DIY-Home Made Incubator Eggs Hatcher -How to make an AC- DC incubator :

<h1 style="text-align: left;"><b style="mso-bidi-font-weight: normal;"><span style="font-size: 12pt; line-height: 115%;">Introduction:</span></b></h1><div style="text-align: left;"><span style="mso-bidi-font-weight: normal;"><span style="font-size: 12pt;">                        An incubator is a machine which
is use for hatching bird’s eggs. The incubator we design can almost hatch all
kinds of bird eggs. Like Chickens, Ducks, Pheasants, Peafowls, Turkeys etc.</span></span></div>

<p class="MsoNormal"><span style="font-size: 12pt; line-height: 115%;">       The
Incubator we design here is Semi Auto. It means that The temperature
control<span style="mso-spacerun: yes;">   </span>will be automatic while eggs
turning will be manual by hand also humidity will be manual .it’s very easy to
operate a semi auto incubator successfully .For humidity level control you just
need to increase the water surface level will increase humidity level and vice
versa . <o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size: 12pt; line-height: 115%;">The eggs
turning .Two to three times a day will give you a good result. (For good result
8 hours duration between each turning)<o:p></o:p></span></p><div class="separator" style="clear: both; text-align: center;"><span style="font-size: 12pt; line-height: 115%;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhTuervfWMANGjs6aoDwEmuAreGb3q36rKS7hHJthuiZqtpUy7qnmp8mmuY762NX6njbb53PwQiGB-0H5NmegegytMls4nhwpbwTWiu0-ihPkTgqgyTn48uQY3DEHLg58Mk4OPDMHQ_eJ19/s2048/20200611_221537.jpg" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="1152" data-original-width="2048" height="180" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhTuervfWMANGjs6aoDwEmuAreGb3q36rKS7hHJthuiZqtpUy7qnmp8mmuY762NX6njbb53PwQiGB-0H5NmegegytMls4nhwpbwTWiu0-ihPkTgqgyTn48uQY3DEHLg58Mk4OPDMHQ_eJ19/w320-h180/20200611_221537.jpg" width="320" /></a></span></div><p></p>

<p class="MsoNormal"><b style="mso-bidi-font-weight: normal;"><span style="font-size: 12pt; line-height: 115%;">Components Used in This Project:<o:p></o:p></span></b></p>

<p class="MsoNormal"><span style="font-size: 12pt; line-height: 115%;">1: A Box (Can
be made from Wood, fly board, plastic or Aluminum anything that can hold heat
inside).<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size: 12pt; line-height: 115%;">2: Temperature
Controller I am using two W1209.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size: 12pt; line-height: 115%;">3: A
Hygrometer which shows you Humidity level. I am using<span style="mso-spacerun: yes;">      </span>……..<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size: 12pt; line-height: 115%;">4: Eggs Tray
which holds eggs inside Incubator box and also helps in turning eggs with hand.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size: 12pt; line-height: 115%;">5: A Bowl
for water to maintain the required humidity level.<o:p></o:p></span></p>

<p class="MsoNormal"><b style="mso-bidi-font-weight: normal;"><span style="font-size: 12pt; line-height: 115%;">Construction:<o:p></o:p></span></b></p>

<p class="MsoNormal"><span style="font-size: 12pt; line-height: 115%;">First of all
you need to make a rectangular box. You can make it from wood, fly board,
plastic or aluminum anything that you have access and have a property of
holding heat. Look at the picture and you will be get an idea I am using simple
fly board .you can make it with your own hand or make it with your local
carpenter. <o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size: 12pt; line-height: 115%;">All the
measurements are given in the block diagram you can change the measurement according
to your needs.<o:p></o:p></span></p>

<h3 style="text-align: left;"><b style="mso-bidi-font-weight: normal;"><span style="font-size: 12pt; line-height: 115%;">Understand before Power connection:</span></b></h3>

<p class="MsoNormal"><span style="font-size: 12pt; line-height: 115%;">If you have
no power failure problems and load shedding then it is good for you make only
AC connections in your incubator.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size: 12pt; line-height: 115%;">If you have power
failure issues and load shedding problems then go for both AC and DC
connections in your incubator:<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size: 12pt; line-height: 115%;">Both AC and
DC operate in same incubator box. In normal condition AC system operates when
the AC system go off them DC system work as backup because your incubator need
power 24 Hours a day along the full incubation period.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size: 12pt; line-height: 115%;">With two
ways you can operate both systems successfully.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size: 12pt; line-height: 115%;">1: Installed
any AC or DC relay in DC system.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size: 12pt; line-height: 115%;">2: Set your
DC temperature controller On time 1 degree lower from AC controller.(for
example your AC controller relay ON at 37.3 C<span style="mso-spacerun: yes;"> 
</span>your DC controller relay need to turning ON at 37.2C..<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size: 12pt; line-height: 115%;">The better
way is to install an extra relay. The second method is just a solution of your
problem in case you don’t have a relay.<o:p></o:p></span></p>

<h3 style="text-align: left;"><b style="mso-bidi-font-weight: normal;"><span style="font-size: 12pt; line-height: 115%;">AC power connection:</span></b></h3>

algorithm for implementing Fourier transform. Basically, it is a method of
implementing the algorithm .these are for implementaion.we use fast Fourier
transform because it is an efficient algorithm</span></i></p>

Fourier transform will give us frequencies overall in this sound signal. This
Fourier transform gives us overall frequencies contained in this speech signal.In
speech recognition not all of these frequencies are helpful because it is not
our aim to find out how much frequencies are contained in this speech
signal</span></i></p>

frequencies. Fourier transform provides us combined frequencies of all the
sound with no time information. what frequency at what time.</span></i></p>

Fourier transform of the whole sound signal.we just pick a signal of 10msec
duration from the above sound signal.</span></p>

information. But the disadvantages is that when we take this sharp 10ms then signal
edges which are called leakage or cut signal.</span></p>

called wrong frequencies.sharp edges are due to wrong frequencies.</span></p>

edges or discontinuities at the input signal and at the end Windowing is
performed</span></p>

</span>rather than 10ms. we will take 25ms duration and take the Fourier transform
of these signals.And then associate these frequencies in the middle. that is found from the Fourier transform.<i></i></span></p>

frame duration. The basic purpose of windowing is to smooth the sharp edges in the 25ms. Due to the high duration, these sharp edges become smooth.</span></i></p>

increase much more then double then the other characteristics will also count
in it. Usually, take double the windowing then the frame duration.</span></i></p>

proportion.so what we do to it change it to linear. We convert the Hz scale into
mel scale. So what is mel scale conversion? In it, we just map that frequencies
