Alright guys, after a long ass time of trying to get one working, I finally had gotten this to at least a working and decently good form.
I made this with the intention of making this easy to mod for anybody, hence why it seems so simple.
I'm currently running out of day-hours to work on this project, so I figured I would open it up to the community.
THIS IS NOT PERFECT KEEP IN MIND, I DO NOT EXPECT THIS TO CHANGE THE WORLD LOL.
Anyways, before further a do, the pictures themselves will explain it.
Regards and Enjoy,
iMatt
------------------------------------------------------------
EXPLANATION OF MECHANISM:
------------------------------------------------------------
When the mechanism is inserted into (set) pen, the momentum from spinning will increase as the spinner does more tricks which have the pen move away from them which make the weight shift towards the back putting pressure on back spring.
When the direction is changed, the tension of the back-spring will push the weight forward into the barrel.
When the momentum is increased, the weight goes back towards the end.

Q & A
------------------------------------------------------------
Q: What Mod is the picture of the Dynamic displaying?
A: It is a Seven G3 Mod
Q: Do I need to use a Seven G3 Mod for this to work?
A: No, this mechanism can be fit into any number of pens
Q: What all known mods can this mechanism fit into?
A: Anything Regarding the G3(G3MX, G3MX², KuZu(with a little work), etc)
Q: Do all the parts have to be EXACTLY as the ones pictured?
A: No, there are multiple ink-tubes that can be used, so long as they can fit into the G3 ink-stopper. Your a community, Be creative
Q: Can this mod be retractable?
A: The interesting thing about this mechanism is that I thought this through when making it. Yes it can, it can also be used as a mechanical pencil if opted for.

nice mod imatt^^
but i dont really get it :/ -
Date: Tue, May 26 2009 05:24:13
Yeah. That looks very nice.
good job iMatt -
Date: Tue, May 26 2009 05:27:43
Wow this a beta? Can't wait to see what the finished product will look. Btw how does it spin? Like an mx?

Date: Tue, May 26 2009 05:30:07
ladies open your mouths because im about to ......
really nice matty!! -
Date: Tue, May 26 2009 05:34:37
LOL @ TEK XD
Anyways good stuff, imatt!
Hmm... I dont really get how the mechanism works, but it looks really innovative and revolutionary (psing wise)!
I'm guessing a sort of shaker but pen kinda thing? o_O
Really cool! I cant wait til the final product is out.

ok i get it now mk explained it to me.
it seems like it would be a hard pen to get used to though :/ -
Date: Tue, May 26 2009 05:48:06
Looks like a Retractable MX

if there is one....no wait.... different grip...

more like a Retractable Seven mod with the weight feature. lol -
Date: Tue, May 26 2009 06:15:01
from what I understand it isnt retractable?

Date: Tue, May 26 2009 15:25:45
the idea i think is that
if you're right-handed and you're doing a CW spin, the more you spin that direction, the more the pen adjusts to your spin and adds weight in the backcap thus increasing momentum
if you spin CCW, the weight shifts towards the front of the pen, thus again increasing the momentum
you could say that this is the "pen that spins itself once you get it going"
-> this is assuming you're spinning holding the pen in writing position. -
Date: Tue, May 26 2009 16:08:29
wow. that's amazing. how quickly does the weight transition? I wouldn't want to do a TA, have it shift, then do TA reverse and have all the weight at the wrong spot. If the weight doesn't transition quickly, then this could be very useful... can you adjust the weight manually, rather then just by spinning it?
Very revolutionary in the PenSpinning world... I just need a g3 and shaker. the cap is hyper gell, body rsvp, hgg grip+tip correct?
EDIT: looks like 3 HGG in the front with 2 different types of grips, which are not hgg. -

As I said before, the pen isn't perfect.
It has a learning-curve to using it. When you get past the feeling of the moving weight inside it spins really well.Handy Tips ->The Pen I put the mechanism in is just a Seven mod. Nothing special inside or out.
@Zombo, that would be correct
Date: Tue, May 26 2009 18:45:21My original design involved two weights which moved independently, on either side of the COG. It seems to me that this design would change the COG depending on the position of the weight, rather significantly. Does this occur and how significant is it? How difficult would it be (though I was planning to work on this anyway) to adapt this to a two-weight design?

This is part is kinda confusing for me lol. It's suppose to be "When the mechanism is inserted..." right? I got kinda confused reading that. This is a really nice concept. As Eburt said, would this change the overall balance of the pen and is the shift very noticable?Date: Tue, May 26 2009 20:15:02QUOTE (Thnikk @ May 26 2009, 02:15 AM) <{POST_SNAPBACK}>from what I understand it isnt retractable?
but would it work in a retractable mod?Date: Tue, May 26 2009 20:22:07so centrifugal force causes the springs to go outwards adding more momentum on the ends, and when it is stationary, the springs go back to their normal positions? :]

The springs themselves aren't what cause the weight to shift, its the weight of the Dr. Grip Shaker piece. That moves from side to side, with the springs pushing it as momentum changes. It you want to be technical, centripetal force pushes the weight into the spring, compressing it (until it is matched by the spring force).
P.S. I highly doubt this would work in a retractable mod. It would involve combining two very complicated mechanisms... and would be quite difficult.Date: Tue, May 26 2009 20:43:11Looks great
A truly innovative mod... or mechanism actually =P
Just wondering though, will it be possible using another inktube instead of a needle point inktube? since I believe that pretty much all the other parts are not too hard to get, will not everyone had a needle point inktube... Just wondering =P
Can't wait to see the final product ^^Date: Tue, May 26 2009 20:55:23QUOTE (Resonance @ May 26 2009, 04:43 PM) <{POST_SNAPBACK}>Looks great

...-runs off to make one-
this better be awesome imatt =P
just a couple quick q's
is it a g3 body + cap + lakubo grip in front?
im assuming you did the sanding and all that jazz, and used the electrical tape to hold the inktube in place?
and the inktube really has no functional purpose (writing-wise)?Date: Tue, May 26 2009 22:42:04@Eburt, I'm working on a dual weight system, the trouble is weight. I'm focusing on single side mods before double sided since those will be quite simple to implement. The dual system would consist of something like this
< = front of pen
| = begin of cap
> = end of cap
<=====|==>
There would be 2 springs about 2 notches that are glued together, they'd have to be quite small. Then have to be low tension, then high tension on the outer bound springs so the weight can push back fast enough to the center.
The weight's would have to be less weight in order for them to return to center in order for it to work.Date: Tue, May 26 2009 22:52:30Cool ima make this into a mp so i can impress the ladies
Date: Tue, May 26 2009 23:09:12brilliant
im really curious as to how a mod like this would spin but i guess ill have to make my own and find outDate: Wed, May 27 2009 13:19:21I'm guessing if you want it to be even more responsive you could do the following:
instead of 1 individual spring, you take 2 weak springs, put them on either side, push a washer that slides easily behind the weak springs, then put stronger springs behind the washer. The washer would prevent the springs from getting tangled up, while allowing more weight transfer at first, then because of the stronger spring the weight would go back to the center faster.
I dunno if this will work, just a suggestion.Date: Wed, May 27 2009 15:40:59QUOTE (Chief_Snake @ May 27 2009, 08:19 AM) <{POST_SNAPBACK}>I'm guessing if you want it to be even more responsive you could do the following:

It's not a bad idea, the trouble is noise. with a washer being generally thicker than the shaker tube the rattling will get VERY noisy, and it's not ideal for pen-spinning.Date: Wed, May 27 2009 18:56:51QUOTE (iMatt @ May 27 2009, 11:40 AM) <{POST_SNAPBACK}>It's not a bad idea, the trouble is noise. with a washer being generally thicker than the shaker tube the rattling will get VERY noisy, and it's not ideal for pen-spinning.
could you wrap the washer in something like teflon tape to reduce the noise?Date: Wed, May 27 2009 20:23:28QUOTE (iMatt @ May 27 2009, 10:40 AM) <{POST_SNAPBACK}>It's not a bad idea, the trouble is noise. with a washer being generally thicker than the shaker tube the rattling will get VERY noisy, and it's not ideal for pen-spinning.
thank you for the compliment I have seen plastic washers around, this might be able to minimize noise.. or you could cut the barrel of a pen in the shape of a washer, as this is also plastic. though putting teflon tape on both sides of a washer, then removing the tape from the middle is a good idea.

It wouldn't matter the material, no matter what, if there is a moving part inside on a flexible shaft that is in a very close proximity of a barrel it's going to make noise. Plastic washers also do not carry enough weight. They need to be of a metallic substance to have any effect on the overall momentum of a pen.

The mod CAN write if you extend it to. It's just a normal ink-tube.Date: Fri, May 29 2009 07:29:44wow nice mod.looks complicated to make.
Date: Mon, Jan 4 2010 08:29:55i have once try like the but i don't realy like it. the spring will also make noise
Date: Mon, Jan 4 2010 16:49:06its an interesting idea and great graphics on the write-up, I still kinda don't get it though (does the CG stay the same or the pen get lopsided once it shifts one way or the other?) Props for originality
it looks fun to try spinningDate: Sun, Jan 17 2010 19:49:29so I decided to try this and put it into my pen. I used a shaker shaft and 2 profile springs that I cut so they would fit perfectly into my rsvp body. I could feel the change in momentum as I spun. not much, but noticeable. I decided to take a video of it and go frame by frame seeing if I could see the shaker piece moving. I took a video at 60 fps, and selected a few noticeable frames.
at 100%, the distance from endcap to shaker piece is exactly 2 CM
this photo, at 100% is when the shaker shifted. the distance from endcap to shaker piece is 1.5 CM
distance from grip to shaker piece is 4 CM
the shaker shifted here. the distance from grip to shaker piece is 3 CM.
The shaker piece did shift, but just a bit. the whole spring wasn't compressed, but it did shift momentum. Use of a weaker spring and a heavier shaker like piece would mean more momentum shift.
It works. Just needs some more refinement.Date: Sun, Jan 17 2010 20:54:32you cant see shit thats incredably blurry
Date: Sun, Jan 17 2010 21:01:57you CAN see. just look closely. I would need a camera that can tape at a higher frames per second in order to get it crystal clear.
Date: Wed, Jan 20 2010 12:16:21Thats really brilliant imatt
but how come it can be only be used in g3 based mods?Date: Fri, Jan 22 2010 02:55:55QUOTE (iMatt @ May 27 2009, 09:39 PM) <{POST_SNAPBACK}>It wouldn't matter the material, no matter what, if there is a moving part inside on a flexible shaft that is in a very close proximity of a barrel it's going to make noise.

Well, wouldn't it work if you could find something to replace the inktube so it isn't flexible and then find small metal washers, then fill up the center with clay or some other similar material, then poke a hole through it so there's only a small hole for it to move?Date: Thu, Feb 25 2010 01:12:52QUOTE (Raine @ Jan 21 2010, 10:55 PM) <{POST_SNAPBACK}>Well, wouldn't it work if you could find something to replace the inktube so it isn't flexible and then find small metal washers, then fill up the center with clay or some other similar material, then poke a hole through it so there's only a small hole for it to move?
Sorry if this has been mentioned already, but you could solve multiple of these problems by having some liquid weight system. you could have a series of chambers in the pen (several washers, or even better, series of sieves or screens) and the oil would move through that. This design's response could be tuned by the viscosity of the liquid, the number of chambers, and the permeability of their connecting screens. Also, liquids are "dampeners" like in the shocks on your car - it wouldn't have the bouncing-around problems that the existing design must have with loose weights and springs. The springs motion is controlled by just kx meaning whatever the k constant is, it experiences movement directly proportional to force. Heres the problem with that, okay everything is fine if you're doing like a TA or Shadow, a level move. but when you do like a fingerpass, (pen is rotating vertically) the force inside your pen is swinging by as much as 2 g's, because of the earths gravity. penspinning activity (which is what we want to be controlling the dynamic weight system) however only produces an acceleration force = r(w)^2 where w is radians/second. Even if you can spin as fast as several revolutions per second, because your radius r is only centimeters it's nerfing your force that you want to be acting on. So you have this bananas signal to noise ratio (1:2?) acting on your weight, while your spring will be actually moving back and forth this much (or trying to), plus harmonics - it would feel like a party in your hands. I would love to see video. By dampening this action with a liquid, it's like you're integrating a sine wave or something, the +/- 1g swings will actually cancel each other out but the overall level of spinning would independently drive the weight of the liquid.
I dont know how to solve this problem though - how would you return the liquid through the screens when you're not spinning and you want the dynamic weight to move back.Date: Mon, Mar 8 2010 15:16:20@fletch kind of like a water bottle?...i dunno but this is really cool

not really unless your paper is very thick... The mech doesn't touch the inside of the barrelQUOTE (iamnotluck @ Apr 29 2010, 08:57 AM) <{POST_SNAPBACK}>are there specific tricks that this "mod" is good with? or its good with everything once you get used to it? im so trying this out!
I like it for infinitys... adds a whole lot of momentum on one side but you can sort of "feel" the weight shifting as you do the infinity.QUOTE (iamnotluck @ Apr 29 2010, 08:57 AM) <{POST_SNAPBACK}>edit: and how do you put the insert in??? does it have to be retractable?
I don't know what you mean by retractable? The mod isn't retractable in the first place.
