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 Portable 420 watt Solar Power Generator . Very Detailed Video Instructions,perfect for beginnersThis project goes over the build of a 240W Solar Generator made out of an ammo box.The box is large enough to hold a 240 watt deep cycle battery. There are some basic tools that you are going to need to build this generator.Number one tool, you're going to need a drill. If you don't have a drill, you can find one at Home Depot, you don't have to spend a lot of money.Next thing you're going to need is a screwdriver. Next, you're going to need wire cutter, a wire cutting and stripping tool. And it's also got a crimper on there. To drill the holes in the metal ammo box,you need a step up drill bit which can drill different sized holes, using all the same drill bit.You will need a pair of pliers which might be handy when you are cutting and manipulating wires and then basic wire cutters which also we have on the pliers. The next thing that you're going to need is the heart of the generator, which would be the battery. Now this is a rayovac deep cycle battery.I recommend that you use a V max deep cycle battery. The next thing you're going to need is a USB port. This is a two port device, it's got a one amp outlet and a 2.1 amp outlet.You're also going to need a 12 volt outlet. Faceplate,blade fuse holder,terminal connectors,switch,self tapping screws,14 gauge 17 amp black and red wires. We use a 3 prong switch,one of them gold in color which is the negative terminal and the other two positive.Purpose of the switch is to control your USB outlet. And it's what turns the USB outlet on and off. The positive terminal on the USB outlet is first going to run to the positive terminal on the switch.Now the purpose of this switch is to break the electrical current when you turn it off. So positive terminal goes to positive terminal, then the second positive terminal on that switch goes to the positive terminal on the battery. So you've got a flow of electricity going from positive through this switch to the positive terminal on the USB port. The negative terminal on the switch goes to the negative terminal on the battery. The only purpose of that terminal is to control the LED light on the switch, it needs the both positive and negative electrical currents in order to turn that light on. Similarly for the 12V port,positive connector going to positive terminal going to the positive terminal on the battery. Lets start the build. Start with drilling holes for the ports using the faceplate.Get your marker and simply trace the inside from both the top and the bottom.So that's where your holes are gonna go. Now we want to find the exact centers that when we're drilling. Insert the 12V and the USB outlet into the holes which we have just drilled. Now these ports have a little ring that screws on the back. This is what holds it in place. Next thing we're going to install is the power switch and SAE Solar Power Socket and the voltmeter. To begin wiring our tabs batteries, you're going to need a few things. Number one, you're going to need a battery. Number two, you're going to need your quick disconnects. You're going to need your squeeze connector connector,your wire cutters and stripping tool and you're going to need black and red wires. Place the vmax battery into the ammo box.So we've got everything in place, we have our ports in place, we have our battery in place, we've got our switch in place, and our volt meter. We're gonna start by wiring the USB port. The positive connection of the USB port is connected to the positive of the switch which is further connected to the positive of the battery.The negative connection of the USB is connected to the negative of the battery. This switch will break the flow of electricity on the positive side and that's what's going to turn our USB port on and off. Using squeeze connectors,USB port negative terminal is now connected to the same negative terminal as the 12 volt port.Connect the positive terminal from the switch to the positive wire which is coming from the 12 volt port and continue that positive flow from the switch to the positive terminal on the battery . So we now have our USB port and our 12 volt outlet connected to the battery through the power switch. We've got the negative terminal of the USB port, going to the negative terminal on the battery, we have the positive terminal of the USB port.Then we've got a positive going from the switch to the positive on the battery all through quick disconnects. The negative terminal on the battery going to the negative terminal on the switch simply allows the switch LED light to turn on without this negative current flow of electricity. This the LED light has no power.So we want to give that light power by connecting to the negati.ve terminal on the battery. The negative of the Voltmter is directly connected to the battery and using insulated clamps,we connect positive wire that's already running to the switch for the USB port.Now we want to connect to the positive wire leading to the positive terminal on the switch so that the volt meter will turn on and off with the switch button. Next, we're going to cover the SAE port. We want to be able to have the battery charged when we plug this into a charger.Using the squeeze connector we connect the positive to the positive terminal of the battery.And then same thing for the negative, you would take your squeeze connector and connect to the negative. Lastly,A 15amp fuse is used to protect the generator from overloading. If you connect at current that is too high for their internal wiring to handle, the fuse will break and it will stop all electrical current from flowing.So if anything goes wrong in any of this wiring, it has to get past the fuse before it reaches the battery. So if there's anything that's that's overheating, or overloading this fuse is gonna blow and it's gonna protect your battery from being damaged . Next step is connecting a solar panel to your generator .We connect the panel to the charge controller and then from the charge controller to your ammo generator. A charge controller prevents the battery from overcharging. You don't want to get over 15 volts. Here we use Renogy 30 watt solar panel, this panel comes by default, with an SAE connector on the back. This is the same kind of connector that plugs into your generator. Connect the wires coming out of the Solar Panel into the charge controller.Next is connecting the SAE cord from the generator to the charge controller. So you just put the panel on the charge controller, the charge controller into the generator, and you're done. If you want the whole system to be portable, say you want to be able to take your solar panel and your generator camping, you want to keep things as simple as possible, you could actually mount the charge controller directly onto the back of your panel. https://www.youtube.com/watch?v=MVVRPUHUMUo https://www.youtube.com/watch?v=DW6C-ZjmRzo

- How to build a Super Efficient Outdoor Wood Stove Heater from an Old Propane BottleThis project goes over the build of an efficient outdoor wood burning stove heater out of an old propane bottle and some scrap metal from the scrapyard. This stove has secondary burn system that helps in combustion of any unburned smoke or fume inside .Almost little to no smoke coming from the flue pipe. The first step is to make sure that the old propane tank is empty. We take the valve at the top by removing the valve protector cage. Fill the tank with water and let it sit for a few hours before we drain the tank and start cutting top and bottom. With the help of a hole saw cutter ,we cut 100mm four inch holes at the top and bottom of the tank . The top hole is for the flue pipe to sit in and the bottom hole is for cleaning the ashes out. We also remove the bottom stand too. Next, we cut a hole for the door for the stove. This is cut as high up to the top of the bottle . The door is made of chequered plate piece . We fit a rectangular pyrex dish glass piece in the middle of the chequered plate that can withstand high temperature with couple of steel bracket pieces. The glass on the door helps us to see how the secondary burn system is working inside the chamber. The door is attached to a frame through hinges. The flue outlet on the top the tank is attached through a flange piece with holes. The door handle is made of a socket wrench. The wrench is bolted to the plate and a small metal piece is welded onto to the frame to which the wrench is pulled to close the door A deflector plate made of small holes is installed inside the stove on the top . We drill 8mm holes around the top of tank and put dome bolts across them. The deflector pipe sits on these bolts. The deflector plate stop the unburned gases exiting out the flue outlet pipe. This encourages the flame that rises, pass through the deflector plate holes into the secondary burn chamber that helps in better combustion. The secondary burn system is made of stainless steel pipes .The air intake section is long enough to get the air coming in to get super heated and move into two sections filled with holes. Since not all gases from the wood combust from the primary air intake, the secondary burn pipe ensures that the air gets super heated before exiting the pre-drilled holes and helps burn the unburned gases rising from the fire before exiting the flue pipe. The secondary air intake pipe coming out of the firebox is welded on the top of the tank with a flange piece. The primary air intake pipe that goes under the door frame is made of a two inch coupler and threaded damper disc. A small metal piece is welded to the coupler with a hole in the middle. The damper disc screws in through the hole that allows us to close and open the intake .
