Introducing The Flux Buggy — A Serious Electric Dune Buggy Conversion

May 25, 2014 by 61 Comments

Believe it or not, the writers here at Hack a Day do their own projects too, we don’t just write about yours! I’ve just started a new project, and I want your advice! A few friends and I are converting a custom-made dune buggy — to electric.

The project will be chronicled over on Hackaday.io, with (hopefully) weekly updates on our progress. If you’ve been perusing Projects, you may have noticed my Electric Car conversion from a few years ago. First year of my engineering degree, my friend and I converted a 1993 Honda Del Sol to electric, using the guts of an electric forklift.

We got it going over 100km/h on used batteries our school donated to us. Unfortunately, there was a bit too much red tape and bureaucracy for us to get it on the road legally. That and we were poor university students who couldn’t afford new batteries, or the ridiculous amount insurance companies wanted to put it on the road. The project got scrapped after sitting in the backyard for a few years.

Fast forward to today, and we’ve both graduated and are working our “cushy” engineering jobs, and for the first time in our lives, we have some disposable income. We needed a new project to work on.

Mini Go Kart Built In A Day

The crew at the MIT student-run shop MITERS love their go karts, and when sitting around a pile of parts in the middle of the night on Saturday, there was only one thing to do: build a mini electric go kart in a day.

The parts for this were all taken from the jumble of parts lying around the shop: a few scooter wheels, some aluminum tubing, a 1×4″ piece of extrusion, a huge motor, and a ton of A123 cells were enough to ge tthe project started. They began by bolting the back wheel and motor to the aluminum extrusion and machining a simple steering mechanism.

The real fun began when they realized they could fill the aluminum extrusion with batteries, creating a 6S5P pack with the balance connectors and – after a few tries – the proper insulation. Combine all the parts with a Kelly motor controller and an old Brooks saddle, and the MITERS have a fairly light mini go kart that can cruise around the halls at about 15mph. Not much, but it was built in a single sleep-deprived night.

Video of the kart in action below.

[Charles’s] Epic “Total-Recap” GoKart Post

October 27, 2013 by 11 Comments

If you’ve built an electric vehicle in the past few years, you probably owe [Charles] a couple of beers. Now you can feel more indebted to him after you read his 17,500-word, 10-part post covering everything you need to know about electric go-kart design. You’ll want to grab a sandwich to keep you company.

You probably recall the Chibikart from posts earlier this summer, which is one of an endless list of EV projects [Charles] has up his sleeve. He’s been teaching MIT students how to build EV karts for a while now, and this total-recap “2.00gokart” novel is [Charles’s] way of sharing the wealth. This is more than a simple how-to guide, though. Instead, it reads like a teacher’s edition of GoKarting 101, with a few brief and important histories, walk-throughs of how the class evolved, exhaustive links to vendors, graphs, videos, and plenty of reference and documentation.

If you have even the slightest interest in electric vehicles, do yourself a favor and give it a browse. There are a couple of videos after the break, and if you need some more motivation, check out the EV skateboard that uses a lot of the same parts.

Real Life Mario Karts React To Launchable Items

The team over at Waterloo Labs reasserts their reputation for creativity with this real life Mario Kart project. One of the team members must work at Austin’s Park because they seem to have had free rein when it comes to modifying the go-karts and filming the delightful video presentation found after the break.

It’s one thing to put on some costumes and head off to the go-kart track. It’s another to modify the vehicles to react to items launched by another rider. You can see the painted PVC launcher hardware to the right of each driver. By stuffing a plush item (banana, star, mushroom, etc.) in the barrel the driver can use compressed air to launch it quite a distance. Inside of each item is an RFID tag. When the RFID reader on a kart detects the tag it can take control of the steering, brake pedal, or speed limiter to inflict the appropriate actions.

If you don’t have this kind of insider access to your local go-kart track don’t fret. You just need to build your own set of karts.

Drop Everything And Build This Go-kart Right Now!

May 1, 2012 by 28 Comments

There are awesome projects, and then there are things that make us drool on the keyboard. We just got done wiping up our mess after seeing this go-kart which uses four hub-motors as direct drive wheels. We’ll admit, this is more artwork than a hack as these guys are mechanical engineers and know what they’re doing. But how could we pass up sharing something like this?

The design is smaller than any of the other go-karts we remember seeing. The low-backed pilot seat is the biggest part, with a cubby-hole beneath it for the batteries and control hardware. Each of the hub-motors was hand wound and reading through the related blog posts it seems this was a huge and painful part of the build.

So it’s pretty fun to watch these guys tear up the hallways of one of the engineering buildings at MIT. But the footage of a two-kart race up a spiraling parking garage in the middle of the night is absolutely delightful. You’ll find both videos embedded after the break.
