Retired Software Engineer with too many interests to ever be bored. Current project: "Raising" my robot, Carl, based on the Dexter Industries GoPiGo3 and Raspberry Pi3B. Former projects: Upgraded, then reverted, my 18 year old RugWarrior Pro robot with Raspberry Pi 3B (plagued by "health" issues: too many connectors, electrical noise, lazy mechanical design, too few encoder counts/rev, non-RTOS?, dead RPi SPI CE0_0 pin 24 line.) ©
