Fast LED flashing 1.5V
The Fast LED flashing circuit. that apply to AA Cell 1.5V. By add resistor 1K size between pin 1 and 8 pin of IC number LM3909. It will rate winking expansion 3 again times. When build capacitor 330uF sizes suit 1 pin and 2 adaptation pin modify by the tow electronic part outside. It make way for choose for resistor outside equal to 3K,6K and 9K. Other detail , see in the circuit.

Photo Flash in Camera with battery 1.5V
This the Photo Flash circuit in cheapness Camera. By this circuit be one charges with a single button press. Then have the convenience goes up and have high volt generator circuit from 1.5V AA cell. It is composes transistor and the equipment is other. Be the circuit produces tall frequency drives coil transformer subsequently submit high volt at diode be dc current give the capacitor 160uF also. When we press shutter as a result will have the light photo flash come out with. The detail is other , read more source: http://www.members.shaw.ca/novotill/PhotoFlashes1v5/index.htm
