Bucky is a very food motivated cat with a special talent for acting like he hasn't been fed. With miscommunications between five roommates, he was routinely tricked us into extra meals.
This simple tracker helps keep his meals straight. Press the button after feeding him and the display shows when he was last fed and when his next meal is.
A microcontroller, a small OLED display, and a button are all housed in a 3D printed enclosure mounted right by his food station.
