Bicycling In The Fall

bicycle

Every year, as it gets cold, many of us put our faithful two wheeled companion away for the winter.  Despite that, there have been a veritable smorgasbord of bicycle related projects posted to instructables this last week. In honor of our human powered transportation, lets take a peak at a few projects.

Bicycle safety is always paramount. They can be fairly difficult to see compared to a car. There are many ways to make them easier to spot, such as wrapping them in reflective material, or adding blinking tail lights. Even if people do see us, they often have no idea where we are planning on going. To remedy this, we can always add turn signals. It can also be hard to see where you are going at times. Adding a head light, or helmet light can really help. If you’re not a big fan of LEDs and want a little retro flair, you can always add an oil lamp.

For those who live in warmer climates, or just can’t give up their bicycles, you may wish to add some festive decorations. Covering your bike in Christmas lights doesn’t look too difficult, and a CFL lit wheel is a cheap way of adding some cool effects.

CCFL Bike Wheel Lights

We’d never discount the beauty that is the SpokePOV bike wheel kits, but if you want to just turn your bicycle into a blinding blur, [depotdevoid] has the solution for you. He had a CCFL tube left over from an abandoned LCD monitor backlight repair, and decided to see what it would look like as a wheel light. The result turned out fairly well. He had to figure out how to mount the 8 batteries plus step-up board. He says the extra weight isn’t really noticeable and the light output is quite bright. CCFLs can be incredibly fragile, so take care when you do the actual mounting.

Spoke-o-dometer Bicycle POV Speed Display

[Rory Hyde] and [Scott Mitchell] are exploring several projects that add more information to public spaces. The first is the Spoke-o-dometer a persistence of vision device that can display bicycle speed and distance traveled. To develop the device, they first bought a few POV kits to test out. They decided to build their version using an Arduino. Once they had the display proof of concept working, they added a hall effect sensor like the SpokePOV so they could determine speed and orient the display. Check out their project site for plenty of example code and development details.

Flying Cars A Reality

[Stillboy] alerted us to a flying car that runs on biofuel. Flying cars have been the mainstays of science fiction and technological wish lists for years, but they elude production, as expenses, fuel, and gravity get in the way. [Gilo Cardozo], a paramotor manufacturer, managed to overcome those hurdles by thinking simply. He attached a paramotor to his car, which is powered by a Yamaha superbike engine and a gearbox from a snowmobile. His modified Rage Motorsport buggy is street legal in the United Kingdom, and in the air, can get up to 80 miles per hour. It will be fully tested in January, when he and his chief pilot and expedition organizer [Neil Laughton] drive and fly the car to Timbuktu.

Other flying cars are also in the works. DARPA recently announced their Personal Air Vehicle Technology project that will hopefully lead to a military-suitable flying car that can get up to 60 miles per hour on the ground and 150 miles per hour in the air. Moller International claims that a flying Ferrari is in the works, and could be available for purchase within two years. Are jet packs next?

Hacking The MINI Cooper

[war6763] sent us this hack to power an amplifier in a MINI Cooper. Apparently, aside from being unconventionally handsome, they’re also unconventionally wired. Amplifiers are generally wired to the ignition or stereo and turned on when the car is turned on. Due to some strange wiring, this just isn’t possible in the MINI Cooper. Some people use the cigarette lighter to power on their amplifier, but [war6763] wanted something that left his cigarette lighter free for other things. He built a circuit that monitors the cars built in USB input line and turns his amp on and off accordingly. The entire unit cost around $10.00. You can see the video demonstration after the break.

Dean Kamen’s Stirling Engine Car

[Dean Kamen]’s company, the people behind the Segway, have created a hybrid car that uses a Stirling engine instead of a standard internal combustion engine. Stirling engines are closed cycle, meaning heat is applied to the outside of the cylinder walls. They are generally more efficient than standard car engines, but haven’t been used much outside of industrial applications. We suspect that the drivetrain arrangement is similar to the Chevy Volt where the engine is used to charge batteries which are in turn driving an electric motor. This is different from modern hybrids that can have either electric motor or gas engine driving the wheels. The article is unfortunately full of classic [Kamen] hyperbole and minimal detail. He calls the Stirling engine “an insurance policy” for the electric car since it can recharge the battery. That’s right, folks. If you run out of juice, you can put gas in the car. I doubt many Prius owners will fall out of their chair over that. Being a Stirling engine, we’d be more impressed if you could charge the thing by rubbing warm toast on it.

TIME’s Best Inventions Of 2008

Attempting to put our past behind us as quickly as possible, TIME has released what they feel are the best inventions of 2008. While there’s some pretty wishy-washy lab-only stuff on the list, we’re glad to see a lot of cool hardware made the cut. Some of our favorites are: The Tesla roadster proving electric cars can be fun. IBM breaking the petaflop barrier with LANL’s Roadrunner. The Large Hadron Collider for getting everyone scared about physics all over again. Have a look at the list for many other tech highlights from this year.
