Controlling laser head using TTL PWM

Troubleshooting
1

Hello all,

I have been playing around with an RGB laser head and have been wondering if I’m able to control it using a pixelblaze. I have managed to get things rolling with WLED but I’d like to be able to connect it to my friend’s pixelblaze network. The laser head controller uses a separate TTL PWM channel for the red, green and blue diodes, 3.3V logic has been working so far.

It seems the pixelblaze is primarily set up for 3-4 pin ARGB strips, has anyone tried controlling a laser with this type of controller? If so, how might I go about doing that. Could the GPIO pins be used without having to write a new library?

Thanks,
Toog

I have been thinking about this too but hadn’t looked into the laser hardware side. You can buy separate WS2812 chips so maybe you could just hook up a bunch of those to your PB and connect the outputs to the LEDs.

Okay, I will check that out and see if it seems viable.
