Kerry Wong documented his VFD filament driver built:
I recently salvaged a vacuum fluorescent display (VFD) from a piece of old test gear. The VFD is a 13 digit 7-segment multiplexed display and I thought it would look great in a custom digital clock or something similar. While it has the model number FUTABA 13-MT-54NA, I could not find any information on the internet specifically for this model.
Of course, before I could put this vacuum fluorescent display to use in my final project, I needed to first build a driver circuit to drive this display.
