Absolutely wonderful! Is the lisajours system based on the analogue one published in the 60-70s book "Electronic Circuits Manual" by John Markus or is it your own software/hardware design? (it doesn't look like the analogue design is stuffed inside the case)
I'd love to build your clock - please say that you will make an affordable kit.... What more have you got hidden in your drawers that is equally wonderful as this clock? Now that the YouTube age is here there might be more to show from your drawers!? During my studies in the mid 80's we made a similar clock in a course about VLIW processors (Very Large Instruction Word) where we also used lisajours to display the numbers on an oscilloscope screen. I remember that debugging the code for the lisajours on a processor that we had designed ourselves took many more hours than we thought at first, it actually took months, this as we had to write the code for all of the maths formulas, and debugging those were not easy. We also thought about doing the same clock on the "one instruction" processor design but we did not have time to finish it during the course. /Martin On 15 Feb, 08:42, David Forbes <dfor...@dakotacom.net> wrote: > Folks, > > I am going to be in San Francisco this Saturday giving a brief talk at > the Exploratorium about how I ended up making watches. > > As a preparation for this talk, I have resurrected my Scope Pocket Watch > that I built ten years ago.
