A bit of theory.
Blog about my diy electronic project s.
It is great if you already how a triode vacuum tube works the vfd itself actually is a triode.
A vfd usually works in a multiplexed fashion like a 2d matrix with x and y axis you need to heat up the filament the cathode you see those thin wires in front of it connect the ground on that filament as well a positive voltage to a grid control grid one point of the x axis and again a positive voltage on a segment pin the anode one point of the y axis at.
