DMX Mini Moving Light First Assembly – Live Stream

With the shell 3D-printed and the PCB assembled, I went ahead and put together my first “completed” mini-moving light, live on camera:

It went fairly well – everything mostly worked and nothing caught fire!

There are a few mechanical and electrical takeaways for the next version, including:

  • Mechanical:
    • Ennlarge the hole for LED wires in the lower case
    • Make a brief instruction manual for myself of what needs to be assembled/installed/solder in what order
    • Hole for program/enable switch access
    • Fix tolerances on the tilt-servo/yoke interface
    • Lengthen the body to accommodate a heatsink for the LED star
    • Figure out mounting/hanging hardware
  • Electrical:
    • Increase the spacing between Pan and Tilt Servo pads
    • Order higher-current 5V regulator (1.5A 7805)
    • Select a new inductor for up to 1A of current
    • Select a new schottky diode for up to 24V
    • Combine the transmit/receive control lines onto a single pin of the Arduino.

But all in all, for a first assembly, even tripping over a couple of silly mistakes on my part, things went pretty well. Onward to V0.4.
