Electric Car Power Brakes

May 19, 2014

I was recently asked how brakes work on my electric Geo Metro. I also noticed that every once in a while lately, my vacuum pump wasn’t powering up, so I thought it was about time to take apart the electric power brakes system and examine it. While I did, I took a few photos to […]

E15 Motor Rebuild

July 7, 2013

After looking over the Elec-Trak E15, I saw that one of the blade motors didn’t spin very freely. I went about removing the motor from the deck to see about opening it up, finding out the problem, and rebuilding as needed. Unfortunately, I got stuck on NOT being able to remove the hub that the […]

The ENERGIZER – DIY Exercise Bike Generator

April 14, 2013

I’ve always been impressed with exercise bike generator displays at renewable energy exhibits. So, a while back, when I saw a classic Schwinn exercise bike at the thrift store, I nabbed it with the plan to make it into an EXERCISE BIKE GENERATOR! Earth Week is only a week away, and since our local eco-group […]

PWM DC Motor Controller / LED Dimmer

April 21, 2011

Last week, I started work on a very basic DC Motor Controller.  It’s a really simple circuit that just turns voltage on and off, but very quickly (like about 1000 times a second..) By varying the time off vs time on of the circuit, a Light Emitting Diode (LED) can be dimmed, or a DC […]

World’s Simplest PWM Motor Controller

April 16, 2011

Well, I did it! Knowing nearly nothing about electronics, I managed to finally build my own PWM (Pulse-Width-Modulation) DC Electric Motor Controller! OK, that makes it sound way too fancy. At the beginning of the semester, I signed up for a non-credit electronics class at the local two-year technical college. I’ve been wanting to take […]

PowerWheels Racing: Gravedigger Motor

April 28, 2010

The Milwaukee Makerspace is at it again! This time, participating in “Power Wheels Racing” – modifying stock kids electric vehicles for more power to compete against other teams in tug-of-war, races, and maybe even PowerWheels Polo. Gravedigger is so big, that if it weren’t stock, it would exceed the rules about vehicle size! We actually had […]
