14 unsuccessful replies saying much the same thing does not make an interesting thread. Time for the answer. Don't forget the title of the thread.

Sure, just post your pic TDU, any time you like it...

It was a electric guitar piezo pickup, shielded with braid at the end of coax cable.
I picked this up for repair from guy at school.

It is made of flexible polymer instead crystal, and produces faint low-frequency output when flexed. I's output is very low in amplitude compared to 'normal' piezo speakers but it does work nicely with included preamplifier.

Haha, that's ironic. I've installed one of those piezo guitar pickups before, and I didn't recognise it. :S

Anyway better let TDU have his thread back wink

You hiding inside a rusty metal drum while 2 kg of steel wool combusts around you after being ignited by a 16kJ capacitor.
