    • How to Generate Alternative Offgrid Power by building a Homemade Waterwheel Hydro Electric System
      This project goes into the build of a homemade alternative offgrid power generation system using a water wheel and flowing water source like a stream or creek. In order to catch the water from your spring or creek , the first step is to build a small dam. This enables us to produce maximum power from the running water wheel . First, We use a 4 inch pipe to divert the water before starting the construction of the dam. With a solid concrete foundation ,we aim to make a 42 inch dam with 30 inch of head . A six inch 36 inches long PVC drain pipe is installed on the high water side .The dam is constructed using four layer of hollow blocks and quickrete blended mason mix .Try raising the water higher to see how much higher it needs to go before it overflow through the sides. The dam board gates made of deck boards are installed in the middle .The back board and the front boards are spaced apart an inch and three quarters. The dam stop gate made of plywood with dimensions of one and half is inserted between the boards . To get a tight seal a half inch rubber tube is stuffed between these boards. With a 13 and half inch treated plywood and couple of 2X6 plywood side boards, the flume is built. The side boards are glued to the plywood base using adhesive sealant and screwed with exterior grade screws. To resist twisting and to keep the width of the plywood steady , four cross spacers are installed on the flume board. To divert the water without having to drain the dam, we make a small trap door in the flume near the opening . The trap door is made seven inches back from the face of the dam. The door is supported by a flange around the back and a stainless steel hinge. The flume is installed on the creek with the help of rebars and supporting deck boards. The rebars are attached to the boards using u-bolts and drill bit. Three more subsequent flumes are attached to each other. The gap between the flumes are sealed with poly foam caulk rope. The waterwheel is made out of a section of 55 gallon HDPE drum . The blades are made of 4 inch PVC drain pipe. The blades are curved so that it retains most of the water making it more energy efficient. 24 blades are attached to the drum using 16th by half aluminum angle pieces. A three quarter inch jack shaft from an old go-kart is used as the drive shaft. This is supported at both ends of the wheel with a help of pillow block bearings. Two 28 inch Circular end pieces made of plywood is bolted along both sides of the barrel using a 6 ten inch long half by thirteen carriage bolts to make the wheel build complete. Two square collar blocks are mounted on to shaft to center them. The holes are larger than the shaft so that the wheel can be adjusted to get the runouts reduced.To center the waterwheel and to adjust the runout of the center shaft , we use four blocks and adjustment bolts around the center block like a four jaw chuck . To install the water wheel securely, a support structure made of 2x4 boards are installed near the end of the flume. The water wheel is secured on these support boards with the help of couple of swivel block bearings. We use an adjustable Unistrut to mount the bearings,sprockets and the motor. This can be adjusted for chain tension as well. The Unistrut will stand vertically on top of the cross support that is under the flume.The Unistrut's are mounted onto the wheel on both the sides with help of bearings and T-nuts. A Number 35 sprocket with 72 tooth is mounted onto the center wheel shaft. This sprocket is connected to a half shaft with 11 tooth sprocket with the help of a size 35 go kart roller chain. A Permanent Magnet Brushed DC motor mounted on 2x4 board is further connected to this shaft via another sprocket. This gear system has a ratio of 30.86:1 Using unistruct angled brackets, the wheel is mounted onto the support board near the flume. The wheel is positioned near the flume in such a way that the water where it meets the wheel is exactly at the top. The charging system consists of a 12V DC emergency standby battery, MPPT charge controller, 300W sine wave inverter . The connection from the water wheel DC motor goes to the charge controller.The charge controller is also connected to the battery. Finally the inverter is connected to the battery which is further connected to a load. To make this charging system secure, make sure to make fuse connection between the components. All these components are mounted on a temporary wooden board. https://www.youtube.com/playlist?list=PLDda5L4aJUB-IuU3SWstKewFvzfv3wJGI
    • How to make a Survival Rope Making Machine at home from easily available materials
      This project goes over the build of a Homemade rope making machine using a simple cordless power drill and some inexpensive materials that are sourced from the local hardware store. Here are the materials needed for this project: Three quarter inch by five inch eye bolts with hex nuts Fender Washers Cut Washers Hex Nuts Plastic Castor Wheels two by two and one by six by six piece of lumber Old bicycle tire tubes Take the board and cut it to length of seven and a half inches and took the first piece and doubled it over the second one and cut them together so that they are exactly the same length. Then I took a piece of two by two and cut it eight and a half inches long. Take large fender washers and position them on the board forming a triangle, you want to do it in such a way so when you add your two by two to the top as well as the bottom, it has similar spacing at the top and the bottom. Put the two boards together, mark the centers and drill the holes. Next step is to build the metal spinning hooks. These spinning hooks are going to be made out of eyebolts which is used as a hook to put the strings on. We take 3 plastic castor wheels and use them as a pulley , connect them together with a small piece of bicycle tire tube so that when one is spun ,all three of them would spin together. We take the 3 eyebolts and push it through the hole and secure them tight with a small cut washer and hex nut. It is locked in place but should spin freely. Put with wheels through the bolts and secure them using fender washers, cut washers and nuts. Take an old used tire tube piece and line it up between the two washers and cut up a piece that is roughly about the same distance as that gap. We loop the tube over the pulley all at once.The Second board is pushed through the bolts over the wheel pulleys.Make sure everything is lined up symmetrically. When we turn one bolt, the belt drives the other two pulleys and they all spin together. As we are running the hook spinner, we are going to need something to hold it at the other end, To make the other end of the mechanism that holds the strings in place, we take six inch piece of common board and eight and a half inches of our two by twos on the bottom to secure it as a base and them we clamp it over a table. The idea is that as each hook begins to spin, the two cords attached to it will intertwine with each other. And then eventually all three of those cords will mesh together to make a nice three stranded rope. As the strands are twisted, it creates tension on the backboard. To relieve the tension, we drill a hole through the backboard and tie the rope to another counterweight rope through a swivel hook that pulls the tension and allows it to rise as the cord is pulled. We also make a rope makers top that will help guide those strands into the beautiful three strand cord. We add two ropes between the spinner mechanism as guidelines and connect it to the back board to accommodate the rope makers top. The idea is that as the tension builds it will glide forward and guide the individual strands into place to form a three stranded rope. We sandpaper the holes on the rope makers top to make it smoother so that the lines won't snag up when they start twisting. We put a wooden knob on the back to reduce the friction so that the rope makers top can slide smoothly. Loop the cords through each of the three hooks on our rope maker machine .Form a slipknot and connect it to the swivel hook. We have our rope machine build complete . To tie and cut of the rope, take a small piece of electrical tape and wrap it around the end where you want to cut it off. Cut The Rope at the back just where the electrical tape ends . https://www.youtube.com/watch?v=ddenqErLL0Q https://www.youtube.com/watch?v=uEvM6ue3L7E https://www.youtube.com/watch?v=RM9GY-n6PEA
    • DIY Video:How To Turn Your Old Fan Into An Airconditioner AC for cheap.
      This project shows you how can take an old table fan and convert it into a simple ,cheap and easy to make homemade AC . The materials needed for the this project are a table fan, 75 gallon per hour fountain pump with valve to control the water flow, multi purpose zip ties ,two 3/8th inch transparent PVC Pipe tube, 15 foot quarter inch copper tube,two hose clamps. Unhook the locks if any and remove the screen of the fan. Take the copper coil and wind them across the rims of the fan .Secure them tight on the screen using multi purpose ties. Add the screen back to the fan body and then adjust the two ends of the copper coil by bending them to face the back of the fan and secure them using ties. Two 3/8 transparent vinyl PVC pipes are connected to the copper tube ends using hose clamps. We attach the fountain pump to the end of the vinyl PVC tube that goes straight into our cooler. The recirculated water coming from the other end of the tube goes straight back into the cooler bag. The cooler bag is filled with ice packs and water. The water pump is submerged into the bottom of the bag with ice and water over it. The water which is pumped with the help of the fountain pump gets recycled through the vinyl and the copper pipe and moves back into the bag, so you dont need to add more water .Both the pump and fan can be connected to solar generator in case if you want to make the system portable . https://www.youtube.com/watch?v=5NuvzWaBulw
