The pulser is simply a CMOS 555 chip. Timing is done by splitting the
current flow from pin 3 to pin 2 with diodes and running them through
separate pots. This allows individual control over the on and off time.
The MOSFETs for driving the coil should be rated for 6A 500V at a
minimum. A small heatsink will be required. Bipolar transistors can be
used too if the current output from the 555 is boosted.
You can use two coils in opposite polarity to double the voltage. Be
sure to ground each coil's case if it isn't already. Stray voltage
collecting on it could zap something.
