Anthony Cerra and Russ Hakimiyan are the tag team that make up JoyStickers LLC . They came to Inventables online hardware store about six months ago with an idea to make a joystick for the iPad.

They started by creating some CAD drawings for what the device could look like, and then they started sourcing materials. They had to solve several sourcing and engineering problems including finding conductive rubber or foam materials, how to stick the button to the iPad, and how to package the whole device together. They found a few materials and vendors through Inventables, ordered some samples, and ran some tests. After a little bit of iteration they came up with a prototype that worked! Last week they came to our office and showed us their prototypes. The prototype has a simple red barrel
