    • DIY Video : How to build a Thermal siphoning rocket stove for an off grid water system. Clean and efficient burn
      This Video shows the build of a Thermal siphoning rocket stove for an off grid water system. The advantage of the rocket stove is a clean and efficient burn. This system uses 5 metres of 20mm annealed copper pipe, and though I designed the rocket in a J configuration, it worked better as a batch box. There is a vortex generator at the base of the riser and basically I was able to heat 200 litres of cool water straight out of the tap to 67 degrees Celcius / 152.7 F in 1.5 hrs.

    • DIY Video : How to get Gold from Scrap Computer parts that you can find at the junkyard
      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.
