engstad/AstroCamMy hobby project is to create a camera suitable for astronomy pictures. Here you can follow my work. It is slow going, since I don't have much time to allocate for this. So don't expect too many updates.
AstroCam is an open-source printed circuit board by engstad, from the engstad/AstroCam repository on GitHub. It is a 2-layer board of 161.3 × 91.4 mm with 112 parts on 99 nets, routed with 644 tracks and 49 vias.
It is built around the LMZ10500SE, SN74LV4T125PW and LT3042, with the LV5609LP-E, MIC5355-SGYMME and RT9069-C0GB among its other parts. Its parts include 63 capacitors, 22 resistors, 14 ICs, 5 connectors and 4 inductors.

For now I have been focusing on three things:
So far, only V0.2 of the ADDI breakout board has been produced and I'm in the process of testing it:
And it works!
So, that means that I'll start working on the camera parts next.

Device for quantitative analyze energy spectra of gamma-ray sources. Allows to study what radioactive isotopes in what quantities are present in measured sample.
It measures 161.3 × 91.4 mm and has 2 copper layers, 1.6 mm thick.
112 parts, built around the LMZ10500SE, SN74LV4T125PW, LT3042 and LV5609LP-E. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
From the engstad/AstroCam repository on GitHub, at the commit this page was made from: the board is pcb/AstroCam.kicad_pcb and its schematic pcb/AstroCam.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask engstad before reusing the design.
