The ChronodeVFD is a personal project I’ve been working on for a couple of months. It’s a wristwatch built around the IVL2-7/5 VFD display tube. I originally purchased a few of these tubes to build a standard desk clock, but after playing around with them, I realized I could probably build a wristwatch too. The tube has a number of features which make it more suited than most Soviet-surplus VFDs for this purpose.

VFD Moduar Clock IV-4 6-digit by akafugu.jp:
This new shield design for the VFD Modular Clock is a variant of the original IV-4 shield, but with 6 digits. IV-4 tubes are Russian 16-segment VFD tubes, and can display numerals and the letters A-Z.
We’ve also designed a completely new enclosure for the IV-4 6-digit shield. It uses 2mm semi-transparent blue acrylic, and is designed to give a low-profile rounded appearance.
Creating a 6-digit IV-4 shield without redesigning the base board presented a unique challenge: The HV5812 driver used to drive the VFD tubes has 20 channels. IV-4 tubes are 16 segment displays, 20 – 16 = 4, so in other words the HV5812 driver can only support 4 IV-4 tubes.

Kerry Wong documented his VFD filament driver built:
I recently salvaged a vacuum fluorescent display (VFD) from a piece of old test gear. The VFD is a 13 digit 7-segment multiplexed display and I thought it would look great in a custom digital clock or something similar. While it has the model number FUTABA 13-MT-54NA, I could not find any information on the internet specifically for this model. Of course, before I could put this vacuum fluorescent display to use in my final project, I needed to first build a driver circuit to drive this display.

This is a project i designed a year ago but never built, because of not enough spare time. This month i found some free time so i started building it and i send the pcb layout for manufacturing.
All started when i received some IV-11 vfd tubes from an ebay seller i ordered from and i started testing and prototyping by first trying to simple light up the VFD tube.
A VFD tube works like a 7-segment led display with some small differences.
A) The Filaments. The Filaments exists to power the tube. We have to supply these two pins with 1.2Volt and nothing more (polarity doesn’t matter).
B) The Grid. The Grid is like the common anode of a 7-Segment LED display. So the Grid has to be pushed high at 60Volt (in these tubes) in order the segments to be able to light up.
C) The Segments. The Segments light’s up simple by pushing them high at 60Volt.

This is a quick tutorial on getting a VFD working with an Arduino (or Arduino equivalent system). VFDs are beautiful devices with a wonderful hexagonal mesh of wires and this lovely green/blue glow. Operating at around 5V, they offer a nice alternative to high voltage Nixie tubes, while still retaining a lot of the charm.
This tutorial will show you how to connect a Arduino-like device to a VFD display as well as a basic program to display text.

Summer of 2010 I picked up an Arduino board from adafruit and took some time to walk through all of the tutorials available with it. Since then I have spent most of my time on other projects including my bachelor’s. Recently I have obtained the Motor Party Pack, LoL Shield Kit, and a 20×2 VFD (Vacuum Fluorescent Display) to go with the original board so my interest is sparked again. I have found that the Motor Party Pack and LoL Shield have adequate instruction and tutorials, but the VFD is lacking in beginner level instructions to get started. As such I have decided to write a tutorial for the 20×2 VFD available through adafruit.
The adafruit VFD is made by Samsung and is model No. 20T202DA2JA, this is really unimportant though as adafruit is nice enough to link you to the spec sheets for both the module and the controller chip. What you would be looking for is the pin-out found on page 4 of the module controller sheet.

USB LCD/VFD Controller is a HD44870 based LCD/VFD controller via USB interface. The control command is compatible with Matrix-Orbital’s LCD module.So, you can use any MO friendly software to control this baby. Such as LCDC.The firmware are based on David Potter’s Serial LCD/VFD Display.Some features :this project uses a FTDI FT232BM chip as the USB bus controller,upports industry-standard LCD interface ,Configured for 16×2,20×2,20×4,40×2 LCD/VFD module,include hardware 19200-baud RS-232 input,the LCD/VFD can configured via commands.control with Microchip PIC16F873 MCU ,use 93C46 to store data.

This instructable describes how to mount a VU meter into a case of an old cd-rom drive and then put it into your pc.
On eBay I bought a bunch of VU meters based on VFD displays build in Russia. The displays where rather cheap and looked nice. I thought I’d give it a try.
When the vu meters arrived I realized that on all devices there was one transistor missing. To make them work again you need to “repair” the vu meter … don’t panic you can easily solder a substitute transistor onto the pcb.
