A violet beam is more visible at night than red. Blu-Ray is not blue, it is far from it. True blue is 473nM.

does anyone make ones closer to true blue that aren't a billion dollars? lol
i think i'll go the way of blu ray sometime in the future. maybe if enough people petition dx for empty dilda cases cause i think they are nice (er than a flashlight)

how about them 3.6v cr2's? i cant find anything on them... does dx have any?

erm... no.. unless you work for a laser company like dragonlasers and you can get the hookups. Or if you found a way to order all the parts including the rare crystals for a cheap price.. or if someone in the buy sell trade section is selling their blue for a good price, there is really no way to get a cheap blue.

oh well, maybe in 5 years it'll be cheap haha.
dealextreme has 3.6v batteries but they are either cr123a or the number is the size, what size is cr2's on dx?

I'm in vacation in Florida. Your throat gets wet from just breathing! And you get all sticky. Other than that, it is awesome. There are also geckos everywhere... i caught one yesterday, and it bit me :-/

There's a few more somewhere out there. Most red laser tutorials can also be used to build blu rays, all thats changed is the diode and current.

I keep reading about using parts from dvd burners, is this necessary. This will be my first laser. I just wanna make something that is bright and possibly burn stuff.

Pretty much any diode here is from something. Nothing wrong with that :D
