This is Mover3D. A 3D printed, moving light, using the industry standard DMX-512 communication protocol for lighting control. Thus, it can plug in to any standard lighting control console, creating the ultimate lighting desk toy.
Mover3D features full RGBW color mixing and 180° of pan and tilt.
This project was designed to be as inexpensive and easy to make as possible, or with whatever parts I had available (hence the quite overkill servos).
Quick warning. This is what I would consider an ADVANCED project. There are many elements to this project which have proven to be a bit of a pain. Just something I thought should be mentioned.
Here is a link to the Instructable which details the assembly of Mover3D.
Links where available. These are what I used, but others may work. Just to note, some of these come in sets, but only 1 or 2 may be required.
