A common piece of physics lab equipment is a device called a “fan cart.” Perhaps you used one yourself when you were in high school of college? A fan cart is essentially a low-friction dynamics cart, commonly used to study motion, momentum, energy, etc., fitted with a motor and propeller or “fan.” The fan provides a constant force, which conveniently produces a constant acceleration. Fan carts are available from science lab supply vendors, but some are cheap, break easily, and lack features while other higher quality fan carts are sometimes expensive for science departments on a budget. I have designed a low-cost, programmable fan cart that fits in existing dynamics carts (most physics labs already have dynamics carts), and this Instructable describes how to make one.
Each Tuesday is EducationTuesday here at Adafruit! Be sure to check out our posts about educators and all things STEM. Adafruit supports our educators and loves to spread the good word about educational STEM innovations!
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.
