I spent some time looking at SVG/PCB program and really wanted to make something with it. Perhaps this week. But had trouble learning the program without an end objective. So I started thinking about what this board would "do"? Instead of doing things I wnanted my board to represent a thought path around math, synchronization, order and patterns. What would be the simplest setup for two (or more) microcontrollers that would make a light flash, a sound chirp (like crickets) that would eventually synchronize through software control.
I had some great conversations with folks at the Harvardsite and explored first whether we could get the xiao SAMD21 chip to find a persons heartbeat (through wrist pulse) and we soldered some pins on the chip and attached a wire to pin PA4. A program was written (by Quentin) to attach numbers to the amount of contact "felt" by the wire and we were able to deliniate contact but there was too much noise to find a pulse.
Went simpler and started designing boards on paper with pen and ink that dealt with synchronicity in form and function.
And others that were about an uneven relationship between form and function
