A clock that hears the time whispered from across the room.
Last time I had to stop on the filter design because lunch got in the way. And then many other things (read: other projects at more exciting stages) got in the way. But finally I am back, and actually some progress has been made in the meantime.
I didn't know what exactly I was getting into when I came up with the idea to split 6 signals across the 4-20kHz range. Turns out I am getting into trouble, but that would be a spoiler since my writing is running behind the actual design work... Yes, I am setting up a cliffhanger for stuff that is not even in this "episode" 🤣
An analog clock that receives time from my PC, with no microcontroller and no binary until the very last step, or maybe not at all!? 😮 I was going to start it in the dark Prague winter, but math study wore me out enough that I need the distraction now. 💥
