A miniature race car is balanced precariously on a single pulley, speeding between two trees on a narrow zip line — will your car win the race?
The Basic String Car Racer is a simple project that consists of a battery, pulley, a reclaimed motor, and a bit of fence wire. The original string car was made from repurposed parts and materials found in Grandpa’s basement workshop. This version uses more commercially-available parts, but could be hacked with parts gleaned from old DVD players, for example. What modifications and improvements would you make?
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.
