[Noisebridge-discuss] radiations sensors- radioactive parts

[Michael Shiloh]

Just like robots, people are more dangerous than the technology.

Hey, I have a bunch of old smoke detectors also. Didn't know what I was 
saving them for until now. If anyone wants them, for this or other 
experiments, let me know.

Never mind that they were invented 105 years ago! (This is a very scary attempt to limit information by controlling one's ability to analyze one's own environment!)
