- How to Generate Emergency Off Grid Power using a Car Alternator and an exercise bike.This project goes into the build of a DIY pedal powered generator out of an old car alternator and a bike. This generator is useful for powering your devices and gadgets in case of an emergency or grid down scenario. The materials you need to build this generator are bike, MDF for base plinth, magnetic trainer stand for bike, Alternator, drive belt, 12V battery, cable connectors, 12V socket, multimeter, screwdriver, insulation tape. The rear end the bike and rest of the components are mounted on a one inch thick MDF board. This has a good amount of stability that keeps it away from moving around. We add an extension bit on the front. The extra height there just compensates for the fact that the back wheel is in a stand. The alternator is mounted nice and secure onto the base using brackets. Bolts connect the alternator to the brackets and screw the brackets down to the base. Once you are pedaling, and you have got electrical load in the circuit, there is quite a bit of force pulling the alternator forwards. So it does need to be really securely bolted down. Make sure that the wheel of the bike is in line with the alternator pulley .With any wheel, we have rim bed and the rim walls. Here what we need is a drive belt that fits purely in the rim bed. Make sure you measure the internal width of the rim bed . Also measure the width and depth of the alternator pulley grooves and get a belt that fits accordingly . Also make sure you have got a belt that is long enough because a typical drive belt that is used in a car is not going to be long enough because it is only made to go around a pulley on the engine. The car alternator used here has three wires coming out of them .It has a main power thick output wire, it supplies main power to the devices. Then there is two small cables, one for voltage sensing and the other for field coil ignition. The voltage sensing wire goes straight to the 12V lead acid battery in our case. To get the alternator generating power you first need to apply a small voltage through the field coil and that is because an alternator doesn't have any permanent magnets in it. The way that any generating device works is moving either electrical charges through a stationary magnetic field or moving a magnetic field around a charge. So the field coil inside the alternator is attached to the field coil ignition cable, and putting a voltage generates the magnetic field, which enables the alternator to generate power when you turn the shaft via the drive belt. You don't need to keep applying a voltage to it as it's running, because it will generate its own power. The negative from the alternator is connected to the negative of the battery. The positive connection from the alternator is connected to the positive of the battery. The third connection coming from the alternator is the field coil activator .This is connected to a switch .The connection goes back to the alternator to active the field coil. A standard cigarette lighter socket is connected to the battery terminals. It will draw power off the battery first, and once you start charging power, because the alternator is connected into that, it is going to draw it from the alternator, and the alternator will simultaneously power whatever is connected into that socket, and recharge the battery. The alternator used here has voltage tolerance of 11 to 14V . A Modular splitter is connected to the cig power socket to charge multiple devices. Make sure that the plug comes with a fuse or whatever you plug in needs to be rated to the right power for what you are going to charge . To run alternating current devices, we connect a 150W Power inverter to the circuit. The alternator actually generate alternating current. But its got a rectification circuitry built into it, which changes it to DC. The inverter changes the the DC output from the alternator to AC. Finally ,we add a master switch that switches the battery on.The Power switch stops any drain from the battery through the field coil . The switch also connects the multi sockets that charges various devices. It isolates the battery from the circuit. It isolates the alternator from the circuit, and it isolates the remote switch and the battery from the field coil completely. The AC generating device like an alternator have a minimum speed of operation in which they are stable. So do check for your alternator, what is the recommended minimum speed for it. If you spend it below that speed, what happens is because of the way it works, you get a periodically varying force which acts as a resistance to your pedaling. https://www.youtube.com/watch?v=_Hx1ptv6RKI

- DIY Video : How to dig your own shallow water well for the gardenThis project goes over the instructions on how you can dig your own shallow hand pump water well using simple tools and save a lot of money. Before digging the water well, you need to know the ground. You got to have the right soil for this system to work. If your soil type is silt, clay, sand or loam, then its ideal .In our case, we have the first 10 or 12 feet of fine glacial silt and below that there is glacial deposits of river gravel. The first step is to dig a hole for the well casing. The tools you need to dig the hole are six inch post hole auger , three quarter inch extension pipe with coupling at the end and couple of wrenches. Once you have spotted the area where you want to dig the well, you start by applying downward pressure on the auger by twisting it. It screws itself into the earth filling its basket with material. When it's full, you pick it up and dump it aside or in a wheel barrel. Sharpening the auger can help it cut through tree roots but it will not stay sharp long. It is important to do your best to keep the hole centered. Once the bottom is reached, we pull out the auger and remove the basket from the handle and insert one of the extension using the pipe wrench. The next part is getting the casing down the hole. For the casing we are using a cheap and readily available six inch PVC sewer pipe. We use a rasp to smoothen the end of the pipe so that it fits a cap . A round piece of PVC flat stock is bolted and glued on top of the cap using a PVC glue. This becomes the mounting base for the pitcher pump. To get started with driving the well point, we need a long piece of 10 foot pipe and a sandpoint, a couple of drive couplings. The drive couplings are steel rather than cast which makes them stronger. But most importantly, they have that small diameter so that they can slip down inside, making them not much larger than the diameter of the sand point itself. The sandpoint is made of perforated stainless steel and a cast iron point at the bottom. We connect the sandpoint and 10 foot pipes using the couplers and some Teflon tape. Now you don't want to hammer on your drive point or any of your fittings without them being quite tight because you need those extra threads to spread the load. We drive the whole thing with a homemade post hole pounder which is a gooseneck trailer hitch ball welded into a piece of pipe. We insert the sandpoint with the extension into the well casing and start drilling by hand. We are gonna find out how far down that water is by dropping a string with a bolt tied to it to the very bottom. We finally attach a black ABS suction by sliding it down into our pipe .Then we cover the pipe with our PVC casing . And once the casing has been firmly tamped down, we will pack around the casing and tap that into place. The final step is to install the pitcher pump and prime it by add some water. The top cap is installed on the casing opening and the pump is bolted to the top of the cap. Priming the pump simply entails pouring a little water in that top basin. https://www.youtube.com/watch?v=9mG4j4I13y4 https://www.youtube.com/watch?v=6p5ked9gKuQ https://www.youtube.com/watch?v=334mj68JU0I
