My girlfriend, a music buff, asked me to come up with a better way for her to look at the track information of the current song playing on her iPod touch while she was using it in the car. Those of you that have or have had an iPod touch know that it's not the easiest thing to read while driving. To see the song information you have to double tap the home button and then still the text is extremely small. Also, controlling playback is distracting as the iPod touch has no tactile buttons so it requires the user to look at the screen to find the location of the soft buttons.
My solution was to construct a device that would interface with the iPod and take the song information and then display it on a screen somewhere in the easy view of the driver. After quite a bit of work and research I finally arrived at the product you see here. My iPod information screen displays the song title, artist, album, song time, and play/pause symbol. It provides skip back, skip forward, and play/pause playback control as well as charges the iPod.Edit:
A lot of people have mentioned that some sort of volume control would be good to add. As it turns out when the iPod is controlled through the method used in this instructable, volume control is disabled. I suspect this is because this mode is meant to be used with some other device controlling all playback functionality remotely and so volume would be controlled with the device. In this case, volume is controlled with the car stereo's volume control.
