macro_GOAT
The successor to the Disarray Desnarler: a custom macropad built around an RP2040-Zero with a 16-LED WS2812B array, hot-swap switches, and up to four optional EC11 rotary encoders.

Hardware Projects
Macropads, noise makers, espresso hacks and other things that blink or buzz.
Disarray Desnarler
A solder-it-yourself macropad that runs on an RP2040. It runs QMK, comes with 4 keys and a fader and looks cool on your desk. Built with Hillary and Julia.
Gaggia Classic Scale Mod
A scale built into the drip tray of a Gaggia Classic that controls how long the espresso shot pours. Load cells under the tray feed an Arduino Nano via two HX711 amplifiers; a rotary encoder sets the target weight and tares the scale. Inspired by the Gaggiuino project, whose 3D-printable load cell mount it uses.
RGB LED Controls from a Vintage TV Panel
Workbench lighting from a wrecked tube TV found on the street: its brightness, contrast and volume slide potentiometers now dim the red, green and blue channels of an LED strip via 555/556 timer PWM. Housed in a 3D-printed case, with the LEDs hidden in aluminium tubes behind milky glass. Schematic based on Lb_20's instructions.
