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. | |||

'''Final Project''' | |||
Beginnings - Disassembling an old stereo system and finding some interesting parts. We particularly liked the movement generated by the various motors, cogs and rubber bands controlling the CD player and the tape deck. | Beginnings - Disassembling an old stereo system and finding some interesting parts.
