How to build a Homemade Micro Wind Turbine for under $50 that can be mounted anywhere

    This project goes in the detail on how to build a mini wind turbine..The wind turbine is a nice addition to your solar generator system for times when it’s cloudy and you are not receiving as much sunlight as you normally

    First step is to build some cheap PVC blades, what kind of motor we’re going to be using and how we’re going to attach this to the motor.
    We are making six blades or rotors here.What we want to do is we want to cut our PVC pipe to length first.

    Once you’ve got it cut to length, then you want to take your your straight edge again and and Marco line down the center and cut it in half. Make sure that you do that on both sides. One on this side, one on this side. And that they’re perfectly in the middle so that you’ll get two even sides.

    We need to cut a small little block down at the blade end, where we are going to put a drill hole and put a screw through it so that it attaches to the hub.On the top of the blade, we’re going to cut away some of the material to resemble a swept wing, kind of at an angle.

    These are 14 inch long blades that is attached to the hub using set screws attached to the motor. The 12V motor used here is a 300 RPM geared motor which would be its maximum speed and it produces 600 milliamps when its fully loaded.

    The motor is placed inside a One and half inch PVC pipe ,another PVC Tee is connected from where the wires will down to the bottom where another 7 foot pipe that act as the tower or pole.

    The end of the pole goes into a shower drain which is then attached to piece of wood that acts a solid base.

    For the YAW system at the back end,a tail vane is made of a cheap flashing material that is bolted between an 8 inch piece of PVC.Put a hole through the middle of it with a bolt in between so that it can’t move anywhere.

    We use an an old OSB for the base, size is about seven inches square. And then I just have a piece of treated lumber on the bottom. It’s attached to this ball bearings so it can spin around. The Shower drain PVC is placed in the middle through some ball bearings. Route the wiring down through the hole for to connect to the charge controller.

    Next step is the wiring through the piping.We just need to connect these terminals to the appropriate sides of the motor.

    • How to convert an Old Ceiling Fan Motor into a 70W Efficient Single Phase Alternator Generator
      This project goes over the conversion of an old ceiling fan motor into an single phase alternator .You can't take your standard AC electric motor and spin it and get an electrical current out of it unless you modify it. The ceiling fan motor used here will produce about 70 volts at one amp which is roughly 70 watts. Through a bridge rectifier we can get about 70 watts of power out of it. We start by pulling the cover of the fan. Inside we have a squirrel cage rotor in the middle and 6 coil windings around it. The coil windings are placed in clockwise and anti-clock wise directions inside the stator. Next we remove the circular rotor from the threaded shaft which is attached to it with help of a vice. We attach the shaft with the rotor through it within a vice. With the help of an extra piece of pipe to give leverage, we press them against the rotor and push it away from the rod and pop it off. We are replacing the rotor that we have detached from the shaft with a two inch hex steel bar . It has six sides that matches with the six coils from the stator. With the help of one eighth inch drill bit we cut a hole in the center of our hex bar. We put the hex bar through the shaft and fit them snugly around the threaded area. We take six one half inch neodymium or rare earth magnets and place them along the the 6 sides of the hex bar. We place them in such a manner that the poles of the magnets are opposing each other. For permanent usage, wrap this with a little bit of tape or glue so that they are held in place securely. We place our modified rotor in the middle of the stator and align them such that they fit in tightly. The outer screen is bolted back onto the motor. We can also add second set of magnets to increase the magnetic field of the rotor .This will also bring it closer to the coils on the outside and increase the overall voltage. To convert the alternating current generated by our ceiling fan alternator to direct current, we use a bridge rectifier. It has 4 poles, 2 for connecting our alternating current, the other plus and negative for DC power.
    • DIY Video:How to build an awesome Roof Top Portable ABS Pipe Hot Water Heater/Shower . Great for Camping/ Outdoors
      This project goes into the build of a DIY solar powered pressurized roof top water heater and shower that is portable for outdoor survival and camping trips. This project is easy to make and requires only minimal tools and plumbing parts. The dimension of the pipe used for this build is six feet tall and four inch wide. This has a capacity of 15 liters. The materials you need to build this project are six feet long four inch ABS pipe, air compressor, two four inch PVC end caps, abs cement, rubber schrader valve, shutdown valve and retainer nut, radiator valve drain plug , forstner bit,two inch threaded end cap, high heat flat black paint, steel wool scrubber, methyl hydrate. The shutoff valve is installed as low as possible in the pipe to avoid the necessity of having to tilt the system. Mark the position for the valve keeping the retainer nut in place , we insert a forstner bit into the nut creating a center mark for the drill .Once the hole is drilled ,we thread the shut off valve into place and attach the retaining nut. For installing air compressor for pressurizing the tank ,we use an long schrader valve that is used for aluminum rim tyres. This valve uses threaded nuts to secure it in place . Next step is to install the water intake opening. For this we use a two inch PVC threaded adapter socket . We take the diameter of the fitting and then drill out the opening and glue the fitting in place using ABS solvent cement. A radiator valve drain plug is installed on the threaded end cap of the water intake PVC fitting .This valve helps to release extra pressure from the tank without opening the main drain shut off. In order to improve thermal absorption of solar energy, the surface of the ABS pipe is painted with flat black paint. The surface is polished with steel wool soaked in methyl hydrate and applied one coat of spray primer followed by two coats of high heat restoleum black paint. To mount the shower to roof of the car or truck , we use a canoe foam block . We extend the slots in the foam block to make them fit inside the cross rails . An arc is cut on the foam block equal to the outside diameter of the pipe and positioned it such that it left half an inch of foam between the mounting slot and the bottom of the arc. To attach the shower to the support pads, here we use one inch nylon tie down straps. With both these pads in place, the water heater is securely attached to the roof. An inexpensive 25 foot long coiled three eighths inch hose from the local garden center is used as the shower hose. This would be perfect as it is easily stored and can be taken apart after use. The air compressor is connected to the pipe with the help of a multifunction spray nozzle . Thee bursting point of six inch ABS pipe is well over 100 psi .So a 30 psi would provide safe and ample pressurized shower without any long term expansion fatigue to the pipe or glue connections .
    • DIY Video : How to build a Simple Homemade PVC Wind Turbine Generator with Swivel Top .Produces electricity to run lights, charge batteries
      This project goes into the build of a DIY swivel top wind turbine generator that can generate off the grid electric power to run lights, radios, charge batteries. This durable, lightweight and portable wind turbine would be very useful in SHTF / Power outage / Emergency situations. The materials you need to build this wind turbine are as follows. 3/4th inch PVC pipes including 5 90 degree couplers, 3 Tee couplers,4 Three and half inch pipe, Two 8 inch pipe, Two 3 inch pipe and long 11 inch pipe for the post. The propeller for the turbine is made from a 5 gallon bucket lid or you can buy them from your local hobby store, 3V 350ma DC hobby motor, wire from an old extension cord. The base stand for the turbine is assembled using the PVC couplers and the tee's. The 11 inch PVC post pipe is finally attached at the center of the support base. Use PVC pipe cement to strengthen the connection between the joints. Next step is to make a hole at the bottom of the post for the electrical cord . A hole is drilled one inch from the end of the PVC pipe. The wires from a broken extension cord is used for this project. The wires are soldered to the ends of the motor first for a good tight connection. The wire is fed through the pipe and the motor is mounted at the top . A duct tape is wrapped around the motor multiple times so that it fits the entrance of the pipe opening. Before encasing the motor, the blade is put on . To build the swivel assembly ,we need a PVC union, an adapter, 3 inch pipe. The adapter is screwed on to the union, the 3 inch pipe is then connected to the adapter. The tail fins are made from an old waste basket. The fins are screwed on the post using machine screws. To stop the post from rotating 180 degree in both directions, we put couple of screws on either direction on the side of the post in such a way that it prevents the post from rotating 180 degree . Not only you can charge your batteries using this set , but this can be connected to an inverter to run AC powered appliances.
