There is a need of collaboration to build it completely.

Hello Sm0ky2 sir,
 your and other members guidance is important now.

Dear Webby Sir,
Did you mount the counterweight on the" Flip" side of arm?
As when I mounted both mass on a single side of arm the input was not good but when I mounted the counterweight on the flip side of arm then input was good.

Dear Webby Sir,
The device will work as per your expectation if we use a lock mechanism to hold counterweight after tilting the device.this lock mechanism will work in this way that it will be locked at the time of tilting the device after tilting it from 90 degree( as there is no problem up to 90 degree due to counterweight).
So that the counterweight will be lifted upside due to falling mass when the falling mas hit the upper side of tube.in this way the device will get momentum.
The lock system will be designed in this way that it will be unlocked due to energy falling counterweight as the counterweight will get momentum so as the whole device.
Now your main problem is solved.
As far as I think there will be need of maximum 5 joule energy to this lock mechanism.

Dear Webby Sir,
You are correct that lock doesn't need any energy but I want to tell you that it will work to prevent the falling of counterweight after tilting the device from 90 degree so that the counterweight could move up to provide momentum to the device and decreasing input and increasing leverage.
But you are expert so I think you better than me.
Thank you sir.

Try rotating your degrees of freedom more into the vertical domain.
At no point should the center of gravity drop below the axis.


If the arm is 90-degrees facing the right side:
Draw a vertical line where the arm is.


Now raise the arm until the center of mass
Crosses that line near the 45-deg or so
The weight will fall left.
Balancing the arm to either side of this line
Should be the operation of the device.
The ball falls twice.
Left then right

Dear Sir,
As per sketch there will be need of tilting the device just few degree more so that the ball could fall down.
There will be a lock mechanism which will work to prevent the counterweight up to that time when ball hits the upper part of tube .
The lock mechanism will work in this way that it will be unlocked due to impact of counterweight.

Dear Sm0ky2 sir,
As per my calculations it must work.if there is something wrong then please clarify it.
The scale length is 2 meter.
There is a 2 or 4 meter long tube.
Let's take tube length 2 meter.
This 2 meter long tube is mounted on left arm of seesaw in middle so it's 1 meter part is above fulcrum and 1 meter is below fulcrum.
A 10 kg.ball is resting at the bottom of the tube.
Now counterweight.
After calculating distance from fulcrum the counterweight will be 14.4 kg.to balance the seesaw as the distance of ball is 1.44 meter from fulcrum as the ball is in rest position in the tube.
Now the seesaw is in balanced position.
But I will take counterweight 20 kg.due to this excess counterweight the seesaw will be in tilting position at 90 degree angle.
Now when I lift up the seesaw then I will not have to calculate the input energy of  the 1 meter distance of tube which is mounted below fulcrum as I have added mass in counterweight.
Now calculate input using mgh formula
Mgh=10*10*1=100 Joule
But calculate output as ball will fall down from 2 meter height
Mgh= 10*10*2=200 Joule
Ball will again fall down from 2 meter height at the time of reversing
Mgh=10*10*2=200 Joule
So total output is 400 Joule but input is 100 Joule.
The very interesting point is that it is not important that the device must complete one cycle as ball has completed one cycle.
See the link.you can see momentum in the video.

The latch-pin is a nice addition, as it release the ball when you need it to

Dear Sm0ky2 Sir,
See the sketch.as per sketch the tube length is 2 meter.
It is mounted in middle with left arm.
A10 kg.ball is in rest position in this long tube  below 1 meter from fulcrum.
The counterweight is 20 kg.
I have taken a ball as a counterweight in a 1 meter long tube.
The long tube rest 1 meter part is above fulcrum.
Now as per my calculations input and output.
If seesaw is in horizontal position and ball is in rest position below 1 meter from fulcrum then counterweight will be 14.4 kg.
But I have taken 20 kg counterweight.so seesaw will be in Vertical position.
Now input will be 100 Joule
As ball will be lifted up only 1 meter.
But output.
At first ball will fall down from 2 meter height
So output=200 Joule
Ball will again fall down from 2 meter height
So output=200 Joule.
So total output is=400 Joule
But there is more output from counterweight.
When ball will hit the top of tube at the time of tilting then the counterweight ball will also jump in the tube and it will again fall down.
If 20 kg.ball jump 75 cm in the ball then the output will be 150 Joule.
So total output will be 550 Joule.
There will be a great advantage if counterweight ball jump in the tube as device will get great momentum.

The device get great momentum if counterweight ball jump in the air in the tube as the counterweight will become massless up to that time when ball is in air in the tube.
In this way the counterweight will also work as a output.

I did an experiment to know the feasibility of device .when I drop the ball then the counterweight ball is bouncing in the tube to provide leverage.
This experiment is proving difference between input and output.

Only as an oscillatory device.
When turned in a complete circle,
The energy gained in the top half is lost at the bottom.


also the balancing seems important, it needs to be heavier on the
counterweight side, so at rest, the ball is above the axis.
otherwise, the effect is mostly lost.
But when it’s too heavy, the down-motion of the ball is fighting the
counterweight.


Still working on a demo model, it looks like the arm with the weight
should be angled, opposite to the angle formed by the end of tube to axis.
this way the machine can balance with both weights at the axis.
