USB‑C, hand‑solder desk toy that flashes an LED when it hears a sharp sound — a mic front‑end and a 555 timer fire a ~2.4 second "lightning flash."

A USB‑C powered, hand‑solder Morse code learning tool — taps on the capacitive touch pad like a telegraph key; an ATtiny85 decodes the dots and dashes, sounds them on the buzzer, and shows the message on a 5x7 LED matrix via the MAX7219.

USB‑C, hand‑solder desk toy that rolls two six‑sided dice — an ATtiny85 watches a light sensor and shows the result on a 12‑LED bar display.

USB‑C, hand‑solder countdown toy — an ATtiny84 drives a single 7‑segment digit and a piezo buzzer through a rocket‑launch countdown.

This tutorial details the setup of a Rust development environment on the ESP32C3 RISC-V microcontroller in under an hour, enabling the use of the Rust Standard Library ("std") as well as the MCU's Wi-Fi and Bluetooth capabilities.

This tutorial details how to use Rust's Vec and HashMap collections on the BBC micro:bit's ARM Cortex-M4F microcontroller in under an hour, enabling the use of the Rust Standard Library ("std").

Instalación y librerías personalizadas para display de 7 segmentos (8 dígitos) con el chip MAX7219 en Raspberry y Raspbian Estable

Per-key keyboard RGB for Clevo ITE 829x laptops. Userspace HID via hidraw — no kernel module, no DKMS. Should work for tuxedo, novacustom, originpc and any other clevo based laptops using this standard.

Light painting with a Raspberry Pi and an LPD8806 LED strip — a fork of Adafruit's demo with a CLI, image resizing and strip blanking.

Reverse engineering of the IKEA GETKÅL colour-changing LED string light: decoding its power-line data protocol (pulse-distance coding, 32-bit blocks, 12-bit colour, run-length zones) from oscilloscope captures.

This project is a scalable, web based LED control platform I developed for my fathers model railway buildings. The main goal was to easily control a few hundred LEDs (on/off, dimming 0% - 100%), grouping some together and randomly turning some LEDs or groups on or off to create a lifelike simulation.
