Hiya Jinx,

If say a 0.6J flash is what you want, run a 5 or 6.5uf 440V polly capacitor
(the ones they use for cap start on motors) this will give you a great
little strobe.

I have built strobes with 22uF 450VDC axial capacitor, 680R 11W current
limiter, and a standard  trigger with a 4N28 opto driver.


Regards,

Kat.
