How Do Microphones Work - Carbon, Dynamic, Ribbon, Condensor/Electret

So first, we like to occasionally take a look at things that connect to cables, and microphones are an important group for our customers.  

Second, we've got a video here with a lot of in depth information.  It's from a YouTube channel we follow called the EEVBlog, which is for electronics engineers, hobbyists, hackers and makers.  It's hosted by Dave Jones, an electronics expert from Sydney Australia.  In this episode his guest is Doug Ford, the former head designer at Rode Microphones.  Together they cover how different microphone technologies work including carbon, dynamic, ribbon and condensor/electret types.
