Red Lotus

Posted on by Audrey Horst

All the other PPPRS cars got an upgrade post, it’d be a shame if Red Lotus didn’t get one too.

Before continuing, I should mention my involvement in this little beastie. I kind of got sucked into the Power wheels group at the space straight away: I joined the space in the middle of July, was riding around Baby Burrito for a parade the very next day, and went out to Detroit for my first PPPRS race a week or two later. Naturally, being a tiny little thing myself, I fell in love with this fast little car. (My goodness, I was so green at that Detroit race, there were orange treadmarks all over that course.) Red Lotus tends to eat through tires, but when we tried a new double-tire strategy, we had to cut the body to pieces in order to make more clearance for the wheels (and to use JakeNStein’s/Mr. Fusion’s batteries, but that’s a whole different story.) When we returned from Motor City, there was quite a lot of bodywork to do…

I started off by reconnecting the hood and the doors to the rear with a few screws and strips of aluminum siding. Then paint happened, because why not. After removing the old stencil work with Goof-Off (I had originally tried to paint over the old numbers, but they bled right through my paint), I sprayed on a thin coat of red with a heavy focus on clearing scuffs.

Once that was dry, I had a field day with some old Testor’s enamel. The door numbers didn’t turn out quite as well as I was hoping for, but painting out the license plate and Makerspace logo made my day instead. Note: silver enamel bleeds through everything you throw at it. It’s best to not fuss about it and just let it do what it wants.

Then I made a nice thing on the hood with acrylic. I was originally going to try using enamel, but that’s a level I have yet to obtain. The work kept scratching off, so I put a good 3-4 extra coats of sealant on it.

Along with a fantastic new disc hub which was hand-machined by Tom, Tom, Tony, and a few other great guys (oh, and a mountain of 99 cent tires that hold up much better than anyone could have expected), the whole upgrade ended up quite fierce, I believe. 

The space went out to compete in the Fort Wayne Makerfaire soon after and we had a marvelous time. Got a bit scraped up, but I ain’t even mad. I think it gives the car more character that way. IMG_20130915_153648

After Indiana, we shipped out Red and JakeNStein out to New York for FINALS. However, there were a few fixes we needed to perform beforehand. We took home Red’s bent up left steering knuckle to straighten out and reinforce. Thanks to Dan, Joe, Tony, and Matt for helping me get that done in such a small time frame!

Once we were all fixed up and ready to race, Red Lotus did much better than anticipated. Along with Jake’s 3 silvers in the 25 lap heats and Endurance race, Red Lotus got a silver, a 4th, and a 6th in the 25 lap races, and  another 4th in the enduro. Red even won the Exhibition/for funzies race! All in all, I think we had a marvelous season, and I’m really happy and grateful for all the friends I’ve made and all the wonderful help I’ve received and all the cool stuff I learned. And of course, for the spectacular Milwaukee Makerspace for being the coolest pack of people ever.

Even though I’m sad the season is over, there’s still plenty to do in the off season. One thing is getting a more hefty pair of steering rods in place and putting in some stronger reinforcement for the steering knuckles. The amount of times I’ve had to pit this season from not being able to turn in a particular direction is just too darn high. Another top priority is getting a second motor onto the left rear wheel so the power is a bit more evenly distributed. However, that may make me too light to drive it without continuously drifting, but I don’t think that’s necessarily a bad thing…

Mr. Cinderella Fusion

A Pretty Princess

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.

Power Racing Series – Detroit 2013

Posted on by Pete Prodoehl

Milwaukee Makerspace Racing Team

The Milwaukee Makerspace Racing Team (Pete, Chris, Tony, Sean, and Audrey) took three cars out to Maker Faire Detroit to race against other hackerspaces around the country. How did we do? We did pretty good! And by “pretty good” I mean that we had fun, no one got hurt (too badly) and we returned with plenty of good stories to tell.

Chris on Mr. Fusion

Since Matt W. couldn’t make it, Chris took over Mr. Fusion (our newest car) for the weekend. There were some transmission problems, which we got figured out, but Mr. Fusion failed before the end of the weekend, which we sort of expected. The highlight of the weekend was Chris flipping the car and getting pinned under it. (Well, he might not agree it was the highlight!)

Tony on Jake N Stein

Jake N Stein was driven by Tony and myself, and I think Chris may have take a few laps as well. Jake N Stein did pretty well during the weekend, and only died right before the end of Sunday’s Endurance Race. Jake N Stein is pretty solid right now, though we’ll probably be upgrading the water cooling system for the motor. We did get a warning for “being on fire” that was actually just steam. Luckily it wasn’t 95 degrees in Detroit this year.

Dan on Jake N Stein

Dan (our resident Blacksmith) gave us a call as he just happened to be in Detroit for the weekend, so we recruited him and he ended up driving Jake N Stein during some of the races!

Audrey Fits

This photo shows that Red Lotus was pretty much built for Audrey, and by that I mean, she’s the only one who can sit in it and not have her knees sticking way the hell out.

Audrey on Red Lotus

Even when we forget the right batteries and have to do an emergency battery replacement, it’s no big deal to Audrey. It helps to have a driver that you can fold in half to fit into the car. Oh, the batteries, yeah… we somehow left the small batteries Red Lotus uses in Milwaukee, so we rigged up the big batteries the other cars used, and removed the hood of the car, and attached it to the trunk. I figured we couldn’t leave it off because (1) it’s part of the original body, and you’re supposed to maintain that and (2) the transponder was attached to it. So we zip tied the hood onto the trunk, which worked fine, until…

Sean on Red Lotus

Sean was driving and the hood (and transponder!) fell off. We tried to get Sean into the pits but he just grabbed the hood and did a bunch of laps holding it. It totally worked and gained us a few laps until we had to pit.

The Pits

All in all, the Power Racing Series event in Detroit was awesome. We met a lot of cool people, and worked together as a team to get all the cars functional and keep them functioning for the races.

We’re currently planning to head to the Fort Wayne Regional Maker Faire in September for one more race. We may even try to build a new car by then, because we are crazy.

PPPRS, We’re coming for you!

PPPRS

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)

Posted on by Pete Prodoehl

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. :)

Driving!

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!)
