Can’t sleep because of a noisy hamster wheel? Felipe shows you how to easily make a very silent homemade hamster wheel using an old hard disk drive:
Felipe La Rotta from Cocodrilabs had a noisy hamster wheel. Hamster wheels like most other mass produced pet items are made as cheap as possible, that means that you won’t find a smooth spinning bearing in your hamster wheel. His solution was to make a Hard Drive Hamster Wheel. Most of us have a few used hard drives sitting around that will never be powered up again and inside there are a ton of precision parts including a very smooth bearing that turns out to make a great hamster wheel upgrade. Once you have upgraded your hamster wheel if you still have a few hard drives left have a look at some other Hard Drive Hacks that you can try.
