If you're building your own potato gun (potato cannon, spud gun, potato launcher or whatever you call it!) then this is the hardest part to find and assemble.

Zinc plated electrode screws with brass rod inserts (2)
Pre-wired and insulated pushbutton piezo
Electrode washers (2)
PVC piezo housing clip
PVC piezo housing

Minimum output voltage 17,000 volts
Minimum piezo element operations 33,000
Pre-wired flylead connections

With these parts all you have to do is drill two 5.5mm holes (35mm apart) in your PVC potato gun assembly and screw it in.

The length of the electrodes makes this assembly suitable for a potato gun with 100mm diameter combustion chamber. If you have a smaller pipe you just cut the brass rod to length so the electrodes come together in the middle of the pipe for the best burn.

These are the same igniters used in my fabricated potato guns and they give a nice strong spark. Piezo igniters are great too because they don't need batteries!

And the good thing with this design is that the piezo is mounted on the outside of the combustion chamber. The advantage of that is the piezo will never melt or let gas pressure escape when firing. And there's no chance of the piezo being blown out!

Installation instructions are included, with photos to make it easy to understand.
