Thanks James,

 as soon as I know what I've got I'll get back to you, and see what the best option for my situation is.

Dean,

Probably best till wait till after Christmas, my wife is a stickler for keeping her mouth shut, so I'll know very little about it till she hands it over Xmas Day, my fault I know , I married her. 

And by then I'll  probably be able to tell you if it "Can the drive signal be ramped up and down (analog) or TTL (beam on/off)? "

I bet my knowledge of Lasers is less than your of DMX.  I'm learning that as well as I go.  To to bad on midi show control, well the pyro bit anyway.

Thanks guys, no fighting now.  If DIY = Cheap then thats me,,,, Actually I do wish to Do it Myself.   Basically I'm stuck home all day after an industrial accident, was 25 years plus a pyrotechnician and special effects tech. 

I've got into the animated lights and prop scene to pass time. Doing as much myself as possible as my income is pretty reduced.

I have no theoretical knowledge of electronics, but I do solder my own boards if not too complex.  I think I've a usb 8 channel sound card in the loft, somewhere that I don't mind butchering. I also have PICkit 3 and MPLAB

My main controller is DMX with the ability to do 16 universes via 4 slaves. Using hyper DMX updates at 25ms intervals.  (in theory)

I'd like to do two things or at least one of the two.

run the laser via the ILDA interface using a script, or rewrite some of the patterns held by the laser, then DMX them.

Hope this helps..

Thanks for getting back:

I'm not absolutely certain, as my better half has it stashed away as part of my Christmas Gift,   but I think it is this one or very similar spec;

I'm UK voltage 240VAC and 50Hz

Green 150mw
Rated voltage: AC100V-240V/50Hz-60Hz
Power consumption: 10W
Laser wavelength: Green 532nm
Laser source: solid semiconductor laser generator
Laser colour: Green
Laser class: 3B
Scan speed: 20Kpps scanner system
Scan angle: ±40° degrees
Laser graphic frame images: 100+
Control modes: ILDA, DMX512, Sound-activated, Auto, Master/Slave
DMX channels: 10 x DMX512
ILDA: 25pin Sub-D adapter
Cooling system: forced fan

Oh another question, can the preset patterns in these basic set ups be swapped out and replaced?  Reflashed?

Hello, I'm a total newbie (54 y.o English )to the world of lasers, I'm getting a fairly basic green laser for Christmas, to fit in with other bits and pieces I mess with.

I know little of the model etc, but I do know it has DMX and ILDA port. The DMX is not a problem, but reading up on ILDA, I find I need a DAC.  As I'll be using free software, (only need a few basic patterns) .I like to obtain a DIY DAC suitable for use with the free software avaliable or a PCB and BOM. 

I'm not to bad with a soldering iron following directions, but have no idea exactly why I doing what I;m doing if you know what I mean.

Ideally I'd like to slave the software to a full midi show control programme

Your help would be greatly appreciated.

Ian
