-Mcu (attiny, picaxe, etc)
-Momentary push button to select pulse width
-fixed value pulse delay e.g., 500us
-led indicator for selected pulse width

Hardwired timers to force a max ON period and a minimum OFF period on the MOSFET in case the MCU goes bonkers.

Adjustable current limit.

I suggest using watchdog timer then it doesnt matter, the system will simply reset. If you have a reset counter in software with an auto shut off after say 20 attempts.
