Finally (only one year) later got around to finishing the SC01 mod, using a BLF 15DD driver shaved down. Here's some pics of the process/parts:
Blue wire on left is for the switch, blue wire on the right is to fix the trace I destroyed:
The short black wire near the top is an extra ground wire, jammed in between the SinkPAD and edge of pill:
Where the "K" was in SinkPAD was an attempt to make a spot to solder the grnd wire to. That didn't work - just could not get solder to stick to the SinkPAD at all. Think the heat is taken away so quick you can't solder to it - that's what I'm guessing:
The LED is an XM-L2 T5 5B1 (my favorite tint). With a WindyFire 14500,I measured 3.85A at the tail:
Turbo lumens: 1003 @start, 874 @30 secs, throw: 8.5 kcd (184 meters)
moon: 4 lumens, lo: 52 lumens, med: 129 lumens, hi: 394 lumens
With my custom switch software, it has 5 nice modes, click goes from moon to turbo, hold goes from turbo down to moon, long hold is strobe. Current mode locks in by 1-2 secs, so click from ON turns the light OFF. But even when locked in, a hold will decrement the mode.
This is really nice light now - great tint, great power. I wish I got this mod done sooner. No idea if anyone else out there has modded one of these like this with a piggyback driver, but if I were to go it again (which I will), I'll use a 12mm DD driver instead - fitting that 15mm shaved like that was a real PIA. I actually filed/sanded thru a trace and had to add a replacement wire. I ordered 12mm DD boards to do the SC03 with.
Both my SC01 and SC03 had died - both had stock driver problems.
Missing from the pics is some details:
- on the bare stock driver, I had to add extensions using thin copper strip (from a copper sheet) to get access to the batt + and switch connection, because the angled in BLF15DD board blocked the pads.
- I used Arctic Alumina epoxy to set the driver assembly into the pill - little was used at the base of the BLF15DD to secure it to the stock drivers, and more was used on the top edge of the switch board to secure it into the pill top (original stock setup was like that too)
- I added a ground wire (like there was originally) to be sure I got a better ground than from the mount of the stock driver (jammed the wire against the pill).
Edit 05/11: 12mm OSHPark boards arrived today. Will size one up for the SC03.
