Hybrid Ignition System (HIS)
The HIS is a way to get a spark-strip like unit inside of a hybrid by using only one hole. It should be noted that for multiple sparks to occur in a hybrid/pressurized environment, the gaps must be almost invisible. This method would look sweet on a clear combustion gun.
Here is the lowdown. The backbone of the unit is 1/4" sch80 PVC. The right end is tapped and a 1/8" brass plug is inserted. The left end is threaded to 1/4" MPT. The left end goes into a brass elbow, which is connected to the vertical pipe nipple. The pipe nipple goes into the tapped chamber wall. On top of the pipe nipple is a 1/4" compression fitting. Ok, back to the orange looking pieces... these are copper. The red wire going through the center is soldered inside of the 1/8" plug (right side). It runs
through the hollow tube and goes outside of the chamber. The wire is never exposed to the combustion gasses inside the chamber, but as a precaution it is
epoxied in inside of the compression fitting. The red wire goes to one stungun output wire, and the other output wire is ran to the
compression fitting. The spark jumps from the brass assembly, through the copper pieces, and to the brass plug.
