Recently started new project - WF-500 4x Seoul Mod 
.
I know, there is something similar @ DX - Romisen RC-T5, but as i red mutch like "this is bad, that is not cool etc", i decided to mod my own.
It will be using 4x Seoul emitters, 4xIMS20 or 4xKhatod 20mm reflectors , will decide later witch beam i like more.
Yesterday i finished the driver board, it uses Pic12f629, has 4 modes (normal-high-strobe-low), it always starts from 1st (must use mode for 2sec). For "normal" mode it delivers to each LED 350mA using two AMC7135 chips, "low" mode also, but with PWM to get 80mA to each LED, for "high" and "strobe", leds are Mosfet - resistor driven. "High" mode is about 1-1.1A (will measure the actual current when, get assembled in flashlight).
PICTURES
Dimmensions are: 27mm diameter, 9mm height
Video of mode-switching
p.s. how do you post youtube videos "embded"? On my homepage it works but here in forum it doesn't...
