There are a few ways to make trapdoors, but out of all of them, this one is my favorite. It's fast, completely hidden, and both opens and closes. This particular trapdoor can be used for a variety of purposes, such as hiding your valuable possessions, having a secret entrance to an underground lair, or maybe even taking care of obnoxious cows. What you'll need to make it are 12 sticky pistons, 8 redstone repeaters, 32 redstone, the switch of your choice, and whatever blocks you want to use to...
Making your own circuit boards can be a daunting challenge. You have to design a schematic, test it on a breadboard, design the board layout, and then after all of that, you still have to print and etch a board!
Here's the trailer for the "Skyjacking" Terrorist vs. Counterterrorist map that I built using redstone for bombs, timers and more features, along with the SDK Gun Mod. If you want to give the PvP map a try, you can download it here. The goal is to defuse 3 bombs within 10 minutes! The last bomb has 2 wires; cut one of them to win—they are randomly chosen by redstone...
Even if you live in a big city, chances are you have some wild raccoons or foxes that cannot abide a vertical trash barrel. While apparently omnipresent, these phantasmic critters usually vanish in the night leaving only a shameless trail of refuse you never wanted to see ever again. While I haven't found a way to stop them, I can help you snap some photos of the dastardly creatures.
Have a few light bulbs and a blowtorch? Then join the folks over at Harvard in a cool science experiment on the conductivity of glass. As you well know, glass is an insulator with low conductivity and high resistivity. In the video below, they flip the switch, demonstrating how heating the glass fuse enclosure from an incandescent light bulb can create a conductive material that completes the series circuit and lights the second light bulb. In the video, the two light sockets are wired in ser...
Spring has sprung, which means it's time to plant all those delicious vegetables and lucrative cash crops. If you are like me, every year you meticulously plan every aspect of your garden before dutifully neglecting it all summer. I decided enough was enough and built this simple automatic watering system.
There is nothing more annoying than a greedy roommate. It's absolutely infuriating to wake up and find the cookies your mother just made for you gone without a trace. Your favorite drink is empty and the homemade meal you worked so hard on the night before is nowhere to be found. This irked me so much that I made this shocking cookie jar. When a cookie burglar touches the side and the lid of the jar simultaneously, a small electric shock stops them in their tracks.

I have to say, the Xbox 360 controller is the best controller ever created. When I first held it back in 2005, I swore that the dudes working at Microsoft came over and took a molding of my hands because of how great it felt. The thing felt like it was born there.

Cheating. It happens everywhere. From scientists faking human ears on mice, to Hollywood thirty-somethings cheating on their quadragenarian wives, to chess players accusing supercomputers of fraud. There's no game or profession out there that doesn't have a cheater or two, but the bigger nuisance is probably those people who accuse others of cheating.
There are many impressive accomplishments in Minecraft, too many to name in fact. Sprawling builds, complex machines, and massive servers are the hallmark of Minecraft and things keep getting bigger and better. No one doubts the epic scale Minecraft has reached, but every once in a while something grand comes along that sets a new benchmark in awesomeness. By far the most recent step in this long line of big ideas was an innovation pushed forward by YouTube user Kimundi2. The premise of this ...
Hello readers again! Sorry about the long wait (scary computer problems). Today I am going to talk to you about security problems on Wizard101. I have recently encountered many security flaws on Wizard101, including hacking, frauding and other crazy things. Wizard101 is the target for many online predators, many of who are fully-grown adults aged 60 or 70. Here is the link to an article I found about it: Wizard101 Internet Predators
Though it's unlikely you'll ever have a need for hostage survival skills, it never hurts to take in a few tips on what to do in the event of being accosted by Somali pirates off the Horn of Africa.

Researchers Hiroto Tanaka and Isao Shimoyama (of Harvard University and University of Tokyo) have constructed a tiny replica of the swallowtail butterfly. The crudely made model uses just balsa wood, rubber bands, and a steel wire crank. The goal is to better understand the biomechanics of butterfly flight. Via Wired,
Texas based photographer Adam Voorhes takes four objects (telephone, frog, gun, etch-a-sketch) and dissects them for his photo essay entitled Exploded. The frog in particular looks like an illustration, but is indeed a photograph.

Plaster walls, although popular homebuilding materials, are notoriously easy to damage. Door handles, elbows and moving furniture are all great at putting holes in plasterboard walls, holes which, thankfully, only take an hour or so to patch up. Stumped as to how to do it? Watch this video tutorial to learn how to repair these holes on your wall.
A sink full of slow draining water, or even worse, no drainage at all, is a sure sign of blocked pipes. Blockages are due to all those scraps of food and crumbs that get down the plug hole everyday. Yuck. Watch this video tutorial to learn how to unblock a sink. You will need a good sink plunger, an adjustable wrench, a bucket, a strong wire, gloves and some disinfectant to finish up.

In this video watch Michael Zbyszynksi, explain how to make carrot caviar in this video. He starts with a beaker of ordinary carrot juice mixed with sodium alginate -- a derivative of seaweed -- at a ratio of 2 grams of sodium alginate to 250 grams of carrot juice (a 0.8 percent solution). He then uses a syringe to drop small beads of the solution into a bath of water with a couple grams of calcium chloride dissolved in it. The calcium chloride hardens the sodium alginate from the outside in,...
Some think of Google as the ultimate Big Brother, and with good reason. If you use Google (and most of us do), Google potentially has your email history, your complete search history, your travel routes, your interests, and more. Maybe they've even snapped a picture of you out in the real world (via Google Street View).
By trial and error, I have found a good way to remove the door panel from a 2002 Ford Explorer (and other similar years).

If your bicycle's feeling a little dull these days, then give it some personality! Using the crafty ideas below, you can transform your two-wheeler in a unique work of mobile art that will have everyone jealous.
This article is dedicated to sugarcane, because we all want more sugarcane in Minecraft. The best way to generate sugar cane is with an automatic reed farm that uses pistons and redstone. The pistons push the canes into the water canal you'll build, then delivers them to the collection point at the end of the canal.
What started off as a meme, has turned into a near reality. When the E3 trailer for Battlefield 3 was released this summer, it started off with a soldier holding up a dinosaur statue. Obviously, this means that DICE (the developers) should release a DLC pack where you're fighting dinosaurs. This is the next best thing, I guess. DICE, if you're listening, I've got loads of ideas for the dinosaur DLC.
Congratulations to Bryan Kiguchi for Dreaming Little Bird, our winning shot of the Phone Snap Double Exposure Challenge!
Sometimes entrepreneurial inspiration comes from the oddest of places— such as, say, down-and-out crack dealer delivery methods. Inspired by HBO's The Wire, Kathleen and Clem of Fat Cookies are attracting a crowd with an atypical model for vending baked goods: oven fresh cookies are lowered via string in exchange for one hoisted dollar (1. pull a string, 2. attach a dollar, 3. get a cookie).
ScienceDaily (Oct. 17, 2009) — Learning to juggle leads to changes in the white matter of the brain, an Oxford University study has shown.
