLED and a Raspberry Pi Pico with the Mini SiD board. It's very temporary just as a showcase, but you could obviously build everything much tighter without all these jumper cables. Also the scintillator was too large to put onto the PCB as you can see.

It's just a simple "device", but what more do you need for the beginning, right? The display updates every 2 seconds and displays the average number of cps that accumulated over this timespan.

Everything was, once again, programmed using the Arduino IDE. You can have a look at the sketch here on GitHub: https://github.com/Open-Gamma-Project/Mini-SiD

Cheers!
