Wondering if anybody has a schematic for the little PAL LED flashlight. The little on with a single white LED and the button where one push is LOW, second push is high, third push is blinking light. Runs on a 9V battery.
It uses an LM317, 4093, 4013 and a bunch of what look like small FETs or transistors.
I know I could buy another one for $20, but I want to fix it. LED is still good, I suspect the ICs are good as well but when I push the button the light flashes strangely.
Stupid thing has a four layer PCB and would be impossible to trace out visually. Looks like the picture:
thanks
