Just a quick update to say that I have just installed my security door magnet pickup and it sounds great! Demo hopefully coming soon!
Ok so why should this work? This is how it's designed to work: In the center is a permanent magnet, that keeps the door locked (or in some cases open) even without the power needing to be on, around this is a coil, an electro magnet but this is connected up so that when 24 volts is applied to it it cancels out the permanent one and you can open the door! Anyhow a permanent magnet surrounded by a coil is exactly what a guitar pick up is!Now the magnet is a bit too strong and the coil should have a few more turns on it but it does seem to work and work pretty darn well! Btw I have it bcz it got scrapped bcz it's fixing hole's thread is missing.
