When I was younger, I absolutely despised going on errands with my parents. I was driven out of my mind with boredom and would constantly complain that I wanted to go home. I wished that I could have something to distract me, and my parents did too.
The Cell Phone Case Racers are miniature race cars stored on the inside of a cell phone case! Parents can carry these with them on errand runs, and give them to their kids to play with. The phone case will also function as a remote controller.
The cars would be constructed from plastic or acrylic, and have small electric motors and antennae. They will also have hooks on their hoods to attach to the phone case. The remote controller would also be made out of plastic with an Arduino based control system.
