A little question for laser afficionados or people with experience regarding to this.

I'm would like to control a laser in realtime, through DMX, and am wondering whether this is at all possible. Most laser use a set of stored frames which can be recalled / displaced, but not make these frames on the fly.

Maybe it is possible but I haven't found any info on this as of yet. Any pointers, links, ideas,... are greatly appreciated.

I was looking into this too. It seems possible to build a DMX shield

I was looking into this too. It seems possible to build a DMX shield  
for the arduino:

I'm very new to this, so correct me if I'm wrong, but it doesn't seem 

to me that this would allow me to send jitter generated imagery in

Thanks for the info!

to me that this would allow me to send jitter generated imagery in  
realtime to the
laser...?

i am interested in this as well ,and just started to do some research about how to use laser with jitter.

or would you like to to create an rgb image with a rack of lasers ( which might be complex but that is what i am interested in myself )

are you trying to draw with a laser ?

What I basically want to do is use a single color laser and draw 

patterns which can change on a frame by frame basis.

The patterns need to be produced dynamically, i.e. they cannot be a 

set of stored patterns in the laser which are recalled, translated, 

Al these effects should be done in jitter, with the realtime changes

in jitter communicated to the laser.

The following instructable uses a 35mm slide, but you can maybe find 

an lcd display with video input that you can can project the laser 

through instead. I have not tried this tho, just found it, and there

are some caution flags.

Hi Brecht, Kinomatic, Karrlo - did you get this to work? I'm working on something similar at the moment
