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.
- How to convert an Old Ceiling Fan Motor into a 70W Efficient Single Phase Alternator GeneratorThis project goes over the conversion of an old ceiling fan motor into an single phase alternator .You can't take your standard AC electric motor and spin it and get an electrical current out of it unless you modify it. The ceiling fan motor used here will produce about 70 volts at one amp which is roughly 70 watts. Through a bridge rectifier we can get about 70 watts of power out of it. We start by pulling the cover of the fan. Inside we have a squirrel cage rotor in the middle and 6 coil windings around it. The coil windings are placed in clockwise and anti-clock wise directions inside the stator. Next we remove the circular rotor from the threaded shaft which is attached to it with help of a vice. We attach the shaft with the rotor through it within a vice. With the help of an extra piece of pipe to give leverage, we press them against the rotor and push it away from the rod and pop it off. We are replacing the rotor that we have detached from the shaft with a two inch hex steel bar . It has six sides that matches with the six coils from the stator. With the help of one eighth inch drill bit we cut a hole in the center of our hex bar. We put the hex bar through the shaft and fit them snugly around the threaded area. We take six one half inch neodymium or rare earth magnets and place them along the the 6 sides of the hex bar. We place them in such a manner that the poles of the magnets are opposing each other. For permanent usage, wrap this with a little bit of tape or glue so that they are held in place securely. We place our modified rotor in the middle of the stator and align them such that they fit in tightly. The outer screen is bolted back onto the motor. We can also add second set of magnets to increase the magnetic field of the rotor .This will also bring it closer to the coils on the outside and increase the overall voltage. To convert the alternating current generated by our ceiling fan alternator to direct current, we use a bridge rectifier. It has 4 poles, 2 for connecting our alternating current, the other plus and negative for DC power. https://www.youtube.com/watch?v=k-4IbLOZwnA
- 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 Homemade Atmospheric Water Generator . Produces/Extracts Distilled Water from the airThis 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 . https://www.youtube.com/watch?v=ksOr7lX_RVU
