is there a possibility for a 30 degree rather than a 90 degree, like a custom lens or something? Right now we are only shooting at 7 meters, with silhouette targets being rather large, still, if the width is considerably greater than 1 meter at 5+ meters, that's a bit much. At 90 degrees the...

So I went to the Fry's again, and we bought two different colored spools of 26 gauge copper wire, a 4001 diode, two 10 ohm resistors, an extech mn36 autoranging multimeter shown here, and my first breadboard. Fry's did not have any pots anywhere closer to 25-100 ohms, but they had several in...

induction and charging options? I get worried about my 1W laser overheating after just a few minutes, so we don't use it but a couple of minutes a day before putting it into storage, which ironically is in a black bag about 8 inches from my wifi box. perhaps the host could be set up to still...

I think the most telling thing for me was the refraction facts on high mW lasers. See, even 5% of 200mW is still 10mW, and a lot of stuff in your house is going to partially reflect back at you. I guess the closest analogy is saying something like "your laser is like a torch for your eyeballs...

what's a diode press? I've heard horror stories about people using various clamps and it seems like "vice grip" is really popular for some people. I was about to go get a multimeter but a lot of the brands don't do over 200mA. What kind of multimeter is good for these 5mW to 3000mW lasers, or...

Inductive Recharging? Check this out: Airnergy WiFi power system gives RCA a reason to exist (video) -- Engadget I've been looking into this wireless thing on and off for a couple of years, and it seems to me there's no logical reason aside from space and cost that would prevent you from...

The metal limitation is definitely an issue, although I think the aesthetic in terms of inductive recharging vs. taking the batteries out is a smaller consideration, which is probably why Sonicare did it in the first place - then again, the argument could be made that all induction devices are...

I've been thinking about the Sonicare toothbrush, ever since I got one years ago it has reminded me of some kind of laser device. Two things fascinated me about this tool, 1) it has a really nifty blinking LED charge indicator with bars; 2) it doesn't actually require physical contact to...

it looks like an excellent "everyday carry" :)

In following with BB's post, I returned the 60/40 to the store and got some 63/37 solder instead. also got a "third hand" w/ magnifier. What parts do I need to buy to make a driver? edit: found this thread http://laserpointerforums.com/f67/lm1085-diy-driver-62227.html Going to probably mess...

pic posted of wire and board.

i've got solder, but what is flux? I saw some giant containers of some sort of highly corrosive stuff at the Fry's near the copper scratch boards and the soldering irons, but I wasn't really sure what it was for.

Any idea how much the cross in this video (time: 2:50-2:57) 1W Spartan 447nm demonstration and Arctic Lens's attached! - YouTube diffuses the light? I'm just going to guess around x1/200-300 based on the frame in 2:57 but I noticed with these alternative lenses, the center of the patterns is...

So I went to the Fry's and bought a Hakko FX 888 soldering station here's a picture on amazon, and some 60/40 23 gauge solder, and a prototyping board from twin industries with plated holes. I haven't opened or used any of these products because I'm not sure if I'm 1. buying the right kind of...

what is a PCB? I'm trying to find out what those round drivers are called so I can buy them, but I was only able to see images by typing "LED PCB" in google images. When I tried finding how to cut a circle out of veroboard, I saw recommendations for a hacksaw but they said a hex or octagon...

hi, I've been wondering what the safe/recommended mW for a rifle/pistol mounted tactical laser is? I've got an idea for a laser that uses a cross lens adapter like the ones used in cross line levelers, and I'm not sure how low I should take the mW. I've seen ranges of 5mW to 20mW and I...

So I went to the Fry's electronics store to purchase my first soldering iron and parts, and I noticed they had silver solder, but it needed a hotter iron, and they were trying to sell me a digital iron but those were like 2-10 times more expensive - some were over $200. I also noted some had...

actually I think you are right no topic. The purpose of this thread is to push the limits of "portable, self contained' lasers, especially diodes. Which reminds me, if a backpack is required to power the thing, while it is technically portable, I'm not sure it really qualifies as being smaller...

I wish I knew enough about lasers to know if that would be enough to power a 1300mW, but right now I'm like a kid who's trying to explain since a truck has a bigger gas tank than a car it can pull more weight. I think it's what's under the hood that probably matters - but bigger tanks probably...

practical is completely out of the question - I mean the only plus we've secured so far is the ability to burn "white", but with something like 3W white knife edges, I think safety isn't going to be much different from any other class 4. For useful burning specs, here's some benchmarks to think...
