Developer with nickname “6Fg8” from XDA-Developers.com made an interesting proof-of-concept application that basically turns the HTC HD2 into a metal detector. How you ask? Apparently, it uses the HD2’s built-in compass to “detect metal nearby by the deviation of the earth’s magnetic field included by the metal.” Sounds like a mumbo-jumbo but apparently it works… I guess.
Here’s what they say how to use the app:
Place your device flat on a surface. After starting the app, the gauge should show zero. If it doesn’t, take your device and write a couple of “eights” in the air (this is to get rid of magnetism which might get stuck in the sensors). Then use a pair of scissor or something the like and move it slowly to the right side of your device. At a distance of approx. 5 cm. the gauge should start to move. Take your device and move it with its right side near metals, and see if the gauge shows values.
Please note that this is the pre-alpha 0.0.0.1 release, so it will definitely need some improvements. Still, you may want to give it a try – you can download metal detector for your HD2 from here.
