Remote Bike Mountain

The Remote Bike project, caught our eye today. Inspired by “cliff hangers” on the tv show “The Price Is Right”, [atduskgreg] has built his own version. In this version, the bike on the mountain makes progress, or slides back down the mountain based on the speed you pedal.  If you maintain your target speed long enough, you make it to the top of  the mountain and win. The RPMs are gathered from a stationary bike using a hall effect sensor, then piped to an Arduino that controls the bike via a stepper motor and string. That seems fun, and a decent alternative to biking through google maps or something. We have to wonder how long this would be amusing though. Then again, when you’re on a stationary bike you are usually just using a timer or a heart rate monitor anyway, so this is pretty cool.

Digital BMXing Through San Francisco

[Alpay] sent in this project he did recently. He was hired to produce a kiosk that would stand out to the kids at the event. He chose to make a bike riding game utilizing open source hardware and software. There was some thought put into what interface to use to make it easiest for people to just pick up and use. The ultimate decision was a simple one. Use real handle bars from a bike. As for software, they used Blender, the open source 3d creation program. The actual control is done via a pair of Arduinos, an accelerometer, and a pair of XBee modules.

He notes that blender is fully capable of accepting the serial input from the controller, but they opted to have the controller mimic keystrokes to make life easier on the developer, as well as make the controller usable on more games. Maybe if enough people ask really nice,  he’ll release the source code for the controller.

Another Stationary Bike VR Rig

[Shingo] shared his implementation of a stationary bike as a virtual reality interface. This is similar to the Google Street View setup we covered a week ago but goes a few steps further. They patched into the bike computer to pick up rotation of the bicycle wheel and added an accelerometer for directional control. This setup can navigate through Street View but the video after the break also details an interface with Google Earth and even the ability to navigate through Second Life, following your avatar as it bikes along with you. The use of a wearable display is far superior to something like the SurfShelf and really gives you a goal other than just some cold-weather exercise. So take this idea, patch it into a wearable computer and you’ve got the exercise setup worthy of the future world we’ve been promised.

Unreasonably Bright Bike Light Apparently Hunts Deer

ureasonably-bright-bike-light

[Jukka] wanted a bike light that wasn’t afraid to go into the woods during the dark winter. He put together a lamp that uses eight 3 Watt LEDs to pump out 1680 lumens (english translation). The high power LEDs were mounted on a large aluminum heat sink and use lenses to optimize the beam of light. The system uses a 2 amp driver board that he assembled himself. Power is provided by sixteen AA Nickel Metal Hydride batteries that are housed along with the driver circuit in a water bottle.

This more than doubles the output of the last bike light we thought was too bright. Where will this lumen-arms-race stop?

Vintage Video: Computing Across America

roberts

in 1983, [Steve Roberts] packed up a Tandy 100 laptop and a 5-watt solar panel, fleeing suburbia on his recumbent bicycle on what would become a 17,000 mile journey that forever cemented his place in the geek pantheon…not just as a technology hacker, but as one of the preeminent “life hackers,” pursuing his own dreams on his own terms and inspiring others to do the same.

In this 1989 video, recently unearthed by Hack a Day, [Roberts] reflects on the first 16,000 miles of his voyage, detailing some of the technology that went into his then-current ride, the Winnebiko II.

700 Lumen LED Bike Lamp

700_lumen_bike_lamp

We’ve seen bright bike lamps before. This one caught our eye because it needs a heat sink while in operation. [700lumenLED] built a super bright light for his bike that features an aluminum enclosure and heat sinks to protect the LEDs against overheating.  Some nice work was done incorporating the 12v battery into a bike bottle with the power switch and a dimming potentiometer attached to the bottle cap.

Zelo, The Improbable Wooden Trike

The earliest bicycles were made from wood. Nearly two centuries later, some garage tinkerers still turn to this most traditional of materials for their own creations, since welding one requires experience and tools beyond the reach of many. Resembling Gilligan’s Island props, the resulting bikes are both artistic and great fun, but not very practical for real use; often heavy, ill-fitting or lacking durability.

[Boris Beaulant’s] birch laminate Zelo, on the other hand, has cleaner lines than anything you’d see in an IKEA showroom. Not content with an ordinary two-wheeler, he’s tackled a three-wheeled recumbent trike, which requires even finer tolerances. Two months and over 1,300 miles later, the trike is still rolling strong through the French countryside, proving its mettle as legitimate transportation and not just a garage novelty. [Beaulant’s] build log (Google translation here) offers some insights into the development of this masterpiece, starting with prior woodworking projects (furniture, rolling toys and a children’s bike) and finding clever solutions to problems such as creating a mold of his own back for a custom-contoured seat.
