yeah. I would suggest, first thing you do, is do some reading. And alot of it. Just becasue it's the cheapest 1,000mW laser you could find, you wanted it. So You need to read up on alot of stuff first before you even attempt this, and to tell you the truth, if you get it before you do read, ALOT, you will kill the diode. Which could probably be the best thing you've ever done. Being blind could not be fun, especially if you actually want to see your lasers. with which 808nm, you will not be able to.
Try a red module as bhwollen said first, and read alot about it, and understand what you are working with, and how it works. There is a reason above 5mW lasers are illegal in the US and most countrys, because if somebody who does not know what they are doing grabs one, and says oh wow, it says 1,000mW 808nm, and I think it's on but i do not know, why don't I just look straight into the laser? and boom, instant blindness.
Search the forums, and read everything. Go to the saftey section first, many many NEEDED TO BE READ threads out there!
Hope your lazing goes well for you, and hope you become addicted, and safe, like many many people, including me, have
