Mp3 player power - on/off switch broke

So,I have this mp3 player that is very good for my needs, but its power switch broke off.When I opened the device, I realized that the switch was literally detached from it.This is a photo of the mp3.As the battery was almost detached aswell, I'll weld the it again, that is not a problem...But I'm not sure how I can fix the switch, it can be something improvised, I just need it to work...Any ideas?Thank you so much in advance!!P.S.: Sorry for any english mistakes, it is not my native language.P.S.2.: This is a very old device but a good one, as least for me.

12v 18650 battery with bms but no balance. Can we use 3.7v output from it for powering bluetooth module directly?

I am trying to make Boombox Speaker. The amplifier is 12v and the bluetooth module is 3-5v input. I have a single 12v BMS module, ofcourse with 4.2v, 8.4v, 12.6v dividers. Now suppose I power the amplifier with total output, it works fine. But can I take the output of one single divider i.e. 0-4.2v for the bluetooth module sepeartely and keep using the 12v for the amplifier?

How can you transmit audio using a Bluetooth Dongle?

Hey Everyone,I'm just a beginner with Arduino and what I'm trying to do is take an incoming audio signal and then transmitted through a Bluetooth dongle. I am using a USB Host shield that is connected to a Sennheiser BTD 800 USB Bluetooth Network Card. I've currently just been messing about with this SPP sketch from the USB Host shield library 2.0. What I'm wanting to do is to display the incoming audio signal in the plotter window. Pictures of the sketch are down below. If anyone has any ideas on how to program it to do this, it would be much appreciated.

How do I make a motion/touch-activated sound player?

Hey everyone,I'm looking at making a device that plays a single .mp3 file when it is moved/interacted with, i.e the device will be in a container of sorts, and when that container is hit or shaken, the sound file will play. Is this possible?I've tried looking on the website for similar projects but couldn't find anything as all the motion-sensor ones were to do with if something walks or moves in front of the device, whereas I want something where the motion is acted upon the device.Hope you can help me out!Thanks

Fairground ride Light setup

Hiya Everyone, I was wondering if i could have some help, I have recently purchased an old fairground ride light using cabochons and incandescent bulbs 240v @ 10W each and have wired it up in a 3 phase series circuit. Now the light works fine as a light however me being me id like to allow for each part of each letter to be controlled individually so i have split the signs into three areas purple, green and yellow and i would like to program something to control each part individually and allow for it to either flash or dim each part moving onto another transition, ive had a look around youtube and google but cant really find anything else like this. Please see attached photo of one of the letters

Wait for the response, which should be "OK+Set:2"The response never comesWhat am I doung wrong?Thanks for any hints,Jerry

I will only use motors sg90, jumpers, and arduino but I need the arduino code.So I want 4 things to move, you can see all of them in the video. I will then connect it to my computer and use my keyboard for movements. You are free to put any keys you want to control it. Please help asap. This project is for tomorrow for my school.
