Finding a junk VCR is pretty easy. Don't just throw it away- adapt the VCR's head into a spinning gyroscope! If you don't have an air compressor: 1) turn a bicycle upside down and petal it. 2) while holding the stationary half of the head, gently press the free half against the spinning tire rubber. Think of this just like two spur gears; the huge gear reduction (about 10:1)* should have the gyroscope humming along at a rotational speed comparable to what is shown here.

Vsauce: Any similarities between this video and Michael Stevens' recent video is entirely coincidental. I filmed this without knowing about it. I would like to take the opportunity to endorse that channel though! Vsauce1 is one of my favorite channels, and (imo) it has consistently produced some of the best content on the internet.
Please watch 'Spinning':
• Spinning

Giaco Whatever:
He also just made a similar video! I swear, I had no intention of being a copycat! Well, this one is also about making a spinner.
'99999+ RPM Fidget Spinner Toy':
• 99999+ RPM Fidget Spin...
~~~~~
*Assuming a 26" bicycle tire and a 2.5" VCR head (these measurements are diameters), we can multiply both of these numbers by pi (π) to get their circumferences:
26(π)= 81.7
2.5(π)= 7.9
If we then divide: 81.7/7.9= 10.3
Thus, every time the bike tire goes around, the gyroscope will go around over 10 times!
Notes:
-Circumference is how far it is around a circle.
-Diameter is how wide a circle is.
-π is how far it is around a circle when the diameter of that circle is 1. That's about 3.14.
-Parentheses indicate multiplication, for example: 2(3)= 6.
Oh, and the head spinner becomes cold.
Thanks for reading ;)

Oh the hundreds (maybe thousands) of VCRs I worked on over the years. I threw away (recycled) the last couple dozen video drums I had when I closed my shop in 2013, But I did strip and save the bearings and the locking collars. I kind of wish I'd saved one now. Those parts you're aiming the air at are the actual videos heads, in case you were unaware. I always enjoy your videos. Thanks.

Without looking at any comments and not scrolling down so I’m unadulterated in seeing anything I would say cold when using compressed air. Pretty cool. I need to scavenge an old vhs player and get to shredding something that I have yet to operate on. I never thought I’d be tearing up or down old electronics but not that I’m old and torn up myself it’s really all that I have and it’s pretty cool actually seeing how things are built and function and some things have really awesome parts and then there’s trying to figure out what some parts can be re porpoised 🐬 for or if they are just really neat gizmo toys.

The VCR head works just like a tape recorder head with a couple of exceptions. There is a lot of information in an audio/video signal, so the engineers had to get as much information as possible into the smallest unit area of the tape. To accomplish this three things were done: 1) The head is is very small in order to leave a small track of magnetic information behind. That allows the machine to leave many many "stripes" per linear inch of tape. 2) The head rotated at a very high speed to read as many lines as possible each second. 3) To understand the next part two physical properties must be defined: Cohesion (koh-HE-zhun), and adhesion (ad-HE-zhun). Cohesion is how well one thing sticks to something else, and adhesion is how well somethings molecules stick to each other. A layer of air molecules stick to the rotating drum through cohesion, and adhesion causes a layer a little bit thicker to stick to the first layer. This means that a cushion of air is stuck to the surface of the rotating drum. This means that the speed of the drum determines the thickness of the air layer on top of it. This is balanced against the tension of the tape, and it allows the tape to move over the high speed drum floating on a cushion of air! That allows the tape head, and the tape to be very close together, so that a lot of information can be packed into a small area. Also at 4:46 the speaker is pointing at the heads for the circuit boards with a pencil. The part that sticks out past the surface of the drum is the actual head. (I told you they were small!) I hope this helps.

Great video! I don't know what it was that kept us so entertained as kids with gyroscopes, but it was so cool to balance them on your fingers and such. My favorite part of this video was the fact that you mentioned that you still use your VCR. Same here, I have a couple of them and the reason is, is because there are a ton of movies (some pretty cheesy) that were never released in DVD format or any other format for that matter. There a few documentaries on the VHS craze in the 80s, when Mom and Pop stores were everywhere. My favorite is Rewind This. I suggest you check it out. You won't regret it.

Some time last year my grandparent's neighbour asked me to take a look at her VCR, and just trash it if I couldn't fix it. Probably a clever way to save herself a trip to the tip. I couldn't fix it since my knowledge of repairing electronics is just looking for swollen capacitors or burned components, but I did also spend a while playing with the head. I didn't think of using it as a gyro but I replaced one of the bearings with that retaining collar, which was strangely a very precise fit with bearing holes, and used it as a spinning top.

Microwave has 2 magnets like that, no metal to pry off, and they're more powerful. =) (Just be careful of the cap!) Wouldn't something like braided fishing line work better for the gyroscope since you could layer more wraps onto the shaft? (Honestly don't know - never had one as a kid & seems silly to buy one as an adult.)

About your trivia question... it has to do with the compressed air. Basically, compression squeezes heat out of it and decompression then leaves it ready to absorb heat from whatever it comes into contact with. :)

For the gyroscope forget the string what you can use is a tire preferebly small bike tires and with that if you run the axle part of the axle along the bike tire while turning the bike tire you can literally kick it at high speeds! Just be sure to lube the ends before doing so as the gyroscope uses friction instead of rolling element bearings! XD

If you want to get a really good pull on a gyroscope try 3 to 4 feets of braided fishing line. Its really strong and very tiny so you will get many tours around the shaft. The more tours the more force you can apply at pulling so ... MORE SPEED! :)

i think it heats up when you use it because how can it coll down when its already at ambient temperature. your adding mechanical energy to it while it being transformed to heat, the wind it creates tries to dissipate the heat but it should not go below ambient temperature, there is no refrigeration process

I thought it would get cold because when compressed gas decompresses it becomes cooler
@pocket83

Yep. Even though the bearings generate heat in the form of friction, the fast-moving cool air sweeps away the heat (and even removes some after that). The result is cold metal.

When the ball/magnet spins at an angle, even though it's touching the glass at one point, wouldn't there be a lot of friction because the point that is touching wouldn't be on the axis perpendicular to the axis it's spinning? I imagine would be like a wheel spinning on the spot, which explains why it slowly moves(the ball can't get traction to move quicker but it shows the point that the ball touches the glass is moving very quickly) which id imagine would slow down its spinning speed.

you could connect led's where the read/write heads are connected instead of cutting that ribbon cable off of the stationary part of the drum that powers the coils in the ferrite plates inside that are for wireless power transfer to said heads With the addition of a 74HC595 or a 74HC164 serial in parallel out chip (or several of them), and a few other parts (capacitors, resistors, maybe an inductor and such) you would have the "hardest to build" part of a persistence of vision displaying gyroscope! That my friend, would be ultimate! To those "fidget spinner" knobs.... build something! Fidgeting gets you NOWHERE!

Would it not Generate heat from the friction? Is what i shall assume to the hot or cold question, you sir have asked in this moving picture with the integrated audio, that i have just witnessed from the beginning to end. Yes! It is quite fascinating. UNLESS!! The cause of the rotation on those PCB pieces that you have described as a sort of Fin as to which you used to spin the object using the wonders of compressed air has the properties to thus also cool the spinning object creating a slightly windy breeze just enough to cool down the metallic parts JUST enough to keep it from heating up? Perhaps? Hopefully a detailed answer as to why this may be, or not to be, will be explained to us all. So Yes! We can all become a little more "smarter" as they say..... Do they not? I'm sure we all are looking forward to the justification to this intriguing predicament that you sir, Mr Pocket83 have put upon us all with such magnificent thought and puzzling wording to make the query seem quite more puzzling than it seemingly appears. I hope all can recognize and master the nonsense wording I have put here in this judgment segment of this unbelievably complicated, impossible gibberish English I have typed out on here today.

Questions: With the high speeds of the VCR head, blown by the air compressor, how much voltage / current could the vcr head produce if used to produce electricity? In like manner, if the threaded together ball bearings were made of different materials, and blown to those high speeds, how much current / voltage could it produce? Would the created voltage / current be less than, equal to, or more than the energy needed to blow either of the above to those high speeds? fyi: The ball bearing question above is envisioned as the bearings made of magnets / magnetic materials.

Hot, friction causes heat right? Rolling friction of the bearings, and friction from the air resistance on the outside
@pocket83
@pocket83 7 лет назад
Yes, but wrong! Friction does cause heat, but this thing still gets cold. Why? Because the compressed air quickly sweeps away all of that heat, and then some. Compressed air is air that is in a settled-down state; heat is simply molecular motion, so in order to cram lots of it into a small space, it has to give up its heat (energy). In scientific disciplines, this idea is known formally as the _Ideal gas law,_ which is usually expressed mathematically as PV=nRT, where P,V, and T just mean pressure, volume, and temperature.

Physics is confusing. But it's also possible to understand. Friction (from kinetic energy) does cause heat, which should make it feel warm, but this thing still gets cold. Why?

I used to like quite a few of Grant's videos, but lately...he's kinda more like a mash up of KipKay (since moving to RU-vid, though he did have some half decent stuff for a little while here) and Crazy Russian Hacker...all fluff and show, no meat...but when half the population is vegan, that's the kind of content that sells.

whoa, I think you misinterpreted me there. Let me be clear: that guy makes the world a _worse_ place.

I think we're coming from the same place, though you may be coming from deeper and darker than I am at this point.

Ryan, I was responding to mr. Justifyed there. We're on the same page. These comment strings are just confusing- why can't they just post chronologically?!

Joof My guess would be more from the compressed air than the physics. Air friction from spinning would normally suggest increased heat, but he's using compressed air, which has a greatly lowered temperature due to the air being more dense. Packing more gas molecules into a smaller area means they can't move as freely, reducing their movement and therefore heat energy. This is different than those pre-packaged CO2 canisters, those are filled with CO2 cooled to liquid state, they pressurize as they warm back up.

I'd rather put it that the air rapidly loses its temperature when it decompresses.

its the opposite actually. compressing the air makes it warmer. think of a fire piston. it gets colder when it is blown out the nozzle because it expands to atmosphere pressure and it takes heat energy from its surroundings to do so.

The air when it's compressed heats up but the hot air is inside the compressor tank and it cools down eventually. But when it decompresses it cools down even cooler than it was before because it lost it's heat while it was in the tank.
