The story is that he’s making some controllers for quad copter motors so he wants to dabble with motors and motor controllers in a less demanding environment for a while.
Then he’ll take what he’s learned and apply it in the helicopter environment.
I think that’s a great methodology. Plus I’m sure he’ll come up with a really cool drawing robot system!
Perhaps I’ll adopt these motors!
Here are some pictures of his DIY arduino, motor controller and motor!
