The Butterfly is not a static stand model, but an animated kinetic sculpture. Each of its details designed to make sure it fits its own place and plays its own part in the workings of this outstanding mechanism. Equipped with a rubber-band motor, the mechanical automaton moves imitating the flutter of a butterfly with no external power source or batteries.
As with every model in the Ugears family, The Butterfly requires no glue or additional tools to assemble. You will build your new model out of ready-made details that come precisely pre-cut in high quality natural plywood boards. Slightly pushed, the details easily pop out of the board.
The Butterfly sits on a flower-shaped platform. The elastic support slightly bounces the model, making its movements more realistic so that The Butterfly dances and flutters in the air approaching the flower.

The model has three modules: the airplane, the helicopter and the flight control tower. Choose between your aircraft, set one on the tower’s bar and you are good to fly. As a beginner pilot you might want to start with the helicopter which is not as difficult to control as the airplane. Easier to manipulate but no less exciting, your chopper has a cockpit with doors that open and shut, and three-blade main and tail rotors. Learn More

The model has three cylinder gears with numbers from 0 to 9 and a Geneva Drive. This combination allows you to see an interesting mechanical feature: when the reciprocating motion of the click-button using the Geneva Drive mechanism turns into the rotary motion of the cylinder gears with numbers. The Counter provides two options of data registering: click-button on the roof of its body, and a turn handle on its side. Pressing the click-button or turning the handle makes the Counter shift by one place. When the count passes 9, the Geneva Drive catches the next register cylinder and adds it to the count. Altogether, the three-digit display of the Counter can register values from 1 to 999. You can open the front panel of the counter and reset it manually. Try counting steps on your way home. Or how many people you meet on a stroll through the park. How about, the number of blue cars passing by your house during one hour? Count stairs at home, at school, or at a friend’s house.

A mechanical gearbox is a reducer that provides speed and torque conversions from a motor to the driving wheels. After assembly, you can experiment with the Ugears manual Gearbox, by turns, choose I, II, III, or reverse with a kinematic pair of gears with different ratios and, rotating the actuator handle clock-wise, you can watch and control the rotation speed of the layshaft and drive shaft. In a Position “N” – idle in which both clutch gears of layshaft remain uncoupled and idling; the First Gear makes the layshaft and gears rotate with the lowest speed; the Second Gear lets the drive shaft along with the flywheel rotate with an average speed and the Third Gear allows the layshaft and all gears rotate with the highest speed. Switch on the Reverse gear and see how the driving clutch gear moves to the left towards gear “R” and connects to it transferring the rotation to the lower gear arrangement and propelling the layshaft and all gears to rotate in reverse.

The pendulum is one of the basic and most reliable time measuring mechanisms. Its working principle is based on the model's constant amplitude oscillation under the force of gravity (weight) and potential energy (tension force) of the rubber band. The rubber band powers the mechanism of the model and compensates for the pendulum's oscillations' kinetic energy loss. The device is animated by means of gear unit with a windup wheel.
The model has an anchor escapement controlling the frequency of oscillations, a weight, a scape-wheel, gearing, rubber band, ratchet, and pawl reducing operation error. The model has several means to control the frequency of oscillations: the weight of the pendulum bob, the vertical position of the weight on the pendulum, and the tension of the rubber band.

A beautifully crafted Nativity Scene model is the Ugears’ tribute to a beloved Christmas tradition. Carrying the true spirit of the most wonderful time of the year, this model is created to make your winter holiday really special.
Almost every country that celebrates Christmas has a tradition of installing a Nativity Scene: a display that features newborn Jesus in a stable with Mary, Joseph, an Angel, and the three wise men. In different places and settings the number of characters and approach to decorating the scene may vary, showing a host of angels, Shepherds, plenty of expensive décor, etc. Ugears created a humble and tender design implemented in wood that best celebrates the birth of the divine child of Joseph the Carpenter.

The Ugears' Vintage Alarm Clock is a charming throwback, a decorative reminder of the mechanical alarm clock sitting on the bedside dresser in your parents' or grandparents' home. When you move the large gear on the side, the arrow hands of the Alarm Clock spin and the bells jangle, giving the wooden clock model its characteristic "clacking" alarm sound. While this decorative wooden model clock doesn't actually keep time, the hands of the clock are geared so that one complete rotation of the minute hand advances the hour hand one position. The clock face features design elements including the sun, plants, curlicues, and a progressing sundial, and sits atop columns that give the whole model an attractive architectural structure.

The main element of the 3D puzzle Random Generator’s design is a cube with an octahedron inside it that in its turn contains a metal ball to provide weight. This construction is powered by a rack-and-gear drive initiated manually and providing energy through a driven gear that rotates a three-axle gear. This is how the cube with all its contents begins to move, which is important for summoning the magic of randomness. Of course, we can only call it magic until we know the science of it. And to learn it, let us take a closer look at the main structure.
The vertices of the octahedron coincide with the sides of the cube. In this way as the energy of the system expires and it stops moving, gravity suspends the metal ball in the lowest part of the octahedron and due to the inclination of the walls it rolls within, it ends up in one of the octahedron’s vertices pulling in down. Whichever of the vertices turns up in the bottom, the side of the cube it is attached to will be right under it and parallel to the floor. In this way, the side of the cube with the answer will be the one facing up on the opposite side.
