I've been building some electronics for the top cover of my computer gauntlet. Here's the video. I'm driving the lights with the same Arduino board and MAX7219 driver, but I've arranged the lights differently. There are just two digits, not four, and then there's a spinning bar in the square opening. I also sequenced a set of eight blue LEDs in the long narrow window, and I kept the same blue lights that blink in the triangles.
I'm planning to connect this to the base and drive the existing countdown timer plus the top cover from the same Arduino board. I'll let you know how long the batteries last after driving 82 LEDs all night.
