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If you follow this process, you will be able to convert all of your old and outdated computer chips into pure gold that you can turn around and sell for money.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 DIY Passive Solar Thermal Water Heater. Simple and Efficient!!This project goes into the build of a passive solar thermal water heater using pex pipes and 4 X 8 plywood piece. The pex pipes are sturdy and tough , doesn't easily leak. This passive solar heater can reach upto 120 - 150 F on a typical sunny day. Instead of pex pipes, you can use cheap irrigation pipe for this project. The pex pipes are more stronger and durable . The heater can be used for heating your domestic water, space or room heating or just heating a swimming pool. The box that contains the pipes are made of 4 X 4 plywood . Four pieces of 2 X 4 pressure treated lumber are joined along the sides using screws to make the frame. We staple in some bubble insulation along the dimensions of the box . Since the insulation material is silver, it will reflect heat. To avoid this ,we coat it with a flat black paint to attract the solar heat. Two holes are drilled on the sides of the frame for the inlet end of the pipe where the cold water comes in and outlet end where the hot water comes out. The inside and the outside of the heater is painted flat back using rust-oleum high heat paint to absorb maximum heat from the sun. The first layer of half inch pex tubes or irrigation pipes are secured inside the solar heater box using half inch pex talon clamps. The clamps are installed on four sides of the box securing each loop of the pipe. The second or upper layer of pipes are secured in using zip ties. The total length of the pipe is 200ft. The pipe comes in through the inlet hole and goes to the outside on the first layer , all the way around and work itself inside .It then goes through the top layer and all the way to the outside and then exit through the outlet hole. The bottom layer pipes aren't going to be exposed to the sun as much but they still will be warmed up because the whole box is covered with lexan polycarbonate sheet. The top layer with the pipe that goes outside through the outlet hole will have the highest thermal BTU. A very inexpensive reed thermometer with a 4 inch stem is installed on the side of the heater using a half inch to three eighths bushing reducer . A 4 X 8 Makrolon Polycarbonate Sheet is placed on top of the heater box and secured down in place using a No 8 One and one fourth sheet metal screws ,finishing washers and rubber grommets. Silicon adhesives are used to seal the gap formed between the sheet and the box frame. The Solar thermal heater is placed at an angle of 20 degrees. This is done with the help of leg supports with dimensions 16 and 8 inches 2 X 4 pieces at both the sides. A 50 watt Renogy Solar Panel is also installed adjacent to the heater. This Solar Panel is for powering the bilge water pump. A 500GPH 12V bilge pump is used to pump the cold water through the pipes into the heater . In order to control the flow of water through the pump , it is connected to an speed control electric circuit box which has a relay, a buck boost converter,a motor pump speed controller, potentiometer and a switch. The pump is powered by a 50W Solar Panel .The negative connection from the panel is connected to the relay, the positive goes to the switch. The relay determines the voltage for the buck boost converter .It activates on a certain voltage we set and then powers the buck boost converter. The buck boost converter will keep a constant voltage no matter what the voltage the solar panel is putting out. It is then connected to a 15 amp motor pump speed controller and a potentiometer which is used to control the voltage of the bilge pump motor. The 12V 500GPH bilge pump is connected to the motor pump speed controller. In order to test the unit, we place the heater near a pool to heat it. The bilge pump is submerged into the pool which is then connected to the heater with help of a PVC hose. The output pvc hose is returned with heated water back to the pool. The water reaches upto 140 F based on our test. https://www.youtube.com/playlist?list=PLbzeOtpXZbGiesna9w4eLuGzWvCQah1-h
- How to build a Backyard Waste Oil Burner Powered Water Heater to produce Free Hot Water for your HomeThis projects goes over the build of waste oil powered free hot water heater for your home .This converts an old used domestic water heater to run on waste oil, engine oil or cooking oil. With as little as one liter of waste oil, this heater gives twice the heat output than a domestic electric powered water heater .As waste oil is free, this is more economical than running on gas or electric. The setup of this waste oil heater is very simple and easy. We have a waste oil burner that is placed under the domestic water heater. The burner is connected to a blower from a car. This blower is powered by a 12V battery charger . The burner is also connected to a drip feed waste oil pipe through a small pipe. The oil feed from a suspended tank, which gives it a gravity feed dribbles into the inlet pipe on the burner and it is simply blown into the burner by the force of the air from the blower. To control the oil flow ,we have a valve on the oil tank. The cold water comes into through the inlet hose at the bottom of the tank . From there burner just fires the heat up through the center of the heater as it would normally if it was gas fired. The hot water comes out from a outlet hose at the top of the tank. The waste oil burner is made out an old fire extinguisher bottle. The beauty of using extinguisher bottles is you don't have to worry about any flammable gases in them, and the metal seems to be quite durable. Make sure that the air and the fuel enter the bottle at a slight angle in order to create some swirling. This makes sure that the air and the fuel mix and will burn completely. And also that the bottle is kept hot so that the liquid oil will vaporize and the gas will burn. The inlet pipe for the waste oil and the blower is positioned at 25 to 35% of the way up to the bottle. The inlet pipe has a small bend in it so as to promote swirling within the bottle. This is important in keeping the bottle hot and self sustaining. The burner has a clean burn with almost no smoke. The output of the oil burner can be controlled by the amount of waste oil being dripped into the burner and by the amount of air blown into it. This oil gas burner is more powerful than a gas burner and the heat produced can overpower the heat sink threshold of the water heater . A vent line is installed on the system so that any build up pressure can be released. Apart from heating hot water , this set up can be used for space heating , pool heating or garage heating. https://www.youtube.com/watch?v=L4xq_GSjWLI
- How to build a Simple Homemade Wind Generator from Old Ceiling Fan ,Microwave Oven Parts ,Old TV Antenna and other free junkThis project goes over the build of a homemade wind generator built from random junk ceiling fan ,microwave oven transformer ,office chair, an old piece of a TV tower, and some random electrical stuff. The blades are also from an old ceiling fan .It is extended with some wood and fibreglass on it to make it stronger. A scrap piece of pipe is attached as a shaft to the hub of the turbine. An office chair frame which can move freely is welded to the pole/post of the turbine. This is welded to an old TV Tower. 4 magnets are glued on the hub. The frame of an old microwave oven transformer is cut .Its core is exposed and that is welded onto the brackets. The magnets pass over the transformer core and induction takes place creating electric current. We can use that current to charge a battery or to power lights or whatever. A multi transformer setup would generate more power. We hook up a rectifying diode to convert from AC to DC and some capacitors which can even out the voltage and give us direct current. Also a diode to block the current from the battery to go up back up to the generator. This set up can charge small batteries. A piece of sheet metal is welded onto the bracket of the ceiling fan. Four magnets are spaced apart and aligned along their respective poles in north-south directions and glued to the bracket using 2 part epoxy. To generate more wattage from the wind generator ,we use an old 120V DC lawnmower motor. Because we have multiple poles, we have magnets that are really close to the armature, this is a way better motor to use. The only downfall of this is that it has brushes, eventually it's the brushes are going to wear out, you probably get a few years out of it before you need to replace those. This motor would probably put out about 100 watts. https://www.youtube.com/watch?v=1k8aHz6xlXg
