    On our way back from her parents house Sunday in Houston, we decided to stop
    by a little antique mall somewhere between Houston and Austin. There I
    found an old Western Electric crank shaft telephone magneto still complete
    with the oak enclosure and in pretty nice condition. After testing it out
    on my stepson (he got a kick out of it), I decided I couldn't live without
    it and gave the lady $40.

    We got it home and Joe, my stepson seemed more interested in it than me and
    was hooking it to all sorts of little FM/AM radios, light bulbs and other
    little appliances. I also hooked it to a little test meter and saw it
    generates up to around 100v AC with a really good wind.

    I've been looking around the web for some ideas but haven't had much luck,
    so I thought I would drop this group a line. Does anyone know if this
    little novelty might have any practical use? If I were to rig up some sort
    to windmill or something to it to keep it spinning and connect it to a
    converter or some other power supply, is it possible to use one of these to
    power, say, a small ham radio?

    Hi Matt,
    You could power a lot of things with it. I don't know its limits but you
    could experiment to find out.
    Keep in mind, the more power you take from it the more power you need to put
    in.
    It will get harder to crank as the load increases.
    Have fun learning what it can do.
    Regards,
    Tom

    I *did* find that application on the web for this lil' shocker. I might try
    that, but here in Austin, I don't think the ground has very many night
    crawlers. Its pretty rocky. I also saw some folks talking about using them
    on fishing trips to "stun" the fishies. Sounds like an invitation for a
    hefty fine, hehe.
