Rocket Board: The Propellor-Powered Skateboard

Ryan Bavetta’s Rocket Board doesn’t actually use a rocket, but it does look like one. The home-brew prop-powered skateboard carries a 3.7 HP model airplane engine which powers a propellor in a standard house-fan cage. It doesn’t use gasoline or kerosene but proprietary Glow Fuel, a dangerous sounding mix of methanol, nitromethane and oil. The setup is enough to spin the prop at up to 10,000 RPM which, as you can see, can easily shift a person.

What we love best about this video (apart from its entertaining professionalism and the freakin’ rocket board) is that it shows the whole crazy boffin project, from the first test with a household fan and a car battery (FAIL) to the inevitable golden-hour run with POV-cam. Bavetta even built his own skateboard to mount the fan.

Finally, a word to our British readers over 35 years old. This Rocket Board is the exact same thing as you may have seen in Sammy Brewster’s Ski-Board Squad, a comic strip which ran in Buster back in the 1970s about a gang of crime bustin’ kids riding, you guessed it, motor-powered skateboards. Ryan Bavetta, you’re my hero!

DIY iPhone Dock Made From Dead CDs

recycled-cd-iphone-dock

What do you do once you have ripped every last one of your CDs to MP3 format? Take out a Dremel and some glue and turn them into a stand for your iPhone, of course. Those pointless plastic disks can now sit supporting your MP3 player rather than taking up much needed landfill space.

To make the Recycled CD iPhone Dock you just stick a stack of CDs together and then shave out space for the iPhone USB cable, following the simple instructions (if you need them) over at Geeky Gadgets. We’d echo commenter Keith’s concerns, though – that the iPhone is not actually supported – and stack a few extra CDs on top, then carve out a more cosy space for the iPhone to rest in. A great DIY project which proves that CDs are good for something other than keeping coffee-rings off the desktop.

Chinese Bike Mod Floats on Water

floating-water-bike

For bike enthusiasts, ain’t no mountain high enough and now ain’t no river wide enough. A Chinese man has created an amphibious bike that travels as well on land as it does on water.

A few large empty water bottles and a touch of madness is all it takes to do this mod. The bike uses eight gallon water bottles attached to a metal frame to keep it afloat. Paddles on the wheels allow it to be  maneuvered on water. On road, the water gallons are pulled up and it becomes just another bike zipping along.

The bike made by Li Weiguo was shown in the Hubei province in China. It cost around 20,000 yuan or $300o to develop, says Inhabitat.

While, for now,  it may be a novelty, Li Weiguo is seriously looking for a manufacturer for his invention. Any takers?

Clocks, Tables and Chairs Built From Old Bike Parts

recycleddesign1100

If you have stripped down an old road bike and turned it into a fashionable’n’fun fixed-gear machine, you will have a bunch of parts left over. Once you have weighed them in your hands and laughed maniacally at the sheer weight of the gear cassettes and brake assemblies you no longer have to carry with every single revolution of the pedals, you might wonder if you can recycle them.

If so, you may consider a rather stylish clock, just like those made by Kenneth Armstrong. He has been tinkering with cogs, disk-brakes and even entire wheels for seven years, combining parts into these sculptural timepieces. There’s something of the steampunk about these, and if you check out Armstrong’s site, you’ll see he’s been rather busy, turning out locking posts made form old d-locks and tables fashioned from bike wheels and tubing. There’s even a rather uncomfortable but cool-looking chair welded from old handlebars. We love them.

Juicers Made from Old Water Bottles

Remember Scott Amron? He brought us the water fountain toothbrush and the magnet-powered, clip-free Endo fridge-magnet. Now he’s lopped the bottoms off a stack of spring-water bottles and will sell you one to juice your oranges.

Scott is asking $6.50 for these punts, aka the stiffening dimple in the bottom of a large plastic bottle. This is ripe (sorry) for a DIY version, although it looks like Scott’s brand of choice, Poland Spring, has a particularly handsome punt. I will be making one of these.

AMD Phenom II Processor is Overclocked to 6.93 GHz

amd-overclocking-693

A team of AMD engineers claim they have broken the overclocking world record for quad core x86 processor frequency.

At an event hosted by CompUSA in Miami, the engineers used liquid nitrogen and liquid helium cooling to reach 6.93 GHz on an AMD Phenom II X4 955 Black Edition quad core processor.

The 6.93 GHz speed, claims AMD, beats the previous record of 6.89 GHz for Phenom II quad-core processors. It is also more than twice the 3.2 GHz normal clock speed for the processor. AMD engineers cooled the processors to under three degrees kelvin or below 425 degrees Fahrenheit (-270 degrees Celsius)  to get the results.

Hackintosh Retail Store Could Upset Mac Status Quo

2401-west-main-street-alhambra1

If you’re passing 2401 West Main Street, Alhambra, California anytime today (above), go take a long look, as it will likely be the shortest tenure of any retail store, ever. Why? The latest tenant is called Quo Computer, and today it opens a retail store selling fake Macs.

The founder, Rashantha De Silva, is charmingly optimistic about his suicide mission. Speaking to Cnet News, he said:

It’s exciting. We are trying to stay as close to Apple as we can with our products. We are trying to mimic things as much as we can. I’m hoping that Apple sees the value in what we are doing.

Oh, ho! Da Silva is not quite as naive as he seems, and fully expects to be sued by Apple. Somehow, though, the fact that his company plans to make prettier computers than other hackintosh makers, and will offer customer service “up there with Apple’s” makes Da Silva think that things will be different this time. “[…] we have a different attitude. There are thousands of people in the ‘Hackintosh’ market, but many of them are creating bad products.”

It’s like an article in a trashy women’s magazine: “He beat his last five wives to death, but I can change him.”

So, if you’re in the market for a Mac clone which you will doubtless be coddling with driver updates just to keep it running, head over to the bricks’n’mortar store, which opens today. There will be three models on sale, the Life Q, Pro Q, and Max Q, starting at “under $900″. Da Silva will be the nervous guy constantly glancing over his shoulder.

Nike+ Hacked to Open Cars From Afar

ifob

Some years ago, Top Gear’s Jeremy Clarkson was dealt a healthy dose of paranoia when he tested out a Mercedes with keyless entry. The car would lock and unlock automatically if you had the fob in your pocket. The trouble was, Clarkson never knew if the car was actually locked. If he went back to check it, the door just opened again.

Nathan Seidle of Sparkfun electronics decided he needed the same level of niggling worry in his life and rolled his own car-opener with a Nike+ dongle and receiver, an Arduino board, a Nike+iPod Serial to USB Adapter and some creative sabotage.

With a little plugging, soldering and very simple programming, Nate has himself a widget in the cart which constantly beeps out a signal, fishing for an in-range Nike+. When it hears one reply, it decodes its unique ID and if the “key” fits, the car opens. But Nate, like Clarkson, had a problem:

While testing I found the range of the transmitter (the footpod) was really pretty impressive at 50+ feet. This was cool, but I didn’t want my car to be unlocking/lock while walking around my house or office.

The answer? A Tin-Foil hat. A few wrappings of aluminum foil and the range was halved. The car itself ignores the iFob while the engine is running, so it can’t switch off on the road, and Nate has finally rid himself of his final mechanical key. We just wonder what he’s going to use to scratch up any cars that steal his parking space.

Used Soda Bottles Find a New Lease of Life

sodabottlewave

SAN MATEO, California — Drinking too much Mountain Dew? Then the Soda Bottle Wave might just be the project for you. Reuben Margolin, an Emeryville, California- based artist has strung together a 20-feet tall installation created out of 612 used one-liter soda bottles.

“Think of it as a curtain of undulating plastic bottles,” says Margolin of the project on display at the Maker Faire DIY festival.

Margolin took about six months to make it. That includes about 80 hours spent on cleaning the bottle, steaming out the labels and sterilizing them. He drilled holes into the bottle caps and hooked them up using steel clips with each junction linking to four bottles. The entire installation hangs on a circular handle about 12-inches in diameter.

And no, Margolin didn’t drink all that soda.  He and a friend visited two recycling centers in the area to get all the used bottles they wanted.


Hand of Man Robot Tries to Reach for the Gods

handofman1SAN MATEO, California — To stand out among a beautifully, constructed, near-authentic steam carriage and a fire-breathing installation that spews out a flame every few seconds isn’t easy.

But if one project can grab attention it is the ‘Hand of Man’,  an outsized hydraulic arm that can be operated from a little gloved controller nearby.

“It’s modeled on the human hand and foreman and has the same range of motions,” says New Mexico-based artist Christian Ristow took about six months to build the installation.”It is all hydraulic and powered by diesel engines.”

The initial funding for the project came from the Burning Man festival last year and since then Ristow has honed the machine and added more functions.

The 25-feet tall arm has been created such that anyone from the audience can walk up to a little platform and stick their hand into a glove. The motions inside the gloved controller are reflected in the giant hand.

“There’s a feeling of power that goes with controlling a robot of this scale,” says Ristow. And that arm has the power to inflict some serious damage including the ability to pick up a small car and toss it back to the ground.

Operating the installation itself is pretty simple and intuitive says Ristow. And to prove him right, next in line to try out the Hand of Man was a five-year old boy.

For more on how Ristow’s Hand of Man was created, check out his blog.

Here’s also a video of the Hand of Man from the Burning Man festival.
