This week on the blog, we featured forums user HarpDude’s impressive “String Car Racer” project.
Back in the 1980s, my college-aged brother designed a simple motor+battery car that raced along a string between the birch tree and the street-side power pole.

The primary goal was speed and stability. The car ran at full speed until it found the end of the string — then you either had to be there to catch it or be prepared to repair it before the next time trial. (read more)
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.
