The fukushima disaster brought a new wave of radiatation and awareness towards the topic.
Some people at shackspace wanted to build a geigercounter to actually have some means of measuring radiation levels. Unfortunately that never happened.
On our New Years visit to brmlab (prague, cz) we stumbled across some radioactive ore and thus the the topic had our attention again.
The sensors were crowdfunded by tw, makefu, exco, timm, optimizr, karlo, hornig, uebner
radioactive@home is an open hardware open software project from some guys in Poland utilizing boinc to fetch the data from geiger counters all over the world.
Some soldering fun
Trying to shave off some cents we ordered SMD capacitors … lesson learned: these are marked on the positive side.
If for some reason the geiger counter ticks / led blinking is too annoying - you can change the behaviour online (iot) or press the marked hardware button. The rz team should have the necessary credentials.
The boinc client (@shackspace) runs on the nucular (nukular) (→phenylbutazone.shack 10.42.2.3) virtual machine.
