## Introduction: Make Energy by Moving Your Hands in Your Free Time

Hello all,

This is my very first instructable! I have made a machine using a motor, some electronic components, gears and pulleys to very efficiently convert the kinetic energy from a persons hands into electricity. This can produce, at fastest speed, up to 12 volts, but it is controlled at 5 volts because I made it to only charge mobile devices. It has unlimited potential as more gears are added, and a bigger motor is used. It can also be connected to a bicycle or car wheel to produce amazingly high amounts of electricity. About 10 - 15 minutes of spinning would get your smart phone or tablet charged up to 40% - 50% if the product is built correctly. Good luck, and enjoy.

## Step 1: Planning and Building

Sorry for the inconvenient format. All instructions are written in images. All the instructions are very clear and easy to follow.

Here is a video showing how it worked out at the end.

## Questions

It would be nice to upgrade and install thіs invention on a bicycle or something like that. It would be cool!

5volts 100 watts means 5v at " 20 AMPS " did you wish to fry up your phone. Or does it mean 100 mA ?

A few details:

Most chargers are about 5 watts, where does 100 watts come from ( and note, current is amperes not watts, watts are units of power )? A good athlete is good for only about 250 watts, for modest periods of time.

It looks like only the cell phone battery stabalizes the voltage, is this correct?

What a fun cool concept! Definitely interesting in this greener world!
