This project goes over the setup of a simple battery bank for your offgrid applications.
We use three AGM batteries, and they’re about 245 amp hours each.Marine or deep cycle batteries also work. Dont get a car battery.Make sure that the batteries are about same age or they start bringing each other down.
The wires are connected through the positive ports and negative ports of each batteries.
The positive from the inverter is connected to the positive of the first battery .Negative from the inverter is connected to the negative of the 3rd battery.
The battery chargers are from Pros Series DSR.It ramps up the optimum charging voltage.
- How to build a Offgrid Homemade Emergency Washing Machine that use no electricity.Also works as a ComposterThis 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 build a really efficient Portable Multi Purpose Ammo Box Wood StoveThis project goes into the build of an efficient portable ammo can wood stove that can warm your space, act as a cooking stove, baking oven and an alternative for ground fires at camp sites. This ammo stove is compact and doesn't take up additional storage . All the basic components used in this stove are modular and can be stored inside the stove when not in use. These components are easily available in your local hardware store. The basic components needed to build this stove are as follows. The ammo box called the "fat 50 "is purchased from an army surplus store for $30 , the titanium stove pipe for $100 , the metal for the control dial and the door is salvaged from old barbecues. Rest of the basic tools needed are grinder, blow torch, hack saw ,rivet gun and a drill press. Not only you can use wood logs, paper, twigs but it also runs on wood pellets. The system has a gravity fed hopper that feeds the pellets intermittently for consistent heat over a longer period of time. For maximizing the burn, a divided combustion chamber is used. This forces the burn to go around a sealed baffle before it exits out the stove pipe providing less smoke and retaining more heat. A thick steel plate is used as a cook top which is rescued from an old barbeque . This plate absorbs the heat for cooking and is removable thereby protecting the stove top. Additional feature is a baking oven underneath the stove. The first step to build is simply removing the lid of the ammo can stove which just slides of the hinges. Remove the rubber gasket on the back side of the lid using a plier . This rubber gasket is replaced using 3/8th inch stove rope. This provides heat resistant seal from smoke. Remove the handle by drilling along the spot welds on the sides of the handle just enough to weaken them and pull it using a screwdriver . Two holes of three inches are drilled at the top surface of the stove . These are done to fit in the titanium stove pipe and for the gravity fed hopper system. We use a three inch propane fuel cylinder tube to make a pipe collar as a guide to trace out the holes. These pipe collars acts as hopper support for gravity fed pellet mechanism and for securing the stove pipe. The hole for the first pipe is about five and half inches away from the door hinge and the second one , one and half inches away. The holes are then cut using a jigsaw. The flanges in the stove pipe collars are made by securing them against a wooden fixture and bent them using a hammer. The edges are heated with a torch to anneal the metal for hardening. Before inserting the stove collars into the lid, the metal sheet inside the lid was removed. Using fiber glass cloth, a smoke seal is made around the collars. The collars are then inserted and the metal sheet is reinstated with help of some stainless steel rivets. A adjustable damper is installed inside one of the collars .These damper provide control to both burning speed and fire intensity. Also the damper in a closed state also acts a base for a steamer or a boiler. The damper is made using a thin steel cut out of a disc , the size of the inside pipe diameter. The shaft from a barbeque skewer is inserted along slots drilled in the disc holding them underneath the collar. Inside the combustion chamber ,we have two dividers installed. One divides the combustion chamber and the bottom one separates the oven from the stove . The top divider acts as an inner wall . The combustion has to travel around the corner and then go outside through the stove pipe at the end. This collects more heat and has less smoke build up inside. The side door openings are four inches high and three and three eighth inches wide. The door is made out of thick steel plate which was salvaged from an old barbeque. The door has three holes for the air intake and it is supported by a regular door hinge. A small circle metal piece at the front regulates the amount of flow that goes into the stove. A secondary burn system is introduced inside the stove so that the air coming into the upper part of the combustion chamber where all the smokes ascends gets reignited . This drastically improves the efficiency of the stove. Here we use couple of half inch black iron pipe that is connected with 2 90 degree elbow and an end cap. Holes are drilled on the pipe so that the fresh air is introduced into the chamber. A hole at the side of the stove is made the air intake. The pipe is inserted into the chamber and secured in place using a coupling and a spacer. A 3 X 4 inch duct adapter is used as a funnel for the gravity fed hopper system. To make this efficient , we add a small cage made of door basket inside the chamber so that all the pellets wont drop suddenly to the bottom. The cage is made from the metal rods from the basket. The rods are spaced 8mm apart and put straps across both sides and secured it using rivets. To prevent the overflow of pellets inside the cage, a two and half inch tailpipe is placed at a specific distance below the hopper. This helps the pellet build up in the cage but not overflow. Now there is a sustained release of pellets at all time for a consistent burn. Stainless steel tent stakes are placed at the bottom of the stove riveted to a metal plate. This prevents the bottom from burning out and also improves air flow. Also acts as ash collector. To use this stove as a light source, we make a small window out of half mm natural mica glass. We use a fiberglass cloth to form a seal around window. It is held by green painters tape. After positioning the glass, spacers are added around the edge . These metal strips allow for the mica to expand and contract. Another metal frame is used to hold all these in place. The portable stove pipe is made out of titanium rolls. The titanium prevents corrosion and also distributes the heat efficiently. To make a long cylinder without denting the foil, unroll the film across the ground, roll it small enough to get the clips on ,spacing them evenly along the length of the pipe. https://www.youtube.com/watch?v=t3XOLLg8wn0 https://www.youtube.com/watch?v=CskimuvL4ZI https://www.youtube.com/watch?v=TsHSfZ-nwws
- DIY Video : How to build a Survival Water Distillation System for under $5 and turn Salt Water Into Fresh WaterThis project goes into the build a simple survival water distillation system to turn your salt water into drinkable fresh water. This setup can be made with little more than two glass bottles, some metal trays and some sand. So the primary components of this setup are two glass bottles, the wider the bottles are in diameter ,the better and a pair of metal trays. The first part of this process will be to prepare an area such that the two bottles can rest mouth to mouth. The important part is that one of them needs to be suspended over a heat source. This could be done over an open campfire, you just need to find a way to suspend the bottle above the flame either using rocks or logs. Cut a small notch on one side of the pan so that the neck of the bottles can sit a little lower in the pan. This is by no means necessary, but it will make the setup a little more secure. With the trays secured in place, both of them are now filled with sand. The sand will allow the trays to more efficiently act as heat sinks, one tray to cool one of the bottles and the other tray will be used to very evenly heat the other bottle so that it doesn't shatter from being heated too much on one side. The bottle is pressed firmly into the sand so that it gets good thermal contact and will be heated evenly. The second bottle is adjusted such that its mouth will meet up with the first and it is also pressed into the sand to obtain good thermal contact. Another reason that I'm using sand for this is because it makes it very easy to adjust the bottles angles and it is best to make the bottles meet up as evenly as possible so that there is not much room for water vapor to escape. We want it all to make it into this second bottle where it can condense as freshwater. As an additional measure to keep the cold half of the bottle cold, we wet the sand on this bottle with water or cover them with a wet cloth to allow evaporative cooling to take place. With such a large quantity of sand in this tray it does take a little while for it to reach the boiling point and get this process started. But once the sand has reached that point, it stays hot for a long time. So it is a pretty quick process as the water boils dry in this first bottle to simply refill it and you can continue on with the distillation process as long as you want. Rotate the bottle so that the top portion becomes hot from the steam, it is rotated into the cold sand below. And in that way the entire bottle maintains a cold temperature which causes the distillation to go much faster. https://www.youtube.com/watch?v=R_-wFiFdwAE
