i'll try to post the pictures up in a couple of days. my camera is with my friends.

i've manage to make the driver. it works and the beam is definately stronger. i'm using just 3ohms of resistance. making it roughly 416mA. i notice that my beam at its max focus, it produces a line instead of a dot. the lens that i'm using is a dot lens. any idea why the best focal point...

thank stuart.

yep, i did press the diode into the module. it has fit nicely on the module. the speed of the DVD-RW that i used is 20x

thanks again, greenmechanic. the video of the 510mA was pretty sweet. the lens that i am using, i'm not too sure of it myself too. i got the laser module of an electronic hardware store available locally. i removed the diode and just used the lens. as for the power source, i'm considering to...

hi jerry, thanks for your input. for the LD, i'm using an old DVD-RW burner LD, any idea what's the amount of current will produce a more sustainable diode life? i sure dont want the dead laser diode count to go up :D i managed to make the driver using a proto-board. the laser is shown, but...

hi scopeguy20, i am aware that some forum members are mentioning that you sell laser diodes for quite a good price. do you have any blue-violet laser diode for sale? do you have the needed driver for it too?

Thanks alot, Greenmechanic. since now i know the pin configuration of the pot,lm317 and diode, can i use 1 of the 0.25W 3.9 ohm resistor instead of 2 10ohm resistor in parallel? if i am using daedal's DIY driver, the battery source mentioned is 6V, which is equilvalent to 4 x AA batteries...

Hi there, this is my first time trying to build a red burning laser using the laser diode from my old DVD-RW drive. i saw kipkap's video but i know laser diode are extremely sensitive when used without a driver. i successfully extracted the diode out and manage to put it into a laser module...
