Need input on host ideas

[Philipnzw]

Hey folks, a newbie here. Need someone to help check if my ideas are valid.

I have 2 host build ideas and I need someone to "fact check" if i have got things right.

First build is a small 10440 cell host. It is a 12mm*87mm stainless steel host. The main problem i have with this host is of course it's tiny size. As it most probably could not even fit a standard 12mm laser module in it. To make this work, i think i could find a way to sand down the heatsink to 11mm or lesser (until it fits). However given the extremely small size i think any laser built with this host will have a terribly short duty cycle in order to keep the lifespan of the laser longer. I want to try to jam a 200mW 650nm laser into this host, do you guys think it's okay?

For better thermals, i think i would just get a generic 12mm screw-on heatsink to dissipate the waste heat. However that's gonna be very ugly but i'm fine with that.

The flashlight host.


The tiny driver pill.


Besides that, can someone help me check if this is similar enough to a generic c6 host? Can i use a 17mm driver or should i just bypass the stock driver and use a rectangular shaped driver?

I've also found a 14500 sized version of the same host, but obviously they are a tad smaller.

18650 version:

The body dimensions are as shown above (in the 3rd row)

The only pic they provide that shows the insides.

14500 version:

This one is shorter and also smaller in diameter.

Contact point has no spring.

So as stated in my Intro post, i am still relatively new to lasers and learning a bit more day by day (still have to find a way to get heatsinks locally). Therefore i felt like i could use some input on my ideas before i start.

PS: Are there any prominent/active members from Malaysia/Singapore that i could get in touch with?
Sure seems like there aren't many laser hobbyist in Malaysia

Hi bud,i can help you a bit .hahah
about 10440 host,i think i can make a small heatsink to accept diode and driver,but it ís hard when you build laser,module 200mw 650nm you show me have 20mm driver,so not enough space ,so you need a smaller driver,flex or same
and about 14500 host,it can't accept 17mm driver
Pm to my FB anytime bros
