The board design is complete, and I'm working on the firmware. There are a bunch of radiation monitors that have been deployed which log to SD cards, and they want them modified so they upload to a webservice. The idea is to program the esp8266 so it parses and reformats the data before sending it on to the webservice API.
The project is more or less functional at this point but needs tidying up. The code (and PCB designs) are all on github if anyone wants it: git@github.com:Safecast/bGeigieNano_ESP8266.git or linked in the post above.
