  • No problem. This was recorded by a client of mine (slightly edited with sound effects by me) , and he specified how he wanted the sequencer to operate. I built and programmed it (the circuit board) for him. The circuit board takes care of the timing, reversing of the polarity for the lens coils, as well as flashing of the bulb during the yellow phase.
