    Hi Alun, I am very honoured to have a circuit named after me! ;D Good job Alun! As Audioguru says a diode for protection and the circuit will run DC-motors too!

    Hi Jamie, You could try a small steel castor wheel on the end of a steel rod. The rod must be suspended for easy movement up and down (low friction) linear bearing kind. A couple of sensors near the top end of the rod will control either a couple of micro switches (roller type) or if you like...

    Oh I see, way back we called it a fuzzbox I guess. But of curse no processors was invented at the time! Are there any delicate parts in there like Audioguru suggested

    LM317 Variable power supply

    Hi Enigma, The regulator should also be backwards bypassed by a diode to play it safe. If the voltage is set to 5volts and you connect a cap that is charged to 15volts for example you can blow the regulator. Another scenario could be while running a small motor at high rpm suddenly turn down...

    Here you can see an old monitor inside which have only partially shielded coils on its neck. http://www.electronics-lab.com/action/gallery/inside_crt/ In the newer ones it looks more like this:

    Relatively new, looking for some basic answers.

    I think that in the dessert the dry sand or dry earth for that matter will not be much of a shield. As I said a BIG coil should work and the more current the power line carries the more power is induced in the BIG coil! ;D
