hello everyone,
I'm from Ha Noi, Viet Nam. this is the first time i post at lpf!
sr because my E not well and my photo's quality is not good,
- i buy this diode at DTR'laser shop, thanks DTR! ^^
- I used lm350 and 2 registor ( 2R2 // 3R3 ), 1 diode 1n4007, 1 capacitor 47uF 50V.
- In here, i didn't used lm317 because if set 1,2A,lm317 very very hot ----> not good! lm317 is very hotter than lm350.
- i used glasslen three layers, if you use g-2 len,its beam is larger than glasslen 3 layers.
- this host have been made by tomsk,he is my good friend! ^^

I really like the compartment with enough room for a large driver which can be heat-sinked to the side of the host. Most hosts force you to put the driver inside the Aixiz module which doesn't lend itself to getting rid of heat very well, if at all.

A very nice build, and it's good to see a member here from Vietnam, I think you are the only one.

Exactly! Begin to problem I'm not really enough money for buy driver boost laser, i usually driver boost or buck for flashlight about 5$ which is damage for time life diode. So,i built this host for DIY driver bigger. This host can be used by 1 or 2 * 18650(lm317,350).
When it be used by 1*18650, we can remove board and used driver board flaahlight in there, very helpful! ^^
- sorry all, because my english don't well!
