I got the Minty Boost kit for Christmas, so I figured I'd video the finished product. The high pitched sound you hear when it's plugged in is normal and related to the inductor. It should go dissipate after more use. See the FAQ (ladyada.net/make/mintyboost/faq.html) for more info.
UPDATE: I wiggled the inductor around a bit, and it severely reduced the high pitched noise.
what is that sound at the end?
