#100 *I made some mistakes in the first release of this video, which where correctly pointed out by the viewers (thanks for that!); couldn't leave things that way so I had to fix it...

In this video I try breathe some new life into an old device. I have an old AM radio, but there is not much to do with it; not a lot of stations to listen to anymore. So I build a circuit to transmit an audio signal from the PC to the radio using an AM modulator.
