I thought Id put a little bit about the microphone ive been playing with to see what others are using. See if improvements can be made.
I started with a 50mm pizo mic from local electrical parts shop (maplin) £1.99, a 1/4 inch jack socket £1.99 a magnet from ebay, and a bit off an old latch for a handle.
The Second Mic I made has turned out better. Instead of glueing the mic straight on to the magnet, I glued a 48mm rubber O ring on first, then glued the mic onto the O ring.
I also ran the cables up through the middle of the magnet, instead of around the outside.
This second version is working much better.
