I would like to build a demo board that incorporates a Series Fed Hartley Oscillator. It should be able to incorporate two metal probes (used as the adjustable capacitor) that will change the output frequency. The metal probes will be inserted into materials with different dielectric constants.
1) Design the circuit and provide a eagle compatible file to be provided for manufacturing and demo board.
2) Provide a [login to view URL] simulation of the circuit.
