Hi, I am trying to modify some Andoer speed flashes to decrease the recycle time.
The circuit (see photo) is pretty simple. The flash is not adjustable (no brightness settings) and uses a 330V 110 micro farad capacitor (runs on 2 AA batteries and uses a transformer to boost to 330V). My problem is that it takes about 6 seconds for the capacitor to recharge between flashes, which is much too slow. So what can I do to get the capacitor to charge more quickly?
I tried using a slightly smaller capacitor (330V 85 micro farad) hoping that would at least shave a little time off, but it made no noticeable difference.
Somebody suggested that maybe a different transformer would speed things up. Could that be the bottleneck?
Related to this, it is unclear to me how adjustable flashes control the output of the capacitor (or do they actually control the input?) Is there a way that I could, for example, get a 330V 1100 micro farad capacitor and get it to only dump 1/10th of its charge each time the flash fires, that way I could fire it multiple times before it needed to recharge. In an ideal universe, could this be adjustable? Ultimately, cost, size, and level of skill/knowleedge required are my big limiters.
Thanks for the help
