Hamster Run-O-Meter

If you have a pet hamster, you’re likely to have one of these in its cage: a hamster wheel in which they can run to their heart’s content (or to the annoyance of their owners at night). For the electronics hobbyist this begs for some experimentation. Not on the animal of course (that’s for the biological scientists), but on the wheel. In this simple project we show you how to log its top speed and the total distance it covered.

This stand-alone data logger displays pressure, temperature and humidity readings generated by I²C-bus sensors on an LCD panel, and can run for six to eight weeks on three AA batteries. The stored readings can be read out over USB and plotted on a PC using gnuplot.
