how visible was the beam of the laser at 350mW? i would love to have a red laser that had a visible bearm like that!

dayyyyuuummm... 600mA?! is that a senkat diode?

i wasnt disagreeing with you Kenom, just adding more possibilities and adding scientific explainations ::). if he got a defective or maybe micro-scratched lens inside the diode itself, it will create that interference. its like putting a stick into a stream and watching the water flow around it...

cyclonite, i have the same matches (small white plastic can with pop top) and i lit one of them with my laser. i sharpied the tip and it went up almost instantly. did you have it focused correctly?

eh, so you have a nazi diode..... as long as it will burn things, no biggie ;D

About this picture... The dots and waves of bright and dark spots on this image, those are not necessairly dust spots. they are actually the waves of light creating disturbances with each other. what happens is there is some sort of impurity in the glass itself on the laser diode, be it a...

yeah, thats what i did my build with. i cant imagine not having thee ribbed ring to focus with...

hehee, thats a burn

i just so happen to be right in the flight path for Newport News/Williamsburg Intl. Airport. heh. airport is less than a mile from my house.

heh, im aware.... and im working on the video problem

Also, a neat little video.... http://www.zippyvideos.com/6548463627333766/dscn1302/

the thing i was so frusterated with is all the confusion between what people were saying...then that got me confused. Then i would see a design, start collecting parts for it and read further into the thread and it would be nay sayed, haha. oh well. got it done with 2x10ohm resistors like Kenom...

it works!!! Muahahaa.... *pinky to lips* yup, and right away from the womb it was burning and blasting photons. :) Thanks for all the help ! ~DJ

can your please take some pictures of your internal setup? im more of a visual learner. I have it soldered together but im having trouble putting it all in the housing. Thanks!

I HAVE LASER! well, not visible. I used the IR diode instead. Got it to burn into a micro SD-SD converter. I focused it under my table out of sight with my webcam. i reworked the schematics some to make it really compact. came out well. I have some tweaking to do with the fitting issue, but i...

yeah... it was definately a dumb move... i guess im getting a GB diode now. Im done harvesting.... I did confirm the IR was the one that was coming on. I pointed it at my eye and my eye started to bleed. just kidding on that last bit.... but i used my Computer Camera and saw a nice bright...

ok... im not sure which one i should use... i soldered 2 AA batteries up and put some test leads on... i have one where i hook it to typical positive and negative and i dont see anything, then i hook the other one up and i see a dim red light... at 3V, shouldnt it lase? or am i missing somthing?

gah.... which diode is the red one? how can i tell? one had a glass lens glued to it... is that the IR one?

i have my DVD diode being extracted right now... Anyone know if 2 10 ohm resistors in series is good enough to restrict the current for the Dorcy?
