Christmas came a little early: The guys over at TDRM are extending their monitoring network and ran a small scale PiGI - Raspberry Pi Geiger-Müller Interface production batch with a little surplus, in the hope to find more people, who would like to get a pre-assembled, ready-to-fly module for themselves.
It's been quite a while since anything was moving here because I got sick and was down for more than 3 weeks and directly after that it was time to begin the move out of the flat that I occupied for the last decade in order to clean out the rest of all the stuff I've gathered over the years and which doesn't belong onto the Apollo-NG cargo manifest. This will be the last stepping stone to finally be able to sustain myself on the road with what I have on board.
Geiger counters are basically just devices which enable us to measure ionizing radiation. In the context of human activity we have to deal with “natural” radiation sources and “artificial” ones. Some of the materials emitting ionizing radiation are used for medicinal purposes (Radiation-Therapy), as an additive in paint and even in smoke-detectors but the majority of it is used to create electricity in nuclear power plants and to stockpile thermonuclear weapons of mass destruction (well, except …
At this point, 12 PiGI - Raspberry Pi Geiger-Müller Interface nodes are in active deployment at TDRM, helping to monitor the environment independently and so far reliably. Additional 12 nodes are on the current roadmap. That is a great success story and just in the spirit of the idea, development and open-source model of it.

Nordrunner produced and shared PiGI - Raspberry Pi Geiger-Müller Interface PCBs on pcbs.io, which are now available for everyone. If you haven't had a chance to get PCBs from fehlfarbe or shipping from Germany wasn't an option for you, you can check it out on <https://pcbs.io/share/r1Dq6>.
In the last couple of days there hasn't been much change in the numbers of the market analysis. Based on the latest numbers, it would make sense to produce a volume of 100 PiGI's as a mini series which will be the basis of the coming crowdfunding campaign.
Check it out on github: <https://github.com/apollo-ng/PiGI> Overview pyGI Server The pyGi server component is implemented in python and uses the RPi.GPIO python library to take care of handling the interrupts, generated by the impulses coming from the PiGI.
