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If you follow this process, you will be able to convert all of your old and outdated computer chips into pure gold that you can turn around and sell for money.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 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
