To share,  I really like to vist  ars technica for all my tech news  some of the news is kinda draconian but a good tag line will grab your attention every now and then.

found this old tripod website about how stereo audio is handled in your car, walkman, ipod (with attachment) and ect….

Its an old tripod website…that brings back memories.  I am using this article as some reading material to eventually build my own Ipod Itrip.  I am looking for a certain audio quality and I dont want to be able to tell if i am listening via the radio or if its a cd playing in my deck.   Many of the fm transmitters you can get at your local Worst-Buy and Ripoff-City are very cheep and give awful audio quality.  Worse yet they want like an average of 70 bucks!  Kiss my big….well you get the point.  I figure try an build one myself.  The advantages are i save a lot of money and I can advance my knowledge of signals and systems professionally.  I figure it would be a great project were i could actually learn something from that i could use later
