"I used†breadboard†which could be soldered to and rats†nest†wiring†for the electrical connections. The headphones and high voltage†batteries†were put on the outside as I ran out of room inside the case.

VFD tube is a turquoise colour rather than the blue in the photo, also the†camera†had trouble†with getting an image of the bars so that's the best image I could get. There's also an image of it with no input being fed in: that image is the one that has the red number†visible. The red†numbers†are not in the other images because this thing eats batteries.
