WOW ! it has been a long time since I was in this thread , I was was last here about 1200 Posts ago !!
any way I still have been playing and here is my Latest creation
I have been watchingthe eveolution of the Highintensity LED's over the last couple years, I have done some experimenting , and I came up with one that has been working quite well .
First I got a Cree LED P4 a (

2nd I got a Current regulator (

and a Lens
http://www.dealextreme.com/details.dx/sku.4626 , other parts that I needed , but had a 4 AA batter y Holder (
www.bgmicro.com ) some speaker witer , an old Pentium 90 with Heat sink , the slot cover from a PC a SPST switch , 2 old Coke Caps ( with the points redeamed ) and some velcro.
First I attached the wires from the out put ofthe current regulator to the LED star and Connected some speaker wire to the Regulators input
then I took the Pentium with heat sink , ad removed the Fan and the Pentium . I took the heat Sink and marked the 4 holes for the lens to attach to. and 2 holes for the mounting bracket .
Next I put the LED star on the heat sink, and then the lens, the Lens has 4 post to screw into , so I screwed the 4 screws in holding the lens and LED in place.
Next I attached the PC slot cover bracket to teh Heat sink. Then Using a Hot Melt glue I attached one of the Coke caps
I cut a Small Notch in the coke cap on the top ( should have put it on the side or bottom ) then I put the current regulator and wire into the cap,
The I took the other Coke cap amd sealed them together with the hot melt making it ( hopefully ) water proof.
Now I took the other end of the Speaker wire ( about 4 feet ) and SOldered it to the leads of the 4 AA battery pack. this particulat pack has a wire running across the back, so I Cut it and soldered the switch in place there , then Used the hot met to attach it.
Next IPut velcro on Both my Helmet and the Bottom ofthe PC bracket , and I also Bent the PC bracket to give it a curve to match my Helmet
Mounted ,
and I have been using this to commute , and I have also used it as my Sole light in the woods , It is no Match for an HID , but this cost me a total of Less than $25.
Still to Come
a) a Handle bar mounted one
b) a 2 -3 -4 Emmiter light
