I want to buy both Amazon Alexa and Google home
[9]
but they are quite expensive to
both 250 dollars aprox
[14]
but in my wallet I have only $30
[15]
so I was wondering if it is possible to build
[19]
both Alexa and Google together in a
single smart speaker
[25]
even under $30
[29]
I chose wood for speaker cabinet
[32]
so
first I went to a wood mill
[36]
and bought a scrap wood bundle less than a dollar, it
looks good to me
[40]
but after returning home when I cut the
bundle then I saw most of the woods are
[45]
defective and they are different in
color
[49]
so I went back to them and bought
[51]
a quality woods just adding two more
dollars and this woods are really good.
[59]
I generally do not work with wood that's
why I have very less number of
[63]
woodworking tools so I went to my
nearest tool market
[87]
and after some bargain
[89]
I bought few carpentry tools at very low price
[92]
I bought a handsaw hole-making saw
[95]
wood glue and some different grits and papers
[101]
next day I woke up early in the morning
[104]
and first I marked the woods to 8 inches
[111]
and cut it using handsaw
[116]
then I roughed
out those pieces using 60 grit sandpaper
[122]
and after some action
[123]
I used 120 grit
sandpaper and the wood pieces became this to this.
[130]
then I took some
measurements and drew the outlines
[134]
next I cut the side excess areas
[137]
using hand saw and made it round
[139]
after that I drilled few holes
[146]
and started cutting according to the measurements
[150]
it's a tedious process
[156]
and the outcome is not perfect but it got
the job done
[159]
and that can be fixed after some sanding
[163]
then I went to the speaker market
[166]
and bought two speakers
[167]
that costs me around $1 and 20 cents
[172]
next according to the speaker size
[175]
I drilled two holes
[182]
and after some sanding hole walls became smoother
[189]
now cutting is finished
[191]
next I join those pieces using wood glue
[202]
after a while I gathered some wood dust
[206]
and mixed it with some glue
[213]
and filled those gaps
[218]
next day I have sanded the excess area
[222]
and made it smooth
[228]
to make a LED notification ring at the front
[231]
first I make a silicon mold
[234]
then mix some epoxy resin
[248]
and pour it on to the mold
[257]
when it hardened then I joined it with
main body
[267]
and after applying some polish
[270]
the enclosure has completed
[275]
so it's time for the electronics
[277]
To cut the price I'm
using a $10 single board computer
[281]
Raspberry Pi Zero W
[283]
and here comes the most
challenging part
[287]
because it does not have any audio in our audio out port
[290]
so I can not directly use microphone and speaker on it
[294]
to sort out this limitation
I have done a lot of research
[297]
and testing that literally took me more than a month
[302]
and finally I have designed a circuit
[304]
that connect with raspberry PI's
USB port
[307]
and provide audio in and out functionality
[310]
also I have added power bank and
[312]
audio amplification functionality into the circuit
[315]
then I converted the circuit into PCB
[322]
and order it from PCBWay
[324]
They generally charge $5
for the PCB
[327]
But if we are ordering for the first time
[329]
then our PCB will be absolutely free of cost
[333]
so here I said $5
[335]
Few days later I got my PCB
[338]
The PCB
quality was excellent
[340]
and the color was very satisfying
[342]
next I opened mycomponent diary
[344]
and collect all the required components
[349]
which costs me
[350]
no more than eleven dollars
[354]
then I started soldering
[362]
if you are interested to see how to solder
[364]
SMD components then leave a comment
[366]
I will make a dedicated video on
SMD soldering
[378]
after soldering all components
[381]
I attached the microphone
[384]
two speakers
[386]
notification LED
[387]
Battery
[389]
and finally the Raspberry pi
[392]
Now circuit has finished
[394]
So next I installed raspbian OS
[396]
in raspberry pi
[398]
to insert Alexa into the system
[400]
first we have to create an account in
[403]
Amazon developer page
[408]
then we will get a client ID
[410]
after that Amazon redirects us to some steps
[414]
which we need to follow to install
[415]
Alexa into
raspberry pi
[418]
after installation we can see
[420]
the status of Alexa as currently
idle which means Alexa is working
[425]
Now we need to install google assistant as well
[428]
by going to the Google developer page
[430]
and create a new project to enable the
assistant API
[433]
and do the necessary steps
[436]
provided by the site the link of all
[437]
the steps which you will need you can find
[440]
in the description box below
[443]
Now that the system is ready we have to assemble
[446]
the required items inside the cabinet
[448]
that we prepared
[450]
while doing this one by one
[452]
let us talk about Squarespace
[454]
today's video sponsor

[488]
Finally the assembly is ready
[491]
I really love the look of the speaker especially
[494]
the light ring how do you find it
[496]
let me know in the comment section
[499]
now it's time to test it and compare it
[501]
with the original Amazon echo and Google home
[504]
Alexa what is the time
[508]
it's 04:44 p.m.
[510]
hey Google how are you
[513]
I'm well thanks how can I help
[515]
you alsocontrol your home appliances like
[519]
Alexa
[520]
switch on the light
[523]
ok
[525]
make the light red
[528]
ok
[530]
The sound quality is also very good
[533]
with a very good bass
[535]
play I need only you
[537]
I need only you buy love beans starting now
[577]
the major difference between my speaker
[579]
and Alexa or Google home is that
[582]
my speaker has built-in battery
[584]
so I can take it anywhere
[586]
but Google home and
[587]
Amazon echo does not have any battery
[589]
they always need a power supply
[592]
so it's time for the giveaway
[594]
and declare previous winner name congratulations to
