My family had three cats, all with different feeding schedules.
After seeing the price of commercial automatic feeders, I set
out to design my own. I first experimented with different ideas
for the sensing and to ensure the electronics would work as
expected.

<p style="padding-top: 1em">
I ended up settling on using an ESP32 WROOM microcontroller and
the proximity of a bluetooth tag from Blue Charm Beacons to
trigger the opening and closing of the door. I wrote the Arduino
(C++) code to manage the logic and it is hosted on my

I then designed the enclosure and door mechanism in CAD to
validate the mechanical interactions. Explore the CAD model below:

Next, I started prototyping and manufacturing the physical design
using plywood, aluminum L-channel, and acrylic before assembling
the mechatronics into the enclosure:
