I am also looking for a driver. I'm looking for a boost driver which can go to 6v off a single li-ion, and I will be running this somewhere around 350-500ma. DTR had exactly what I want, but is out of stock. Anyone have any suggestions? I found a place in the UK, but I'm in the states...

I want to build a line generator for a hand held laser.. would I be be better off w/ spinning mirrors, or a glass optic? Space isn't really a concern, as I was going to build a 3 motor spiro into this.. so, either option will be smaller than my original plan. I guess, which has the least...

I've been thinking it would be fun to have extremely precise control of a spiro. You could even do math with it, and dial up specific patterns! (like, #1 rotating at 80rpm, #2 at 160rpm #3 at 120rpm). And, having the speed STICK is a concern, too. Even w/ PWM, regular DC motors drift around...

Has anyone used the meredith lens assembly and glass lenses w/ one of these diodes? I didn't find anything searching this forum for 'meredith'. I may try it unless it is a bad idea for some reason.

Was going through new years eve photos...

I'm looking for a small momentary, pushbutton switch, like a tactile switch. I can't find any small switches that are rated for over 50ma. The laser is pulling at least 3x that. Can little tactile switches take more current than they are rated for?

I got one of the 50mw aixiz modules from ebay, and it doesn't work. They're sending a replacement, and their service is great! But, I don't think he wants this one back. It does not emit any green light, and while I was poking around on it, I noticed out of the corner of my eye a faint, deep...

My argon has no lens. The beam diverges, maybe an inch after 10 meters.. probably a little more. If I measure the divergence, is there a way to find a lens which will correct it? Then I guess the problem is finding a way to mount it. The laser just has a brass tube at the end. (Omnichrome, from...

Everyone's always saying "these blu-ray diodes don't get that hot..  Even in just the heatsink they came in"  So, I had one hooked up for testing..  150ma..  It is HOT!  I got my finger wet and touched it and it sizzled.  That's after being on for about 10 seconds.   is this right??  They all...

I just extracted a diode from an LG.  The unit had one flat plastic diode, and one can.  I'm guessing the can was the correct one, because it did light red.  Only about 2mw worth though :(.  I don't think I made any mistakes this time either.. Gentle extraction, gentle insertion into the...

I made a post a couple of months ago asking about a beam artifact from my B.R.   Every diode Ive tried has done this.  i couldn't get a good photo, and tried to explain it.  The topic was just sort of dismissed.  A couple of people said they couldn't get a good focus, but no one really...

Well... each time I have to rebuild my laser, I get a little more ballzy.   I brought mine to a party last weekend, and too many people wanted to play w/ it.  It got dropped, people tried unscrewing the top (mxdl build) and twisted it around.  It worked that night, but not the next day.  A leg...

I've noticed people buying 5, 10, 20, etc, drives or diodes, so I'm sure you're building a few lasers to sell. I've got a couple of extra diodes and would love to build a nice laser to sell, to maybe get back a little of the money I've spent on this. So, Where do people sell high powered...

There were a few posts here about why blu-rays seems to burn better than red...  I was playing w/ both last night.  My blu-ray is ~100mw, and the red is ~300mw. Blu-ray definitely burned almost as well as the red on most surfaces, and burned better than the red on some!   I could ignite white...

I got a diode today to replace one I killed last week. When I focus it, there are a few artifacts. to one side of the dot is a small line, then another longer line. (they're more like long smudgy dots than lines, if that helps you picture it) I didn't notice the same thing on the diode I had...

I'm continuing this from my "optiarc - no can" thread. I got the open can out of another drive, and am having some issues. I built the CCS w/ lm317 (3x10ohm resistors/no pot). I'm using 4-aaa batteries. When I test the circuit w/ no load, I get about 370ma and 5v. I test the circuit w/ the...

I pulled the leg off of my favorite green pointer today. I bought this thing way back, about 10 years ago. (maybe 8 years) and it was not cheap at the time. It was sold to me as being 40mw. It was definitely stronger than the other green pointer I had at the time which was sold to me as 10mw...

I just got 3 sony optiarc 20x dvd burnerss in the mail, and I can't find the diode can's in them! there are these little plastic rectangles which appear to be the lasers! did I just waste a bunch of money?
