How to build an DIY 12 V Portable Water Pump Box with filtration system for Outdoor Survival / RV

    This project goes into the build of an offgrid portable water pump and filtration system that can turn any water from your creek,lake,river into safe and clean drinking water . This 12V portable system can be powered by solar or from your car directly and is ideal for camping , RV or outdoor survival enthusiasts. This system enables them to pump water from a fresh water source, filter and then store or use in case of emergency survival situation.

    The materials you need to build this portable filtration system are as follows. A tactix storage box to lodge the water pump,inlet and outlet hoses, an inline water filter or twin carbon 0.5micron filter, pex pipe, garden hose pipes, 12mill barb strainer,rocker switch ,12V Shurflo water pump with the flow rate of 11 litres per minute, 50 amp Anderson plug and 10m heavy duty wire ,basic tools such as wire cutters, long nose pliers, solder.

    The first step is completing the wiring for the water pump inside the tactix tool box. The rocker switch , the Anderson plug and a 7.5 Amp inline fuse are wired. The 12V rocker toggle switch is mounted at the center of the box lid.

    The power input plug or the Anderson plug is mounted to the left of the switch. This input plug connects to the car battery or a solar battery. The positive red wires from the switch is connected to the Anderson plug through an inline fuse .The negative black wire from the plug goes straight to the switch. The remaining wires from the switch is then connected to the water pump which will be installed later. The wires are covered with corrugated split tubing to ensure that it is protected and safe.

    The filter strainer is installed on the inlet side of the pump using an elbow, thread tapes. The strainer will filter out any unwanted debris before it goes to the pump.

    Couple of holes are drilled into to the side of the box where the inlet and the outlet hoses will connect the water pump. The male fitting are attached to the holes before the pump is installed.

    The pump is placed inside the box and mounted securely in such a way that the elbows are facing towards the two holes for the exterior hoses that was just made at the side of the box. Once the pump is mounted ,we connect the red and black wires coming from the switch to the positive and negative connections of the pump. The wires are once again covered with corrugated split tubing for safety.

    To connect the pump with the hose outlets , we measure the distance between the outlets and the pump and connect two pex pipes . Heat was applied to the pipe for bending and moulding them to connect the outlets.

    The 10 metre 50 Amp Anderson plug extension heavy duty cable wire is connected to the power source .Here the power draw is from a car battery. The other end is connected the input anderson plug on the top side of the box.

    The inlet hose with the strainer attached is placed sitting midway
    into the water source .The other end of the hose is connected to the intake pipe coming from the pump inside the box. The

    The other hose is connected to the outlet pipe coming from the water pump inside the box. At the end of the hose , we connect an inline water filter or a twin carbon filter . The carbon filter ensures that there is no sediments or debris inside the water and also helps to eliminate bacteria and other contaminants.

    • How to build a Homemade Copper Pipe Solar Water Heater and get super hot water fast and free
      This project goes over the build of a Homemade Copper Pipe Solar Thermal Water heater which can produce super hot water fast .This reaches temperature at or above 150F with air temperature from high 40's to low 50's. Here are the materials needed for this project are : Two 10 foot half inch copper pipes - Type L 16 half inch 90 degree elbows 18 tube straps 23 X 35 half inch plywood for the back 18 X 20 half inch plywood for the pipe support 2 X 2 lumber at 20 and 35" for the sides 4 and 3/8 inch square dowel rods for the glass support 1/2 inch threaded pipe adapter 3/4" to 1/2" garden hose PVC adapter 1/2 inch coupler. The first step is to cut down a bunch of two foot sections out of the 10 foot sections using a copper cutter. We cut 7 of them and 2 more for the top and bottom which are 30 inches each. Next we cut 8 sections of 1 1/8" for the connecter pieces between elbow joints. This allows the pipe to be spaced exactly two inches apart on the board evenly all the way up and down Connect the pipes using couple of elbows and a 2 inch connecter piece and solder them .Do it for the rest of the pipes. Slide the pipes into the plywood frame collector and fasten them onto it using 3/8 inch screws to be more secure. A small internal board is placed onto this frame which helps the pipe to lay flat inside .Also it holds the pipe at right height so that it exits through the right holes. It allows for the pipe to be easily removed from the collector frame. Cut the wooden dowel rods and put inside the collector to support the glass. Sand them a little bit so that the copper pipe will fit back through. A straight coupler is welded on to the end of outlet then you can add any pipe or connecter or wherever you want the water to go. The inner board is secured to the back board using some three quarter inch screws. The 4 corners of the 2 X 2 wood frame is secured using 2 and half inch wood screws and the corners of the back board is secured by one and one half inch screws. A 20 X 32 inch glass is placed on the frame with the help of some silicone caulk around the edge. The highest piece of copper in there is eighth of an inch away from the glass and its painted black.
    • How to build a Homemade Wooden Bandsaw Mill from Scratch.Step by step build Instructions
      This project goes over the build of a simple Homemade Bandsaw mill that can that turn hard maple into smaller lumber . The first step is to make the wheels of the mill. Here we use a three quarter MDF board to make this. The wheel size is 16 inch. We use a beam compass to cut circles and cut two wheels out of them. We make a seven and half pulley for the wheel using a three quarter inch plywood and drill a five eighth inch hole into the middle where the shaft goes. We take some hot melt glue and glue the stock collar onto the pulley and tighten it with a set screw so as to stop it from spinning. Before joining the wheel and pulley together, we make another small disc to go in between to act as a spacer .We glue the pulley to this spacer and from spacer to the wheel. Two wheel bearing blocks are bolted to the wheel on both sides using 4 three eighth inch threaded rods. Make sure that the threaded rods are tight inside the hole in the wheel, but the bearing blocks itself can move around. One way to keep these bearing blocks in place so that they dont move side to side is to apply some construction adhesive to the corners. Next step is building the frame for the saw from salvaged 2 X 4 boards. Make sure that the 2X 4's are straight. Take the bench hand plane and smoothen the edges so that the boards sit flat. It takes several shallow passes flipping the woods each time to get rid of all the twists and warps. Two frames pieces hold the wheel in ,the stationary drive wheel is placed eight and half inches from the end. Two five eighth inch holes are drilled on both the frames so that axles fits in there neatly. On the other side, one holes are drilled that gives the room to adjust the wheel. We also make an adjustment collar out of plywood that is bolted into the frame and the shaft . The collar can be moved to adjust the wheel. We also place couple of pieces across the frame and secure them tight so that the supporting boards are locked in position. On the other side we install the front wheel or top wheel. This wheel needs to move back and forth to put tension on the blade. It also must have a tracking mechanism. For that we make a two small piece that locks into the shaft on the front wheel and slides back and fourth. A guide piece is drilled onto to this piece . A one inch hole is drilled into our slider piece and a three eighth inch threaded rod is secured in there with a nut and washer. These rods help put tension on the blade and also adjusts tracking. Before putting the blades on the wheels, we put silicone caulking on the wheels to smoothen it out .These have advantage over bicycle inner tubes as it doesn't drape down over. The legs are attached to the frame using gusset blocks. To put the motor onto the frame , we take a melamine board and screw them aside the stationary wheel using a cross board. This piece of melamine not only supports the motor, it also helps to brace up the top to keep that from rocking. Secure them tight so that it resists moving while the cutting is going on. Next we make blade guides near the bottom to make a guard for the blades just in case it snaps and flies off. The blade guides are made of small piece of steel angle that is glued to a ceramic piece. The way blade guides work is that they don't actually touch the blade when it is running. It is only when the blade tries to move up or down that it will constrain it and keep it on track and prevent it from twisting. A thrust bearing made of regular size ball bearings is bolted onto an aluminum angle that is further attached to the blade guide. We make a dolly cart out of 2 X 4 boards and some castors to place the big maple logs and move it effortlessly through the blades . The castors are screwed in the ends using quarter inch holes. The castors are fixed in such a way that it moves only in one direction back and forth.
    • DIY Video : How to build a Homemade Atmospheric Water Generator . Produces/Extracts Distilled Water from the air
      This project goes over the build of an DIY Atmospheric Water Generator that distills water from air. This unit is made of aluminum and copper components so it is water safe and is drinkable. The water essentially is just pure distilled water just as clean as if it is distilled from a stovetop distiller. This setup works well in hot humid weather. Also acts a dehumidifier. The materials you need to build this project are quarter inch copper tubing, soup can, half inch PVC pipe, 12V DC aquarium pump, aluminum foil, clear vinyl tubing, aluminum tray for collecting the distilled water ,small styrofoam cooler box. Cold Water is pumped through two sets of coiled copper tubes. The coil becomes freezing cold and starts to condensate . Dew gets collected on the coil and is captured by a drip pan which is placed under the coil. The copper tubes are wrapped around a soup can to get the coiled shape. The clear PVC hose tube is clamped onto the coil and then connected to a small 12V DC aquarium water pump which is powered by a battery or solar panel. We take two half inch PVC pipes , connect them together with two elbows . Wrap the PVC pipes with some aluminum foil and place the pipes above an aluminum or glass tray. The water pump is then submerged in a chest box or bucket containing ice cold water. The pump is started and water coming out of the box cooler is sent through the copper coil where it will start the condensation process. Here the water is chilled to below its dew point. If the water is warm, it wont cool the copper coil enough for the condensation to occur. The colder the water and the more humid it is out , the faster the process of collecting distilled water. To improve the efficiency , you could squeeze the copper coils together . The more the coils, the more the water you can extract from air .
