I wonder if you could help me. For testing a prototype a require a simple circuit board designed and made. I require: a board that can be powered by 9v to 25v. that it creates an oscillating current. Has a knob on that can adjust no oscillations / frequency from between 1Hz to 150KHz to 150 Ideally the board will have two wires that the power is connected to and two that the oscillating current is created to. I require no box. I only require only one of this. I invite offers to make this for me. I found this which may help: http://www.electronics-lab.com/projects/oscillators_timers/007/index.html Thanks.
