Hi

Update for you, tonight I hooked up my detector to the Kemo preamp and then into a LM386 based audio amp.

Above you can see the set up.

It needs to be cleaned up which I suspect will reduce the buzzing.

As you can hear on the attached sound file the detector is very sensitive indeed!

It responds to just moving my hand near it, I would say that anything generating a AM radio/EM field would be detected by this.

Upgrades include a more powerful audio amp and some way to spin some powerful magnets near to the detector.

Thoughts?
