View Full Version : Tracking How Far Your Hamster Runs!

It's cool to know how far your hamster has run in his/her wheel!! There are a few of ways to do this!

:arrow: Bike Computer (Difficulty: 2/10)

This is by far the easiest way to track how far/fast your hamster is running! You need to find a bike computer that allows wheel sizes to be customized down to the diameter/circumference of the wheel you have! I have found these before on ebay but can't find one now!! You can always set the lowest diameter allowed and then calculate the distances/speed yourself if the speedo you have doesn't go small enough!

You can then attach a magnet to the wheel and sensor to the cage!

This really is the easiest way of doing it!

:arrow: Pedometer (Difficulty: 5/10)

This requires some slight modification of a pedometer which are a couple of quid at most and sometimes free with cereals etc! Basically a magnet is stuck to the wheel and the pedometer is modified so it counts either clockwise or anti-clockwise turns of the wheel (a simple piece of wire). When the wheel turns the magnet causes the pedometer to register a click!

:arrow: Reed Switch/Computer (Difficulty 8/10)

This is the way I track Horatio. The actual build of the reed switch is pretty easy - you need to solder two wires to a serial post connector though, technically this is as hard as it gets. The hard bit is once the switch is set up and attached to a computer! You need to install some software to run a program found on the instruction pages below, you really need to have a good knowledge of computers!

I would be happy to help anyone embarking on this project!

I've provided some of the detail on how I did it here, including some part details for Maplin:

Sorry to bump the topic, but I just saw this and thought it was such a great and fun idea when you first mentioned it in introductions. So, I'm really glad you posted this, because I'm thinking of having a go with it!

coool!! let me know how it goes - which way are you going to do it? I have ordered a cheap pedometer from ebay to try this method out!
