A simple and easy capacitive sensing tutorial
posted November 3 2010 20:44.46 by Giorgos Lazaridis

For many of us, capacitive sensing is kinda "space-technology". Looks like that Joby Taffey had something like this in his mind when he decided to use his capacitive sensor with his launchpad...

Its a convertible!
posted November 3 2010 5:25.18 by Giorgos Lazaridis

It looks like that Lyshco is more than a fan of racing games, such as the Dirt 2 rally. But setting up the cockpit was too time consuming for him. So he made a convertible cockpit. The outlook is an Ottoman style sit. But when the wife is away, the top opens and the cockpit is ready for the driver! There is no bucket seat, instead an old school plastic chair, but is fine for the moment. The steering wheel is mounted on the 2 sides of the cockpit, and the pedals (which are chopped out of their original plastic base) are fixed onto the base. The size of the cockpit is 1500 x 500 x 500 (size in millimeters) and it is made of MDF wood 18mm. Here is the post he made for this project.
