This is my first blog. So sometimes I make mistakes. So sorry. I had an idea to make a low power bluetooth speaker. So I will share my concept with you. Follow these steps with me.

Step 1: How to Do It

This diagram shows how to connect all the parts. If you connect the batteries to this, the second diagram shows how to do it.

Step 2: Case

I found a discarded battery acid bottle for this case. Battery acid bottles often come with a motorcycle battery, so be careful if you use a battery acid bottle. But you can find another option. If you have a 3D printer, you can make your own case.The front black cover of the case is made of a non-used jadel ck 4 speaker.Try to get an idea of the case by using the images shown here.

Step 3: Assemble

As a last Step, add everything. When supplying power to the bluetooth speaker we designed, give about 5V.

Step 4: We Made It

We have finished creating our bluetooth speaker. Now enjoy it. Turn on the bluetooth on your smartphone and connect it to the speaker. Now have fun.
