This project goes over the build of a homemade wind generator built from random junk ceiling fan ,microwave oven transformer ,office chair, an old piece of a TV tower, and some random electrical stuff. The blades are also from an old ceiling fan .It is extended with some wood and fibreglass on it to make it stronger.
A scrap piece of pipe is attached as a shaft to the hub of the turbine. An office chair frame which can move freely is welded to the pole/post of the turbine. This is welded to an old TV Tower.
4 magnets are glued on the hub. The frame of an old microwave oven transformer is cut .Its core is exposed and that is welded onto the brackets. The magnets pass over the transformer core and induction takes place creating electric current. We can use that current to charge a battery or to power lights or whatever. A multi transformer setup would generate more power.
We hook up a rectifying diode to convert from AC to DC and some capacitors which can even out the voltage and give us direct current. Also a diode to block the current from the battery to go up back up to the generator. This set up can charge small batteries.
A piece of sheet metal is welded onto the bracket of the ceiling fan. Four magnets are spaced apart and aligned along their respective poles in north-south directions and glued to the bracket using 2 part epoxy.
To generate more wattage from the wind generator ,we use an old 120V DC lawnmower motor. Because we have multiple poles, we have magnets that are really close to the armature, this is a way better motor to use. The only downfall of this is that it has brushes, eventually it’s the brushes are going to wear out, you probably get a few years out of it before you need to replace those. This motor would probably put out about 100 watts.

- DIY Video :How to build a Simple and Efficient Copper Coil Burner Stove from start to finish.Great in a emergency/disaster or while out campingThis project goes over the build of an simple and efficient copper coil tiny alcohol burner jet stove. The materials you need to make this stove are canning jar, small copper tubing, JB weld to seal up the from inside and outside , pipe to wrap the coil, couple of drill bits, a wick material, sand and Isopropyl Rubbing Alcohol as a the fuel. Fill the copper tubing with sand all the way up. Seal both ends of the tube with a cloth or a cap. With the help of a vice ,we bend the tubing around the pipe into a loop. Flatten the sides of the coil keeping the sides together. Empty the sand out of the copper coil and run water through it to get everything out. This is done so that the inside is completely open for the air and the gas to build up and burn in there. Cut a vent hole down the center of the looped coil using the smallest drill bit. Mark the canning glass jar against the copper coil so that we can cut off the extra coil legs so that the coil fits inside the jar approximately three quarters way down. Next step is to make holes for the lid of the jar . Place the coil on top of the lid and make two spots for the holes. We use a drill bit ,same size as the coil to drill two holes. The coil is placed through the two holes of the lid and sealed on both the top and bottom side using JB Weld. Allow the glue to set for an hour. Take your wick cloth material ,insert and twist them through both the holes of the coil all the way up to the top. Pour some Isopropyl Rubbing Alcohol onto the jar , place the lid with the coil on the top and tightly close the jar with the cap. Wipe the sides of the coil with rubbing alcohol. To prime the stove for its first burn , start by heating the coil using a propane torch first. The heating of the coil gets the gas going. Heat until the flame starts to appear. Burn for four to five minutes to steady the flame. https://www.youtube.com/watch?v=HFrWw5dgliQ
