Just a quick reminder that the project is not dead (and also a very tiny update) :D

Regarding the Tindie restock, I'm sorry for the seemingly endless delays. The boards are currently in production and I'm expecting them to be in stock again ready for shipping by early to mid January.

To keep you interested and as a sort of small additional teaser, here is a comparison between my "old" scintillator with only a single SiPM that I used for all spectra up to this day and a brand-new 1x1" crystal with the 2x2 SiPM array:

As you can see, the spectrum is a lot cleaner in total, the range is larger and the energy resolution is a lot better too. Keep in mind however, that this version costs at least around 100$ more than the "simpler" version, due to the added SiPMs and the larger, 4-layer array PCB.

The larger scintillator comes with some additional benefits such as greater efficiency and therefore also higher count rate. You don't need one as large as this, though. 18x30mm is also a great size already pretty capable.
