Do you need to solder spring to driver to work all together ?

How do you check output current ? I need to set this up to 1,8A, i have this driver

What is lenght of this heatsink ? I set mine at 15mm, probably too long. Do you use original S2+ brass driver "holder" ?

Unfortunately, I needed to delete my comment - when i printed out longer "bolt" to check if thread will fit, at the end of this bolt i cant turn it at all. I wanted to make prototype model of threaded bolt, to check If this thread is same like I printed out. If it will be the same as this in...

I mean, this thread which i screw in brass driver "holder", I dont know what type of threadd is this. I know only it it trapezoid thread, but size?... I dont know. Something between M22x1 and M22x1,5. My idea is to make on lathe something like retaining ring to hold heatsing in place.

Nice, do you know thread size in S2+ ? This in head of S2+. I can figured out, its not M22x1,5.. It is something between M22x1 and x1,5.

Right now i tested couple projects of heatsinks for Convoy S2+ (printed on 3d printer) and have performed the individual project to make heatsink in aluminium - for testing - and looks like this: Right now, Im waiting for all parts to build this up. I have S2+ flashlight, and based on this i...

What is good yellow laser diode ? If this "model" will work perfect, my next must have laser pointer is yellow color 😁

I find out that couplings for stepper motors are good idea for heatsings. ID: 12mm, OD: 20mm, and with locking screws. I need to check this options too. 😁

I ordered 17mm diameter driver from him, which fits perfect in S2+ brass driver "pill" :ROFLMAO: i do not remember name of it... I just figured out now, that i can just solder aluminium tube (or just glue) to brass driver pill outside of the host, and them just screw all in. I promise that I...

I wanted to use Convoy S2+ host. I have this flashlight and measured that heatsink need to be OD:21mm, so i found aluminium tube 21x12mm, and need to be cut 15mm long(max lenght, because longer heatsink will block battery tube to be screwed in max lenght). Only one problem will be wires, i need...

I will make heatsink myself. If you have this diodes, can you send to me a link for your driver ?

Yes, but every buck drivers which i found, they are 5A+ on output..

This diode will not work at 3,7-4,2V range in this situation ? (for ex. 3,7-4,2V 1,8A) I found good single mode driver which runs 1,75A (I post it above your reply) with anti-reverse polarity protection

In my opinion, i found probably best driver for me, but with one problem - output current is 1,75A, but "my" laser diode PLTB450B is 1.2-1.5A working rage... 1,75A will be good or too much ? And it has anti-reverse protection.

This second driver is from trusted store (Convoy)

Why size of the battery matters, if 18650 is almost the same as 2x 18350 ?

I wanted to use PLTB450B laser diode: 450nm 1.6WLaser diodePL wavelength:450nm Output Power:1.6W Spectral line width:4nm Working current:1.2-1.5A Threshold current:0.2-0.3A Package:TO-56 Operating Voltage:4.8-6.0V Operating temperature:-20 ~ +70Degrees Celsius Storage temperature:-40 ~ +...

G2 laser lens will be good if i want thinn laser beam ?

I am from Poland, so sites like Aliexpress are recommended for me. I found G2 laser lens: Will be okay in my configuration, and will fit in this housing ? Which driver will be good ? One is buck driver:
