Wire up your RGBW LED strip to Wi‑Fi with ESPHome! This 12 V controller drives four PWM channels—R, G, B, and W—using a simple ESP8266 board. Ideal for Home Assistant, perfect for ambient lighting, and totally local.

Recreate a Philips Hue-style smart lamp using ESP32, RGB LEDs, and separate warm/cool white strips. Fully controllable via IR, rotary encoder, and Home Assistant – with effects, brightness, and presets powered by ESPHome.

Turn any wired doorbell into a smart Home Assistant trigger! This PCB uses a D1 Mini and optocoupler to detect the bell press directly from the existing transformer, no additional power needed. Fully isolated and ESPHome-ready—just wire it in and go.

Turn your FPV drone races into fully automated events with this lap timer system! Using Arduino/RX5808 modules per drone channel and a Raspberry Pi running RotorHazard, it logs lap times based on 5.8 GHz signal strength. Easy PCB-based setup with jumper-configurable IDs, I²C connectivity, and full documentation — perfect for racers and event organizers alike.

This project delivers crisp and reliable stair lighting with motion-triggered LEDs – no fading, no delay. Designed to handle up to 16 steps, it reacts instantly to movement using PIR sensors and can be configured for night-only use, sensor types, and output timing. Simple, effective, and 100 % standalone.

Bring your staircase to life! This motion-controlled PCB lights up to 16 steps with smooth fade-in and fade-out animations. Configure sensor type, delays, night-only mode, and animation behavior – no app or cloud needed. Fully documented with schematic, layout, and ready-to-use firmware.

Transform your staircase into an intelligent light show! This DIY RGB stairlight uses an ESP32 and WS2812B LED strips to animate each step as you walk – triggered by motion sensors at the top and bottom. It’s fully programmable with ESPHome and integrates seamlessly into Home Assistant. All logic runs locally, no coding required. You can customize animations, colors, speed, and even add idle effects. This project is the ultimate smart home upgrade – practical, stylish, and entirely your own creation!

Build your own WiFi-enabled RGB clock using a Neopixel ring and ESP32 – no programming needed! Powered by ESPHome and designed for seamless Home Assistant integration, this project displays the current time using colorful LEDs for hours, minutes, and seconds. Whether you want a smart wall clock or a glowing desk centerpiece, this build brings together DIY flair and smart home functionality. Everything runs locally, is OTA updateable, and fully customizable through YAML – the perfect project for makers and smart home fans alike!

Power your outdoor electronics with this compact and smart 18650 solar charging PCB!
