Well, it's not really new, I've been working on it for months, but this might be my first post about it...
The original design uses the SST-90 LED, and a driver board that I designed around the LDO-10C DC-DC and a thermistor trim, based on ideas from folks over on candle power forums. If I had to do it again (and I might), I'd have a closer look at the Maxim 16384.
The reason I say original design is because that was the first plan, and I'll be continuing that design, but it's taking a while and I need a working light! So, I'm also assembling an SSC P7 based light that uses the same frame. When the SST-90 is functional, I should be able to just pop out the P7 electronics and put the SST-90 in place.
Anyway, the light head is a hacked-up Mag 2D. The battery pack is my "signature" PVC battery canister containing 3s2p 26650 4000mAH batteries. Est. run time on single charge is ~2H (I'll know more after I tune the current on the driver).
The handle is one I made over the past two days based on the design in the Airspeed Press book.
Here are some pictures of the work in progress. The electronics have yet to be installed, due to my blowing the first LED (made the incorrect assumption that my driver board was set to a lower voltage than it was), and avnet sending me the wrong part in replacement (they sent me the prototype board, not the SMD).
