This project shows you how can take an old table fan and convert it into a simple ,cheap and easy to make homemade AC .
The materials needed for the this project are a table fan, 75 gallon per hour fountain pump with valve to control the water flow, multi purpose zip ties ,two 3/8th inch transparent PVC Pipe tube, 15 foot quarter inch copper tube,two hose clamps.
Unhook the locks if any and remove the screen of the fan. Take the copper coil and wind them across the rims of the fan .Secure them tight on the screen using multi purpose ties.
Add the screen back to the fan body and then adjust the two ends of the copper coil by bending them to face the back of the fan and secure them using ties.
Two 3/8 transparent vinyl PVC pipes are connected to the copper tube ends using hose clamps.
We attach the fountain pump to the end of the vinyl PVC tube that goes straight into our cooler. The recirculated water coming from the other end of the tube goes straight back into the cooler bag. The cooler bag is filled with ice packs and water. The water pump is submerged into the bottom of the bag with ice and water over it.
The water which is pumped with the help of the fountain pump gets recycled through the vinyl and the copper pipe and moves back into the bag, so you dont need to add more water .Both the pump and fan can be connected to solar generator in case if you want to make the system portable .
- How to heat your Garage by building a Super Insulated Radiant Floor Heating SystemThis project goes over the installation of a homemade radiant floor hydronic heating system for the garage. The radiant floor heating uses a pex tubing that is installed along the floor of your garage or room . Hot water is passed through the tubing which radiates the heat out into the room or space. The first step is to figure out what size pex coil tubing and how big of a water heater you would need . Also how many feet of tubing would allow enough heat to exchange into the concrete floor to sufficiently warm up the entire space. The total BTU/hour or heat required will be based on the square footage of your garage or room . We begin by levelling the ground and start laying down a vapor barrier .The vapor barrier is made out of 6 Mil Visqueen plastic PE film .The barrier keeps the moisture from under the ground to rise up to the surface of the floor. We then lay a mixture of sand and packing gravel before installing the two inch extruded insulating polystyrene foam on the floor and the perimeter. Four circuits of 800 ft half inch Pex tubing is stapled down on two inches of polystyrene insulating foam using a pex stapler. The eight tube ends are routed upto to a box from where it is connected to a manifold which is mounted on to the wall. The pex tubing with the supply and return tube is connected to the manifold with the help of a compression fitting . To check if all the connections are OK or if there is any hole or leak in the tubing, connect the manifold to a 100 PSOI air pressure gauge to do a pressure test. Five inches of concrete is then poured over the pex tubing circuits. Saw cuts of less than an inch are made into the concrete to allow for the shrinkage during the curing process. To insulate the pex tubing and to prevent water from entering into the floor, an expanding foam sealant is filled near the junction where the concrete meets the supply and return tubing near the manifold. The heating components of this system are mounted on a 4 X 4 square sheet of plywood. The heater has a rating of 7.2kW . The heater is flow activated which requires a circulating pump to pump water through it which then activates the heater based on the temperature setting. Two 120V fractional horsepower circulating pumps are used , one for running the water through the heater and the other circulates out through the pex loops. The pump has an inbuilt garden hose connector system used for draining. The hot water coming out of the output end of the heater passes through a pressure tank which removes the air bubble with an air release valve and prevents any water hammer to the system. This is further connected to the flow activated circulating pump for the heater with connections for filing and draining the system with the help of shut off valves. The water then comes down to a stainless steel manifold and then flows through the supply end of the pex tubing . The heated water splits into four supply loops at the manifold into the concrete floor. The water then returns back to the return end of the manifold through the other four loops of pex tubing and goes straight through another circulating pump and a Y strainer filter before circulating back to the heater. Two thermometers are connected at the supply and return end of the pipe to know the temperature difference of the outdoing water and the returning water. The flow is controlled by a thermostat and a switching relay that turns on the circulating pump . https://www.youtube.com/playlist?list=PLmHss3DBZUimsi9qV6RFJTUw6xh-P4B3Q
- DIY Video : How to get Gold from Scrap Computer parts that you can find at the junkyardThis 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. https://www.youtube.com/watch?v=8lXd85YfcvY https://www.youtube.com/watch?v=5c9Z5UYsUV4 https://www.youtube.com/watch?v=qkmhEGBjyMs
