Abstract

An electronic ignition circuit for use with a fuse head may include a microcontroller, a firing capacitor operably coupled to the fuse head, a voltage measuring circuit operably coupled to the microcontroller and configured to measure a voltage across the firing capacitor, and a switch operably coupled to the microcontroller, the switch being provided in series with the fuse head and a ground. The microcontroller may be configured control the voltage measuring circuit to measure a first voltage across the firing capacitor, actuate the switch to discharge the firing capacitor across the fuse head in response to a firing signal, control the voltage measuring circuit to measure a second voltage across the firing capacitor, and output a shot detection signal based on the first voltage and the second voltage.
