Just pulled this out of a scrap box... looks like fun to play with... A

Noritake itron CU24025 - 24 x 2 https://www.noritake-itron.jp/eng/products/module/cu-u/ss/se-cu24025-uw1j.pdf

Need about 200 mA @ 5V to power
HD44780 compatible

They still sell them about $50-75 - hope this one works... I love the way these look... not very efficient but fun.

 

VFD in my vocabulary means a Variable Frequency Drive!
Max.

 

@Wolframore Those things work really nice. Here's a short form datasheet and full manual for it. They power really nice with one of the Simple Switcher power supply circuits.

 

I know it took me a while to get vacuum fluorescent display....

thanks John that's exactly what I need... looking forward to playing with it...
