If you mean with Daedal's driver the answer is no because it needs 6 volts.

hi Daedal, what are the chances the LD will burn out? (connected directly with 2xAA batteries)? cuz so far i've burnt out 4 pioneers 16X A09XLA and a SONY 18X AW-G170A DVD burners. I saw the video clip on instructable by kipkay, he was the video creator, according to his video, he just connected his LG 16X GSA-H10N burner LD directly to the AA batteries, and it worked, can you explain why this worked? could you please make a list of the working and non-working models of the LDs? almost giving up on this project.... :'(

your help is appreciated

It only needed to work for long enough to make the movie, chances are his batteries were well used before they were used to power the laser. New ones would no doubt fry the LD.

Yes, this is very true...lol. Also it would depend on the type of AA's one is using. Using Nimh, it might last awhile. Using alkaline, it might go poof instantly, and using lithiums it probably would go poof instantly. It depends on the diode. Many of us here will tell you that running a diode connected directly to batteries is a very bad idea. Daedal's circuit is really the safest way for the price to protect the diode. At the bare minimum, a resistor and capacitor will help a great deal, but still not as good as Daedal's circuit.

thank you rog8811 and Gazoo, thanks for clearing out my doubts, if i had known a diode driver was needed to protect the LD, i wouldn't have wasted 100 bucks so far on this project, i am pretty sure there are lots people like me, who just can't figure it out why this isn't working, cuz the video looked so easy to build your own burning laser. If you lookup youtube, you can find lots clips on 'building your own burning lasers', i saw quite few ones they just did it like the way kipkay does, direct connection to the batteries, and it worked and looked cool, but again maybe just like you said, it only last for time when they shot the video, after that who knows what happend?

you're prolly referring to my video in which it's a direct hook up to the diode. it is pretty simple to do but of course you do run the risk of blowing out the diode.

Do I understand correctly that Daedal's circuit won't work with 2 AA's nor fit into a mini-mag?
Is there a good mini-mag solution for not frying these LD's by directly connecting to the battery?
Links appreciated. :)

no;

as ive said before: "friends don't let friends use minimag" [smiley=thumbsup.gif]

LOL!
Sad that some of the "popular" videos suggest the mini-mag.
I'll have to convince my partners in crime to use another solution.

If you're willing to hold of a couple of weeks at the most, I should be publishing an new guide that uses 2xAA/AAA or ONE CR123 battery ;)

I know I've been promising that a lot lately, but I just got done with both of my GB's and I'm only waiting on things to come in the mail at this point. So I will order the parts and make it pretty soon :)

Wit this circuit you could probably try and stuff things into a smaller flashlight. Although, you would need some excellent soldering skills as these are going to be smaller components, more wires.

Hold a couple of weeks? :'(
I'm ready to light something up! ;D
Sounds like I need to invest in a few more of those diodes for the next project.
We need a warning on these forums about the addictive nature of DIY lighting.

HAHAHAHA... I agree.

I did actually order the parts for that new circuit... along with a few microcontrollers and the such. This should be ready pretty soon... I think 2 weeks is a good deadline for it ;)

Okay, so what kind of batteries should I use?

Also, how do I know which pin to snap off of the diode?

Thanks.

hey daedal, even though I won't use this design, what is the best temperature limit?

I have an IR thermometer so I want to see what I should keep the temperature under.
