Default DIY 445nm pointer

Hi, this is my first post and I'm quite noobish about lasers. I started with a 200mw green from DX and now I want to build my own >1W 445nm pointer. I just need some advise and help choosing the parts needed. Would these parts be enough for my build?
XJA-140 Diode (*** = laser surplus parts)
405nm/445nm Driver
5.6mm Aixiz module
405~445nm AR coated lens

Thank you in advance.

You missed heatsink and battery. Both can cost significant amounts of money. And that is the very minimum. Generally you will also need host, and switch .. both usually come in form of LED flashlight.

Thank you for all the quick replies. As I already said I only own one laser pointer which I bought assembled from DX. I thought the aixiz module was a host and also act like a heatsink. And doesn't the driver already have a switch? Thank you.

As for the battery I plan on using one 18650, or would 2xCR2 be better?

You can not put 2 CR2 in series because the driver accepts only 4.2V maximum.

You have to think that when you buy the host, what type of battery accepts, and if the battery voltage is good to your driver.

Oops forgot flashlight hosts can't do parallel batteries. And about the aixiz module, is it suppose to go inside a host? Where does the heatsink go? Sorry for all the dumb questions.

Check this:

SolarForce L2P 445 Maxed - The Blue Blaster...

There are more threads like this around. You'll get some idea.

The more I read about DIY pointers the more confusing it gets. How much would it cost to order an already assembled pointer with a A140 diode on a 18650 host, inc shipping to Portugal?
