Lego-Like Chemistry and Biology Erector Set. Gallactronics: How to Make Oil From Plastic (theory) Among the many irremediable wounds that man is inflicting upon the environment, the improper disposal of waste plastic is growing into an alarming issue of concern.
Despite its amazing properties of strength, durability and its light weight, plastics have a major drawback: they can take up to 500-1000 years to naturally degrade. So if plastic had been discovered 500 years ago, and if Shakespeare used to brush his teeth, then his toothbrush would still be lying somewhere in England! Some other issues with waste plastic are that it affects humans, animals and marine life; it causes soil infertility where dumped; and only 8% of all plastic waste is recycled! Sounds a trifle, right! Another lesser known factual reality is that for the production of plastic, 7% of the global crude oil is consumed, which is more than China's total crude oil consumption. Le Hackacon - 29 octobre 2016. Pièces détachées électroménager : tous les sites. These DIY Eco-Friendly "Air Conditioners" Are Cooling Down Bangladesh. Out in the sticks of Bangladesh, the threat of flooding means that 70 percent of the population live in corrugated tin huts, most of which aren’t hooked up to an electricity supply.
In the heat of the summer, this can practically turn these houses into ovens. This $99 Gadget Turns Your Smartphone Into A 3D Printer. 3D printers have been set for big things for a long time.
But as rapid as their recent boost in popularity has been, they’re pretty clunky machines and generally not on the cheap side. However, a San Francisco-based startup has plans to release a 3D printer for your smartphone, all for under $100. OLO is being launched through a Kickstarter campaign, which has already smashed its $80,000 target eight times over with a total of more than $650,000 raised. The OLO 3D printer allows users to create three-dimensional prints using the light from their smartphone screen. You can choose your choice of design from an existing 3D design platform that is compatible with the OLO app. Check out the video at the bottom for more of an insight into how the printer works.

Here's How to Build a Home-Made Electric MotorVideo. Fully 3D Printed Working Engine Runs Completely on Hot and Cold Water — and You Can Print Your Own For Free. 3D printing is fascinating, especially to those individuals who have not ever seen the technology in action previously.
However, like with all new technology, this fascination subsides as time goes on and the technology becomes more commonplace. Perhaps we aren’t quite at this point yet with 3D printing, but the intrigue generated through the seeing, touching, and feeling of 3D printed objects will surely wither with time. One man in New Zealand, named Don Clucas, realizes this, and with the help of the University of Canterbury, he has come up with a way to fascinate even those already acclimated to 3D printing technology.
In a project that could be considered “breathtaking,” “innovative,” and “potentially revolutionary,” Clucas has created what he believes is the first ever fully 3D printed working engine. Better yet, it runs on thermodynamics, meaning all it requires for fuel is simple tap water. Turn your Smartphone into a 3D Hologram. Ma maison sur-mesure - Site de tinyhouse-baluchon ! Pourquoi j'ai monté ma boîte. Indiegogo. SATW_INFO_2-15_DIY-Bio_FR.pdf. Electronic Interfaces: Bridging the Physical and Digital Worlds. EE40LX teaches the fundamentals of engineering electronic interfaces between the physical world and digital devices.
Students can expect to cover the material of a traditional first circuits course with a project-based approach. We start with essential theory and develop an understanding of the building blocks of electronics as we analyze, design, and build different parts of a robot from scratch around a microcontroller. This course uses the Texas Instruments MSP430G2 LaunchPad, but you are welcome to bring whichever development board or microcontroller you like!
Useful mathematics will be discussed where appropriate, but only a working knowledge of high school algebra is required to follow along for most of the course. The philosophy of the course is to learn by doing, so every lecture features a substantial lab component. Additionally, a kit of electronic components will be available from Newark element14 starting June 12. How DIY neuroscience kits put research in the hands of the curious. Greg Gage left a career in engineering when he realized his real passion was for neuroscience.
He creates kits to help spark this interest in kids, so they don’t “miss their calling like I did.” Many of the kits involve experiments with roaches. Bricole It Yourself spécial canicule: fabriquer une clim en 15 minutes. Un ventilateur, c’est bien.
Mais il faut être synchro. © DR. Loading... This tiny device creates a 3D map showing where your Wi-Fi sucks. The image above is not a computer rendering of the inside of an ant nest, but is instead a 3D map showing the strength of a Wi-Fi network at different points in a location.
Using a Wi-Fi module, an LED, and a small battery pack, YouTube user CNLohr built a device that can measure the strength of a Wi-Fi network signal in all three dimensions and render out a color-coded map to show you where that network is strongest and weakest. Here's what his device looks like: A handheld gadget to map Wi-Fi networks in 3-D space.

Arduino Vs. Raspberry Pi: Which Is The Right DIY Platform For You? If you’re at all familiar with do-it-yourself (DIY) electronics, you’ve probably heard about the comparable merits of Arduino and Raspberry Pi.
You may have even, like I did, assumed they were competing hardware platforms solving similar problems. Actually, Arduino and Raspberry Pi are quite different. Thomas Thwaites: How I built a toaster. James Bond-Style Laser Watch Finally Invented. Aquaponie. Un article de Wikipédia, l'encyclopédie libre. Système d'aquaponie réduit L'aquaponie est la culture de végétaux en « symbiose » avec l'élevage de poissons. Ce mode de culture a été utilisé depuis une haute Antiquité, notamment en Mésoamérique. Ce sont les déjections des poissons qui servent d'engrais pour le végétal cultivé.
Le mot aquaponie, traduction de l’anglais aquaponics, est un mot-valise formé par la fusion des mots aquaculture (élevage de poissons ou autres organismes aquatiques) et hydroponique (culture des plantes par de l'eau enrichie en matières minérales). Fonctionnement[modifier | modifier le code] Comment faire des graffitis en mousse: 6 étapes.
Édité par WikiHow Traduction, Team FR Les graffiti en mousse, aussi appelés « écograffitis » ou « graffitis verts » remplacent la peinture en bombe, les marqueurs et autres substances chimiques généralement utilisées pour graffer. Ils utilisent à la place un pinceau normal et de la mousse qui pousse toute seule sur les murs. Avec la montée des produits bios et écologiques, le graffiti a donc su séduire les artistes militants de tous bords.

Deshawn Henry, a Civil Engineering sophomore at the University of Buffalo, spent his summer developing a solar lens using inexpensive supplies from a hardware store that can clean 99.9% of pathogens in a liter of water in about an hour.
The research project is practical and inexpensive, with the potential to be widely implemented and save lives. Over one billion people around the world lack consistent access to clean water, leading to the death of a child under the age of 5 every single minute. Many water treatment options are expensive. Maker Faire, l’événement fondateur du do it yourself. Homemade Magneto Shoes Let This X-Men Fan Walk On The Ceiling. Make Your Own Droplet Microscope Lens for a Penny. Clear liquid droplets can bend light, acting like a lens. By exploiting this well-known phenomenon, scientists have devised a cheap and simple way to turn a smartphone into a high-resolution microscope.
The high-powered lenses cost less than a cent apiece to make, and all you need is a cover slip or glass slide, some common polymer, and an oven. The method would be immensely helpful for diagnosing medical conditions in remote areas and developing countries. Conventional lenses are usually made in one of two ways. DIY sites.
