Help finding remaining parts for DIY laser

[ZachThePwn]

Hey all, been awhile since I've posted! Been mainly doing photography with my lasers but decided I'd give a try into building my own. I recently purchased this diode with a pre-installed driver to get the hang of it before I buy a more expensive diode Brass 532nm 20mW Green Dot Laser Diode Module 3V-3.7V w/ Driver +Spring + Wire | eBay, and was wondering what other parts would I need? I am assuming I will need a lens but I am unsure of how I'm going to connect the batteries to it to power it, and how to get it to turn on / off with a button. I've been messing around with my soldering iron so I've got a bit of a feel for it, but really just need help finding compatible parts at this point. Thanks in advance all!

Get an AA battery holder for two AAs and put two AAs in it. Hook it up, press the button on the board. Or bypass that button and add your own switch/button between the V+ of the driver and the V+ of the battery pack... Unless you're planning on building a pointer with it?

This already has a collimating lens, no need to get one.

Yea I plan on making a pointer with it, not really going for good looks, but something I can carry around.

Have you read any of the build threads from other members? They may give you some ideas on how to proceed.

Your best bet would to put that in a typical ebay pen type pointer,
as they really are a direct replacement module for them.
You can cut the wire leads if you go that way or use them if needed if you try something another host.
Its also a case "positive" module like your other greens.
Look up some 532 Fasttech module builds for idea's..
Like diachi said, no need for a lens as its a fixed focus.
