I couldn't help myself!
Maplins are selling the KAM LaserScan 170 RGY for £100 (at least £30 cheaper than ebay) so I couldn't resist. I know the money could have bought a RGB projector element of good quality but like I said, I couldn't help myself.
It's not too bad. The Red is a bit fatter than the green and it doesn't quite line up right when making Yellow (the red is off to the right and down but being a thicker beam it just catches the green enough to make Yellow).
There's no ILDA input and the scanners are only 15kpps units but it's something I can play with to get an idea on things like the scanner driver board and all the little trimmers on it. I've already found the X/Y input wires from the DMX board to the scanner board so maybe adding ILDA might not be to hard (15k is not great but like I said I'm only playing at this point).
I can't find any info on the parts (no surprise) except the DMX controller is also used in the JB systems 'Smooth Scan Blue' laser unit and has 2 pin sockets for Red, Green and Blue module control (and one labelled as 'I'). It also has 3 unused multi pin sockets and an empty 18 pin IC socket (on board ILDA ?).
The Green laser is fan cooled but the Red is just non-descript and has no visible means of focusing (to me anyway). The dichro is reflect Red/pass green and is just glued to a mount which is then screwed to the laser mounting block so not much in the way of adjustment. All of which means the fat Red/Yellow alignment isn't going to be sorted anytime soon.
The PSU has +/- 15v outputs used by the scanner board as well as +12v outputs used by the laser driver, DMX board and case fan.
All in all, it looks well put together but I did find 1 suspect solder joint on the scanner board (easy fix).
I'll post some pictures at a later date.
Cheers
Colin.
