arduino speaker


I want to buy both Amazon, Alexa and Google home, but they are quite expensive to both 250 dollars aprox. But in my wallet I have only 30, so I was wondering if it is possible to build both Alexa and Google together. In a single smart speaker, even under 30, I chose wood for speaker cabinet. So first I went to a wood mill and bought a scrap. Wood bundle less than a dollar. It looks good to me, but after returning home, when I cut the bundle, then I saw most of the woods are defective and they are different in color. So I went back to them and bought a quality woods just adding two more dollars and this woods are really good.. I generally do not work with wood that’s, why I have very less number of woodworking tools, so I went to my nearest tool market and after some bargain, I bought few carpentry tools at very low price. I bought a handsaw hole, making saw wood glue and some different grits and papers next day. I woke up early in the morning and first I marked the woods to 8 inches and cut it using handsaw. Then I roughed out those pieces using 60 grit sandpaper and after some action I used 120 grit sandpaper and the wood pieces became this to this.. Then I took some measurements and drew the outlines. Next, I cut the side. Excess areas using hand saw and made it round after that I drilled few holes and started cutting according to the measurements.

It’S a tedious process and the outcome is not perfect, but it got the job done and that can be fixed after some sanding. Then I went to the speaker market and bought two speakers that costs me around 1 and 20 cents. Next, according to the speaker size I drilled two holes and after some sanding hole, walls became smoother now cutting is finished. Next, I join those pieces using wood glue. After a while, I gathered some wood dust and mixed it with some glue and filled those gaps next day. I have sanded the excess area and made it smooth to make a LED notification ring at the front. First, I make a silicon mold then mix some epoxy resin and pour it on to the mold when it hardened, then I joined it with main body and after applying some polish, the enclosure has completed so it’s time for the electronics To cut the price I’m. Using a 10 single board, computer Raspberry, Pi, Zero, W and here comes the most challenging part because it does not have any audio in our audio out port. So I cannot directly use microphone and speaker on it to sort out this limitation. I have done a lot of research and testing that literally took me more than a month and finally, I have designed a circuit that connect with raspberry PI’s USB port and provide audio in and out functionality. Also, I have added power bank and audio amplification functionality into the circuit.

Then I converted the circuit into PCB and order it from PCBWay. They generally charge 5 for the PCB, But if we are ordering for the first time, then our PCB will be absolutely free of cost. So here I said 5 Few days later I got my PCB. The PCB quality was excellent and the color was very satisfying next. I opened mycomponent diary and collect all the required components which costs me no more than eleven dollars. Then I started soldering. If you are interested to see how to solder SMD components then leave a comment. I will make a dedicated video on SMD soldering after soldering all components. I attached the microphone, two speakers notification LED Battery and finally, the Raspberry pi Now circuit has finished So next I installed raspbian OS in raspberry pi to insert Alexa into the system. First, we have to create an account in Amazon developer page. Then we will get a client ID after that Amazon redirects us to some steps which we need to follow to install Alexa into raspberry pi after installation. We can see the status of Alexa as currently idle, which means Alexa is working. Now we need to install google assistant as well by going to the Google developer page and create a new project to enable the assistant API and do the necessary steps provided by the site, the link of all the steps which you will need. You can find in the description box below Now that the system is ready.

We have to assemble the required items inside the cabinet that we prepared, while doing this one by one. Let us talk about Squarespace today’s video, sponsor Squarespace is an all in one platform for creating your own domain website on an online store. They have beautiful templates and a lot of customization tools, and it is helpful for those who don’t know how to code and still want a beautiful looking website for their company side, business or anything of that sort. If you still need any help, you can contact their award winning 247 customer help line service. When you will make your order, don’t forget to use coupon code DDELECTROTECH for additional 10 discount. Finally, the assembly is ready. I really love the look of the speaker, especially the light ring. How do you find it? Let me know in the comment section now it’s time to test it and compare it with the original Amazon echo and Google home Alexa. What is the time it’s 0444 p.m. hey, Google? How are you I’m? Well thanks? How can I help you alsocontrol your home appliances like Alexa switch on the light? Ok make the light red. Ok, The sound quality is also very good, with a very good bass play. I need only you, I need only you buy love beans starting now. The major difference between my speaker and Alexa or Google home is that my speaker has built in battery, so I can take it anywhere, but Google, home and Amazon echo does not have any battery.

They always need a power supply so it’s time for the giveaway and declare previous winner name. Congratulations to Abhishek Shah for winning the tablet of the previous giveaway. We will be contacting you Today. We are going to give three Amazon echo dot to three lucky subscribers. All you need to do is comment down below and share this video, so that’s it for now see you in our next video.
