With the help of this small pocket generator, you can immediately charge not one but several cell phones, light an LED lamp, and other applications that may not have occurred to me are possible. It produces a pure sinusoidal voltage of the order of 120-230 V (depending on the rotation speed) and gives out power in the region of 3-5 W with a frequency of 50 Hz, which is important. In fact, this is a micro power station in your pocket. Take it on a hike and you will have a 100% source that will never be discharged.
Microwave drip tray drive. If not, then buy on Aliexpress (link)
He twists the plate and works on line voltage. It looks like a flat electric motor with a shaft shifted from the center - this is due to the gearbox built into it. The whole feature of it is that it also works in the opposite direction: it generates an electric current during rotation.
For the case we will use a plastic jar of cream.
How to make a 220V manual generator
In the lid we drill a hole under the motor shaft.
We are trying to install it there, but so far we are not fixing it.
You need to find a handle from the amplifier, it will fit well on the shaft, as the shape of the recesses is very similar.
We try to rotate the shaft, if everything goes easy, then the handle sits normally.
A resistor with a resistance of 100-200 kOhm is successively soldered to the LED. We put on a heat shrink and blow a hairdryer.
Let's make a hole for the LED in the lid. It will show the presence of work and the return of tension.
Solder the contacts to the generator.
As an outlet, we take an adapter plug.
Let's make holes for her contacts with a soldering iron.
Connect to the contacts and insulate them.
Set in place.
Solder the output to the generator.
We make assembly. We put all the elements on epoxy glue so that everything is held securely. Close the case.
To make it easier to rotate the dynamo, we will make a handle. To do this, cut a long strip of metal.
Make a hole for the handle.
The cap from the ballpoint pen will play the role of a hinge.
Saw off the edge.
Putting the pen together.
Glue it on epoxy glue.
Check the operation - the LED is on.
We perform a check on a real load. In her role will be a 220V bulb.
We connect, it burns well.
Now try to charge the phone.
The charge is on. And now all together.
Power is enough!
Thanks to the gearbox integrated in the motor, it is not necessary to rotate the shaft at high speed. Calm rotation with a measured frequency will not heavily load your hands, from which you can nourish your loads for a long time.
