I was a bit bored in the workshop without music. The old music center I had there took up too much space and I had to get rid of it. At first I thought of connecting a cheap Chinese bluetooth stereo, but a friend asked me to buy it for his boat.
From one client I had a bluetooth module, which was designed to be installed in a music center, but it did not fit as the client wanted to connect two more powerful speakers to the center. Another one was ordered, the amplifier was purchased, and this one went to my box. I'll leave the link to the module below, the store is trusted, I've ordered ten units there and everything is fine.
In general, I searched in my zagashniki and found something that can be used to make this device.
Bluetooth module: http://alii.pub/6e1t2q (in my case it's the 3.7-5V version).
Power socket: http://alii.pub/6e1tfr
Fuse socket: http://alii.pub/6e2ugh
Fan 40*40*10 2PIN: http://alii.pub/6e2uje
12v 3A power supply: http://alii.pub/6e2umi
Switch: http://alii.pub/6e2uou
Clock: http://alii.pub/6e2uq7
LM2596s step-down power supply module: http://alii.pub/6e2usj
Acoustic terminal: http://alii.pub/6e2uua
10A fuse
M3 solder bushings (length 4mm OD 4.2mm) 8 pieces: http://alii.pub/6e2v6c
Fastening
Screw M3*10mm - 12 pcs.
Screw M3*12mm - 8 pcs.
The body was printed with PLA plastic from Eryone, I bought it to try, it was pretty good http://alii.pub/6e2vdq.
As for the case
The enclosure was not made too small, and despite its small size, there is still plenty of room to install additional modules, such as an amplifier, if necessary. The LM2596s step-down module mounting bed is designed as a separate part. It can be glued in any convenient place, if it is needed at all. In my case, I had to put it in because the bluetooth module itself is powered by 5 volts, the other consumers are powered by 12 volts.
The fan grille on my printed model is not very convenient, so I replaced it. A wide variety of grille models can be viewed and downloaded at this link: https://www.thingiverse.com/thing:1879694/files.
The handles that are mounted on top are decorative in nature, they may not be installed, but simply screwed into their seats, thereby further securing the front and back panels.
The glass under the clock I cut out of ordinary synthetic plastic 2mm thick, and covered it with tinting film. Attached to the project is also a model of the glass template, which is convenient to cut it from.
I also designed and added to the project a small stand for the bluetooth module remote, there are also two sockets for USB flash drives and two Micro SD flash drives.
I didn't make a wiring diagram, nothing complicated there. I think everyone will figure it out.
Anyway, we got what we got!!!! We made it from what we had!!!
Support me in my new projects!!!
