I said I’d soon be posting another one of Chris’ KD4PBJ’s projects. This is a pic of the exciter he built lighting up a small fluorescent tube. It also lights up a CFL bulb. Notice that it doesn’t use any wires, it just radiates a strong field and the light just gets excited!
Another trick that one can do is use what is called an AV Plug or Avramenko Plug to detect the field. It’s really a half wave doubler. This is an LED, capacitor and diode soldered together and used as a probe.
