DIY Video: How to build a Homemade Hot Water Off grid Air Heater using Heat Exchanger and a Car Radiator Fan

    This video shows the build of a Homemade Hot Water Air Heater using an old heat exchanger and a car radiator fan.This unit provides near-instant warm air.The Air-Flow: it’s adjustable from 10 CFM to 1500 CFM. max breeze 20 Mph! The Temps: With input water temps between 120F to 150F the output air temp ranged from 85F to 110F. *or from heat pump temps up to near furnace temps! easily warms a room or two, maybe more.The heart of the unit is an 8×8 Copper/Aluminum Heat Exchanger., This unit can easily be run straight from a 12v solar panel or battery so it’s “off-grid” ready. Simply mounted the fan in front of it,then connected the pipes. then you just connect a small water pump (200-350 gph) to one of the pipes and drop both pipes into a water-filled sink,almost immediately it creates very warm air (in under a minute).

    • DIY Video : How to build a DIY Pex Coil Solar Thermal Water Heater. Simple and Efficient!!
      This video shows the build of a Simple Pex Coil Solar Thermal Water Heater.asy DIY! No Soldering, Clamps, Crimp Rings, Glues, Unions, or that expensive crimping tool! in my design it's just 2 push-to-fit "shark-bite" connectors! (located outside of collector) and because it's all one piece of tube, the unit has no potential internal leak points.PEX is sturdy, tough and rigid. water temp rating range... 33F to 185F-200F (93°C) water! ...and if temps hit or fall below 32F (0°C) it's freeze damage resistant! it'll freeze but doesn't break. the connectors are made to last at least 25 years and pipe is rated 50+ years.

    • How to build a Offgrid Homemade Emergency Washing Machine that use no electricity.Also works as a Composter
      This project goes over the detail on how you can take an old 55 gallon plastic drum and turn that into a hand crank washing machine and a compost tumbler. The frameworks has uprights on the edges, holding up the barrel all the way down. The upright on the sides are 3 foot long 2 x 4. The base that it sits is 3 foot 2 X 4.Long brace that holds the two sides together is three foot eight inches long. You can take apart the whole framework by unscrewing the side rails and store the barrel for using them in an emergency situation. The barrel sits on a one inch hardwood dowel which is installed through one inch hole at the top of the upright. These barrels have a line in the middle of them so it is pretty easy to find the center by measuring across the line and then dividing it in half. The hand crank is made of PVC pipe with some screws to the end side of the barrel. The hand crank gives you something to grab onto if it gets very heavy so you can pull it back up and really move it around. It has a one foot by one foot door on the front .We use couple of cheap cabinet hinges to hold the door up when unloading the clothes. It also has a little S hook latch that locks it into place. A hole down in the middle of the barrel is for drainage. A small plug and a cap acts as a drain. The plug is put through the hole from inside and sealed with the help of PVC glue. Next step is to add agitators to our barrel . As you rotate the barrel, the clothes will roll over those agitators back and forth and get the clothes moving a lot better and help clean it. We add 3 PVC pipes inside the barrel that act as the agitators. You put clothes in through the top and add enough water just to cover the clothes, add any biodegradable liquid detergent and close the lid. Start moving the hand crank back and forth. This will agitate the clothes. The agitators slosh those clothes around, get them grinding against each other and that is going to clean all the dirt out of them. After about 15 minutes of agitation, we pull the drainage plug off the bottom and drain the water or recycle it by collecting them underneath a bucket and pour it around your plants and trees. As long as we are using biodegradable soap/detergent, the soap and the dirt that is in your clothes isn't going to hurt the plants. We put the plug back on, and fill the barrel with some clean water and agitate for another 15 minutes. This is the rinse cycle. Pull the plug, drain that water or use it on your plants. This setup can be also used a tumbling composter. Compost can be made of just about anything that was once alive .You can use leaves, grass clippings, garden waste, kitchen waste, chicken manure or any other waste material. Just dump all in there and turn the compost in there using our handle every couple of days for 2 weeks. We want to keep the compost aerated so that the microbes and bacteria that break down the compost can utilize the oxygen efficiently and help in decomposition. After 2 to 3 weeks, you probably have some pretty decent compost that you can use on your garden. Also through the drain hole, we can collect the residue compost tea which is high in nutrients. You can use that compost tea for plants that really need a good dose of nitrogen.
    • DIY Video : How to Turn old unused ceiling fans into a useful energy producer by building a Wind Turbine out of it
      A Beginner tutorial on how to make a wind turbine ceiling fan.So out of the box, we have the main part here, which has the motor in it.Keep up with all the blades if you can. You can use this for the furrow on the back the way it pushes around to keep the turbine from standing in a very aggressive wind it pushes it out of the way First part is just getting the motor outside of this casing. And you want to be careful because these wires are fragile, and you don't want to tear those loose by any means.So mainly, the tools that you'll need is just a screwdriver, maybe a flathead screwdriver and a hammer eventually. Take the top part of the ceiling fan off, this is the part that's next to the ceiling.Disconnect the wires don't cut them. There's a nut here with a washer that holds this plate.And we don't want this plate. So we need to take that off. However, we do want the washers here. Take this casing apart, and inside you'll see that copper coils that actually power the fan. The next step is finding the highest arm reading of these four wires that is coming out of this motor.Pull that higest ohm reading wires through the center pole to the other side. Insert a metal banding used for attaching the magnets around the stator. Put the magnets inside the fan housing to achieve a voltage reading.Add a cardboard spacer in there so that the magnets are aligned with the stator. The blades are made of 4 inch PVC.You can find templates online for the blades.Put the outline of the blades from the paper onto the PVC and then cut it out with a jigsaw. And then once you cut it out with a jigsaw, all you have to do is get a little Sander out, you can use a hand Sander to smooth the edges off. Connect the blades to the faceplate of the old ceiling fan. Next step is to take an inch galvanised pipe that forms the body of the turbine. A 40 inch piece will slide down into the conduit of the mounting system for your turbine.A 30 inch piece on the back,This is going to be angled up into the wind to keep the blades in the wind a little better. One Inch PVC is slid down the end of the 30 inch pipe and attach the tail piece on there which is made of fan blade The wires from the fan is passed through the pipe and just zip tie them down.Cut the PVC in half to a 45 degree elbow ,cut a line down through this PVC, we're gonna split it basically and drill some holes in it and attach the ceiling fan blade. Attach the fan to the galvanized pipe with the help of an extension that was previously saved during our dismantling of the ceiling fan.Use JB weld on the inside of that. And I put this bolt through this part and put a tightening screw on it, they're kind of digs into the metal. Connect the two leads from the fan to a bell wire, solder these two together, wrap it up with some electrical tape and kind of zip tie to the top so that it will stay in place.At the base end of the wire,connect it with a diode bridge rectifier which is further connected to our battery. Regarding connecting the rectifier,it doesnt matter how you solder them together,just as long as they are separate and not connecting and shorting out. But you want to put this at the base of the wire at the very end so that you can put this inside of your battery box and hook it up to your battery.
