This project goes over how you can easily refine and smelt Gold from Old Scrap Computer Memory Chips
The materials you need for this project are some Muriatic acid,Hydrogen peroxide,Urea,Sodium Metabisulfite,Nitric acid.
Cut the little gold fingers from the chips using a heavy duty scissors.Get right to the edge of the gold and cut that off.
Okay, now that we’ve got all the fingers cut off of our memory chips, we put them in a plastic container.And in equal parts, we’re going to add our hydrogen peroxide and our muriatic acid.
Let it sit for 24 hours.If you can put it out in the sunlight during the days or the day time and then bring it back in at night,that’s ideal.
Drain the mix through a coffee filter and into another plastic container.
And then we will rinse distilled water in these fingers and go through each one of the fingers and make sure there isn’t any gold left on them.
Filter the Gold granule filled water using a coffee filter,add sprinkles of distilled water.This helps to move those tiny granules around.
Add some nitric acid and muriatic acid to the gold mix and put it on a hot plate or a coffeemaker and turn it low.Let that gold dissolve into the mixture.
Strain the mixture through a coffee filter and rinse them though distilled water and put it on a burner.
Now we are going to add Urea. Basically what the urea is going to do is neutralize the acid, we’re going to start with one tablespoon of this, and then keep adding it stops bubbling that’s all the acid neutralizing right there.
Now we’re going to add our sodium metal by sulfate, we’re going to add two teaspoons of that. And that’s going to turn all that liquid gold into metal.
Let the mixture sit overnight and let it settle down.Everything on the bottom is going to be our gold, and it’s going to be ready to smelt.
Heat them till its melted and upon weighing its around 1.91 grams.
Next step is testing the gold we have produced and see how pure it is. We use different acids based on the karat.If there is no reaction from the acid test,ifit’s not changing colors, and it’s not dissolving ,then we have a pure 22 or 24 karat gold here.
If you follow this process, you will be able to convert all of your old and outdated computer chips into pure gold that you can turn around and sell for money. It’s a great way to salvage your old electronics and get some value out of them.
- How to build a Homemade Micro Wind Turbine for under $50 that can be mounted anywhereThis project goes in the detail on how to build a mini wind turbine..The wind turbine is a nice addition to your solar generator system for times when it’s cloudy and you are not receiving as much sunlight as you normally First step is to build some cheap PVC blades, what kind of motor we're going to be using and how we're going to attach this to the motor. We are making six blades or rotors here.What we want to do is we want to cut our PVC pipe to length first. Once you've got it cut to length, then you want to take your your straight edge again and and Marco line down the center and cut it in half. Make sure that you do that on both sides. One on this side, one on this side. And that they're perfectly in the middle so that you'll get two even sides. We need to cut a small little block down at the blade end, where we are going to put a drill hole and put a screw through it so that it attaches to the hub.On the top of the blade, we're going to cut away some of the material to resemble a swept wing, kind of at an angle. These are 14 inch long blades that is attached to the hub using set screws attached to the motor. The 12V motor used here is a 300 RPM geared motor which would be its maximum speed and it produces 600 milliamps when its fully loaded. The motor is placed inside a One and half inch PVC pipe ,another PVC Tee is connected from where the wires will down to the bottom where another 7 foot pipe that act as the tower or pole. The end of the pole goes into a shower drain which is then attached to piece of wood that acts a solid base. For the YAW system at the back end,a tail vane is made of a cheap flashing material that is bolted between an 8 inch piece of PVC.Put a hole through the middle of it with a bolt in between so that it can't move anywhere. We use an an old OSB for the base, size is about seven inches square. And then I just have a piece of treated lumber on the bottom. It's attached to this ball bearings so it can spin around. The Shower drain PVC is placed in the middle through some ball bearings. Route the wiring down through the hole for to connect to the charge controller. Next step is the wiring through the piping.We just need to connect these terminals to the appropriate sides of the motor. https://www.youtube.com/watch?v=6UZ2WtXlVoc https://www.youtube.com/watch?v=fjHW78bMUoY https://www.youtube.com/watch?v=c7a9RSzZKcE
- DIY Video : How to build a Simple Woodgas generator for small electric RV generatorThis is the build of a simple Wood gas generator for small 5HP electric generator.This is made from simple materials that can be easily found around your home. The main generator here is a 20 gallon garbage can inside I have a wine cooler and inside there I have hung a small steel bowl. It's just connected up to this very long aluminum duck line to my filter and my filter has been filled with wood pellets to also serve as the fuel. . Then the outlet line goes over to an air inlet port.When you burn the gas you have to add air and this is the valve I've designed to allow that. It goes all the way to the RV Gas engine.You can cut off the fuel by using a wire to cut off the fuel pump. We use a 20 gallon garbage can as the filter.So first I use a quarter inch drill to put two holes in here and then I've enlarged it with a nibbler.Put a harbour wire down in the can where the filter medium is dumped. I use pine wood shavings as a filter medium.Use about 1/3 to fill up my 20 gallon. The reactor is basically constructed out of a stainless steel thermos, which is a central cylinder that is double walled and it has like a one inch opening at the bottom. And below that we've just hung a steel mixing bowl that we basically drilled a lot of holes into and then hung by these three chains that you have riveted in. And then we just connected it with a simple 20 foot ordinary dryer duct. The reactor is filled up some wood pellets ,we have stretched out the hose, this will cool the gas into the improved 20 gallon filter. And I'm going to be driving this with a small air mattress pump. And what I've done is I've rigged myself a dimmer control here so I can actually control the speed. https://www.youtube.com/watch?v=5WLuZP71dc0 https://www.youtube.com/watch?v=cLUNw4knlkc https://www.youtube.com/watch?v=uz93cb0zPlk
- How to build an Off Grid Hydraulic Ram Pump that uses no electricity to pump water .Water is one of the most important resources you can have and to get water to the highest point in your property, so that you can store it and water your gardens and your animals and your orchards is incredibly valuable. This project goes over the build a water pump that can pump water uphill with no other external source of power except for the water flowing into it. If you have got a piece of land with an abundant source of water like a pond or a creek, a ram pump lets you get that water to a tank or a location at a higher elevation without using no electricity or fuel. A ram pump is essentially two one way check valves, one called the waste valve and the other called the delivery valve. To get it started, you just momentarily open the waste valve to allow water to flow. After that it's working on its own to pump the water uphill above the elevation of the source. The ramp pump works by the principle of water hammer. As the waste valve opens, water flows into the pump and immediately out the valve. But as it picks up speed, the flowing water eventually forces the waste valve to slam shut. Now the water is stopped in the pump, it had kinetic energy, but now it doesn't. That means that kinetic energy was converted into pressure. Slamming a valve shut converts all the kinetic energy nearly instantly, creating a huge spike in pressure which opens the second check valve and forces water entering the pump into the delivery line. An pressure tank is included in the pump to smooth out those sharp spikes and pressure and provide a more even flow rate out of the delivery pipe, reducing wear and tear on the pump components. Here we use a PVC cylinder as the pressure tank. As the delivery pipe is opened, it will allow a constant flow of water as the pressure builds. If you open the valve too quick, this will hold a certain amount of pressure in it so that the pump doesn't stop due to pressure loss. To get the water to the pump somehow from your source, you need to have a tube or pipe. This pipe is a called a drive pipe. This need to have head pressure or drop in elevation. The drive pipe has same size as the waste valve. The more rigid the material, the more efficient your pump will be. You can use steel or PVC pipe or flex tube. To get the water to our desired destination, we are going to have to have something called a delivery pipe. Here we are using garden hose as the delivery pipe. Here are the steps to assemble a one and quarter inch hydraulic ram pump. The parts you need to build this pump are : Six one quarter close pipe nipples - This allows the components to be screwed close together and not have any extra gap between. Two three quarter pipe nipples 2 One and a quarter ball valves 3 quarter threaded union 2 One and a quarter PVC union 2 threaded PVC tees - threaded on all 3 sides A threaded spring check valve - This has a spring on the inside. That allows water to flow through one direction and not the other. A bushing that goes from one and a quarter down to three quarter. A brass or stainless steel swing check valve - This is threaded on both ends. And inside there is a little lever that closes on a swing motion. Teflon pipe tape to make sure things are tightened up and couple of wrenches. The first step in the pump assembly is to take the Teflon tape and put it around these one inch and three quarter pipe nipples. This is done in a clockwise position such that whenever it is time to actually screw components onto this, we want to make sure that they do not unscrew or remove the Teflon tape. This pipe tape will allow the components to screwed together in a more fluid manner. And it helps to create a better seal in the components. Next step is take your one and a quarter ball valve and a pipe nipple and thread that together. Take the one and a quarter union and connect it to the other end of the taped nipples. Connect a tee to this unit with the help of another pipe nipple. Next is attaching a spring check valve to this unit. You need to make sure that the flow is pointing away from the components we just put together. There's an arrow on these that distinguishes the flow direction. Connect another PVC tee to the valve through a nipple. A threaded bushing is going to go on the end of that second tee. On that three quarter bushing, we are going to put one of the three quarter pipe nipples. From that pipe nipple, we are going to put the other three quarter inch union. A three quarter ball valve is connected to this end through another pipe nipple. We connect the swing brass/stainless steel check valve to the first PVC tee with the help of another pipe nipple. When connecting the check valve, make sure that the door or flapper is going to fall open from gravity. So it is going to screw on to this pipe nipple with the door hanging open. The second PVC tee is connected to the pressure tank with another pipe nipple. Make sure that both tees are facing in the same direction. To build the pressure tank for the one and a quarter pump, you need a four inch PVC schedule 40 pipe , four inch coupling, four inch socket to one and a quarter threaded bushing , a four inch cap , bicycle inner tube. Take your angle grinder and cut a 17 inch long pipe from the four inch PVC schedule 40 pipe .Once the pipe section is cut, it's time to assemble the pressure tank. Coat the inside of the coupling with a PVC cement and stick our 17 inch pipe inside .Make sure it is real snug in there . The other side of the coupling is connected to the threaded bushing. Next step is to insert the bike inner tube into the pressure tank .Grab it from the underside and pull it enough that we can attach my pump to it. Start filling the tube with the bicycle pump. Pump until the whole tube seems tight. Put the cap back on the top and seal them tight using pvc cement. The last step is to attach your pressure tank onto this threaded nipple that is connected the second PVC tee on the pump. Next step is installing the ram pump near the water source .This one and quarter inch pump requires around eight gallons per minute to operate. The amount of water that you get at the top is increased as the pump size goes up. So to start the pump, first you need to close the ball valve for the delivery pipe and make sure the ball valve for the drive pipe is opened. You need to just push the waste valve down until all the air inside the drive pipe is out. Water comes down this drive pipe and slams against the check valve to shut it down . It creates a pressure wave that gets shot back up the drive pipe .If the pressure wave finds an air pocket ,then the pump will stop. Start priming the pump by opening the valve manually couple of times until the pump starts to work on its own. After the pump has been running for a minute or two, you're gonna open up your delivery pipe valve out because the pressure tank now has enough pressure in it to push water uphill. https://www.youtube.com/watch?v=K8Fy__ThqpQ
