Corrections And Updates !
Finallllyyyy ! This is complete now and is good to go . I am veryy beginner in ts so I took a lot of help from Souptik vro and on electronics who politely helped me.
I added copper plane on both sides of board . Moved antenna out of the board and mad CAD changes to protect it so i Can add bt and wifi from future updates . I also did changed routing 4 times and I can feel the progress and confidence now . Finallyy ! The last Journal .

Your PCB routing needs significant improvement as it is currently quite messy and may cause issues.
The high-speed data lines are not properly length matched. These should be carefully matched and impedance controlled to 90 ohms .
The ESP32 antenna layout is incorrect. There should be a proper keep-out zone with no copper or traces under or around the antenna area.
There is no proper ground fill or ground plane, which is important for signal integrity and stable performance.
Overall, the PCB layout is inefficient. The board size could be reduced by tightening component placement and improving routing.

GitHub !!
Finished Github Repo work , I hate this work cause it's so boring but still I took a lot of rest before this last journal because I had to attend a family function to I left . However , It's done now and in a very muchh organised way .

JLCPCB !
Just Did JLCPCB Work and got the estimated value ~85 as 70 usd for pcb and 5 for esp32 and 10 for CAD shipping from printing legion .
Now gonna do GitHub work

CODE 😎
Hey wssp ! I finished with the code and really , ts was tuff even after my brother helped me out in this , I need to use AI a lil bit to finish it , although it was below 30% so don't matter while approval .

CAD UPDATE !
In hurry to finish CAD , I forgot to make the buttons for DPAD so i made made one , it wasn't difficult or timetaking but i was feeling too tired to make that , SOoo , i have made it and also created a assembly
Looks Great Overalll , Yayy XD !

CAD
Started Working with bottom part first as it was easiest for me as i am a rookie at CAD and need a good pc for gr8 softwares so i used FreeCAD which I always use in my projects which can handle small works with ease . But then also it Was pathetic making the base part only .
Just finished making bottom .
Next, I worked on TOP plate and journal about that in this too as i forgot to do that earlier.
Top part was a real hell as I made a lot of pockets and measurements for making top part , was much difficult than Base part. However , I completelyy finishedddd ittt .
According to me now, all the work is finished and just the JLCPCB and GitHub needs to be done . Lets hope for the best .

Routing
Routing Wasn't Easy at all , difficult as hell as I needed to place the Components close to save space for display mounting and I've also added some silkscreen images to make it look more cool . I have placed the components both on upper and lower side of the PCB in order to make it small and organised , most of the image is consumed by TFT display only and rest by buttons . Afterall , it's now complete and is ready to move forward to CAD work which would be more difficult and time taking because of my potato PC . Nvm lets move forward with hope that my PC won't blast .

Correction For Schematic
I forgot to add switches to control the MP3 Player in the schematic so I added them now by modifying the schematic . I'll try to avoid these sort of mistakes from next time ...XD

Schematic
This had many connections nd wiring them was a real hell , some are there whom in don't even know about so I needed to dearch about this , I have constantly been working for 3 hours on this to finish this . Although this was difficult , it led me to know more about pins and wiring so it was fun to do thatt along listening to my playlist . :)

CyberSter is about making a portable MP3 player using different electronic modules. It can play music from an SD card and send audio through AUX or Bluetooth. A screen is used to show the menu and song information. The device also uses a Type-C port for power and transferring music files.
I wanna build it for listening music most of tht time I travel because in India , most of the places where we travel are remote and don't have network also It's pathetic to download music andd store in a mobile .
I decided to have a Advanced MP3 player with A big enough display , sd card for input , bt support , Aux cable and Type C for charging and Data Transfer .
So this is a BOM i made and used CHAT GPT to generate in a porper table form .
Next Thing I'll do is PCB Designing .
