ElecTrak gets new rims!

April 28, 2010

More work done on the tractor! Turns out I am NOT using those hub adapters. They would have still needed modification to use anyways. The one set of rims was the right size, except that it was for a 3/4 drive shaft instead of a 1″. My friend Rich has a BIG lathe, that he […]

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 […]

Electro-Metro Tablet update

April 18, 2010

Lately, I have been playing with a tablet PC provided to my by my friend Tom. A while back, I mentioned to him how a small computer display would be really handy. So, of course, he dug up an entire computer built around a 800×600 pixel touch-screen display. So far, the main plan was to […]

100,000 miles on electric!

April 16, 2010

The other day, I was pretty excited to have rolled over 2000 miles on my electric Geo Metro since conversion. Well, that would be nothing for Doug Korthof and Lisa Rosen, who recently passed 100,000 miles on their RAV-4 Electric. The following is thanks to Plug In America. “Doug and Lisa’s trusty 2003 RAV reached […]

2000 miles on Electric!

April 11, 2010

Today, I was doing a little more work tinkering with my car, and I realized I just crossed 2000 miles on the vehicle since electric conversion. While that’s still only two-thirds of a traditional gasoline oil change, it’s not a bad distance for not using a drop of gasoline. Another way of looking at it […]

Bob Rice on TV again

April 8, 2010

Last spring, I got to meet Bob Rice at the International Gathering of Citicars in Columbia, Maryland. He is quite a charmer and even had his converted EV Jetta bat cleanup on the drive to Bob Beaumont’s house. Ever since, I have been following his comments on the EVDL (Electric Vehicle Discussion List) where he […]

Electric Car High School Class?

April 7, 2010

For some time, I have been thinking that it would be great to have a high-school class in electric car construction. When I was in high school, algebra and other requirements were not my favorite thing. It seemed like most of my classes weren’t things that would be useful in life. Certainly they were not […]

Fixing up a classic NO GAS lawn mower

April 1, 2010

Last summer, I got the chance to purchase a GE Elec-Trak – a 1970’s vintage battery-electric riding lawn mower. We have had some nice spring weather the last few days, so I took the opportunity to do a little work fixing up the mower. I am repainting it as I can, scraping and grinding the […]

Open ReVolt motor load testing, the cheap and easy way.

April 1, 2010

My friend Chris is building an all-electric motorcycle, but  the best part is that he’s doing it with a very nice Open Source Controller. Built from a kit slightly modified from  Paul and Sabrina’s EV Stuff, the controller will handle 144V at up to 700 amps! Also, Chris’ cycle is off getting a body designed […]
