CNC Panel Joinery Notebook I’ve been collecting clever ways of slotting flat stock together since I first read Nomadic Furniture back in 1999, well before the advent of the accessible hobby-class CNC tools that today make manufacturing parts like these pretty easy. Now, the world is full of people designing models, project enclosures, sculpture, furniture, and all kinds of other cool stuff to be assembled from parts made on laser cutters and CNC routers. I keep expecting a definitive book or website to emerge that covers the “bag of tricks” in an organized way, but so far, I haven’t found it. Maybe this article can serve as a jumping-off point. In any case, I think it’s time to share my notebook of CNC panel joinery. In presenting this material, I want to first acknowledge my respect for the world’s established and ancient traditions of joinery. I may abuse some terms, without meaning to, and I am glad to be corrected by those who are in the know about traditional joinery. Laser vs. Biasing Cross (“X”) Joints
Introducing The Phlatprinter * Available for Purchase * Phlatprinter - From Sketchup to the real world Hello, first off Richard, You have to love your job! I really don't know where I went off track with my career but designing and building machines is really a passion I have. the other machines I have plans for are A vacuum former with a 2'x2' area. Energy Efficiency in Thermal Comfort- Passive Air Flow Principles Energy efficiency in design is ensuring that the usage of energy in your building has been optimized to ensure that it is not wasteful or uncontrolled, but rather well regulated and made sustainable. The implications of energy efficient design are realized at the point whereby huge savings are made in the built environment simply because of the simple energy saving measures that have been put in place. energy efficient airflow through an atrium Many buildings in the developed world have been designed with strong emphasis on maximizing on views and optimizing on space use. The current reliance on artificial systems is not energy efficient design. However an intrinsic weakness of this model is its reliance on energy to ensure it works as required. Air flow within the building serves two purposes, namely provision of clean fresh air for occupants to breathe and assisting to regulate temperature and maintain it at comfortable levels. Energy Efficient Ventilation – The Chimney Effect General
Calculadora en línea Simbólico y Solver Education Theory/Constructivism and Social Constructivism - UCD - CTAG "Constructivism is the philosophical and scientific position that knowledge arises through a process of active construction."(Mascolol & Fischer, 2005) "As long as there were people asking each other questions, we have had constructivist classrooms. Constructivism, the study of learning, is about how we all make sense of our world, and that really hasn’t changed."(Brooks, 1999) Background Constructivism and Social Constructivism are two similar learning theories which share a large number of underlying assumptions, and an interpretive epistemological position. Underlying Assumptions Jonassen (1994) proposed that there are eight characteristics that underline the constructivist learning environments and are applicable to both perspectives: Constructivist learning environments provide multiple representations of reality. Epistemology The default epistemology in education is an empirical/reductionist approach to teaching and learning. Main Theorists Dewey Piaget Bruner Vygotsky According to Vygotsky:
4.5-Billion-Year-Old Antarctic Meteorite Yields New Mineral | NASA Research | Meteorites & Early Solar System A meteorite discovered in Antarctica in 1969 has just divulged a modern secret: a new mineral, now called Wassonite. The new mineral found in the 4.5-billion-year-old meteorite was tiny — less than one-hundredth as wide as a human hair. Still, that was enough to excite the researchers who announced the discovery Tuesday (April 5). [Image of new mineral] "Wassonite is a mineral formed from only two elements, sulfur and titanium, yet it possesses a unique crystal structure that has not been previously observed in nature," NASA space scientist Keiko Nakamura-Messenger said in a statement. The mineral's name, approved by the International Mineralogical Association, honors John T. Grains of Wassonite were analyzed from the meteorite that has been officially designated Yamato 691 enstatite chondrite. Yamato 691 likely originated from an asteroid orbiting between Mars and Jupiter. When meteors hit the ground they are called meteorites.
2007 November Archive for November, 2007 071117_Aperiodic_Series003_Gazebo PAVILION – Free-standing structure (ie wikipedia)Pavilion may refer to a free-standing structure sited a short distance from a main residence, whose architecture makes it an object of pleasure. POWERS OF TEN (ie wikipedia)Powers of Ten is a 1977 short documentary film written and directed by Charles Eames and his wife, Ray. The film begins with an aerial image of a man reclining on a blanket; the view is that of one metre across. AA PAVILION “the powers of ten”The different renders of that post are extracted from theverymany proposal for the AA Ten pavilion competition. Theverymany is now developping further its proposal -currently pushing with its aperiodic series- and is looking for sponsors and eventual venues to construct it – anyone interested? 071117_Aperiodic_Series002 The flower is said to be the most conspicuous part of the plant. 071107_Aperiodic_Series001
Calculadora de Porcentajes A percentage is also a way to express the relation between two numbers as a fraction of 100. In other words, the percentage tells us how one number relates to another. If we know that number A is 25% of number B, we know that A to B is like 25 is to 100, or, after one more transformation, like 1 to 4, i.e., A is four times smaller than B. This is what the percentage calculator teaches; what is a percentage and how to find a percentage of two numbers. It is essential and practical knowledge. How to find a percentage of something? At first, let's start with the most straightforward example with 100 cookies. Let's go with something a bit harder and four times more delicious: 400 cookies! Now, something even harder - 250 cookies. So what is percentage good for? What about decimal fractions and percentages? Percentages are sometimes better at expressing various quantities than decimal fractions in chemistry or physics. How to find a percentage of something? So what is percentage good for?
Shelter Shelter - Building Systems A catalog of non-toxic building systems. Monday, June 12, 2006 EcoNest - Creating Sustainable Sancuaries of Clay, Straw, and Timber This recent book by Paula Baker-Laporte and Robert Laporte details these architects' current focus of work, the 'EcoNest' sustainable and non-toxic cottage based on their revival and improvement of the clay, straw, and post & beam 'wattle and daub' construction techniques common to traditional archiecture of Europe and Japan. With EcoNest the Laportes present a detailed and lavishly photographed introduction to a method of construction and style of design that are not only sustainable and non-toxic but also exceptionally graceful and comforting in its organic aesthetic. Unfortunately, those looking to this book for a detailed system of instructions for this clay and straw building technique and the design of homes based on it will be disappointed.

Afritecture: Exploring Africa's influence on contemporary architecture - Afri-love Afritecture aims to celebrate the African influence on today's built environment. Africa's influence on modern art and music is well documented but African architecture is rarely considered with reference to contemporary architecture. "Over the centuries, cultures within continental Africa have developed and used numerous design principles in the design and construction of their surroundings. Out of necessity, availability, and creativity, these aesthetics - which are as varied as the continent’s vast cultural diversity, and further modified as they have passed through the screens of Eastern and Western cultures - are still prevalant within today’s urban context not only in Africa, but throughout the world."
