NES MP3 Player Prototype 1

One day, I stumbled upon this site:

At long last, it was a NES MP3 Player tutorial... of sorts. It suggested the use of the circuit boards with holes in them and tiny tract switches to control the MP3 Player and at the time, I found an MP3 Player that has no screen. So it solved 2 of the 4 problems. With that, I bought a glue gun (this was an impulse buy but little did I know how vital it would be later on), circuit boards and tract switches and ended up with this:

Which further mutated into this:
Can you spot the many things so wrong with it? Yes. The USB is missing so I was stuck with the same songs I loaded onto it when I got the 256mb MP3 player. Not only that, the battery had to be soldered so everytime the battery died, I had to get my soldering iron to desolder and replace the battery, risking the thing blowing up in my face. On the brightside, this was my first NES MP3 Player and as I held it in my hands, I was smiling like a father with a newborn... albeit a newborn with defects.

The circuit board and tract switches was one idea that could've worked but when I tried it on mine, the thing kept shifting so that only the right D pad worked and the left D pad didn't. In the end, I ended up gutting it and recycling the parts. I still had 2 questions to answer which was, "how am I suppose to power it" and "how am I suppose to transfer music". Both answer as I found out would come easily when I found a second hand MP3 player.

Also, here are some more pictures which I took of the first prototype before I removed everything to be reused again.

Funny story. The wires in the last picture were from the NES controller cord wires because at the time, the cords were about to be thrown away and because I was running out of wire. Although the intention was good, the wires were still too thick to work with so I had to order some 30 AWG wire which is almost as thin as human hair compared to other wires I used.
