I saw these videos on the internet with people riding electric skateboard and going really fast. Well, I wanted to do the same thing, but those boards were 1500 USD, too expensive for me. My diy version only cost me 150$ that is 10% of the cost of the commercial ones! Granted mine is not perfect, it easily gets the job done.
Currently I get around 10 km of range at 20km/h, but the range can be easily upgraded by purchasing an additional battery and wiring it in series.
The hardest part of creating an electric skateboard is mounting the motors to the trucks (axles). Other people have achieved this using metal brackets that are welded. I don’t have access to a welder so I used off the shelf components, and 3D printed a motor mount to safely and easily mount the motor. I also 3D printed the gears that deliver power from the motor to the wheels. Initially, reliability may be a concern with 3D printed parts, yet, they are very strong and can be easily re-printed and hot swapped at a very low cost. I have not had to reprint any parts as they have not worn in any way. They are truly spectacular in terms of strength.
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.
