The Mechanical Addiator is a compact calculator (or adding machine) that works by moving its rails with the help of the punch included in the kit. By moving the rails, which are marked with arrows and the digits 0 to 9, you can perform addition and subtraction operations.
The mechanical multiplier is a flat tilting mechanism that performs binary operations with numbers. By moving the two tabs, you can multiply or square numbers between 1 and 12, making multiplication tables fun.
Number of pieces: 117. Difficulty: Easy. Assembly time: 2 - 2.5 hours. Recommended age: 8-10 years. Box dimensions: 20.5 x 18.8 x 6.3 cm. Addiator dimensions: 21.5 x 11 x 2.3 cm. Multiplier dimensions: 24.8 x 25.5 x 25.5 x 4 cm.
The counter offers two data recording options: via the button on the body top, or via the rotary handle on the right-hand side. By pressing the button or turning the handle, the counter advances one unit. When it has reached 9, the Geneva drive engages the next recording wheel and adds a ten (or hundred) to the count. In total, the three-digit counter display can indicate values between 1 and 999. You can also open the front cover of the counter and reset it manually.
Other uses of this mechanism include counting flight passengers, event visitors, or shopping centre or public transport customers in large cities. It is an ancient tool that was invented by an ancient Greek engineer Hero of Alexandria. In this case, it was used to measure the distance travelled by counting the number of rotations of the wheels of a wooden cart.
You can also give it different uses by using your own imagination: try to count the steps you take to go from one room to another in your house, or the number of people who pass in front of your window in a given time. Or how about the number of yellow cars you see on your afternoon walk? Or count the number of kilometres on a stretch of road, and compare it with the number of kilometres the car has counted.
To assemble any set in the UGears STEM Lab series, you'll need a pocket study guide, an illustrated manual, wooden boards with pre-cut puzzle pieces and some additional materials. All this is included in the box, and it's all you need to get started. You won't need glue or anything else that doesn't come in the STEM lab box.
Once the project is ready, you can look beyond the assembly process, and study all the real-life applications of the pendulum through the augmented reality experience provided by UGears' STEM Lab application. Aim at the puzzle with your phone or tablet, and see how this mechanism is used in various machines. You can also zoom in with your fingers and see how it works from different angles.
The abbreviation STEM stands for Science, Technology, Engineering and Mathematics. It is an innovative approach to teaching these disciplines through a practical demonstration of the key principles of scientific law. The UGears STEM Lab series presents 3D models based on this learning method. Through a series of exciting experiments, children and adults will be able to more easily understand science, and the logic behind the mechanisms that surround us in our daily lives. In addition, the STEM method allows students to develop problem-solving skills, critical thinking, creativity and much more.
