Mini Oscar Mayer Wienermobile Takes Moxie In KC

August 24, 2017 by John Baichtal 4 Comments

There are no shortage of fantastic and creative Power Racing Series cars, but here’s an especially fun example. [Pete Prodoehl] of Milwaukee Makerspace and his teammates [Kathy Cannistra] and [Kyle White] built a Power Racing car based on the design of the iconic Oscar Mayer Wienermobile.

They created the wienie and bun out of fiberglass and foam. Meanwhile, with the KC Maker Faire approaching, the team scrambled to finish the project, with [Kyle] working on assembly while [Pete] tackled the electronics. [Kyle] also proved to be the best wiener rider, with everyone else getting thrown off.

It should be noted that Milwaukee Makerspace got a Moxie bump because a wienermobile is on the PPPRS’s “hit list” of desirable designs. Anyone being the first to create a Top Gun F14, a Mystery Machine, or a non-DeLorean car from Back to the Future gets extra points.

If you like the Power Racing Series, you’ll be able to catch the wienermobile at both Maker Faire Detroit and Maker Faire Milwaukee. Also check out our posts on better racing with Power Wheels and checking a PPPRS car into baggage.

Better Racing With Power Wheels

September 6, 2015 by Brian Benchoff 6 Comments

For the last few months, teams across the US have taken old Power Wheels and other electric vehicles meant for children and turned them into racing machines capable of flying around the track at speeds pf over 30 miles per hour. How do you take the plastic chassis of a kid’s toy and turn it into a Power Racer? [Dane] from team Chibi-Atomic-Thing tells us how.

In classic Power Racing Series fashion, this year’s build began with last year’s chassis. At the 2014 NYC Maker Faire, a weld on the steering linkages failed, necessitating some quick work to replace some bad welds. Poor fabrication wasn’t the only shortcoming of last year’s car; the rear axle was fixed, the brakes were terrible, and the gearbox wasn’t quite as good as it could be.

The team had a few months to make the necessary changes for this season’s races. Because they were adding advanced and arcane technology known as a differential this year, a second disc brake holster would need to be fabricated for the other rear wheel. A new motor controller was added, but the team is mum on why exactly they need an eight-speed gearbox when the longest straight on the track is about fifty feet.

The answer to why a tiny electric car needs more gears than a clock is for now, at least, unknown. Hopefully it will be revealed at the next Power Racing Series race at the NYC Maker Faire in a few weeks. Until then, check out the video of the 2015 Detroit race below.

[Harrison Krix’s] Marriott Chariot

October 25, 2014 by Marsh 6 Comments

Atlanta’s Mini Maker Faire had plenty of booths to keep visitors busy, but the largest spectacle by far was the racetrack smack-dab in the middle, and you’d be hard pressed to find a more eye-catching contender than [Harrison Krix’s] vehicle: the Marriott Chariot.

If [Krix’s] name looks familiar, that’s because he’s the master artisan behind Volpin Props, and is responsible for such favorites as the Futurama Holophonor replica and the Daft Punk helmet. (Actually, he made the other one, too).

The Chariot is yet another competitor in the Power Racing Series, an event that keeps popping up here on Hackaday. [Krix] drew inspiration from this Jeep build we featured earlier in the summer, and went to work sourcing an old plastic body to get started. The frame is 16 gauge square tubing, with a custom motor mount machined from 3/16 steel. After welding the chassis together, [Krix] chopped up a small bicycle to snag its head tube and headset bearings. A pair of sealed lead acid batteries fit horizontally in the frame, providing a slightly lower center of gravity.

[Krix] has a keen eye for precision and his build journal shows each step of his meticulous process. But, you ask, why “Marriott Chariot?” and why does the car look like someone threw up a kaleidoscope? Read on beyond the break, dear reader, to learn the Chariot’s origin and to see a video of it winding around the track.

Jeep Power Wheels Upgrade Only Reuses Body

Power Wheels Racing Jeep

It is debatable whether [Jamie] upgraded his Power Wheels Jeep or built a beast of a mini vehicle and only added a Power Wheels Jeep body. Either way, this Racing Power Wheels Jeep is awesome. The goal of the project is to race in the Power Racing Series races held at Maker Faires.

This vehicle is no joke. It is still electric but runs on 24volts DC. It has pneumatic rubber tires for traction and disk brakes for stopping. The ‘gas’ gauge is a volt meter mounted into the dash next to the motor temperature gauge. As if that was not enough, the headlights and tail lights work. Take note of that sweet custom frame, it was mostly made from an old bed frame.

How This Power Racing Series Car Got On A Plane To WMF

You really should check out the monthly meetings at your local hackerspace. It’s an excellent opportunity to hear the most interesting stories. Like the tale of how the guys from Sector67 got this electric vehicle on the plane with them. Not only did it go up in the air, but they did zero planning ahead of time on how they would actually pull it off.

[Bob Baddeley] posted an album of the PRC experience at World Maker Faire. There are captions that somewhat tell the tale, but we’ll fill you in as best we can on the rest of the story behind this second car from the hackerspace — lovingly known as the Lamebourghini.
