Oh yeah =P - it's great when I show it to a friend and he's like "Wow, where did you get that" "Oh, you know, I just BUILT it!"

Mine is instant. I can literally write. Not as fast as with a pen, but close. I can burn through white cloth as well, like a blanket. Much slower though. EDIT: Jesus Christ, that's huge. How do I resize that?

Cutting edge technology.

Circular is usually considered better, simply because it boasts a "Higher beam quality," but as random said, you probably won't notice anyway.

Special thanks to Jayrob, Daguin, Ash, and all those other people who answered my endless questions. I'm just going to upload all these photos without a description, I'm sure you guys know what it all is. If you have any questions about my build let me know. Click them for a larger image.

My focused DIY build (well under a watt) burns white paper.

Ah okay, I've figured everything out. I had the lens in backwards. Then I fixed my focus issue by just slowly adjusting the module in the heatsink. We now have a nice round dot. I bet this will fix my power issues (I was only getting 500-600mw) as well. Ash, I'm forever indebted to you...

There is a cylindrical module. At one end of this module there is a lens. The side with the lens is screwed into the EzFocus adaptor so that the lens is closest to the adaptor (The lens side faces out of the laser, rather than towards the diode. As I said right now I can't unscrew it. trying to...

I have a lens that looks like this ------...........| ....lens.-->.....| ------...........| The lens sits at the end of a cylindrical module with threads. I then thread it into the EzFocus adaptor represented by the vertical line in the direction of the arrow. Is that backwards? EDIT: Crap, I...

The multiple responses describing blue almost make me question my diode. Everyone that I ask also sees violet (when shot into the black night sky). But I see blue only when reflected off of a white surface.

Ehh, in our lab we've got multiple lasers at well over 100-150 watts...

I've only actually looked at the beam outdoors (shining it into the sky). I don't have anywhere to shine it inside without it being potentially eye damaging...

I think there was another thread about it somewhere, entitled "How do YOU see 445" but I can't find it - So I'm going to ask the question again! I see 445nm as almost a brighter 405nm, completely purple, but just a bit lighter and brighter. I see 0% blue in 445, nothing like what pictures show.

Ah. I tried doing that, but at long distances the dot is very, VERY large. And the beam distribution is not very Gaussian, it looks alot like the picture of the 445 laser through the 405 lens, the picture is in a thread entitled something like 405-G-1 vs 445 AixiZ (I can't find it!) Also, great...

It's alive! Terrible divergence, but it's working. I'm working on getting the focus adjusted - it looks like this laser is going to be mostly for burning, as it gets severly out of focus quickly. I'm not sure how to focus it to infinity, as I've heard done. Any comments on that?

Regarding a pilot, there is a safety story we tell at the lab I work at (truth or not, I'm not sure). A guy once borrowing a very high powered laser from the lab to trim a tree he couldn't reach - with no thought to the beam that was going into the atmosphere. (It was also a laser that was...

Re: Use the Edit and Multiquote buttons When you say Nimh, do you just mean AA? Would 3 AA's actually power this thing? (I can be patient if I need too, but the suspense is killing me =P I didn't do that, thanks for the tip. I read that, just wasn't aware of what it meant in terms of my...

Great ideas both, I'll see what if I can find any rare earth magnets at the lab today, and if not I'll just spring for foil. Thanks guys! EDIT: Tried it with the aluminum foil, and the laser did not work. So I either screwed something up in the build, or the battery isn't good enough to power...

Ah. Very interesting, I didn't know that.

I have.
