No known bugs at this point in time

Mounting the PZT discs is a little tricky. Tomas Ussing from Denmark suggests that normal solder will disolve the silver, and that you should use a low melting point silver solder.

Cut (with a hole punch) a 16mm circle of polyethylene plastic sheet (about 50um thick). Cut a chord across one edge. Stick sheet to negative side of PZT disc.
Connect wires to the piezo disc:
- Clean PZT with isopropanol.
- Find a soldering iron with a very small tip and set it to 290 deg C.
- Tin the PZT with a small dot of conventional multicore solder.
- Use single strand AWG30 gauge silver plated wirewrap wire.
- Tin 2mm at the ends of the wire with conventional multicore solder.
- Solder ends to PZT.
