My obscure interest: Vacuum Fluorescent Displays

[mbates14]

Here are the few that I forgot:

the graphics VFD was a chip-on-glass one that I had gotten, no datasheet or pinout available, so i had to reverse engineer it myself. Although with the ghosting, I never did get too much further with it. My guess was it was a 3.3V VFD that I was driving with 5V.

Here is the 50+ russian VFDs that I had gotten.

Shown is the new control board I had developed for them, So i can control the tubes digitally. Unfortunately the project was sidelined becuase I used 2 ICs that are no longer available. the LM9022 and A6810.

Oh, and I cannot forget this gem:

Here is a set of GM VFDs that I re-purposed for use in a golf cart, digital cluster. It worked until the rain finally got it. lol.

I found out that these VFDs were used in the 2008ish era chrysler factory radios.

A few new ones added to my collection, AND a noritake VFD sample from noritake themselves, KS0108 compatible!

I have been at it again.

These Futaba displays are actually on ebay right now for a mere $2.50 a piece. So i got a few and built a circuit.
