I gotta admit, this toy is exceptionally cool for a toy. Of course it would have been cooler with super low friction bearings all around in the gimbal but hey it's still a very nice toy/learning tool!

@@fromjesse I have one too and even knowing the physics involved, it still feels weird when it "pushes" against your hand when you try to move it in certain directions.

I'm not sure if it spins the full 25 minutes, but I can assure you that by the end of the 25 minutes it's just barely turning. The very slight imbalance of the flywheel causes shake which dissipates energy. This causes the speed to decrease rather rapidly at first, but as the speed decreases the energy loss due to vibration also decreases, so once it slows down to a fraction of it's initial speed, it does turn at a low speed for a very long time. Unfortunately, at that low speed, the gyroscopic effect is nowhere near enough to track earth rotation.

I have thought about that. I'm not sure if it would work or not. I have tried those for some other (heavier) experiments, but the weight was too great and it bent the points of the needle - and it was a proper clock bearing needle point. If I cannot get the roller bearings to work I'll definitely look at the feasibility of using clock jewels.

Yes, I need to replace the bushings with roller or ball bearings in the gimbal, which I plan to do! For the record, a gyrocompass is something more complex. It actually uses earth's rotation to point to true north without using the magnetic field of the earth! Very cool machinery. Also, I did use 3 old vintage aircraft heading-indicator gyroscopes to show earth rotation in a previous video: kzfaq.info/get/bejne/rrSJipt7vLO6f40.html Also, Stephen P. built a gyro from scratch which showed earth rotation: kzfaq.info/get/bejne/bdCDldCAqsDdYKc.html

"It isn't designed to show the drift". The only design you need is a low enough friction gimbal, and it definitely has that, or....... I think the 'compass' part wouldn't even work. I forget exactly how gyrocompasses work (they're an oooold invention).

For a toy it's not bad. But trying to use it as a commercial grade research gyro without realizing that it's just a toy would be a mistake.

Quite likely. That same technique is in use in mechanical gyrocompasses on ships all around the globe right now!

@@fromjesse very good video you made there too, I subscribed!!

Yup.

You are most welcome! Did you see my other video where I used aircraft grade gyroscopes to show 15 degrees per hour of earth rotation? kzfaq.info/get/bejne/rrSJipt7vLO6f40.html

@@fromjesse That's odd, because the Earth doesn't rotate or move. And there has never been any mechanical gyroscope showing that the Earth is moving. I have seen so many people try so hard, and even people try parlor tricks when they couldn't make the Earth move. I have even seen people place small weights on one side of the gyroscope housing to make it slowly precess, and then they were like "see! the Earth is moving".......very funny, but no the Earth doesn't move, or a mechanical gyroscope left on the table would show it......There's no need for tricks if it's really moving ya know.

@@dr.davidbannerf.e.s.6217 I didn't add any weights to my gyroscopes to cause them to show apparent drift. I didn't modify anything inside them between running them directly aligned and then at right angles to the North Star. You really should watch the video clear through: kzfaq.info/get/bejne/rrSJipt7vLO6f40.html The fact that some other gyroscope that has too much friction doesn't show apparent drift doesn't mean that mine doesn't. You mention a gyroscope that didn't show drift while sitting on a table, and you are probably referring to Rob Durham's video where he did just that. But if you watch his video carefully, he himself noticed a friction drag wire on his gyroscope which he didn't know what it was for. But it is there to cause some friction specifically to keep it drifting while the plane is sitting on the runway, watch right here in his video: kzfaq.info/get/bejne/a8d8a8SglazMdmQ.html See that wire? If he had removed that, he would have probably gotten drift! Besides, even without any earth rotation, an gyroscope with perfect bearings would have SOME drift, unless it was ABSOLUTELY PERFECTLY balanced. And none is absolutely perfectly balanced. So the fact that his didn't drift at all is proof positive that it did have some internal drag (obviously caused by that friction drag wire) -- so he needs to re-do his experiment with that wire removed. The gyros I used did not have that drag wire, and they also did not have the gear so they were very very much more freely moving. And all three showed a drift rate difference of 15 degrees per hour. Remember, the fact that a sticky gyroscope doesn't show earth rate rotation doesn't mean that it could or that others don't. It turns out that gyroscopes that do very freely move do show earth rate rotation, or apparent drift. In Fact, Stephan P. made one and he proved that the apparent drift was not from imbalance by changing spin direction of the weight: If the drift is caused by weights being out of balance as you suggest, then changing the spin direction of the flywheel would also change the drift rate. That's is a fact, you can try it yourself. However, when he changed the spin direction, the drift direction did NOT change, proving that it was being caused by something _outside_ of the gyroscope. kzfaq.info/get/bejne/bdCDldCAqsDdYKc.html

​@@dr.davidbannerf.e.s.6217can you show me people who put weights on the gyroscopes?

@@dr.davidbannerf.e.s.6217 - " because the Earth doesn't rotate or move." Except for the part where I have been HANDS_ON measuring earth rotation and curvature using fiber-optic gyros for almost 30 years. Modern aircraft use earth rotation to test the onboard fiber-optic gyros before a flight USING EARTH ROTATION. So modern aircraft measure earth rotation tens of thousands of times a day worldwide. this is proof that you are only repeating lies.

Thanks for proving that a slow rotation causes the Axle of the flywheel to Tilt and SHOW the slow rotation....IF the Earth were actually rotating. Thank you very much. Loved how sensitive and how responsive the Tilt of the Axle was, even though the lower bar didn't stay still, like it does with a faster Rotation.....It simply reflected and re-acted to the Slow rotation by TILTING the Axle orientation right in step.....Thank you so much for proving that a Precision Mechanical Gyroscope can and will show the Rotation of the Globespell should it ever become True.

@@dr.davidbannerf.e.s.6217 precision mechanical gyroscopes DO show rotation of Earth.

@@bendlyte You can stop pretending. None of them have ever shown any rotation. Ever. You can get one and find out.

@@dr.davidbannerf.e.s.6217 they have, you can see for yourself if you cared about the truth.

@@bendlyte None of them ever have, you can see for yourself, and you can get one and do it for yourself. Look----> kzfaq.info/get/bejne/fMecndyCqNapZYk.html

Yeah, the stock gimbal bearings are just umm friction joints. The upper ones are stainless in stainless, and the lower one is stainless in brass with a black plastic washer. Definitely a toy, but still pretty nice for a toy.

Mine do.

@@fromjesse Stop with the lies already.. Your video proved otherwise.

@@travybear2463 hey hey be nice! My video showed quite clearly that the earth is rotating at 15 degrees per hour.

@@fromjesse The earth is definitely not moving. If you put that same gyroscope into a helicopter or hot-air balloon that was hovering in place for an hour, it would show a 15degree movement even though you hovered in place and didn’t move an inch. 15degrees would be 1000miles in an hour on the globe model, that means the helicopter should be able to hover in one spot for an hour, earth rotate under you and then land 1000miles away. The gyro is simply measuring the movement of the sky above a stationary realm. Globe DENIED!

@@travybear2463 hey, instead of just dissing my efforts, why don't you tell us about some of the evidence you've gathered yourself?

> _The super precision gyroscope toy can't show the Earth's rotation because the Earth doesn't rotate..._ Well, but even if earth was rotating, it still wouldn't show it. Besides, earth doesn't rotate then why do REAL AIRCRAFT GRADE GYROSCOPES show 15 degrees per hour of rotation? kzfaq.info/get/bejne/rrSJipt7vLO6f40.html

Yeah of course, the software compensates any gyro drift based on the average direction of level based off of the accelerometers. If you look up the drift rate of the gyro chip in the iphone, it far exceeds 15 degrees per hour. The software has to slowly correct the gyro reading for drift. I dare you to try it with a gyroscope that is not in a phone, a gyroscope that does not have a built in accelerometer to correct the gyro drift. Globe accepted!

@@fromjesse It’s inside the closed system of a plane, not outside in the open on the wing. How would the gyro know the planes speed once at a cruising altitude?. The phone is in airplane mode and has no idea of its gps location. The gyro showed a level flight 10% of the way around a globe. That’s not possible on a ball. I am assuming you know about “rigidity in space”. The Gyro will stay in the position it is spun up at. Try this yourself. The globe does not pass the scientific method.

@@travybear2463 Yeah dude, your phone has tilt sensors in it too. They are called accelerometers. Look it up. It really does. What model of phone do you have? The app in the phone uses the tilt sensors to compensate and keep the gyro adjusted to level. Of COURSE it would remain level, because it's measuring the direction of down by using the accelerometer chip. And I notice you still haven't shared _your_ personal observations on this either.

@@fromjesse So why didn’t the tilt sensors register the 36 degree tilt after landing 2000 miles away? Flying 10% of the way around a ball is about 36 degrees. Zeroed at the gyro on the ground in Hawaii, showed a 15 degree tilt during take off, got to cruising altitude, and was then level for 2000 miles to Las Vegas… landed perfectly level in relation to the runway in Hawaii.

@@travybear2463 The only people I block are rude people and illiterate people. You've been reasonably polite but you're illiterate. You're not reading what I'm writing. The accelerometer chips in the phone compensate for change in angle based on the direction of down. The phone has gravity direction sensors in it dude! Grow up and read what I'm writing. Then go look up the specs on the gyro and accelerometer chip in your phone. You will see that the datasheet lists the drift for the gyro chip is FAR greater than 20 degrees per hour. You will know that the phone is using the gravity sensor to compensate for gyro drift. Being on a plane would be a very slow drift in angle, and the phone would just think it was gyro chip error drift, and would compensate. Please look up the data on your phone's gyro chip before coming back here and repeating your same false claims.

If you actually look up the phone, find out what model of gyro chip is in it, and get the datasheet for that chip and find out what the drift is, I think you'll find that it far exceeds15 degrees per hour, and would those be useless. But I encourage you to try it. Get a gyro-display app, turn off the accelerometer and compass, and use JUST the gyro and see just how badly it drifts when it's not depending on the tilt sensor or magnetic compass to stabilize it. Please check into it. You're just wrong. Cheers

LOOOOL. I love how people, like you, who know nothing and have never done anything in their life come along and dis on people who actually do stuff! But no, the toy gyro was brand new at the time and had not been dropped yet (LOL) and was very well balanced and just running very quietly. I had spun it up with it's little motor and it was working as good as it could. If you don't think so, get one and try it yourself!! If you really think that stainless on stainless pressure ball pivots have zero drag then you are just wrong. Go try it yourself before call stuff misinformation! You're the one spreading misinformation!

@@fromjesse I believed that because didn't see a 1:47 a micro cut (clock behind 6:23 -> 6:25) and then gyro was stoped. Where can I buy a real gyro in belgium please ?

@@bArraxas said: > _I believed that because didn't see a __1:47__ a micro cut (clock behind __6:23__ -> __6:25__) and then gyro was stoped._ Correct. Up to 6;23 on the stove clock the gyro was spinning. I was demonstrating the gyro effect. Then I paused the camera and stopped the gyro, then started the camera at 6;25 on the stove clock in order to show the bearing friction without the gyro spinning. Sorry if that confused you. > _Where can I buy a real gyro in belgium please ?_ How much money do you have to spend on it?

@@fromjesse 250 euros is it enough ?

@@bArraxas I'm afraid the best you could get for that is a "Heading Indicator" which is the type of aircraft gyroscope shown in this video: kzfaq.info/get/bejne/rrSJipt7vLO6f40.html They are not as perfect as is ideal, but if you are careful like I show in the link I just gave you, you can objectively test and see the 15 degrees per hour. But you have to be very careful and it is tedious. But it can be done.
