[Jerome’s] been working on some improvements to an electric foot scooter he picked up from a friend. He ordered up a powerful brushless motor and some lithium batteries. His system uses a belt drive and at 33 volts it can reach 25 miles per hour.
He had some problems with too much torque when the motor was first started. This resulted in unintentional wheelies, which sounds really cool if you’re not the one trying to hang on to the scooter. [Jerome] is using an Arduino to control the system so he built in the ability to gradually ramp up the speed of the motor and also added the ability to control the speed via remote control. You should note in the video after the break that [Jerome] is test-piloting his build sans-helmet.
So, we spend a lifetime and countless sums of money filling our noggins with knowledge. This is a precarious investment since a rather small bump to the melon could corrupt all of that data and end the once spectacular cognitive power. If you’re smart enough to build a foot scooter that can go 25mph, be smart enough to wear a helmet when you ride on it!
