This project goes over the build of simple and cheap homemade Air Cooler made out of an old juice carton and other simple items which can be bought from Home Depot. The whole setup is powered by solar energy .
The cost to build this AC Cooler is only $8.50 The drink bottle was a dollar at the store. The PVC pipe about $1.50, the DC Fan was $4.99 and the square dowels was 98 cents.
The materials you need for this project are :
1/2 gallon container
3/8 inch square wooden dowel
1 1/2 inch PVC pipe coupler threaded on one end
80mm case fan
Take the 80mm fan and put it down on the side of the container. Cut the three eighth inch square dowel and cut them the width of the container. Glue the fan on to the dowels on both the sides and the middle ones.
Take a pencil and mark around in a circle on the inside and using a small knife , cut out the circle from the carton.
Place the PVC coupler against the container and mark a small circle around it and cut along it. Widen the hole using a sandpaper such that the pipe fits in there properly.
Take out the fan and grab some pieces of ice cubes and put them into the carton through the hole and put the fan back on.
The fan is hooked to a solar panel. The fan has only 100 milliamps 12V power.
The opening of the juice carton can be used as drain pipe which be used to drain out the water as needed. Don’t waste the water. Just drink it, put a glass under there. Now you can get a nice cold drink of water after a couple hours.
- DIY Video : How to recycle your Waste motor oil,transmission oil or any waste fuel into 100% Re-Usable FuelSalvage waste motor oil, transmission fluid, old diesel that has water in it, whatever type of fuel that you might be able to have access to, wouldn't it be great to be able to take that fuel and run it in your vehicles and not throw it away? Or have to recycle it, you can recycle it yourself. Well, one of the ways is to filter. But filter material is expensive, and you got to constantly replace it. So I was introduced to this filter. Actually, it's a centrifuge by USfilterMaxx. This is just our initial test where we're going to take waste motor oil, dump it in the top of the centrifuge at spinning at about 3000 RPMs or more. And then we're going to drain and the result will be waste will be sludge in one bucket and clean motor oil and the other that can be mixed with diesel or run straight. In some diesel engines be careful on how you do this, you don't wanna mess up your injectors. But for old diesel engines that are very pretty forgiving, this is a great solution. So again, this stuff will go in my tractor or my old two cylinder diesel generator, but I'm just taking waste motor oil, and spinning out everything to make to make fuel, waste or motor oil has a ton of btu's in it. And mixing it with diesel makes for a very good sustainable solution. This is just some motor oil, nice and black from a friend of mine is changing oil in his truck. And we're gonna start with a two and a half gallon batch and run this through the centrifuge and see what she does with it. So you can see how black it is. Run the centrifuge on start introducing the waste oil. Okay, we're starting to get this filtered oil out.We're just doing a two and a half gallon batch run here. And then we're going to shut the centrifuge off. And the only way to really tell if we did anything was to see how much sludge is left in the centrifuge. That doesn't work until the centrifuge stops spinning because all the sludges is gonna be stuck to the outside wall. The sludge starts coming out.The centrifuge has stopped spinning, everything moves to the center and that's where the drain plug is This is the guts of the centrifuge. When this is spinning, it takes the oil coming in and pushes it out, and it comes over the dam, the clean stuff comes over here, it looks like it never had oil on it. And then that drops in here to come out the clean tube. When you stop spinning, the internal drains here. That's where the sludge is coming. The centrifuge run off a 220 power source. So you will need a generator or grid power to run it, or a pretty good battery bank in an inverter to run it We're gonna take our motor oil that we've just spun in a centrifuge, and we're going to put about a gallon and a half of it in this five gallon jug, and then I'm going to add a gallon and a half of diesel.We're gonna pour some of our motor oil mix and veggie. I mean motor oil and diesel 50-50 combination first. We've added a few cool features to our centrifuge we added a shell and tube heat exchanger made out of copper. So we can take hot water and heat the oil, the stored oil to a point where the viscosity is, is much lower, and it'll spin out a lot cleaner. We've added a little solar direct drive water pump, throwing off a little 20 watt panel, moving the hot water through the shell and tube. We've also added a P-trap to make sure any of the vapors from the hot oil do not escape into the clean oil bucket. They stay in the centrifuge and actually are evacuated out of the sludge side. We use thermo siphoning using a used water heater for the heat .This is free heat, there's no pumps, just thermo siphoning up to this tank and then using the little solar pump to take the hot water off the top of that tank and run it to our shell and tube. So pretty much off the grid water heating, heating lots of water using a thermal siphoning process. https://www.youtube.com/watch?v=3kOHhztok0Q https://www.youtube.com/watch?v=UKUCYuYM_Rc
- How to build a Portable 420 watt Solar Power Generator . Very Detailed Video Instructions,perfect for beginnersThis project goes over the build of a 240W Solar Generator made out of an ammo box.The box is large enough to hold a 240 watt deep cycle battery. There are some basic tools that you are going to need to build this generator.Number one tool, you're going to need a drill. If you don't have a drill, you can find one at Home Depot, you don't have to spend a lot of money.Next thing you're going to need is a screwdriver. Next, you're going to need wire cutter, a wire cutting and stripping tool. And it's also got a crimper on there. To drill the holes in the metal ammo box,you need a step up drill bit which can drill different sized holes, using all the same drill bit.You will need a pair of pliers which might be handy when you are cutting and manipulating wires and then basic wire cutters which also we have on the pliers. The next thing that you're going to need is the heart of the generator, which would be the battery. Now this is a rayovac deep cycle battery.I recommend that you use a V max deep cycle battery. The next thing you're going to need is a USB port. This is a two port device, it's got a one amp outlet and a 2.1 amp outlet.You're also going to need a 12 volt outlet. Faceplate,blade fuse holder,terminal connectors,switch,self tapping screws,14 gauge 17 amp black and red wires. We use a 3 prong switch,one of them gold in color which is the negative terminal and the other two positive.Purpose of the switch is to control your USB outlet. And it's what turns the USB outlet on and off. The positive terminal on the USB outlet is first going to run to the positive terminal on the switch.Now the purpose of this switch is to break the electrical current when you turn it off. So positive terminal goes to positive terminal, then the second positive terminal on that switch goes to the positive terminal on the battery. So you've got a flow of electricity going from positive through this switch to the positive terminal on the USB port. The negative terminal on the switch goes to the negative terminal on the battery. The only purpose of that terminal is to control the LED light on the switch, it needs the both positive and negative electrical currents in order to turn that light on. Similarly for the 12V port,positive connector going to positive terminal going to the positive terminal on the battery. Lets start the build. Start with drilling holes for the ports using the faceplate.Get your marker and simply trace the inside from both the top and the bottom.So that's where your holes are gonna go. Now we want to find the exact centers that when we're drilling. Insert the 12V and the USB outlet into the holes which we have just drilled. Now these ports have a little ring that screws on the back. This is what holds it in place. Next thing we're going to install is the power switch and SAE Solar Power Socket and the voltmeter. To begin wiring our tabs batteries, you're going to need a few things. Number one, you're going to need a battery. Number two, you're going to need your quick disconnects. You're going to need your squeeze connector connector,your wire cutters and stripping tool and you're going to need black and red wires. Place the vmax battery into the ammo box.So we've got everything in place, we have our ports in place, we have our battery in place, we've got our switch in place, and our volt meter. We're gonna start by wiring the USB port. The positive connection of the USB port is connected to the positive of the switch which is further connected to the positive of the battery.The negative connection of the USB is connected to the negative of the battery. This switch will break the flow of electricity on the positive side and that's what's going to turn our USB port on and off. Using squeeze connectors,USB port negative terminal is now connected to the same negative terminal as the 12 volt port.Connect the positive terminal from the switch to the positive wire which is coming from the 12 volt port and continue that positive flow from the switch to the positive terminal on the battery . So we now have our USB port and our 12 volt outlet connected to the battery through the power switch. We've got the negative terminal of the USB port, going to the negative terminal on the battery, we have the positive terminal of the USB port.Then we've got a positive going from the switch to the positive on the battery all through quick disconnects. The negative terminal on the battery going to the negative terminal on the switch simply allows the switch LED light to turn on without this negative current flow of electricity. This the LED light has no power.So we want to give that light power by connecting to the negati.ve terminal on the battery. The negative of the Voltmter is directly connected to the battery and using insulated clamps,we connect positive wire that's already running to the switch for the USB port.Now we want to connect to the positive wire leading to the positive terminal on the switch so that the volt meter will turn on and off with the switch button. Next, we're going to cover the SAE port. We want to be able to have the battery charged when we plug this into a charger.Using the squeeze connector we connect the positive to the positive terminal of the battery.And then same thing for the negative, you would take your squeeze connector and connect to the negative. Lastly,A 15amp fuse is used to protect the generator from overloading. If you connect at current that is too high for their internal wiring to handle, the fuse will break and it will stop all electrical current from flowing.So if anything goes wrong in any of this wiring, it has to get past the fuse before it reaches the battery. So if there's anything that's that's overheating, or overloading this fuse is gonna blow and it's gonna protect your battery from being damaged . Next step is connecting a solar panel to your generator .We connect the panel to the charge controller and then from the charge controller to your ammo generator. A charge controller prevents the battery from overcharging. You don't want to get over 15 volts. Here we use Renogy 30 watt solar panel, this panel comes by default, with an SAE connector on the back. This is the same kind of connector that plugs into your generator. Connect the wires coming out of the Solar Panel into the charge controller.Next is connecting the SAE cord from the generator to the charge controller. So you just put the panel on the charge controller, the charge controller into the generator, and you're done. If you want the whole system to be portable, say you want to be able to take your solar panel and your generator camping, you want to keep things as simple as possible, you could actually mount the charge controller directly onto the back of your panel. https://www.youtube.com/watch?v=MVVRPUHUMUo https://www.youtube.com/watch?v=DW6C-ZjmRzo
- How to build a Simple Alternative Power Dual Refrigeration System that uses no electricityThis project goes over the conversion of an old three way refrigerator unit from an RV into an alternative power offgrid Dual refrigeration system that uses no electric power. This can be really useful in case of a power outage or SHTF situation when you need to keep your food or vegetables fresh. The first step is to strip the fittings on the back side of the fridge , remove all the ammonia system ,clean the inside of it . Here we are incorporating more than one way to use this water for cooling refrigeration system to make it efficient .We will be using cooling effect by brining down the water temperature to cool the box , another way to cool the box is by installing an evaporative system. We take the two pipes coming from the water source around the edges of the box and put some cotton sheets around the sides and let the water cascade down the sheet creating an evaporative effect. We have an inverter and a battery attached to the fridge that is hooked up to a 25W solar panel .The wire from the inverter is connected to 8W Electric Fish tank pump .The water coming from the pump goes underneath and up inside to the lid of the fridge to the condenser coils and then comes back around back into the water source like well or water tank. The full system is recirculated back into the original storage tank where the water is coming from. We keep the fridge in a chest freezer style instead of an upright style. Inside the fridge, we have incorporated 2 poly tubing coils attached to an old heat sink that was already in the fridge. The 100ft coils are attached to the top of the fridge. The cold from that coils will drop down to the rest of the fridge. Next step is to incorporate the evaporative cooling part of the refrigeration system. We start by installing aluminum U channels across all the edges of the fridge. The U channel will hold cotton material inside of them. The water coming out of the outputs from our coils rushes into the channel which is going to wick out into the cloth and run down the cloth with gravity, giving us our evaporative cooling effect . On the corners, we have the U channels interconnected to each other through a bent garden hose in such a way that any extra water flow in the channel can transfer to the the channel that is next. The cotton sheets are stretched around the box and tuck it down into the channels all the way around under the wires such that the wires will hold the channels up and hold the sheet up inside the channel. To even the flow of the water ,we install a tee. Now the water coming from both sides of the channel can leak into the sheet. Also make sure you have an air gap between the sheet and the refrigerator box. https://www.youtube.com/watch?v=mHspLgLWJug
