This is my BTTF 2 jacket that I made from a few simple materials. But even though the materials were simple does not mean it was simple to piece together. Far from that. Anyway, here is the entire project.
First came the red mats. This was the hardest and most aggravating part.
Then the pockets. I couldn't find any dark grey foam, so I had to go with black.
When you wear the jacket it goes to the right shape. It looks weird when you set it down. Also the color is lighter and matches the color from the movie almost perfectly.
Then came the electronics. I just used cheap recordable greeting card sound chips. I don't have any pictures of the full assembly of the sound chips with the piece of the belt attached to it, but I do have a video.

I installed the speakers on the inside of the jacket and I had to cut a hole through the jacket for the button and wire to run through.
I also had to cut a slit on the bottom for the second button to fit through so it can be raised up enough.
And this is me wearing the jacket along with the hat.
