I’m going to show you how to make an electric generator for your home using a few simple household items. It’s so easy! After this, you’ll be able to power all of your electronics and charge your phone in the event of an emergency.
Building a Generator With an Alternator to Power Your Home
The following guide illustrates how to build a generator from scratch. It uses an alternator as the power source and a car battery as the energy storage unit. This way, you can keep your electronics pumping even if you’re stuck in a power outage or disaster situation.
To make this work, I used one of those items that are usually sitting in your garage and become very useful when the power goes out: an alternator from an old car. You can pick one at a junkyard or buy one online.
Step 1: Disassemble an alternator.
To build the generator, you first need to take apart the alternator and discard everything but the stator, backplate, and bottom bearing cup.
The rotor is useless for our purposes so it’s best to toss it in a scrap metal bin at your local junkyard – if you happen to have one nearby. The rotor is pictured below but for now, just look at all that free copper!
Be sure not to damage any of the wires attached near the brushes or else you could cause a short circuit. I recommend covering them with insulation tape before moving on.
Step 2: Drill two holes into the backplate.
You’ll want to drill through both sides of the backplate for this step. Start small and work your way up in size until you can just fit a bolt through the hole. The bolts are what you’ll use to mount the backplate onto your wooden board later on.
Step 3: Screw two eyebolts into the stator assembly.
The eyebolts will be used for mounting purposes so that you can attach everything to a board or other structure if desired. You could also make an arched frame out of wood to hold everything together but I did not do this because I was lazy and wanted it mounted on a vertical surface behind my desk.
You might want to use locknuts here, otherwise, they’ll come loose after about five minutes of generator time! As long as they don’t come completely loose, though, everything should still function fine.
Step 4: Screw the stator assembly onto the backplate.
After you take apart your alternator, discard all other components except for the rotor and stator (the stuff that spins). Then screw them together like shown below or use bolts to hold it all in place. There are holes on either side of the backplate where you can mount this step securely using eyebolts as I did.
Assemble everything else before attaching it to the board so that you have more leverage. The bearing cup goes on last because it’s large and heavy – not fun to try and lift over a surface once everything is together! You may need assistance… or at least something to stand on.
Step 5: Attach the stator assembly to a board and hook it up to your car battery.
Here’s everything all mounted up and ready for testing! Use bolts or screws at each connection point so that you can easily disassemble everything if something goes wrong or needs adjusting.
I used an old piece of plywood I had lying around for mounting purposes but anything flat will do. The important thing is to make sure that it doesn’t interfere with any moving parts like the bearings in the bearing cup (which may need lubrication) or the brushes which are what you’ll be using to charge your batteries.
Once everything is mounted, attach alligator clips to each of the connections on the stator assembly. The order doesn’t matter but I would avoid putting them directly next to each other (in parallel). Then connect one end of your jumper cables to your car battery and let the sparks fly!
You should see a blue glow from the brushes as the rotor spins. You can use this to calculate your generator voltage by measuring it with a multimeter and multiplying your battery’s voltage (12V, 24V, etc.) by that number.
Step 6: Add an LED to the rotor.
You can see here that I’ve mounted four LEDs in between two insulated standoffs. They light up in sequence as the alternator spins about, creating a hypnotic effect! You can add more or less of them depending on how many volts you want the generator to produce. Just make sure they have their positive and negative polarities in the right direction so that they light up when it spins.
Step 7: Add a second battery for charging purposes.
I usually just let my generator run all night after I get home from work, exposing it to more kinetic energy than I could hope to produce on my own with a bicycle! Once your batteries are fully charged, you can unplug them and use them in your projects or dump the energy back into the grid.
It’s important to note that this device is not inherently safe so don’t leave it unattended for extended periods if you have pets or small children around! I’ve seen videos where people hook up their Tesla coils or other dangerous electronics to the same setup with no visible negative consequences but I am not responsible for any injuries or damages that may occur.
Step 8: Add some fuel.
People are experimenting with running these devices on all sorts of things including flywheels, wind turbines, hydroelectric dams, and even people in hamster wheels! The only limit is your own imagination (and the laws of physics).
Now that the generator is finished, you can use it to power all sorts of other machines. Just make sure your load matches up with the voltage output! If you’re not sure, check your component’s specifications or consult an expert before committing to anything dangerous like powering a car or blasting music at a dance party.
Building the Bicycle Generator
It’s all about finding free energy, either in your own bloodstream or environmental systems like wind and water currents. Once you get hooked up to something with enough excess energy to fuel your project, it should run indefinitely!
And with enough tinkering, you can create a perpetual supply of kinetic energy to power your life in your off-the-grid fortress!
One of the most significant inventions in human history, the Bicycle Generator is finally here.
All you need to do is pedal your bicycle for hours on end, and then add some boiling water! Presto! Your problems are solved. No more money wasted on dangerous fuels such as oil or coal; just cycling away and producing enough power to light up a small room for an evening.
How does it work?
The bicycle generator is such a simple device that works on the principle of heat. As you pedal your bike, the heat produced by friction is converted into electrical energy by a small generator device attached to your bicycle. This generator has a cooling system that absorbs all the heat produced during the process and hence converts it into electrical energy.
A bicycle generator is a simple device comprising of a ring, some magnets, and coiled wire placed inside the ring. As you pedal the bike, the magnets spin around on this wire, generating energy in the process. This electricity can then be used to run lights or electric fans etc. The higher your speed on the pedals, the more electricity is produced.
Building the Hydroelectric Generator
Step 1: Gather the materials.
You will need (in addition to your bike):- Two tees Two elbows Two plastic PVC tube caps with drilled holes at their ends 2 rubber washers A threaded pipe connector An electrical box A wooden stick
Step 2: Attach the rubber washers and PVC caps to the threaded pipe connector.
First, tighten the two rubber washers in a clockwise direction onto the threaded pipe connector (one each on both sides). Then add in another rubber washer and tighten it in an anticlockwise direction, but this time over the other rubber washer. Finally, add in the second rubber washer and tighten it in an anticlockwise direction over this one too.
Step 3: Attach the PVC caps to the tees.
This is probably the trickiest part of making your own hydroelectric generator because you’ll need to get the threaded pipe connector through both holes of each tee at the same time without breaking anything! The best way I’ve found is to hold up one side while inserting the connector through another so they match up perfectly beneath them (see picture).
After getting them lined up together, use your hands to twist on all four joint nuts until fully tightened.
Now that your pipes are securely attached, you can screw on each cap with ease! When you have them both on nice and tight, your generator is finished. Except for the final testing stage of course…
Step 4: Connect it to your bike!
Finally, all you need to do now is take out the small pipe connector at the top of your PVC caps, replace it with a bolt that fits in snugly but not too tightly (if you tighten it up too much it’ll make it hard for water to pour through). Finally, attach an electrical box (with switch) to this bolt, and then hook up some wire from the electrical box to your lights.
Your hydroelectric generator should now be ready to go! If any part feels flimsy or like it’s going to suddenly snap off, try wrapping some duct tape around it to give it a bit more stability.
A word of warning: Make sure you use some sort of waterproof fuse on the wire that comes from your electrical components – I recommend duct taping this one as well – because if water hits the switch and completes the circuit, you’ll fry all your electrical parts and there goes your whole day (or so I’ve heard).
Building the Hand Crank Generator
A hand-crank generator is a very simple device that converts your manual energy into electrical energy. The principle of working of this generator is based upon the dynamo principle. If you rotate a coil inside a constant magnetic field, an emf will be induced in it.
Similar to the bicycle generator, the handle of this generator also has three main parts:-
* Coiled wire
* Permanent magnets
* Platform to attach the device to the bike frame.
You simply need to attach this generator to your bicycle and start rotating the handle, you’ll see that it generates electricity that can be used for running lights, etc. Now just use your creativity and imagination, and think of a way to use the generated power.
Step 1: Gather the materials.
You will need:- A large iron nail Two U bolts, nuts and washers Iron pipe coupling, nut and a bolt Several permanent magnets A 4-5V DC motor or a dynamo (old fashioned bicycle generator) Some wire, or wire from an old electrical cord Electrical tape
Step 2: Make the coil.
Using a long iron nail, make a coil (you can use this to find the end of the nail by touching it with a screwdriver and running the current through it). Leave some space between each turn and make sure that there is no loose wire. It should look like this:
Step 3: Attach it to your bicycle and pedal!
Now attach one side of all your parts to your bicycle frame and start rotating the other part. If you have used a 4-5V DC motor then just connect in series all the wires from its leads, if you have used dynamo then just connect them in series. The light connected will glow brighter when you pedal faster.
If you are using a DC motor then all four brushes should touch the commutator uniformly. You can use bicycle lights or small lamps to know whether it is working properly or not. In dynamo the thing is, as you move your handle one way, an emf will be induced in its coil and this induces a current which charges the battery attached to it via diode D1.
When you turn your handle down, another diode allows the stored energy from the battery to flow back into the system and light up a bulb at that end of your generator set-up. With a little practice and experimentation, this type of lighting system can produce enough power to run both front and rear lights on a bicycle.
What are the Principals of Making Electricity?
There are two ways in which heat will create motion. This can be done by either expanding gas or compressing it. When the molecules of gas expand they push away from one another, but when they are compressed into one area this causes them to bounce off of each other creating kinetic energy.
Circulating this type of kinetic energy through wires creates electricity. Electricity is created by moving electrons around a circuit so that these electrons have enough of an electric charge to magnetize materials such as metal and attract light objects such as feathers or balloons.
A popular experiment demonstrating the principles behind how electricity works are called Ohm’s Law, although four laws make up Ohm’s Law. These include Voltage, Current, Resistance, and Power. Voltage is the measurement of the force that causes electricity to flow through a material.
The higher the voltage, the stronger it will flow. Current, or amps, is how many electrons are moving past a specific point in one second. Resistance is what causes heat within an object as electricity passes throughout it, so the less resistance between wires means less heat which makes better insulation for them.
Power is essentially voltage multiplied by current; this gives us an idea of how much electricity has been used over time.
Electronics can be created using these principles applied together with other knowledge to create devices such as televisions, games consoles, CD players, DVD players, etc… Without this knowledge-creating electronics would not be possible.
