Original clock design by Dynasus November 12, 2015 CC Atribution

Happy printing,

A very smart design that most people probably never even knew existed
It was designed a long time ago and we've mindlessly copied it ever since.
exactly. the masses are naive to their own detriment.
So basically all they did later on was add a spring that would to create the potential energy. Winding it up adds tension and then you release the tension the same way you did the belt with weights and now it can go possibly longer and in a much smaller space. It's really fun to pick a apart simple machines like this I would love to see more videos just breaking down these simple machines and even seeing some small applications for the fun of it
Tick tock
Basically
It needs a pendulum too, so on something like a wrist watch, the pendulum is circular.
Yes but the key was designing springs that provides a constant force. Normal, everyday springs don't do that. But of you make the spring much much longer than it's intended range of motion, you can get * close * to constant force. That's why spring powered watches have such a long, winding, spring coil inside of them.
@@darrennew8211 well, "pendulums" are gravity-based. The "circular pendulum" you mentioned is a little wheel that oscillates based on springs instead of gravity. (and that's a different spring than the power spring I mentioned in my other reply)
(I know you may have known that, I just think it's misleading to others to call it a "circular pendulum")
Actually, the timepieces used by sailors were spring-powered, not gravity powered. This prevents them from losing time as gravitational acceleration changes, for example during rough seas. Accurate marine chronometers were expensive though, so up until the last couple centuries sailors mostly determined the time by the lunar distances method. Nautical almanacs are filled with tables of the moon's position in the sky, calculated years in advance, and by consulting the almanac and measuring the distance between the moon and another celestial object, the absolute time can be accurately determined. This is then compared with the observed local time to determine longitude.
How accurate was this?
@@ewthmatth Typically the error was +/- 1 minute, which corresponds to an error of about one-quarter of a degree of longitude, or about 15 nautical miles (28 km) at the equator. (Source: Wikipedia.) Skilled lunarians could reduce the error down a little bit lower than that.
Yeah, I distinctly remember that sailors tried using gravity powered escapements to determine their longitude, but it never worked because the rocking boat would throw the pendulum around and screw up the timekeeping. It wasn't until decades (maybe even centuries) later, when spring-powered escapements were invented, that sailors could use clocks for navigation.
@areadenial2343 is right. marine chronometers weren't sufficiently accurate until the late 1700s, and weren't in common use until the 1800s. also the pendulum clock was invented by christiaan huygens inspired by galileo's discovery that the period of a pendulum was constant.
Nice to see that my original design has evolved!
Got pretty surprised when TH-cam recommended it to me all of a sudden.
Love the idea with the timing belt. Also, I think you made a very interesting video. Keep it up!
That's crazy! Nice work on the original design! -Steven
This is not criticism. In this video, you had a perfect opportunity to also show how to slow or speed up the escapement with the length of the pendulum.
Thank you very much for your explanation about escapement!
This is what I always have been wondering
Thank you
lovely video
Escapements are cool, many other designs have evolved like the swiss lever or coaxial for mechanical wristwatches
Nah the sailor clock was invented by John Harrison with the h1 clock not Galileo this is well documented and undisputed in fact as a normal escapement as shown in the video was inaccurate at sea.
The grasshopper escapement and a swinging balance allowed accurate timekeeping at sea invented by john Harrison. He saw clocks differently as a synchronised ecosystem. Harrisons h1 clock design made the UK forces superior with accurate timekeeping no other country had and become the leading navy with the first clocks that worked at sea. Escapement gears like the one in this video didn't work at sea, it was the invention of the grasshopper escapement and a balanced swing which was unaffected by the motion of sea.
thank you for explaining how the clocks were used to determine sailor's position on earth. I would've entered another rabbit hole just to find out about it
More gravity powered devices, cool
Thanks a lot! I like this mechanics )
This would be good to use in clocks.
lol

@@3DPrinterAcademy This Cube Cured my Mortality
Reviewed in the United States on November 9, 2019
All the people here who bought this wireless tungsten cube to admire its surreal heft have precisely the wrong mindset. I, in my exalted wisdom and unbridled ambition, bought this cube to become fully accustomed to the intensity of its density, to make its weight bearable and in fact normal to me, so that all the world around me may fade into a fluffy arena of gravitational inconsequence. And it has worked, to profound success. I have carried the tungsten with me, have grown attached to the downward pull of its small form, its desire to be one with the floor. This force has become so normal to me that lifting any other object now feels like lifting cotton candy, or a fluffy pillow. Big burly manly men who pump iron now seem to me as little children who raise mere aluminum.
I can hardly remember the days before I became a man of tungsten. How distant those days seem now, how burdened by the apparent heaviness of everyday objects. I laugh at the philistines who still operate in a world devoid of tungsten, their shoulders thin and unempowered by the experience of bearing tungsten. Ha, what fools, blissful in their ignorance, anesthetized by their lack of meaningful struggle, devoid of passion.
Nietzsche once said that a man who has a why can bear almost any how. But a man who has a tungsten cube can bear any object less dense, and all this talk of why and how becomes unnecessary.
Schopenhauer once said that every man takes the limits of his own field of vision for the limits of the world. Tungsten expands the limits of a man’s field of vision by showing him an example of increased density, in comparison to which the everyday objects to which he was formerly accustomed gain a light and airy quality. Who can lament the tragedy of life, when surrounded by such lightweight objects? Who can cry in a world of styrofoam and cushions?
Have you yet understood? This is no ordinary metal. In this metal is the alchemical potential to transform your world, by transforming your expectations. Those who have not yet held the cube in their hands and mouths will not understand, for they still live in a world of normal density, like Plato’s cave dwellers. Those who have opened their mind to the density of tungsten will shift their expectations of weight and density accordingly.
To give this cube a rating of anything less than five stars would be to condemn life itself. Who am I, as a mere mortal, to judge the most compact of all affordable materials? No. I say gratefully to whichever grand being may have created this universe: good job on the tungsten. It sure is dense.
I sit here with my tungsten cube, transcendent above death itself. For insofar as this tungsten cube will last forever, I am in the presence of immortality.
Not to be a stickler, but I believe that the tungsten block that you’re referring to is 2.2 pounds, not 2.2 kg, which would then equate to 1 kilogram!!! I know it’s not here nor there, I knew what you meant and I do apologize in advance. Have a great day!!!
this was amazing
thank you....i did not understand how the pendulum was kept going....now i do.
Accurate timekeeping was also essential for the blossoming railway industries, allowing more throughput of goods safely
Nice very smart ⏰ 👍
This is absolutely genius.
Saw this also interesting movie longitude
Better read the book itself.
You put the potential force the wrong way. Its rotation should be reversed to prevent the cogs from stopping the pendulum's inertia so it runs for longer. It also allows the small flaps that are angled are able to get the force required to keep the pendulum swinging. I'm surprised only a few have realized.
Good video
Subtle tungsten cube flex
this man became my history teacher for a minute
I understand this because the pull from the weight is constant. But I don't understand in wrist watches where the main spring provides the energy because it seems to me that when the spring is fully coiled, the energy would be greater than when it's nearly fully uncoiled.
My first sentence is already wrong lol... Shows how much I'm struggling
What is counterintuitive about this is how the speed of energy release is constant. More so with a wind up spring that gets weaker the less it's is wind up
Exelent video 👍 how many od theath must have the wheel of escapement ??? 🤔
This seems like a very decent "experienced beginner" woodworking project. Intricate pieces, but not too much. Lots of potential room for carvings as well. I think I might work on a design, see where it leads me. I think I actually have the wood already too, some nice Black Walnut. Thanks for the idea. ✌️👌
Liked and subbed.
it would be a nice laser cutter project
either or!
oooh black walnut is nice
Grate 👍
I can't believe I never knew about this
Cool !!!! But I wonder how the people from the poles would know their longitude without a sunset for half year
The most important invention most people don't know about
Something I long wanted to know and beautifully explained. One reason for my curiosity was the word "escapement" itself. Is this due to the forerunners of mechanical clocks being water clocks, in which a simple hole at the bottom of a vase regulates the speed of the escaping water just as the speed of the falling weight, and its "escaping" gravitational energy, is in the mechanical clock?
A word which goes with "escapement" is "catchment". Maybe there was a catchment vase for the escaping water.
Nope. It is because the gear "escapes" the lever only to be caught again at the bottom.
this is underrated and needs more views
It’s based on lies of history , no facts at all
Years ago I create a "gravitational fan" with an escapement and a gearbox, could you replicate it with a 3d printer? It would be awsome to see it in this channel
Very cool. Its possible to make a loop and do a working clock?
No loop. A pendulum clock needs reset every time the weight gets close to the end of its chain; just lift it up and the counterweight on the other side will drop, pulling the slack. Now the clock can continue running.
So what if you build a massive clock, could it provide a suitable amount of energy?
I mean, it's pretty darn clean right?
It doesn't make any energy, it stores energy (your energy when you reset the weight) and releases most of it at a controlled rate, the rest is lost through friction. In this particular design it seems to lose all of the energy as no work is actually performed. The usual way to store energy for later release in a productive manner would be to pump water up into a large reservoir and release it through a turbine electric generator, better of course if you can command the rain to fill the reservoir.
Can you do one that has a spring you wind up? It could be built into the center of the wheel. That would give it a longer potential run time. Nothing like a complicated clock but something to show how a spring in a clock works with an escapement wheel.
springs are finicky and dangerous, not for 3D printed cases.
@@h7opolo you could try putting a small metal ring in the middle to mitigate the plastic fatigue.
@@frankdelucey2137 oh, but of course.
@@h7opoloSo you don't trust 3d printed with metal inlays?
@@frankdelucey2137 my reply to your reply should mean to excuse my original reply.
Awesome video, but ... This is an escapement, I wanted the whole clock 😏
"gravitational potential energy, now this may sound complicated."
It really doesn't. I mean if you know how gravity works you can pretty much figure it out
That is continous Motio
What he is not showing is the restoration happens exactly at the the point where the pendulum kinetic energy is maximum so that the change in velocity is minimized. It’s lot more complicated and cooler than it’s shown here.
Inventor of the pendulum clock is Christiaan Huygens.
What can I use as a tread/ belt? Please help!!!
Hey! I’m building something similar myself and was wondering where you got the band?
Its a belt for a 3D printer! I got it off Amazon -Steven
@@3DPrinterAcademy awesome! Thank you so much :)
Nice video, I but Galileo did not invent escape mechanisms, and far as I know never really did anything with clock mechanics. TheTelescope was something in which he contributed greatly to its improvement and usage. Also sailors didn't use escapement clocks because they don't do well on a rolling pitching ocean
Okay, I admit this was cool, but can I also get the video on Archaic Sea Navigation? Heh.
ok.. Here’s a question. It’s a thing I need. I have a feeling it’s possible.. probably quite simple when fully refined and would potentially be very comercial if produced. A water powered irrigation timer.
I have a stream that enters our land from above. I have a simple pipe sitting the stream tip the hill which gives me free water at great pressure to irrigate all my veg.
I want to automate the timings of the sprinklers for many obvious reasons. I thought this would be simple but it seems not.. The irrigation timers I can find on the market all seem complicated and crazy expensive.. I feel sure that I should be able to use the water pressure to power a kind of clock mechanism which could turn a switch on and off at set intervals.. Does that sound doable to anybody.
Its a fairly common situation.. the only variation is that most people are using municipal water supplies but the pressure is equivalent. I’m confident if a timer could be made that used only the water pressure, was 3D printed so therefore easily scalable, had no electronics so much less to go wrong it would be a very viable commercial product.. I’ve had a few designs but nothing is slotting fully into place yet.. any thoughts anybody..?
There's ramps here, how to the ramps work? What angles do to they need to be?
I am designing it myself
This is basically what we in algodoo call for a “normal” clocks inside
bro
pls add background music that is way louder than the one in this video so that the loudness of your voice can be compensated.
1:49 I notice the 2.2kg mass, a perfect number. If only that were our unit, where 2.2kg could be one unit.
You mean where 2.2 of your unit could be 1kg?
@@quattrocity9620well, we already have that unit, as you know, the pound. My comment is that the content creator used 2.2kg which is 4.85lbs. it just seemed silly to me, so I wrote my comment.
hard to believe that this video, and the "tourbillon" video came from the same time period. the tourbillon video has a much better audio job done to it.
I want a version that can fully recharge a laptop within 8 hours, lol.
Is that why some coordinates are in minutes?
it would be helpful when there is no music when you're explaining stuff
I so agree, though I've come across some far more excruciating cases on TH-cam. Don't producers realize intrusive background music is going to spoil, not enhance, an interesting verbal account? Also I resent the implication that I need "exciting" music to be excited about the subject matter.
I like it but this would require a full time attendant to reset the weight every couple of minutes. Can one be made to last 24 hours without attention?
opportunity missed: the pendulum length dictates the period of time. the longer the pendulum the longer it takes for the escapement to complete one cycle.
Клас 😊
The trick is to get the weight back to the top.
Yep, resetting the clock. Just lift the weight up and the weight on the other end of the chain will pull the slack.
The damn wheel is spinning THE WRONG WAY 😂
Losing like 75% efficiency lol
My mother was a horologist
Sailors did not use pendulums, or if they did their clocks were extremely inaccurate.
Why hasn’t anyone used this technology to store solar energy to be released at night as an alternative to batteries?
You make giant concrete weights that are lifted up using solar power and a gearing mechanism and then at night allow the weights to drop the drive a Generator.

I would not call it archaic, I would call this highly ingenious since they were able to find roughly where they were on the globe in the middle of the ocean well before GPS.
(Also disproves flat earth theory. though this has been done many times before :p)
hey, Galileo is actually the father of science and travelled back in 1634 after stealing the pendulum swing mechanisim from the Pharaohs
Tik tik tik tik tik tik tik tik tik
Oo
"Pendulum clocks immediately became the best timekeepers for use on land. But several sea trials demonstrated to Huygens that the pendulum clock would never work accurately on a heaving ship's deck." Nice try, though....
Nice video but the music is too loud and unnecessary.
failed to explain how to make it run longer
700th like
Hello… Galileo has nothing to do with the invention of the pendulum clock. He only described and proved that swinging time has nothing to do with the weight of the pendulum but it’s the length that got the most effect…. On dec 25 1656 Christiaan Huygens made the first working clock due to this principle and become the official inventor of the pendulum clock. Galileo died almost 9 years earlier on jan 8 1642.
Wowsers. I got a pronoun advert before this interesting video on physics.
The message must be proliferated. Long live the Algorithm. Glory to the Alphabet.
music too loud
big ben uses pennies or pence
Yah. But how does a grandfather clock not need to be reset every hour???
Because it’s weights don’t directly turn the escapement wheel, it turns it through a gear set
i cant hear you due to the music
quick update for older people: We learn abt gpe & tension potential energy in 6th grade now. We also learn stuff from the internet.
use it to recharge the batteries of electric cars
Do more research, you're mixing up events:
1) Sailors were unable to use pendulum clocks at sea (for what are hopefully obvious reasons), thus for centuries they were unable to reliable know their longitudinal coordinates. It wasn't until reliable portable spring-powered cocks were invented that sailors could bring a clock out to sea that allowed them to determine their approximate longitudinal coordinates.
2) Common practice wasn't to use sunset/sunrise times, because again (for hopefully obvious reasons) that's not a universal measurement. Instead what was compared was midday. I.E. set your fancy new spring-powered clock to noon when the sun is highest in the sky the day before leaving port in London etc. Days or weeks later, somewhere in the Atlantic Ocean, you compare midday (the sun's highest point in the sky) to your clock and there you go, your approximate longitude: if it's local noon, but your clock set to London says 10:00AM, you're approximately 30 degrees Longitude west of London.
Dude, calm down with the music. Hard to hear.
"this allows for extra friction between the belt and the wheel" - absolutely lost me there. needs a much better explanation. whatever this means is just glossed over.
Maybe that's just but these feel... Kind of over explained.
Why first you spend over 25% of time on "something else" and only after You shift focus on issue in the title. Great explanation but would be nice to do opposite and "respect time" of those who were here only for "escapement mechanisms" ?? :)
Just stop the background music.
Finding longitude isnt complicated you just made it sound that way for your video. Longitude=timezones. There done.
Edit:
People are smart if you treat them that way and your video discourages people from doing that.
Kicking people down for your own gain, Shame on you
And boom the earth is flat
Annoying music!
But is this clock really usefull? I mean, it only have energy for at most 1 minute, and if you need to be constantly recharging it, even if you are perfectly aware of this all the time which would be insane, you will be at least 1 hour off after a day passes. And how even displays time? If this was a real clock I think you are forgething a hell of a lot of parts.
This video explains nothing
That's not a clock
But thats exactly how pendulum clocks work

@@royaldecreeforthechurchofm8409 The title never says its a clock, the title says thats how do gravity powered clocks work, and that's exactly how
