Hello Ted,

I've been thinking about this problem and working on a design for a
capacitor discharge system to power the HEI coil for the trigger.  555
Timers are a part.  As long as the same starting point is used during each
half cycle, it doesn't matter when it is.  That is if the 555 timer input
detects voltage from a full wave rectifier going below a certain value, zero
crossing detection is not needed.

I'll have more when I build this thing and especially if it works.

Regards,

I'd suggest a very useful feature of the triggered gap will be the ability
to fire it when ever required giving the chance to do real time experiments
with BPS and the phase of each firing.

Hence my interest is a zero crossing detector and a series of monostables to
generate adjustable timing points. This use of the zero crossing detector to
time things will generate identical firing times on both the negative and
positive mains cycles too.
