oh dear - i need to research

A project log for Locomatrix - 3D POV - a different approach

Let's use some rotary to linear movements to display things in 3D. I have no idea if this will work, but hey, I'm gonna try it anyways...

So the motor was definitely the wrong choice. Or may be not the best for a directly driven gear. I have to come up with a gearbox, speeding down a beefier motor to make it work. The arduino was underfed with power when the motor turned so there was no way to get a satisfying light show :( I'm going to replace the arduino with an attiny45 later, but it was easier to get started with this setup. For the time it moved, there was almost no friction on the 3D printed parts. Any Ideas?

Here is a video of it not moving but glowing, a sonic screwdriver and me saying "crap".

Can you power the motor separately for testing? It seemed like it worked well on the bench before you tried to control it with the Arduino.

  Are you sure? yes | no

there is no control by the arduino, they only shared the power line (raw in on the arduino). I had to order a new motor because mine started smoking and broke. I bought a 12V 13000 rpm motor which fits the mount and some gears I hopefully can glue to my gear.
