After doing this build I was left with the head of the Trustfire df009. I also had a Fenix extension tube (for tk61 / 75 / 76 etc…). I tried to modify the Fenix battery carrier a long time ago and made a mess of it so ordered up an astrolux battery carrier. The carrier is set up 2s2p and I would’ve just used the xhp-70 already in the df009 but I didn’t have a 2s e-switch driver. So the xhp-70 got swapped out for a sst-90v2 and the carrier will need rewiring. First up , to the lathe 
Update 11/4/20
I made up a centering ring but kinda failed. It needed to be slightly thicker for better focus but more importantly when I opened the hole in the reflector I didn’t open it quite enough and twisted the glass off the sbt-90 :person_facepalming:
Anywhoo I moved on to making the tail.
Test fit. I used an SRK bezel I had left over from another build.
I flipped it in the chuck a few times and unfortunately marred the surface.
So I spent some time trying to download code to get a nice light show from the adafruit trinket and neopixels. I managed to get a lava lamp to work and also this simple mixed colour to work. What I wanted was a rotating rainbow but it’s beyond my comprehension of code and I didn’t manage to find a code that worked on the trinket. Still it looks sexy :heart_eyes:
It’s not quite finished yet. I still need to touch up a few things. Like fit an 18650 protection circuit board to the trinket (not that I think it really needs it because it’s not going to be left on). Once I’ve decided on what program to run on the trinket I’ll secure everything in the tail and peel off the protective tape I have on the mirror and glass.
The tail operates independently of the head. It’s a twisty. Screw on to turn on, unscrew a crack to turn off. I used a convex mirror at the base of the infinity mirror which gives the effect of a parabolic shape rather than a tube shape. I’m pretty happy with how it looks so I’m keen to finish it.
