Harbor Freight

We went crazy a few days before Maker Faire Kansas City and rebuilt a vehicle for The Power Racing Series. The boat that was a basket turned into a duck…

Of course no PPPRS trip is complete without a stop at Harbor Fright. We bought all the pink tires they had. You know the pink tires, the ones the destroy themselves? Yeah, those pink tires…

Duck Car

Duallies again! Brings back memories of Red Lotus, doesn’t it? But this time we did not destroy any pink tires. We destroyed other things, but we fixed most of them.

Duck Car

Ed was our primary mechanic and handled all of the electrical system stuff and most of the other difficult things. Ed has a lot of experience building cars and other things…

Duck Car

Lori (aka “The Lorry”, aka “The Truck”) has raced before in Kansas City, and it was good to have her back behind the wheel, er, well, handle bars… Unless you count the main drive wheel when we say wheel. Yeah, let’s talk about that bicycle hub motor that runs at 24 volts, and not 36 volts.

Duck Car

Kathy went full-on duck, but can you blame her? About that hub motor… It’s built for 24 volts, but after the controller malfunctioned we switched it out for a 36 volt controller, which would only work with 36 volts attached to it, so we added a third battery and went crazy. Things worked until they didn’t and the motor burned up, even though we kept pouring water all over it. Drat!

Duck Car

Well, that’s the way it goes in the PPPRS, you either taste victory or you smell things burning. We did manage to get within the top five during the Endurance Race, and maybe even hit second place at one point. It’s all a blur really, and honestly we care more about having fun than we do about winning.

See you in Detroit!

Nerdy Derby Wheels Keep Rolling!


We’ve been printing wheels… lots of wheel! We tested some at Madison Mini Maker Faire’s Nerdy Derby event last weekend, and we’ve been using Son of Megamax to crank out little plastic wheels.


Yes, we are printing 37 wheels at a time! And we’re using ABS filament from CoEx in Appleton, Wisconsin. They were kind enough to supply us with some spools of filament to keep SoM busying printing pretty much day and night!


I know you’re wondering how we keep an eye on all those wheels being printed. Well, when we’re not at the space we just check out the Milwaukee Makerspace Webcam. (As long as it’s pointed in the right direction.)

Drive Time!

Hard Drive

A few of us have been working on a project each Tuesday night which involves dismantling old hard drives.

What do you get from an old hard drive? We’re saving the cases for an Aluminum pour at Maker Faire Milwaukee, the motors are super-fast and super-quiet, there are some tiny bearings we might use, and there are powerful magnets, some of which we’ve used to hold tools to the wall in the past, and finally, those shiny, shiny platters!

Hard Drive Platters

We’ve got a stack of about 80 platters, with more coming. If you’re wondering what we’re going to do with all the platters, well… yeah, some sort of project for Maker Faire. That’s all I can reveal right now. :)
