R: R: Vector games on Laser show hardware

"The only "problem" is to convert the output of the vector generator into a
differential signal."

I think XY asteroids output circuit is a good start. asteroids supports -x
and -y signals too if "cocktail table" mode is activated. with an easy
modification X, Y, -X and -Y are generated at the same time in a very simple
way.
THis circuit can be easily reproduced and used between a game (or zvg) and
ILDA interface. A couple of pots can be addeed in order to regulate all
signals.

This project of you guys keeps coming up in my brain.
I think it's an awesome idea.

Now; I've come up with some initial brainfarts based upon some quick google
searches:

First; It appears that an iLDA compatible laser projector might fit this
project exactly:
http://www.laserist.org/StandardsDocs/ISP05-finaldraft.pdf
see pp8

says X,Y is +/-10
RGB is 0-5V
These almost match the output of my sega g08.

The only "problem" is to convert the output of the vector generator into a
differential signal. Probably a "simple" differential opamp would foot the
bill.

China seems to have a inexpensive RGB iLDA projector:

ed-50mw-532nm-green-150mw-450nm-blue-laser.html
My concern of course is it's china merchandise. Unsure of the quality, MTBF,
etc.
Anyone know of a better deal / manufacturer?

I *SO* want to embark on this project; just wish I had the time.
My find the time... need some encouragement. :P

Comments / suggestions?

hi all..

I know some of you have tried this out before, the last time i seriously
looked into this was about 10 years ago.. one would hope the hardware has
come down in price sicne then, or is more easily available...

So can anyone reccomend a certain laser show control system, makes/models
of steerable lasers that are up to the job? Mono or colour (if possible)
