Here’s another simple schematic, based on my Super Simple Three Dial, and using the amplifier from the Wishing Machine posted yesterday. The Aerial is an optional extra, and is in no way necessary. You could experiment to see if it increases your output. As before most of this can be done with crocodile clips if you aren’t used to solder and soldering irons. I would add that it would be a good idea to secure and insulate the crocodile clips on the pins of the potentiometer, so that they are secure from pulling lose, and that the tips of the other leads don’t touch creating a short circuit.
