Sorry David, should have been more precise http://www.youtube.com/watch?v=XtBpkSlC3Dg is you tube channel for Adafruit Industries Electrical Engineering. They are very heavy into open source software and hardware and for a 5 year old company, are making a big impact on the maker world. Their you tube presence includes "Ask an engineer", "Show and tell" for people designing their own wares, "Wearable Wednesdays", electronics you can wear, "3D Thursday", 3D printing news and ideas, and a whole lot more. Worth the watch.
