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! 🙂
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
