Need help with a laser projector

[fomox]

Ok, but wouldnt i need something better than a ScanLSP-20?

[Doc]

Those galvos would be fine to start with, especially for beam shows.

[allthatwhichis]

Not at all; you can have a full RGB on 10k scanners if all you want to do is beams.

[fomox]

Ok, What do i need then to build a RGB scanner then?

[allthatwhichis]

add a cheap red (can be made for almost nothing if you are talented), a blu-ray (same as red), and some dichros and mounts for a small "full color" RBV.

[fomox]

So i can use what I allready got and just add a cheap red and a cheap blu?

[allthatwhichis]

Yep, and you use a dichroic filter for adding the colors together.

Here is a pic of the guts to my first projector...



200mW Maxyzmodule, 50mW big dipper, and a "50mW" CNI with a set of ScanPro30s...

Just replace the 50mW CNI blue with a... 150 to 200mW blu-ray and you whould be good to go. You can see the mounts you will need and on those mounts are the dichroic filters.

[fomox]

Will that say i only need one blu-ray laser and the dichroic filter ?
Or will i need both a red, green and a blu-ray?

[allthatwhichis]

If you already bought a green and a set of scanners, you will need to buy/ build a red and a blu-ray, and then a dichro each, (2 dichros) for two of your lasers, depending on how you lay them out: G->R->Br->scanners, you will need a few mounts for dichros and a mirror or three, and for the above layout, a pass green, reflect red, and a pass red and green, reflect blue dichro, with a mirror to steer the green to the scanners.

And if i havent bought something since i dont have bought something yet
