You may find one in your car dvds radios casette players etc also there are may kinds of vfd display modules available.
Vfd display project.
I bought the vfd at american science surplus when visiting a friend in chicago.
It is great if you already how a triode vacuum tube works the vfd itself actually is a triode.
Vacuum fluorescent display vfd from a dvd player controlled by avr mcu.
I think it is helpful starting off by telling you how a vacuum fluorescent display works.
The last part of this project is an enclosure of course which will be 3d printed.
Dvd player vcr and other consumer electronics use vacuum fluorescent display vfd for displaying different information and we can can control it using arduino.
The vfd panels from the back.
This is a straight up explanation of how to add a vfd display to your project arduino microcontroller cmos whatever your game may be.
A vfd usually works in a multiplexed fashion like a 2d matrix with x and y axis you need to heat up the filament the cathode you see those thin wires in front of it connect the ground on that filament as well a positive voltage to a grid control grid one point of the x axis and again a positive voltage on a segment pin the anode one point of the y axis at.
If you know what an iv 11 or an iv 3 is then this is for you.
Blog about my diy electronic project s.
Library for interfacing avr microcontrollers with et16312n vfd vacuum fluorescent display driver i had a broken philips dvp5960 dvd player and i thought it s a good idea to salvage and use the vfd display in some project.
And so this code was born.
Initialize vfd display using arduino in this article i will describe how to initialize display from a faulty dvd player.
It is clearly designed for a piece of consumer audio equipment with tape and cd players.
I will create a proper motherboard for the project but for now everything is wired to some protoboard that is just enough to make the display work.
There s a lot of power management involved because this project requires quite a few power rails.
Vfd displays have been replaced by the new display technologies today but the quality of display a vfd gives is unbeatable.
If you have ever wanted to know how these things work then read on.

A simple driver for vfd displays.
My vfd display project in 2004 i built this project around a vacuum fluorescent display vfd.
A bit of theory.
The bit of plastic in red will be screwed onto the pcb and help maintain the vfd tubes aligned at fixed positions.
The rest of the electronics.
Hacking the vfd display the hard way.
Inside the vacuum glass package of the display a tungsten filament is located above the anode segments.
