Description

The world is advancing today, with new technologies that come up; it is no more the ancient world of manual work. Its time where robots and complex technologies do things we have always dreamt of. The roots of this technology are embedded deep within their circuits. Every technological device is perfectly woven in threads of wires and complex circuits. With all the wires and complex structures, it is challenging to make a circuit if you wish to innovate a new device. But what if you can just draw it out! You do not need a highly sophisticated pen to do it; just take a pencil and a paper to draw out your circuit. And we’ll tell you how to make it work! The CircuiTricks Book of Awesomeness is about creating electronic circuits with paper! This book will teach you how you can make your own electrical circuits by using just a paper and a pencil. All you have to do is draw the circuit! This will include creative things like making a music system using, making disco lights, creating your own motor plane and creating your own games using a paper and a pencil! This might be the most mind sparking creative maker book you would have ever read!

What’s this?
Today, electronic circuits are build using circuit boards, thin copper
stickers or thick copper wires. But what if you can build a circuit
using just your pencil and paper?
Papertronics is one such initiative where we encourage everyone to
build something innovative. No matter how complex an item looks,
we believe that it should be simple inside.
With Papertronics we introduce one such innovative idea which is
born from simple high school physics. In this idea, we will be able to
light up an LED, create some awesome music, create an-auto
controlled toy plane, design extra-ordinary games, etc. All of this
using pencil and paper!






Papertronics was exclusively presented at MIT’s FabLab Fab10
festival in Barcelona, Spain held on 2nd July to 8th July 2014 by
Nirman Dave and Sohil Patel, members of FabLab CEPT, India.

Well, when we use a pencil to draw out lines, we are actually
drawing wires! So, we are drawing out copper wires with pencil and
not having them physically.
This is because, the pencil contains graphite. Graphite is made
almost entirely of carbon atoms. It has a hexagonal structure, and
carbon atoms form double bonds with other carbon atoms. The
Lewis structure of these bonds manifest to the fact that there are
free electrons present in the carbon-carbon bond. These free
electrons illustrate graphite’s property of high electrical
conductivity and low resistance.

With this property of graphite, we can allow the passage of
electricity through paper by drawing lines of graphite with pencils.
These dark, shaded lines will act as circuit wires, hence allowing you
to create complex circuits just by drawing lines on paper!
Using this booklet
This booklet designed to make you feel more comfortable and easy while
experimenting. Here is what journey will look like.
Consisting of two columns, the left column will give you instructions and
the right will show tutorials for T1 to T4 levels. As you reach level 4,
tutorials will be gone, and you will face real challenges. I won’t say much,
have a look.

Level #T1
S i m p l e L E D t e s t
In this tutorial, all you have to do is trace the path given on the
right with pencil. Make it dark. Then attach the crocodile clips
connected to a 9V battery on one end and a LED on the other end.
Make sure you don’t mess up the positive and negative terminals!
Try checking what happens when the distance between the LED
and battery decreases. By moving the LED in different positions.
Then note down your observations below.

Level #T2
V a r i a b l e r e s i s t o r
In this tutorial you will have to create a variable resistor. Don’t
worry, all you have to do is pick up your pencil and fill up the block
in the left.
Then attach the positive terminal of the crocodile clips connected
to a 9V battery on one end of the block, name it origin. And the
negative terminal to the positive terminal of the LED. And let the
negative terminal of the LED be free.

Then pin the negative terminal of the LED on one end of the block
and vary its distance from the origin. This will affect the brightness
of the bulb, hence creating a variable resistor, with just pencil and
paper!

Level #T3
D i s c o li g h t s
This tutorial will teach you how to make your own disco lights. All
you have to do is add small lines/dots to the circuit shown in level
3. And then pass the LED over those lines.

The concept remains simple, when the negative terminal of the LED
comes in contact with the graphite line. It glows up, however, when
not in contact it does not glow. When this LED is slides through the
graphite lines, a continuous pattern of on and off is shown. And
your disco light has been made! Use the template on the right to
create your own LED disco light.

Level #T4
M a k i n g m u s i c w i t h p e n c i l a n d p a p e r
The design remains the same as it was in level 3. All you have to do
is attach a buzzer instead of the LED. Hence the buzzer will buzz
each time it passes over a graphite line. Later rearrange the
graphite lines to buzz the buzzer at given points. Hence creating
music.

Level #C1
L o s t i n t h e m a z e
Until now you have only encountered T levels, which were simple
tutorials with templates. This is the first C level, this level
introduces new challenges and allows your creativity to fly.
This level is all about creating your own maze game. Using the same
concept, draw simple pencil lines and pass the LED pin through it
solving the puzzle. Make sure it doesn’t touch the graphite line. If it
does, the LED glows up and you are dead!
Your challenge is to use the workspace on the right to create your
own maze game. The circuit is similar to the ones displayed in
tutorials, however have a look at the picture below for reference.

Level #C2
B u z z i n g d r u m s
Well, besides making music from buzzers u can make drums too! All
you have to do is make different connecting circles and shade them
with pencil. Every circle has a different shade, leading to different
electrical conductivity and hence different sounds!
Your challenge is to create your own drums using the workspace
area on the right. The circuit is similar to the ones displayed in
tutorials, however have a look at the picture below for reference.

Level #C3
A u t o m a t e d p a p e r p l a n e
We all know how to make paper planes. But how about u attach a
motor behind the plane, using pencil cells and graphite lines
instead of wires!
A motor is attached at the end of the plane. The motor is connect
to a pencil cell using a graphite line. When a u-pin is added beneath
the paper plane the lines touch the pencil cell, completing the
circuit and hence powering the motor. Allowing plane to fly! [You
will need a micro helicopter motor only]
With such an embedded circuit in the paper plane, your plane will
be able to fly more efficiently and smoothly. Bur keep in mind, your
challenge is to create such am embedded circuit using a motor,
pencil cells, pencil and paper.
Here is a supporting diagram to give you a brief idea.

Endless possibilities
The book may end here but Papertronics has endless possibilities.
Use your creativity and try making something new! Hope you
enjoyed the idea.
Best of luck & keep it creative!
