If The God of Technology Made A Wish-List for New Year..


This is what it would look like. These innovations not just demonstrate brilliance in science and technology but also a social spin and street-smart attitude
Innovations of a year are worth watching not because they speak of the year gone by, but because they indicate what is in store in the coming year. That is what we had in mind when we chose this set of marvellous innovations from year 2012, which range from motion-activated screwdrivers and 3D printers to social hearing-aids and self-regulating tyres. These innovations demonstrate not just brain power but also street-smart attitude—and they promise to fulfil long harboured desires of not just high-end consumers and techies but common people as well.
World’s first motion-activated screwdriver
Black & Decker has used simple electronics to create a niche product. The 4V Max Gyro is a rechargeable motion-sensing screwdriver that can be controlled by your wrist movement. The device senses the movement of your wrists and uses that as a clue to adjust direction and speed of drilling. You need to rotate your wrist just one quarter turn to the right for forward, or left for reverse.

Inside: Its Invense ISZ-650 Z-axis integrated micro-electromechanical-system (MEMS) gyroscope designed for high performance, robustness and high shock resistance. MEMS technology makes it small enough for a compact screwdriver. Light-emitting diode (LED) lights are used to illuminate the workspace; plus an effective lithium-ion battery ensures that the device remains charged for as long as one-and-a-half year.
A factory in your garage
The MakerBot Replicator 2 is a compact desktop device that lets you print 3D objects. It works using Fused Filament Fabrication (FFF) technology. Basically, it melts plastic and squeezes it through an extruder to build an object layer-by-layer. Replicator 2 uses polylactide filament—a super-strong renewable plastic that can be used to make even movable parts and complex assemblies. The device allows print dimensions of 28.5×15.3×15.5 cm3, with a  path-breaking 100-micron resolution ensuring smooth  surfaces and fine features.

Inside: It uses modified version of Mighty Board—  MakerBot’s original 3D printer control technology—that can control up to five stepper motors with BotStep stepper controllers, two extruders (with heater cartridges, safety thermostats, thermocouples and fans), Replicator interface board and heated build platform, apart from connecting up to six end-stops. The extruder is nearly identical to the original Replicator extruder with minor tweaks to optimise manufacturing of injection moulded parts. Other features include 3-point levelling system and 32 per cent lower power consumption.

While the original Replicator design was completely open, there is a lot of furore about the company moving to a closed model now. However, the founder claims that the core technology comprising the extruder and the control board are still open. Original component information is available at http://www.makerbot.com/blog/tag/mightyboard
Translating sign language into speech
Not everybody can understand sign language – this is a practical difficulty that hearing and speech impaired people face everyday. Four students from Ukraine have developed a simple and inexpensive solution called Enable Talk comprising special gloves and a mobile application, which can detect signs made by the user wearing the gloves, and convert these into text or speech on the phone. Working on the user feedback, they are now enhancing the system to also track arm movement in addition to just fingered signs.

Inside: Eleven flex sensors and eight touch sensors embedded in the glove convert movement into proportionate electrical resistance. The glove also includes 3D digital linear acceleration sensor, magnetic sensor, accelerometer and gyroscope. An Atmel XMEGA A3 microcontroller processes analogue signals from sensors and transmits the resulting data to a mobile using Class 2 Bluetooth module (BlueCore4-Exteanl chipset from Cambridge Silicon Radio). The glove is powered by a 750mAh lithium-polymer accumulator, which can be charged through USB or built-in solar battery.

Easy and intelligent LED bulbs
You can control these light-emitting diode (LED) bulbs with your mobile phone – and no, we are not talking of complex building-wide lighting solutions. iLumi is a simple LED-based bulb that can be screwed into any common socket. It is available in small, large, white and full-spectrum models, which are supposedly super energy-efficient, last up to 20 years, and can be controlled with a simple mobile application. You can schedule the light, alter its brightness of hue, motion-activate it, and do much more. Founders Corey Egan and Swapnil Bora are waiting to finalise the design and manufacture the bulbs, which have already won numerous awards.

Inside: iLumi’s HyperLux technology allows it to be programmed to display millions of colours and makes it one of the brightest bulbs around. The bulb, which is compatible with normal sockets and power supply, includes Bluetooth, 16-bit, 256kB flash processor, additional 4-megabit flash memory, real-time lighting control for up to 100 iLumi bulbs, and clock with battery back-up. The control application is simple and intuitive, and can be downloaded and run on Android and iOS devices. The company plans to include a software developer kit (SDK), to come up with innovative ways for programming and controlling the bulb.
Tyres that pump themselves up
An under-inflated tyre can reduce mileage, increase wear-and-tear and even burst. However, during long journeys, when tyres are likely to wear out quickly, drivers are in no mood to monitor their tyre pressure. As a brilliant alternative, Goodyear has come up with a self-regulating tyre that inflates itself on-the-go. The electronics and mechanical components are built into the tyre itself, and the technology is currently being used on 100-psi, re-treaded commercial usage tyres.

Inside:
Goodyear’s Air Maintenance Technology focuses on an internal regulator comprising pressure sensors and miniature pump, completely fitted inside the tyre itself. The power for regulator functioning is drawn from the movement of the tyres. Working is simple: A sensor on the interior detects when the pressure goes low. Immediately a valve mounted on the sidewall opens up. As the tyre rotates, the vehicle’s weight compresses a tube built into the tyre’s circumference to inject air into the tyre. Once the pressure reaches the programmed psi value, the system shuts the valve and the tyre runs as usual.
A social hearing-aid that imitates functional hearing
People using hearing-aids are often embarrassed by the lack of clarity in crowded places. Two researchers at the University of Toronto have floated a start-up called Cogni-Wave to achieve what they call ‘social hearing.’ Cogni-Wave is developing a hearing-aid that uses rotating microphones to filter environmental sounds, so that the person using the hearing-aid hears exactly like someone with functional hearing—one voice at a time.

“We have a prototype that utilises Bluetooth and radio frequency (RF) wireless microphones or headphones. We have had good results but we are still adjusting parameters and the system to optimise performance. We are implementing our algorithm onto hardware, that is, chips and circuits, to speed up the processing and better incorporate it into various forms of hearing enhancement devices,” says Brian Wang, co-founder, Cogni-Wave. These hearing-aids will hopefully hit the markets by the end of 2013.

Inside: Michael Shen, co-founder, Cogni-Wave, says, “We will use digital signal processor (DSP) chips for the core signal processing of our device; the specifics of the chips would match our algorithm parameters to achieve desired results. Directional microphone and miniaturised speakers are necessary for our design, along with the circuitry components needed to amplify or filter the received and outgoing signals.”
A camera that takes ‘living’ pictures
Lytro is the first consumer camera that captures the entire light field – that is, the rays of light travelling in every direction through a scene. Earlier, this used to be done in labs with hundreds of cameras and a supercomputer to collate the images. The scientists who made Lytro have combined all that technology into one small handy camera! This means you can take ‘living’ pictures that you can interactively refocus later, any number of times. There is a special format and software bundle that let you do a lot of things with your living pictures, and also share them with others.

Inside:
Lytro’s 8X optical-zoom, f/2 lens captures significantly more light than most cameras. A micro-lens array joined to a digital image sensor records the colour, intensity and direction of the 11 million or so light rays entering the camera. Their light field engine does the work of a super-computer, by processing all the light ray information and creating images that can be refocused anywhere, anytime. Since the engine travels with every file, others can also refocus shared images. The camera comes in a lightweight anodised aluminium structure with a touch screen.
A bouncy tool for police encounters
When scouting out suspects, police and military personnel always fear the unknown—how many criminals are inside a room, whether they have any dangerous weapons with them and so on. Similarly, firefighters would like to know how intense a fire is, how many people are stuck in the accident, etc. Bounce Imaging, a throwable electronic device, aims to help in such situations by capturing images and other information using cameras and sensors, and relaying it to a mobile device.

Inside: Still in the design stage, Bounce Imaging is likely to include six wide-angle cameras (that can together give a 360-degree view), each capable of taking two snaps per second and surrounded by infrared LED flash, a protective casing that allows the device to bounce without any breakage of components, a battery, a variety of sensors such as oxygen, smoke, temperature and radiation sensors, and an accelerometer and gyroscope to orient images. The captured data is sent wirelessly to an Android-based mobile device, where an application helps analyse the information. Developers are still working on some solution (perhaps a tether or motion capabilities) to retrieve the device after it has done its job.
A robot you can ‘teach’ to pack bread
Rodney Brooks has designed a unique robot that is easy to use, comparatively cheap and suitable for even small manufacturing outfits. Baxter can perform repetitive tasks like bread packing, working safely next to people. It exhibits ‘common sense’ and is capable of sensing and adapting to its task and environment. For example, let us say Baxter is assembling a small machine and it loses a part. It will visually scan the desk, pick up the piece and start working again—just like we do. The best part is that it involves no programming or costly integration. It is possible to train the robot by physically moving its limbs and demonstrating how it should work. You can easily update its capabilities through software updates, or create your own capabilities with an easy software development kit.

Inside: Seven degrees of freedom, 8-12 pick-and-place operations per minute, 1m/s arm speed, five built-in cameras, interchangeable end-effectors, force sensing, springs and force control at each joint for free movement and bump detection, behaviour-based intelligence, vision-guided movement, human detection using front camera and 360-degree sonar, navigator and face-like display for human-machine interface (HMI), casters for movement, locking feet for stability. Full specifications and parts list available at www.rethinkrobotics.com
Car of the future
Visteon recently showed off e-Bee—a concept car created using a Nissan Leaf. It has all the automotive electronics you want to see in your car in the future – and if Visteon’s estimate is right, your car might look pretty much like this by 2020. It has everything from entertainment and mobility solutions to safety and comfort.

Inside: Boxes and boxes of electronics, including personalised HMI, touchscreen instrument panels that give information on vehicle controls and social media connections, a head-down projected main display in front of the driver, a rear view with 360-degree visibility and augmented reality features, tech-agnostic wireless charging, Open Source infotainment platform, near-field communications for personal link between the user and vehicle, climate control system, cloud connectivity and car-to-car communications for improved information about collisions, hazardous roads, curve speed warnings, traffic flow and more. Most of the technology is based on an open platform.

A mouse that fits any palm
BMW Design Works and Thermaltake have together launched the Thermaltake Tt eSports Level 10 M gaming mouse, which can apparently be adjusted to fit to any palm size. It also includes several ergonomic features including a palm-cooling design.

Inside: The mouse features a hollowed-out design that allows height and angle adjustment of the mouse body by simple turning of a screen on the top side of the mouse. A perforated palm surface, advanced materials and unique shape manage to maintain a passive airflow that removes sweat from the palms. The mouse works using a laser sensor with a sensitivity of 8200 dpi, 128kB memory, LED lighting and USB connectivity. It comes bundled with the requisite software.

Cubical display for an immersive experience
Samsung’s NL22B is a cube-shaped device that contains a transparent 56cm (22-inch) front-panel display with a computer built into the chassis. It allows images and animations to interact with the products showcased inside the cube. Apart from creating an immersive shopping experience, it could also be used in fields like education and healthcare. It might, for example, be used in a store to allow users to interactively find out more about products and try out various combinations, before making a purchase.

Inside: 60Hz transparent LED display, protective glass, speakers, security lock and cables, USB input and Ethernet connectivity. Built-in AMD A4-3310M dual-core processor allows users to easily control the display, without the need for external PC. Embedded MagicInfo Premium software enables images or videos to be played from a USB source, or deployed and managed from anywhere in the world using a network.
A wristband that tracks your life
Larklife wristbands (one for day and the other for night) track your activity, diet and sleep; analyse the information holistically; and provide personalised recommendations to improve your lifestyle. Larklife provides context-aware advice – for example, if you did not get enough sleep in the night, it will suggest you a protein-rich breakfast to ensure enough energy.

Inside: An intelligent triaxial accelerometer helps pick up even micro-movements of the user’s body, while dietary information needs to be fed into the system. Bluetooth Smart helps synchronise this information with an iOS application on your mobile device. A continuous machine learning algorithm analyses the user’s activity and learns about his energy patterns. The techniques are apparently based on the science of circadian rhythms, or how individuals’ energy levels peak and dip. Lithium-polymer battery provides up to 48-hour working. Other components include micro-USB connector, vibration motor, clock and snazzy LED lights to grab your attention.

Bandai strengthens its bond with kids
Bandai created magic with Tamagotchi as early as 1996. Its new TechPet robot dog promises to be all the more phenomenal. It starts with a simple, free iTunes application, which lets kids take care of a digital pet. You can feed it, monitor its health, give it medicines, play with it, and do much more. However, the real kick lies in the robot model or toy, whatever you want to call it. Dock your iPhone or iPod Touch as the face of the pet, and it is ready to wag its tail and play with you. The robot toy is capable of walking front and back, turning 360-degree and dancing.

Inside:
This application-based toy works with an iPhone or iPod touch docked to the robot dog through a 3.5mm jack. iPhone’s Facetime camera allows voice and gesture control. Bluetooth lets the robot interact and play with other TechPets. The robot dog is powered by three AA-size batteries.

Making electricity safe and smart
Canadian company 2D2C, which makes electrical safety equipment, has launched the SafePlug energy manager kit that adds intelligence to normal power sockets. The outlets provide child safety and surge protection, monitor power consumption of devices connected to them, automatically switch off devices not in use, and also enable remote control of the outlet. Overall, the system promises 30 per cent savings in electricity bills.

Inside:
The kit comprises SafePlug energy manager outlets, a server, an application that can run on most mobile devices and Web browsers, and SafePlug Upgrade tags. The server and outlets communicate wirelessly using Zigbee Pro—a low-power networking technology that enables the devices to connect to each other and ultimately form a mesh network. The server can, in turn, connect to the device that runs the application using Ethernet or Wi-Fi. Outlets contain patented overload, shock and power fault circuit interrupter technologies. SafePlug Upgrade tags communicate appliance power and current rating to outlets. There are around 13 tags available, and for an appliance to receive power from an outlet, it must be updated by adding the tag that best matches its power or current rating.

Google’s shot at wearable computing
Google Glass is a computer-integrated pair of glasses that realises augmented reality. That is, it supplements what you see with relevant information. If you are walking down a street, it could pop up information on the buildings there, notify you of a traffic diversion or suggest a restaurant – somewhat like today’s location-aware phones can. It is likely to be launched around 2014, but has already gained a lot of attention.

Inside: Glass is likely to include a heads-up display; standalone processor; on-board memory and battery; projection technique such as the Lumus optical engine module; a 3.2MP camera and 1080p video recording; touch pad, microphone and speakers for input-output; sensors like gyroscope, accelerometer and magnetometer (e-compass) for context-sensitivity and gesture-enabled interaction; GPS functionality; and 3G/4G, Wi-Fi and Bluetooth connectivity. It is proposed to run on Android. Although the early prototype uses an opaque screen, the actual might use a transparent liquid-crystal display or active-matrix organic light-emitting diode display.
NASA’s best Martian bet
NASA’s Curiosity is the largest rover sent to Mars. The car-sized rover apparently contains much more scientific instrumentation than other rovers sent to the Red Planet. According to NASA’s Mars Lab, the rover has everything that a living thing needs to breathe, live and work.

Inside:
The rover’s body is a structure that protects the stuff inside. Computers are its brain, and temperature is controlled through internal heaters, a layer of insulation and more. The rover’s neck and head serve as a mast for the cameras to give the rover a humanscale view; the cameras and instruments are its eyes and senses. It has robotic arms and hands to collect material samples for study, wheels and legs for mobility, batteries for energy, and ultra-high frequency antennae to communicate! One of the two computers inside the rover works all the time, while the other serves as backup. Both use radiation-hardened BAE RAD750 microchips operating at up to 200 MHz. Each computer is equipped with 2GB flash memory, 256MB random-access memory and 256kB erasable programmable read-only memory. While this configuration seems much lower than today’s computers, these chips are used because they are radiation hardened, through a very high-tech and costly process to stand the rigours of a strange planet.

DIY Game: Glow All the LEDs First!


DIY Game: Glow All the LEDs First!


This is a 2 player game, based on 8051 microcontroller AT89S52. This game features two push buttons (one for each player) and an array of 8 LEDs for each. It demands high reflexes, as you have to push button as fast as you can. Each press would help the successive LED to glow until all the 8 LEDs are on.

The competition is about how fast you can toggle (Press and then un-press) the buttons, greater your speed of pressing push button, greater will be your chance of winning. As soon as any of the two players reach the last LED, the push button of another player will get deactivated, which means it will not respond to the push. Also the LEDs of the winner will start toggling. This will ensure the accurate after results. To restart the game, press the reset button (button connected to pin 9 on microcontroller).

Press the Button as Fast as You can
Press the Button Fast Game
LEDs corresponding to PLAYER 1 are connected to PORT 2 whereas for PLAYER 2, LEDs are connected to PORT 3. Push buttons are connected to pin P1.1 and P1.2 for PLAYER 1 and PLAYER 2 respectively. I have used integer variables “pressed[0] and pressed[1]”(in coding part) to ensure that microcontroller counts only those push which are done after the release of the button. This will ensure fair play.

I have also declared an array arr[], which comprises the hexadecimal values for the LEDs to glow successively. I have also created a delay function: delay_msec(), using TIMERS to provide delay (in milliseconds) wherever necessary.

Since 8051’s cannot multitask, thus to judge the 2 players individually I have written the code in such a manner that it seems to perform multitasking. This was needed to count each and every perfect push and hence result in a fair decision game.

Wire Loop Game


Wire Loop Game


This is one lesson from a Simple Circuit Unit that I created for middle school and high school students. It is fun and involves hands-on learning. For more cool hands-on engineering projects check out Machine Science
http://www.machinescience.org/catalog

Step 1: Simple Circuit Games Unit 1: Wire Loop Game

If you have ever been to a carnival or an amusement park, you may have seen or played a simple hand-eye coordination game involving a metal loop on a handle and a length of curved wire. In this game, the player holds the loop in one hand and attempts to guide it along the curved wire without touching the loop to the wire. In the carnival version, shown in Figure 1, the handle delivers a mild electric shock to the player when the loop and the wire touch, signaling that the game has been lost.

In this project, you will build your own wire loop game, using wires and batteries. In your game, players won't receive shocks if they lose. Instead, a buzzer will signal whenever the metal loop touches the curved wire. The wire loop game has two challenges. In Challenge 1, you will learn how electricity from a battery can be used to make sounds. In Challenge 2, you will build your own wire loop game and then play it.

Step 2: Challenge 1: Using the Buzzer

Challenge 1 will give you a chance to experiment with the buzzer that will signal when players lose the game. Along the way, you will learn about electric circuits.


Collecting Your Components
In order to complete this challenge, you will need the following components:

Part Quantity Description
A 1 Battery pack
B 1 Buzzer
C 1 Foam core
D 4 Machine screws (1/2", 4-40)
E 4 Machine screw nuts (4-40)
F 4 Washers
G 2 Insulated wire (12" lengths, 24 gauge)
H 1 Battery lead extender

Step 3: Tools

You will also need the following tools

Tool Quantity Description
A 1 Utility knife
B 1 Cutting mat
C 1 T square
D 1 Wire stripper
E 1 Scissors
F 1 Screwdriver

Step 4: About Circuits

A circuit is a pathway that carries electricity from one end of a battery to the other. Chemical processes inside the battery create a pressure known as voltage that pushes electricity forward whenever a complete pathway is present. If the pathway is broken at any point, no electricity flows through the circuit. This is what happens when you shut off any battery-operated device: the circuit is interrupted, and electricity stops flowing.

In circuits with batteries, electricity always flows from the end of the battery marked with a minus sign (-), called the negative or ground end, to the end marked with a plus sign (+), called the positive or power end. In most cylinder-shaped batteries, including the AA batteries used in this project, the power end has a small raised tip, whereas the ground end is flat. Figure 3 shows a simple circuit, with a battery and a light bulb.

Step 5: Making the Buzzer Sound

The buzzer can be made to work by connecting it directly to the battery pack. The buzzer has two short lengths of wire, called leads, for making electrical connections. The buzzer's red lead should be connected to the battery pack's red lead, and the buzzer's black lead should be connected to the battery pack's black lead, as shown in Figure.

1. Make sure the power switch on the battery pack is in the OFF position.

2. Insert the buzzer's red lead into the red wire side of the battery pack's wire harness.

3. Insert the buzzer's black lead into the black wire side of the battery pack's wire harness.

4. Move the switch on the battery pack to the ON position. The buzzer should make a sharp sound. If it does not, make sure that the buzzer leads are inserted far enough into the battery pack wire harness and check to make sure the red and black wires are not reversed.

Step 6: Challenge 2: Build the Wire Loop Game

In Challenge 2, you will use your knowledge of circuits to create a small-scale wire loop game. Remember: the object of the game is to move a wire loop around another wire without touching the two wires together. If the two wires touch, the buzzer will sound.

Step 7: Cutting Out the Base

As a base for your game, you need a rectangular piece of foam core measuring about 4 inches by 9 inches. In some cases, you may need to cut this base piece from a larger piece of stock.

1. Mark your measurements on the foam core.

2. Make your cuts with a sharpened utility knife, using the cutting mat to protect your work surface, as shown in Figure.

*note: It is best to use a metal straight edge

Step 8: Applying a Game Board Image

If you want, you can apply a printed image to the top of your game board, gluing it in place as shown in figure. A printable version of the image shown in Figure can be downloaded below. Otherwise, you can use any image you like. When gluing down the image, be sure to leave about 2 inches of foam core exposed for making electrical connections later.

1. Apply a thin layer of glue to the back of your image, as shown in Figure. Be sure to cover the entire surface evenly.

2. Press the image into place, aligning the bottom edge of the image with the bottom edge of your top panel, as shown in Figure. REMEMBER: There should be about 2 inches of uncovered space at the top of the panel.

Step 9: Adding the Path Wire

The path wire is the length of wire that players must navigate to win the game. It is secured to the game base with machine screws, nuts, and washers, as shown in Figure.

1. Choose one of the two lengths of insulated wire to be the path wire.

2. Strip all of the insulation from the path wire.

3. Twist the path wire into a challenging but navigable shape.

4. Using two machine screws, secure the two ends of the path wire to the foam core base, as shown in Figure.

Step 10: Adding the Loop Wire

The second length of wire will be your loop wire wisted back on itself to create a loop that must be navigated along the path wire.

1. Strip about 1 inch of insulation from one end of the loop wire, and strip about 3 inches of insulation from the other end.

2. Secure the shorter stripped end to the game base with a machine screw, as shown in Figure.

3. Make a loop in the other end of the loop wire, encircling the path wire, as shown. (NOTE: Do not make the loop too small, or your game will be very difficult to win!)

Step 11: Adding the Buzzer

The buzzer can be mounted directly to the game base. Because these components need to be incorporated into a circuit with the path wire and the loop wire, they must be positioned close to the machine screws that anchor these two wires, as shown in Figure.

1. Using the buzzer as a template, trace the component's rectangular shape onto the game base, between the two machine screws at the top of the game board.

2. Carefully cut out the rectangle and push the buzzer into the hole. If it feels loose, secure the buzzer with tape.

Step 12: Making the Electrical Connections


wireloopbatterylead.gif
Picture of Making the Electrical Connections
wireloopbatteryconnect.gif
Now comes the tricky part connecting the path wire, the loop wire, the buzzer, and the battery pack, so that when the loop wire touches the path wire, they form a complete circuit that causes the buzzer to sound.

1. With the game board upside down, identify the buzzer's power lead (the red wire) and ground lead (the black wire).

2. Loosen the nut anchoring the loop wire, wrap the buzzer's power lead around this screw, and retighten the nut.

3. Find the screw that is connected to neither the path wire nor the loop wire, wrap the buzzers ground lead around this screw, and retighten the nut, as shown in Figure.

4. Secure the battery's power lead to one of the two screws anchoring the path wire.

5. Secure the battery's ground lead to the screw with the buzzer's ground lead, as shown in Figure.

6. Connect the battery leads to the battery pack, making sure to align the red and black wires.

Step 13: Playing the Game

Now the fun part: turn on the battery pack and try to move the loop from one end of the path to the other without touching it, as shown in Figure.
