How to take the piezoelectric crystal igniter from a lighter for use in something like a spud gun. Also, I solve the mystery of how the piezoelectric igniter circuit works in the lighter to produce the spark to light the gas and produce a flame. To do this I use my digital multimeter to look for continuity and resistance and I test the piezoelectric crystal using my oscilloscope, getting 320 volts on the scope screen.

Also watch how to get a piezoelectric igniter form a BBQ igniter/sparker:
