	Experimenting with controlling this motion using various sensors (photo cell, audio jack) alongside a relay. Sending a signal to the relay would cause the motors to change direction and make the CD tray ‘dance’.

	Final Project		'''Home made variable resistor'''

			An attempt to make ‘permanent salt’. Noticing that, upon adding different amounts of salt to a solution, I could alter the resistance of a circuit and therefore make different sounds, but that after some time this effect lessened as the salt dissolved, I tried to make a non-soluble equivalent. Using shredded tin foil, I placed hundreds of tiny conductive pieces of metal into the dissolved salt solution. When shaken, the effect of collisions would cause the circuit to make different sounds.

			Wanting to continue with sensor controlled motion, we looked into paper mechanics. After some initial tests, it became clear that we needed a lot of control over the motor in order to preserve the paper. Therefore we replaced the relay with a servo motor and used an Arduino to set the style of motion. We also decided to use an Infra-red sensor so that our mechanism could be triggered by movement.
