I was somewhat surprised to find a metal detector app...



Does it work, well it's andriod ;-)



The one I downloaded does, at least for magnetic materials.



As I thought you needed an externalm coil.



Depends if your droid has the magnetic sensor or not.



Yes - it works on a Galaxy S2.



Can't help thinking that with appropriate Bluetooth devices these phones

could be harnessed to do all sorts of things. And certainly that seems

to be happening in the medical world with some blood testing devices at

least in development.

I'm not sure a phone can test blood..... I know lots of things are happening in the medical world quite a few of my students do that, but the phone is only the output device it's not really used for actual testing.

You could do blood/breathe alcohol level, but somehow the phones go to have the relivant cirucitry. I suprised that aren;'t used for measuring speed too,rather than rely on a cars speedo, but I get the impression the errors might be too large.
