## Introduction: ELECTRICITY BY WALKING

Hy everyone this is my first Instructable. In this Instructable i will show you how to produce electricity by walking :-)
using a very simple method .

## Step 1: Skills Required

1. Basic electronic
2. How to solder
3. How to use multimeter

## Step 2: Materials Required

• Piezo element (i recommend to buy this from online store because they are very cheap on online store)
( don't worry if you can get those elements .just buy buzzers as in the photo and remove its case and you can see the elements there)
• Copper wire
• Diode 1N4148
• Plywood or cardboard

TOOLS REQUIRED
• Plier
• Soldering iron

## Step 3: Removing the Plastic Case

Use a plier to open the plastic case
dont use any sharp pointed object to remove it
WARNING: while removing the case don't bent the piezo element

## Step 4: What Is a Piezoelectricity ?

Piezoelectricity, also called the piezoelectric effect, is the ability of certain materials to generate an AC (alternating current) voltage when subjected to mechanical stress or vibration, or to vibrate when subjected to an AC voltage, or both. The most common piezoelectric material is quartz. Certain ceramics, Rochelle salts, and various other solids also exhibit this effect.

## Step 5: Making the Base

I used a plywood for making the base. I used wood cutter for making a long piece of plywood
the long piece if used for raising the height of the platform for getting more pressure (This part is optional if you want you can skip it) stick all the long piece as shown in photos
Now cut out carboard a little bit larger than the element and leave a "U" at the pace of soldering .The carboard is used to prevent damage to the element and the "U" gap is to prevent damage to the soldring on the element and to to make the element stick on the board properly

## Step 6: Connecting the Diode

Join the two wires coming from the crystal together and connect it to the anode(+) of the diode and the cathode(-) to the main wire (red). Repeat this step for all the elements
Use a tape to hold the wires to board or else it make lots of confusions later

## Step 7: Making the Top Layer

Keep a plastic thermocol sheet over the board to prevent damage to the elements while walking over it
Cover all elements with a plywood as the size of the base

Connect a multimeter at the end of two main wires and walk over it

## Step 9: Troubleshootings

• Recheck whether all the diode are connected properly
• Check all the crystals
• Check whether anywhere the two main wires are coming in contact with each othe
• The board which you are using as base should not contain any moisture

## Questions

how much current this generate?? i am confused , it is producing high voltage but no current

how many amp does this setup produce? I can see it make about 15 volt, and would to know the amp it can push to make certain application.

In which store can we buy this

hi i just want to ask your approval if i can use this as my project??

yes
but how??

hi i just want to ask your approval if i can use this as my project??

Without using a full wave diode bridge rectifier arent you loosing 1/2 of the voltage/current?

How much voltage would it generate?
You could attach it within your shoes. Generate some volts while losing some calories.

It generate upto 14-18v

So if I could stuff it within my shoes, it could power my smart phone.
Connect it with a rechargeable battery, it could charge my phone.

This is awesome. I've always thought of making a piezo electric floor. Nicely done. You can also get bulk packs of piezo elements online, might be cheaper than a bunch of buzzers. Or musical greeting cards sometimes have them too.
