6.1
A DIY article details the NeoPixel Aura Clock, a compact battery-powered Wi‑Fi RGB clock built for under $10 using an ESP8266 microcontroller and WS2812B LEDs. The project uses NTP time synchronization, a custom PCB, TP4056 Type‑C charging, and a 3D-printed diffuser enclosure, enabling builders to reproduce a portable, addressable RGB time display with assembly and firmware guidance.
