Step 1

Here is the schematic for the power and trigger control board. You can view it in Scheme-It. Q1 is a N-Channel MOSFET to protect against an inverted polarity power supply. I used a LM7806 and a LM7808 instead of a single LM7505 to give a faster switching time. U1..U4 is a 7 channel hex inverter. J6 is a BNC connector. J3 should be a female header, others are male.
