Golden Shovel Showdown - Bluetooth Speaker

The "Golden Shovel - Powerful Voice Showdown"
Bluetooth speaker
 
is now complete!
 
First, admire my newly acquired "Golden Plate "—it
 
's so beautiful QAQ! There are four buttons: power on/off, previous track/volume down, next track/volume up, and pause/play.
Volume up/down can be adjusted by long-pressing the buttons or using the volume knob.
 
Two speaker versions were made, one large and one small.
 
 
The large speaker is the most common 4 ohms 3 watt type, while the small speaker looks like this; it's quite compact .
 
 
The audio cable is soldered close to the board for a cleaner look.
 
 
The Type-C charging port and power switch are on the back.
 
 
Left side view ,
 
right side view
 
, internal view—super spacious, you can put all sorts of things here.
 
Bottom view (I only realized after getting ten Hearts of Steel that the hardest bond to get is you and me QAQ).
 
With Steel, play Steel; without Steel, just keep playing. Open 3 Steel, search for 5 Steel, get 7 Steel, gamble on 10 Steel, and Steel
is all you need. This game is over, next game is 8, enjoy every game you can. This season there's only one bond: Hearts of Steel. Once you enter the Steel gate, there's no turning back; the Steel gate will last forever!!!
 
Let's see who hasn't gotten addicted to steel! If there's steel, then steel; if there's no steel, then steel is a must. No kids crying every day, no gamblers losing every day!
 
Okay, okay, that's enough rambling. Remember to like my video, thanks for the triple tap!
