Wow, you fork out for FB3 and over a watt of lasers but you only buy ScanPro20 galvos? Anyways the pics look great.

Thanks everyone!

I don't really need anything faster. I'm not doing graphics. The green wasn't supposed to be that powerful, but I thought it better to use my existing 1W than to buy another 300mW.

Amazing! I see your camera has taken some abuse already.
The first camera I used was my girlfriend's old camera. It took a hit from a liquid sky a while ago and a few from this projector (so by no means a static beam). I'm not sure why it was so sensitive to laser radiation. In any case, halfway through, it died. :-? I'm not sure if it was laser related or not and I switched to another camera. You might have noticed not all of them have the burns.

Woah! I sure hope that camera wasn't expensive..... Was that done by direct exposure? I don't want to break my £300+ camera... Very nice build nonetheless - if only I had that much money...
It was $50 if I remember correctly. The $110 camera took the scanned beams without complaint.

Is your DAC inside the casing ?
Yes - it's just under the main 5V psu (from an older computer). The ILDA cable comes out and loops back in. I had ease of upgrades and interchangeability in mind during the build. It will accept any ILDA signal.

Yeah, I thought of doing that as well when I have a good case for my scanner. seems a bit easier IMO.

Once again, very nice scanner, +1

Coolest computer I've ever seen! +1. ;) I like how the fan turns green. ;D

But why was the red beam so wide?

Man, If I ever do any type of scanner, I might have to steal this idea of housing it in a computer.

Great job man, That's a fantastic build.

red lasers, especially high powered ones have really terrible beam specs

heck just compare say a DX greenie to a red laser in an axiz module

the beam on the red is significantly larger

This is only diode red lasers though, gas and DPSS have thinner beams, with much better beam specs.

The beam on my red is about 5x8mm. I haven't measured the divergence, but I'd guess it's ~2mRad. The problem with gas, is twice the power is needed to achieve similar luminous efficacy unless it's a HeNe, which tops off at 100mW anyway. A 1W krypton laser is probably going to be 5 times or more (used) than what I paid for my red, and it'll take at least 1000 times more power in addition to 1 gallon per minute or more of cooling water. It also won't fit in a computer case.

DPSS requires about 6 times the power to achieve similar luminous efficacy. A 3W DPSS is much larger, inherently more than six times as dangerous, and thirty times the price.

There are 642nm modules available that would have decent specs, but they're also quite a bit more $.

I've kind of taken a liking to the white/yellow/magenta beam shrouded with a red aura anyway. You have to be looking for it to notice it, and even then, you can only see it in single beams. Andy'll tell ya - he's got one, too.

well nearly 2 years late but I'm going to say it anyway, awesome build Cyparagon. I actually agree with you with the red aura, makes the other colours stand out more I feel.

same here - 2 years late but wow, I have computer cases everywhere (and some good looking ones too, not just beige boxes). I might have to also use this idea for my homebuild projector.
