Have you ever wondered just how much your hamster runs throughout the day/night? How far? How fast? My 9 year old daughter did, and we decided to find out. Turns out, it was pretty easy, and the results were unbelievable.

Laser Break Beam Sensor: Laser break beam sensors are usually kind of cumbersome. They work by detecting an object breaking a laser beam – but you usually have to set up a laser on one end and a sensor on the other. Unless your sensor is big, it can easily get out of alignment.
…but not this break beam sensor. It has a light sensor+lens next to the laser to detect the reflected dot when the beam is broken, so it can sense when someone breaks the beam from the starting location. There’s no need for a matching end point sensor! It forms a good strong laser with a sensing distance of up to 1 meter. We found that it can go a little further depending on the ambient light and the color of the thing distrupting it. You’ll want something that is good at having the dot show up soft textures may not work as well. We used a hand, paper, or cardboard box with great success!(read more)
