The Sensor Watch started on a lark. @GregDavill had designed a SAM L22 calculator watch the month before. I loved the idea. A watch is bigger than a ring, but it’s eminently wearable. I chose to target the iconic F-91W. Same nine-pin connector, of course. https://twitter.com/josecastillo/status/1348474279952855044
