Geotag a Photographic Record of Your Next Road Trip

Sure Shots Special firmware allows you to set the camera to automatically take a picture at regular intervals, while the GPS records the location.

Use a GPS, a dashboard-mounted camera and special software to create a photographic record of your next road trip. I’ve always loved taking pictures from the road when I travel, but on returning home I often had no idea where I had shot many of them. The only way to figure it out was by placing them on a timeline and working backward through my route. Recently I found a way to make it easier. I mounted a Canon digital camera on the dashboard of my car, installed software on it that enables it to automatically shoot pictures every few seconds or minutes, and set up a GPS unit to record the location of each shot. When the trip is over, I just load all the photos and the GPS track data into a geotagging program, which matches the images with the locations. A variety of programs are available, including free, open-source applications such as Geotag (geotag.sourceforge.net) and a plug-in for Aperture, Apple’s high-end image-management software. I chose to use JetPhoto Studio Pro, a great app that runs on both Mac and Windows that you can download for $25 at jetphotosoft.com. The software plots my trip photos on a map, along with any text captions I want to add, using Flickr, Google Maps or even Google Earth: instant travelogue.

1. Download the CHDK software from chdk.wikia.com and load it onto an SD card. Put the card in your Canon camera and boot it with the new firmware, which will let the camera automatically snap pictures at regular intervals.

2.Download and install the script (from popsci.com), which lets you set the interval for shooting.

3.Set your GPS to begin logging a “track.”

4.Mount the camera on your dash (with shot settings on Auto), pointed at the roadside over your hood, and go for a scenic drive.

5.Download the GPS log file and the pictures to your computer. Open the geotagging software. Load the pictures and the GPS log file, and tell the software to perform its geotagging magic. If you’d like to see your trip plotted on a map, use the software’s “export to Google Earth” function. By modifying a few settings, you can also have pictures automatically placed on a map when you upload them to Flickr.

Tomorrow's Hybrid

The ReCharge, Volvo’s concept plug-in hybrid could squeeze 160 miles from a gallon of gas by tossing out the power-wasting transmission. It packs a small electric motor inside each wheel so that no power is lost in the drivetrain. Here’s a look at the next generation of fuel-efficiency.

How Wheel Motors Drive the Car

Putting electric motors directly inside the wheels eliminates the transmission, which typically wastes 10 to 20 percent of the engine’s energy. An interior disc mounted to the wheel bearings contains a series of independently controlled electromagnets, which emit a magnetic field in response to an electrical current. Around that an outer ring contains permanent magnets. Step on the accelerator, and a computer in the interior ring begins to rapidly switch the polarity of the electromagnets, repelling or attracting the permanent magnets. The faster the polarity changes, the faster the motor spins the wheels.

The challenge is controlling four independent motors. If one spins even slightly faster, the car could veer violently. The ReCharge team’s next big hurdle is refining the software that maintains precise control. As for performance, the car will have permanent all-wheel drive with no gearbox standing between your foot and the motors. In other words, it should go like a rocket.

Batteries power all four motors and the car’s electronics. Unlike most plug-in hybrids, the ReCharge uses a lithium-polymer (rather than lithium-ion) battery. This is not only safer,it also uses sheets of plastic instead of a volatile electrolyte solution. However, it also powers the car for 60 miles before the engine kicks in to recharge it. Small lithium-polymer batteries have started to show up in gadgets such as the iPhone, but Volvo gets its larger, experimental versions from an undisclosed manufacturer. A plug-in concept from Volvo brings the power inside the wheels for increased efficiency and extra mileage.

The engine charges the battery when the car isn’t plugged in. The concept design calls for either a 1.6-liter flex-fuel or turbodiesel engine, but since the engine doesn’t have to actually spin a drive shaft, a fuel cell or a second battery could do the job just as well. It would kick in to recharge the battery only after the battery was at 30 percent capacity, so the ReCharge could travel 160 miles on a single gallon of gas.

A charger feeds power to the battery when the car is plugged in at home. Eventually, the ReCharge will be equipped with an intelligent version that can automatically sense strain in your area’s electrical grid and either cut back its power consumption or feed electricity from its battery back into the system.

Tires must be as thin as possible since the motor makes each wheel bigger.The ReCharge uses specially designed Michelin tires with a soft, resilient surface that also reduces rolling resistance.

Gray Matter: How to Start a Fire With Only Compressed Air

Piston Pyro: A thick-walled acrylic tube with aluminum plunger (from $45; survivalschool.com) forms a demonstration fire piston. It reveal a bit of cotton set alight by pressure alone.

You’ve probably seen contestants on Survivor trying to make fire by rubbing sticks together or concentrating sunlight with their eyeglasses. But, among preindustrial fire-starting methods, it’s hard to beat the portable convenience of fire pistons used in Southeast Asia since prehistoric times.
Almost all gases heat up when compressed. The harder and the faster the compression, the hotter the gas gets. It is hot enough even to ignite cotton wool or other flammable materials. Diesel engines also work the same way. They have no spark plugs but rather, the fuel/air mixture is ignited by compression as the cylinder closes up.

Perhaps most surprising is that this same principle also explains how many high explosives work. They are called “high” because their explosive reaction expands through a supersonic pressure wave that travels much faster than ordinary burning that makes them far more powerful than low explosives like gunpowder. Each successive bit of material in a high explosive ignites when the pressure wave compresses and heats trapped microscopic bubbles of gas. When manufactured without bubbles, even extremely powerful high explosives can be impossible to detonate. Without gas to compress, there is no way for the detonation wave to heat up neighboring areas.

For example, ANFO (ammonium nitrate/fuel oil) explosive mixtures, commonly used in mining, don’t always naturally contain enough trapped gas, and require a “sensitizer” to render them reliably explosive. It's often just a slurry containing hollow glass microspheres.

Some high explosives also create heat through the friction of microscopic crystals rubbing against each other. However, in many cases, the difference between bang and no bang is just hot air.

Fancy Fire is another type of igniter that just also need compression of gas. A beautifully made wood-and-metal fire piston with a cost from $65 (wildersol.com); designed for lighting campfires or other survivalist needs Mike Walker

The Deepest Drill

A massive floating laboratory is attempting to drill through four miles of seabed to take samples of the Earth’s mantle.

The world’s deepest drill is about to get taller—tall enough to dig into Earth's mantle. Already, the Chikyu research vessel is capable of fetching samples at depths of 23,000 feet below the seabed, two to four times that of any other drill. In 2007, off the coast of Japan, it became the first mission to study subduction zones, the area between tectonic plates that is the birthplace of many earthquakes. Over the next three years, scientists will tack on at least an extra mile of drill and attempt the most ambitious mission ever: piercing the Earth’s mantle. There, scientists expect to find the same conditions as those in the early Earth—and perhaps the same life-forms that thrived then.

Design Highlights of the Chikyu Research Vessel

Derrick: The main hoist winch and a system of elevators lifts 1,250 tons of pipes and machinery through the 72-foot-wide opening in the bottom of the ship.

Riser Pipe: A four-foot-diameter steel pipe called a riser connects the ship to the borehole. Outside the riser are several hoses and smaller pipes for recirculating the synthetic mud and controlling the blowout preventer. The riser’s inner hollow core (a pipe within a pipe) is reserved for the drill string. At a 1.6-mile depth, the assembled riser weighs 1,000 tons.

Planned UpgradesTo drill in deeper waters, engineers will either replace the steel riser with one made from a lightweight material like carbon-fiber-reinforced plastic or they will use two pipes—one for the drill string and a second, small-diameter pipe to return the spent drilling mud back up to the ship for recycling.

For deeper ground penetration, where temperatures can exceed 500°F and corrosive chemicals reside, engineers will use a higher-tensile-strength steel to build the drill string. Also in development are new drilling muds that cool the drill bit during operation.

Blowout Preventer: This five-story machine sits on top of the borehole and monitors the intricate balance of pressure within. If it detects a sudden increase in pressure, it can seal off select valves or the entire hole to prevent an explosion.

How to Reach the Mantle

1. Get in Position Using GPS and transponders on the ocean floor, the ship’s positioning system measures the forces acting on the craft, such as wind, wave and current direction and speed. Six computer-controlled propellers will keep the ship from drifting more than 15 feet in any direction.

2. Assemble Drill To break through the first layer of crust, the crew deploys a steel pipe with an 11-inch-wide drill bit at the bottom. The crew attaches new lengths of pipe one by one from the top until the “drill string” is long enough to hit the seafloor.
3. Start Drilling As the drill bit burrows through sediment and rock, a hose in the drill pipes in a synthetic mud to keep the drill cool and the borehole open under the crushing pressures found at those depths.

4. Collect Rocks Every few hundred feet, scientists collect rock samples for study. A narrow barrel with a razor-sharp edge (think of a very big apple corer) shoots down and pierces the undrilled layer of earth below. The 31-foot-long core samples are analyzed for their chemical and magnetic properties.

Synthetic Mud: A viscous cocktail of minerals, polymers and seawater stabilizes the borehole walls. Because the mud is expensive and could be harmful to ocean life, it is recycled back to the ship during drilling.

The Next Generation Wind Turbine

To take advantage of the strong winds that blow over the ocean, this gearless turbine uses a giant ring of magnets and 176-foot blades . There’s enough wind energy along our coastlines to power the country four times over, and the race is on to build the best offshore turbines to capture it. Manufacturers worldwide are experimenting with two techniques: ever-longer blades to harness more gusts, and simplified drivetrains (including new generators) that slash the need for costly repairs at sea. GE’s upcoming machine, slated to go online in 2012, will combine both into one package.

A Twist on Blades: The longer a turbine’s blades, the more wind it captures and the more electricity it creates. “If we could, we would just build infinitely longer blades,” Mercer says. “The problem is, blades get heavy and flexible.” That flexibility, coupled with the force from very high winds, can bend blades so much that they burden the machine or even smack the tower. So GE designed a blade that twists as it bends. It’s curved backward about eight feet, instead of extending straight out. When a gust pushes the tip up, the blade twists slightly around its curve—instantly angling itself so that it bears less of the gust’s brunt yet still captures a large part of its energy.

GE created lightweight 176-foot blades—about 40 percent longer than the average—with a more aerodynamic shape. The blades will attach to a drivetrain that does away with many of the moving parts, including the gearbox, that are prone to breakage and energy loss. A direct-drive mechanism replaces gears, and permanent magnets replace the electromagnets that require starter brushes, coils and power from the grid every time they fire up. The blades are now being tested in the Netherlands, and the drivetrain in Norway. Combining the two should result in a turbine that captures 25 percent more wind power than conventional models, so it can operate more often at its full four-megawatt potential—enough to power 1,000 homes.

Design Highlights on the Windmill
Generator: The 90-ton generator consists of a nearly 20-foot ring of magnets that spins to produce current. Its large diameter lets it create a lot of power when turning slowly, at the same 8 to 20 rpm as the blades, so it doesn’t need a gearbox to speed it up to the thousands of rpm most megawatt generators require. “Get rid of the gearbox, and now you don’t have to change the oil,” says GE engineer Gary Mercer.

Electrical Circuitry: Converters stabilize the current’s varying frequencies. Transformers boost voltage from 690 volts to more than 22,000, so current travels efficiently over long-distance lines.

Pitch Controller: To maximize lift as the wind speed changes, a controller can automatically rotate each blade anywhere from a fraction of a degree to multiple degrees per second. It can also turn the blades away from dangerously high winds to avoid power overloads or hardware damage.

Blades: Light, stiff carbon fiber replaces fiberglass at critical points in the blades, so they lose pounds and gain strength. A flat (rather than tapered) edge gives them a shape that increases lift.

How to Spin Power
1. Position the BladesBased on data from wind-direction sensors, a yaw-drive motor turns the nacelle to face the wind. A pitch controller rotates each blade around a bearing, setting it to the best angle for the wind speed.

2. Capture the WindThe three-bladed rotor spins in winds from 7 to 70 mph, sweeping twice the area of a football field. A 23-foot-long steel rotor shaft and two roller bearings transfer the mechanical energy to the generator.

3. Turn it into ElectricityThe shaft spins the generator’s neodymium magnets inside stationary copper coils, inducing current in the coils. Circuitry adjusts the frequencies and voltage of the current and sends it off to the grid.

Bike's Electric Shock (Simon)

Cannondale's Simon is the first completely computerized bike-suspension fork. It features a hydraulic shock that can instantly change its resistance and how far it travels. Meanwhile, motion sensors and a computer calculate the best settings for the trail. If you suddenly launch off a jump, the shock softens for a smoother landing. Once it reaches a flat area where your pedaling hard, the shocks firms up to boost your power. Simon is currently a prototype, but cannondale expects pieces of the technology to arrive on bikes within a few years.

How It Works:
1. A joystick lets riders select among five preset settings, such as “DH” for swallowing up big downhill impacts. You can also elect to have the suspension continually recalibrate itself.

2. A motion-sensing accelerometer in the front fork detects bumps and impacts. Meanwhile, an optical sensor inside the shock keeps track of its position, gauging how open or compressed it is.

3. Info from the sensors is sent to a computer 500 times a second. Software decides how to change the suspension based on how many bumps you’ve hit, how far the shock can still move, how fast you’re going, and more.

4. An electric motor adjusts the shock. It’s a typical hydraulic shock in which a piston pushes oil through a valve, but the motor changes the valve’s size. Smaller means less oil flow and a firmer ride, while larger means a more cushiony ride.

5. The shock readjusts with thousandth-of-a-millimeter accuracy every seven milliseconds. It protects you from bumps faster than the human brain can register them,much less react.

The Lab That Fits In Your Hand

A piece of plastic as a size of a credit card. It is combined with a book-size gadget that can diagnose as many deadly diseases as big laboratory machines can. Among all of the innovations, it can process results quickly and it can be purchase cheaply.

Most blood tests require shipping vials off to a lab, followed by several days of nail biting. This kit is one of the first that can diagnose multiple diseases on the spot, shrinks an entire lab into a two-piece portable package that even novices(beginner) can use. A disposable, $1 plastic card, formed through injection molding, holds miniature versions of test tubes and chemicals. In place of technicians or $100,000 machines, a battery-powered, $100 gadget mixes the molecules. The prototype from Claros Diagnostics and Columbia University bioengineer Sam Sia, is currently being tested in Rwanda where potentially lethal diseases like HIV/AIDS often go undetected. Sia’s latest study estimates that global access to a low-cost test for syphilis, for example, could prevent a million stillbirths a year. “In the U.S., point-of-care devices like this are attractive because they are more convenient,” Sia said. “In developing countries, there is simply no alternative.”

The Lab That Fits in Your Hand The handheld analyzer contains a microprocessor, a micropump, photodetectors, LEDs, and a nine-volt battery that powers them all for two weeks. Designed in conjunction with the company Smart Design and Pratt Institute’s Design Incubator, it measures 9.5 by 4 inches.

Step-By-Step procedure of using the device

1. Add Blood Sample: A worker draws a drop of blood into a tube and attaches the tube to holes in the card. Then she puts the card into the handheld analyzer. Inside, a micropump—essentially a small vacuum—sucks the blood through a series of detection zones made up of tiny zigzagging channels.

2. Trap Signs of Disease: In each zone, the walls are lined with a different antibody or antigen—a molecule that binds to disease-indicating proteins—that makes those proteins stick to the sides as blood flows by. One zone captures anti-HIV antibodies, one collects syphilis markers, and in the future, the other zones will trap more STDs. The blood passes a blank zone, used to rule out false positives, and pools on paper to avoid a mess.

3. Make the Signs Visible: Microscopic disease proteins are hard to detect, so two kinds of molecules turn them a color that the analyzer can measure. The molecules (prepackaged in the card) travel to the detection zones when the vacuum sucks them up through channels, across the blood-sample tube and down to the detection zones. (The path lengths ensure that the molecules reach the zones in the right order.) The first set, antibodies tagged with gold nanoparticles, attach to any captured proteins. A silver development solution follows, plating onto the gold particles to form easily seen silver.

4. Get the Results: The solid silver is visible to the naked eye, but a photodetector in the analyzer measures the intensity of each zone more exactly. That lets it determine if there’s enough silver, and thus enough trapped proteins, to indicate disease. Then it flashes yes or no on its digital display—with accuracy similar to lab tests—just 20 minutes after the first finger prick.

The Most Advanced R/C Car

This 18-inch 0ff-roader is made for play. However, it packs an engine, starter and sensor system that are just like a real racecar at a tenth of the size.

Gas-powered remote-control cars provide realistic racing fun. They burn a gasoline-like fuel called nitro (made of methanol, nitromethane and lubricant) with miniature internal combustion engines. Losi's Ten-T gets even more authentic by adding a starter that works like a diesel engines. Nitro cars are usually hard to start. You have to pick them up, use a hand-held motor to spin the engine, and simultaneously work the remote's throttle. With the Ten-T you just hit "start" on the remote. That turns on the car's own electric motor, powered by a 7.4-volt lithium-polymer battery. The motor turns a starter shaft behind the engine, which spins the crankshaft until the engine's suction draws in fuel. Meanwhile, the battery also lights a glow plug, similar to a spark plug, in the engine. The plug's hot element, combined with the compression of the fuel-air mixture when the piston rises, ignites the fuel. Then the plug keeps glowing and the fuel keeps burning until you're ready to call it quits.

Design Highlights on the R/C Car

Telemetry:The Ten-T is among the first R/C vehicles to come with a built-in telemetry system, similar to those in a pro racecar. Sensors on the car continuously beam data on speed, temperature and battery voltage to a display on the remote.

Fuel Tank: The 2.5-ounce tank includes a weighted pickup tube that follows the liquid as it sloshes around, ensuring that it can grab and deliver fuel even when the car drives up a steep hill. A full tank runs the engine for about 10 minutes (standard for high-power nitro cars), and it's refueled from a squeeze bottle.

Engine: The single-cylinder, 3.4cc engine provides 1.8 horsepower, enough to send the 6.2-pound car up to 45 mph in a few seconds.

Drivetrain: In the four-wheel-drive vehicle, the engine transmits power to the wheels by engaging a clutch and kicking off a series of gearsets that lets each wheel spin at a different speed. Dual disc brakes stop both the front and rear axles.

Suspension: The front and rear suspensions are adjustable to tackle many terrains. Shifting the control arm alters ride height, camber (the vertical angle of the wheels) and toe-in (the degree they point in or out). Turning a collar on the oil-filled shocks changes springiness.

Steering Servo: This small, high-torque electric motor moves the wheels' control arms. You can tweak its movement from the transmitter -- for instance, to alter the distance it turns with each command or limit the steering angle to speed over straight tracks.

A Lean Mean Nail Gun.

Bosch reinvents and upgraded common nail gun. Bosch made an average nail gun more efficient. As shown in the diagram, the "Bosch Full Force Nailer" was smaller than the normal nail gun, but, it has a driving power of the big guns.





Nail gun that are moved by air pressure (Pneumatic Nailers) can slash the time it takes to fasten everything from window trim to roof rafters. The basic body parts of the tool haven't change since 1960's. The nail gun still use compressed air that pushes a piston that drives a rod, forcing nail deep into wood before the tool resets for the next nail. NOw, Bosch had figure out how to make a nailer 20% smaller but having a boosting power of 10% so that it can drive nails into hard woods like walnut with less pressure than other guns. Instead of reserving some of the compressed air for resting the pistons, which weakens the strike, the tool uses all of the air's energy to drive the nails. A vent exhausts the air and a second bust return the pistons. Since Bosch nailer can operate at lower pressure, it reduces wear on compressors and components while still hammering 1 to 2.5 inch long nails all day.

Design Highlights on the Nail Gun
Self-Cleaning Filter: The pressurized air leaving the tool cleans this filter, which captures debris like sawdust and dirt, preventing it from clogging the cylinder.
Fitting: A connection to an air hose allows pressurized air to flow from an electric air compressor into the nailer, where it’s moved by valves controlled by the trigger.
Bump Firing: Like most nailers, the Bosch also has a semiautomatic mode called bump firing, in which you can hold down the trigger and fire a nail just by pressing the nose to the wood. A toggle switch on the trigger changes the position of a metal lever inside so that it touches the trigger-valve pin. At that point, depressing the nose pushes the metal lever into the pin, activating the trigger.
Depth of Drive: A dial lets you adjust the distance between the nose and the board, which changes how deeply the gun drives the nail.

Step By Step
1. A spring in the magazine feeds forward sleeves of 16-gauge nails one at a time, putting one directly under the driver blade.
2. Squeezing the trigger opens the nailer’s main valve, letting in air from a compressor that sets the 33-gram aluminum piston in motion.
3. The driver blade, a 5.3-inch steel rod attached to the bottom of the piston, smacks the nail, driving it into the wood.
4. Just behind the nose is a plastic vent that exhausts all the air as the piston descends in less than 0.1 second, so it meets with almost no resistance. A second burst of compressed air pushes the driver blade and the piston back up, ready for the next strike. In conventional nailers, a reservoir captures some of the air and rechannels it to push the piston back into position.

The shock bullet

One of the many amazing machines that interest me is a electric shot gun shell.This bullet is a shotgun slug replace lead with electronics to deliver a nasty but non-lethal jolt. The electric shotgun shell has a electric shock power that temporarily paralize a person within 20 seconds.

Most users of the shock bullet("XREP" extended Range Electronic Projectile) are Law enforcers that are in the line of duty. Everytime a cop patrol spot a mugging in a side of a town, the "XREP" comes in handy. When chasing a crook in the alley and trying to get away, a cop can shoot him at a maximum range of 100 ft with the innovative electric shock shotgun shell.

Unlike the average air taser, the XREP demonsrate safer and has farther range of penetration. It is impossible for a suspect to get away. It includes that a crook cannot harm the cops in some cases when a crook tried to retaliate because of the XREP's range.

The biggest challenge that this bullet acheive was minituration. The Taser contain high capacity of 50,000 volts which is good enough to penetrate a cloth. In the other hand, XREP only consumed 500 volts to allow smaller circuity.Instead of arcing the current, it sends it directly into the body via barbed electrodes that pierce the skin.Based on the lead engineer Mark Hanchett, "the key isn't so much about the voltage but the waveform". The current shaped to mimic electrical signals in the body and jams the body.

Design Highlights on the Electronic Shotgun Slug:
Nose: On impact, four electrified barbs on the nose of the projectile hook into the skin, delivering a small, localized shock across a six-inch area. This is merely a prelude to the bigger shock that will soon follow. The force of the impact breaks a series of pins that allow the projectile’s chassis to separate from the nose and dangle downward from a live copper wire.

Barbs: If the assailant fails to grab the wire to complete the circuit, six longer barbs on the projectile can also penetrate the skin. With the plastic sheathing removed on impact, the half-inch electrodes—called “chollas,” after a fierce cactus plant native to Arizona’s Sonoran Desert—pop out like spikes and swing into the body.

Hand Trap: The assailant’s natural instinct is to grab the dangling wire and rip out the barbs, but the wire is pulsing with current—touching it allows electricity to flow from the first set of electrodes in the nose of the projectile to the assailant’s hand, which contracts from the shock and squeezes tight around the wire so he can’t let go. Electricity now freely flows through his body, causing about 20 seconds of paralysis.

Fins: When the slug leaves the shotgun, three fins deploy from its tail, helping the projectile stay on track as it sails up to 100 feet toward its target.

Transformer: This converts energy from the battery to discharge 1.3 milliamps of current for 20 seconds. The power is relatively weak; in comparison, a wall outlet delivers about 20 amps. More important is the way the current propagates and interacts with electrical signals in the body. “If you get the waveform right, you can overwhelm the nervous system,” says Taser engineer Mark Hanchett.

Microprocessor: Once the circuit is complete, an onboard computer commands the voltage capacitor to fire, modulating the intensity, duration and shape of the current.

Power: Two lithium batteries power the microprocessor and electrical circuitry.

Shell: The circuitry is potted inside shock-absorbing plastic to ensure that it survives the force of the shotgun blast and collision with the target.

My first blog

Im passionate about amazing machines and this is my first blog. I enjoy inquiring knowledge and informations in regards about different kinds of new invented machines. Looking from simle to complicated kinds of machines gives me adrenalin rush to explore the purpose and their characteristics. This explains that my heart keeps on pounding fast when I saw from the magazine "Popular science" a certain machine such as a drilling machine that can drill into the earth's mantle. How cool is that! The time is just like a glimpse of an eye when human species started to evolve. The human species evolved from a pea brain person into a master mind. This reminds and shocks me when erly humans strugles to make simple machines such as spears which they use for hunting food. In the other hand, we as the modern human species cann't only drill a hole in the earth's surface, but can also travel into the moon and were already planning on colonializing Mars.


The human inventions are so fascinating that things that we called impossible in the past can now be made and explain by science.

I made this blog not only to learn as an individual, but rather also to share my knowledge that I gain through experience to the other people around the world. I would be posting some blogs in regards about some of my projects in my physics class.
