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.
- How to build a Homemade Chainsaw Mill from Scratch. Step by step Build InstructionsThis project goes over the build of a simple and basic DIY chainsaw mill from start to finish. This chainsaw mill is portable and doesn't require very large space . This is a very inexpensive way of producing lumber from logs and can be made from easily available materials from your local hardware store. The materials you need to build this chainsaw mill are one by one square tubing, half inch square tubing, quarter inch flat bar, weld nuts, bandsaw and welding unit. The welder used here is Millermatic 212 auto set mig welder and the saw is Homelite 1130g The dimensions of the saw are as follows. A 12 inch deck to slide across the log that acts as a milling surface. The max width of the mill is 26 inch. An 8 inch metal to grab the bandsaw on both the sides. A quarter inch flat stocks for the holding the saw. We start by cutting 26 inch pieces for the sides and 12 inch pieces for the sides. Assemble them into a rectangle and weld it using a MiG welder. Do Check if the corners to make sure it is square and the sides are even. A center bar welded into the rectangular guide plate, just to give it a little bit more support and make it so that it doesn't twist. Two guide posts are welded onto the sides. 2 larger pipe sections of dimension one by one is cut .This will slide within the guide posts. This is done so as to make the saw adjustable to how thick it cuts a slab .The side posts also gives you adjustability on the deck to move up and down. 4 quarter inch flat bars of length nine inches are cut . Two of them are bolted onto bottom section of the rails that slides up and down on the guide posts . The saw blade is placed securely between these bars. A small spacer block is welded onto the bars so that it doesn't touch the saw blade. Three eighth inch weld nuts are welded onto the side posts . Tightening with the bolts locks the adjustable rails in place. A crossbar is welded onto the guide posts .These help push the bar along when you are operating the mill and it is a nice place to put your hand , It feels like you are farther away from the chain. The chain saw blade is inserted between the flat brackets at the bottom and it is locked tight in place between the spacers using 3/8th inch bolts. For the first cut, we attach a flat plate at the top of the log so that the bar has something to ride. The height of the cut is adjusted with the help of the side rails on the mill . The saw is then started and placed on top of the flat plate to begin cutting the log. https://www.youtube.com/watch?v=DA-HknSaBvI
- How to build an DIY 12 V Portable Water Pump Box with filtration system for Outdoor Survival / RVThis project goes into the build of an offgrid portable water pump and filtration system that can turn any water from your creek,lake,river into safe and clean drinking water . This 12V portable system can be powered by solar or from your car directly and is ideal for camping , RV or outdoor survival enthusiasts. This system enables them to pump water from a fresh water source, filter and then store or use in case of emergency survival situation. The materials you need to build this portable filtration system are as follows. A tactix storage box to lodge the water pump,inlet and outlet hoses, an inline water filter or twin carbon 0.5micron filter, pex pipe, garden hose pipes, 12mill barb strainer,rocker switch ,12V Shurflo water pump with the flow rate of 11 litres per minute, 50 amp Anderson plug and 10m heavy duty wire ,basic tools such as wire cutters, long nose pliers, solder. The first step is completing the wiring for the water pump inside the tactix tool box. The rocker switch , the Anderson plug and a 7.5 Amp inline fuse are wired. The 12V rocker toggle switch is mounted at the center of the box lid. The power input plug or the Anderson plug is mounted to the left of the switch. This input plug connects to the car battery or a solar battery. The positive red wires from the switch is connected to the Anderson plug through an inline fuse .The negative black wire from the plug goes straight to the switch. The remaining wires from the switch is then connected to the water pump which will be installed later. The wires are covered with corrugated split tubing to ensure that it is protected and safe. The filter strainer is installed on the inlet side of the pump using an elbow, thread tapes. The strainer will filter out any unwanted debris before it goes to the pump. Couple of holes are drilled into to the side of the box where the inlet and the outlet hoses will connect the water pump. The male fitting are attached to the holes before the pump is installed. The pump is placed inside the box and mounted securely in such a way that the elbows are facing towards the two holes for the exterior hoses that was just made at the side of the box. Once the pump is mounted ,we connect the red and black wires coming from the switch to the positive and negative connections of the pump. The wires are once again covered with corrugated split tubing for safety. To connect the pump with the hose outlets , we measure the distance between the outlets and the pump and connect two pex pipes . Heat was applied to the pipe for bending and moulding them to connect the outlets. The 10 metre 50 Amp Anderson plug extension heavy duty cable wire is connected to the power source .Here the power draw is from a car battery. The other end is connected the input anderson plug on the top side of the box. The inlet hose with the strainer attached is placed sitting midway into the water source .The other end of the hose is connected to the intake pipe coming from the pump inside the box. The The other hose is connected to the outlet pipe coming from the water pump inside the box. At the end of the hose , we connect an inline water filter or a twin carbon filter . The carbon filter ensures that there is no sediments or debris inside the water and also helps to eliminate bacteria and other contaminants. https://www.youtube.com/watch?v=bLiTn8YacWo
- How to build your own 24 X 24 Garage and save money. Step by Step Build InstructionsThis tutorial goes over the basic overview of a 24x24 , two 9 foot door,one side door window garage.First of all,you will need to take permission from the building inspector.The inspector makes sure that you are within zoning requirements.You will need the paperwork ,plot plan when you go to the building inspector and those are available from your assessor's office or the town hall or you may have one with your deed.Started with a bucket loader come in, take out some trees level off the area remove blushes and prep for the concrete work. The first step is to dig down and install the footings where the wall is kind of set.Here I have a four foot wall put in with the floating floor. Wall of the foundation is about six inches high, it goes into the ground four foot.And one reason that I wanted the wall foundation versus a flat pad foundation is because of the bug issues. After the footings are dry in a few days,the walls are put up and I have the openings for the two nine foot doors and a side door. After they dry for a few days,the floor screen is laid .This is a standard 4 inch thick flooring. Floating floor means that in reality, if the ground swells during the winter time, the floor can actually rise up and sink down. But it prevents it from cracking because it does have a little give to it. So it's not actually connected to this wall. It's poured right up against it, but the floor is a separate piece by itself. When the walls are poured every four foot they have a half inch threaded rod that's embedded into the concrete while it's still wet, it goes down about maybe a foot and a half has an L shape on the bottom in the rod will stick up directly in the center of the 2 X 4. 2 inlets for underground wiring,a 50 and 130 amp circuit.Its buried four foot down through the PVC. The walls are standard 2 X 4, a double sill plate and a top plate those are the two that run horizontally. I use pressure treated against the concrete which will take care of the bug issues. The headers for the garage door is standrd 2X10,double up half inch plywood in the center. The plywood on the three sides and trusses are put up.The trusses are put upside down and they are flipped up.But once they're up there I marked the top sills where I wanted them nailed them and put braces across the top,measure and straighten them out. The first truss on the end of the building on both ends is called the gable end. It's a little different than the other main trusses.The trusses are 24 inch on center, which means that they're spaced 24 inches apart,unlike the walls which are 16. The roof and the sides are on half inch plywood.I also run some stringers down the center and off to the sides to help so they won't twist during a snowstorm.One thing that's very important is when you put up the plywood the very first piece that you put on is the most important piece of wood that you're going to put on this garage because everything references off that one piece.It has to be square to the gable end . When the first piece of plywood is put up, you install the plywood ties between the trusses and all that does is if the roof gets moisture from inside the garage,it will tend to flex.The ties help in keeping them nice and flat and avoid the bowing. The truss catwalk goes right down the center that stabilizes the horizontal bottom piece of the truss. The doors are framed and roof is made of standard architectural shingles.These shingles have more lifespan.Also added tarpaper on the roof.The wiring is through down the center of the catwalk.
