3x AAA is only 4.5Vout, where each 10440 is ~4v fully charged. Most drivers require a certain voltage to operate (called Vdrop here), as does the diode. If you add the Vdrop to the forward voltage needed by the diode (Vf) you will know what total voltage supply is needed from your batteries. The...

Hi asvestomix, There are quite a few different drivers out there, and choice is dependant on what diode you are driving, the host size, the batteries you want to use, etc. If you want to get it running today (you still need an aixiz mind you) - build your own circuit. Read this "Laser Driver -...

Hi asvestomix, What DVD burner did that diode come from? You will need to know what type of diode it is to determine the power needed to drive it. Also, I wouldn't recommend driving the diode direct from the batteries, you'll probably end up killing it. Running from 3 AAA is doable, probably...

Older ATI cards (Radeon 9000 and lower) have LM317's, usually in TO-263 package, and I found one on an Nvidia card, once. Most PC motherboards have 1 LM1117/AMS1117, typically around the ATX power connector. I have 4 mobo's from old PC's (Pentium 4 boards) waiting for me to remove the 1117. I...

Hey bluuray, After reading this, I grabbed a bunch of laptop batteries from work and took them apart. In some cases, there is nothing wrong with the cells, but the small circuit board reports issues in error. I have 40 18650's in front of me as I type and all but 5 of them show as holding a...

I may not post much, but I sure read a ton from here, and have learned quite a bit. This is probably one of the most "respective" boards I have been on (no real flame wars that I've seen) and everyone here is genuinely interested in helping each other move their projects forward. So why not...

@532 - Despite not being heat-sinked, the aixiz doesn't get warm on a 30-60 second run. @Antoniio - I bought it from Amazon. It's a Playmates toy Star Trek 2009 Movie phaser. LKY2009 has done a bunch of different phasers and shown them here on LPF. Being a big trekker, I just had to copy one. I...

Inspired by LKY2009's phasers, I did the same. 2009 ST movie phaser, PHR-803t, LM317 driver, and 2 10440 Li-Ion batteries. Sound works, and has a silent mode. Driver is at 88ma. Been 2 months of mucking around with lower powered diodes, learning what works and what doesn't. Got it all sorted...

Hey guys - and sorry for the semi-long post, I'm building (copying) a couple builds from others here on LPF. For testing my first crude test builds, I've been using variable voltage wall warts, but my final builds will use 2 Li-Ion 10440. I've stopped my work, as I'm unsure if there will be...

I don't have numbers (mw) on the lasers... Both are LM317 driven, one is a 2x or 4x DVD burner LD @ 50ma in a reclaimed collimator from a laser level. The other is a 16x Sony DVD burner LD @ 100ma in an aixiz from HTD. I have not pushed the 16x any further, I can't find a reliable consensus on...

Hey guys, I bought some OD4 glasses from DragonLasers, 190-533nm for my PHR builds, and 600-740nm for my LPC815 and other red burner builds. I have not tested the PHR yet, but the red protection seems to work too well. With 2 different reds, I can't see squat. I aimed it at several things, and...

No host yet. I had the driver and the LD in the clips of a "3rd hand" hobby thing. The driver is the standard LM317, set at 95mA using the test load. And yep, it's a 4x burner, I harvested it myself. This one was either from the Toshiba or the BenQ drive. Z

As the title states, two other DVD Burner reds were killed before this one. Found an aixiz in a dead laser level. Pressed the 4x DVD LD, focused as best I could, and tested various current levels. This is running at 95mA. Pushing is what killed my other 4x LD, and the 8x died for unknown...

I was able to extract the LD from it's Al housing. It's a 3mm open can. The ribbon cable is still attached, going to have to be quick removing that tonight. I picked up some Al LED flashlights (UV/White/Red Laser Pointer) to use as hosts, and took one of them apart last night. The LD was...

Thanks Kendall. Good luck with your move and new job. And thanks to everyone else who said he'd come through. Zen

Hey folks, I have a LD from a slim 20xDVD burner from a laptop. The little guy is about half the size of a standard LD, maybe a touch smaller. Does anyone have any experience with these? I would assume that it can't handle the current of a standard LD, so I thought I would ask here for info...

lol... hightechdealz.com.

Anyone know about Kendall? I placed an order with him on Monday, and other than the automated reply from his site, I haven't heard anything. Order still says processing. I sent him an email, but no response... Others from here had good things to say about him, so just wondering what's up...

Hey Everyone, Another new member on the forum, me. I've been interested in lasers for almost 20 years, can even remember doing a school science project on them. This will be my 3rd foray into electronics. My first was car mods (air/fuel mix LED bar tapped into the O2 sensor pre catalytic...
