soldered the boards and added buttons
for the first attempt i did it solder free as i didn't have the tools yet so now i as i have them i disconnected everything and soldered it again now it's more durable and i added buttons (the board alr got the buttons but i soldered extra wires to connect them to other buttons on the box cover
1- soldered
2- buttons
3- working
4- cutting pos instead of neg this time (switch)
#what i used

#connections

and then i used my secret power to assemble it (MAGIC) yah that's right i used magic
i'm joking i just used the power of hope,love,back bending
to turn it from this

to this

Hi, please add more depth to your journal with every step you took along the way to create the project as right now for 1 journal you have 12 hours listed whereas a good maxium amount to aim for is 3 hours max per journal entry.

the whole thing (mp3 player journy)
had different approaches with different goals the first ever approach included a boost converter step-up module to make a secondary mode using speakers had the prototype and everything but it just lost the main goal of being portable and the long playtime so cancelled that and switched to aux headphones approach using a charging module tp4056,mp3 decoder GPD2856 and 18065 battery 1500 mAh with battery holder (to avoid soldering) and adding a switch to change modes 5v (charger) or battery mode
the first problem
1-size if i used speakers -------> switched to smaller design and used aux instead as it more convenient to me
2-when i added the switch for the first time i used an DPDT slide switch 6-pins to cut both live and gnd but it didn't work for no reason and then tried cutting only live and still didn't work
fix ------> i changed the switch with a red button and cut gnd instead of live and it worked
3-fitting the project in box the wires weren't that flexible and couldn't fit it in
fix ------> i rewired everything and measured the dimensions of the box to make wires shorter
4-as i didn't have the ability to 3d print so the enclosure wasn't made to fit my project
fix ------> i got the closest avaliable box in dimensions to the one i designed 125mmx80mmx32xmm and made holes manually using a hot knife
5-finished it with a nice layer of hot glue to make parts steady in place while running.
