Gallery: Using design to build a community Architect Diébédo Francis Kéré (TED Talk: How to build with clay … and community) designs with both people and sustainability in mind. Raised in Burkina Faso, though he’s now based in Berlin, Kéré is always keen to include community-oriented spaces that invite people to sit down and engage in thoughtful conversation. The central nature of community is a concept he has borrowed from Burkinabe tradition, and it’s one that plays a fundamental role in his design thinking. His architecture is pragmatic yet quietly playful, driven by a desire to make the most of (sometimes minimal) local resources. So what does he think makes a great community space? Timelapse TIME and Space | By Jeffrey Kluger Spacecraft and telescopes are not built by people interested in what’s going on at home. Rockets fly in one direction: up. Telescopes point in one direction: out. Of all the cosmic bodies studied in the long history of astronomy and space travel, the one that got the least attention was the one that ought to matter most to us—Earth.
teen tech camp recap As some of you may already know, last week I had the honor and privilege to help organize the 2013 Teen Tech Camp in Durham, North Carolina. The event was extremely challenging, fun and one of the most rewarding things I have ever been a part of. the idea Antikythera Mechanism Simulation These simulations were written in C++ as a senior year project by Fivos Asimakopoulos (email: fivasim at gmail.com) These versions are preliminary ones, without much attention to the relative gear diameters or vertical positions. However, the teeth count of the gears and the operation are accurate. Again, as for the animations, there are two versions of the simulation: one according to Price, and one according to the recent findings of the Antikythera Mechanism Research Project. The only inaccuracy of the new version is the fact that gears K1-K2 are fixed and they do not rotate along with gear E4.
Animal Parade A database containing examples and information is not always enough. Who would not love to feel and smell the wood too? For this purpose, we introduce FSC® Animal Parade – a series of three animals made from 36 lesser-known timber species kindly donated by partnering companies. In the accompanying book you will find specifications and real-life wood samples. Each piece of wood has a number carved into it, which guides you to a page containing technical information, pictures and a brief description of that species.
Intelligent watering system with arduino... In this instructable i wanted to share my automatic irrigation system using arduino, soil humidity sensor and a simple aquarium valve attached to a servo... Humidity sensor takes constant readings of the soil moisture and transfers to Arduino which controls a mini servo attached to a tiny valve. you can tell the system amount of moisture needed simply turning the potentiometer... then the system opens and closes the water valve if the soil is below your specified level of moisture... Parts needed: - Soil humidity sensor ( dealextreme $3) - Arduino of any kind (dealextreme $10) - mini servo of any kind ( 9gm ~$5) - aquarium valve - 10K potentiometer - water pipe (thin aquarium type) First dip the fork of the humidity sensor to soil completely... connect sensor to A0 and 10K pot to A1 pins of Arduino. connect servo to D9 pin. power up the system with anything you like... (Wall adapter or battery )...
Hublot painstakingly recreates a mysterious, 2,100-year-old clockwork relic - but why? Why on Earth would you want to strap one of these to your wrist? It barely tells the time, and it can't take pictures, tweet or connect to your Facebook. In fact, very few people would have the faintest idea what it is, or why you'd want one at all. Digital/Analog Clock - Arduino + PaperCraft In this instructable we will be recreating a clock inspired by Alvin Aronson's original design. When I first saw this clock I was very impressed by how clean an elegant the design was I immediately wanted to recreate this effect. Alvin Aronson's original design (made with corian and wood): I hope some of you feel the same and use this as a guide to be one-step closer to having one of your own Essentially, we have a seven segment clock where instead of LED's we have digits moving in and out of the pane, the shadow created by these digits will allow the user to read the time against the white on white digits.
Battery Life in Gadgets - The Science of Battery Life in Electronics The proof, to me, was irrefutable. I had bought a new iPod within weeks of my coworker: the same generation player, running on the same lithium-ion (li-ion) cobalt oxide battery. She plugged it into her computer every day to get to her music. That seemed like an astonishing mistake—obviously, her iPod's battery would suffer, since it would cycle every day, multiple times during each 8, 10 or 12-hour workday. My player, which I ran down completely before each charge, would burn less cycles, and retain more power in the long run. A year later, her iPod could barely squeak through a subway ride from Brooklyn to Midtown Manhattan. Interactive Ear tool showing how the ear works by Amplifon The ear is the organ which controls hearing and balance, allowing us to understand our surroundings and position ourselves correctly. It is split into three parts: outer, middle and inner. This guide will take you through each part of the ear in turn, answering those essential questions – what are the parts, what do they do, and how? Pinna Helix Antihelix
