Cat Feeder Ensures Fed Cats

This DIY cat feeder checks whether a cat presumably ate the food, not just whether it was dispensed. [Jason] built it around a Raspberry Pi Pico W that monitors a weight sensor under the bowl for a drop in weight. An ultrasonic sensor beside the bowl ensures something cat-shaped was there at the same time. An early issue with the sensor emitting noise in a cat's audible range seems to have since been solved. The hardware has wireless communication and can log data, though like most cat feeders it only works for dry food.

The $8 Linux Computer (2022)

An $8 Ox64 RISC-V single-board computer can run full Linux, not a stripped-down MMU-less kernel. It has three different RISC-V cores, but ethernet, wifi and SD card don't work yet. Flashing it is painful: it must be programmed over UART, not USB, and DevCube crashes on Wayland so you need Xorg. A CH340G USB-UART dongle failed the handshake, so the author used an RP2040 (Adafruit KB2040) running picoprobe as a serial bridge, then had to modify bflb-mcu-tool's uart interface file to strip DTR/RTS handling before it would flash the M0 core.
