New detector revision coming soon!

A project log for All-In-One Gamma-Ray Spectrometer

More sensitive to gamma radiation than a Geiger counter with the added bonus of telling exactly what's inside your samples!

Firstly, welcome to all the numerous newcomers to this project that came here from some of the articles released in the last couple of days! I'm glad that so many other people are interested in this kind of (arguably) pretty exotic topic :)

As you might have noticed, some parts are currently becoming Unoptanium. This includes the OPA2354 OpAmp that's used and most importantly the MicroFC-60035-SMT silicon photomultiplier itself. To try and fix these issues, I'm working hard on replacing these parts in the mean time, until they eventually get in stock again (which will probably not happen too soon unfortunately).


Like I said before, I also want to improve some other things with the new boards that I didn't consider yet with the current design. The most important parts are as follows:


The Broadcom AFBR-S4N66C013 SiPM

By the way, the Raspberry Pi Pico W was released today which is very exciting news! In the future I might use it on this detector as well, enabling wireless communication and more. However, we need to wait for enough stock and full software support.

I hope to get finished in the next couple of days, so stay tuned for more project logs!
