Thanks to @rpilocator I finally acquired a Raspberry Pi 4. Not sure what I want to build first. I'll probably just round up all the loose sensors in the junk box , wire them up to GPIO pins and write values to a Node-Red dashboard.

Or, I have a "robot" chassis, motor driver boards, etc. in the junk box. Maybe a desktop rover.

Or, I have a laser module, a couple servos and a new cat. Maybe a cat distracter to keep him off the keyboard.

Or, maybe the community has some ideas for Teach Yourself Python The Hard Way™
