X-Men: Days of Future Past is making its way to theaters around the world, and [Mr. Furze] has released his second X-Men related hack — Magneto Boots.

In case you missed it, [Colin Furze] has made three projects to celebrate geekdom and a mastery of fabrication for all the comic book fans out there. He started with the fully functional pneumatic Wolverine Claws, and now he’s tackling Magneto’s powers. The third project isn’t out quite yet, but we can’t wait to see the final installment!

Now the problem with Magneto is his powers are a wee bit too… magical? Without special effects, you can’t really replicate his mutant abilities (please prove us wrong if you can!), so [Colin] decided to do the next best thing. Magnetize himself — well, his shoes.

Home Depot Brand Boat Costs $29.18

It is a common belief (or fact, depending who you talk to) that boats are money pits. Surely, it is a fun past time even for the lucky person flipping the bill, but what if you could build a boat from locally found and purchased items. [Bill] did just this and he did it for a mere $30. His creation is affectionately called Thunder Bucket.

The overall design is a pontoon-based sail boat. You’ll notice from the photo that the pontoons are made from many 5 gallon buckets attached together. The wood frame and deck come courtesy of old pallets that were taken apart. The mast is a fence post and a standard blue tarp rounds out the resourcefulness as it is used for the sail.

Admittedly, this may not be the coolest boat on the waterways but it is a boat, it’s made from non-boat-like items and it works. Believe it or not [Bill] is a professional boat builder. Sometimes ‘why not?’ is the best reason to do something.

Electric Go-Kart Made From Off The Shelf Components

Eletctric go kart
What would you do with a catalog of parts and a nice budget? [Ben Rothschild] decided to build an electric go-kart from scratch, for a contest he’s trying to win.

He designed the entire go-kart in 3D CAD using off the shelf components to speed up assembly. The frame is made of aluminum extrusion with t-bolt brackets, and he’s using modified FIRST Robotics wheels with standard #25 chain and sprockets.

Two 1850W Turnigy SK3 brushless motors make up the drive system, equivalent to almost a 5HP engine — except with a constant torque profile, meaning it’ll have no problem going up hills at 3km/h or 30km/h, no gearing necessary! To power the beast he’s using four hard-shell LiPo batteries (4S1P), which are rated for 14.8V and 5Ah. Two el cheap-o 24V 500W speed controllers (slightly concerning) provide the control system, which he may plan to upgrade in the near future.

The test drive video is a bit short, but it looks like with a bit more work this go-kart could have a lot of potential!

Home Made Cargo Bicycle Makes Use Of Scraps!

Recycled DIY Bicycle!

Ever heard of a cargo bike? If you need to carry a lot of stuff around (or maybe even your kid!), then they’re super handy — unfortunately, they aren’t exactly cheap — or common. So you could just make your own…

[Matthew Venn] was inspired by Tom’s cargo bikes, recently featured in issue 12 of Boneshaker magazine. He collected a few scrap bicycles, some steel, and started fabrication — lucky for him, his friend [Eric] has a full metal working shop complete with plasma cutting, MIG welding, and a lathe.

They started by cutting the front end of the bicycle off and replacing it with a much longer steering column. This connects to the only new part they had to buy — a pair of Ford Escort tie rods, which allow you to steer the tiny front wheel. They continued welding the rest of the frame together, testing it as they went — once satisfied with its handling (it still needs brakes) they built the cargo platform and called it a day.

There’s a complete gallery of the process over on [Matthew’s] Flickr, so if you’re hoping to make your own, take a gander!

Intelligent Roadways Pave Way To The Future

smart roadway with illuminated tiles

The idea of a road is relatively simple – a durable path from point A to point B. Development of roadways usable for wheeled carriages has been perfected over the centuries. The Romans, for instance, used a base layer of crushed limestone that would let water flow out, preventing clay soil from turning into mud. Some Roman roads were topped with six sided capstones, also known as pavers, many of which still exist today.

The invention of the horseless carriage necessitated roadways that could be used at high speeds. Tarmac, asphalt and concrete roads followed, and thus ends our short venture into the history of roads. Roadways simply haven’t changed much since then. Sure, we’ve painted some lines on them, even etched grooves in some to prevent accidents, but the core technology of the road is the same as it was a hundred years ago. Until now. Consider the Intelligent Roadway.

[Scott] is an electrical engineer, and had dreamed of solar powered roadways as a child. But it wasn’t until the realization of global warming did [Scott] and his wife, [Julie] start to take the concept seriously. Stick around after the break to find out just how smart [Scott’s] roadway of the future is.

Koenigsegg 3D-Printing For Production Vehicles

Koenigsegg with Printed Parts

We’re not surprised to see a car manufacturer using 3D-printing technology, but we think this may be the first time we’ve heard of 3D-prints going into production vehicles. You’ve likely heard of Christian von Koenigsegg’s cars if you’re a fan of BBC’s Top Gear, where the hypercar screams its way into the leading lap times.

Now it seems the Swedish car manufacturer has integrated 3D printing and scanning into the design process. Christian himself explains the benefits of both for iterative design: they roughed out a chair, adjusting it as they went until it was about the right shape and was comfortable. They then used a laser scanner to bring it into a CAD file, which significantly accelerated the production process. He’s also got some examples of brake pedals printed from ABS—they normally machine them out of aluminum—to test the fits and the feeling. They make adjustments as necessary to the prints, sometimes carving them up by hand, then break out the laser scanner again to capture any modifications, bring it back to CAD, and reprint the model.

Interestingly, they’ve been printing some bits and pieces for production cars out of ABS for a few years. Considering the low volume they are working with, it makes sense. Videos and more info after the jump.

The P.u.l.s.e Parking Light

May 8, 2014 by Brian Benchoff 36 Comments

[Anool]’s brother loves his motorcycle, and when he came across a ‘breathing LED’ mod for the brake light, he had to have one. Being tasked with the creation of a pretty cool mod, [Anool] came up with p.u.l.s.e., an extremely small LED controller and a slight tip ‘o the hat to Pink Floyd and the second or third greatest CD packagings.

The circuit is a slightly Apple-inspired mod for the parking light that keeps the lamp fully lit when the Neutral Detect line on the bike is high, and slowly pulses the LED in a ‘breathing’ pattern when the Neutral Detect line is low. Not a lot of logic is needed for something this simple, so [Anool] turned to the ATtiny45 and the Arduino IDE to accomplish his goal.

[Anool] created a circuit in KiCAD that would plug in to the lamp socket of his brother’s bike. A cluster of LEDs replace the T10 lamp inside the parking light, and a small amount of code takes care of the logic and breathing effect. It’s a great mod, and the astonishingly small size of the board puts him in the running for the smallest Arduino we’ve ever seen.

Videos of the light in action below.
