What’s good this week? Let’s see:

Mohammed Samji takes us through a hifi power conditioner supplying electricity to some very expensive B&W speakers. Interesting! [Part Time Audiophile]

Break something plastic? There’s a plastic welding kit for that. Looks like it could come in very handy for radio cabinet repairs, among other things. [GeekWire]

The Broadcast Law Blog takes us through some of the changes that are in the FCC’s proposed AM revitalization plan, including reducing the protections afforded to the historical Clear Channel stations to let more local and regional broadcasters in. Public comments end on March 21st! [Broadcast Law Blog]

Dave at EEVBlog gives a great overview about bypass capacitors. What are they, and why are they important? Worth watching. [EEVBlog]

Brian Dipert over at EDN tears down an Amazon Dash Button. There’s a surprising amount going on in such a small package. [EDN] Creative Electron takes it one step further and puts the Dash Button through an x-ray to see the inner layers, too. [Creative Electron]
