Blog about my diy electronic project s.
Vfd display project.
A beginners guide to adding a vfd display to your project or how to make use of all those cold war era russian tubes you bought on ebay w k fay 01 05 2018 at 01 16 this is a simplified down and dirty explanation of how to get these tubes running no frills cheap and cheerful lets get it done approach.
I bought the vfd at american science surplus when visiting a friend in chicago.
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.
This is a straight up explanation of how to add a vfd display to your project arduino microcontroller cmos whatever your game may be.
Initialize vfd display using arduino in this article i will describe how to initialize display from a faulty dvd player.

I think it is helpful starting off by telling you how a vacuum fluorescent display works.
Tinkercad will do the work here.
My vfd display project in 2004 i built this project around a vacuum fluorescent display vfd.
A bit of theory.
The rest of the electronics.
It is clearly designed for a piece of consumer audio equipment with tape and cd players.
Vacuum fluorescent display vfd from a dvd player controlled by avr mcu.
Inside the vacuum glass package of the display a tungsten filament is located above the anode segments.
If you know what an iv 11 or an iv 3 is then this is for you.
You may find one in your car dvds radios casette players etc also there are may kinds of vfd display modules available.
The last part of this project is an enclosure of course which will be 3d printed.
A simple driver for vfd displays.
It is great if you already how a triode vacuum tube works the vfd itself actually is a triode.
Hacking the vfd display the hard way.
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.
Vfd displays have been replaced by the new display technologies today but the quality of display a vfd gives is unbeatable.
And so this code was born.
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.
There s a lot of power management involved because this project requires quite a few power rails.
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.
