BCDClockLite

The BCDClockLite kit is an educational electronics project that teaches binary numbers, digital logic, and timekeeping through hands‑on assembly. By soldering components onto the PCB and interpreting binary LED output, learners gain practical experience with circuit construction and understanding how digital systems represent and process numerical information.

With a minimalistic / brutalist architecture look the display is comprised of 20 multi-coloured LEDs driven by an ESP32C3 supermini. The clock is configured via a simple web page interface accessible from a PC / Mac / iPhone / Android / etc.

Sold as an easy build kit - soldering is required. The manual and build instructions can be found here.
