I survived ApolloCon just fine, and I'm more energetic than I can remember being, so I have started to work on projects again. I have too many projects, but I still want my memory keyer to be finished, so I'm working on that.

A while back, I finished the board layout for the correct transistor pinouts, and I sent it off to OSHPark to be turned into actual boards. I also ordered parts. Last week I even found out what was wrong with my soldering iron (it wasn't set up right at the factory) and I fixed it. So, I was all set.

I've wanted a memory keyer for a long time, but they tend to be expensive and I don't work enough CW to really justify it. However, about three years ago it occurred to me that you could make a memory keyer out of an Arduino. (An Arduino is an amazingly cheap microcontroller board that some clever Italians designed. See, e.g. http://www.arduino.cc/ for more information.) Anyway, a while after I thought of that, I decided that I didn't want to spend a bunch of time designing the hardware and programming the Arduino.
