battery ground on driver
the positive can be also used with MCU with a proper flashed Firmware to enable it
and don’t worry the board version with the outer lane to crack sometimes is fixed a long time ago
stupid fab placed the break drills too wide into the board
Alright thanks, I’ll have to open mine up when I get your board and see what I can find
Just a little work in progress…….
Noice!
Thanks, still fine tuning it a bit. I need to get another o-ring for it though, forgot to take it out before I started removing the anodizing and it has now disappeared. The glass lens rattles a bit without it. 
Picture makes it look pretty deep crenelations for what “meat” is left on that bezel. I guess it’s an illusion or there is more material than it seems to work with. Interesting!
Still a little bit left on the bezel. If you look closely to a stock bezel you can see there is two angles,the one closest to the lens is probably 1mm thick. I stopped at the top of that one.
Oh and I found the o-ring, it was on the garage floor. 
Finally finished this FW3C for the wife:
I swapped the emitters for some LH351D’s (the venerable “dogfarts” at 5000k) and added an “ice blue” AUX board from Lexel. Some hand polishing and a bit of wax to keep it a little more shiny for good measure.
Pretty!
How’s the tint and beam profile? Looking at swapping in some dogfarts I’ve got kicking around on another FW3A incoming.
I like it. It’s my idea of a perfect “neutral white”, and pretty floody. My wife is not really into flashlights (yet) but she does like this one.
FW3/Ti BUG…
Viry Narce 
I guess you could call it a hat rod
So was playing around with the bezel again, planned to polish it to a mirror shine but didn’t like how it was turning out.
Decided to take a red scotch bright pad to it for more of a brushed/machined finish. Will probably live on my FW3T and it matches better than on the FW3A imo.
The aluminum is a little lighter in color than the titanium in pics but in person it’s almost identical.
Just ordered an FW3C. Does anyone think it’s possible to form a penny into the shape of the tail button? Don’t know if it would deform too much if I could make a steel die and press a penny into the right shape. Thoughts?
Not sure if it is possible (could be), but I think it’s a cool idea.
Dang, that looks great.
I have to disagree. If I can’t get TK Special buttons, the rabbit button is a cool alternative.
Has anyone put XP-G3 s 4K 90 cri in this light yet —- I’m looking to do something different — I have all the stock flavors and then some —- I’m thinking may a variety of 4K emitters SST 4K / 351D 3.5K / XP-G3 4K
Thanks!
This ^ Would love to have a different button option.
