Not sure if this will make it through the mods, but it is partially DeLorean related. I remember awhile back there was a thread discussing that some owners wanted to have the BTTF door opening sound integrated into their DeLorean. Well, I've finally gotten around to playing with my ISD1000A audio record/playback chips and I think it would be quite easy to do some fun stuff with it. The chip can be configured to play once when a switch is closed, or loop continously as long as it is closed. While I'm not familiar enough with the DeLorean to know how you would attach some sort of sensor to close a switch from the time the door begins to open until its fully opened; I do think that you could possibly place an infrared emitter and detector underneath the shift boot. Each time then, that the shift lever passes from one gear to another, the infrared beam would be crossed, and this could activate a switch on the ISD1000A to play the BTTF shifting sound. Some of you may be familiar with it, it sounds cool :) In any case, I've been lucky enough to salvage these chips from some of the Radio Shack stores up here for a mere $4.97. If anyone has, or is willing to record the shifting sound from the movie, please email it to me: supermatty(at) psu.edu. I would be more than happy to wire up a circuit for testing if someone would like to try it out in their car. As I said, I don't have a DeLorean myself yet or else I would. thanks, Matt Spittle
