flyback hysteresis
Ok so I've been working on this flash unit for a while on and off (not so much free time)
The idea is this. car battery, camera trap, BIG HUGE FLASH that can recharge rapidly but not drain the car battery (so it should be efficient)
Also speedy (this IS speedy with a discharge of around 150 microseconds)
It's almost ready for field testing but it is sort of weak (56 joules). This is a limitation of the radio shack bulb, not my design. Right now the flash is set off with a pushbutton that is connected to 600 volts. I don't think my camera will approve =D
ALSO the cap bank will be replaceable with a much smaller and lower inductance module for ~10-20 microsecond flashes (for hummingbirds and the like)
