The purpose of the mechanical gyroscope project is to provide a method to directly demonstrate the rotation of the earth on its axis. Although the Foucault pendulum is claimed to accomplish this there is enough reports of Foucault pendulum constructions which did not precess according to the theory until several adjustments were made to call into question the validity of the claim.
FECORE’s efforts began with inertial measuring units or IMUs. IMUs are small electronic and mechanical devices found in many cell phones and other sensing devices. They are extremely sensitive and in fact they are not usable for many observations because they are so sensitive that small vibrations can’t be adequately filtered out. The other problem is that they always use a magnetic field sensor to constantly reorient the sensor. This was the reason the project shifted focus to a mechanical gyroscope.
Now let’s get up to speed on the state of the mechanical gyro.
Some observations in testing brought about some changes.
As the gyro was spun up to 3000 plus rpm it created a lot of wind. This air resistance slows down the flywheel after it was spun up by Dremel device. Stefan reduced the air resistance by encasing the entire flywheel with a close fitting plastic case.
Even with the reduced air friction the time of spin above say 6000 was less than 10 minutes and not long enough for any meaningful observations. Attaching a motor would introduce the problem of a wire to the motor which could influence drift or no drift. Stefan decided to have the motor driven by batteries which would also act as a counterweight to balance the weight of the motor.
The result of Stefan’s excellent workmanship is a very balanced gyroscope capable of 10,000 rpm.
In the picture you can see the coupling device between the motor and the flywheel. Below is a close up of it and a sample coupler to show the construction.Also on the motor support mount you can see the bolts used to attach the motor assembly directly to the gyroscope’s frame.
Recently Stefan has been trying to reduce some mechanical vibration at high rpm. Different motor mountings and motor to fly wheel couplings have been tested but more testing is needed.
To place the magnitude of this project into perspective it should be understood that prior to Loran for ocean navigation Sperry Marine made gyro compasses with the express purpose of maintaining rigidity in space as the boat turned and moved. This meant that once the compass was set to true north the gyroscopic action would keep it pointed there. This is the internal workings of a Sperry Mk 14.
These instruments are no longer sold by Sperry. The Sperry Mk 27 was last in production 30 years past. The cost of a refurbished Mk 27 is $71,000 which includes a 90 day warranty. And there is no guarantee that such a device is sensitive enough to measure a movement as small as 15° per hour.
We are thinking that Stefan can give a better warranty and the cost of donated time and labor is more in our budget. Thank you for your dedication Stefan.
