Would the level of attenuation through laser goggles scale linearly with output power?

Ah, so fluorescent candy, makes you wonder if Uranium doped gummy bears are in the near future:)

What is going on in this video? I take it as shining diff lasers at diff objects to see the effect. Is that a lead wine glass?

Nice build, congrats on 1st:) Btw, if you just hold the camera a little farther away, it will focus. Find a distance that works, it'll make the items seem smaller, but you can crop out JUST that part of the photo. That will also produce smaller pictures:) Oh, and looks like you're using a...

Re: Group Buy for LPC-815, SF-AW210, PHR-803T, and GBW-H10L - Cheap! Yea, I understand, maybe this won't be an option for everyone. I personally don't need that many sleds. Maybe some people would be interested if it meant not getting any at all. I dunno...

There is a group-buy going on right now and you can get LPC-815 sleds for ~$5. http://laserpointerforums.com/f55/group-buy-lpc-815-sf-aw210-phr-803t-gbw-h10l-cheap-55994.html

Hey, you should also consider getting some really cheap BURNING diodes from this group-buy that is running right now. http://laserpointerforums.com/f55/group-buy-lpc-815-sf-aw210-phr-803t-gbw-h10l-cheap-55994.html Compared to the price you pay for ONE 445 you can get 10 red/violet ones. These...

Re: Group Buy for LPC-815, SF-AW210, PHR-803T, and GBW-H10L - Cheap! Looks like it's been going at ~100 sleds/week. Why not give it at least until next sunday? It might slow down as more and more people get their orders in, but this is a pretty big order, isn't it? Another idea, what if...

:gj: man! Be careful running with that end-cap, I've read that they can cause damage to the diode :eek: I'm working on one of those myself, so glad to see other users building non-445 lasers:beer:

Is this what you tried? It works on FF and IE for me, but this could be controlled by my browser settings... <form action="mailto:myforms@mydomain.com"> You have 2 choices: - "passive": rely on user's computer to have an email client and use the 'mailto:' - "active": using a script on the...

Hey dude, great green build in that coll DX flashlight! I'd give you my new 2 rep points, but I already repped you for your active cooling build:)

Great looking laser! I like the host, and the whole thing as a laser just looks so "technical" :)

LtKernelPanic, I think you have your potentiometer connected as a constant resistor. If you connect the outer 2 legs you get the pot's full resistance all the time. You need to use the middle pin to get variable resistance. In the DDL schematic it's shown as 2 pins, middle and one side...

Oh, that's not a real wire in your picture, I thought you already soldered that red line in :) It will not matter which slot you put that in, if you do what Udanis said.

There is a guy that can actually do this :drool: with his eyes :eek: YouTube - Bug eyes, bug eyed guy Joe Jones amazes the world...

Do you have said 10440's on hand now? Plug them in and see what voltage you get.

The lightsaber can be used by regular people, not just Jedi. In one of the new star wars movies they had a robot wield like 8 of them to fight one of the good guys. So I think the plasma containment field is a built-in feature. The reason only Jedi are successful at using a lightsaber is...

What wheel-combining technique do you use, and what's the efficiency? :crackup:

I have used a slightly defocused 30mW 405nm $9 pointer to scare a skunk away from our tent while camping with GF. I also had a 40mW 532nm pointer on me. I noticed the skunk did not care about the green, but would get scared of the violet. I attribute this to the same feeling we get when we...
