I need a diagram on building my own Cable tracer. It is a little different in terms of, it's not a point and whistle. It needs one (1) LED on for power. One (1) LED for pulse. It has to have a toggle switch for ON OFF and PULSE. it has to be powered using a 9vlt battery. How would i go about building it and if anyone could design a diagram it would be Greatly appreciated.![Smile :) :)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
