1 lets say 180mw of 405 = roughly what in 473?
1watt 457 = roughly what in 473?
i know its subjective im just looking for a rough estimate.
2 also some green lasers are wired to red ilda why is this?
3 differential advantages/disadvantages over single ended
especially thru about 40m of ilda cable linked to 3 lasers using splitters or ilda passthru on the projectors.
1. Use chroma and look at luminosity values
2. Ilda standard states that monochrome lasers should be wired to the red input
3. Differential receivers are a great way to eliminate noise picked up trough your cables ... :)
I've mine wired to the intensity output.Quote:

The problem I have seen when wiring the laser to the intensity output is you cannot control the brightness of the laser and it will be full power when on.Quote:

Now I have connected my green to the green instead of intensity and made a green color pallet for it and I have brightness control with livepro.
It sounds like Pangolin uses the intensity signal as some LASER on/off signal, instead of for intensity modulation. I connected my modulation to the intensity signal and got full depth of modulation with both HE-Laserscan and the Zoof software. Unfortunately the ILDA standard is not perfectly clear on this point, so I guess everybody has to do what works with their software.Quote:

according to the nice Chroma program ;)
All equal amount of lm (70.7lm) :
405nm 22.2W
445nm 2.44W
457nm 1.89W
473nm 1W
About the wiring of a single colour projector ...
I've just been thinking that it's much smarter to wire to one of the colour channels ...
That way, you can make nice chase effects using only one DAC, by changing the coulour in software you can switch between multiple projectors wired to different colour channels.
For example :
Projector 1 : wired to green
Projector 2 : wired to red
=> Yellow in software : both projectors outputting the same thing
=> Frame with red and green stuff : both projectors outputting completely different stuff (do mind that they both will be scanning everything for both projectors so keep an eye on the max points)
=> Colour cycle that changes between red/yellow/green : Interesting chase effects between projectors :)
Interesting idea.
You also need to make a new color pallete for this to make sure yellow = green @ 100% and red @ 100%.
Making a workspace for this is not that difficult, you only need to change the color cycles.
