The Making of Arduino For Banzi, this is perhaps the most important impact of Arduino: the democratization of engineering. "Fifty years ago, to write software you needed people in white aprons who knew everything about vacuum tubes. Now, even my mom can program," Banzi says. "We’ve enabled a lot of people to create products themselves." Not all engineers love Arduino. To fuel greater adoption of Arduino, the team is exploring how to integrate it more deeply into the education system, from grade schools to colleges. But spreading the Arduino gospel is only part of the challenge. Arduino has also created its own cottage industry for DIY electronics. Because the team can’t afford to stock hundreds of thousands of boards, they instead produce anywhere from 100 to 3000 per day at a manufacturing facility near Ivrea. The Arduino team is now earning enough to support two of its members as full-time employees and is making plans to bring even more circuit board power to the people.
Maker Education Initiative | Every Child a Maker Smart Materials Welcome to this interactive handbook on Smart materials for designers, it should be your key to many new and exciting products that will be possible only if you use Smart materials. Using a simple table at the bottom of this page, explore the options. However, you are probably wondering what are Smart materials, how do they work and what can I do with them? Take a look round and let your imagination runs free over the possibilities. What are smart materials? This sounds a simple question but is not that easy to answer beyond the obvious, and really not too helpful statement "a material that displays smart behaviour". Smart behaviour occurs when a material can sense a stimulus from its environment and react to it in a useful, reliable, reproducible and usually reversible manner. SMART materials in Products To further explain, an example material from familiar items would help. How to use this guide? Explanation of Traffic light System The information appear in a new window each time.
The Fakeproject Corporation of America Presents: A Cheap, Easy, and Scandinavian WiFi Antenna. HI INTERNETS! This page is about something I did in Moscow in 2006. I answered many questions about the project (including "IS IT REAL OMG") here. I just moved to Moscow, to a nice flat in the center. So, I decided to take matters into my own hands. Costs: Electrical tape, 9 Rubles. According to my measurements, the "Soare" napkin ring is capable of a 5-7dB signal boost, when the ceramic antenna element of the WiFi adapter is placed at the focal point. After some further testing, I found that removing the plastic casing of the WiFi adapter gave an additional signal boost (and made it easier to place the antenna). I'm uploading from this apparatus now, hunched over my laptop in my kitchen. Daniel Reetz.
Bubble Machine These are the tools and materials that I used for my bubble machine. Yours will differ greatly depending on what you have available. This is a great project to do with scraps, and odds and ends all hacked together. It doesn't have to look amazing to be a lot of fun, it just has to work. To make it easier for others to reproduce this, I've done away with my normal format of exactly what to use and instead broken it down into the five main components the machine's made from. Trough: To hold the bubble solution. Bubble Ring: A ring of holes that will spin slowly through the trough picking up the bubble solution. Motion: A slowly moving motor to spin the bubble ring. Blower: Something with a bit of puff. Power: A power source or two for the blower and spinner. You'll also need nuts, bolts, hot glue or superglue to hold everything together. The files I used for laser cutting are included in this step.
openMaterials Top 10 Things You Can Upgrade with a Little Electronics Hacking it is a skill to do a good solder joint, it comes with LOTS of practice. so most people who rarely do it will ever get good at it. Bingo. Of course, part of the issue is having a soldering iron at the right temp with a properly tinned tip. Newbies aren't using soldering stations but a cheap iron they got at rat shack (You have questions? I don't expect to ever master tricky stuff like smts or even multilayer pcbs so I'm not much better then a newbie, anyway - and I totally suck at sweating pipe joints. Ah, well... SMT is actually a bit better than through-hole once you get the hang of it.
Apple’s Middle finger: It’s Pointed at You Let’s get this clear right off the start: Apple makes some absolutely fantastic products. The issue is not with the quality of their products, but the attitude and manner in which the company operates. They are giving their customers the middle finger, and for some reason the customers are thanking them for it. I make the argument that it doesn’t have to be this way. Apple makes luxury products.

How to Convert a Computer ATX Power Supply to a Lab Power Supply Edit Article Edited by Abizarl, Krystle C., Jack Herrick, Vertent and 42 others Computer power supplies cost around US$30, but lab power supplies can run you $100 or more! On most power supply units (PSUs), the other lines are unregulated. Ad Steps 1Look online or at your local computer store for an ATX computer power supply, or dismantle an old computer and remove the power supply from the case.Ad 2Unplug the power cable from the power supply and turn off the switch on the back (if there is one). 13 Plug the power cable into the back of the power supply and into an AC socket. Tips You can use your power supply 12V output as a car battery charger! Warnings If you suspect the power supply is damaged, do not use it!
antenna basics Antennas, to quote a friend, are one of life's eternal mysteries. "All I'm totally certain of is that any antenna is better than no antenna and the antenna should preferably erected as high and be as long as is possible or desirable". Here we will discuss the very basics of antennas including the the amazing terminated tilted folded dipole antenna. LAST MODIFIED: Sunday, 23-Jun-2013 12:55:29 PDT Please don't forget to bookmark this valuable electronics tutorial site! Authored by Ian C. Find us on Google+ What are the basics of antennas? Antennas, to quote a friend, are one of life's eternal mysteries. The basic antenna The most basic antenna is called "a quarter wave vertical", it is a quarter wavelength long and is a vertical radiator. This type of antenna relies upon an "artificial ground" of either drooping radials or a car body to act as ground. Antenna Polarisation Depending upon how the antenna is orientated physically determines it's polarisation. Antenna Impedance The Yagi antenna
Free-Energy Devices, zero-point energy, and water as fuel Hard Disk Drive Magnets For Wind Turbines Obtain super strong magnets from old hard disk drives to use in wind turbine alternators home > windThe most expensive parts of a wind turbinealternator are the magnets and the enamelled magnet wire. In a previous article we have introduced cheap and easy to make PVC wind turbine blades. Here you will learn how to obtain magnets for free and put them to good use in a wind turbine generator. Hard Disk Drive Magnets 50% of the world's neodymium magnets are currently used in computer hard disk drives (HDD) with each HDD typically containing two magnets. Extracting the magnets from an old hard drive is very easy - usually just a small selection of screwdrivers is required. This can be difficult - the easiest way is to put one corner of the backing plate into a bench vice and bend the other corner of the plate using a pair of vice grips. Neodmium Magnets in Hard Disk Drives The magnets used in hard disk drives are very strong neodymium (rare earth) magnets. Comment on this Article wind
