This project is a mounting system that adds mechanical tilt control to the iPhone. The unit uses two servo motors to move the iphone on the X and Y axis. The system is controlled by an analog joystick and an Arduino board. It can be used to play accelerometer-based games on the iphone. [via]

This is a robotic arm paired with a stepper motor to move it back and forth. It grabs up a sharpie pen and receives automated commands to dot out pictures.
The Sharpie Dotifier uses 5 servo actuators to move the arm up, down and to grip objects. The robotic arm is on a wooden stage which is moved back and forth via a threaded rod. The stepper motor turns the threaded rod so that the stage moves back and forth. Because the motor moves in precise steps we can reliably track the movement back and forth and always know where the stage is.

CHEX is a perfect device for testing CCPM servo setup. This device allows you to connect 1-3 servos simultaneously. It can be used as a servo signal generator for testing electronic speed controller (ESC) without using a transmitter and receiver. Also, this device can be used to check other RC devices as shown in the features below.
