Brilliant, I’ll forward that link to the creator

Pretty good for some arduinos, an xbee pair and 2m of ws2801 led strip All from one of your distributors if that is the angle you’re after

Wow, spinning string… Not sure on the noise either…

too much IRC?

I would suggest using a hardware pwm and a mux ic considering you only need one at a time
Same pins could be used for another mux ic for the receivers
Something like the 4067 breakout you have would be perfect -
looks like GPS-00177

3 days ago i would have bought a box of these

Through hole is available still

Another common programming method for the quadrature encoder is to have a state change interrupt monitoring A
When the interrupt is activated:
If A is high we have a rising edge and proceed, else we end here
If B is high, the position in incremented
If B is low, the position is decremented
This code has been tried and tested on an arduino monitoring 7 encoders
No public wish lists :(
