DIY Video:How to build a Simple Homemade Pocket Straw Style Water Filter. Small, lightweight and powerful.

    This project goes over the build of an emergency Straw Style Survival Water Filter. This water filter is small, lightweight and ideal for an SHTF scenario or hiking/camping. Very effective for purifying rain or tap water or removing disease causing water contaminants. With regular maintenance the filter should last for years.

    The materials needed to make this water filter are turkey baster , cotton balls, coffee filters,activated carbon. All these materials can be purchased from your local store or aquarium supply stores. The activated carbon is rated to last for five months if used regularly.

    Start by taking a cotton ball and push it down the turkey baster.

    Rinse the activated carbon by running it through tap water before putting them over the cotton balls.

    Pour the rinsed activated carbon all the way to the top of the pipe and put two more cotton balls at the top .

    Now take some coffee filter paper and slide it over the top of the cotton balls and tie it down using a twist tie or rubber band so that the whole thing wont slip out when you are using it. If you don’t have the cotton balls available, you can always just ball up some pieces of coffee filter paper and put them on either end of the activated carbon in between.

    An alternative way of using this is to cut the top of the poultry baster and and put it on the top of the straw . Take the dirty water and manually filter it through the straw.

    Once the material inside the filter gets saturated water moves pretty thoroughly through the straw. The cotton balls in the paper will get dirty pretty quick up here capturing most of the dirt but you can just pull those out periodically and add new ones.

      This video series shows the build of a smokeless wood burning boiler from start to finish.It is built from a old hot water tank and a small air compressor tank and costs next to nothing to build.The first video of the seriesĀ  will show the construction of the boiler itself. The next video will detail how to hook it up to a pump and exchanger to bring the heat inside. The final video will show modifications I make to the stove to make it even more efficient.

    • How to build a DIY Passive Solar Thermal Water Heater. Simple and Efficient!!
      This project goes into the build of a passive solar thermal water heater using pex pipes and 4 X 8 plywood piece. The pex pipes are sturdy and tough , doesn't easily leak. This passive solar heater can reach upto 120 - 150 F on a typical sunny day. Instead of pex pipes, you can use cheap irrigation pipe for this project. The pex pipes are more stronger and durable . The heater can be used for heating your domestic water, space or room heating or just heating a swimming pool. The box that contains the pipes are made of 4 X 4 plywood . Four pieces of 2 X 4 pressure treated lumber are joined along the sides using screws to make the frame. We staple in some bubble insulation along the dimensions of the box . Since the insulation material is silver, it will reflect heat. To avoid this ,we coat it with a flat black paint to attract the solar heat. Two holes are drilled on the sides of the frame for the inlet end of the pipe where the cold water comes in and outlet end where the hot water comes out. The inside and the outside of the heater is painted flat back using rust-oleum high heat paint to absorb maximum heat from the sun. The first layer of half inch pex tubes or irrigation pipes are secured inside the solar heater box using half inch pex talon clamps. The clamps are installed on four sides of the box securing each loop of the pipe. The second or upper layer of pipes are secured in using zip ties. The total length of the pipe is 200ft. The pipe comes in through the inlet hole and goes to the outside on the first layer , all the way around and work itself inside .It then goes through the top layer and all the way to the outside and then exit through the outlet hole. The bottom layer pipes aren't going to be exposed to the sun as much but they still will be warmed up because the whole box is covered with lexan polycarbonate sheet. The top layer with the pipe that goes outside through the outlet hole will have the highest thermal BTU. A very inexpensive reed thermometer with a 4 inch stem is installed on the side of the heater using a half inch to three eighths bushing reducer . A 4 X 8 Makrolon Polycarbonate Sheet is placed on top of the heater box and secured down in place using a No 8 One and one fourth sheet metal screws ,finishing washers and rubber grommets. Silicon adhesives are used to seal the gap formed between the sheet and the box frame. The Solar thermal heater is placed at an angle of 20 degrees. This is done with the help of leg supports with dimensions 16 and 8 inches 2 X 4 pieces at both the sides. A 50 watt Renogy Solar Panel is also installed adjacent to the heater. This Solar Panel is for powering the bilge water pump. A 500GPH 12V bilge pump is used to pump the cold water through the pipes into the heater . In order to control the flow of water through the pump , it is connected to an speed control electric circuit box which has a relay, a buck boost converter,a motor pump speed controller, potentiometer and a switch. The pump is powered by a 50W Solar Panel .The negative connection from the panel is connected to the relay, the positive goes to the switch. The relay determines the voltage for the buck boost converter .It activates on a certain voltage we set and then powers the buck boost converter. The buck boost converter will keep a constant voltage no matter what the voltage the solar panel is putting out. It is then connected to a 15 amp motor pump speed controller and a potentiometer which is used to control the voltage of the bilge pump motor. The 12V 500GPH bilge pump is connected to the motor pump speed controller. In order to test the unit, we place the heater near a pool to heat it. The bilge pump is submerged into the pool which is then connected to the heater with help of a PVC hose. The output pvc hose is returned with heated water back to the pool. The water reaches upto 140 F based on our test.
    • How to build an Emergency Waste Oil or Used Vegetable Oil Candle from Old Nail Polish Bottle
      This project goes into the build of a simple and inexpensive waste oil/ used vegetable oil candle from an old nail polish bottle. You can burn motor oil ,vegetable oil, olive oil or you can also use lamp oil in these types of candles. The first thing your need for this oil candle is a reservoir to hold the oil in. Here we use a finger nail polish bottle. Next , a length of 100% cotton yarn is needed that is slightly longer than the length of the bottle. Another requirement is a one inch square piece of aluminum foil. The first thing you need to do to start this process is to take the bottle , clean it completely and fill it with your source of fuel like veg oil, waste motor oil, corn oil, olive oil . When you are pouring the oil, you don't want to go all the way up to the top of the bottle. Leave small amount of space at the top of the bottle. Take the aluminum foil and fold it length wise in half .Puncture a small hole in the middle of the foil . Through this hole, the cotton wick is pushed through. Lower the wick into the bottle and fold the aluminum foil around the neck of the bottle. This acts as a lid . Make sure that everything is folded down nice and tight around the bottle. Check the candle and see if this wick is wet. And if it is not , turn it upside down for a minute . The oil will then come into this wick and saturate it. Be careful that your aluminum foil doesn't fall off. If your cotton wick is a little bit longer, pull it up a little bit . This exposes the wet part of the wick. Take your scissors and cut the wick down just a little. Light the candle . When you first go to light them it takes a minute because you have to get everything warmed up. Let it burn a little bit. Make sure to not use a thick layer of aluminum foil for the lid. The aluminum foil will heat up and cause problems.
