We offer you a review on the manufacture of a portable budget tape recorder that can be used during trips.
We offer you to familiarize yourself with the author’s video
So we need:
- special fee;
- microSD memory card;
- rechargeable battery;
- speaker power up to 3 watts;
- a plastic container as a case;
- marker.
The first step is to transfer the round shape of the speaker to the lid of the container.
Next, we drill a small diameter drill along the contour of the round line of the speaker ring. We take a breadboard knife and cut out the resulting circle without any problems.
Now you need to screw the speaker on the lid of the tank with four bolts.
The blue connector needs to be unsoldered, since it will interfere with the unhindered installation of the board in the tank.
We put the board with the upper part to the side wall of the tank and mark the cutouts for the USB connector, as well as the memory card slot and buttons.
As buttons, you can use the heads of conventional LED bulbs. They just need to be broken off and glued to the buttons on the board.
Let's move on to soldering all the components. The minus from the battery box should go to the contact on the switch, and from it to the board. Plus, from the board we spend immediately on the battery box.
Our portable player is ready. It remains to insert the battery into the box, insert the memory card with your favorite music and enjoy the result of the work done. Note that in the absence of a battery, the board can be powered with a regular Micro USB charger.
