i saw this effect last year. what was happening was it was being shot from a tower, close to horizontally. from your viewpoint, since it was coming towards you, it looked like it was going up. now jumping to once it passed you, it was heading towards the mountains in the distance, making it look...

Thanks! This is really helpful, I appreciate the post! My project has been on hold for a little while, just changed jobs, but I hope to get started on it again soon!

Re: Free goggles, anyone? I'd like to enter into this, if I qualify :) I'd be interested in the OD 4.1+ glasses. I have a Wicked Arctic and just the shitty glasses they came with, and I'm in the process of building a ~1.5-2W 445nm laser cutter, and will need something better than what I have...

I'm thinking of making my own. I think I saw somewhere on here some simple circuit where a soldered on resister of a chosen resistance is what determines the output. Does anyone know what I'm talking about or where to find this? Since I don't have a spec sheet on these diodes, I don't know what...

ok, so i just received 16 adjustable housings to fit the diodes, next big step is getting or making the drivers for them. i don't think they need to be exceptionally adjustable once i figure out the right output, so am i correct to think it would be easier and cheaper to just make a bunch of...

Attached are the diodes I've been able to pull. The 3 on the left are from the desktop burners, the 3 on the right are from the laptop. Not really sure as to what I can do with the laptop diodes, after some searching around on here, it seems like not much. That being said, if anyone on here can...

Thanks for the input, guys, I'll check out getting some of those AixiZ housings and drivers! I was thinking about 3D printing some hosts for them, but I'll see how that goes. I already have a whole little box of various springs. What kind of battery would I need to drive the diode with a driver...

I just scored 33 free DVD burners, and need something to do with them. The 18 desktop burners in the back are all 16x, and the 15 laptop burners are I believe 8x. I've already taken apart a couple of them and (safely) extracted 6 of the 16x burner diodes. I'm guessing I'll turn all of the 16x's...

Nice find of Dank, giving you +1 for that one :) I'll have to look into Mach3 some more, but I'm guessing Arduino would work fine for this project. The LPT connection method seems really nice, but since this is all going in a small apartment and I'm using a small netbook to control everything...

Very interesting, good to know! What kind of tech is needed for something like this? That is to say, I assume the LPT will have to connect to something like a stepper controller (like EasyStepper) to apply proper current and voltage to the steppers (and the LPT is just sending steps and...

Great idea about the positive pressured tube, I hadn't thought of that! I know just how I could do that by tapping into the same fan output blowing across the heatsink. I haven't heard much about Mach3, other than maybe hearing it mentioned here and there.. what is it exactly? Software...

Thanks for the insight, guys. I'll probably spring for the 9mm in the next week or so once some more money comes in. I can use that time to search around for the best price (any suggestions?). I can probably have a fan blowing on the surface of what's being cut to try to extinguish any flames...

So after looking into this some more, it's looking like I've got the 9mm in my sights. I know when people make pointers, there's typically a small duty cycle on it, but for a project like this, I think it'll be on for some amount of time longer than that of a pointer. Is there something I can do...

Thanks Things, I was hoping you might chime in (after reading some of your posts in other threads). That was about what I was expecting, but wasn't completely sure. I've seen some people making pointers that go up to as much as 3W; is that using a similar diode and just pushing it harder with...

Thank you for the welcome :) I've been lurking around on here trying to pick up some information where I can, but thought I'd try to gi to the source directly by asking a question. I figured the diode would need some cooling, and was thinking a heatsink, possibly with a fan blowing on it...
