Building a Celtic Roundhouse The walls of roundhouses were either dry stone filled in with clay and straw, or a ring of support poles weaved with wattling and plastered in daub, or a mixture of both stone and wattling as being built here (left). Wattle and daub is one of the oldest building techniques dating back to the Bronze Age and beyond. Wattling is a way to build walls by weaving long flexible sticks in and out of upright posts. Hazel, which is pliable and grows naturally long, is a good species to use for wattle. It is also the preferred wood used by straw bale builders to pin bales together.
The Desire for Learning I love learning and hope that if you don’t that I can convince you to love it too. I never stopped learning after college, in fact my learning increased. My raw, unquenched, and enduring thirst for learning and knowledge seems to be limited only by physical weaknesses. Online Computer Science Courses In its purest form, computer science is the research and development of technology that solves specific problems. Computer science has brought the world smart phones, GPS systems, the gaming industry and tablet computing, along with technological developments that assist government, industry and medicine. In addition to creating new technology, computer scientists also make improvements to existing technology and study the ways computers can make our lives easier.

The Ecocapsule “is suitable for a wide range of applications,” write the designers, such as an “independent research station or a tourist lodge to an emergency housing or a humanitarian-action unit.” Those interested in buying one will be able to pre-order at the end of 2015, with delivery in the first half of 2016. A display unit will be show during the Pioneers festival in Vienna on the 28th-29th of May.
50 Awesome Search Engines Every Librarian Should Know About by Staff Writers Students, teachers and the public turn to their librarians for help researching everything from technology to genealogy to homework help and lesson plans. Even if your library is equipped with subscriptions and memberships to top of the line databases and online journals, you’ve probably had to get creative during a patron’s requested search for something unfamiliar. Secret-Knock Gumball Machine One of the best things about exhibiting at Maker Faire is giving attendees a challenge. For the 2010 Maker Faire Bay Area, I decided to combine a past project of mine, a door lock that opens only when you give a secret knock, with a standard crowd pleaser: candy. The result was this Secret-Knock Gumball Machine, which tempted and tested the crowds at Maker Faire to guess the right rhythm and receive a treat.
How Whole Turmeric Heals The Damaged Brain Long considered impossible to accomplish, new research reveals how a simple spice might contribute to the regeneration of the damaged brain. Turmeric is hands down one of the, if not the, most versatile healing spice in the world with over 600 experimentally confirmed health benefits, and an ancient history filled with deep reverence for its seemingly compassionate power to alleviate human suffering. But, most of the focus over the past decade has been centered on only one of its many hundreds of phytocompounds: namely, the primary polyphenol in turmeric known as curcumin which gives the spice its richly golden hue.

Charlieplexing LEDs with an AVR ATmega328 (or Arduino) Charlieplexing is an ingenius method for controlling many LEDs without using many microcontroller pins. You can turn on or off one LED at a time. To light more than one LED at a time, you can scan the LEDs by turning a sequence of them on and off really fast. The number of LEDs you can control is determined by this formula: N pins * (N pins – 1). For example, if you have 4 pins, you can control 12 LEDs (4 pins * 3 pins).
