Here I run through the excellent theory of operations document that Jez provided as part of the kit. It is very comprehensive and illustrates some nice features of the circuit like the differentiator to remove negative spikes on a trigger signal and a simple AND gate using two diodes and a mosfet. Part 3 will be working out the math that goes into component value selections for the 555's.
