Okay. I've been getting a lot of request on were to buy lasers. So, how 'bout I tell you how to make one
. Of course you can always look up a fancy tutorial,
but when that fails, you have no one to complain to.To be honest, I don't think you will find a tutorial as simple as this. This is the easiest way, not necessary the cheapest, but easiest. (Unless you want to buy like 20 diods, heat sinks, and modules, this is the easiest, cheapest)
So it's very simple, and cheap
every thing you will need will be listed below....
ToolsSoldering Iron (Best quality, cheapest I could find)
Vise (cheapest I could find)
SOLDER:http://www.amazon.com/American-Terminal-AT-31604-Solder-Ounces/dp/B00030AP48/ref=sr_1_1?ie=UTF8&s=hi&qid=1278663283&sr=8-1OPTIONALBlock Of wood preferably 2x4
Now this won't be actually building a laser from scratch, but modifying it, which is the next best thing.
No this isn't pot modding, which is terrible, this is real modding, legal, and a lot better/ more professional.
The reason you want to do this is because:1.You live in the United states, and it's illegal to get strong lasers imported.
2.It's 10x cheaper.
you can save like hundreds of bucks, because this will be the same quality lasers, as
these
PartsLaser pen (This laser is bascially a laser parts, bundle, Alot of parts in one, all you have to do is disassemble it)

http://www.dealextreme.com/details.dx/sku.26891~r.93098389SUB-TOTAL COST$80.89If you already have a vise, and a soldering iron (Alot of people do)
TOTAL COST:$56.91That's not bad for something that would cost around $700 (Not potmodded)
TUTORIALSTEP1-pointer DisassemblyIf you do have a wooden block, drill a 1/2 hole in it (One that will fit the laser)
And start by putting the block of wood onto the vise, and your laser into the block of wood
AFTER GENTLY, wiggle the laser, until the module comes out
Take the button and set it aside, do not lose it!
Take the foam spring protector and the silver cap off of the old module, and screw the silver cap onto the new module.
STEP-2 module modsDe-solder the lead wires that come with the new 200 mW module
De-solder the spring off the old module
Put the spring on the new module:
STEP 3 laser reassemblyPut the button back into the laser pointer, and then align the module's switch with the button.
Put the module and pointer top in a vise and press them together,
do NOT over tighten.
Put a rag in the vise so you don't smash the pointer with metal on metal contact.
Put the batteries back in , and your ready to go.
This took me like 45 minutes to write, and I'm too lazy to add pictures right now.
