Default Basic Scanner Questions

I am looking at building a scanner, and I am quite confused about a few things

First, I see a lot of people use sound card DACs. AFAIK, A DAC is basically a USB - ILDA converter. If I pick any lasershow software will it work with any DAC?

Second, on feeBay, I see a lot of DACs (ex: "DAC DESTROYER" HAND SOLDERED USB DAC w LINE / HEAD OUT | eBay). This looks like a sound card. Am I even on the right track?

Third, the lasers plug into the galvo drivers I assume. Does it power the laser, or is it TTL based?

Thanks in advance,
Jacob

Default Re: Basic Scaner Questions

Distinction: A projector is the whole thing. The scanners are the parts that scan the beam.

DAC stands for digital-to-analog converter. You can't just search the internet for "DAC;" this is too broad a definition. The one you linked is just a USB sound card (sound cards ARE DACs) - it won't work for lasers. It needs to have many channels, and needs amplification on the output of each channel.

The lasers plug into a power supply, and the modulation input is coupled with the signal coming from the DAC. The DAC has a minimum of X, Y, R, G, and B outputs. X and Y are for the scanners, and RGB for the respective laser colors.

The scanners are always analog. The lasers can either be TTL or analog.

Software only tends to work on a few DACs. There is no software that works on all DACs, and there are no DACs that work with all software. As far as choosing a DAC, it would help if we knew your budget.

That all makes sense. I am trying to keep this <$300 for everything except the lasers. The only DAC I have seen that is in budget is iShow. Any suggestions?

Do NOT get ishow. Anyone in the business will tell you it is utterly worthless. Stick with the soundcard DAC tutorial thread hanging around here somewhere.

Default Re: Basic Scanner Questions

well technically the galvos scan the image not project it so its a scanner .....

also sound card dacs work with allot of software, *********, LSX, LFI, etc

but FB3 comes with its own DAC

you can build a laserboy carrection amp or you can buy a audiolase DAC there's allot of options as far as sound card dac's go

Default Re: Basic Scanner Questions

The industry calls it a projector. If you call them scanners, you won't be talking about the same thing as the rest of the world.

Similarly, if you ask someone where you can find a flash light (but in your mind you're thinking about a xenon flash tube for a camera - after all it is a light that flashes, right?) you won't get the response you want.
