Some of you may have seen my NES Controller MP3 player. This is a companion project for it. I sometimes like to sit around and listen to music so I made these powered speakers. And since it was to go with the NES controller I made it in a NES cartridge.
Now before you even read any further. These are not really loud. Just so you know. They are great for sitting at your desk, but you would not want to have them as music for a party or anything. Now you could make a larger more powerful amp, but I didn't. Just FYI.
Here is a video of it playing with the MP3 player I made.
