The must-have toy of a couple of decades ago was the Tamagotchi, a virtual pet in an LCD screen on a keyring, that demanded your attention and which would die were you to neglect it. Fortunately it had a reset button on the back through which it could be resuscitated, but even so it lacked a satisfying tactile experience. [Nadine] has done something about this with her Tamagotchi-style Tribble, an anthropomorphic ball of fluff that demands attention and purrs when it receives some.
Inside the ball of fake fur is an Adafruit Circuit Playground with a capacitive touch pad and a haptic motor. After a random time with no attention it “cries”, and its owner strokes it, after which it responds with a purring vibration. It’s quite cute as you can see in the Twitter video below, and fortunately it won’t multiply and fill up your starship. We wonder whether a small resistive heater to give it a body temperature would complete its appeal as a virtual pet.
Given the popularity of Star Trek TOS among Hackaday readers perhaps it’s surprising that we don’t see more Tribble related projects. They have made a notable appearance as a DEF CON badge though.
