Excellent story, the weird things that happen in a hypnogogic (half sleep) state, eh.
It's always quite fascinating how something so simple as a few pivoted weights and some springs can be tuned into such a complex and interactive state. Bet the math and/or computer model shows no gain, as expected - sometimes the real world can become too complex to compute.
Thanks again for sharing. Nice not to have to deal with all the spooky paranoia for a change :) Will have to built a good solid version to really see what's going on. Great stuff!
: : Hi grim,
: : A very interesting design that addresses centrigugal force problems associated with most radial moving weight systems. Well worthy of further examination, IMO. Thanks for the extra info.
: : Do you think this design would continue to self rotate indefinitely provided it was made strong enough to withstand the pounding?
: : Regards, ovyyus
: Hi Ovvyeus
: Very possible. As long as the weight got lifted off the bottom, the wheel became topheavy and unstable. The "Tarzan" weight at the top pitched it into a sideheavy direction.
: As Brett suggested long ago, make a "four", but I got off on another tangent trying to do JB's smooth operation. The drawing you have sat idle on a floppy for a few months.
: Honest truth, got up 5 am,, no coffee, started building this. Did you ever do something half asleep, like your hands are working and you are just an observer? Put it together,
: woke up the household with its noise, and drew it up after coffee and .jpg'ed it to Brett. Both REAL excited until it began to tear itself up, both models. Just kept our traps shut
: and geared up for redesign.
: You are correct, it utilized the centrifugal force to help reset itself.
: You'll are welcome to play with it, it's a pain in the butt to time, but it works, and can hurt you if care is not taken!
: Three pounds of lead turning in a blur, around a 15" perimeter.....
: Best to you and all,
