News: My redstone elevators
Hi, my name is Matthew9170 and I would say I am a decent minecraft redstone engineer. I am entering the Elevator Redstone challenge. I have 2 entries on a double plot of land in the opposite corner of the /warp tower.

Howdy, hobos! Last week's WTFoto challenge meandered on much like its namesake, the vagrant. We had a couple good submissions that warmed my heart with laughter. I thought my examples were pretty on point, but my confidence is pretty low right now because I failed a recent IQ test. For your amusement, here are those awesome remixes of the Hobo Image Macro! Did they measure up?
This is the third part of my electromagnetic pulse series (see Part One and Part Two). By now, I've covered the hardware and general concept of electromagnetic pulse generators, but how exactly do they disable electronics? How can an invisible field of energy have such a catastrophic effect on computers, cell phones, and most any other electronics? I'll be answering all these questions in part three of Making Electromagnetic Weapons.
It's Monday, which means once again, it's time to highlight some of the recent community submissions posted to the Math Craft corkboard. I also thought that we'd try and create something known as an "Orderly Tangle" or "Polylink".

Over the past 10 months the once peaceful city of Christchurch in the South Island of New Zealand has been haunted by a plethora of devastating earthquakes with hundreds of fatalities. To date there have been over 7000 earthquakes. This photo was taken on Worcester Boulevard, opposite the Christchurch Arts Centre. It was a dull, cold day, so I used a monochrome 'film' which captured the sombre mood of a mourning city; this was coupled with underlying parallelisms of an angled shot emulating t...
Sometimes an "analog" result is highly satisfying when the means for producing it is just the opposite. Enter Niklas Roy's "Electronic Instant Camera" project. The endeavor combines an analog black and white videocamera with a thermal receipt printer. The outcome is something in between a Polaroid camera and a digital camera. Like the olden days, the subject must sit still for a quite a while—3 full minutes—as their image is recorded and printed directly on a roll of receipt paper.
Researchers at Northwestern University have hatched a robotic replica of the ghost knifefish, an amazing sea creature with a ribbon-like fin, capable of acrobatic agility in the water. The fish is distinctive in its ability to move forward, backward and vertically, but scientists didn't understand its vertical movement until the creation of its robot replica, GhostBot (shown below). They now know its vertical propulsion is caused by two waves moving in opposite directions, crashing into each ...
In this video tutorial, viewers learn how to drift a car. Viewers will learn 3 different ways of drifting. The first ways is the handbrake turn. Begin by building up speed in the first gear, swing the wheel over sharply, pull the handbrake, dip the clutch and release the handbrake. The second way is the 90 degree turn. Begin by driving in the second gear, nip the handbrake as you approach the turn, opposite lock and accelerate out of the slide. The third way is the handbrake turn into the rev...
This is one serious example of trophy architecture. Extreme engineering in prosperous countries like this one in Singapore is meant to stir envy. The Marina Bay Sands infinity pool opened this month, and is located 200 meters off the ground, 150 meters in length. The entire hotel complex is part of a $5 billion investment, and the opposite of a DIY sensibility.
The outside hook utilizes what is called the "dummy": feigning to go one way before going the other. This psychological compoment is extremely imperative for successfully bypassing your tight marker.
In order to score a goal and keep the ball with their grasp, attackers master the art of the inside hook. A simple trick that's simply effective, it involves feigning that you're moving outward when you're realling taking the ball in. The move has been mastered by Turkey's Emre Belözoglu.
Pimpmywalk will show you how to do the c-walk dance the shuffle. You start by putting on foot flat and the toe of your other foot up. You then alternate that movement going from on foot to the other. You keep putting one for flat and then the toe of the opposite foot up. You then kind of hop to the next foot. In this video you can see the feet of the dancer so you can properly achieve the move. Just keep switching feet and then you have just completed the shuffle dance. You are shown the move...
Start by lying on your side on the floor or mat with the legs extended. The elbow should be directly underneath the shoulder to support the body. As you contract your abdominals, use your torso to lift yourself off of the mat while your elbow and feet are touching the ground. Hold this for 10 to 15 seconds making sure that the spine and neck are in a neutral position. Repeat on the opposite side.
Start by lying on your side with the knees bent. The elbow should be directly underneath the shoulder to support the body. As you contract your abdominals, use your torso to lift yourself off of the mat while your elbow and knees are touching the ground. Hold this for 10-30 seconds making sure that the spine and neck are in a neutral position. Repeat on the opposite side.
It was brought up a while back in a Community Call to Arms that *math* is handy for encryption (and let's face it, everything) so let us go over things you just have to know. "In its simplest meaning in mathematics and logic, an operation is an action or procedure which produces a new value from one or more input values."[source]
Many people get so discouraged by their failures with redstone that they give up using it entirely, or never progress beyond using simple switches. However, by incorporating logic gates into your redstone designs, the applications are nearly limitless. The ability to add multiple switches to your machines is just a small part of what logic gates can do. Most importantly, they give you control.
When he's not taking orbital videos of Earth's auroras, NASA Astronaut Don Pettit is experimenting with water in zero gravity. He's already shown us how water droplets can orbit around knitting needles in a microgravity environment. Now he's playing with water again, this time—antibubbles.
We've all heard of the power that red wine holds. It can help lower risks of heart disease, boost your brain power, and can even recharge your car battery. But last year, a group of Japanese physicists made headlines when they announced that they could induce superconductivity by soaking metals in red wine. But why red wine?
Nikola Tesla. He was the man behind some of the greatest inventions of all time, including radio and alternating current. But perhaps his most visually fascinating invention is the Tesla coil. While maintaining a low current, it can produce dangerous high frequencies and voltages that can well exceed 1,000,000 volts, discharging it in the form of electrical arcs very similar to lightning.
Math Craft admin Cory Poole posted instructions on How to Make a Cube, Octahedron & Icosahedron from Sonobe Units, plus some great complex models in his article, How to Make a Truncated Icosahedron, Pentakis Dodecahedron & More. These models use the standard sonobe unit and a coloured variant.
Dungeon Defenders is finally out on the PC, Xbox 360, and PS3. We've previously featured the tower defense RPG, and if you haven't had a chance to check out the PAX interview with Trendy Entertainment, now would be a good time.
Sometimes mining and crafting gets boring. The thrill of hunting mobs, exploring strongholds, or the Nether is often much more satisfying and appeals to the RPG nerd in all of us. Well, Mojang took the hint and as part of the 1.9 release, there will be potions, more mobs, other worlds, and enchantments added to the game. To preview this release, read my tutorial on how to download and install 1.9.3.

Before jumping right into becoming the next James Neely or Moose Peterson, you're going to have get situated with your new digital SLR. No matter if you purchased the Canon EOS 5D Mark II body and lens separately or together, you've got everything you need to get started except the CompactFlash (CF) card. If you plan on shooting in RAW or capturing HD video, I suggest getting an 8GB or larger CF card. If you can afford it, maybe even opt for a high-speed UDMA card.
Flying orbs. At first, you might think of the Tall Man and his army of flying sentinel spheres, equipped with zombie brains and a mini-arsenal of saw blades, drill bits and shooting lasers. But these flying orbs weren't conceived from the evil mind of a superhuman mortician—they were designed by Fumiyuki Sato, a researcher at the Japanese Defense Ministry's Technical Research and Development Institute—for something other than deadly deeds.
It's more addictive than Angry Birds, perhaps as relaxing as transcendental meditation, and satisfyingly simpler than GarageBand. It's Otomata, a newly programmed generative sequencer designed by Batuhan Bozkurt, a Turkish sound artist, computer programmer, and performer. But really, it's best described as an audio/visual music toy that anybody can play online—with beautiful results.
My mind is playing tricks on me! Discover Magazine systematically dissects five fantastic optical illusions. The scientific explanations are logical:
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,
If you are looking for something different for the back muscles, consider the alternating pullover exercise. The largest muscle in the back is scientifically known as the latissimus dorsi. You might see it referred to as the "lats" or "wings." The lats are used any time you pull something. For example, when you open a fridge or a car door, you are primarily using your lat muscles. Here is how this exercise is done:
Assisted pull-ups, as the name implies, allow you to perform pull-ups with help. In this exercise, the help is in the form of heavy duty rubber bands. This version of the pull-up is a great alternative for those who are unable to perform a traditional pull-up.
The hip roll is great if you are looking to target the midsection. This exercise is used to target the oblique muscles, which occupy the sides of the midsection. The job of the obliques is to assist with rotation of the torso, as well as basic abdominal contractions.
The ball weave is great for the core. This exercise looks flashy, but in reality, your abs are in a static position the whole time. There is very little movement in the midsection. The ball weave is easy perform, but it does require some coordination.
The seated leg extension is used to isolate the quadriceps muscles. The quadriceps muscles are located on the front of the thighs. As you might have guessed, there are four muscles that make up the quadriceps. Each muscle works in unison to extend the knee. In everyday life, the "quads" are used when you jump, walk, sit, kick, or stand.
Here is an exercise that really works the gluteus muscles. It is relatively easy to perform. However, for this exercise to be effective, it does require a bit of skill and proper technique. A workout mat is recommended.
The gluteal muscles, or glutes, can be targeted with donkey kicks. This exercise is easy to perform and does not require any fancy equipment. The donkey kick is a classic "butt" exercise, and there are many variations of the original donkey kick. Instructions for the donkey kick exercise are listed below:
If you want to improve balance and strength in the leg muscles, try the single leg deadlift (also called the single leg Romanian deadlift). This exercise is primarily going to work your hamstrings and butt. The single leg deadlift comes with a high degree of difficulty because it is performed on one leg. An advanced level of balance and muscular control is required for this exercise. Here are the instructions:
