The VFD Modular Clock is a clock based on old-fashioned VFD Display Tubes.
VFD is short for Vacuum Flourescent Display. A VFD display is typically green or blue, and emits a bright light with high contrast. VFD Displays are often found in car radios.
A VFD Display tube looks like an old Vacuum Tube, the predecessor to the transistor. The inside of the tube contains segments that can be lit up to form numbers and letters. Most tubes contain segments for one digit, and several must be stacked together to make a complete display.
The clock itself is modular, it comes with a base board, which is powered by an ATMega328p microcontroller and contains a high-voltage VFD driver that is used to light up the display shield that sits on the top board.
This version of the clock comes with 4x alphanumeric IV-4 tubes.
We are currently shipping version 2.0 of the clock, which includes an upgraded base board with Arduino-based firmware and built-in Four Letter Word generator.
