Pocket sized digital pets are really cool but pretty rare these days. Hackaday.io user NanoCodeBug thought it would be fun to make one. Paw Pet is a pocketable digital pet using an ATSAMD21 and Sharp memory LCD for long battery life.
It can run for two weeks on a pair of mere AAA batteries, and possibly more given a sufficiently polished firmware. The hardware has some serious potential, with the gadget’s platform lending itself equally well to Arduino or CircuitPython environments, the LCD being overclock-able to 30 FPS, mass storage support to enable pet transfer and other PC integrations, a buzzer for all of your sound needs, and an assortment of buttons to help you create mini-games never seen before.
You can see the project on hackaday.io, the code on GitHub and more in the article on Hackaday.
