Feeding Dogs over Twitch is Latest E-Sport Craze


The modern social-networking fueled Internet loves two things more than anything: pets, and watching other people do stuff. There’s probably a scroll tucked behind a filing cabinet at Vint Cerf’s house that foretells anyone who can harness these two elements will gain control of the Internet Ready Player One style. If so, we’re thinking [Tyler Pearce] is well on his way to ascending the throne.

In an effort to make the Overwatch Twitch streams of his betrothed even more enticing, [Tyler] came up with a way for viewers to feed their dog Larry by dropping a command in the chat. There’s a surprisingly complex dance of software and hardware to make this reliable and visually appealing, but it’s worth it as showmanship is important in the brave new world of competitive e-sports. We’re assuming that’s what it says in the issue of ESPN Magazine with the Fortnite player on the cover, but nobody at Hackaday would qualify for a subscription to it so we don’t really know for sure.

A server running on the computer provides a slick administrative dashboard for the treat system, including a running log of who fed Larry and when. There’s also a number of checks in place to prevent too many treats being dispensed in a short time period, and to keep an individual from spamming the system.

On the hardware side, he’s using two NodeMCU ESP8266 microcontollers connected to a local MQTT broker: one to handle the lighting and one to run the 3D printed auger that actually pushes the food out. The printed auger is powered by a standard hobby servo, and even includes an IR sensor to automatically stop spinning when it detects a treat has been dispensed. [Tyler] reports the auger works quite well, though does have a tendency to jam up if overfilled.

We’ve seen all manner of automated pet feeders over the years, even ones with their own email accounts. So it was probably only a matter of time until they came to Twitch. If you can install Linux with it, why not use it to feed your dog? Or somebody else’s, as the case may be.
