Online Digital Clock with glass nixie design. No lag

A smart voice-controlled multimedia system where the UniHiker K10 triggers Bluetooth keyboard commands on an ESP32 to control media playback, volume, and navigation hands-free.

A simple motion-detection system that changes the RGB LED color based on movement detected by the K10’s AIRecognition module.

eBUS Adapter Stick C6 is a reduced size version of previous highly demanded eBUS Adapter Shields and provides an interface to a 2-wire eBUS with galvanic isolation for enabling communication with an eBUS enabled heating, ventilation or solar system. With a size of 42 x 16 mm it is way smaller than the previous Shield versions, but still supports an USR-ES1 module being plugged onto it for having Ethernet access. Even better, with the upcoming firmware version for the ESP32-C6, it automatically scans the heating components and makes all data available via MQTT to e.g. Home Assistant with auto discovery of entities.

In this video, I demonstrate the simplest way to build an advanced, keyless security device using the CrowPanel 1.28-inch-HMI ESP32 Rotary Display. This module is a game-changer for DIY electronics because it integrates a touch screen, a physical button, and a rotary encoder into one sleek unit.

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.

A fully functional digital stopwatch built on the UniHiker K10 that uses onboard buttons to start, pause, and reset time with live display updates on its LCD.

A simple face-enroll and face-recognize system using the Unihiker K10’s built-in camera, RGB LED, and AIRecognition module.
