Ultrafire C3 445nm laser

I bought this host from Tmart hoping that it would have a boost driver that could be used with our 445nm diodes. Unfortunately the driver only put out around 350mA.

So I got out my AK-007 boost driver from DX (these are older ones that are >1A, the new ones no longer output that much)

Firstly, I got myself a nice blank PCB.

Then I soldered some silicone wire leads onto it.

Then I grabbed my AK-007 driver. This was a two tier driver of which i removed the top PCB to make it 1 mode. There was also a resistor located right below that top capacitor. I removed it and bridged the gap. This driver now outputs 1.4A

Attach the AK-007 driver to the blank PCB

Attach output leads to the AK-007 driver.

These stupid LED stars are so hard to get out, so i just busted the LED off the star.

I put the AK-007 driver inside the pill and fed the output leads through the holes.

This is my 445nm diode inside a machined aluminum module. Pressing a diode into a zinc coated brass aixiz module can't work that good... (look up the thermal conductivity of zinc and brass)

Snatch up my pretty little heat sink I made for this host.

Put the module inside the heat sink....man, that module is starting to look rough.

Then I soldered the output leads onto the diode.

I also soldered the blank PCB in place so it can't fall out (solder at top)

Turning my fingers into C clamps, hold the heat sink and pill together, and spin the head. This will ensure the pill gets screwed in without spinning the heat sink and twisting up wires.

Screw the flashlight back together and you've got a tiny little beast of a laser.

Like a miniature Aurora C6, and just as strong!

My camera doesn't take very good beam shot. This is in a fully lit room.

I saw Qumefox put a green module in one of these a while back and really liked the look of the host. Then one day I was browsing a flashlight site HK Equipment(I think) and saw it so I ordered one up. This is another host that I ordered many months ago and just got around to building it.

Anyway this host has a really sold feel. It is heaver than I thought it would be. The host walls are pretty thick compared to a lot of hosts. The mass of aluminum in this host gives it great heat dispersion capabilities.

The look is pretty sweet. It has an aggressive stainless steel retaining ring on the top, has a large unique shaped head with intentions, fins around the mid section and the rubber grips that not only look good but add great functionality when trying to turn the unit on and off one handed.

This host was sent to Flaminpyro to be mated up with a heatsink. He did a great job with keeping the look of the host with the heatsink protruding slightly out the front. And the sink is like a suction cup going into the body. There is a lot of metal on metal surface area with this sink which really does a good job moving heat into the host body.

Also of note and a personal highlight for me he made a copper plate for the top of the pill to mount the flexdrives on. This makes it a pretty straight forward build a little tight but did not require further modifications to adequately sink the drivers.

I am going to run through the build guide as I have shown similar builds many times but I do want to hightlight the driver driver sink.

Allrigt so to run through this here is how the host breaks down. There is the host body, heatsink, head, tailcap and copper driver heatsink.

I like this one a lot. It has a uniquely aggressive look and great capability to disperse heat. I also would like to thank Jeff for the sweet job on the diode and driver heatsink.
