After getting intimate with some of the finer points of NTP yesterday, I've spent the last few hours writing code to drive a 7-segment LED display. It's been a while since I've fettled one of those, but it's a vital aspect of the "1980s mission control"[1] aesthetic I'm going for with barakta's new alarm clock. (Needless to say, it will also feature a large red 'abort' button.) Freakishly, it worked first time.
