This is my second handheld, I mostly do labby stuff. What do you think?

Diode: M140 module with X-Drive & 405-G-2 lens from DTR
Heatsink: intel cpu (cut down the fins)
Host: $15 flashlight from ACE hardware

No action shots yet- don't my glasses with me :scowl:

That sure is different but with that many fins it should cool like a beast.
How did you cut down the fins, did you spin it on a lathe?

Haha yes thank you for putting it nicely. Its not the best looking but it was cheap and stays cool. I used a dremel with a cutting disk, then a bench grinder to round it out, and a hand file for smoothing it all. Actually turned out a lot better than I thought it would.

You know, that's pretty cool! I like it, it is unique. I would like to see some pics of the insides, see it apart you know? I imagine that diode will stay plenty cool in there :)

I like it! I am planning on throwing together a Maglite with this kind of sink. +rep for creativity.

Sorry if that sounded rude but it is so different and that is neat. It reminds me of a mace or for some odd reason, hair clippers. It's like I'm waiting for the front end to spin :D

+REP for ingenuity and spending the time to try and make it really nice. Some of us really appreciate the do it yourself stuff like this. I have lots of sinks I've thought of using but only one round one with a fan in it. Haven't decided yet what to use it for but I think I would like to keep the fan active when I finally mess with it.
Take a look at some of the links in my sig as you would likely appreciate them.

Here is it disassembled.

Wasn't rude at all! Instead of having a fan just spin the heatsink :crackup:

Pman- Awesome work! I love the DIY type projects

I'm actually thinking of doing away with the fins and receding the sink back into the housing. The diameter of the solid part is just about perfect. 35mm diameter should be fine, right? I would like to have long duty cycles.

Looks awesome to me! I love the exposed, radial fins. Reminds me of a 1920s radial aircraft engine.

I see you used a zoomie flashlight as a host. Any issues locking down the front, zoomable head on that? I have two zoomie lights that are essentially hosts for whatever now, thought about making them into lasers.

What did the heatsink look like before you modded it? Did you have to drill the hole in the center for the module to fit? Press fit module or is there a set screw?

+1 for an awesome unique build!

I'm still trying to figure out a better way to lock down the zoom head. So far I've just wrapped some electrical tape around the body to make it a tight fit until I find a better way. Maybe drill and tap a set screw? I drilled the hole for the heatsink. Used a 5/32 bit, and press fit the module. I used a little file in the hole until it felt right. This is what it looked like (except with alum. core):

Oh ok, it was one of those newer core i series coolers.. gotcha. Nice work.

For the zooming head, yeah, I think a set screw would be fine. Drill the hole in the outer, zooming section, and drill just enough below in the host body to make an indent but not go through the metal; then apply set screw with some blue locktite.
