Hi,
I used one of ABarnetts a-140 445nm diodes and a Chinese boost driver so it has 1 10440 battery and 1 battery spacer. I have some buck (chinese) drivers otw, the next ones I build will use 2 10440's
Here's a 1+w pen laser, it's focusable and has a 2 min duty cycle. The driver is set at 1.2 amps.
This thing can actually be held like a pen for freehand wood burning etc.
I have exactally $28 in this one
Hi,
Found a exterior lens spring for under $2, they're conical and work perfect for exterior lens springs. They are in the penlight below and come up for auction every 30 mins or so on ebay. The rest of the light is usable as a host
Hi,
Just want to add that I've been using these hosts for nubm44 builds in combination with efest 18350 batteries. Works great, still my favorite flashlight host by far
Re: My first NUBM44 build.. need advice!
My advice to you is,
Place your driver where it is easily acessed and use as little thermal adhesive as possible because it's easier to remove when needed and bonded better thermally.
