- DIY Video : How to build a simple Off Grid Refrigerator using a 5 gallon bucket . No Ice Needed !!This project goes over the build an off grid survival fridge using a five gallon bucket . It has a peltier cooling module on the top. So no need of refrigerant or ice cubes. The materials you need to build are as follows. A 12V 12A Thermoelectric Peltier Refrigeration Cooling System unit from Amazon, a 5 gallon bucket , 4 gallon Styrofoam liner from Home depot. This refrigerator works by the principle of peltier effect. The Peltier effect shows that a temperature differential is created when a DC current is applied across two different materials .The peltier unit is made of using two thin ceramic wafers with a series of n and p semiconductor materials sandwiched between them. The ceramic wafers add rigidity and provide the necessary electrical insulation for the module. The n type semiconductors have excess electrons, while the p type have a deficit of electrons with one n and one p making up the junction couple that creates the thermoelectric effect. When a DC current is applied to the circuit, the thermoelectric module can work as a cooler or heater depending on the direction of the current. A thermoelectric cooler or tech transfers heat from one side of the device to the opposite side against the temperature gradient creating a cooling effect. We use heat sinks and CPU fans on the peltier chips to radiate and lower the heat generated on the hotter side and move the cooler air into the bucket from the cold side. The peltier setup in this build uses two 12V 92mm fans on the hotter side glued to a large 200m X 100mm Aluminum heat sinks, two 12v 5.8amps peltier chips are glued under two 40mm heat sinks using thermal paste. 2 40mm fans are also attached to the heat sink. The Styrofoam liner is inserted in to the five gallon bucket . Two small rectangular cuts are made on the lid of the liner so that the heat sinks fits inside there and gets good airflow around the edges. We cut a rectangle on the top lid of the bucket to allow the peltier module to sit in. Small vent holes are drilled on the sides of the lid using a standard quarter inch drill bit so that no hot air gets caught between the bucket lid and the Styrofoam lid. Cut a small notch in the bucket using tin snips so the wires from the peltier units will come out without getting pinched under the lid. You can hook this unit to 100 watt solar panels straight , 12 volt deep cycle battery, 12 volt transformer to the wall, or you can use your car CIG lighter. This unit can drop the temperature inside the bucket from 81 to 47 degree Fahrenheit in minutes. https://www.youtube.com/watch?v=qj2PBnCdRgM

- 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
