Ugears STEM Lab Counter

A counter, as an important 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 a road by counting the number of rotations of the wheel.
 
Learn how the COUNTER works
The STEM Lab Teller records repetitive actions. It is an integral part of a device called an odometer. The model has three cylinder gears with numbers from 0 to 9 and a Geneva Drive. With this combination, you can see an interesting mechanical feature, when the reciprocating movement of the click button, using the Geneva Drive mechanism, turns into the rotating movement of the numbered cylinder gears.
 
The counter offers two options for logging data: a click button on top of and a rotary handle on the side. By pressing the click button or turning the handle, the counter moves one place. When the count is over, the Geneva Drive captures the next register cylinder and adds it to the count.
 
Altogether, the three-digit counter display can record values from 1 to 999. You can open the front panel of the counter and reset it manually. Try counting the steps on the way home or how many people you meet while strolling through the park. How about the number of blue cars that pass through your house for an hour?
