Remember that the pyramids are OLD. In the time of Cleopatra, the pyramids were as ancient as Cleopatra is to us. They come from a society that hadn't even discovered the wheel. I'm not saying aliens did it. But considering the pyramids were the tallest structures on earth until the construction of the eiffel tower, and the most massive structures until 1984 (weighing more than things like the Hoover Dam), there's more to it than simple human ingenuity. Whatever led to the creation of the Great Pyramid was not seen again for most of human history, and is only being rivaled in very recent times.

I am an ex RAF Avionics engineer and used to service gyros like this one in the mid 1970’s, that were fitted to RAF aircraft to ensure Radar Scanner stabilisation. The gyro had to be bolted down to a bench to stop it “walking” on power up and power down. The gyro had to be left for 30 minutes after power off, to ensure it had stopped spinning before we could unbolt it from the bench. If you did not let it stop spinning, it would be uncontrollable if moved could cause a lot of damage, not only to the equipment but also to property and personnel. The gyro is housed in a spherical cover, of which you can only see half in this video. Thanks for reminding me.

As a Avionics Technician I always love to see stuff like this getting some attention. Aviation is full of so much cool tech and mechanisms. Through modern aircraft use Ring Laser Gyroscopes, not mechanical ones like this.
My dad’s an avionics tech/engineer, picked up the trade in the military, and when he got out he would go to Africa for work. When he was home we would chat for hours and hours about planes and helicopters and how he kept them going where they needed to be and how he’d rebuild all the instruments and rewire all the avionics throughout the aircraft’s. definitely mad appreciation for the boys that keep us flying straight man! Good on you!
@truehighs7845 Technically their unaffected by earth rotation. When mechanical gyro's they spin up, they fix themselves to a fixed point in space. This way, the aircraft can always tell its orientation. That's the basic. I hope I didn't make it more confusing.
It is used in airplanes and in sea going ships and space ships. It establishes an orientation in space, as to what is up and what is down.

Current avionics technician here, and can absolutely appreciate the beauty of this. Learned all about these and serviced them in tech school and how far we've come with laser gyros is 'pretty cool'
Crazy to think that we have miniaturized this technology that we have it almost all on our electronic devices and take it for granted. Plus we now have GPS.
The one on your phone is much less stable over time. I'm pretty sure your phone tries to recalibrate multiple times per day. The ones on spacecraft have to remain accurate over several weeks. Edit: the ones on your phone appear to be just specialized accelerometers, measuring torque on a small mass as the phone moves.
@@nunyabusiness5075 yes, but what Im trying to say is, we have a gyroscopic system on our smartphones the size of a grain of rice, 60 years ago, these things weighs hundreds of pounds. Sure it may not be as accurate as these systems, but still
and gps is its own kind of pure fucking magic sattilites talk to the reciever and go "hey this is the sphere this receiver is in" and then another one goes "this is where i think it is" and you repeat this about 5 times and you get a fairly accurate representation of where you are. Theres also RAIM, which monitors the integrity of the information of each satellites, and god think about Wide Area Augmentation System, which uses a bunch of ground stations across the US to find out where the sattilites think the ground stations are, which sends that information to a master station which corrects the ground station's actual location to the GPS's idea of where it is, to find out exactly how to correct for it, which is sent to a geostationary satellite which is then sent back to the reciever, which is then accurate to like, a 3m cube. fucking INSANE.
That gyro is running at 86,000 rpm. Once it's placed azimuth, to magnetic true north level surface it's run up to speed. It gets 3 voltage sources Two are rechargeable batteries internal and One always on external power supply.. Some ships use them on satellite and radar antennas to always being in line with the satellites and the radar gives the best scans relative to the plate of the ocean
Clarification: It's not the entire thing that spins at that rate, only a set of flywheels inside the black canisters in the central frame in the gyro. The whole thing rotates so the thing in the middle can stay in one fixed orientation.
Sorry to be pedantic, but it's Tektronix. I used to repair and calibrate these when I was much younger.The old valve-driven models had ceramic connection strips with little U shaped 'buckets plated with silver and needed special silver-loaded solder for any repairs. Yes, they were beautifully made bits of kit.
Nah, thing of beauty sure. Incredible work. It's not art. That doesn't make it inferior or superior, just different. Art's use is in expression & communication, a form of human communication of themes given characterization. This is not made as a form of expression, so it isn't art. That doesn't make it any less beautiful or incredible though.
One of my first jobs was lacing wire harnesses for electronic systems using lacing cord. It was indeed very satisfying work, then came plastic cable ties cheaper, faster, reversable but oh so ugly.
@@BeachsideHank Agreed, I use tie-wraps currently & consistantly have to wire looms to this standard . It is quite the norm. It is a shame that most cases, the wiring looms will never gert seen or appreciated once a unit is finished & buttoned up! (ROV electronics pods etc). What amazes me here, is that these looms & noticably the breakouts to the connector blocks, survive such high G-forces of the spinning Gyro's!
I bought one almost exactly like this at a garage sale a decade ago for $20. One of my favorite possessions. Only after watching a documentary on the Apollo program did I understand what it did. It established a starting point of reference that an entire trip could be extrapolated from using gyroscopes to create an electrical feedback from. Incredibly clever. You should have described some of its purpose.
That's exactly what I wrote in the foreword for my dissertation for my final exam:"if we forget the technical achievements of the past, we cannot achieve the dreams of tomorrow. We need to stand on the shoulders of giants...." The visual craftsmanship in this device is humbling 🤟
Pretty awesome find. It uses extremely accurate servo outputs from this gimbal system to an artificial horizon indicator. Older systems obviously used analog signals, this is a 3-axis gimbal setup to get feedback for pitch, roll, and yaw. "Newer" systems went away from analog deflection and opted for digital feedback. It could be represented digitally with only 8 bits, the most significant (MSB) being 180, 90, 45, 22.5, 11.25, 5.625, 2.8125, 1.40625, these added up are approximately 360 degrees being represented with 8 bits, obviously this could be even more accurate with 8 more bits of accuracy, but not necessary for an artificial indicator.
@@somethingelse4424something inside the chunk in the middle is spinning which makes it resist changes in orientation. The outer rings are there to let it stay in position as the plane moves, their orientation is measured, and those measurements translate into the pitch, yaw and roll of the aircraft. They also have accelerometers to go with this and together the two can be used to determine the planes position using dead reckoning (tracking movement from a known position). Nows the part where I tell you that the pilot only thinks they're flying the plane....
No, the weight is spun up under a vacuum, to reduce airflow drag, to eliminate as much gyroscopic precession as possible. The signals sent back as feedback drive a servo (the actual indicator) as a form of "error" meaning the indicator is not where the gyro signals say it should be, so it "chases" that error as it corrects and nulls the signal out (no more error) aka no need to move anymore.
You said a while lot of stuff fur being clueless to what modern systems use. We haven't used mechanical gyroscope in decades. They are all ring laser gyroscopes and have been fur quite some time.
Yes, but slide rules , fascinating as they are, are limited to APPROXIMATIONS, and had no built in functions like roots or powers that a modern calculator produces instantly. Using a slide rule and simple machine tools to built something of this level of precision and beauty is just mindboggling
Something that I will always admire. Such masterpiece of human mind restores my faith in humanity. Looking at this sophisticated mechanism I always imagine not only the amount of efforts and genius ideas that were put in this to create it, but also a few times greater number of ideas and efforts that were discarded during the process. And this impresses me even more.
Both RNAV and VNAV are GPS navigation types. GPS is obviously satellite based and does not require the use of gyroscopes. What you are looking for is what's called an IRS/INS gyro.
The craftsmanship and meticulous processes of the old masters is what drew me into art! The glazing technique used in oil painting plays with the refraction index of the transparent(or translucent) medium being used to thin the paint. Light passes through the built up layers of paint before being reflected back to the viewer which leads to optical mixing of colors - the perception of color resulting from adjacent colors; this occurs in the viewer’s retina. Paintings that use this technique tend to have very lifelike qualities because your eyes are doing the mixing in real time instead of just using an opaque layer of a pre-mixed hue from the palette.
Your words nearly brought me to tears and ultimately moved me to research and learn something I would likely have never known or ultimately loved. That's friggin art... or something equally awesome. Thank you.
This isn't just a work of art, but a monument to the insanity and creativity of the physicists, mathematicians and engineers who worked out how to solve the problems of navigation using mechanical gyros and electronics and possibly magic. It's beautiful to those who understand the significance of it.
Optical gyros blow these out of the water but for the time this was a huge achievement and enabled airplanes and ships to have dead reckoning in the middle of the night and bad weather.
*@PhysicsDuck* Wow, I can see that spinning in a display inside an art museum. Pretty damn fascinating, interesting, and cool! Appreciate you showing this. 🤝🏻
Each part of a gyro is mounted in a device called a gimbal, and ultimately a gimbal can only allow so much movement.The center gyro hits the edge of the gimbal and bounces off it -- also called gimbal lock. In the movie Apollo 13, this is the same "Gimbal Lock" they were talking about. When a gyro hits gimbal lock, even for an instant, it loses its reference frame and no longer knows its spatial orientation. And for any astronauts relying on that gyro, gimbal lock of the flight guidance system is quickly followed by death, as the spacecraft no longer knows where it is, how fast it is going, or where it is headed.
kudos to Elmer Sperry, (1860-1930) Elmer Ambrose Sperry invented gyroscopic-guided automatic pilots for ships and airplanes that have also been applied to spacecraft.
Engineering is a beautiful art. It’s like a combination of composing a symphony (bringing each tiny part into a harmonious whole) and sculpting (manipulating materials with respect to a specified 3D space). It’s 2 artistic philosophies in one practice!
Very well put, I'm looking forward to seeing more of what you have to share. I'm glad to have found your channel, and my socks will also be subscribing.
I acquired one of these years ago. Of all my oddities that i have to 'show-and-tell' , it is by far my favorite. VERY old early generation American ingenuity! Everything you stated about your example piece is exactly how i feel about mine. 👍
And this.... Has been shrunk down into something the size of a crumb. Your phone likely has one inside of it. It's also what allows quadcopters (Drones) to maintain stability.
Drones don't use gyroscopes, they use accelerometers (which measure acceleration). You can find information, but found with no spinning. 3 accelerometers, 1 for each axis. Usually microscopic mass spring systems (mount spring mass spring mount) where the mass' position is measured using electronics and then uses a lot of math to get orientation, velocity, etc. Edit: I wanted to clarify for anyone else that reads this, since a lot of people will imagine there's a really tiny spinning thing in there phones. The reason this gyroscope has been "shrunk down" to fit in your phone is because we don't use gyroscopes at all, we use microelectronics.
@@in4dalols247 And I think that even undersells just how small accelerometers in phones are. The little springs are literally etched in at the micrometer scale. Anybody going on a Wikipedia hunt, the term you're looking for is "micro-electromechanical systems" or "MEMS accelerometer"
When I studied engineering, I was shocked to find out that most of the basic principles upon which machines work, force, acceleration, heat, steam, combustion, sound, light, electricity, were all discovered by observation and brain power, centuries ago.
Right to even come up with this Idea to orient a spacecraft or whatever else is pretty wild but pretty simple at the same time. Takes a clever person to come up with this solution. And we’re absolutely standing on the shoulders of giants. When I watch ww2 and space race documentaries it blows me away.

I think they're both great. I feel like the point of the video is to just point out how artistic the STEM field can be. Not to shit on other types of "art" as you seem to be doing.
Its very impressive that these were used inside ordinance to keep them "guided" to target. The variety of applications these were used in is beyond impressive. True talent.
We often think of older people to have been simple and not as smart as we are but then they made stuff like this almost a 80 years ago. No computers no cnc no nothing just wanting to make stuff and then making it. We should bring back this culture.
if you push and practice your mind can do amazing things. 55 years ago i learned to add numbers as fast as i read them. far faster than i could enter them in a calculater. i had a job where i added numbers about 3 hours a day. after a few months i noticed i knew the answer to short sets of about 5 numbers before i entered them, so i worked on being able to do longer strings. within a few more months there was no limit. that 3 hours turned into 20 minutes. once the numbers got over 6 digets i didn't trust myself but i would just subtotal and do more. sadly for me i lost that due to extreme illness and high fever 23 years ago. if i could do that most can.
Which is why I despise the current era of nitwits who denigrate our elders and ancestors and think anything before 2005 is so barbaric and backwards it shouldn't exist.
I wonder what the minimum integration error was on the best gyroscope based inertial guidance system. Was it better or worse than the MEMS accelerometers in smartphones?
Way back when, I worked on a stellar navigation system that had a CEP of 6 feet/hr. If I remember correctly, after 8 hours of flight, the largest error was ~20 feet.
I'm pretty sure that the best mems would fall short of what a real gyroscope can do for long term accuracy. Mems is just a couple accelerometers. Gyros lock the ring orientation to a reference. Though mems can't get their rings stuck so that's a plus... Navication gyros also get fed data from other systems to update them. That said, with how accurately you can measure with ring laser gyros, you can now go hours without feeding corrections to an INS
@@joshuacheung6518 "Locking" vs differential measurements is a pretty meaningless difference when your lock drifts more then your integrated differential signal. Nothing beats a good laser though, and those are also differential measurements.
Great presentation! I completely agree that our forefathers were amazing in what they accomplished! “Raw talent and shear force of will”! Very well said! Love it!
Idk why my eyes are wet 😭. You will have to be an engineer to understand how FUCKIN difficult it is to come up with a design like this, that too in an era without CAD and calculators. Just, all I can say is I am touching the feet of those legends.
Space Engineers is what first taught me of this. A device that can spin you and stop your spinning without gravity in a vaccuum. It's been implemented in so many vehicle building games since then
Cable management is like putting paint on a canvas.
Imagine how complicated those electrical rotary joints are with all those different signal wires
Or if you work where I work, like throwing spaghetti onto a bowl. :-)

You can hear the amount of respect and appreciation you have for those craftsmen before us
Current avionics technician here, and can absolutely appreciate the beauty of this. Learned all about these and serviced them in tech school and how far we've come with laser gyros is 'pretty cool'
Sweet for sure! I retired from the Air Force and have helped pull many ins systems out of aircraft but.never saw the inside! Thank you
I may have been one of those guys you helped pull the ins system out.
But that was a long time ago in places far, far away.
and us back shop guys appreciated you flightline box pullers and wire chasers!! PMEL
Crazy to think that we have miniaturized this technology that we have it almost all on our electronic devices and take it for granted. Plus we now have GPS.
I believe it got replaced by Ring Laser Gyroscopes rather than miniaturized versions of this.
The one on your phone is much less stable over time. I'm pretty sure your phone tries to recalibrate multiple times per day.
The ones on spacecraft have to remain accurate over several weeks.
Edit: the ones on your phone appear to be just specialized accelerometers, measuring torque on a small mass as the phone moves.
@@nunyabusiness5075 yes, but what Im trying to say is, we have a gyroscopic system on our smartphones the size of a grain of rice, 60 years ago, these things weighs hundreds of pounds. Sure it may not be as accurate as these systems, but still
@@Kandralla And nowhere near as accurate and need constant updates to correct itself.
and gps is its own kind of pure fucking magic
sattilites talk to the reciever and go "hey this is the sphere this receiver is in" and then another one goes "this is where i think it is" and you repeat this about 5 times and you get a fairly accurate representation of where you are. Theres also RAIM, which monitors the integrity of the information of each satellites, and god think about Wide Area Augmentation System, which uses a bunch of ground stations across the US to find out where the sattilites think the ground stations are, which sends that information to a master station which corrects the ground station's actual location to the GPS's idea of where it is, to find out exactly how to correct for it, which is sent to a geostationary satellite which is then sent back to the reciever, which is then accurate to like, a 3m cube.
fucking INSANE.
No is not art. It's a machine built for a practical reason. If you consider it art doesnt mean its creators built it as art

@@Physicsduck How old is this gyroscope ???
@@jangounchained5279really, some background info would’ve gone a long way
Wet beaver 🦫 bruh
I do that too
That gyro is running at 86,000 rpm. Once it's placed azimuth, to magnetic true north level surface it's run up to speed. It gets 3 voltage sources
Two are rechargeable batteries internal and One always on external power supply..
Some ships use them on satellite and radar antennas to always being in line with the satellites and the radar gives the best scans relative to the plate of the ocean
I had a stroke trying to read this
Clarification: It's not the entire thing that spins at that rate, only a set of flywheels inside the black canisters in the central frame in the gyro. The whole thing rotates so the thing in the middle can stay in one fixed orientation.
You should get that checked out. Op was pretty understandable.
Why 86000 rpm? That's surprisingly close to the number of seconds in a day 86400.
@@Pow3llMorgan ok ,i knew there was no way it would hold togather
Things like this convince me that most technology now is magic, just very highly understood and repeatable
Only a select few have the privilege of truly appreciating the beauty and artistry of engineering.
Absolutely a work of art. So too is a Techtronics Oscilloscope.
Back in the '60's as a young tech, having a Techtronics Oscilloscope was like wearing neck Jewely amongst us wage slaves.
Sorry to be pedantic, but it's Tektronix. I used to repair and calibrate these when I was much younger.The old valve-driven models had ceramic connection strips with little U shaped 'buckets plated with silver and needed special silver-loaded solder for any repairs. Yes, they were beautifully made bits of kit.
Nah, thing of beauty sure. Incredible work. It's not art. That doesn't make it inferior or superior, just different.
Art's use is in expression & communication, a form of human communication of themes given characterization. This is not made as a form of expression, so it isn't art. That doesn't make it any less beautiful or incredible though.
@@alanmumford8806 And if I recall they furnished a small spool of that special solder mounted inside the cabinet.
@@pubcle art can be anything.
That wiring harness is beautiful in its simplicity and neatness
I noticed the same. It's satisfying
One of my first jobs was lacing wire harnesses for electronic systems using lacing cord. It was indeed very satisfying work, then came plastic cable ties cheaper, faster, reversable but oh so ugly.
@@BeachsideHank Agreed, I use tie-wraps currently & consistantly have to wire looms to this standard . It is quite the norm. It is a shame that most cases, the wiring looms will never gert seen or appreciated once a unit is finished & buttoned up! (ROV electronics pods etc). What amazes me here, is that these looms & noticably the breakouts to the connector blocks, survive such high G-forces of the spinning Gyro's!
My OCD gives this the stamp of approval
I bought one almost exactly like this at a garage sale a decade ago for $20. One of my favorite possessions.
Only after watching a documentary on the Apollo program did I understand what it did. It established a starting point of reference that an entire trip could be extrapolated from using gyroscopes to create an electrical feedback from. Incredibly clever. You should have described some of its purpose.
Great information! It's so very aesthetically pleasing.
That's exactly what I wrote in the foreword for my dissertation for my final exam:"if we forget the technical achievements of the past, we cannot achieve the dreams of tomorrow. We need to stand on the shoulders of giants...."
The visual craftsmanship in this device is humbling 🤟
Pretty awesome find. It uses extremely accurate servo outputs from this gimbal system to an artificial horizon indicator. Older systems obviously used analog signals, this is a 3-axis gimbal setup to get feedback for pitch, roll, and yaw. "Newer" systems went away from analog deflection and opted for digital feedback. It could be represented digitally with only 8 bits, the most significant (MSB) being 180, 90, 45, 22.5, 11.25, 5.625, 2.8125, 1.40625, these added up are approximately 360 degrees being represented with 8 bits, obviously this could be even more accurate with 8 more bits of accuracy, but not necessary for an artificial indicator.
So does each axis spin under servo power?
@@somethingelse4424something inside the chunk in the middle is spinning which makes it resist changes in orientation. The outer rings are there to let it stay in position as the plane moves, their orientation is measured, and those measurements translate into the pitch, yaw and roll of the aircraft.
They also have accelerometers to go with this and together the two can be used to determine the planes position using dead reckoning (tracking movement from a known position).
Nows the part where I tell you that the pilot only thinks they're flying the plane....
No, the weight is spun up under a vacuum, to reduce airflow drag, to eliminate as much gyroscopic precession as possible. The signals sent back as feedback drive a servo (the actual indicator) as a form of "error" meaning the indicator is not where the gyro signals say it should be, so it "chases" that error as it corrects and nulls the signal out (no more error) aka no need to move anymore.

You said a while lot of stuff fur being clueless to what modern systems use.
We haven't used mechanical gyroscope in decades. They are all ring laser gyroscopes and have been fur quite some time.
Beautiful statement that defines many practices such as soldering, construction, medical ect.
Superb Engineering.. Both mechanical and electrical.. Indeed a work of Art.
They had slide rules. Thanks for tribute to my dad. He worked for Whittaker Gyro in the 50/60’s
Your Dad is one of countless unsung heroes.
Yes, but slide rules , fascinating as they are, are limited to APPROXIMATIONS, and had no built in functions like roots or powers that a modern calculator produces instantly. Using a slide rule and simple machine tools to built something of this level of precision and beauty is just mindboggling
@mipmipmipmipmip quality of craftsmanship. Everyone traded quality for quantity these days.
Did Whittaker make actuators for fuel control as well?
My dad started from USAF into MIC 1960, American Aeronautics, NASA, Rocketdyne, General Dynamics, Honeywell Ratheyon....engineers are bad ass!
Your tribute is poetry, a touching reminder of all those things that we only miss when they don't work.
Brings a tear to my eye, honestly.
Something that I will always admire. Such masterpiece of human mind restores my faith in humanity. Looking at this sophisticated mechanism I always imagine not only the amount of efforts and genius ideas that were put in this to create it, but also a few times greater number of ideas and efforts that were discarded during the process. And this impresses me even more.
That is specifically a RNAV Gyroscope or VNAV gyroscope and its probably from an old airliner.
Both RNAV and VNAV are GPS navigation types. GPS is obviously satellite based and does not require the use of gyroscopes. What you are looking for is what's called an IRS/INS gyro.
And these days RNAV and VNAV are all GPS with a laser gyroscope to back it up. We truly are standing on the shoulders of giants.
RNAV and VNAV are digital but they used to use a gyroscope for GPS homing. Its a thing of the past now though
The craftsmanship and meticulous processes of the old masters is what drew me into art! The glazing technique used in oil painting plays with the refraction index of the transparent(or translucent) medium being used to thin the paint. Light passes through the built up layers of paint before being reflected back to the viewer which leads to optical mixing of colors - the perception of color resulting from adjacent colors; this occurs in the viewer’s retina. Paintings that use this technique tend to have very lifelike qualities because your eyes are doing the mixing in real time instead of just using an opaque layer of a pre-mixed hue from the palette.
That is pretty frickin cool lookin and obviously pretty complicated too. Neat!
Thats absolutely beautiful.
Love art and the hard sciences
Your words nearly brought me to tears and ultimately moved me to research and learn something I would likely have never known or ultimately loved. That's friggin art... or something equally awesome. Thank you.
I'm sincerely thankful you enjoyed it :)
Thank you for this video. Those men made civilization possible. We don’t think of them enough.

This isn't just a work of art, but a monument to the insanity and creativity of the physicists, mathematicians and engineers who worked out how to solve the problems of navigation using mechanical gyros and electronics and possibly magic. It's beautiful to those who understand the significance of it.
Optical gyros blow these out of the water but for the time this was a huge achievement and enabled airplanes and ships to have dead reckoning in the middle of the night and bad weather.

@@PhysicsduckCrazy thinking this same technology was used for the V1 buzz bomb. It is a complicated and precise work of art.
stunning....i love the analog/electro mech stuff!
Positively gorgeous piece of art, that is!
As an engineer, WW2 era technology always fascinates me
All topics always come together somehow to form something truly amazing
I love when the one part is spinning then suddenly stops and reverses direction.
Banging off the stops. The center gimbal can only rotate 180 degrees.
Each part of a gyro is mounted in a device called a gimbal, and ultimately a gimbal can only allow so much movement.The center gyro hits the edge of the gimbal and bounces off it -- also called gimbal lock.
In the movie Apollo 13, this is the same "Gimbal Lock" they were talking about. When a gyro hits gimbal lock, even for an instant, it loses its reference frame and no longer knows its spatial orientation. And for any astronauts relying on that gyro, gimbal lock of the flight guidance system is quickly followed by death, as the spacecraft no longer knows where it is, how fast it is going, or where it is headed.
@@doctechno2241 Thank you for explaining that. That's the question I immediately had watching this video.
Beautiful and intricate designs that we will hinge on far into the future, the work of our predecessors are truly magnificent ❤
kudos to Elmer Sperry, (1860-1930) Elmer Ambrose Sperry invented gyroscopic-guided automatic pilots for ships and airplanes that have also been applied to spacecraft.

Engineering is a beautiful art. It’s like a combination of composing a symphony (bringing each tiny part into a harmonious whole) and sculpting (manipulating materials with respect to a specified 3D space). It’s 2 artistic philosophies in one practice!

As a Mech Engineer. I think this is a thing of beauty.
Love all you giants out there! Keep standing tall 🫡
And this.... Has been shrunk down into something the size of a crumb. Your phone likely has one inside of it. It's also what allows quadcopters (Drones) to maintain stability.
Drones don't use gyroscopes, they use accelerometers (which measure acceleration). You can find information, but found with no spinning. 3 accelerometers, 1 for each axis.
Usually microscopic mass spring systems (mount spring mass spring mount) where the mass' position is measured using electronics and then uses a lot of math to get orientation, velocity, etc.
Edit: I wanted to clarify for anyone else that reads this, since a lot of people will imagine there's a really tiny spinning thing in there phones. The reason this gyroscope has been "shrunk down" to fit in your phone is because we don't use gyroscopes at all, we use microelectronics.
@@in4dalols247 no they use one at least mine used one although it was a helicopter
No, those are a set of flat accelerometers that are processed into faux gyro signals...
@@in4dalols247 And I think that even undersells just how small accelerometers in phones are. The little springs are literally etched in at the micrometer scale. Anybody going on a Wikipedia hunt, the term you're looking for is "micro-electromechanical systems" or "MEMS accelerometer"
And before someone says ring laser gyros can be really small, aint nobody putting that in a phone. Too expensive. And larger than a crumb.
When I studied engineering, I was shocked to find out that most of the basic principles upon which machines work, force, acceleration, heat, steam, combustion, sound, light, electricity, were all discovered by observation and brain power, centuries ago.
Right to even come up with this Idea to orient a spacecraft or whatever else is pretty wild but pretty simple at the same time. Takes a clever person to come up with this solution. And we’re absolutely standing on the shoulders of giants. When I watch ww2 and space race documentaries it blows me away.
Always learn everything I can from my old teacher, Mr. WetBeaver.

You finally got my sub with that one, 10/10
Its very impressive that these were used inside ordinance to keep them "guided" to target. The variety of applications these were used in is beyond impressive. True talent.
We often think of older people to have been simple and not as smart as we are but then they made stuff like this almost a 80 years ago. No computers no cnc no nothing just wanting to make stuff and then making it. We should bring back this culture.
if you push and practice your mind can do amazing things. 55 years ago i learned to add numbers as fast as i read them. far faster than i could enter them in a calculater. i had a job where i added numbers about 3 hours a day. after a few months i noticed i knew the answer to short sets of about 5 numbers before i entered them, so i worked on being able to do longer strings. within a few more months there was no limit. that 3 hours turned into 20 minutes. once the numbers got over 6 digets i didn't trust myself but i would just subtotal and do more. sadly for me i lost that due to extreme illness and high fever 23 years ago. if i could do that most can.
btw to do that you can not break your focus unless you have a great memory
Which is why I despise the current era of nitwits who denigrate our elders and ancestors and think anything before 2005 is so barbaric and backwards it shouldn't exist.
Very much depends on the person.
I wonder what the minimum integration error was on the best gyroscope based inertial guidance system. Was it better or worse than the MEMS accelerometers in smartphones?
Way back when, I worked on a stellar navigation system that had a CEP of 6 feet/hr. If I remember correctly, after 8 hours of flight, the largest error was ~20 feet.
I'm pretty sure that the best mems would fall short of what a real gyroscope can do for long term accuracy. Mems is just a couple accelerometers. Gyros lock the ring orientation to a reference.
Though mems can't get their rings stuck so that's a plus...
Navication gyros also get fed data from other systems to update them.
That said, with how accurately you can measure with ring laser gyros, you can now go hours without feeding corrections to an INS
@@joshuacheung6518 "Locking" vs differential measurements is a pretty meaningless difference when your lock drifts more then your integrated differential signal.
Nothing beats a good laser though, and those are also differential measurements.
Great presentation! I completely agree that our forefathers were amazing in what they accomplished! “Raw talent and shear force of will”! Very well said! Love it!
As a pilot i have been fascinated by those things since day 1! Beautiful stuff.
Thank you! :)
Idk why my eyes are wet 😭. You will have to be an engineer to understand how FUCKIN difficult it is to come up with a design like this, that too in an era without CAD and calculators. Just, all I can say is I am touching the feet of those legends.
Thank you for sharing this momentum with us!
The fact those connections go thru multiple spinning points is insane, the quality of connections must be unbelievable
That’s very relaxing to watch
Space Engineers is what first taught me of this. A device that can spin you and stop your spinning without gravity in a vaccuum.
It's been implemented in so many vehicle building games since then
You could never add up all the lives this device has saved. How important it's been for aviation and in turn how aviation created the modern world.
I apreciate the smoothness
