DIY generator at 220 volts. Now blackouts are not scary

  • Tutorial
I will show how to assemble a simple but powerful enough 220 volt generator.

Would need:

- a collector motor, another one for 12 volts
- a nozzle on the motor axis - a chuck from a drill
- an UPS without interruption or an inverter from 12 to 220
- a 10 amp diode: D214, D242, D215, D232, KD203, etc.
- wires
- a bicycle
- and preferably a 12 volt battery


- we fix the bike so that the rear wheel spins freely, hang it out
- we fasten the cartridge to the motor axis
- we fasten the motor so that the cartridge snaps tightly to the wheel, you can tighten it with a spring
- we connect the motor to the battery: the negative motor wire to the battery minus, the positive motor wire to the anode of the diode, the cathode of the diode to the plus of the battery
- we connect the battery to the uninterruptible power supply or to the inverter
That's it! You can connect 220 volt consumers to the uninterruptible power supply and use electricity! As soon as the battery is exhausted, it will be enough to turn the pedals and after about an hour the battery will charge.

Where to get the details?

- the motor can be bought at a car store: a cooling fan motor. It is not expensive. And if you want almost nothing, then you can twist it at the metal reception point from an old car.
- an uninterruptible power supply from a personal PC, you can old with a worthless internal battery. Or inverter 12 - 220, sold in automobile stores.
- 10 amp diode, for example: D305, D214, D242, D243, D245, D215, D232,
D246, D203, D233, KD210, KD203, etc. Sold in radio parts stores. Or you can unscrew it from old technology.

My experience:

For several months I used this generator and it showed pretty good results! The charging current of the battery was about 10 amperes and depended on how to pedal. If you twist slowly, it turned out 5 amperes, if you twist as quickly as possible, then 20 amperes. The average power of the generator is 120 watts. Mostly used by consumers of low power:

- 3 W - charging the phone
- 5 W - radio receiver
- 7 W - charging and using the tablet
- 10 W - charging camera, flashlight and video camera
- 12 W - energy-saving light bulb
- 30 W - music center
- 40 W - laptop
- 70 W - TV (rarely included)

I had enough charge for almost a day, after which I pedaled for an hour and again I could use electricity.

If anyone knows other methods of generating electricity at home, share in the comments.
