With the first final motor unit assembled, and the newly gathered knowledge about Eagle PCB it is time to work on the motor control unit.
For my automatic curtain project I’m currently working on the design of the motor driver PCB in Eagle. The stepper motor driver I’ll be using is the Pololu DRV8825. Unfortunatly, this device is not available in the Eagle library, so I had to make this part myself.
Exactly one year ago, I started my Annoying Dishwasher™ Project. With this project, my main goal was to silence the annoying beast for once and for all. Today, one year later, I continue this project to make some improvements by applying the knowledge I gathered in the past year.
