For your TUNES

Sometimes on a long flight we like to "put up pin 4" which means to listen to some tunes. Not everyones mp3 player can put out enough power to hear over the roar of the trensmissions. Here is a little device that you can build to amplify adio devices.

It costs under $20 to build. All of the parts can be purchased through Radio Shack. Radio Shack does sell one similar but I am not sure how well it works and it's cost is over $20. I have seen others for about $100 (wow).

The system also works well if you want to listen to your headphones while mowing the lawn. Add on a NoiseBuster noise cancelling headphones ($40) and you will hear nothing but music. Sure beats paying $299 for the new Bose headphones.
