How often do you change the batteries in your television remote control? Yeah, basically never. But thats a tribute to how efficient the device is and not a reason to overlook this development.

Electronic Design Automation (EDA) tools allow you to draw out a symbolic representation of a circuit using a schematic capture interface, (sometimes) simulate it with a circuit simulator, and then finally lay out the circuit on a printed circuit board (PCB).

A simple game is always much more fun when it is spiced up with some cool electronics. The wooden tilt maze game has been around for a long time. This Marble Maze that is Remote Controlled using an Accelerometer kicks up the original game by allowing the player to interact with the game using a controller that moves the real game according to user movements.
