Hi found your forum when goggling about laser diodes and dvd burner lasers.

It's been informative. So I thought I'd join. Still looking for comparisons on open vs closed diodes though.

I was under the impression that closed was better but have found mention to use open.
I already burnt out one open diode by using 2 AA batteries without a current limiter. Will be making one while I wait for another diode.
 





Well, make sure you use a driver next time, or all your diodes will go the same way :) Welcome to the forum! ;) Generally open cans can be pushed harder, but are much more delicate.
 
welcome to the forum mate you will find everyone here is very friendly and helpful
 
Well, since the thread has already been hijacked once I can do so again with good conscience.  :P

Was going to make an account and introduce myself, but noticed I had already made one on Mars 25th  :o

And now for the introduction part, I guess. From sweden, 18 years old, currently reading technology with focus on computers in what would be "upper secondary school" according to an online translator. I heard about this forum via the product forums on DealExtreme. I started reading, found the thread about making a laser from a DVD diode. We just happened to have DVD burner that wouldn't burn, so I was happy for a little whiel ^^. Until I fried the diode by connecting it directly to a battery :'( After this I read doing so might kill your diode. Anyway I've been lurking here about maybe a week reading and learning. Today I ordered the DX True 30 mW green laser, which will be my first "real" laser (if it gets through customs, that is :S)

Oh, if anyone is wondering about my user name, it's the swedish name of the bug in my avatar. The english name for it is "pine weevil" according to Wikipedia. There is a story behind this nickname involving a pun the way I blow my nose. But that's a story for later ;)
 
I'm from sweden too! [smiley=beer.gif]
Welcome!
 
Nice, more swedes is always good ^^

By the way, do you have any experience with swedish customs and lasers? Was looking around on tullverket.se but couldn't find any info :-/ That page is a friggin' jungle...
 
My laser was caught, I think at Arlanda. It was my nova laser and had to pay big $$$.
DX will label the packages like a "LED flashlight" or something like that and the customs hopefully won't bother, that's all I know.
 
Ah. I feel sorry for you :-/ But I hope mine gets through ^^'

Anyway, I'm off to bed now. Have a three hour long essay writing tomorrow, so I need to be rested :S
 
Well, I got the laser now and I'm happy with it :). I wish you good luck!
