It is great if you already how a triode vacuum tube works the vfd itself actually is a triode.
Vfd display project.
The vfd panels from the back.
Initialize vfd display using arduino in this article i will describe how to initialize display from a faulty dvd player.
If you have ever wanted to know how these things work then read on.
Vfd displays have been replaced by the new display technologies today but the quality of display a vfd gives is unbeatable.
I think it is helpful starting off by telling you how a vacuum fluorescent display works.
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.
It is clearly designed for a piece of consumer audio equipment with tape and cd players.
The bit of plastic in red will be screwed onto the pcb and help maintain the vfd tubes aligned at fixed positions.
There are various audio related indicators at the top a 12 character 14.
A simple driver for vfd displays.
The rest of the electronics.
And so this code was born.
Blog about my diy electronic project s.

Inside the vacuum glass package of the display a tungsten filament is located above the anode segments.
This is a straight up explanation of how to add a vfd display to your project arduino microcontroller cmos whatever your game may be.
Vacuum fluorescent display vfd from a dvd player controlled by avr mcu.
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.
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.
There s a lot of power management involved because this project requires quite a few power rails.
You may find one in your car dvds radios casette players etc also there are may kinds of vfd display modules available.
I bought the vfd at american science surplus when visiting a friend in chicago.
Dvd player vcr and other consumer electronics use vacuum fluorescent display vfd for displaying different information and we can can control it using arduino.
Tinkercad will do the work here.
Hacking the vfd display the hard way.
The last part of this project is an enclosure of course which will be 3d printed.
A bit of theory.
