In school years ago we used to use something for circuits. It was like a box thing with crocodile clips on it, you connected one clip to positive and one to negative and could increase or decrease the power output which went through the circuit. I cant remember the name of it ::). Anyone know what its called? and where i can get one for cheap? Cheers
