Virtual Nixie VU Meter — LCD Display

A compact variant of the virtual nixie VU meter using a 1.3-inch color LCD. It is designed to be mounted directly into a preamp or integrated amplifier chassis. The video shows the unit reacting to speech and music with the characteristic nixie-tube glow. The board supports both line-in and MIC input, and exposes a UART for firmware updates and mode selection. An optional GPS module can be connected to discipline the real-time clock.
