Heh... i was talking with Bjorn about something like this not so long ago.

Wonder if your average phone camera sensor could be simply modified to detect radiation from nearby sources?

Most phones have a seldom used "secondary" camera which is sucky resolution, this should be easy to hack in this way.

I was thinking about modifying this type of hardware, growing cheaper and more powerful at a fast rate every year, but I never though about using them as a network like this!

seems like a great idea, but the main concerns would be things not only along the lines of battery life, but app security. Though I'm sure that if the idea became popular enough Google or Apple could help implement a little extra measures to put people at ease (like a function in the OS to call the camera in a special way rather than a normal photo form that might freak people out).

Sounds like a really bad idea, people will go insane over background radiation.

I disagree. I think that if you made the counter digital so the radiation count would show up on the screen and of course provide a seperate manual for it or something then it would be a very good way to profit off peoples fear smile

Do you honestly think people would read the manual? They'd leave their phone on their granite countertop and call 911 when they realize there is a rise above background.

There is a reason why there are warnings on lawnmowers to not stick your arm in one, and warnings on blowtorches to not point them at your eye.

My personal favorite is the warning I saw on a bag of peanuts that it may contain peanuts, duh.

Warning label: "Do not insert screwdriver into penis." !!!

Whoa! anyone who needs a warning label like this.... needs to see a shrink!

I don't even wanna know the details of the lawsuit that must have spurred that one!

Make it idiotproof and someone will make a better idiot.


Anyways, the point of the project was to make a large distributed cosmic ray detector for a telescope, and it does not necessarily have to show people the live output does it?

If it were advertised as a nuclear radiation detector, which most people would interpret as power plants, fusion, chaos, etc, then they would freak out.
But if listed as a "Cosmic Ray Detector Telescope" app, then people who do need those warning stickers on lawnmowers would not know the difference.
