README
README.mdV3 version in progress. V2 version details:
xray-detector, based on SBT-11A sensor, combined with powerbank futures.
At this moment project finished. Everething works, but with several UI-bugs :)
I will fix them in future, but basically project finished.
Features:
- xray-detector on SBT-11A sensor (senses beta & gamma radiation)
- history in sievert, monthly dose, graph with last severall minutes
- beta-radiation rameasurement feature
- flashlight :-)
- powerbank
- long battery life (about half-year) without recharging
- Simple upgrade firmware - Flushing USB port can be accessed with-out unboxing

Questions
How big is the Xray v3 PCB?
It measures 80 × 111 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Xray v3 use?
215 parts, built around the ATTINY1616-MN, SN74LVC1G126DBVR-TP, INA199A3DCK and SN74LVC1T45DCK. 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.
Where can I download the Xray v3 KiCad files?
From the shm-dmitry/xray-detector repository on GitHub, at the commit this page was made from: the board is schematics/xray-v3/xray-v3.kicad_pcb and its schematic schematics/W2-PD(IP).v1.0/W2-PD(IP).v1.0.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Xray v3 design in my own project?
Its repository states no licence, so its author keeps all rights: ask shm-dmitry before reusing the design.
