UGEARS STEM LAB COUNTERModel Size: 13.5*6.5*12.2 cmNumber of components: 157Estimated time for assembly: 2 hoursAssemble the Counter and discover the principle of a working Three-digit Clicker-Counter Experiment: the model comes with a QR Code to download an interactive Pocket Model Study Guide which includes engaging and interesting tasks to learn more about how a Counter works.Immerse yourself in Augmented Reality (AR), find out how the Counter is used in a production line, and interact with it via the dedicated Ugears application.Learn how the COUNTER worksThe Counter is a stylish educational model, which includes an interactive study guide, to help learn and understand the principles of how a Counter works.The Ugears Counter consists of a click button that is used to register values, a Geneva Drive that sets the whole mechanism in motion, Cylinder Gears with Numbers, and a Turn Handle. The Counter can register values between 1 and 999. You can then 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 for one hour? Count stairs at home, at school, or at a friend’s house, the options are endless.When and who invented itA counter, as a key part of the odometer mechanism, was invented by an Ancient Greek mathematician and engineer Hero of Alexandria who lived in 10-70 AD. It measured the length of the path by counting the number of rotations of the wheel. Later, the counter was improved and completed with a reducer that reduced the number of the wheel’s revolutions depending on the measuring system (miles, leagues, kilometres) and showed reduced data on the display.UsageThese days, counters are used to count the number of passengers, visitors of different events, cars passing through certain check point, sets and scores in sport, items on a production line, etc.The Counter is developed to serve as a learning tool rather than a puzzle.Just like the rest of Ugears collections, putting STEM-lab models together is fun and comprehensive: everything you need to build, learn, and discover comes in a box. There you will find: High-quality wooden boards with pre-cut details and other standard supplies. Assembly requires no glue or additional tools. The details come out of the boards with a slight push. Detailed step-by-step colour instruction manual. Easy to follow – easy to learn. Examples and suggestions for your fun hands-on projects.
