This video shows the build of a Simple Homemade Air Cooler using a Used Tropicana half gallon Juice carton.This desktop sized unit works very well and couldn’t be simpler to makeThis is made using made a “half gallon” (specifically 59oz./1.75L) juice carton, 80mm DC fan (blue-lit), 1.5″ PVC pipe coupler and a 3/8″ square wooden dowel.It holds about 2 ice-cube trays worth of ice at a time (and it has a built-in drain! so as ice melts you can drain the ice-water into a glass for a cold drink).
Thisonly took me 10 minutes to make it. cost about $8.50.This can be run using a 12v solar panel (2.4 watt or higher), a 12v battery or wall current (just use an ac to dc transformer that puts out 12vdc).
- How to build a Simple and Efficient Homemade Garage Fan out of Old Furnace BlowersThis video shows the build of a Homemade Garage fan made out of Old Furnace blowers that is easy to make and really efficient.Once you try one of these you'll never use a box fan again. These fans are designed to run with constant restriction. So you need to recreate this when used out in the open by blocking roughly 25% of the air intake or output. If you don't restrict the airflow the motor will pull significantly higher amps than it is rated for and will overheat/burn out. If you want to be scientific you can look at the side of the motor and read the rated amps. Then with a load meter hooked up, run it and block off the air flow until the amp draw drops to or close to the rated amps.Centrifugal fans are amazing at moving a large quantity of air and the output can be ducted unlike axial.
- How to build an awesome Drill Powered Winch .Lift a Car or other Heavy loads effortlessly using a simple Cordless DrillThis video shows how a simple Cordless Drill can effortlessly lift or move heavy loads. Definitely beats a Come Along.The winch in the video was purchased from Harbor Freight.With a snatch block this will lift 4000lbs which will pull a 20,000lb vehicle up a 10% grade.A snatch block is a really neat thing. By taking the cable out of the winch and through the pulley of the snatch block, then back to the winch it doubles the pull capacity. It also halves the speed of the item being pulled/lifted but it is a worthwhile trade off. You can keep adding pulleys and running back and forth to reduce the strain on the winch.You will see that a cordless drill lifting a car off the ground is pretty damn impressive
- How to build a Simple Survival Water Distiller using BottlesThis video shows the build of a Simple Solar Water Distillation System for survival/SHTF situations.This is made using 2 clear (plastic or glass) bottles and glue (or tape).Fill one bottle with dirty/or saltwater,then connect the second bottle and set in the sun.Within a few minutes the water begins to evaporate and the other bottle collects the clean distilled water vapor.make sure the bottles have an airtight connection. prop up bottles at a slight angle so as the dirty/or saltwater starts to evaporate - the max. amount of water vapor will travel up to the higher collection container. works best in bright sun.
