OK, Made the changes and got the trigger part working, Thanks schmitt trigger
I have added a battery source (4 x AA) to power the trigger circuit, I then tought about it and decided to make it power the flash as well, making it portable.
Is there any reason I should not do this? for example will the batterys get drained fast.
The power section is to be internal now, with a standard ICE conector to couple the flash to the mains. Little worried about the weight of the head but keeps everything together neat and tidy.
Also I have spent about 4 hours trying to add a neon lamp to the capacitors, to come on when fully charged, the problem I keep getting is the lamps come on, then start to drain the capacitors, if you don't fire the flash quick enough there would not be enough energy stored to power the Xenon's.
Also earthing, I don't understand basic principles of safe and effective earthing, is what I have done safe earthing?
Again if anyone can point out any odvious flaws I would be very gratefull, I am starting to put this together today.
