Ignition source
The ignition source is used to ignite the flammable gasses in the chamber of combustion and hybrid cannons. The most common ignition sources include:
- Lantern sparkers
 - Piezoelectric BBQ ignitors
 - Stun guns
 - Camera flash-based ignitions
 - Flyback ignitions
 - Automotive ignition coils
 
All of these except the lantern sparker produce an electric spark, and need to be connected to some form of spark gap or spark strip.
