Most of the photographers prefer flashes with battery. Such pulsed lamps serial production get a charge from the battery “Molniya” or the inverter low voltage dry cells in the high. But “Lightning” is rarely for sale and is kept short. Batteries do not save enough — the kit is barely enough to shoot two narrow films. So we have Willy-nilly “attached” to a wall outlet.
From this predicament I found a way, using alkaline Nickel-cadmium rechargeable battery nonspillable brand 2НКП-20. Its advantages: ease of use, durability and ability to recharge. To power the flash needs to collect the voltage Converter (see schematic diagram). Transformer T1 is wound on the core SH1 5X15. The winding of I contains 18+18 turns of wire sew-1 of 0.41, II — 12+14 turns of PEV-1 is 0.2 and III winding is 300 turns of PEV-1 0,1. Resistor — MLT-1 or VS-1, the capacitor oxide CAM or K50-6.
