Cellphone Charger Circuit Using Pendulum Generator

Last Updated on August 2, 2019 by Swagatam 20 Comments

This pendulum electricity generator can be used in villages for charging cellphones free of cost just by applying momentary pushes to the pendulum frequently or as desired throughout the day.

Pendulum as Free Electricity Generator

In one of my previous articles I explained about the high efficiency value of a pendulum mechanism, and how it could be used for generating almost free electricity using a minimal input effort, in this article we'll learn how the same principle can be executed for charging cellphones free of cost.The following figure shows the basic set up which can be applied for charging cellphones free of cost.

caution electricity can be dangerous

Referring to the figure above, we can see a relatively simple set up consisting of a DC motor rated at 12V, 5amp (or any other specs depending upon the output requirement), a bridge rectifier, a few super capacitors and a 7805 IC voltage regulator.

Circuit Operation

The motor spindle is appropriately configured with a mechanical pendulum assembly consisting of a pulley and a shaft, the shaft has a heavy spherical mass attached with its lower end.

The whole system is appropriately clamped over a firm base using brackets and angles (not shown in the image)

The functioning of the proposed free pendulum cellphone charger is rather simple.

The spherical mass is kept oscillating by applying frequent flicks manually, which is repeated only while the pendulum system is about to come to a halt.

Being extremely efficient by its nature of functioning, the pendulum can be expected to oscillate for quite sometime with every push, generating precious electricity for the connected cellphones, charging them almost free of cost.

The super capacitors are added for ensuring maximum outcome, however any ordinary high value capacitor may also be used with effective results, such a a few 2200uF/25V would be just enough.

In order to achieve maximum efficiency and higher sustain rate of the mass, two things needs to be taken care of: 1) the weight of the attached mass and 2) the length of the pendulum shaft, both of these are directly proportional to the efficiency of the system.

Meaning if the mass is more heavy and/or the shaft is lengthier would result in greater efficiency from the system, ensuring lesser manual effort for keeping the oscillations sustained for longer periods.

Using IC 7805 Regulator

The IC7805 is a linear voltage regulator IC which implies that it would dissipate heat significantly during the charging procedure which in turn might result in a reduced efficiency.

In order to overcome this, one may consider employing a buck converter circuit at the output instead of the shown 7805 IC, as shown in the following image
