Re: Rotated Lisa Screen

Yup, you need to rotate the coil. Please be extremely careful when you are doing this. Keep one hand behind you, in your back pocket if possible. That way if your hand should touch something the power will go down out your leg instead of across your chest through your heart. A lot of volts lie back there, but fortunately they are at a very low amperage.
