I got a lathe 4 days ago and have been learning how to use it.
I figured "what better way then to make a heatsink?" ^_^
Took a few attempts to get something I liked but this is what I came up with:
The first attempt was supposed to go under the glass of the flashlight host and fit exactly like a p60 drop in (waterproof FTW!!!) but The wire I have ordered from flaminpyro hasn't showed yet and the wire I do have was going to break the leads of the diode off... Need more room
Back to the drawing board.
This was the second attempt, remove the glass stick the heatsink out in front
I screwed up and made the relief for the board a little too big plus I got some chatter in a couple of places and made the part sticking out the front a little too narrow.
My third attempt I decided not to bother with the "negative terminal spring" and just made it to fit perfectly just as the threads bottom out. I also made the front part a bit longer because the 2nd one looked a bit stubby :crackup:
The driver I used is easily obtained, producing 1.495mA steady (tested on a dummy load for 2 minutes), and very inexpensive (~$3) but I don't condone a step 1. step 2. step 3. approach to building a potentially dangerous laser. If a couple of the veterans think its a good idea, I'll edit the info in later but it is just a little too easy to do and even someone with no idea of the capacity could build this laser.
I'm planning a build with a bigger (read "wider") heatsink in another ultrafire host (top in the next pic) and keep that one under the glass. Are the back reflections hard on the diode at 1.6W?
From the top, this is an
ultrafire SSC P7-D emitter host,
Stainless steel Cree R2,
The 445 build with the 3rd attempt heatsink completed and ready to lase,
an 18650 battery for size reference ^_^
Of course there has to be at least one beamshot with such a pretty color :na:
Hope you like my 1st build.
