Lots of things have happened with the keyer. I bought rotary encoders and had boards made and populated one and it works like a champ. Only one small error on the board, and it's in the silkscreen so I'm going to ignore it, although you can see it in the photo above. So, if you have an interest, how can you get your own keyer?

Well, start at OSHPark and get yourself some of the boards:

The source for the firmware is on Github

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.

A couple of years ago, I wote about a new keyer I was working on. What I meant by "working on" at that point was the software. I got a ways into that project and then essentially no farther. Life intervened and I got interested in other things and ran into some issues that I couldn't immediately overcome and a dozen other wimped-out excuses. So, it might come as a shock, assuming that there's anyone left who is paying attention, that I've not only continued to work on this project, but have actually made progress.
