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 is an affordable weather station for various applications like smart agriculture, smart city, solar plants, construction site, etc.

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!

Power your outdoor electronics with this compact and smart 18650 solar charging PCB! Designed for low-power IoT projects like ESP-based sensors or automation nodes, this board combines a TP4056 charging module (with integrated undervoltage protection), a TPS61023 5 V boost converter, and two optional switches for flexible power management. The board runs from up to five 5V solar panels and supports one or two 18650 Li-Ion cells. Ideal for garden sensors, smart weather stations, and other mobile DIY projects.
