MSP430 VFD clock – Manhattan style

Daniel has a nice write-up about building his Manhattan style VFD Clock based on the MSP430G2553 microcontroller and the MAX6921: I know that and IV-18 based clock isn’t anything original. In fact, Adafruit used to sell a kit for this exact purpose. I don’t really care that it’s not original, because all vacuum tubes are […]

ChronodeVFD: Wearable Electronics VFD wristwatch

Johngineer wrote an article detailing the build of his ChronodeVFD wristwatch: 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, […]

A DIY vacuum fluorescent display driver

Kerry Wong posted an update on his vacuum fluorescent display driver we covered earlier: As I mentioned before, there are many driver chips (e.g. MAX6921, MAX6931) readily available for interfacing with VFDs. The driver circuit I am showing here is a bit more complex as it uses only the generic 74HC’s and discrete transistors. The basic […]

GIVEAWAY: Vacuum florescent character displays

This week we’re giving away 2×20 character vacuum florescent displays to three winners (2 each). It interfaces just like a typical HD44780 LCD, but the display uses blue-green VFD characters. VFDs are always very popular, but also very expensive. Pulls are the only affordable source we’ve found. Leave a comment on this post with a […]

Demo: Noritake Serial VFD

Edouard Lafargue let us republish his demonstration of a Noritake GU140x32-7002 Serial VFD screen (may prompt about a secure certificate). The Noritake VFD used here is a “Show and Tell” 140×32 semi-graphical VFD. This display has the big advantage of being able to display graphics and manage so-called ’user windows’, making it a good choice […]
