My obscure interest: Vacuum Fluorescent Displays

[N2IXK]

That would explain the low voltage. A filament will draw much higher current in air than in a vacuum, at least until it burns open....

Hey, I got a replacement VFD off of eBay for $25. It was for a CT-F800, but it looked like the same part and I took a chance. It was the correct part! It included the control board and everything, so I just hooked it up and screwed it in place, and it worked perfectly first time. Now all I need to do is re-belt this deck and then adjust it with my test tapes, meters, and signal generators, and it'll be good to go.

awesome you got it fixed. I got enough VU meter style VFDs laying around here to choke a horse. Even the one you needed. Anyways...

Here is my latest project that I have been working on:

I have a whole crate of these I got from a contact out of the Ukraine. I am designing a "retro" audio spectrum analyzer using individual VFD tubes.

And... Here it is. First power-up after assembly, but before any code is written yet for the MCUs.

That looks awesome. I really like VFDs.

I'm curious.
How often do people approach you inquiring about your sources?
I got an Itron alphanumeric display here I've spent two years trying to find a replacement for because the evacuation nipple broke off during rough handling.

[mbates14]

Almost never. Usually its eBay.

What is the part number/pic of it? I may have it.

Ooohhhh nice display. I'd like to get one myself somehow.

Two layer display handles more information.
It also creates three-dimensional appearance.

[mbates14]

Umm. I dont think you are understanding what I mean, you missed the word "particular" in my last post. I know WHAT it is, and how its designed. seen many of them. So I will re-iterate: I am just curious where to find THAT PARTICULAR display.

Some day I will get around to making something with these DT-1704Bs. I love that there is no backing to the digits, not even a sheet of mica.
