Favorable are displays that make you think of a clock instantly like the one I got with 4 number digits and a digit for the dots. You wanna find a display that is suitable to be turned into a clock, something generic. So one of the first questions of course you might ask is where you can get a VFD that you can turn into a clock. Datasheet of LM2577T and R90 note on schematics added. Initially it was 50k, but I've corrected it to 25k. Just a high school student fascinated by all that. Note that I am neither an electrical nor a software engineer. The circuits have been tested over and over again by me but I still can't guarantee that they are free of goofs and/or errors.

Great, let's get started! The first one shows you how VFDs look different compared to LCDs and the second one shows how your clock could look like after assembling. Look at the pictures above that I took if you haven't seen how VFD displays look like yet. I'm not a native speaker - just for you to know if you're wondering why some sentences might make no sense at all.
This is my first instructable here, showing you how I have designed built my clock and how you can build yourself exactly the same or a similar clock that utilizes the VFD display. That's why I decided to write this Instructable about a clock based on this technology. Vacuum fluorescent displays look really kinda fancy and cool to me, I really love the blue-green color.
Used to replace Nixie tubes way back in the 1960s, they can be found in many of our consumer electronic devices. These displays have a characteristic beautiful bright blue-green colored glow in common: These are so called vacuum fluorescent displays ( VFDs) with outstanding brightness that look pin sharp. Do you (still) remember the display of your old CD player, HiFi system or car radio? Have you ever noticed the displays used at your local supermarket that shows you the scanned item and the price of it?
