Survival Laser DIY C6 Host Assembly



Survival Laser Red Anodized Aluminum Heat Sink



Contact board (cheap led driver)



Aixiz adjustable current laser diode driver 80-500mA w/TTL



Red Laser Diodes ML101U29-25




CR123A batteries



All together



I started with desoldering all parts from Cheap LED driver then I pressed it into driver pill. Then I pressed Laser diode into Aixiz module. Next step was to solder very carefully laser diode pins to Aixiz driver and the final step was soldering leads from contact board to laser driver input.



Then I screwed driver pill into host assembly body.



Then I screwed next part of the host.



After that, I put laser module into red anodized heatsink and I used allen wrench to tight it for the best heat conductivity.



And almost last step was to screw top part of the host. (be very careful because driver is too big. DO NOT TIGHT IT because you risk damaging your diode)




The final step is very easy, insert batteries in.



Assembled laser :drool:



I used electrical tape to fix those two spaces, because it wasn't tight and the body was unscrewing.



Now its time to capture some beamshot :lasergun:



I hope you like this cheap and small red laser build

Very cool. Add some pictures.

I'll add some beamshots later

Err, your pictures are not showing up. Make sure they are not in a private folder or something like that.

I was able to see them, just have uploaded them on another image hosting

Now I can see the images.

Nice build and awesome pics

I have 3 C6 hosts laying around and don't have a red... I guess its time.

Awesome build and list! I have already ordered a few things off of it for my build. Some of those prices are super cheap!!!! So I hope you don't mind, yet I figured that is what This thread was for.
I did notice that you bought extra aixis lens for the build. Did you just want extra or am I missing a detail?

You will need only 1x lens, one build one lens,

I know but the listed aixis module comes with a lens. So I was just womdering if the other lens he ordered were different

oh, my bad. same lens come with aixiz module, so the build is even cheaper, I had module and lens so I didn't order them.

if your driver pill had the brass ring would it seat tighter, so you wouldn't have to tape it?

Great build, and one of the cheapest I've seen too. Good job with the photos too, I like detailed build threads. Thanks for posting that. +rep.

The pill in a C6 comes with a brass ring. I think the problem is that the AixiZ driver is a little too large for that host.

Pi R Squared is right, the driver is too large to fit into this host well, so you have to tape it

Cool thanks for the clarity

You're welcome It's nice to see that you guys like this thread
