I was just looking at that page and wondering, is it possible to attach a radioshack speaker to that (http://www.radioshack.com/product/i...&kw=speaker+component+parts&parentPage=search) and have it play the frequency? So then my other question is, what is the formula for time it takes an inductor to charge. I suppose I would have to find some of my more massive resistors to do this in an audible range, as all of capacitors are in picofarads... very low picofarads
