Several years ago Forrest Trenaman built a 25cc gas engine-powered RC boat. He concluded the sixth video with mention of a follow-up video to address some quirks revealed in the test drive, but that video never materialized. Regardless the 6-part build series is pretty informative and very impressive on the water, considering the low cost of materials (including a fixer-engine and generic plywood). Hopefully this inspires someone else to build a similar RC boat design if you’re interested in this sort of thing — in other words I’m bookmarking my own post to inspire some boat-building adventures! 🙂

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
