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 .
- How to build a Multi Use Simple Homemade Wood Gas System from Scrap Materials that can be used as a Generator,Cooking Stove and LanternThis project goes over the build of a simple gasification system that functions to produce wood gas for running a generator, a cooking stove and for lanterns. We feed the wood chips and other materials through the opening at the top of the gasifier ,the air also gets drawn in from the top .The air would drop through the wood mass, down to the reduction zone and gets collected down at the bottom of the tank through the output pipe . The materials needed to build this down draft style gasifier are a 3 old propane tanks, old steel sheets, wood pellets. The first step is to make sure that propane tanks are empty .Remove the handles from the top of the 3 propane tanks and unthread the valves. Cut the top portion from 2 tanks and stack the body of the tanks on top of each other and weld it. One of the cut out top pieces can be used a lid . The bottom portion of the lower tank is cut open to create the reduction zone of the gasifier. To make the reduction point, we take the scrap steel sheet and make a five inch wide small tube of the them and weld them to the bottom third propane tank . The bottom five gallon propane tank is used as a ash bin where all the ash is going to get caught and as an outlet for all the gases coming out of the system. The top portion of this tank is cut in such a way that it fits the reduction zone collar of the secondary tank. Make sure that both the tanks fits nicely together so that you can pull the inner chamber out of the bottom ash tank to remove it, dump the ash catch out and use it again and again. The top of the upper tank is cut open .This acts as the feed area where all the wood pieces are dropped in. We make a screen with holes using a 20mm hole saw cutter from the leftover cutouts of the propane tank. We are gonna mount this screen inside the gasifier lower reduction zone. A hinge and a wire is attached to the screen so it can open and close. This gives us the ability so we can shake the screen if it plugs up with ash or other materials. The wire goes through the reactor up to the top . We have a pressure relief system installed on the lid of the gasifier. If anything were to happen inside of the gasifier , the build up pressure can be made to escape through the top lid .This is done by hooking up two springs on both sides of the lid through small loops .The springs on both sides is attached to hand levers. We drill 8 half inch diameter holes just above reduction zone area and put thick steel tubing through them to the center of the chamber. The airflow will go in and be drawn down through the center of the reduction zone that helps in efficient burn. The pipes are curved in to the chamber so that it does not interfere with any wood mass as it goes into the reduction zone. We add plugs along these 8 tubes to regulate the air flow into the system. Next step is to add the draw fan to the gasifier. Here we use a pellet stove fan .We add a 2 inch plate over the face of the fan and a threaded pipe to seal any air going into the gasifier. We start up the gasifier by putting some chopped wood through the top and use the fan to get the wood gas producing out of the bottom outlet pipe. https://www.youtube.com/watch?v=h9vuphZe8iU
- DIY Video :How to build your own Homemade Lumber Mill from Scratch .This projects goes over the build of a cheap homemade lumber mill using materials around your home This mill has a 12 inch saw blade purchased from Home Depot that cab do cross cuts, or it can do longitudinal rip cut.I am gonna be cutting the long direction on the word. First step is building the rollers. Four rollers are made out scrap materials lying around. The wheels are made of polycarbonate material .These are adjusted on a drill to ensure that they roll smoothly on the pipes. Next step is the build the tracks.Here I use 2 old steel pipes and welded to make a long one. 3 more pipes are welded on top of those 2 long pipes horizontally to give stability. Make sure the pipes are all lined up . 2 rolling carts are made from the leftover pipes tha slides across the pipes.Make sure these are parallel to each other.4 sliding pipes are bolted on these carts. 4 pieces of pipes are welded on top of these rolling pipes that are paralled to the horizontal pipes below .They act as a crank that can pull the sliding pipes. Threaded holes are put along the pipe that connects the sliding pipes.2 cables are connected in opposite ways to a small spring pulley system that can help sliding pipes move vertically up and down when the top crank is rotated. The Saw Blade is attached to a steel rod.The blade is attached to a washer on the other side to ensure it doesn't fly off. The axle is passed through a square metal box which is bolted using a bearing on both sides. The motors attaches to the top of the box mount .A pulley is then attached to the metal rod from the motor using a small wheel. The next step is to take whole side assembly thing attach it to the cart so it can pivot. Ball bearings are attached to the box on both sides.This must be placed at a very specific distance away from the blade. So that when I flip it the the edge of the blade will line up so it cuts clean without cutting deeper into the wood and without not cutting far enough and leaving it still attached.When its swiveled it will pivot the blade perfectly. Next step is make take the whole motor and blade assembly and attach it to our rails so that it can slide and rotate . We attached 2 pieces on both sides of the motor blade assembly to ensure that the system stays perfectly straight while cutting horizontal or vertical. https://www.youtube.com/watch?v=KtL7LoFeTyg https://www.youtube.com/watch?v=txUgR7kYpgI https://www.youtube.com/watch?v=LUxo36NebVA https://www.youtube.com/watch?v=IOEHT1UrbKM https://www.youtube.com/watch?v=deblj68KZug https://www.youtube.com/watch?v=Axo2w5_qHd8 https://www.youtube.com/watch?v=_uhvSBLY0Xc https://www.youtube.com/watch?v=5sPu_TcUtyU
