DIY Video:How to build an awesome Roof Top Portable ABS Pipe Hot Water Heater/Shower . Great for Camping/ Outdoors

    This project goes into the build of a DIY solar powered pressurized roof top water heater and shower that is portable for outdoor survival and camping trips. This project is easy to make and requires only minimal tools and plumbing parts.

    The dimension of the pipe used for this build is six feet tall and four inch wide. This has a capacity of 15 liters. The materials you need to build this project are six feet long four inch ABS pipe, air compressor, two four inch PVC end caps, abs cement, rubber schrader valve, shutdown valve and retainer nut, radiator valve drain plug , forstner bit,two inch threaded end cap, high heat flat black paint, steel wool scrubber, methyl hydrate.

    The shutoff valve is installed as low as possible in the pipe to avoid the necessity of having to tilt the system. Mark the position for the valve keeping the retainer nut in place , we insert a forstner bit into the nut creating a center mark for the drill .Once the hole is drilled ,we thread the shut off valve into place and attach the retaining nut.

    For installing air compressor for pressurizing the tank ,we use an long schrader valve that is used for aluminum rim tyres. This valve uses threaded nuts to secure it in place .

    Next step is to install the water intake opening. For this we use a two inch PVC threaded adapter socket . We take the diameter of the fitting and then drill out the opening and glue the fitting in place using ABS solvent cement.

    A radiator valve drain plug is installed on the threaded end cap of the water intake PVC fitting .This valve helps to release extra pressure from the tank without opening the main drain shut off.

    In order to improve thermal absorption of solar energy, the surface of the ABS pipe is painted with flat black paint. The surface is polished with steel wool soaked in methyl hydrate and applied one coat of spray primer followed by two coats of high heat restoleum black paint.

    To mount the shower to roof of the car or truck , we use a canoe foam block . We extend the slots in the foam block to make them fit inside the cross rails . An arc is cut on the foam block equal to the outside diameter of the pipe and positioned it such that it left half an inch of foam between the mounting slot and the bottom of the arc. To attach the shower to the support pads, here we use one inch nylon tie down straps. With both these pads in place, the water heater is securely attached to the roof.

    An inexpensive 25 foot long coiled three eighths inch hose from the local garden center is used as the shower hose. This would be perfect as it is easily stored and can be taken apart after use. The air compressor is connected to the pipe with the help of a multifunction spray nozzle .

    Thee bursting point of six inch ABS pipe is well over 100 psi .So a 30 psi would provide safe and ample pressurized shower without any long term expansion fatigue to the pipe or glue connections .

    • How to set up a Complete Off the grid living System using Solar and Wind Turbines . Make your own Power and never pay for electricity again.
      If you're going to run your home ,cabin or garage off grid, you are going to need some way of having power. Enter Solar and Wind. This project goes over the build of a complete off grid power generation system that can harness the clean and green renewable energy of the sun and the wind. Here is the basic rundown of the system .We go from sun to solar panels, there is no limit on how many solar panels we can put. It goes into a charge controller, it helps the solar panels create really efficient electricity to be pumped into your battery bank. Charge controller also makes sure that the batteries are being charged correctly and stay optimum. So solar panels to charge controller, and then that goes directly to your battery bank. The other source of renewable power is wind. The wind turbine is connected to a stop switch that goes into your battery bank. In some cases in between you can put up a wind turbine charge controller. Next step is converting the DC power to AC power with an inverter. The inverter basically converts the power to make it usable for your home. The inverter also has to be sized appropriately. From inverter to breaker panel which spreads the the power out throughout your house through your light switches, wall sockets. From breaker panel straight to your house or cabin. The first step is sizing your system. The battery voltage is going to determine what type of equipment you are going to be buying, and how you are going to be wiring your battery bank. So if you go with a 12 volt system, then you are going to want to make sure that your solar panels are wired up correctly for 12 volt. Even when you go with a wind turbine, you are going to want to make sure you buy the correct wind turbine for your battery voltage .So everything has to be sized appropriately so that you can collect as much energies as efficiently and then you can draw that power out. The golf cart batteries in my system are of 6 Volts. I have 6 of them wired in parallel, and in series to give me a 12 volt battery bank. The control panel box consists of my charge controller, voltmeter and 2 ammeters for both reading both solar and wind power amps. Four 12V Solar panels , each 100 watts are wired together . All the positives are connected to each other and all the negatives are connected to each other. The wiring goes straight into the control panel. The wind turbine used here is also 12V.The 3 Phase connections from the turbine goes into the bridge rectifier. The negative connection from the rectifier goes straight to the batteries, the positive goes to a junction box that connects the turbine and the inline fuse and 50amp breaker. The negative of the inverter goes into the negative of the batteries ,positive to positive. The romex wire from the inverter goes into the breaker panel in the house. The Permanent Motor Alternator turbine stands on a 6 foot pole .We have these two steel pipes that go down into the ground, three feet. There's another piece of steel that runs across here that's welded together, and it's in the bottom, and then we poured concrete over it to anchor it. Three tie down points are connected to the turbine to keep the pole steady from rocking around especially in high winds. So that way, when the blades turn, the bearings don't get worn out prematurely from wobbling. The Permanent Motor Alternator (PMA) used in this turbine consists of 2 shell casing, two bearings, a rotor inside and a stainless steel shaft. The tail of the turbine is made from a sheet metal cut to look like a fin.It is attached to a steel pole.This is further connected to the PMA alternator. The 11 blades of the turbine is attached to a hub and a pulley through a steel shaft. The belt is connected to a secondary pulley which is connected to the Permanent magnet alternator. The wire from the PMA is connected through MC4 connectors to the control panel. Wind turbine and solar power system overview : Setup of the wind turbines :
    • How to build a Large 2000W Portable Solar Power Generator at Home from scratch.
      The idea of a completely silent power generator that can still run large power loads, and never need gasoline is a really cool concept. This project goes over the build of a large 2000W Portable Solar Generator that can power appliances ranging from a table saw to charging your phone effortlessly. We need a large box to hold our basic components. Here we use a pelican 1620 protector case that is durable, dustproof and waterproof .This is going to be the case that we package everything into. It's got wheels on the bottom so you can roll it around ,also has heavy handles on either sides. The battery is a AGM glass mat ,coil would style, 12V optima deep cycle battery. A deep cycle battery just allows you to get a little bit deeper into the discharge before you are starting to shorten the life of that battery. This battery also has the ability to be mounted in any orientation . So it is safe whether the battery is on its side on its back or even upside down as long as we have it mounted securely so that nothing shorts against our terminals. The next major components for our build is the 2000W inverter from Krieger. This one has some large terminals on the back for our wiring. Also has a active fan here for ventilation. Also comes with a remote control switch. The 100W Solar Panel is from Renogy. It has the bus on the back for connecting in to your solar charger .It also comes with a 30A Solar Charge controller. This can run up to four of the 100 watt panels in a 12 volt system. The back of the solar panel comes pre wired with MC4 connectors, as well as a couple of MC4 pigtails. We use high quality 16 gauge speaker wire to extend the connection. These wires are highly flexible for portable use. To connect it to the MC4 pigtails we need to go ahead and strip the insulation off and use butt splice connectors to crimp them to the MC4 pigtails. In case you cant to charge the system with standard AC power ,we use a 1.5A Battery maintainer / Float or Trickle charger. This will be good for just keeping it topped off when it is in storage. Or if you just want to charge up your batteries and you really don't have a place to be setting the panels out. Next step is mounting components on the outside of the case . Before mounting any component, factor in how the internal components are going to placed inside the case. On one side of the case ,we are going to mount a small LED work lamp with toggle switch, a 12V gauge pod with 5V USB output, digital voltmeter,12V cigarette socket ,an AC input plug for using with the trickle charger, a 6pin solar panel trailer connector. These components are secured in place using a RTV silicone sealant. One the other side of the case , we are going to mount the inverter remote control switch, 350A high current plug which is used for jumper cables or to add high current loads, a GFCI AC outlet with a weatherproof cover. The GFCI outlet is connected to the inverter inside the case. We want to put the battery as close to the wheels as possible, because that will help keep the heaviest part down low when moving the case around either on the wheels or by carrying it. We place it snug into a corner of the case using battery mount and couple of pieces of 2X4. The inverter is placed inside the case in such a way that there is enough space for air ventilation and for tucking some of the wires underneath. The inverters are secured in place using mounting tabs and 10x24 machine screws. The PWM solar charge controller is also mounted in the same way near the solar panel connector input. The trickle charger / battery maintainer is placed as low into the back of the case .This is not something that will get very warm so we don't need to worry about heat dissipation or anything like that . We plug the power cord from the trickle charger into the AC input cord. Next step is the wiring. We start by connecting the power cables from the inverter to the battery. The positive and negative from the inverter is connected to the positive and negative of the battery respectively. To distribute power in our generator ,we use a six circuit fuse panel for the positives and a busbar for the grounds. We use two inexpensive battery cables to run the power to our distribution blocks as well as running the power to our high current quick connector. The positive red connection from the quick connector goes to the fuse panel and the black negative connector to the ground busbar. Both connections are further extended to connect to the positives and negatives of the battery respectively. The LED lights are connected to the 3 way connector switches. The switches are further connected to the power distribution fuse block. Similarly a single switch is connected to the USB outlet, voltmeter and the cigarette lighter ports in parallel. The positive from the switch is connected through a daisy chain mechanism to the three positives of the ports ,the negatives are similarly connected to our distribution block. At this point, we now have a power wire and a ground wire for every single one of our accessories connections . We bundle these wires and keep it neat and tidy using zip ties. Separate the positive wires from the negative wires, we are going to be rounding the negative wires to our ground busbar. After we have all of the ground wires connected, we can move on to the power wires on our distribution block. Each one of the blade connectors represents one fuse circuit. We connect the positive red wires from charge controller, battery trickle charger, usb ports,voltmeter,12V outlet to the fuse circuit. We are using a 30A fuse for the charge controller,12V socket, 20A for the LED work lights, 5A for the trickle charger.
    • How to recycle scrap metal in the backyard by building a simple Mini Metal Foundry from start to finish
      In this project, we're using equal parts of sand and plaster to make a simple backyard foundry that's powerful enough to melt scrap metal in seconds. With this homemade furnace, we have the power to liquefy aluminum in the backyard and cast just about any object we can think of. You will need some big bag of play sand and some plaster of paris both of which you can find at your local hardware store for under $20. We are also going to need a 10 quart steel bucket and a tablecloth to cover anything. For this makeshift refractory lining we need One and 1/3 buckets full of plaster Paris or 21 cups, One and 3/4 buckets full of sand or 21 cups and 1 and 1/4 buckets filled with water or 15 cups. Mix everything together. It's really important to get all the dry powder wet and work out any lumps as quickly as possible. And after mixing for a couple of minutes, it should be fairly runny and roughly all the same color. Transfer the mix to the steel bucket upto 3 inches from top. We use the plastic measuring bucket to form the center of the foundry. Let the mixture dry for 3 minutes. Next step ,we turn an old steel fire extinguisher into a custom crucible. Depressurize the tank and unscrewed the valve from the top to make it safe and easy to cut in half with a hacksaw. At this point the plaster should be pretty well set. So let's dump the water from the bucket then use a pair of channel locks to pull the bucket out. Next step is make an air supply port .Using 3/8 inch hole saw and a metal cutting blade, we cut a hole to accommodate the one inch steel blower tube. The blower tube is made of one inch steep pipe ,one inch PVC coupling and one inch PVC pipe.Threads on one half of the coupling screw onto the steel pipe and the slip adapter on the other end simply pushes onto the PVC side easily. Next step is to build a lid to retain the heat.You need a couple of 4 inch U bolts.Make them stand upright into a 5 quart bucket filled with the insulating mix. To relieve pressure buildup, make a vent hole using a 3 inch hole cutting saw. This design works great for venting pressure and gives us the option to melt metal as well without even having to take the lid off the furnace. By the way, if you run out of soda cans to melt, you could try using it as a blacksmithing forge or even a barbecue for summertime grilling. We evenly place 5 charcoal briquettes at the bottom of the crucible made out of steel fire extinguisher, helps smelt the can faster once we fire it up. A hair dryer is taped to a PVC pipe and inserted a couple of one inch couplings to connect the steel tub eat one end and give the blower to a quick release feature. This way it's super easy to take apart and fits into a five gallon bucket for easy storage. The charcoal is filled it to the top and we breathe life into the steel furnace with a propane torch.The hairdryer is set to the low setting and blow a steady stream of oxygen on the charcoal to really heat things up. The lid we made keeps the heat inside so it conserves energy while it's bringing up the temperature. The coolest part is that the crucible lines up perfectly with the hole in the center. The container is three inches wide, which is the perfect size for melting standard size soda cans like these and at temperatures over 1000 degrees Fahrenheit . In order to isolate aluminium, first we remove the crucible making sure we have got a very secure grip with our tongs and slowly pour the liquid into a steel mold. The Soda cans are molded in the form of ingots.The purpose of an ingot is to keep some pure metal handy for when you want to make something cool.
