And the lights on the keyer go blink, blink, blink

The lights on the keyer all light up, but one

I've been working toward this for a while. Since I last visited the keyer project, I rearranged my workbench so my work area is larger. My computer, which used to share half the table of the workbench now covers the entire table, and I got my microscope out and went a little nuts with the surface-mount parts. Having finished that, there was no reason not to put the through-hole parts on the board, either. And now, well, a picture is worth 1000 words, right? One of the red LED's doesn't light, and I don't know why, but there will be time to figure that out later. Now, I have to get writing on the firmware, so I can use it to actually key a radio.
