DIY Active Noise Cancellation
Noise cancelling headphones a pretty cool, but are ridiculously expensive. I've been thinking about the plausibilty of making a little box w/ mic that generates "anti-noise" (inverted or out of phase waves to use the non-buzzword terms) that converts normal headphones into noise cancelling ones. Realisitic? Anyone know of someone who has done this? Am I crazy?
