HOW TO - Fossilize your hamster
This book looks great, here's the blurb from Amazon... -
How can you measure the speed of light with a bar of chocolate and a microwave oven? To keep a banana from decaying, are you better off rubbing it with lemon juice or refrigerating it? How can you figure out how much your head weighs? Mick O’Hare, who created the New Scientist’s popular science sensations Does Anything Eat Wasps? and Why Don’t Penguins’ Feet Freeze?, has the answers. In this fascinating and irresistible new book, O’Hare and the New Scientist team guide you through one hundred intriguing experiments that show essential scientific principles (and human curiosity) in action. Explaining everything from the unusual chemical reaction between Mentos and cola that provokes a geyser to the geological conditions necessary to preserve a family pet for eternity, How to Fossilize Your Hamster is fun, hands-on science that everyone will want to try at home.Amazon.com: How to Fossilize Your Hamster: And Other Amazing Experiments for the Armchair Scientist: Books: Mick O'Hare, thanks David! - Link.

Hacking mice to better control cameras in 3D space
The "Three Blind Mice" project takes three old mechanical mice and connects them up to an AVR microcontroller to feed their input into a PC to control 3D graphics in VVVV. Nice hack with a how-to included.

Phone line controller
Trax writes -
It might be "yet another" «device» controller that operates over phone-line, but this one works for sure :) The task was to build a device that connects to the phone line and has a relay as an output switch. It should also sense if the connected «consumer» is turned-on or off and report to the administrator at the other end of the phone line. The administrator would then call-in the device, log in with the password, and check the state of «consumer», turn it on or off, change password or some other settings. Current version has only one relay.Phone line controller - Link.

KMODDL - Kinematic models for design digital library
Austringer writes -
I was looking for inspiration for a linkage to remotely open the dust collector port on the back of my table saw. What I found was like getting a drink from a fire hose. You have to poke around a bit since they amazing stuff isn't right there on the surface but they have a ton of pictures of static models and videos of the various mechanisms at work. That they have videos of models made using a 3-D printer is like a creamy center made from pure whipped geekyness.KMODDL - Kinematic models for design digital library - Link.

Chaos theory schematic
Ian writes -
In making an electronic circuit exhibiting chaos, one is essentially making an analog computer for the differential equations describing the system. This means that circuits that can differentiate a voltage are needed. In practice, it is convenient to actually do this with electronic integrators, the idea being that the input of an integrator is the derivative of its output. In addition, a nonlinear circuit element must be incorporated, as linear systems cannot be chaotic.Chaos theory schematic - [via] Link.

LED cube from Christmas tree lights
Christmas time is a great time to obtain large numbers of LEDs very cheaply. This instructable uses 80 LEDs from an LED christmas tree light string to make the venerable 3D LED cube. In this case a 5x4x4 cube.

Air mouse initiative beats air guitar
With the "Cornell University Air Mouse Initiative" you can move your air guitar skills over to your PC and jam with the best digital artists this side of the pond. Built as a motion sensing glove with buttons and a PC interface, this project even comes with open source code and a circuit schematic for accelerometer filtering. Just be careful you don't try to win the jamming title back from Bon Jovi's nerdier cousin.

"Under the Misteltoe" - Carl and Jerry, 1958 Popular Electronics
Jeff writes -
I've released another Carl and Jerry free story, this one from December 1958. Carl is sure that a local girl intends to steer him under the mistletoe at a Christmas party and--fate worse than death!--kiss him. Jerry concocts a plan to foil the kiss-crazy girl, but is foiled in turn by his cousin Pat, a true girl-geek who can sling electrons with the best of the boys! - Link (PDF).
More:
What are the "Carl & Jerry - Adventure in electronics"? In the 50's and 60's John T. Frye, W9EGV / Popular Electronics published a series of fiction stories called "The Carl and Jerry stories" - In each story the pair acquired new skills, got their ham radio licenses and used their knowledge of electronics to get out of a jam or solve a mystery - Link.

Solar LED Christmas lights
Wheelgirl writes -
It is getting dark at 5:00 pm, and I have a bike shop signs that needs to be lighted at night during the winter holiday shopping season. So I repositioned a solar garden light ($5) in an Altoids box, cut off and took some pieces from some battery-operated IKEA Glansa LED Christmas lights ($1.98), and made some solar LED Christmas lights that don't require a wall outlet for their power. It was less expensive to modify stuff that had already been manufactured than to start from scratch.Solar LED Christmas lights - Link.

Make a name badge from an old GameBoy printer
Phar writes -
So the local Make:NYC meeting had had a badge contest for its second meeting.. (link here), the gist of the competition is to make a wearable nametag/badge of some sort, of some materials, that could be reasonably accepted as a "badge".. this Instructable is how I built mine for the contest.. pretty much everything that went into the badge was something I had around my workshop from previous projects, and obviously the design can be pushed to do more interesting things. but I'll leave that up to you.Make a name badge from an old GameBoy printer - Link.

TV-B-Gone - testing IR LEDs...
I just made a bunch of the TV-B-Gone kits, one quick test you can do when you make these kits is to press the button and shine the IR LEDs at a web cam, it will show up as a nice purpley color and you know you're device is working if you don't happen to have a TV (I don't). Most CCD or CMOS detectors will show infrared light when you point a TV remote at it, more so if it's a high powered version.
