Ziploc Storage and Fish Feeders

Two smaller projects to share. The first is a simple storage solution for ziploc bags. My wife requested these because the original cardboard boxes didn't fit in the kitchen drawers well.


They fit perfectly and look nice.


An an unrelated note, my son recently got a betta fish. He cares for the fish very well, but I worried about how to feed him (the fish) when we go on vacation (and also my son, I guess). I put together a simple fish feeder that can be attached to the side of the tank.

A small LED blinks to let you know how long until the next feeding occurs. The design consists of a PIC16F15323 microcontroller, a cheap 28BYJ-48 stepper motor, and a homemade PCB. The blue mechanism is 3d printed PETG, which behaves well if it gets wet.
