Should be in the description that its NOT 9V. The aiming-laser runs on 9V. The energy-storage is charged from 15V (10 AA-batteries)
Thanks laserbee: Was hard to get such nice pics. I have taken about 200 maybe more...
I added a pic showing the guts. Very early stadium of construction...forgot to make another one at the end of assembly before I put the housing on.
^ you don't need to switch the tank-cap block, only the trigger, like in normal flash units.
Probably, he use a microswitch .... can try to guess, if it resemble like the one i made years ago, he's using an oscillator for charge the bank, the bank is connected fixed to the lamp, and then have a little capacitor closed on a HV trigger coil for the fire electrode, and maybe a digital or bar graph voltmeter for check when the charge of the cap bank is at the right level ..... just wondering, i don't have his schematic
Edit: just for the fun (and, before you ask, no, i'm not him )
