Math Makes for a Perfect Tree: DNews Nugget

Dnews-nuggets-278x225Makes Makes for a Perfect Tree: This is truly for the meticulous, most fastidiuos Christmas tree decorator, who really must have just the right mix of lights, ornaments and tinsel distributed perfectly on the ole Tannenbaum.

It is a mathematical formula that one can use to design the most perfect tree. It was created students Nicole Wrightman and Alex Craig of the University of Sheffield in the U.K. Their "treegonometry" takes into the account the height of a tree in order to calculate the ideal number of ornaments, length of tinsel, length of lights and location of the star on top.

Get out your calculator, folks. Here it is:

  • Number of baubles = √17 / 20 x (tree height in cms)
  • Length of tinsel (cms) = 13 x Π / 8 x (tree height in cms)
  • Length of lights (cms) = Π x (tree height in cms)
  • Height of star/fairy/angel (cms) = height of tree in cms /10

Happy decorating!

House-sized Angry Birds Lights Up Holiday

AngryBirds

Before signing off to enjoy the holiday season, it seemed appropriate to leave you all with a festive piece about a very angry holiday lights display. The Angry Birds craze is still going strong, so much so that Ric Turner, a former Disney Imagineer, created a playable version of the game on his house using Christmas lights. This isn’t the first time Turner has created an interactive light show; two years ago he made a similar Guitar Hero display.

BLOG: Angry Bird Catapulted Into Space

This year’s show runs on two computers and 10 Light-o-rama 16-channel controllers. Audio for the game is broadcast on a radio station, 99.1FM, and even includes a game controller whose cord is long enough for visitors to play in their cars when driving up for a peek. This house-sized version of the game uses 20,000 lights, but it's more energy efficient than one would think. It uses less than 1 cent of electricity per game. Check out the video below for the full experience.

For the Spy on Your List: Gift Guide 2011

Gadget-spy-gift-guide-2011-622

If you know someone who's trying to stop an evil genius or evade capture from a group of well-organized, poorly trained criminals, and you have NO idea what buy them for the holidays, look no farther. Discovery's 2011 Gift Guide for the Wannabe Secret Agent offers suggestions that will please even the best secret-agent-wannabe on your list.

All good spies know how to capture video or pictures of the enemy. Without evidence, how will they escape the frame up? Luckily, the gift guide includes several options to secretly acquiring images.

Consider the worlds smallest camera by Hammacher Schlemmer, which is the size of a marble, weighs only half an ounce and can take 2-megapixel photos and video at 30 frames-per-second. It has automatic focus and only one button for simple operation in the field. Hopefully, it doesn't get too dangerous, because the camera comes with a lifetime guarantee. It's priced at $99.95.

Even smaller is the digital video pen-camera from The Sharper Image while infiltrating the embassy. Record your target's next meeting and get it on YouTube before he releases the poison gas. Piece of mind for $99.99.

PHOTOS: 10 Trickiest Spy Gadgets Ever

If it's a document hoard your spy has uncovered, he will need The Sharper Image's portable scanning wand, too. Much less bulky than the average scanner/printer/fax machine at the office, the wand is only six inches long and, with a wave, can scan documents or photos, saving up to 16 GB worth of documentation. It's also $99.99.

Once the covert data is stored on a safe-house computer, your agent will want to keep the digital data from being compromised. The Eikon Solo Fingerprint Reader from AuthenTec goes beyond password protection, providing access to computer files only to the person whose fingerprint has been stored in its memory. Get it for $19.99.

A good secret agent knows that while going under cover is essential, so is looking good. A bulletproof jacket by Miguel Caballero (alias: "Armani of bulletproof clothing") will keep your spy looking suave -- and free of holes. This bit of sexy protection is available as a vest, jacket, button-down and even a t-shirt.

Being prepared for that last-minute trip to Berlin is crucial for the aspiring cloak-and-dagger. What better place to store small pieces of equipment than in a ThinkGeek book vault? No one will ever expect that the dogeared copy of How To Win Friend's and Influence People contains valuables. Available from ThinkGeek for $34.99.

For the DIY MacGyver, the Discovery gift guide even includes Mini Weapons of Mass Destruction 2. If Mini Weapons of Mass Destruction wasn't enough, why not grab the sequel? With blowguns, periscopes, catapults and bugging equipment your agent never be without the right tool for the job. Perk: everything in these hallowed pages can be constructed with household items and office supplies. The guide is only $16.95.

PHOTOS: Spies Can Hide Secret Messages in Bacteria

Once a mission is complete, every secret agent needs to make a hasty getaway. Few getaways could be more hasty than one in a Corvette Speed Boat. Marine Technology Incorporated might sound like a front company, but they're legit. The speed boat was inspired by a Corvette and looks the part. For only $1.7 million, the ZR1 sports 2,700 horsepower and an 8,000-watt audio system complete with Wi-Fi and AppleTV. In case you're balking at the price, it comes with a trailer. You supply the water.

The only thing the gift guide doesn't provide is a good pun for the moment when your agent triumphs over his or her worthy adversary.

Have Yourself a Solar-Powered Christmas

Solar-xmas-650x400

A Christmas tree lot in San Diego claims to be the first in the world to get its energy from solar power. Using a Mobile Solar Station provided by Stellar Solar, Purdy Tree Farms' Christmas tree lot officially runs off renewable energy.

The Christmas tree lot is also trying to conserve energy by using compact fluorescent light bulbs on all of their trees, according to Treehugger.

Michael Purdy, the owner of Purdy Tree Farms, says his tree lot has always tried to be environmentally friendly. In a press release, he says, "We use sustainable farming practices on our farms in Oregon and have moved towards making our lots even more environmentally friendly with CFL lights and electric chainsaws. Having the lot powered with solar panels just takes that even further."

Environmentalists like myself still haven't ended the debate over whether it is greener to use a real Christmas tree, or reuse a fake Christmas tree every year. But it is definitely good news to see at least one Christmas tree lot switching over from fossil fuels to solar power.

This might be the only solar-powered Christmas tree lot in the world, but a Christmas tree in an aquarium near Tokyo is powered by an electric eel. Talk about alternative energy!

Energy-saving Christmas tree lights are getting more popular this year, too. LED Christmas lights are supposed to last longer and save even more energy than traditional bulbs.

Stellar Solar released this video to show how the solar-powered Christmas tree lot actually works:

Rocking Out With Christmas Lights

Christmas-light-1Tired of the same old Christmas lights displays? Bored by animatronic Santas waving listlessly? Not impressed with the giant inflated snowman on the lawn? Maybe you should take a musical cue from Ric Turner. 

Turner, a contract worker with Disney Imagineering, decided to take on a cool hacking project. He coupled his love of the holidays with his interest in engineering to create a new twist on the Christmas light display. 

Christmas light displays coupled with music aren't a new fad. There have been many impressive displays designed over the last several years. Some of them required thousands of dollars worth of equipment to construct. To avoid annoying the neighbors (and inviting visits from the local constabulary), many of these displays use a weak FM transmitter to broadcast a radio signal. People who drive by can tune their radios to the proper frequency to get the full effect of the display.

LED Christmas Lights are Magical

LED-xmas-lights-278x225 This weekend I did a little Christmas shopping and decided to pick up some LED Christmas lights. LED lights offer several benefits over incandescent and even compact fluorescent bulbs. 

  • Long-lasting. My box of Philips blue icicle lights claims that these bulbs will last 25,000 hours.
  • Durable. LEDs are solid and hold up well under conditions that might break other bulbs or jar their filaments.
  • No Heat. Incandescent bulbs get hot; LEDs stay cool.
  • No Mercury. One of the problems with compact fluorescent bulbs is that they contain mercury, a heavy metal that is poisonous. LEDs do not contain any heavy metals to harm people or the environment.
  • Efficient. My string of LED lights is rated to 7.2 Watts. According to the box, I can connect up to 29 strings for one outlet.

That's all good stuff. I'm just wondering about the quality. In some initial searching on this product, I came across a few reviews saying that these lights last just one season, when used outdoors. The wires seems to rust and even some strings did not work right out of the box.

My strings did work and I'm using them indoors, so I'm hoping they'll last more than one year. And the effect with these particular lights is truly magical. The blue LEDs cast swirls and circles of light onto the walls. Even with the blinds closed, the light effect is even magical from the street.
