Load Sensing Exciter
Mixing up a few ideas from various people, this is a load sensing exciter circuit, with circuit diagram. When no wireless energy is being used, the LED on the circuit will flash, when a load is brought toward the coil or (in this case added) metal mass, the LED will stay on. The coil can be anything and, in fact, the circuit will run without anything attached, but the output is better, the better the coil – small Tesla towers work fine. The circuit is derived from Lidmotor’s ‘Penny’ blocking oscillator circuit, see his channel for the original. KyleCarrington then brought this idea forward with an idea of his for introducing diodes to his multi-oscillator experiments. LaserSaber first showed a diode connected to the Base of a transistor. So, this is a cross between many peoples ideas, to bring this circuit of mine ! It is currently used on my zero input voltage, Earth Grounded wireless energy set up (see my channel for related videos). Current consumption itself can be as low or lower than 39uA, as that is the total amperage that i’ve been working with recently. Note – Replacing the resistor with a 1 meg pot will allow tuning to different loads, coils and/or voltages.
