Hi,
Im trying to make electronic midi drums. Ive got my electronics sorted: A piezo disk into a peak detector op-amp circuit then connected to a pic which sends midi out with its USART. Thats all working fine:
Piezo triggering
Midi activity
My problem lies in that i want to house them in biscuit tins. A big roses tin for a snare, and two other smaller tins for toms. I glued (epoxy) the disks to the undersides of the lids and connected them to a phono socket on the side of the tin. They just dont work right. They work periodically (about 3 in 10 hits). Its so frustrating, i thought this would be the easy part!
The tin where its glued is like those jars or bottles of food where you press the lid and it pops if its already been opened. This doesnt seem good for the disk also as one of the leads fell off after a few presses.
I want it to trigger really easily and reliably so i can drum fast with just my hands
Has anyone used these piezo disks? How did you mount them onto stuff?
The guy who i got the idea from used sheet metal but i thought biscuit tins would be better cos its thinner?
Ive attached my input circuit.
