Man, Stranded In The Desert, Makes A Motorcycle From His Broken Car

May 21, 2012 by Caleb Kraft 190 Comments

The original story is in French, and the Google translate is very rough. Please forgive us if we don’t get this completely accurate.

While traveling through the desert somewhere in north west Africa in his Citroen 2CV , [Emile] is stopped, and told not to go any further due to some military conflicts in the area. Not wanting to actually listen to this advice, he decides to loop around, through the desert, to circumvent this roadblock.

After a while of treading off the beaten path, [Emile] manages to snap a swing arm on his vehicle, leaving him stranded. He decided that the best course of action was to disassemble his vehicle and construct a motorcycle from the parts. This feat would be impressive on its own, but remember, he’s still in the desert and un-prepared. If we’re reading this correctly, he managed to drill holes by bending metal and sawing at it, then un-bending it to be flat again.

It takes him twelve days to construct this thing. There are more pictures on the site, you simply have to go look at it. Feel free to translate the labels and post them in the comments.

Update: From [Semicolo] in the comments

You got the translation right, but there’s not just a swing arm that’s broken, there’s a frame beam broken too (not sure about the exact term, one of the 2 girder of the chassis).
He’s not far away but he has a lot of tools and other hardware that could be stolen if he leaves them unattended.

DeLorean Hovercraft

May 20, 2012 by Caleb Kraft 11 Comments

[Matthew Riese] got frustrated waiting for the future to arrive so he could have his flying car. He decided to take things into his own hands and construct the closest thing he could. This turned out to be a hovercraft. Not only that, but he thought that the most fitting shape for this thing would be a DeLorean. We can’t say that we disagree with him. Unfortunately, there isn’t a whole lot of information on his build. There is this cool video on his kickstarter page (don’t worry, he got funded back in 2010). To make up for the fact that the build information is sparse, we’ve found you some plans to make your own hovercraft. Just add whatever shape body you want, though we have some suggestions.

Amphi-Cycle Lets You Ride The Trails, The Waves, And Back Again

amphi-cycle

Hackaday regular [Berto] is always looking for new ways to get around, and wrote in to share his most recent creation, an amphibious bicycle.

He bought an off-the-shelf inflatable boat and constructed a rig that allows him to stably mount the bike on it. Once [Berto] comes across a body of water he wants to cross, all he requires is about 7 minutes time to inflate the boat and attach his bike. Using a modified version of his electric drill-based trolling motor we saw last year, the Amphi-cycle glides across the water effortlessly as demonstrated by his assistant in the video below.

Right now the boat is propelled solely by the trolling motor and a large lead-acid battery. We would love to see the amphi-cycle powered by its rider, though we don’t know how that would affect the “one boat fits all” design [Berto] is aiming for.

The WiiKart, A Wireless Go Kart

May 11, 2012 by Caleb Kraft 15 Comments

Whoops… Looks like we covered this already. My mistake.

In case the name didn’t tip you off, this fun little kart was inspired by MarioKart. The goal was to build a functional go kart that could be controlled via the Nintendo Wiimote. They did a pretty good job and kept it fairly simple too. They designed a frame that vaguely mimics the shape of the carts in the game. The steering is handled by a 4″ stroke linear actuator. This was initially hooked directly to the tie-rod, but they found it to be too slow. Their solution was to put a lever in between the two with a 1to 3 ratio. This made everything much snappier.

Though they were capable of implementing PWM on the motors in their hardware, they opted to stick with full on, full off because of the push-button nature of the controller. The connection and communication are handled with an Arduino and they don’t mention what bluetooth module they use.

You can see in the video below it is fairly responsive and has more than enough power to lug a passenger over some varied terrain.

Drop Everything And Build This Go-kart Right Now!

May 1, 2012 by Mike Szczys 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.

Rail Bike Conversion Is A Success, And A Failure

May 1, 2012 by Caleb Kraft 40 Comments

There is a long tradition of hacking transportation to work on the rails. People have done it to all kinds of things for many reasons. Some are for rail maintenance, others are simply to enjoy the tracks. With as much unused railways as we have, it seems a shame to waste them. This hack turns a bicycle into into a rail bike with the use of some conduit, a cut up razor scooter, and a fork from another bike. After some tinkering with spacing to make the whole thing a little smoother on the rails, the whole thing seemed like a success. That is, until the front rail guide caught a railway tie and the rider was tossed. Not only that, the impact destroyed his bike frame.

So, does this wreck mark this as a failure? Or is this simply another step in the iterative process we all tend to use. The only difference is if he carries on to build another.

Home Brew Motorized Bicycle Is A Super Grocery Getter

April 28, 2012 by Brian Benchoff 14 Comments

[Thor] sent in an awesome motorized bike build he found coming from the fruitful workshop of [Jim Gallant]. It’s an incredible piece of work built nearly entirely from scratch.

[Jim] welded the frame together on a home-built jig that keeps all the chrome-moly tubes in alignment before they’re pieced together. With the jig, the frame was kept extremely straight making a bike that turns very well and can be ridden no-handed.

All of [Jim]’s previous motorized bikes used small Honda engines, but after hearing Robin Subaru engines are more reliable he decided to give one a go. The motor is attached to the derailleur gears with a continuously variable transmission usually found in scooters. [Jim]’s earlier motorized bikes didn’t have indexed shifting and disc brakes like modern motorized bikes, but he decided to throw them in anyway. Everyone who rides his new super grocery getter comments on how smooth the ride is with these additions.

While [Jim] doesn’t have an official speed or MPG rating, he’s guessing this bike can carry three bags of groceries at 30 mph at 170 miles per gallon. A very efficient mode of transportation that is much safer than the other motorized bikes we’ve seen before.
