I now find myself one of the maintainers of [ profile] amateurradio. Please feel free to take this as a source of inspiration to get your ham radio licenses and then join the community.

I spent some of this weekend operating in a ham radio contest. I couldn't operate for more than a few hours, what with the wife and small child and other commitments, but it was fun. What turned it into an honest-to-goodness nerdgasm was that I wrote1 the software that I used to keep my log and to calculate the score.

1For the Mac, using Objective-C and Cocoa.

It was a busy weekend, and it involved driving to Philadelphia for a couple of events, of which more later. But I went on the air for two hours before bed on Friday night (a contest was going on) and made contacts in Tobago, the Canary Islands, Jamaica, France, Spain, Honduras, The Gambia, and Turks & Caicos.

I got a signing bonus with the new job. A lot of it is going to bills, but I did buy one of these, and I'm almost done building one of these. I don't think I've been on HF since college, and I'm really looking forward to getting back on the air.

The bad news is that I can't sleep because, if I try, I'll drown in my own snot.

The good news is that I have taken advantage of the time and built a circuit with a 7805 voltage regulator, a 555 timer, and a 74AC109 dual J-K flip-flop. I think it's too cool for words, solely because it works. (Here, "works" means primarily that nothing has caught on fire and secondarily that various LEDs flash off and on when they're supposed to, thereby indicating that the signals are going where and when I want them to.)

It is 3 A.M. A certain small person does not understand that he's supposed to be asleep instead of sitting on the sofa watching the Wiggles. I keep trying to remind myself that he's sick and that he might therefore have trouble sleeping, but I'm having only mixed success.

During waking hours, I am in heavy geek mode, simultaneously obsessed with two projects. I've put a lot of time into a set of Java classes that make it easy to dump debugging information to a log file or to a web page. I also remain fixated on this computer and similar projects, and I have started playing with digital logic ICs and reading books on processor architecture. Oh, yeah, and I have a job and a family.

I am currently fascinated with this site. Someone please stop me before I start ordering parts.

Although I really, really do want a computer with a front panel covered in toggle switches and blinkenlights.
