Hyperloop Powering???

yea you can.

cant describe the motion though, but its far to fun...

its not complicated, your hands just kinda go in circles. for weave ones your hands go in same diretion circles, and butterfly ones (not very good at these) opposite directions.

you just have to kinda feel it.... good luck

Garthy was chatting to me once about whether or not it was possible to move your hands apart and together to power the tangle.

Like those old toys with a bit of string through a disc ~ by pulling in and out the disc tangled the string a little more each time so eventually it was going really quick.

Pulling on the poi mid tangle certainly accelerated the heads (the radius of the circle decreases => velocity increases)

But when moving your hands back in, I'm not certain you can keep it all going. Although there does seem to be a way of linking that in to the hand rotations so that you kinda drop the tangle down a little to move your hands in so that you can power it up again by pulling outwards.

I'd like to believe that you can.

¦m¦

re: powering the hyperloop by pulling your hands apart...

i have found that the trick is to make lots of little pulls, rather than a big pull that speeds them right up. i think you pull in time with one full rotation of both poi. get your rhythm from the poi, dont try and impose it on them.

This is something I got over christmas and I think I understand it enough to offer some sort of explanantion.
When doing the 'winding' you are effectively making the center of rotation at a point alng one of the poi bodies, therefore one poi is spinning normally the other is slightly isolated.
On my socks however the constant spinning in the same direction means the nexus creeps towards one side, which I can compensate for by making some little tugs but the have to be propperly timed and I don't quite understand that bit yet
It's taken my maximum hyperloop length from about 6bts to well over 30bts though (after that my arms get tired)

Funny I find the winding no problem but find it really hard to go back to letting them spin by themselves, they always seem to stall.

Absolutely right
I got it this weekend, I think I was just comming out of the winding at the wrong moment so the poi had uneven momentum and one would always catch the other up.
Now I get it

Do you think that once im able to do hyperloops then il understand wth our sayin? lol!

[quote="Rev"] I can do simple airwraps now.. I ahvent been able to do those in a long time.. amazing how the simple things elude us after a while...

that's weird... that's not what a powered tangle does.. I'm thinking it works that way because of the uber-tiny strings.. can you do that with sticks on strings that small?

the vid you linked shows you actually pulling the weight around... this isnt a luxury that you have with other poi...

you can't power a tangle by pulling your hands apart either... its a misconception.. the poi spin faster because the diameter is smaller, not because they gain anything.. which is why they slow down when you spread them apart.. in fact you lose energy going each way... the friction lost to the strings, unless you have uberslick string (perhaps like the yoyo (nylon?)), affects the transfer each way..

when we talk of powering we are using a technique close to what you do in your yo-yo vid.. the difference being that we crank the poi... you don't pull anything... this might be hard to follow.. the difference in what you do lies in the fact that you are having a direct effect on the poi head.. you directly manipulate the weight of the poi, hence the pulling.. when we do it, you can't pull the weight of the poi.. I couldnt do it with my sock poi, and I by far couldnt do it with sticks and laces.. yo-yo string isnt doesnt create the same tension.. though I don't know if tnesion is the right word.. basically there is slack in your yo-yoing.. and you take up the slack and it pulls the yo yo around.. this is in large part to the slick string.. with other poi, like laces, and socks, there is a lot of friction there, so you can't just pull out slack that you leave behind.. and thus pull the head around.. (though in a way I wish you could).. also the string naturally holds a lot of tension.. there is no slack to pull because from tangle to poihead, it acts like a rod.. its this particular aspect that we have to focus on.. since our strings aren't as slick, the friction allows for a grip in the nexus (the focal point of the tangle).. thus when you turn your hand axis (ie hand <-tangle-> hand) out of time with the poi axis (ie poihead <-tanlge-> poihead), it creates torque.. with the right balance of pressure, this torques allows you to crank the poi axis.. basically it grips tight at the point of the tangle and forces it to turn..

I don't think you can do this with yo-yo's without a LOT (Like great-heap'em-bunches-and-alot) of skill.. because the slick strings mean you would have to have such perfect balance in your control of each of the 4 points (hand x2 and poihead x2)...

I'd love to be wrong on all this.. but in all my experience, this is what I've found.. I'm not saying your method isn't completely in applicable, I'm just saying it wont work with most forms of poi, since you need both the poi almost out of momentum (for the slack string) and rpeferably a slicker string.. in order to perform your method you must keep doing it, and don't carry much momentum after you stop.. whereas what I'm talking about is kinda like a merry-go-round.. once its gets going (ie the tangle is formed) you can givve little taps to keep it going each round.. (ie little spurts of cranking..) ans so when you stop, it still spins liek a normal tangle, not a dead one.. also when you get the cranking down, I think it takes a TON of skill to constantly crank.. mine tend to cranks on fractions of the circle, rather than the whole circle, unless the poi are spinning slow.. the faster they are, they harder it is to lock that groove.. and it slips more than it cranks..

anyway.. I hope that helps..
