Is this IT?

Your build looks great,Raj.
Maybe some batteries for weights? Or partial rolls of coins? Maybe some washers glued together? Good luck and thanks so much for keeping us posted.

The weights would be worth more than the wheel .

Major problem of synchronisation of weights' motions...
Precision of build questionable...

At long last, synchronisation of weights motions problem has been SOLVED, by changing the type of motions.

Remains the problem of precision build.
That should be solved by professional engineered build in due course.

The path of the weights has not changed: Aiming for heights versus width as usual, for constant unidirectional net torque provision.

Only the motion of weights has changed, to solve motions synchronisation:
From rolling on channels to SWINGING on strings both pivoting on larger drum wheel(1) and smaller wheel inside, geared and rotating at same speed on separate axles.

Learning to run... (OR swing as trapeze artists???)

I believe some explanation of the two pictures above is overdue:

1. My build attempts have always been to convince myself that there is something worthwhile in my concept/design.
2. My current build in the picture above, is only 11 inches diameter, too small to use all the 8 weights required in my design.
3. In my concept drawing above, there only two weights providing torque to the wheels, and six weights are torque neutral: one hanging just below the axle from the 12 o'clock position and five resting on the rim at 6 o'clock position.
4. I have carried physical concept testing using only four weights that matter most for proof of concept. See drawing and pictures with the four weights positions in red ink. With the four weights in these positions, the wheel turns instantly after released from rest.
5. To say the least, I am overwhelmed by this test result. But still I cannot say I am convinced 100 %.

So Now, I am concentrating in building a roughly 3 feet diameter concept testing prototype, incorporating the 8 weights as required, all by myself.
If the next result is as good as the one with only four weights, a BUILD by professional engineers will be more than warranted.

Well done Raj .. good show .. all the best in your pursuit for the truth.

Thank you Fletcher for your well-wishes.

We will all find the TRUTH, only when WE see a wheel working!

Slightly larger wheel build attempt.
Lacking build precision...Inadequate materials and expertise...

I am 100 % + self-convinced as from today that my Auto Hamster Gravity Wheel IS IT.

The picture shows my last AHGW concept testing build attempt, using:
1. two bicycle hubs and axles.
2. four cheap plastic hula hoops.
3. two one metre plastic rulers.
4. eight 12 in cheap children wood rulers.
5. some small screws.
6. eight cheap tennis balls for weights.
7. some strings.
8. some sticking tapes.

No more wheel searching from now on, and certainly no more build for me.

My AHGW working prototype will now be left to professionals, to be completed hopefully by year-end.

Hello, Raj.
So are you saying it's working? Or are you sure it will work with a precision build? I'm a little confused(as usual). Your home-build looks pretty good.You do come up with some great parts for your wheels.

raj · Post by **raj** » Sun Oct 09, 2016 4:16 pm

Hello Sleepy,
I am sure IT WILL Work if built as per drawing.
I have not been able to build my wheels with precise measurements.
Some centimetres longer on one place and shorter at other place, somewhere the rim is oval slightly here and there etc etc, making the wheels not perfectly balance on their axles, even before putting the weights.

But the prototypes showed the motions of the weights behaving exactly as per concept. That is one or two weights will provide torque on either side of wheels at any given times, and four or six weights will provide ZERO torque at any given time, so that there will be continuous net unidirectional torque on the wheels.

The motions of the weights is well apparent in my last picture.

This is for those who cannot understand my Auto Hamster Gravity Wheel concept:
1. the red circles show the weights positions on the counter-clockwise side of the wheels, producing negative torque.
2. the green circles show the weights positions on the clockwise side of wheels, producing positive torque.
3. the blue circles( four or five at the bottom at 6 o'clock) show weights producing neutral torque.
4. the red and green lines show the height versus width path of the weights.

The professional build of my Auto Hamster Gravity Wheel is now ongoing.
