Another strobe that many people have in their shop is an automotive timing
light. You can wind a simple coil of a few dozen turns and put it in the
trigger clip. Then, any convenient signal source such as an audio signal
generator can be used to produce the timing signals.

good luck,

PS: thanks for remembering the harmonics thread, Robert. (:it was fun

I remember thinking(back then) that I wanted to take a real good look
a the engine installation on the new plane for harmonic reactions.

I even asked around and found someone who have an old variable speed
disco strobe for the job.

But the engine wasn't ready to run back then, and I forgot about it.
Until now.

Thanks.

Radio Shack has a strobe for about $20. It's cheap, and won't even give
an epiletic a fit, but it has variable timing and does flash. You just
won't be able to use it in direct sunlight. Wait 'till evening or find
an old barn?
