Description
The Open geiger project aims to give access to cheap geiger counters for the masses. This is an attempt at making such a cheap geiger counter - using PIN diodes and following the design of the 'Stuttgarter Geigerle'- in a smaller size form. In this repository are made available the production files for the realisation of such a cheap pocket geiger counter:
- Schematic
- Kicad files
- Gerber files
- 3D printed case (TBD)

Questions
How big is the Geiger PCB?
It measures 49.5 × 42.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Geiger use?
44 parts, built around the AD8666ARZ, LM358, HEF4027BT and BPW34. 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 Geiger KiCad files?
From the SyrianSpock/open-geiger-counter repository on GitHub, at the commit this page was made from: the board is kicad/geiger.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Geiger design in my own project?
Its repository states no licence, so its author keeps all rights: ask SyrianSpock before reusing the design.
