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.

    Ooooh, cool! You could even program it to display user-created messages! I think you can do the math.

  2. The first thing I thought of was as soon as Google sees it they’ll buy it. With Google Adwords revenue down, that would be a great place to sell more space.

    This can be taken to the next level to add 2d or 3d images, what a sight that would be!

    hey do you have the code you used for this?

    I’m working on a similar project and I’d like to see how you did it. Send me an e-mail or post a comment here. Looks awesome!

  5. Yes code sharing will be highly appreciative. Me too is working on a similar project.
