Super Angry Birds is a force feedback USB controller for Angry Birds that simulates the feeling of a slingshot. All the controls found in the game are available in this device. You can control the pull, angle, and of course trigger the special power of the bird.
We hacked a motorized fader found in audio mixing consoles to create the force feedback. Basically, the way we achieved this is by drawing a force curve and storing the values in a table, then we send the current position of the slider through the table and extract the value to send to the motor that applies an opposing force.
We programmed in Max/MSP and Arduino. For controlling the hardware, we used an Arduino-based microcontroller called Music.
