  • How to build a Homemade Water Powered HHO Dry Cell Generator
    This project goes over the build of a Homemade 19 Plate HHO Dry Cell Generator . The HHO generator works by the principle of electrolysis. Water is made from two types of atoms hydrogen and oxygen. Electrolysis is a method for splitting water into hydrogen and oxygen. Pure water isn't electrically conductive, so we add either sodium hydroxide or potassium hydroxide to it to make it conductive. To make the electrolyzer , we need electrode plates, neutral plates, gaskets, front and back plates with some metal reinforcements . The electrode plates and the neutral plates are made of 304 stainless steel sheets, the gaskets made from one eighth inch neoprene rubber sheet. The neutral plates are stacked in between the positive and the negative plates .The empty spaces are filled with neoprene gaskets. Water comes into the electrolyzer through the input tube and goes out as hydrogen and oxygen through the output tube. When electricity is applied to the electrodes, the chemical reaction occurs, which causes the hydrogen from the water to go to one plate and the oxygen to the other plate where there they form bubbles of gas .Now the electricity wants to jump from the negative plate to the positive plate but since we have neutral plates between them, they divide the original voltage. This help in efficient HHO gas generation. The plates are made of 12 X 12 .24ga 304 stainless steel sheets that is cut into four 6 inch pieces using tin snips . The plates are stacked together and holes are cut top and bottom for where the gas and the water comes in and leaves. To hold the plates together use seven inch cutting boards with metal support frames at both ends. To differentiate between neutral plates and the electrode plates, we cut both corners of the neutral plates and only one corner of the electrode plates. So this way we can run a bolt from the positive to the other positive and negative to other negative end. To assemble the cell, we place onto the base cutting board, the positive electrode plate and stack the neutral plates and the gaskets on them one by one and enclose them the negative electrode plate and the base board .Secure them with bolts on four corners. The electrode plates are then connected to each other with a thin gauge wire. The next component for the build is some sort of a water reservoir. The reservoir is nothing more than a bottle that's going to hold your electrolyte, which is distilled water and either sodium hydroxide. The water reservoir is connected to the cell using two three eighth inch tubes, one going into the cell and other coming out . The other component that you're going to need to build this HHO generator is some kind of a power supply that can generate 12V 30amps . This can be a car battery hooked up to a trickle charger, an old computer UPS supply or a 12V battery used for solar panels. The electrode cells are then secured on a wooden frame along with the power supply and the water bottle reservoir for easy portability. Next you need a bubbler .This takes the HHO gas coming into it and diffuses them and gets broken into smaller bubbles. As those bubbles travel up the column of water inside the bubbler, it helps to filter out the sodium hydroxide or potassium hydroxide vapors .If your bubbler is set up correctly, then after being diffused and traveling up that column of water, it tends to get rid of most if not all those vapors. To add a safety feature ,we drill the top of the bottle , remove the lid and cover it up with a plastic foil pressure membrane . If the pressure inside the bubbler increases in case of a flashback ,instead of the jar exploding, the pressure is able to escape through the membrane . https://www.youtube.com/watch?v=ILzMhqEFMeI

  • DIY Video:How to build an awesome Roof Top Portable ABS Pipe Hot Water Heater/Shower . Great for Camping/ Outdoors
    This video shows the build of a DIY solar powered, pressurized, roof top water heater and shower.This is done using an ABS 4 inch pipe, 6 feet long, which would give me a capacity of 15 Litres or 4 US gallons.This is an easy and inexpensive project that required minimal tools and just some basic plumbing parts.I started by installing the shutoff valve. I wanted the drain to be as low as possible in the pipe to avoid necessity of having to tilt the system. To ensure the valve retaining nut did not interfere with the pipe once it is glued into the, I positioned the nut away from the wall of the cap using a bolt, which is the same thickness as the wall of the pipe.I drilled out a 2” threaded cap and tapped in a radiator valve drain plug that I picked up at the local automotive parts store. This valve will allow me to release pressure from the tank should that be necessary without opening the drain shutoff. Also when open, this will allow a gravity fed system through the drain valve should for some reason I not have access to the air compressor.As a final step to improve thermal absorption of solar energy, I painted the surface with flat black paint. First I lightly buffed all the ABS surfaces with steel wool soaked Methol Hydrate. Then applied one coat of spray primer followed by two coats of flat black paint.

  • 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. https://www.youtube.com/watch?v=hHD10DjxM1g https://www.youtube.com/watch?v=lSoWxG30rb0

  • How to build a Backyard Waste Oil Burner Powered Water Heater to produce Free Hot Water for your Home
    This projects goes over the build of waste oil powered free hot water heater for your home .This converts an old used domestic water heater to run on waste oil, engine oil or cooking oil. With as little as one liter of waste oil, this heater gives twice the heat output than a domestic electric powered water heater .As waste oil is free, this is more economical than running on gas or electric. The setup of this waste oil heater is very simple and easy. We have a waste oil burner that is placed under the domestic water heater. The burner is connected to a blower from a car. This blower is powered by a 12V battery charger . The burner is also connected to a drip feed waste oil pipe through a small pipe. The oil feed from a suspended tank, which gives it a gravity feed dribbles into the inlet pipe on the burner and it is simply blown into the burner by the force of the air from the blower. To control the oil flow ,we have a valve on the oil tank. The cold water comes into through the inlet hose at the bottom of the tank . From there burner just fires the heat up through the center of the heater as it would normally if it was gas fired. The hot water comes out from a outlet hose at the top of the tank. The waste oil burner is made out an old fire extinguisher bottle. The beauty of using extinguisher bottles is you don't have to worry about any flammable gases in them, and the metal seems to be quite durable. Make sure that the air and the fuel enter the bottle at a slight angle in order to create some swirling. This makes sure that the air and the fuel mix and will burn completely. And also that the bottle is kept hot so that the liquid oil will vaporize and the gas will burn. The inlet pipe for the waste oil and the blower is positioned at 25 to 35% of the way up to the bottle. The inlet pipe has a small bend in it so as to promote swirling within the bottle. This is important in keeping the bottle hot and self sustaining. The burner has a clean burn with almost no smoke. The output of the oil burner can be controlled by the amount of waste oil being dripped into the burner and by the amount of air blown into it. This oil gas burner is more powerful than a gas burner and the heat produced can overpower the heat sink threshold of the water heater . A vent line is installed on the system so that any build up pressure can be released. Apart from heating hot water , this set up can be used for space heating , pool heating or garage heating. https://www.youtube.com/watch?v=L4xq_GSjWLI

This project goes over the build of a cheap Geothermal Solar air conditioner that can cool your home with the Earths natural cool temperature.

A few feet underground, the temperature remains between 55 and 60 degrees Fahrenheit. This is true regardless of the weather above ground.The geothermal unit siphons heat from inside and vents it into the water or refrigerant in the loop. The cool temperature underground then lowers the temperature of the liquid back to 55 degrees.

In my case when I draw the water well, the static water level is 2 feet above the ground and and what that means that there is a free flowing well that runs down the hill.

This is connected to a 55 gallon drum buried in the ground to keep it cool. A circulator pump is used to pump the water to the radiator.

The water well is about 85 feet.We drop a 10 foot pipe in there and get a cheap pump from a car and probably some check valves valves and maybe start a natural siphon and run out of solar.

You will need an old car radiator for this project. The Radiator used here is from an old Volvo Car. This is used to circulate air using a solar panel.

The water coming in is connected to the radiator and the water coming out the is attached to a PVC drain pipe . The radiator is hooked to a motor connected to a solar panel.

A Temperature sensor is attached to the radiator fan to detect the indoor temperature. The pump is out of the same Volvo car from which I got the radiator. A Coolant temperature sensor can be added to measure the temperature difference from the inlet versus the outlet and just see how much heat get pulled into the water .

The system works on Solar.You will need a Charge controller,DC to DC Convertor and 12 or 24V batteries.

  • 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

  • How to build a Simple Alternative Power Dual Refrigeration System that uses no electricity
    This 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
