I repainted the phaser, I'll take some pictures of it tomorrow, my neighbor borrowed my tripod, and I've given up on taking a decent picture of anything closeup without it. That's the one thing about the Rubie's model, it has to be painted, and paint doesn't like sticking to plastic very much...

This setup won't draw enough to notice, it's minute, by comparison, not even one percent. These batteries have current to spare, they are made to be shorted out. So you also never need protection circuitry, or any of that. They have to be charged like other lithium batteries, but that's where...

You should really ditch the button cells, and get some of these, instead. They are quite efficient for running things like the soundboard. 5 x L78L33ACZ 78L33 + 3.3V Voltage Regulator IC TO-92 | eBay These are perfect and easy to do, they have 3 pins, in, out, and ground. You solder the ground...

The trick with the batteries is EFEST makes more than one kind of lithium battery. We really need the high drain type, IMR if we are going to get away with using the dinkiest ones to run the biggest laser we could get, you know? I used these: 2 NEW EFEST IMR 10440 Li-Mn RECHARGEABLE BATTERY 3.7v...

If you don't mind me asking, how much laser have you managed to stuff into Rubie's phaser, and what did you use for a power supply? Ruby only allocated us room for 2 AAA cells, and personally, I thought that using IMR 10440 cells was a stroke of genius. I have the NUBM44 and a 4.5A driver in...

Yep, the Rubie's, it's turned out to be the best host of the bunch. And this is what I used for a heat sink, it was $5. I smoothed off the edges on it a bit, and dug as much materiel as I could from inside the orange knob thing, and after a coat of silver paint, I drove it over the fins with...

I'd sure like to push the little IMR 10440 batteries as hard as I can, say, just one cell into a boost type regulator. I'm using two cells, now, since the regulator I have is the buck type, and needs a higher voltage to operate. I bet it'll do it, but again, for only half as long, or less. The...

That is an interesting color! That's what I guess I wanted to know, although I have to confess that now, I'm really, really, curious to find out what the hell they use these for, six grand is a bit steep for a laser pointer, you know? Surely, there is something that requires one of these, but...

The host is a phaser, and it's the cheapest one. It had plenty of room for a heatsink, so that isn't an issue. But it only had room in the handle for 2 AAA cells. The first one I built I used a Playmates phaser, and it had a slightly larger handle to hold 2 AA cells, but it was too big, and...

This site lists thousands of diodes, I just sort of stumbled into it by accident, but here it is: https://www.laserdiodesource.com/

My latest build only had room for 2 AAA cells. I have it running on 2, high drain IMR 10440 cells (not ICR cells), these are the kind that they use in e-cigs and vape pens. It'll run it for 2 minutes or so, at the most. But this is a very impressive showing for such tiny little batteries! I just...

Is that yellow? First time I have heard of such a thing. https://www.laserdiodesource.com/shop/561nm-50mW-scientific-series-laser-module

I built my own driver out of an LM317, a couple of them in fact. There are 2 ways to rig an LM317, either in voltage regulation, or current regulation configuration. I run mine from a single lithium cell with no issues, at least not for average power diodes like red. One of my projects is an...

I have been trying to get the perfect night vision scope dual wave laser dot sight for my BB machine gun together for a very long time, now. I modified an old gen 1 night vision monocular onto an electronics project case from Radio shack that serves as the rail mount, and holds all the...

Failed miserably, for reasons unknown.

O-like is selling 3.5 watt diodes for $600, so any legit 3.5 watt laser would have to cost a lot more than that. I have seen lithium batteries explode, it's extremely unpleasant. It's less like an explosion, and more like a big ball of fire that burns your house down. "POOF!"

Here is one that I fried, somehow. This is projected without a lens.

So I have an interesting idea, I have a dvd burner that could donate it's laser sled, is there not a beam converging crystal of some kind in there? As it happens, the host is ample enough to take the whole sled, so what I would need to figure out is where/how to place a collumation lens, any...

That's why I used 2 LM350's. I have a voltage regulator feeding the current regulator, so I can adjust both the voltage and the current for different diodes. Reds like low voltage, while blues like more, and the new green diodes are outrageous, they like a lot more voltage. By feeding the thing...
