Here's an old picture of the clock's electronics. At this stage of development, I had a low-insertion-force socket plugged into the real IC socket, so that I could pull & replace the PIC for software updates without wearing out its pins or the socket. The LIF socket is about 1/2" tall, preventing the two boards from being folded into their final right-angle configuration.
Most of the components on the left edge of the main (blue) circuit board, composing the power supply, were fried when I once accidentally plugged the PIC in upside down, and have been replaced since this picture was taken. (The PIC survived, of course - they're tough!)
