Open Gamma Detector

I’m really glad to see how it’s getting easier to distribute work like this, from easy pcb ordering to 1-click bom ordering.

I’m also interested in the gradual adoption of and categorisation of the properties for using photodiode based scintillation detecting methods. Much less fragile than a glass tube, lower voltages, etc.

Nice to hear. I'm the creator of Kitspace.org and I've spent a lot of time making the 1-click ordering work. It's an open source platform by the way: https://github.com/kitspace

I'm far from an expert on this subject and am not sure if it fits the definition of "scintillation", but here's another particle detector that uses photodiodes:

- electron-detector: https://kitspace.org/boards/github.com/ozel/diy_particle_det...

- alpha-spectrometer: https://kitspace.org/boards/github.com/ozel/diy_particle_det...

Very nice! Sorry for my inexperience but how would you proceed as a beginner to build one of these projects?

I understand you can buy the components from Digikey but you have to print a PCB with those components, right?

So it's the PCB printer that should have access to the components, no?

I'd be interested in how the calibration works, you need known samples for the energy and not all of them are easy to get.

This is the great thing about wider exploration of these technologies, the calibration data (modulo the individual per chip variability) can be crowdsourced across the combinations of samples and detectors by the entire user base.

I don't have the electronics chops to build one of these, but I'd certainly buy one.
