There are those who reckon the humble bowl of breakfast cereal to be the height of culinary achievement. Look askance if you must, but cereal junkies are a thing, and they have a point. The magic comes not from just filling a bowl and adding a splash of milk, but by knowing which cereals to mix together.
Who needs all that fussy mixing, though, when you can automate and customize your cereal dispensing chores? That’s the approach [Kevin Obermann] and [Adrian Bernhart] took with their Cereal Dispensing Machine, even if they went a little further than necessary. Laser-cut plywood forms a four-station carousel for off-the-shelf dry-good dispensers, each of which got a stepper motor to replace the wrist-twisting. The original motors were a bit too wimpy to handle the more rugged morning selections and were eventually upgraded to gear motors. The platform that supports the dispensers also holds all the electronics, including an ESP32 to run everything and host the web app needed to choose your poison. Plus RGB LEDs, because breakfast should look like a rave. Sadly, the team ran out of GPIO pins and were unable to run the peristaltic pump needed to add the milk. There will always be version 2.0, though.
If cereal isn’t your automated breakfast of choice, we understand. Perhaps a more [Wallace] and [Gromit] style breakfast machine would do, or a robotic peanut butter sandwich any time of day is a treat.

Wars generally increase innovation as the opposing sides try to kill each other in ever more efficient ways. Even the soft war waged daily between felines and their human servants results in innovation, to wit we offer this armor-plated automated cat feeder.
The conflict between [Sprocket H.G. Shopcat] and her human [Quinn Dunki] began with a thoughtfully provided automatic food dispenser. Like human vending machine customers who witness a just-purchased bag of Cheesy Poofs dangling on the end of the dispense auger, [Sprocket] learned that the feeder would dispense a few fishy nuggets when nudged. [Quinn] embarked on an iterative design process to control [Sprocket]’s off-schedule snacking. Fastening the feeder firmly to the floor, and adding obstructions to prevent her from pawing up the dispense chute — nothing seemed to stop the clever feline’s raids. [Quinn] then pulled out all the stops and whipped up a [Sprocket]-safe enclosure for the feeder from 1/8″ plate steel and copper. This seems to have put the cat back on the straight and narrow, and it doesn’t look half bad either.
All kidding aside, [Quinn]’s approach to this problem is pretty instructive. Careful observations informed several cycles of reasonable modifications until it became clear that only the most extreme solution would work. There’ve been tons of cat feeders here before, from the simple to the complex, but we think all would fall prey to the clever [Sprocket] without a little up-armoring.
