I have a friend that always has on sweet belt buckles and he is very proud of them. He has one that looks like a really small Ghetto Blaster, but it doesn't play music. So some of us where talking about how cool it would be to have a belt buckle that plays music. I thought to myself that it wouldn't be that hard to make.
I have put about 3 to 4 hours into this over the period of about a week.
If you have any questions just ask.
