Strobe Trigger

Home » Strobes » Strobe Trigger

This is where the real magic of the circuit is. Two versions of the circuit are provided below. The first one is a simple 555 IC driving one Strobe Light Circuit. This will be expanded with a 4017 IC driving one to ten of the Strobe Light Circuits. Both ideas come from Don’s Xenon page, slightly adapted. The second circuit will be added at a later time.
