Stepper Motor Controller with H-Bridge

A lot of precision controlled elements in the world are moved using stepper motors. Stepper motors are pretty complicated when compared to simple DC motors. This complexity is where their precision originates. And in order control something that is complex, you need a controller that is also complex: an H-bridge circuit board.

Drawing Machine, Part I

For my final project, I’ve decided to continue with the idea of a drawing machine, but with a slightly different … More

Animation is Hard

The key takeaway from this week’s assignment: stop-motion animation is hard. 

Orbital Sketch with Grid Filter

Iterating on the previous Orbiting Bodies sketches I had made, I tried to see if there was a more interesting way to display the movement of the particles. What I ended up with, was a grid of circles that respond to the proximity to the particles.
