Open Sesame

I have been busy over the last few months working on a Wi-Fi controlled kennel door opener for my dog. Her kennel is the basement where it is cool and quiet, and it would be convenient to open the door without having to walk downstairs.

The brains is a Teensy LC that gets signaled to open the door over Wi-Fi and opens the door using a servo. After breadboarding up a prototype, I designed the PCB in Kicad, used OSH Park to fab it, and designed the servo mount and arm in Sketchup which my coworker 3D printed for me.

I'm still assembling the boards and working out what I hope are the last few bugs. I'll post more details when it is complete. In the meantime you can see the SW, HW and mechanical design files on Github.

There are comments.
