Imagine if all the windows of a building, and perhaps even all its exterior walls, could be put to use as solar collectors. Soon, you may not have to imagine it, as the Norweigan solar power company EnSol has patented a thin film solar cell technology designed to be sprayed on to just such surfaces. Unlike traditional silicon-based solar cells, the film is composed of metal nanoparticles embedded in a transparent composite matrix, and operates on a different principle. EnSol is now developing the product with help from the University of Leicester’s Department of Physics and Astronomy.

“One of the key advantages is that it is a transparent thin film that can be coated onto window glass so that windows in buildings can also become power generators,” said Chris Binns, Professor of Nanotechnology at Leicester. “Obviously some light has to be absorbed in order to generate power but the windows would just have a slight tinting (though a transmission of only 8-10% is common place for windows in the ‘sun belt’ areas of the world). Conversely the structural material of the building can also be coated with a higher degree of absorption. This could be side panels of the building itself, or even in the form of ‘clip-together’ solar roof tiles.”

Research partners are developing prototype squares of the material, measuring 16 square centimeters each. Ultimately, EnSol hopes to achieve a cell efficiency of at least 20 percent, and have its product ready for the commercial market by 2016.

This development is reminiscent of Sphelar cells – solidified silicon drop-based solar cells recently developed by Kyosemi Corporation. Although the technology is different, they are also intended to be used in solar panels that double as windows.

With iPad, home automation would be much easier system to be installed and implemented - and the price would be more affordable.

iPort has introduced two new products in its Control Mount Series for the Apple iPad and iPod touch.  The CM2000 Control Mount for iPad and the iPort CM100 Control Mount for iPod touch both integrate the handheld Apple touchscreen products in an in-wall frame, transforming them into in-wall touchscreens for display of weather, news, stocks and many other preferred Apps.

The CM100 also transforms the iPod touch into an in-wall Internet radio source, and connects to any stereo or audio/video receiver.  Users can download their choice of any Internet radio apps available in the Apple App Store and play the audio back through any connected stereo system.
The CM2000 (US$499) and CM100 ($250) may be installed in either a vertical or horizontal orientation, depending on the functionality and design of the room.  When installed into the iPort, the iPad and iPod touch remain constantly charged.

The word drone may sounds related to any contemporary sci-fi flicks, or images of attacks carried out remotely on hostile lands, or even your high-school biology teacher’s voice. We don’t expect a drone to help us save water, but that’s what Arad Metering Technologies intends to do. The Israeli company’s battery-operated drone is one of the novel tools it’s deploying to help consumers and companies conserve H₂O — and to make money.

Such an idea would come out of Israel is no coincidence. The country is poor in water and rich in tech innovation, much of it born of constant military conflict. Israel pioneered the use of unmanned aerial vehicles after it lost many fighter jets in the 1973 war. But Arad’s drones don’t fight: They read data from the company’s patented water-meter system to detect leakage or, in irrigation systems, drought.

The World Bank estimates that water wastage costs utilities $14 billion a year worldwide; in developing countries, 200 million more people could be served by the water lost to leaks and theft. Arad CEO Dan Winter says this is largely a consequence of how the business works in places where water is cheap or untaxed: “You train people to abuse water because they pay very little.”

With this innovation, instead of meter reading - it can provide real time monitoring of water supply infrastructures. Its technology can find irregularities — a pipe failure, an unusually low flow rate, or a too-constant one that could indicate a leak — in a few hours, rather than every 60 days as with a typical meter reading.

Arad’s system is built around what looks like a standard meter. The difference is on the inside, where you’ll find 3G wireless technology, a microcontroller, and 20-year batteries. Every 11 to 30 seconds, the system transmits data, which can be picked up by a drone (best for quickly covering big distances in remote areas) or by a drive-by or fixed-base reader. The data are then analyzed by computer to gauge how much water has been consumed, how much was lost, and even where tampering may have taken place. As a result, companies can save both water and man hours.

The possibilities for Arad’s services go far beyond water should be covering abilities to monitor everything from municipal infrastructure, such as traffic lights, to security-camera networks — basically any complex system prone to localized failures and waste. Arad has its own way, to proof drones could be associated with saving, not destroying; life, not death.

Some cars have tire pressure monitoring systems for a while now, but this new system from Schrader Electronics takes that useful concept into the future.

It’s not quite explained whether this wireless Talking Tire Monitoring System actually talks to you, but one way or another it notifies you when your tire pressure is low. But it’s a whole lot smarter than that, showing you how much tread is left on those tires, and even sensing slippery road conditions in real time, notifying you how much traction your tires are getting.

In other aspect, it also could help motorists significantly reduce their carbon tyreprint as vehicles with properly inflated tyres boast an improved fuel efficiency. In addition, underinflated tyres wear out quicker and need replacing more frequently.

After three years of research and one year of experience as a satellite engineer, Song Hojun has found that it is possible to launch and operate a personal satellite at a fairly reasonable price. In addition, he has for the past five years been exploring ways to integrate the concept of a personal satellite project into cultural contexts and into his artistic practice.

All the satellite-related systems (except for the rocket to launch it) are DIY programs — designed so that regular people may also have the chance of developing and eventually launching their own.

Song have presented this system and how it works at the Machine Project, Los Angeles on 2010, 25th April.

For the people who want to study or getting a clearer picture of the involving mechanisme, they can download Song’s book from Google Books here.

Roughly, at $20 to build? This 9 digit pulse counter is an excellent example of home built tools. Josh, the builder found himself repairing a device and in need of a pulse counter. With the components cheaply available, he just built his own. He says that it has a few limitations, like display brightness, but overall it seems to do the job well. All the stuffs, steps and even PCB can be downloaded from his site at your own will.

Alright, here we’re going for chapter on Manchester Encoding. Brian J Hoskins did just that when building this RC5 decoder. This protocol is widely used in television remote controls. You use them on a daily basis, don’t you think it’s time you understood what’s going on? Check out his writeup and learn the dark art of invisible light communication. Or just skip the learning and follow this how-to.

Do you have any idea on how easy it is to build your own RFID reader? Well, we stumbled upon some sites that’ll give you some clearer picture on how to make this thing happens. As pointed out by hackaday,

[Klulukasz] left a comment pointing to this DIY RFID reader that was a final project in 2006 for a class at Cornell University. It is well documented and includes not only a schematic and code, but an explanation of the design considerations used during the build. The project uses an ATmega32 and the parts list priced out at about $50 at the time. There were plenty of responses to theRFID spoofer post pointing out that there are readers available for $40, but we want the fun of building our own.

A bit more vague with the details but no less interesting is this other simple RFID reader design.

This sounds like a sci-fi movie, instead - they use tomatoes other than humans! Thank god, we’re safe! We all know tomatoes pack a powerful acidic punch, but we never thought we’d see one lighting up a room! Cygalle Shapiro of Israel-based d-VISION has created an incredible LED lamp that is completely powered by real, edible tomatoes. Currently exhibited at the Milan Furniture Fair, the design collects energy from a chemical reaction between tomato acids, zinc, and copper. This design doesn’t only explore advances in lighting technology – its also an art piece that sends clear and powerful social-conscience messages about where and how we receive energy.

To some crowds, irrigating a small garden is a relatively relaxing and sometimes therapeutic activity, well if you are a botany/biology nerd or desperately really need a hobby - but going away for any length of time can present a problem. The simple solution of course is to purchase a hose-bib/timer package from Home Depot for about $30 and set up a small drip system to efficiently water each plant or row of plants (rather than a wasteful sprinkler system). Going along with conserving water is using a rain barrel collection system to capture rain for later use thus eliminating or more likely reducing treated water consumption.

Adding a rain barrel complicates the system significantly as there isn’t much water pressure at its spigot compared to a standard city spigot which has somewhere around 40 psi. Also, if the barrel is empty, you don’t want your plants to die and thus you need to be able to detect that the barrel is empty and switch to city water.
