[Petter] built himself a DIY Segway out of a couple of cheap electric scooters. We’ve seen a couple of very nice Segway builds in the past like the all analog Segway, or the creepy walking version, [Petter]’s Segway build seems like it would be a useful human transport device.
The motors, chains, gears, and wheels are scavenged from a pair of electric scooters. Steering left and right is accomplished by tilting the handlebars left and right. The handlebars themselves are attached to the joint at a base that allows them to be taken on and off. We’re thinking this would be great for throwing a [Petter]’s Segway in the trunk of a car – a design feature the original Segway doesn’t have.
The electronics of the project are based around an ATMega168 that reads data from an accelerometer and gyroscope. The motors are controlled by two H-bridges and are powered by two 12 V lead batteries wired in series. We’re not sure how long the batteries will last in a real-world situation, but [Petter]’s build seems to go fast enough.
