A few hundred years ago someone threw out an Edison voice recorder. You would speak into it and it would record on the wax cylinders. I brought it home and looked up its value on the Internet. I was suprised this particular model was not bringing in much money. I didn't have much room, and my girlfriend at the time talked me into throwing it out. Before I threw it out, I took the AC/DC motor out of the device. I just couldn't throw out that beautiful little motor. I now have that motor on my desk as a paper weight. People look at it, and ask why does it have a DC switch. I don't actaually know, but my thoughts were Edison was unsure of our electrical future?
