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")

It was designed a long time ago and we've mindlessly copied it ever since.

exactly. the masses are naive to their own detriment.

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.

That's crazy! Nice work on the original design! -Steven

Better read the book itself.

lol

it would be a nice laser cutter project

either or!

oooh black walnut is nice

They are pretty cool thb, one of my favorite purchases

@@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!!!

My first sentence is already wrong lol... Shows how much I'm struggling

Nope. It is because the gear "escapes" the lever only to be caught again at the bottom.

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.

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.

It’s based on lies of history , no facts at all

Its a belt for a 3D printer! I got it off Amazon -Steven

@@3DPrinterAcademy awesome! Thank you so much :)

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.

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.

I so agree, though I've come across some far more excruciating cases on KZfaq. 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.

Yep, resetting the clock. Just lift the weight up and the weight on the other end of the chain will pull the slack.

Because it’s weights don’t directly turn the escapement wheel, it turns it through a gear set

But thats exactly how pendulum clocks work

@@djthdinsessions that's a gear. That's not a clock.

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

@@djthdinsessions I still would not call it a clock also Sailors didn't use a gravity gear because they didn't work at seas due to waves. John Harrison had to invent a balancing gear specifically because a gravity gear didn't work at sea. This whole video is a joke and ignorant.
