    Mains current detection

    MP, I can think of one way, using a small toroid core (scavenged from some junk) and make a transformer. The saw motor hot (live) will serve as primary and some thin insulated wire will be the secondary. I don

    How to increase reactance in a coil of few turns?

    thrival, Welcome to this community, If you switch the mains voltage in to the 12 turns no wonder you are blowing the fuses! This is close to short-circuiting. You need to puls the feed or have a much higher frequency at hand if you are gone get away with it. If you want to change the ratio don

    rechargeable battery pack AM/FM radio

    Mark, The diodes are 1N5821 or similar and the resistor depends on the mA rate of the NiCad pack and the voltage at the input. The input voltage can vary from 12.7V (12V battery in rest) to 14.4V (alternator full charge). Sometimes the cells are marked trickle charge 50mA or some rate that is...

    detect broken wire without removing the rubber

    Keile, Audioguru, How about using high voltage, then a spark will jump the break. A spark is easier to detect and no need to jerk the cable. This will of curse be lethal to any circuits connected to the cable but if you disconnect both ends before the test, why not? Ante ::)
