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If you follow this process, you will be able to convert all of your old and outdated computer chips into pure gold that you can turn around and sell for money.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.
- DIY Video:How to build a Super Efficient ,Multi Use Homemade Ammo Can Rocket Stove. Inexpensive,Portable and Leaves no smoke….This project goes over the build an efficient clean burn multi use ammo can portable rocket stove . Easy to build , small ,portable , leaves no smoke. The reason it is smokeless is because it uses a secondary burn system . Also can be used as a cooking stove. The first thing you need is an old NATO ammo can. Remove the rubber seal that sits around the top of the can and replace it with a stove rope. The stove rope gets compressed when you close the stove with its closing mechanism and the smoke wont escape from around there. One the top, we have the flue made out of 2 inch stainless pipe .It has two sections, upper section slides onto the lower section. In order to build the flue, we take the top of the ammo can, then place the pipe on top and draw around it that gives the circumference. Take a grinder and simply cut across the shape. In order to get a smoke tight seal, we wrap some stove rope around the flue area we just cut and then insert the pipe and use a jubilee clip around the bottom and compress it against the stove rope. Once this gets up to working temperature, it draws cold air in from down below and expels it out at the top. So all the smoke from the stove gets drawn upwards. We use 2 turnbuckles as a stove door closing mechanism. There are two closing mechanisms on this door. One is a quarter turn latch. So you rotate it, the door opens ,you close and then you rotate it and it locks the door closed. Another mechanism is using a long piece of metal. You can turn each of these a quarter turn and that locks the door extremely tight to fit these turnbuckles . The stove baffle plate is made out of 0.8mm thick thin steel. To make it, measure it up against the stove and bent the steel into that shape. The baffle helps in generating more heat as it keeps the air from escaping the burn chamber. A secondary pipe made of galvanized steel pipe comes from back of the stove and comes across the stove through a small hole. The pipe has been drilled with small holes. When the stove is in operation, this draws in cold air from outside, it gets pre-heated on the way down across the burn chamber. And then the pre-heated air rises and is expelled naturally through these holes. And since this pipe is just under the baffle plate, it reignites the smoke and the smoke is burnt on the way across the upper section of the stove. The stove is insulated using fibreglass and stainless steel from three sides inside, helps in efficient secondary burn. You just need enough insulation to get the temperature high enough to get secondary burn. If the whole stove is insulated then the heat would dissipate through the flue instead. The bottom of the stove is insulated using half inch rockwool and on top we have some chicken wire that stops the burning fuel from sitting on the bottom of the stove and being starved of oxygen. It allows the oxygen to get underneath and burn all the way around the wood efficiently. The primary air is drawn in through an air intake at the side of the stove. To attach it to the stove, bend the pipe around the side and place a jubilee clip and stove rope around to insulate it. So when the stove is in operation, you can add sticks, twigs, pellets or anything you want without opening the door. https://www.youtube.com/watch?v=BUz6Ai2yAxE Burn Video : https://www.youtube.com/watch?v=Vd7RFwyQxrI

- How to convert an Old Ceiling Fan Motor into a 70W Efficient Single Phase Alternator GeneratorThis project goes over the conversion of an old ceiling fan motor into an single phase alternator .You can't take your standard AC electric motor and spin it and get an electrical current out of it unless you modify it. The ceiling fan motor used here will produce about 70 volts at one amp which is roughly 70 watts. Through a bridge rectifier we can get about 70 watts of power out of it. We start by pulling the cover of the fan. Inside we have a squirrel cage rotor in the middle and 6 coil windings around it. The coil windings are placed in clockwise and anti-clock wise directions inside the stator. Next we remove the circular rotor from the threaded shaft which is attached to it with help of a vice. We attach the shaft with the rotor through it within a vice. With the help of an extra piece of pipe to give leverage, we press them against the rotor and push it away from the rod and pop it off. We are replacing the rotor that we have detached from the shaft with a two inch hex steel bar . It has six sides that matches with the six coils from the stator. With the help of one eighth inch drill bit we cut a hole in the center of our hex bar. We put the hex bar through the shaft and fit them snugly around the threaded area. We take six one half inch neodymium or rare earth magnets and place them along the the 6 sides of the hex bar. We place them in such a manner that the poles of the magnets are opposing each other. For permanent usage, wrap this with a little bit of tape or glue so that they are held in place securely. We place our modified rotor in the middle of the stator and align them such that they fit in tightly. The outer screen is bolted back onto the motor. We can also add second set of magnets to increase the magnetic field of the rotor .This will also bring it closer to the coils on the outside and increase the overall voltage. To convert the alternating current generated by our ceiling fan alternator to direct current, we use a bridge rectifier. It has 4 poles, 2 for connecting our alternating current, the other plus and negative for DC power. https://www.youtube.com/watch?v=k-4IbLOZwnA
