I'm building a pair of belt gizmos for my son and myself. These are scratch built, not a kit. I had originally planned to use 10mm plastic test tubes with 7 segment LEDs for the display. But after some research, I realised I could use real vfd tubes using a 9v and AA battery. So I purchased 24 used bb8-3 tubes off eBay. Here's the results so far.
It took 2 months for the tubes to arrive. And the first tube I tried was dead. The wait and effort was worth it. The display is static. I'm still waiting for a pair of 4017 circuits to animate this.
