Every time, when we’re watching the spy movies, such as the James Bond or Mission Impossible series, you have the chance to see many different types of tiny gadgets, where most of them were very cool!
In this case, many people would like to know the way to build the gadgets by themselves. Well, your search is ending here, as we’re going to develop the amazing “iButton”.
Firstly, what is an iButton? Honestly, it’s a computer chip enclosed in a 16mm thick stainless steel can. It has a unique yet durable container, which is allowing the user carrying it and travel to anywhere they want to go.
Basically, the steel iButton can be mounted virtually, as it is tough to withstand harsh environment, indoors or outdoors. Plus, it’s small and portable size making it easier for the user to attach it to a key fob, ring, watch and other items.
It’s incredibly easy to get information into and out of the iButton. All you have to do is simply touch your iButton to a Blue Dot receptor or the iButton probe and connects it to a PC. The Blue Dot receptor is cabled to a 1-Wire adapter, which is attached to a spare PC port.
Believe it or not, you can build an iButton with less than $50. After it, you might use it to store electronic cash, gain access control to buildings or computers, asset management and various data logging tasks without any hassle.
Most of the computers in nowadays, are incredibly slow, if it compares with the super-fast computers, which are using light to process large amounts of data!
For your information, the Engineering and Physical Sciences Research Council (EPSRC) is supplying the fund to two universities to establish a world-leading research programme on the fundamental science, which is known as “nanoplasmonic devices”.
Believe it or not, this research is considered as one of the costly research, as it is a £6 million research programme located at Queen’s University Belfast and Imperial College London. The project has been dated to launch on September 1, 2009.
Talking about nanoplasmonic devices, they’re a very tiny nanoscale metal structures. Honestly, it’s 100 times smaller than the width of a human hair and has the ability to guide or direct light!
The main objective of the project is to develop the super-computers that using light signals, instead of the electric currents used by today’s computers. For making it becomes a reality, the researchers are now building a raft of new metallic devices, including tiny nanoscale sources of light, nanoscale ‘waveguides’ to guide light along a desired route, and nanoscale detectors to pick up the light signals!
With the above advanced technology, the era of “Super-computers” is going to be arrived very soon… http://www.qub.ac.uk
Try to imagine, what’s the feeling, if you have a robot inside your home, which is able to perform multiple tasks in daily life? It sounds like a very cool robot to you, isn’t it?
Whether you’re notice it or not, many household in the United States and Japan have been using robot to help them doing some simple task, such as the Roomba vacuum that normally being used to clean up the dirt inside the house. Honestly, the Roomba vacuum is considered as one of the best iRobot vacuum in many households in U.S.!
As you see, this Personal Robot 2, which is also known as, “PR2” is an intelligent two-armed mobile robot that well-designed for mobile manipulation research and applications. PR2 has the size of a human and have the ability to perform tasks in everyday environments. Continue reading
We always seem in the movies, where there are some sorts of tiny robots that being used to kill the enemy, by simply a sting on the enemy’s body! If you think it’s only a science fiction, then you should read on this article…
Recently, a group of scientists from Israel’s Technion University has invented a tiny robot. The robot is made by using Micro-Electro-Mechanical Systems (MEMS) technology.
The robot is known as the tiniest robot in the world, which is able to crawl through a person’s vein to diagnose and treat artery blockage or cancer! The size of the little robot, with only a diameter of about one millimeter, didn’t has any engine or onboard controls inside it.
According to the scientists, the tiny robot is has the ability to withstand massive blood flow and push forward regardless of the magnetic field actuation direction.
The tiny robot can move up to nine millimeters a second, which is controlled by varying external magnetic field frequencies.
The research team described that they’re looking at putting the ant-link creature to work in urban water distribution systems or seek for any leaks that need repairing instantly! [link]
Life in nowadays, especially for the people who busy with their daily job can be tough. Go figure, after a long day of work, most of them are exhausted. Isn’t it better to have a dorm door, which can be automatically open, every time you back to home?
In this case, the iDoor would be your ideal solution here. For your information, the iDoor is outfitted with an iPhone controlled hydraulic door opener and unlocker.
In order to use the iDoor, you have to tap the iDoor app on your phone’s home screen, and the door opens for you, once you’re standing in front of the door!
The iDoor is fully-controlled directly from a scrounged up PIII computer running Ubuntu, which is interfaced with the hardware using the Phidget 8//8/8 control board. The full PC is the right choice, mainly for internet connectivity and development speed. The software part was well-written in Java using the Phidget library.
Technically, the door is controlled by a hydraulic actuator, which is tapped into the sink in the room. Two of the taps (Sink inflow tap and outflow tap) are connected to a set of four one-way solenoid valves. In addition, there are two relays between two pairs of solenoids and the 24v power supply. One relay is for opening the door, while the other one is closing it!
iDoor is a very interesting project, come and build an iDoor at your home!
