On The Shoulders Of Giants  

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. :-)

How tf do you get a jet gyro???

I just wish less technicians served the spaghetti Monster 😂

Well said!

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 retired recently and I worked in a refinery doing steam turbines and compressors and it is still pretty much the same old stuff, 0-25mm micrometers and DTI .Lots and lots of tiny measurements and clearances

Where can one find those?

Lol research engineer?

Makes it all the more frustrating when current day NASA thinks they know better than all those amazing engineers back then

As impressive as it is not art today people really call anything art if anything can be art, then what is art? I totally reject the notion

​@@darkplasmo7921that's fine! Art is what you make it.

Never read a book on Dadism eh?

@darkplasmo7921 this is art to me because of the meticulous way in which it was assembled. I see other hardware, especially some mass-produced by overseas factories, and would not say the same thing in those cases.

@@Physicsduck i am aware, i just think they are absolutely wrong the avant-garde movement has destroyed the fundamentals of art itself and alt how some involved in the movement have made interesting pieces it is, it was and is nothing more than a gimmick it was a rejection of order, but all it did was create a new flawed order I could write 10 pages on the topic, I know many artists and gallerists and discusses the topic many times I own a painting from Joan Miró I do consider many things art, just not an object created for a practical reason mass-produced and created in collaboration with many people.

Sounds like interesting game of battle tops.

Same here, ex Greenie/Avionics Tech on helicopters in the Army. I never get bored of Gyros.

Thank you sir you where more informative than the video creator

I want to quote this. Thank you

Which is great until they get a little too artistic and less mathematical 😂

Hardly.

As a mechanical engineer, I approve this statement

Some engineers are. Not all of them, unfortunately.

​​​@@porcupinepunch6893 people think that everyone today is stupid because they see stupidity all over the internet, the cause is "brain rot" from social media. I personally disagree, I think there were always stupid people and crazies, we just put them in insane asylums in the past so you didn't see them. Now we put them in Twitter and also journalism for the whole world to see, and it's a small minority of loud people.

Same here!

It's one of mine too.

I’m one of those who gained an interest in electrical engineering from always dismantling my electronic toys when I was 6

Get the shirts! It's how I support making these videos. :) bigbeaverenergy.com/collections/all

One used to find a full 3D versions at old surplus electronic shops. I used to have one. It would be very difficult to power up and process the signals but worth it if you have the skills.

Look up ones for missiles! They look just downright like something your steal from an alien ship. Like a fusion core. Even the old ones look wild. Also seekers look really cool as well. Actually just search on RU-vid of missiles being broken down from the cold war. Absolutely works of art. No wonder why they are expensive. I bet they are way more complex mechanically speaking then today. (Although in reality aren't. Just that circuit boards don't look as amazing since you know... Have to use a microscope to see things on the boards.)

lol! your #D printed version is nothing like this gadget. The tolerances in machining this are unobtainable by the 3D process. Like trying to make a V8 motor by chipping flint.

​@@user-cr5yy4te3i you sound like you think people really expect plastic model airplanes to fly

@@user-cr5yy4te3i Yes but you see, a 3D printed representation doesn't leave me in debt to acquire. Might not be JUST as good, but probably the closest most people are getting to one for a long time.

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!

Quick question, does those gyros adjust to earth curvature as the plane flies?

​@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.

i am terrified to ever touch the components of a plane from a repair standpoint. like that shit is eldritch to me

​The fact that he had to ask that means he's already confused.

stop the cap

Brilliant people on another way of thinking. 😊

Well these are from before then sooo not so elite, but still decent by todays standards

Aah the chair force. 😊

Good stuff

Thank you for that.

Miss Vito could have told him. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-LFdpIM5k_Sk.htmlsi=hbkpQWBTh-w0Hop2

Gold

Mona Lisa Vito would take exception to that, I believe.

The guys who have to fix it know how it works. We also are often tasked with finding fixes for engineerings mistakes.

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.

Thanks . This guy didn’t even attempt to explain what it is for those who don’t know

​@@WhuppusDingusHe probably assumed people who are watching his channel at least know what gyroscope is if not how it works.

​@@Physicsduck How old is this gyroscope ???

@@jangounchained5279really, some background info would’ve gone a long way

Wet beaver 🦫 bruh I do that too

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.

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

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.

​@@Kandrallayup

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.

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

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

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!

Thank you! I really hope to find someone who can help me get this working as a demonstration piece. :)

​@@PhysicsduckCrazy thinking this same technology was used for the V1 buzz bomb. It is a complicated and precise work of art.

The shirt is a whole in-joke for people in the power industry. bigbeaverenergy.com/collections/all You can get the story behind it here! ru-vid.com_Pc7jpDdD84?feature=share

I'm sincerely thankful you enjoyed it :)

Work on some of today's vehicles, you'll be thinking of discussions you would have with the engineer's who designed it.

Stanley Kubrick

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.

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.

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.

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.

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.

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.

Ezekiel?

Yes

With Bill Lear

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.

Thank you! :)
