[APP]metal detector - v1.0.0.0

metal Detector for HTC HD2
idea & code: 6Fg8
artwork: youmeus

supported devices
HTC HD2, nothing else!

How it works
The built-in compass uses the earth's magnetic field to calculate the deviation from magnetic north. As with every compass, if you put a piece of metal nearby, it gets deviated. Thats what i use here to detect metal.

Testing
Place your device flat on a surface. After starting the app, the gauge should show zero. If it doesnt, 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.

And if you turn your deviceupside down you can´t see the screen...

Works awesome, but need a better interface...

Cool device man! Keep on the good job...

are there already results? Can we say that this app is accurate?

I can use it very good but I need to rely on it that it shows the right values...

Um, how can this work? I thought it was a digital compass that was in the phone, not a genuine magnetic compass... Not doubting your hard work here. I just didn't think it was a genuine physical compass in either the HD2 or the iPhone.

Sorry, a bit confused.

It is a real sensor, a magneto-inductive sensor that can pick up the earths magnetic field and work out its direction of flow, and hence north. Although we think of them as 'digital compasses', they are more accurately 'electronic compasses' with no moving parts.
