Track How Far Your Hamster Runs

Have you ever wondered how far your hamster runs each day? Most hamsters (like mine) love their wheels. What if there was a way to track how far your hamster ran in its wheel? Well there is! And all you'll need are a few dollars in parts that you can pick up at a hardware and electronics store and a computer. Follow this Instructable and you'll be tracking your hamster in no time!

Step 1 Get a Hamster and a Wheel

If you don't already have one get (1) hamster and (1) hamster wheel. I got a Syrian hamster named Lizzie and a "Wodent Wheel". Apparently this type of wheel is better for her back because of the relatively large radius.

I am making something similar to this for my pet hedgehog. Instead of hooking it up to a computer, I'm going to use a calculator as described in this instructable:

no matter how thick your wire, do not let your hamster anywhere near it. that's very important.

[harry88]

could the magnets kill your hamster

[sbreed]

No, magnets will not hurt a hamster. The fields used for MRI use magnetic fields that are much larger, and are used routinely in hospitals.

[sci4me]

that makes me wonder about this project... hmm...

[ReCreate]

Ummm...can  you upload it somewhere else?

[sharlston]

like my hamster?

[dduke11]

Looks like its ready to run!

[sharlston]

shes not exactly the sort of hamster that will sit down and watch tv so ye she enjoys running

[tmr]

Oh man...if I ever get a hamster, I'm making one of these.

[tristantech]

Does the python program run all the time on your comuter in the background? or do you start it at night and stop it in the morning? Also, won't writing a file every revolution wear down the harddisk? I've seen hamsters run in wheels and they pretty darn fast...

[dduke11]

Yup, it runs continuously on my computer just in case she runs a little during the day as well. This won't really wear down a hard disk any faster than normal. While hamsters look fast to you and I, there are programs that write data much more quickly than the hamster can run.

it,s good

You could also just buy a bike spedomiter and put it on the hamster wheel. You can get cheap ones for about $10. Nice instructable, though.

[Redgerr]

thats true too, although it may not work on such a small weel :o

[I_am_Canadian]

You can usually just set them to the MM in width, and Mine can go down to 1 MM. THat would be a small wheel.

My daughter and I got a bike speedometer to work with her hamster wheel without much trouble. The speedometer was set up so you could calibrate it to any wheel diameter using a little table. We were astounded to find that our hamster was running 5 to 8 miles a night!! At first we thought we had made a mistake, but we found a few people on the web with similar results. It worked great and was really easy and fun- the only thing we would change is that we we would add some kind of protection to the wires leading from the wheel to the speedometer - the hamster eventually got bored and chewed through.

[mtdna]

more... My post made it sound like our hamster died from chewing through the wires. It was fine. The wires don't carry much current; just a little signal from the wheel.

[blahblogmister]

small question: what speedometer did you use? i am trying to find a good one for my hamster wheel.

[mtdna]

It's been a while, so I'm not exactly sure. Judging from the pictures and prices of the different speedometer/odometers on Amazon, I'm pretty sure it was a "Bell SpinFit Calorie Bike Speedometer", which costs around $15.00.

[blahblogmister]

oh sweet thanks so much :)

[Redgerr]

good i thought he died lol

[I_am_Canadian]

Cool! I would do this with my guinea pig but she runs about 2 meters a week, so Im not so sure that it would be worth it. 8 miles! Thats a lot! Farther than I run... A lot farther.

[Redgerr]

lol, probibly not faster... the hamster has all night to do it :P you may olny have a while :)

[I_am_Canadian]

True, but still...

[Redgerr]

lol :) pwnt me eh? :D

[Redgerr]

lol, okay :P u might be right, idk much about it ;)

[I_am_Canadian]

Me neither. MY guinea pig is way too lazy to use a wheel...

[Redgerr]

thanks lol :)

[casey321b]

i see a dead hamster next to a chewed up wire.... uh ohs not good.

[dduke11]

The wires are actually have incredibly little power going through them, only 5 V and about 10mA. That is way to low to cause any harm to hamster or person.

[PKTraceur]

15 mA kills a human... -PKT

[dduke11]

The key here is voltage. If the current cannot flow then it is harmless. If you touch any of the ports on the back of your computer 5v is what you'r touching. That's what's going through these wires.

[bigdukeydog]

Great idea and nice job presenting!

[p2kyrock01]

prettty difficult to me... nice project. i wonder how far my hamster can run

[ReCreate]

Can you just give me the compiled EXE instead of me having to do it from scratch?

[ReCreate]

So this can determine the RPM's of a spinning object? I think i just sparked an idea...

[Yashichu]

Awwwwa! I wish had the time to create something so neat like that. Instead I brought a bike computer to do the work.. Though I did have the time to set up a website of my own also n.n

[puffin99]

This is so cool - I really want to do this but am failing when it comes to the writing programme bit... I know its cheating but does anyone know where I can download these? or get a step by step how to set this bit up? Please help....

[Robil]

Very cool ible. You may want to consider counter-weighting the magnets... to Lizzie, the difference could be enormous (imagine running over a thousand little hills).
