Dive deeply into the STEM theories & workings of a Mechanical Counter.

Mechanical Counter model building kit

Learn STEM the fun and hands-on way with our STEM kit series. You'd be learning all about the Geneva Drive in a Mechanical Counter, and how its gear mechanisms track count.

Go a step deeper with our AR experience app and our study guide which completes the STEM learning journey.

STEM Mechanical Counter


  • Mimics an actual triple digit counter - It has a tri-cylinder gear setup with counting numbers (0 to 9), powered by an internal Geneva Drive. 

  • A complete STEM learning experience - On top of our usual fully colored instructional manual, we've designed a STEM-inspired pocket study guide about the mechanical counter. It includes:
    • Detailed breakdown of the counter's mechanisms, scientific principles & formulas, features and definitions. 
    • Examples of real world applications.
    • Exciting hands-on projects.

  • An Augmented Reality experience with our App - Included in the kit is an access key which grants access to our AR experience with the mechanical counter, and its real world applications. Simply download our App and point it with your fully constructed model to begin. Full instructions are in the kit.

  • A deep learning experience about a counter's inner workings - Remove the mechanical counter's outer cover to reveal the parts that make a counter work. From the click-button, cylinder gears, Geneva Drive and the turn handle, watch how the gear motion translates a continuous rotation movement into intermittent rotary motion.Mechanical counter model kit
  • Counts and resets with ease -
    • Counting: Each click of the counter registers a count by causing the internal gears (powered by the Geneva Drive) to shift the counter down by a digit. It registers values from 1 to 999. 
    • Resetting: Open the front panel of the counter and reset it manually by turning all the digits back to 0.

  • No extra tools or glue required - Everything you need to construct the mechanical counter is provided in the kit. Simply unbox & dive straight in.

  • Dimensions: 5.3" (L) x 2.6" (W) x 4.8" (H)

Package Includes:

  • 157 x Birch wooden pieces
