im building a custom laser installation, it requires 3 analog control signals of 0-5v to control the color and brightness of the beam.
i was considering using an arduino something and one of these to output the analog waveforms:
However, given that Pixelblaze software is specifically designed to produce nice rgb lighting effects it would be great if i could use my pixelblaze.
is such a thing possible? anyone done it?
You can get standalone (i.e. LED-free) ws2812b chips, and probably others, so I don’t see why this wouldn’t work. Folks with more than basic understanding of electronics might have a more refined opinion!
I think you might have luck using a WS2811 breakout board (we sell these) and some PNP transistors to switch the positive side power for the laser. I know at at least one other person that has gone that route to control laser diodes like you might find in a laser pointer.
If its a more powerful laser and these are indeed analog control signals, you might be able to filter the output to an analog signal.
