Q Light Controller+

I have a raspberry lying around and I had a thought, what if you can have qlc raspberry pi do external broad outputs such as stepper motor, servos, ac motor controllers, LEDs and relays via artnet or acn into qlc. I have search forms and Google and there is not a program for raspberry pi that would do it all. What I am trying to do is make a pcb board using the raspberry pi for a moving head fountain, So stepper motor for movement, servo valves, motor controller for pump, and led ring. So would have a raspberry per head

While theoretically possible, I'm afraid QLC+ doesn't give you enough precision and flexibility to be stable enough. E.g. you may want to control your stepper motors more often than once per dmx frame.

I think pure C/C++ without Xwin or maybe python/ruby with your own event loops might be a better approach.

For your needs, even the raspberry may be an overkill.

On the other hand, I've read somewhere that robe minime contains the original rpi.
However, it displays video so it needs much more processing power.
