PPPRS, We’re coming for you!


We’re just a few weeks out from Maker Faire Kansas City and the first official race of the season for the Power Racing Series.

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.

We complete against other hackerspaces, like our friends at Pumping Station: One, Sector67, and i3Detroit.

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. ;)

Red Lotus Repairs (Part II)

Power Wheels Repair

We made some good progress last time, but the repairs continue, and this time we got as far as a test drive!

We managed to finish the motor mount, get the chain on, repair the kill switch, and fix a wobbly wheel. We still need to get the new brakes in place, reattach the cooling fan, and see about some replacement wheels. But yes, it is running!

If all goes well we should have it ready by Minne-Faire on April 13th, 2013 in Minneapolis, Minnesota. (We decided not to drive it there, but instead will put it in the back of a regular old gasoline-powered vehicle, just so the batteries are fresh when we get there. :)


Check the video (which is a time lapse of the repairs) and you’ll see a few shots of driving it (note to self: take camera out of time lapse mode when driving!) There’s also a short bit of real-time video at the end showing a first-time guest driver taking it for a spin. (Literally!)

Red Lotus Repairs

Red Lotus Repairs

Tom and I spent some time this past weekend repairing Red Lotus, our #55 Power Wheels Car. Working with Tom is great because I end up learning a ton of new skills, like how to use an angle grinder, and the mill, and some welding tricks. These will all come in handy when the car breaks (and it will break) in the middle of a race.

Besides fixing up the car, we’ve also been building up the team, and it looks like at least two of us will try to make it to Minne-Faire in April for a bit of pre-season racing fun.

Here’s a quick time lapse video of Tom and I doing some repairs.

Boing Boing’d Power Wheels

Remember a month ago when we were racing Red Lotus and Big Jakenstein at Maker Faire Detroit? Well, if you don’t, here’s a nice video for you, which just hit Boing Boing today, which reminded me we never posted this video… So enjoy!

And hey, who else is looking forward to the 2013 Power Racing Series Season? I’ve seen more than a few stock Power Wheels cars around the space lately… just waiting to be transformed into tiny little race cars.

Red Lotus Build [Time Lapse Video]

This is a time lapse video of “Red Lotus” the Power Wheels race car that Milwaukee Makerspace built for the 2012 Power Racing Series. Tom Gr. did almost all the work (with some help!) His original plan was to do the whole build in one weekend… It took a little longer, but not much.

We’re looking forward to the 2013 season and have already started planning. I’m going to say this right now: Sector67 and i3Detroit, we’re coming for you!
