Event moved to February. Please check back regularly for updates.
We last had a class featuring these VFD displays back in 2011. These Vacuum Flourescent Displays are series of vacuum tubes that show letters or numbers in a bright green or blue.
Akafugu has found a number of uses for VFD displays, and is providing a workshop at THS for soldering and programming them.
The VFD 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.
Two display shields are available, one using four numeric VFD arrays and one using alphanumeric.
