After lurking here for a year and a half, I finally have something to show.
I built a couple of Scar-clones last year with a Maxflex and 3x XRE. These lights were so much fun to plan and build, I thought I'd try again.
This time with a MC 33.2 and a smaller housing. I was inspired by OD Texas' microlights, but this is somewhat bigger.
There has been a lot of discussions concerning the importance of thermal pathways, so I decided to make it as simple as possible, with the pcb mounted directly on the heatsink. Furthermore it should be possible to make with a hacksaw, assorted files and a Dremel. I got an old heatsink at work, and started hacking away..
Here is the preliminary result. I thought it would be cool to make the front of the light of plywood, a material not often seen in this forum. Unfortunately the wall thicknesses are too small for strength. It does look cool with the straylight making the plywood almost translucent though.
As inline switches are expensive, I have done without one for now. The momentary switch for modes is supposed to be a remote switch for gun-mounted flashlights from DealExtreme. I have the switch, but can't seem to find it, so I guess the light is closer to a prototype at present.
The optics are the wide version, as the narrow was sold out from Lux-rc. It may still work as a helmet light, as it's quite bright. I hope to back this up with beam shots this week.
