This doesn't have to do with laser burning, but with the sun and a lens. I was burning though a maxell cd case and it started to smell real bad (I then got a head ache). Later I started thinking, that some plastics have toxic fumes. Hes anyone here melted plastic like this? Are there toxic...

Is it by laser heat or the laser brightness? And what about beam diameter? As it gets bigger power decreases. All lasers have different beam diameters. Would you be able to make a meter with a photoresistor? (including some other parts)

Most say just to buy the parts and make your own laser. But what if I want a green? As far as I know there impossible to make with home appliances. Red lasers are cool. But mainly for burning. Not visibility... So I'm completely stuck on what I CAN do right now... I know I'm really getting to...

I understand that laser light is different than sun light or light bulbs. But why does laser light have a sand like texture if not focused in a small area? It almost looks like the "sand" pieces are floating about 20 mm off the surface. Sorry if this is a nub question. ::)

I see all the DIY tuts on red lasers are using the LM317 chip. Would the 7805 work too?

There moderators SUCK! When ever you say the slightest thing, they delete your post. Like I had a thread with about 28 replies, then I say that one of my orders is taking a while to ship. BOOM they delete my whole thread because I said something "negative" about them. NO, I did not order any...

As the title said. But I noticed that there is no pot on my cheap $5-$10 dollar lasers. Is it still possible (more like, easy) to mod? Thanks in advance!

I took the diode out of an old cd player. Yeah... I know there pretty useless. But I still want to see if I can get it to power up. It has 10 pins, 5 on each side. Anyone know what the power and ground pins are? Thanks in advance.

I live in the US with the freakin' rules... This is what I want. Spot is visible at night: Yes (dah :P) Spot is visible in light: Yes! (also dah) Beam is visible at night: Yes Beam is visible in lightened area: Yes (It does not need to be lightsaber bright, but visible) Can burn things: No I...

What is a good circuit diagram or tut on making one? I don't want to burn out a diode with direct battery to diode. And is it possible to remove only the dvd burner laser without messing the cd drive up? Like still use it in a computer only for reading. (not writing anymore) I have a DVD Multi...

First off, yes I'm new here. ;D Anyway, I live in the US. Would it be illegal for me to buy the 15mW X-Series from novalasers? No I'm not planning on pointing at plains or cops cars.
