WINDSTORM DRAGON

Windstorm Dragon – wooden mechanical 3D puzzle from Ugears

Welcome to the dwelling of a wise and cunning beast guarding countless treasures he will only reveal to the one bold enough to face his mechanical magic! Behold – the magnificent Windstorm Dragon of the Ugears’ automatons collection is here to challenge your wits and skills in your next mechanical models adventure.

The Windstorm Dragon is a classic mythical reptilian, the embodiment of ancient might and power, presented in wood and animated by the wizardry of Ugears engineers.

Wooden DIY 3D puzzle Windstorm Dragon has an open-style design that allows you to see its mechanical heart – rubber-band motor – beating. The model has a winding key in the frontal part of its chest. To wind it up, hold the dragon by its body and rotate the key clockwise. Release the motor by pulling the start lever. This is when the magic begins: the arms, legs and even the whole body of the Dragon will start to move. And of course, the amazing pair of strong and beautiful wings will be set in motion. This is your Ugears Dragon’s very special feature: the bones of the wings are made of wood, but the rest is beautifully designed feathery paper cutouts. Softer and flexible material makes the flight look very realistic and leaves room for your own ideas.

The model can be set on a special support or hung on twine. It will look equally fascinating with its laser engraved scales and spiky tail. It’s a perfect gift for your family and friends.

Like all Ugears models, this automaton is made of high-grade wooden materials and comes with everything you need in the box. Solve the mechanical mystery of an ancient beast and become a Dragon Master with Windstorm Dragon Ugears model kit!

ARITHMETIC SET STEM LAB

Educational 3D puzzle Arithmetic kit by Ugears STEM Lab. Discover in AR

Assemble the Arithmetic Kit and discover how the Mechanical Addiator and Mechanical Multiplier work.

- The model kit comes with a QR-code to the study guide about the mechanisms, the principal of their working, the main characteristics, formulas. It also includes interesting assignments.
- Dive into augmented reality and look at how Mechanical Addiator and Mechanical Multiplier work. Interact with the models via a special AR application from Ugears.

UGEARS' Arithmetic Kit, part of UGEARS' STEM Lab collection, consists of two ready-to-assemble models: A Mechanical Addiator and a Mechanical Multiplier.
Find out how the Mechanical Addiator and Mechanical Multiplier work

The Mechanical Addiator is a compact arithmetic machine (or adding machine) that works by moving gear racks, using a stylus included in the kit. By moving the sliding racks, marked with arrows and numbers from 0 to 9, you can add and subtract numbers.

The Mechanical Multiplier is a flat hinge mechanism that accomplishes binary operations on numbers. By moving the dual slider, you can multiply and square numbers from 1 to 12, making the multiplication table fun.
Who invented the Mechanical Addiator and Mechanical Multiplier, and when?

The UGEARS Mechanical Addiator is a DIY wooden model kit based on an addiator that was invented by a St. Petersburg music teacher, Heinrich Kummer, in 1846. Its simple design and compact size made it a popular mathematical tool in its time. Today this simple, fun mechanism is part of UGEARS' outstanding STEM Lab collection.

The UGEARS Mechanical Multiplier is a fun wooden 3D puzzle based on a children's toy, “Consul the Educated Monkey,” invented in 1915 by William Henry Robertson, an American high school math teacher. Robertson applied for a patent for a toy that ingeniously uses a hinged mechanism to perform simple multiplication, designed "to stimulate children's interest in the study of numbers.”
Uses for The Mechanical Addiator and Mechanical Multiplier

The Mechanical Addiator is used to add and subtract numbers. To do this, the user enters a number value using the stylus, then uses the stylus to enter a second number. The device then shows the result of the desired mathematical operation, according to where the second number was entered (top row for addition, bottom row for subtraction). But the Addiator is not limited to addition and subtraction—you can also use it to multiply and divide.

The Mechanical Multiplier is a simple and interesting way to learn the “unloved” multiplication tables from 1 to 12, and to understand the simple principle of hinge-lever mechanisms. When the two sliders are moved to various numbers, you will see their product displayed in the window above.
Components of the Mechanical Addiator and Mechanical Multiplier, and how they work

The Mechanical Addiator consists of a housing in which four rails or racks are set, with printed values on them. A stylus is used to input values. Numbers are entered from cam slots, and the results are displayed in four center windows. Before starting an addition/subtraction operation using the stylus, the racks should be set so that all windows display "0". The value of the number on which the operation is performed is first entered using the top row of slots; the top slots are then used to add a second number, while the bottom ones are used for subtraction.

The Mechanical Multiplier consists of two sliders which move along a number line (1-12), and a lever system which transfers the movement of the sliders to a “Results” window, which moves along a value field. As you move the two sliders between different number values, the product of their multiplication will appear in the “Results” window. In order to multiply a number by itself (to square it), the right slider should be moved to the extreme right position and fixed at the "X²" symbol.

UG70153 Ugears Model TACHOMETER STEM LAB

TACHOMETER STEM LAB

Educational 3D puzzle Tachometer by Ugears STEM Lab. Discover in AR!

Assemble the Tachometer and discover how it works.

- The model kit comes with a QR-code to the study guide about the mechanism, the principal of its working, the main characteristics, formulas. It also includes interesting assignments.
- Dive into augmented reality and look at how the Tachometer works. Interact with the model via a special AR application from Ugears.

Learn how the Tachometer works

A tachometer is a device designed to measure the rotational speed of various parts in engines and other mechanisms. It calculates revolutions per minute (RPM). The tachometer also measures and monitors load limits, in order to decrease or increase RPM so that the engine or mechanism runs within its optimal parameters.
Who invented the Tachometer, and when?

The tachometer was invented by the German engineer Dietrich Uhlhorn in 1817. His invention was a special device that measured centrifugal force. From 1840 on, this device has been used in railway locomotives, and later in cars and all manner of vehicular transport.
Use

The tachometer is used in mechanisms where it is necessary to accurately track RPM to avoid the negative consequences of overloads. Savvy motorists use tachometers to know when to shift gears (in cars with manual transmissions) and to control the load on the engine, thereby increasing the operating life of their vehicles.
What the Tachometer consists of and how it works

The Tachometer 3D puzzle from UGEARS' STEM Lab collection is a fully operational DIY wooden model of a tachometer, ready for you to assemble. When the handle is rotated, movement is transmitted through a reducer, increasing the RPM and displacing twin weights in the centrifugal unit. The higher the RPM, the more centrifugal force separates the weights, shifting a movable axle with flywheel. A pointer mechanism (dial) is fixed to the axle; the more the axle shifts (higher RPM), the more the dial arrow deflects, indicating higher speed rotation.

What the Tachometer consists of and how it works
The Tachometer mechanism consists of:

- Handle
- Reducer
- Weights
- Axle
- Flywheel
- Dial

Connect the Tachometer to the Variator, creating a new mechanism

The Variator-Tachometer system demonstrates the direct relationship between the transmission ratio of a gearbox, and rotational speed.

When the handle of the Variator is rotated, the movement is transmitted through the reducer to the cone-shaped driving pulley. The rotation of the first cone is then transmitted through the belt to the other cone, which is the driven pulley. When the pedal attached to the housing is pressed, it shifts the fork holding the belt, thereby changing the rotational speed of the driven pulley. When the Tachometer is attached to the Variator, the changing rotational speed of the driven pulley of the Variator is transmitted to the Tachometer's reducer. This in turn will increase or decrease the centrifugal force on the weights, shifting the axle with flywheel. Shifting the axle deflects the indicator on the dial toward a higher or lower value. In this way, changes to the transmission ratio in the Variator will be seen to increase or decrease the RPM of the attached Tachometer.

UG70154 Ugears Model AERO CLOCK

AERO CLOCK

Aero Clock. Wall clock with pendulum – wooden mechanical 3D puzzle from UGEARS

The time has come! For years, we've been hearing the same question again and again from our loyal customers: "Can Ugears create a working clock model kit, one that actually keeps accurate time?" A working mechanical wooden clock has long been our #1 "most-requested" new design. Your dream has also been our dream, and our team of dedicated Ugears engineers and designers has been working hard to bring this shared dream into reality. Finally, the wait is over. Ugears is proud to present the Aero Clock, a fully-functioning DIY wall clock with pendulum.

The Aero Clock isn't just a 3D wooden mechanical model, or a pretty showpiece. The Ugears Clock is an actual working clock that you can build yourself, mount to a wall, wind up, then watch as the seconds, minutes, and hours tick by. The Aero Clock is an ingenious puzzle and DIY clock mechanism, unlike any other clock. It is a lovely piece of precise engineering that reveals the workings of a weighted pendulum clock to builders and viewers alike. Like all Ugears models, it also has that extra touch of whimsy, to captivate and charm our growing legion of fans.

This simple-yet-elegant Ugears clock is driven by the force of gravity pulling down a weighted bag (you can fill the bag with sand or salt). Raise the bag on its pulleys to wind the clock. As the weight slowly descends, it rotates a drive gear, which then rotates an escape wheel through a reducer. The clock features an adjustable weighted pendulum which interacts with the escape wheel through the steady tick-tock of the anchor mechanism. You can adjust the clock's ticking action to the second, by sliding the pendulum's top and bottom weights. The reducer also transmits rotation to an hour disc and a minute disc. One of the interesting features of our Aero Clock is that time is not read with rotating hands on a clock face, but rather a fixed pointer indicates time on the slowly-rotating, numbered hour and minute discs. Moreover, these discs rotate counterclockwise—did you know that before standardization, some clocks moved clockwise while others moved counterclockwise? In the role of "cuckoo” the Ugears Aero Clock features a model hot air balloon. The suspended balloon rapidly descends when the hour strikes, then slowly rises again over the course of the next hour.

The theme of the Aero Clock is early aeronautics. Take a trip back in time to the dawn of flight and the "balloonomania" that seized France and England in 1783 on the occasion of the first free aerial voyage in a balloon. This was followed two years later by the first aerial crossing of the English Channel by intrepid aeronauts Jean-Pierre Blanchard and John Jeffries. We love this wooden model clock's steampunk sensibility and spirit of adventure, and we think you will too! Imagine yourself a discoverer of new horizons and a conqueror of the four winds. The casing and intriguing wooden clock mechanism represent an air base located among the clouds, where zephyrs blow and filtered rays of sunlight dapple the machinery, while you, in the role of aeronaut, launch a new voyage of exploration on the hour.

The Ugears wooden model clock kit celebrates the role of clocks in exploration. Did you know the problem of calculating longitude, critical to accurate navigation at sea, was solved with a clock? The idea was proposed by Dutch mathematician Gemma Frisius in 1530, but it wasn't until the mid-18th century when English clockmaker John Harrison developed a series of shipboard clocks so precise (accurate to within a ? of a second per day) that ship captains could at last calculate their position at sea to within a few nautical miles. By knowing the exact time back in London (Greenwich Meridian Time, or GMT), and calculating the time at current position with celestial observation, navigators could calculate where they were on the earth's surface. Latitude had been solved by the Phoenicians as early as 600 B.C. with celestial reckoning—measuring the altitude of the sun at noon, or the angle made between the North Star (or other navigational stars) and the horizon. But the longitude problem would bedevil explorers for another 2,000 years. Harrison was eventually awarded the £20,000 first prize (roughly $1.5 million today) established in Parliament's Longitude Act of 1714, after demonstrating the accuracy of his masterful clocks at sea. Now you too can become a clockmaker, with the Ugears Aero Clock model kit!

Released at a moment when the world seems to have slowed down, the Ugears Aero Clock, a wooden wall clock with pendulum that you build yourself, is both timeful and timeless in its simple elegance. This beautiful and functional wooden wall clock model is for horologists, for hobbyists, for explorers, for creatives and romantics of every stripe, anyone who is ready for new challenges and ready to take risks. If you've ever gazed up at the sky and thought, "I want to be there!" or looked at a pendulum clock and wondered, "How does that work?" then the Ugears Aero Clock is for you.

As you build the Aero Clock, a wooden wall clock with pendulum, you will learn the basic principles behind clockworks, how the steadying influence of a swinging pendulum operates through a rocking anchor, locking and unlocking the gears on an escapement one second at a time, thereby regulating the (slow) descent of a weight as it drives both power gears and timekeeping gears.

The Ugears' Aero Clock with pendulum is a marvelous puzzle, and the perfect family project. When you work together to assemble this DIY wooden clock model kit, you will experience the satisfaction of building something together, and not just any model, but an actual functioning timepiece. Afterwards, you'll have a beautiful object for the home, something your family can enjoy together as time goes by.

The Ugears Aero Clock with pendulum is a new and exciting addition to the Ugears collection of fascinating mechanical models, 3D puzzles, game accessories, wooden puzzle boxes, children's toys and education STEM Lab model kits.
