Oh that's interesting, thanks. I'm not familiar with DragonFrame the software, but I imagine it's something that does 3D motion control for animators? I find it interesting that there doesn't exist (or that the author didn't use) an open source alternative for this box.
Hey, I made this! There are Arduino solutions for motion control with Dragonframe, but I opted to invest in a used DMC16 because it can handle in/out triggers (which I tapped into with my custom control box), it has DMX out for lighting control, and it does motion control signals faster than Arduino can, and it's all in a nice package that I can rack together with the rest of the gear. It might be a little overkill and I'm sure a custom solution could work, but I'm usually more interested in results than process, so I tend to take prebuilt approaches when practical.
