Dr. Stiffler may call this thing a "1 wire circuit" but those in the know call it a variable frequency RF generator.
The coil you made.... RF Tank circuit.
Now all you have to do is inject a DC-rectified AC-decoupled audio signal into the output pre-amp's collector and viola! You've built an AM transmitter!
The LED lights up due to RF Excitation. You might be able to light up a small neon bulb or maybe even a small (4 inch) fluorescent lamp tube.
