I'm sure there are members who do, I don't buy them pre-built, always buy the diode and then put it into a host someone else has made. Where have you been looking to find one online?
$59 dollars is very cheap, not sure what you can build for that yourself, certainly nothing that nice looking unless you can machine aluminum yourself. However, I've never seen the quality of that particular pointer myself, only photo's. Has anyone here had one of those?
But you said you wanted 3 watts, I don't think you will find a 3 watt laser for $59.00 completed.
Why do you need a 3W laser? I think it's best to start with <200mW. Anything over 1W is extremely dangerous and can blind you quicker than you can blink. Its like getting your first gun and starting off with a double barreled sawn off shotgun.
Holy shit. What distance and how that occured to you sir. Now are you good?
You didn't use safety glasses? With safety glasses are we 100% sure?
Read the thread, it was probably 5-10ft for less than a second he didn't have safety glasses on but that was "only" a 1W laser. Imagine what a 3W laser would have done.
Ok you scared me alot, I'll think much more about buying a laser with that power. But with safety glasses I would be 100% secure?
