RGV / Green hybrid

[buffo]

would software or hardware be the better choice here? i ask because i dont have an opinion, but im interested in the answer.

Well, his original idea was to be able to have the projector switch from balanced RGB to full power (green-heavy) operation based on whether it was displaying graphics or beams. In that case, it would seem to me that a software solution would be best. Otherwise you're going to have to go out to the projector to make the switch, and if the projector is mounted 10 ft off the floor (as is required here in the US), that's not going to be easy.

But from a purely abstract point of view, either method would work. I just think that software control is easier for the operator.

hm... im really rather for setting a new standard in rgv projectors... using the "I" channel for bluray too. = if you projecting a graphic show on a screen, you drive the 405nm lower to get a blue through flourescense. and at beamshows you drive it harder to match up with the other lasers and adding a bit green to make blue!

That's not the way the intensity signal works. Intensity is on (high) any time there is output - no matter what color is being displayed. So if you connect your blu-ray to the intensity output you'll have violet being added all the time - even when you're trying to display just red or just green.

If you want a separate violet channel, there is already an accepted standard for it. Violet is one of the 6 color channels specified by the ILDA standard. Just connect your blu-ray laser to the violet channel and train your color palette and you're all set. Pangolin has always supported this, but some of the cheaper controllers do not.

Your suggestion would break the ILDA standard.

yeah, i know. this would be rather a nice solution for the soundcard dac. i think so the 4th channel we have there could be better used. cheap dac = probably only 405nm, you understand ^^ just forgot to mention it.
but this of course would require to modify the dll so you can set violet to the appropriate channel in your show soft but in real the driver will send the signal on the "I" output of your ezauddac. crazy idea, nah?

The other problem is this: What happens when you plug your sound card DAC into someone else's ilda-compliant projector? Or, what happens when you upgrade your DAC and plug your modified projector into an ilda-compliant controller?

This is why there are standards.

Sure, you could do something different so long as you only use your own gear, but you're taking a real chance if you ever try to play with others...
