Your hamster lives to good life, with food delivery and a maid service that cleans up after him. [DanF] helped to brighten up this hamster’s life even more by improving its exercise equipment and giving it a small night-light as well. This project adds a low RPM alternator to the hamster wheel.
The first part of the process was to reduce energy lost to friction by fitting the wheel with a bearing. From there a ring of permanent magnets was added which will pass by a stationary coil and induce a current. It works, but unfortunately there’s not enough power generated to charge a battery. That means the light is only on when the hamster is running. But maybe you can figure out a way to use a super-capacitor like we saw in that exercise bike hack.
One nice finishing touch to the setup is a bicycle computer to track how much time was sent on the wheel, and the distance traveled.
[Jacob] sent in his teams final project, Project 413. While sounding like something straight out of an action movie, don’t worry, it’s not the next terminator. Rather a combination of an eBox (in place of an EEE pc), omni wheels, motors, batteries, and the finishing touch – a hamster ferret ball. If this is sounding familiar to a certain web comic, then right you are, as XKCD was their main inspiration. Sadly, the web cam and ‘having a soul’ functions didn’t make it into their version, but being controlled via Wii remote is always a plus. Check out a video after the break.

We had a lot of entries for our Fail contest; there can only be one winner though. We liked [Gordon LaPlante]‘s entry pictured above most of all. It’s big, it’s broken, and it’s black and white; that certainly sounds like us. [Gordon] wins $100 worth of No Starch Press merchandise.
There were plenty of other honorable entries. You can view them in the Hack a Day Flickr photo pool. We saw a couple themes emerge during the contest and have highlighted some of them after the break. Continue reading “Hack a Day Fail Contest Winner”
