Is this some kind of joke?

All I see is a cheap regulator IC, some wire, and a resistor... not even a dollar worth of parts.

god giving noob the option to go up to 4.5a on the 140 diodes what a bad idea
my laser broke... whine whine bitch bitch.
theres a reason why drivers should not go over 2a 2.2a max for the current moment.
shit that much for just one 1$ for a regulator i got over 200 plus lm317s for oh yeah nothin!

Yeah, sure, sounds great, I'll pick up two $0.10 components for $20 shipped from a guy who, judging by his grammar and spelling, spent most of his school days on a toilet.

It's horrible how people don't have something better to do in their spare time.

Incredible deal!

:paypal:

Holy cow dude, at least put some effort into soldering the thing together. I think he's trying to pull a kipkay, where he shows you his awesome laser on youtube and then gives you the links to buy overpriced crap.

I must say this is a brilliant soldering but what are the components.. what are the components and how much mA's does it produce..
