Dmx controlled pulleys

- These are two 12v stepper motors configured to monitor DMX light control signals for forward or backward speed control. We will be using them to harrowingly propel the small speck of dust on which all of Whoville resides. Hopefully later we will find many other uses. These controllers have 8 DIP switches on the side that can be used to set any DMX channel between 0 and 255.
We've got foam ones we are going to project onto for a holiday display. Your solution seems like the most cost effective dmx solution for this. I may have questions later.
Hey Michael, this is the first I've seen too where it's a pulley to move a prop. I'd like to work with you to build these for our 2021 halloween show. I want some that can raise / lower pumpkins .
With some beefier motors, you could raise and lower real pumpkins, but I highly recommend carving them from styrofoam so you don't need a such a loud motor to move them around. If you make them out of foam, you can pre-shatter them so they explode with yarn guts but can be put back together like a jigsaw puzzle. I used an I/R led to make the pumpkin trackable too so I could project a face on it :) biluminal.com/2019/10/29/infrared-tracking-projection/
Would you mind explaining that setup?
Sure, it's a somewhat complicated project as a whole, which part would you like me to explain? I used a cheap L298N stepper controller from amazon and a stepper that matches it. An arduino nano serves as the brains, i used 2 4.5v AA holders for power (in series to make 9v), to keep the profile low, and a very common serial-to-dmx module to receive signals from my light booth software. I'd be happy to share code, wiring, whatever you need.

wltd.org/blog_images/arduino_dmx_bb.jpg this shows how you wire up dmx to the converter, you can connect to any serial you want on the arduino. The ground path is wildly redundant in the wiring example here, you can just connect XLR1 to ground on the converter to both DE and RE pins to keep the converter active, i always do, you dont need 5 wires going to a breadboard.
