The “Little Drummer Boy” On a Scanner and Drum:

There’s little more information on this hack, however, it’s quite interesting seeing an automated drum and a scanner playing a familiar Christmas tune.  Check out the video of the duet in action!

A Radial Engine Model:

Through the process of experimentation, two “radial engine models” were produced.  The engine model shown above uses a gear-reduced motor to power it.  The other model uses CNC-cut gears and a motor from an air freshener!

Tips and Tricks on Repairing LCD Monitors:

So do you have a broken LCD monitor? Using techniques described in his post, [Neoxity] claims to have been able to repair 50 out of 60 broken monitors using techniques described on his blog.

Flex Cables:

While we’re on the subject of [Neoxity's] page, why not check out his discussion on “flex cables” used for DIY.  Like the humble resistor, they’re not glamorous, but you’d be hard pressed to find an electronics assembly without one.

Illegal Numbers:

Although not a hack in itself, the “illegal number” is a really interesting concept (mentioned by one of our readers in the comments).  Since all data and programs can, at their core, be represented by a series of 1s and 0s, this can also be interpreted as a number.  Thus, some numbers actually represent copyrighted or trade secret data that would be illegal to possess.
