I ordered the 9mm module with X-drive @2.2A from DTR's site, the torch from DX (sku 191998), and machined the heatsink locally at one of the machine shops in my country. It runs off 2 Lithium Batteries.
This is the host from DX that I ordered. It's a pretty bright light on its own, but I chose it because I was looking for a 2x 18650 host, and it was the cheapest that looked like it'd have a lot of space for the heatsink and module.
It's extremely easy to take apart, and I took my vernier calipers to start drawing out the blueprint for the heatsink. The pill is removable (top right).
I just got the heatsink machined today, and also took out all the components from the driver board.
This is the heatsink up close. The guy at the machine shop told me copper would be difficult to machine, and would cost more. Also, they didn't have any stock on hand, so I'd have to order it first, and wait for it to arrive. I decided against that, and so just went with aluminium. It's still pretty big, so I'd reckon there should be a decent run time. I haven't tried running for more than a few seconds at a time though.
After soldering on the wires from the module, I screwed the pill in first before pressing the driver board in. This way, I can be sure the wires would not twist and break.
Just before I slotted in the module into the heatsink, I applied some thermal paste over the copper part to help it spread its heat better.
And this is the finished laser! Pretty neat I think.
Beamshot at night. I live in an apartment in the suburbs, so there's some light pollution, but the beam is darn solid! It's my first class 4 laser, so I'm really happy.
This is it just sitting on my desk.
I measured the power using an OPHIR head and a multimeter. It fluctuates around 2.8W, so I guess this is an average diode? The X-drive is set to 2.2A, and I measured around 1.9A at the tailcap.
My first class IV laser. Really happy about it!
And :thanks: for reading!
