How to Make a Three-Pendulum Rotary Harmonograph A harmonograph is a mechanical device that uses swinging pendulums to draw pictures, believed to be originally invented in 1844 by Scottish mathematician Hugh Blackburn. This 3-pendulum rotary type of harmonograph gives a wide variety of pleasant results, and is fairly easy to build once you've settled on a design and have acquired the appropriate materials and tools. This is a great project to do with kids and can result in endless experiments creating new types of geometric designs. Skip to More Results and Movie Two lateral pendulums swing back and forth at right angles to each other with arms connecting to a pen. One moves the pen from side to side, and the second moves it from front to back on the paper.
Quadcopter build log 1. Introduction This page will be a walktrough on the creation of my quadcopter. 2. Should you decide to build your own frame, start with drawings as every engineer does. Cross (aluminium square tubes from the local DIY shop) For the Dutch, Hornbach is your next stop ;-) Lower level of the "Hamburger", with light switch, power plug, Spektrum satellite receiver and LiPo low battery warner. 3. I decided to make a 'power ring' to provide the ESC's and other equipment with power. After supplying your ESC's with power, you have to program each ESC to let it function properly for a Quadcopter. Typical programming card Quadcopter setup. 4. Before you make your control board unreachable by wiring etc, be sure it's programmed with the latest firmware. Pin 1 on the KK board is located here: The Lazyzero KK multicopter flash tool is excellent for upgrading your control board to the firmware of your liking. The control board should contract less vibrations from the motors as possible. 5. 6. !! 7. 8.
Dentsu – ASOBERU－T – New T-shirt technology – Hold up a smartphone over the T-shirt, then characters and other designs will pop up on the screen from nowhere Dentsu, a Japanese advertising company, announced that they have developed a new T-shirt technology called “ASOBERU－T”. They developed the unique and fun T-shirt technology that gives you 3 different ways to enjoy the T-shirt: Play, Shot and Share. To start playing with the T-shirt, you need to install the dedicated free application on your smartphone. Play: Hold your smartphone over the T-shirt, then you will see characters and other designs pop-up on the screen from nowhere. Shot: Pose with the characters and take some good photos with them. Share: Post those photos on the SNS sites. As part of its first stage, BEAMS, which is a popular Japanese clothing brand, is going to release 5 kinds of “ASOBERU－T” T-shirts in collaboration with Gindama (anime) and The Wonderful!
10 Ways Google Glass Will Change Us — Whether We're Ready Or Not We have not fully appreciated what "Google Glass" (Google's term for its new wearable computer) will actually mean for our future. If this product is widely used there will be fundamental and irrevocable changes coming soon to our society — sooner than we think. I can envision at least 10: 1. Some would say that Jeremy Bentham's "panopticon" is already upon us. 2. If someone can access information about a real-world object instantly by merely looking at it in front of them, consider what the advertising industry could do with this product. 3. Safety concerns are already being voiced over Google Glass. 4. As we saw following the Boston bombing, the case was broken wide open due to a commercial surveillance video. 5. Legal challenges will abound. 6. Most professionals currently go to an office and bang out reports, memoranda, or emails on a keyboard day in and day out. 7. Traditional education today is (in most places) very outdated. 8. 9. 10.
Nanobots Could Perform Surgeries in The Future Putting a robot in your eye could be the next innovation in medical technology. Researchers in Zurich are building nearly microscopic bots to help with delicate surgeries. The bot has a retractable needle for probing and a body that is only a quarter-millimeter in diameter — which is the equivalent of about 4 human hairs. This means it's as thin as a surgical scalpel and its needle is just as sharp. Given the size of the robot, any surgery could be non-invasive and minimal. The system is not yet ready for humans, though researchers did conduct a first round of experiments with the technology by exploring the eye. Image Courtesy of Youtube/03dom
DIY CNC Router Plans : How to Build NOTE: I originally posted this on my arts and crafts blog, Make It With Jason, and you're welcome to go visit and check out my other tutorials, reviews, and step by step drawing and painting lessons. Ever since I saw my first CNC, I knew I wanted to own one. I'm a realist though, and I also knew that I wouldn't own a REAL $20,000 one. So, on a whim this spring, I decided to design and build a homemade 3-axis Computer Numerical Controlled milling machine myself. I looked all over the web and decided to build one using drawer slides as my rails, an arduino as my microcontroller, and try to keep everything within the $300 mark. So far so good. So, without much ado, I am going to show you the steps I took to build my diy cnc router project (please realize, as of April 16th, 2013, this project isn't quite finished--in fact, it's at the halfway mark). Onto the Instructable!

MK3 Exoskeleton Suit Promises to Make Schoolgirls Better, Taller, Stronger Cyborgs might walk among us one day. For now, it’s just Japanese schoolgirls decked out in exoskeleton suits. You might have noticed that manufacturers turn to schoolgirls whenever they want to market some hot, new product in Japan. This time around, it’s the Powered Jacket MK3 developed by Sagawa Electronics. It’s the first commercially available exoskeleton that’s being marketed in the country. The promotion video starts out a bit weird at first, but watch for a bit longer to see the demo of the exoskeleton suit. The exoskeleton will be made available in limited numbers starting this month and will be priced at $123,000. VIA [ Dvice ]
scientists break record for thinnest light-absorber | Stanford News Release July 18, 2013 Stanford scientists have built the thinnest, most efficient absorber of visible light on record, a nanosize structure that could lead to less-costly, more efficient, solar cells. By Mark Shwartz These four wafers contain the thinnest light-absorber ever built. The absorber layer consists of billions of gold nanodots. Stanford University scientists have created the thinnest, most efficient absorber of visible light on record. "Achieving complete absorption of visible light with a minimal amount of material is highly desirable for many applications, including solar energy conversion to fuel and electricity," said Stacey Bent, a professor of chemical engineering at Stanford and a member of the research team. Thinner solar cells require less material and therefore cost less. For the study, the Stanford team created thin wafers dotted with trillions of round particles of gold. Visible spectrum Record results The results were record-setting. Final goal
