The VFD tube is the display for the clock. It has 9 digits, 8 of which are standard 7 segment plus dot displays. The leftmost digital has only a * and -. Instead of having 60+ connections for each segment, the display is gridded out so that you can only turn on one digit at a...
Have you gazed longingly at large TFT displays - you know what I'm talking about here, 4", 5" or 7" TFTs with up to 800x480 pixels. Then you look at your Arduino. You love your Arduino (you really do!) but there's no way it can control a display like that, one that requir...
