DIY Video : How to build a 100W Super Bright LED Flashlight using a PVC pipe and Dead Laptop Battery

    This video shows the build of a super bright 100W LED flashlight in PVC pipe housing.Main parts bought from ebay. The battery of this flashlight came from 18650 lithium cells removed from dead laptop batteries.The other materials required for this build are 100W LED COB chip,100W LED Reflector, lens, lens bracket kit,DC to DC boost converter 250W,DC to DC step down (buck) converter.Some parts bought at local electronics or hardware store.Rest all stuff had lying around.The other video shows the build of the 22V 6Ah battery pack from dead laptop batteries.

    • DIY Video : How to build a Thermal Vacuum Water Pump that needs no electricity and has no moving parts!
      This Video shows the build of a Solar Evacuated Thermal Vacuum Water Pump works by harnessing the energy of the sun in the day time and then uses the cold of night to create a vacuum in the system that is used to pump water. This is a working prototype of an idea on how to pump water from stagnant water sources cheaply using no moving part.By using the sun's energy to generate both a pressure and a vacuum cycle we create a very efficient water pump, that has only two simple moving parts. This pump was able to move one gallon every cycle to 8 feet high, by creating artificial day/night cycles the pump could move about 1 gallon every 30 minutes of sunlight, or about 12 to 20 gallons a day.

    • How to build a Homemade Multi Use Water Purifier that uses no electricity .Works as Water heater and stove burner too….
      This project goes into the build of a simple and cheap two stage DIY water filter.Also doubles as a stove burner. The materials needed for this build are some bricks,bottles,copper coil,activated carbon,sand,gravel I got the sand and activated carbon water filtration part on the far left. In the middle, I've got it heated in a copper coil running on isopropyl alchohol. The purified water is coming out on the right side. The first step is to make the 1st stage filter. We take a 2L bottle cut in half, drilled a quarter inch hole on the bottom and drop in a couple of cotton balls and pack it in there. Next step is to add the activated carbon,sand and gravel.Rinse all of them before adding . Align the bricks and place the cans on top. Place a small tin with the isopropyl alcohol inside the middle can. A copper coil is inserted into the middle can and connect between the first can and the water bottle. Add the sand mixture filter bottle on top of the first can below the copper pipe. For the first can the one that holds the activated carbon filter,just remove the label and drill one small hole at the bottom. Then for the second cam that holds the copper coil, you cut down the top, take about a third of circumference off and cut about two thirds of the way down. Then put one small notch on the top and a hole down below for the coil. To make the copper coil just wrap it around from top to bottom in a smallcan, push the can out and leave about a foot on either side. Notice I added a couple of bricks and pointed the end of the copper tubing down directly into the can so we won't lose hardly any water and make sure to drill those steam vents so the pressure doesn't build up. Make sure to drill vents on the bottle so that the pressure doesn't get build up. Pour the alcohol under the coil and fire it up. Just put a little in ,you don't need too much. A full glass of water gets purified in three to three and a half minutes. This gravity fed two stage water filter should take care of pond water stream water swamp water, just about any water you can think of. Don't try using this without the heavy sand gravel and activated carbon in there or the water will backflow and it may spray out. An easy way to store this filter when you're not using it is just save the bottom half of the two liter bottle you cut in half and drop the filter in it ,holds it perfectly. This cheap 2 stage heated oil water purifier can also be used to both purify water and cook at the same time.
    • How to build a Homemade Archimedes Screw Turbine using PVC parts to generate Off the grid Power from a flowing river or stream/creek
      This project goes over the build of an Archimedes Turbine that can generate off the grid power from a flowing river or creek. This is basically a screw that turns when water passes through the pipe. You need a 5 foot farming auger to build this. The farming auger is put inside of a 6 inch pipe and placed in the creek at a certain angle, water would pour into the auger and that water would weigh down that auger and turn it. And so as it turned, it would turn a shaft that is attached to the end of the pipe and run a pulley system with a motor to generate electricity. We take an old belt sander and shave some of the edges to make it smooth and rotate without any friction inside the pipe. We use an angle grinder to split the pipe down the middle and use the separator nuts to kind of give more space in the pipe. Make sure you don't split the pipe into two. Open up enough space on the top by heating the PVC and clamp 2 spacer boards on either side and stretch the opening by using a C clamp. 2 three quarter inch boards are bolted using carriage bolts on either side of the pipe which gives us enough room here to get the auger installed. Allthreads of size eight and quarter inches are put through the boards and secured in place with the help of some washers and non locking nuts.
