An account of what I found when I returned to the problem of precision timing nearly twenty years after I first worked on it, and asked the question: "what can I do with a $4 microcontroller?"
A wave of nostalgia motivated me to try building an accurate frequency counter using an inexpensive microcontroller. I think I got there... what do you think?
Last year I made a GPS enabled Christmas decoration and I just got round to writing about it. There was a good reason.... I promise.
