On the topic of adding sounds to the Delorean, a few years back I created a little device for #2860 that would make the "time machine door opening sound" ala Back to the future, when you opened the door. I got a sound chip from Radio Shack and burned onto it the sound effect taken from the movie. I then hooked this up to a little powered speaker (ran on "D" batteries) also from Radio Shack, I think, and then connected it to a door pin switch, and set the speaker on the deck behind the driver's seat. A fun, temporary little gadget for shows and things. You can build it in an afternoon for less than $40. The hardest part was capturing the right sound, which I loaded into the computer to remove background noise and to "punch" it up a little. -Ace Underhill- Brilliant Screen Entertainment
