I built a timer using an atmega328's timer0 driving a lowside fet to sink 12v from the coil, with a button trigger and a turn/push user interface for the LCD. This implementation times 10-2200mS to sub microsecond repeatability. The air valve is rated to 100psi/6bar but leaks slightly at 3/4 that so I need to find a better one.
