This 3D-printed reconstruction of the Galileo pendulum was developed by Luke Stern for the Laboratory School for Advanced Manufacturing (http://www.nsf.gov/news/news_summ.jsp?cntn_id=129472).
This is my new Lego Pendulum Clock that's fully functional. It has both minute and hour hand which can be adjusted to set the time right. The pendulum is set to swing once per second. It can be winded up again with either the key or a motor. I'm working on making a auto-winding mech so that you wont need to wind it up yourself. The weight weighs about 2 kg. I've also build a differential so that the pendulum can swing even when winding up the weight.

This lego clock is a working model with pendulum and escapement. It has seconds hand, hour hand and minutes hand. There is no batteries and you have to wind it up every four minutes, so it is not very efficient. INSTRUCTIONS AVAILABLE:

This is a tutorial showing you how to make a pendulum clock. We keep it simple and it doesn't keep actual time but it does show phases of the moon as it runs. Fun project that uses foam board. And you learn about how a pendulum clock works and why it makes that tick-tock sound.
With this project you actually make a simple pendulum clock without having to make all those gears. This one uses an escapement and a single gear to progress the phases of the moon.
The template for this project with all the parts is on my website right here:

About escapements and pendulum clocks.
Galileo invented the first pendulum clock in 1642 but didn't build one. Christiian Huygens built the first working pendulum clock in 1656. A wide variety of escapements have been invented and designed. The type we use in this tutorial is called a single pin escapement. It is a very simple configuration and it was invented by Charles MacDowell in 1851.

A homemade mechanical rolling ball clock (english, deutsche Version: http://youtu.be/wJK0AjOHbzk)
The clock runs for 12 hours, driven by a weight of 2.5 kg sinking approx. 1 meter during that time..Every minute a marble is lifted up and goes down a marble run with three flipping traps that count marbles for minutes, five-minute-steps and hours.
The timekeeping element is a second-pendulum with a pinwheel escapement.
The clock achieves a drift of less than 1 second per day.
I have to admit that this is based on a measurement over 24 hours only, so it does not include large temperature variations. Nonetheless, I did not expect that high accurracy. But keep in mind that a pinwheel escapement is among the most precise.

My own unique design Pendulum Driven Clock which is driven by the weight of the water landing in the 'cross' tube of the pendulum assembly which is divided by a baffle. As the pendulum swings the water is forced to flow into one side then the other... the resulting movement then powers the clock by means of the escapement (ratchet) wheel.
All white parts are machined from acetal, the gear teeth are hand cut on my band saw and 'broached' where needed with pillar drill (drill press).
All shiny parts are stainless steel, welded with my 'RTECH 200' tig.
The Clock 'ticks' at 46 beats per minute and therefore the escapement wheel has 46 teeth... from there on it is simple to gear the minutes and hours. Apart from the obvious water power (small pond pump in base), the other unique thing is the drive from the escapement (Not a true escapement as it only drives the clock and isn't regulating the drive from the pendulum in any way) to the minute (60 tooth) wheel is by effectively a one tooth gear, having a single peg which only engages once per revolution and does away with one complete 60 to 1 gear train.
Fine adjustment is via a bob weight at the bottom of the pendulum and works opposite to convention, i.e. up is slower and down is faster (due to the amount of time the water has to escape the tube)
This is my first attempt at building a clock and took me 10 days straight!

A pendulum clock is a clock that uses a pendulum, a swinging weight, as its timekeeping element. The advantage of a pendulum for timekeeping is that it is a harmonic oscillator; it swings back and forth in a precise time interval dependent on its length, and resists swinging at other rates. From its invention in 1656 by Christiaan Huygens until the 1930s, the pendulum clock was the world's most precise timekeeper, accounting for its widespread use. Pendulum clocks must be stationary to operate; any motion or accelerations will affect the motion of the pendulum, causing inaccuracies, so other mechanisms must be used in portable timepieces. They are now kept mostly for their decorative and antique value.
The pendulum clock was invented in 1656 by Dutch scientist Christiaan Huygens, and patented the following year. Huygens contracted the construction of his clock designs to clockmaker Salomon Coster, who actually built the clock. Huygens was inspired by investigations of pendulums by Galileo Galilei beginning around 1602. Galileo discovered the key property that makes pendulums useful timekeepers: isochronism, which means that the period of swing of a pendulum is approximately the same for different sized swings. Galileo had the idea for a pendulum clock in 1637, which was partly constructed by his son in 1649, but neither lived to finish it. The introduction of the pendulum, the first harmonic oscillator used in timekeeping, increased the accuracy of clocks enormously, from about 15 minutes per day to 15 seconds per day leading to their rapid spread as existing 'verge and foliot' clocks were retrofitted with pendulums.

HOW A PENDULUM WALL CLOCK WORKS
Pendulum clocks have been used to keep time since 1656. Pendulum clocks were the first clocks having sort of accuracy. In an old Pendulum CLOCK several different parts are important: There is the face of the clock, with its hour and minute hand. A keyhole used to wind a spring inside the clock. And, of course, there is the pendulum itself. In most wall clocks that use a pendulum, the pendulum swings once per second. In small cuckoo clocks the pendulum might swing twice a second. In large grandfather clocks, the pendulum swings once every two seconds. -

This is a tutorial showing you how to make a pendulum clock. We keep it simple and it doesn't keep actual time but it does show phases of the moon as it runs. Fun project that uses foam board. And you learn about how a pendulum clock works and why it makes that tick-tock sound.
With this project you actually make a simple pendulum clock without having to make all those gears. This one uses an escapement and a single gear to progress the phases of the moon.
The template for this project with all the parts is on my website right here:

About escapements and pendulum clocks.
Galileo invented the first pendulum clock in 1642 but didn't build one. Christiian Huygens built the first working pendulum clock in 1656. A wide variety of escapements have been invented and designed. The type we use in this tutorial is called a single pin escapement. It is a very simple configuration and it was invented by Charles MacDowell in 1851.

A homemade mechanical rolling ball clock (english, deutsche Version: http://youtu.be/wJK0AjOHbzk)
The clock runs for 12 hours, driven by a weight of 2.5 kg sinking approx. 1 meter during that time..Every minute a marble is lifted up and goes down a marble run with three flipping traps that count marbles for minutes, five-minute-steps and hours.
The timekeeping element is a second-pendulum with a pinwheel escapement.
The clock achieves a drift of less than 1 second per day.
I have to admit that this is based on a measurement over 24 hours only, so it does not include large temperature variations. Nonetheless, I did not expect that high accurracy. But keep in mind that a pinwheel escapement is among the most precise.

My own unique design Pendulum Driven Clock which is driven by the weight of the water landing in the 'cross' tube of the pendulum assembly which is divided by a baffle. As the pendulum swings the water is forced to flow into one side then the other... the resulting movement then powers the clock by means of the escapement (ratchet) wheel.
All white parts are machined from acetal, the gear teeth are hand cut on my band saw and 'broached' where needed with pillar drill (drill press).
All shiny parts are stainless steel, welded with my 'RTECH 200' tig.
The Clock 'ticks' at 46 beats per minute and therefore the escapement wheel has 46 teeth... from there on it is simple to gear the minutes and hours. Apart from the obvious water power (small pond pump in base), the other unique thing is the drive from the escapement (Not a true escapement as it only drives the clock and isn't regulating the drive from the pendulum in any way) to the minute (60 tooth) wheel is by effectively a one tooth gear, having a single peg which only engages once per revolution and does away with one complete 60 to 1 gear train.
Fine adjustment is via a bob weight at the bottom of the pendulum and works opposite to convention, i.e. up is slower and down is faster (due to the amount of time the water has to escape the tube)
This is my first attempt at building a clock and took me 10 days straight!

Pendulum clocks have been used to keep time since 1656. Pendulum clocks were the first clocks having sort of accuracy.
In an old Pendulum CLOCK several different parts are important:
There is the face of the clock, with its hour and minute hand.
A keyhole used to wind a spring inside the clock.
And, of course, there is the pendulum itself.
In most wall clocks that use a pendulum, the pendulum swings once per second. In small cuckoo clocks the pendulum might swing twice a second. In large grandfather clocks, the pendulum swings once every two seconds.
