Making a laster pointer from a Module

[Vamp]

Im thinking about building my first basic green laser pointer.

I've decieded on the module being this 200mW 532nm Green Laser Module (200mW 532nm Green Laser Module (3V 11.9mm) (Green Lasers Category) - $114.95 : Gadgets Direct - Australias Largest Gadget Store with Free Shipping on Everything) but what other parts do I need for this?

Thanks!

You'll need a host to hold it and a 3V battery but other than that the module has everything it needs to lase.

maybe get a module with a spring on the end and use THIS well thats what im gunna do anyway. but because yours is 200mw u might want to get something with heatsinking so idk.
if you go with that host all you need is a cr2 battery and ur good to go. but just to let you know ive heard that the front lens which makes it waterproof does make the laser a little less powerfull, but not by much

goodluck

you can expect a 10% loss because of waterproofing lenses...
but yeah, alll you need is that, a hosts, ( new wish pen hosts or that one^^^ work well) and batteries... you have a soldering iron?

oh yeeh i just read that sometimes the waterproofing is dodgy aswell and leaks so id go with the pen host HERE i think rayfoss sells both of these hosts aswell but i like odicforce so thats why i post their website. also you may want to limit duty cycles if you want 200mw laser to make sure it doesnt overheat

Will two AAA batteries work?

Or will I need something like this?

18650 Rechargeable Lithium LiFePO4 Battery 2 Pack (1350mAh) (Batteries Category) - $27.95 : Gadgets Direct - Australias Largest Gadget Store with Free Shipping on Everything

I already have one of these to use as a host:

Wait a little longer, Save alot of money.
I have brought this module from this site before

Also if you want focus ability - http://odicforce.com/shop/article_O...er-Modules.html?shop_param=cid=24&aid=OFL302&
but this involves removing the glued in lens.

Thanks for the cheaper site for this module but can anyone answer my Q about the batteries?
Thanks

yep 2xAAA will work perfectly.
