Several months ago, a humorous request went out for a Zamboni that could be used on the Nerdy Derby track.
Last year the Milwaukee Makerspace held a Maker Fest and a Nerdy Derby track was made for the occasion. The design allowed the track to be disassembled in 4 foot long sections.
When the track was reassembled, earlier this year, for the South Side Chicago Maker Faire, it was found that the joints did not match up as well as when it was first put together. Small ledges, that went up and down, would cause the cars to bounce off the track or hit the bottom of the car. Both of these scenarios prevented the cars from traveling freely down the track.
As many of you know, we just had a GREAT Maker Faire here in Milwaukee last month and the Nerdy Derby track was needed again!
We produced, and ran, over 1000 Nerdy Derby cars over the 2 day event. Wow!
A month or so before the event I started working on an idea for a Zamboni type of device. My first thought was of a custom contoured planer that could be used at each joint to smooth them out. This idea seemed like too much work so I proceeded forward with my second design. This consisted of a simple sled hat used a drum sander, which smoothed out the high spots. Wood putty was then used to fill in any low spots.
If you’ve seen Mr. Fusion around the space, or at one of the Power Racing Series events this year, you’ve probably wondered what it looked like before we, uh, had our way with it.
It took a bit of digging, but I found an old photo of Mr. Fusion (aka Cinderella) it its original state. Baby blue, pink, and basically a pretty, pretty princess.
Matt W. started the build on this thing, and Chris H took over from there. I ended up doing the body work because I didn’t care for the plain look of it. (We had already removed the Cinderella decal.)
The car was named “Mr. Fusion” due to the vertical motor mount in the back, as a reference to the “Back to the Future” films.
Anyway, this was my attempt to make it look just a little bit more like a DeLorean than a Pontiac. I’ll have a follow-up post detailing more on the body work, and hopefully someone who knows about what’s going on under the hood (and trunk!) can post about that.
And for those of you that don’t know, the Power Racing Series (typically abbreviated to “PPPRS”) is a challenge to create a working electric vehicle for less than $500 using open source tools and tech. But we use Power Wheels Cars… yeah, the ones designed for little kids. We rebuild them to hold a full-size adult driver (some of us are even, uh “extra large” as it were) and the add in beefy motors, rechargeable batteries, motor controllers, brakes, sometimes trailer hitches and parachutes, and race ’em.
This season we hope to have three cars functional for the races. You may have seen some work on Red Lotus recently. While it was one of our main cars last year, it’s probably the slowest car we have right now, of course speed isn’t everything in the Power Racing Series, and who knows, we may have a few tricks up our collective sleeves by the time the race at Maker Faire Detroit rolls around. ;)
Did you know that we’ve got a number of members who have built electric cars? Ben Nelson even runs 300mph.org and has published DVDs and Instructables showing you how to build your own. (Sharing of knowledge is a top priority for our members!)
If you’re interested in electric cars, come on down to Milwaukee Makerspace at 1pm on Sunday, February 10th, 2013 for the first Milwaukee Electric Car Club Meeting at our new location. Got a Tesla, or a Volt, or some DIY/converted vehicle? Bring it! Just want to learn what these electric vehicles are all about? That’s cool too!
