This seems complicated but really it is not. If you want to build your own, pull an old vcr or dvd apart and remove the motor. Easily make your own blades with spoons and a water bottle lid. See our other designs of wind turbines and complete instructions. The turbine has survived almost four years and a brutal winter. Blades have changed and some parts replaced but the motor still going strong. A good alternative to the store bought wind-turbine science kit which by the way uses a cheap motor and really sucks.

Reply 4 years ago on Introduction. Question 9 months ago. Answer 9 months ago. The motor is being used as a generator. The magnets and the copper coils in the motor excite the electrons and causes them to move. In this example the electrons are turning on a small red LED light. Subscribe to see when we update. We are regularly adding science hands on. Question 9 months ago on Step Since it's such a little blade you could probably correlate voltage output to wind speed but you'd need something like a arduino to calculate.

But it would much easier to use a rpm sensor. We understand that step-up motors work the best. We are using a red LED because it takes the least amount of energy to light up.

A white LED will work. Vertical blades will work but that would look totally different then what we show here. Larger blades will spin in lower winds. We hope this helps. I would advise strongly against holding the Tee in your hand when drilling holes, etc.

Those kinda injuries suck big time. Second that. I got a few smaller injuries from re-purposed screw drivers and hand tools. I am now retraining myself to avoid these stupid injuries:. In what direction will the tool go if the attempted step fails? In step four: The punch will either go into the thumb, the index finger, or less likely into your palm.

The last one can be avoided by limiting the movement of the right hand: putting the connector down and resting the hand on a board or book while pushing. For the drilling, the connector could be held end to end in a cheap clamp, or add a piece of pvc and hold on to that, so your hand is further away.

Possibly add a large PVC pipe cap to the motor shaft and covering the motor section to provide rain protection for the motor. Make larger propeller vanes from slices of PVC pipe. This could provide more power generation at slow wind speeds. More by the author:. She inspired me to take my love of science, and the fun I have with my students, to as many people as I can. Both my daughters hel We have ours in the backyard and it looks so beautiful glowing.

Add Teacher Note. Put the o-ring onto the front of the motor. Placing the o-ring just over the edge of the tee, mark the end of the motor.

This is where we are going to drill. Make sure your mark is in the center of the tee. Use a punch or pick to make an indentation. This way the drill will not slip around. Drill the hole large enough for the red LED to go through. Take your red LED and your motor. Find the long leg of the LED the wire that sticks out of the light that is longer. The longer LED is the positive and the short is the negative. Then connect the short leg to the - side.

Do this by placing the wires through the tiny holes. Bend tabs or the wire to keep the wire in place. Put the blades on to the motor and blow really hard. Does the light turn on? Go on to next step. Try blowing harder. Try switching the connection of the LED legs. Line LED with the hole. Straighten up motor while pushing LED through the hole.

Once the glue has started to dry, set the tee and propeller to the side to dry. Take the union and open. Remove the o-ring found inside. This will allow for the turbine to rotate easier. Press in firmly. Place plastic onto glue. Press firmly. Allow to dry. Tighten or loosen the union depending on your needs. Glue all pieces together if desired. Paint for a finished look.

Look through all of the spare parts from the VCR and pick out pieces that you think could be used to mount the motor to the pinwheel shaft. I found about three possible candidates, but settled for a slightly bent small piece of metal that I could easily screw the motor into.

Normally, a small electric motor will contain pre-drilled screw holes. You can use these in order to help mount the motor. I chose the piece of metal because when I compared it to the other possibilities, it seemed to have the most durability. The other great thing about using a piece of metal for the motor mount is that you can bend it in order to make small adjustments when trying to mesh the gear train. You will have to hold the motor onto the pinwheel shaft and guess where the best place to put the mount will be.

In both instances that I have made an LED pinwheel; I used a file or dremel to flatten the side of the pinwheel shaft that I mounted the motor to. Flattening the shaft ensures a tighter mount and makes it easier to drill holes through the plastic for fastening screws.

Next, hold all of the pieces where you think they will be mounted and use the permanent marker to draw marks on the shaft of the pinwheel where you will be placing the mounting screws. Use a drill with a very small bit to drill holes through the mounting bracket and pinwheel shaft where the motor mount will be placed.

You can use some of the screws from the vcr in order to attach the motor mount. Now, you will have to drill holes in your motor mount in order to attach the motor to it. You should also be able to use some of the screws from the VCR for attaching the motor. The next trick is to get the gear for the fan and the gear on the motor to line up so that their gears mesh. This is probably the most difficult step of the entire process. You may have to drill additional holes in the motor mount, or re-position the motor in order to get an optimal mesh.

I had to change the gears I was using at this step because I found that the differences in the gear diameters was too great to allow the pinwheel to still turn freely.

Once you believe you have the proper mesh, you will want to drill two more holes in the top of the pinwheel shaft by the location where you previously melted wires for the LED. This is in order to make holes for two screws which will be used to hold the main gear attached to the fan in place while the device is in operation. You can determine the best spot to make these holes by holding the fan gear in place and using a permanent marker to create spots on the top of the shaft for drilling.

Bend the two wires melted inside the shaft into the shape of two hooks. Also take the positive and negative terminals of the LED and bend those into hooks so that they clasp the hooks of the wires.

Wrap the wires continuously around the hooks of the LED until they are wrapped tightly. Then use a soldering iron to place solder over the LED and wire so that it is attached securely. If your LED Pinwheel isn't spinning as freely as you would like it to, don't be afraid to add lubrication to the gears. I have used WD on both of the pinwheels I have made.

The first pinwheel has been tested in a major rain storm and it ran the whole time perfectly fine. Don't be afraid to really whip these around. Both of mine have a slightly different gear train configuration, but so far they have both proved to be exceedingly durable and fun.

If you are interested in making an LED pinwheel out of something other then a VCR, make sure to visit my website Technogumbo I also have a tutorial on there for making one of these out of a broken CD-Rom drive as well as many other projects.

Have fun with your new contraption! Why not just attach the pinwheel directly to the motor shaft? It seems like the gears make the project more complicated than it needs to be.. Reply 10 years ago on Introduction. Great question! From making two of these, I don't think there is any way you could get enough push from the wind to directly attach the pinwheel to the motor shaft.

You need that gear ratio to help overcome the magnetic resistance in the motor. As it is, you really have to "whip" these around to get them to light up well. Reply 8 years ago on Introduction. What if you were to have it directly connected and were using a wind source to spin it. In an environment class we have an alternative project to make a wind turbine that produces enough electricity to power a LED instead of doing our midterm.

To test it they will be using a hairdryer as wind to see if it will work. Do you think if I directly connected it and was using a hairdryer it would power the led? I don't think so. Even if you used two gears I don't think it would do it with a hairdryer.

If you connected it directly and came up with a capacitor and diode based circuit specific to the output voltage of the motor you could maybe do it directly connected to the motor. So, the copper wires are just to get the power to the LED? The way you were describing it I was confused I thought they were to help generate power lol.

Am I correct that they're just to get power to the LED? Reply 8 years ago on Step They are just used to get power to the LED. I melted them into the plastic so that the wires don't hinder the spinning motion of the pinwheel. I started working on making a mini wind turbine last year out of a VHS recorder's heads the VCR was dead before you ask!!!

How to Make a Wind Powered LED Out of a VCR: 13 Steps

A wind turbine , or alternatively referred to as a wind energy converter , is a device that converts the wind's kinetic energy into electrical energy. Wind turbines are manufactured in a wide range of vertical and horizontal axis. The smallest turbines are used for applications such as battery charging for auxiliary power for boats or caravans or to power traffic warning signs.

Larger turbines can be used for making contributions to a domestic power supply while selling unused power back to the utility supplier via the electrical grid. Arrays of large turbines , known as wind farms , are becoming an increasingly important source of intermittent renewable energy and are used by many countries as part of a strategy to reduce their reliance on fossil fuels.

One assessment claimed that, as of [update] , wind had the "lowest relative greenhouse gas emissions, the least water consumption demands and The windwheel of Hero of Alexandria 10 AD — 70 AD marks one of the first recorded instances of wind powering a machine in history. These " Panemone " were vertical axle windmills, which had long vertical drive shafts with rectangular blades. Wind power first appeared in Europe during the Middle Ages. The first historical records of their use in England date to the 11th or 12th centuries and there are reports of German crusaders taking their windmill-making skills to Syria around Advanced wind turbines were described by Croatian inventor Fausto Veranzio.

In his book Machinae Novae he described vertical axis wind turbines with curved or V-shaped blades. The first electricity-generating wind turbine was a battery charging machine installed in July by Scottish academic James Blyth to light his holiday home in Marykirk , Scotland.

Brush was able to build the first automatically operated wind turbine after consulting local University professors and colleagues Jacob S. Gibbs and Brinsley Coleberd and successfully getting the blueprints peer-reviewed for electricity production in Cleveland, Ohio. In Denmark by , there were about windmills for mechanical loads such as pumps and mills, producing an estimated combined peak power of about 30 MW.

Around the time of World War I, American windmill makers were producing , farm windmills each year, mostly for water-pumping. By the s, wind generators for electricity were common on farms, mostly in the United States where distribution systems had not yet been installed.

In this period, high-tensile steel was cheap, and the generators were placed atop prefabricated open steel lattice towers. It was reported to have an annual capacity factor of 32 percent, not much different from current wind machines. In the autumn of , the first megawatt-class wind turbine was synchronized to a utility grid in Vermont. The Smith—Putnam wind turbine only ran for 1, hours before suffering a critical failure.

The unit was not repaired, because of a shortage of materials during the war. Despite these diverse developments, developments in fossil fuel systems almost entirely eliminated any wind turbine systems larger than supermicro size. In the early s, however, anti-nuclear protests in Denmark spurred artisan mechanics to develop microturbines of 22 kW. Organizing owners into associations and co-operatives lead to the lobbying of the government and utilities and provided incentives for larger turbines throughout the s and later.

Local activists in Germany, nascent turbine manufacturers in Spain, and large investors in the United States in the early s then lobbied for policies that stimulated the industry in those countries. It has been argued that expanding use of wind power will lead to increasing geopolitical competition over critical materials for wind turbines such as rare earth elements neodymium, praseodymium, and dysprosium.

But this perspective has been criticised for failing to recognise that most wind turbines do not use permanent magnets and for underestimating the power of economic incentives for expanded production of these minerals. It is the mean annual power available per square meter of swept area of a turbine, and is calculated for different heights above ground.

Calculation of wind power density includes the effect of wind velocity and air density. Wind turbines are classified by the wind speed they are designed for, from class I to class III, with A to C referring to the turbulence intensity of the wind. Conservation of mass requires that the amount of air entering and exiting a turbine must be equal.

If the effective area of the disk is A, and the wind velocity v, the maximum theoretical power output P is:. Wind-to-rotor efficiency including rotor blade friction and drag are among the factors affecting the final price of wind power.

To protect components from undue wear, extracted power is held constant above the rated operating speed as theoretical power increases at the cube of wind speed, further reducing theoretical efficiency. Efficiency can decrease slightly over time, one of the main reasons being dust and insect carcasses on the blades which alters the aerodynamic profile and essentially reduces the lift to drag ratio of the airfoil.

Analysis of wind turbines older than 10 years in Denmark showed that half of the turbines had no decrease, while the other half saw a production decrease of 1. This is due to a faster recovery wake and greater flow entrainment that occur in conditions of higher atmospheric stability. However, wind turbine wakes have been found to recover faster under unstable atmospheric conditions as opposed to a stable environment.

Different materials have been found to have varying effects on the efficiency of wind turbines. When tested, the results showed that the materials with higher overall masses had a greater friction moment and thus a lower power coefficient. Wind turbines can rotate about either a horizontal or a vertical axis, the former being both older and more common.

Large three-bladed horizontal-axis wind turbines HAWT with the blades upwind of the tower produce the overwhelming majority of wind power in the world today. These turbines have the main rotor shaft and electrical generator at the top of a tower, and must be pointed into the wind.

Small turbines are pointed by a simple wind vane , while large turbines generally use a wind sensor coupled with a yaw system. Most have a gearbox, which turns the slow rotation of the blades into a quicker rotation that is more suitable to drive an electrical generator. These don't need a gearbox and are called direct-drive, meaning they couple the rotor directly to the generator with no gearbox in between.

While permanent magnet direct-drive generators can be more costly due to the rare earth materials required, these gearless turbines are sometimes preferred over gearbox generators because they "eliminate the gear-speed increaser, which is susceptible to significant accumulated fatigue torque loading, related reliability issues, and maintenance costs. Most horizontal axis turbines have their rotors upwind of the supporting tower.

Downwind machines have been built, because they don't need an additional mechanism for keeping them in line with the wind. In high winds, the blades can also be allowed to bend, which reduces their swept area and thus their wind resistance. Despite these advantages, upwind designs are preferred, because the change in loading from the wind as each blade passes behind the supporting tower can cause damage to the turbine.

Turbines used in wind farms for commercial production of electric power are usually three-bladed. These have low torque ripple , which contributes to good reliability. The size and height of turbines increase year by year. Designs with 10 to 12 MW are in preparation. Vertical-axis wind turbines or VAWTs have the main rotor shaft arranged vertically. One advantage of this arrangement is that the turbine does not need to be pointed into the wind to be effective, which is an advantage on a site where the wind direction is highly variable.

It is also an advantage when the turbine is integrated into a building because it is inherently less steerable. Also, the generator and gearbox can be placed near the ground, using a direct drive from the rotor assembly to the ground-based gearbox, improving accessibility for maintenance.

However, these designs produce much less energy averaged over time, which is a major drawback. The key disadvantages include the relatively low rotational speed with the consequential higher torque and hence higher cost of the drive train, the inherently lower power coefficient , the degree rotation of the aerofoil within the wind flow during each cycle and hence the highly dynamic loading on the blade, the pulsating torque generated by some rotor designs on the drive train, and the difficulty of modelling the wind flow accurately and hence the challenges of analysing and designing the rotor prior to fabricating a prototype.

When a turbine is mounted on a rooftop the building generally redirects wind over the roof and this can double the wind speed at the turbine. While wind speeds within the built environment are generally much lower than at exposed rural sites, [35] [36] noise may be a concern and an existing structure may not adequately resist the additional stress.

They also generally require some external power source, or an additional Savonius rotor to start turning, because the starting torque is very low. The torque ripple is reduced by using three or more blades, which results in greater solidity of the rotor.

Solidity is measured by blade area divided by the rotor area. Newer Darrieus type turbines are not held up by guy-wires but have an external superstructure connected to the top bearing. A subtype of Darrieus turbine with straight, as opposed to curved, blades. The cycloturbine variety has variable pitch to reduce the torque pulsation and is self-starting. Straight, V, or curved blades may be used. These are drag-type devices with two or more scoops that are used in anemometers, Flettner vents commonly seen on bus and van roofs , and in some high-reliability low-efficiency power turbines.

They are always self-starting if there are at least three scoops. Twisted Savonius is a modified savonius, with long helical scoops to provide smooth torque.

This is often used as a rooftop wind turbine and has even been adapted for ships. The parallel turbine is similar to the crossflow fan or centrifugal fan. It uses the ground effect. Vertical axis turbines of this type have been tried for many years: a unit producing 10 kW was built by Israeli wind pioneer Bruce Brill in the s. Wind turbine design is a careful balance of cost, energy output, and fatigue life.

These factors are balanced using a range of computer modelling techniques. Wind turbines convert wind energy to electrical energy for distribution. Conventional horizontal axis turbines can be divided into three components:. Due to data transmission problems, structural health monitoring of wind turbines is usually performed using several accelerometers and strain gages attached to the nacelle to monitor the gearbox and equipment. Currently, digital image correlation and stereophotogrammetry are used to measure dynamics of wind turbine blades.

These methods usually measure displacement and strain to identify location of defects. Dynamic characteristics of non-rotating wind turbines have been measured using digital image correlation and photogrammetry. Wind turbine rotor blades are being made longer to increase efficiency. This requires them to be stiff, strong, light and resistant to fatigue.

Companies seek ways to draw greater efficiency from their designs. A predominant way has been to increase blade length and thus rotor diameter. Retrofitting existing turbines with larger blades reduces the work and risks of redesigning the system. The current longest blade is Longer blades need to be stiffer to avoid deflection, which requires materials with higher stiffness-to-weight ratio.

Because the blades need to function over a million load cycles over a period of 20—25 years, the fatigue of the blade materials is also critical. The stiffness of composites is determined by the stiffness of fibers and their volume content. Typically, E-glass fibers are used as main reinforcement in the composites. This increases the stiffness, tensile and compression strength. A promising composite material is glass fiber with modified compositions like S-glass, R-glass etc.
