This Kit builds the circuit to trigger a high voltage xenon flashtube using a 12V DC input from a power supply. The flash rate can be varied between 1 and 2 flashes per second using an onboard potentiometer. Component changes can move the flash rate range faster or slower. The Kit is constructed on a single -sided printed circuit board (PCB). Protel Autotrax and Schematic were used to design the board. PCB size: 3 1/2"x1 3/4"
