I'm hoping that there are some electronics guru's here who'd be willing to help me with a project. I'm building a 'UFO' for a halloween lawn decoration. I've got two kid size swimming pools which I plan to glue together and paint silver. I plan to use some dowels to create a tripod stand for it. I'll place some LEDs around the perimeter. I'm going to cut a 3" hole in the bottom and have a fog machine to place inside. I then have a light globe to place inside which should give a nice effect on the fog as it comes out the bottom - multi colored light beams. Here's where I needs some help: I want to create a 5 tone sound and light pattern that repeats every 2-5 minutes. I want the lights to synchronize with the tones - and the tones will, of course, be the familiar five tones from 'Close Enocounters'. Trouble is, I have no idea how to go about this. I went to my friendly neighborhood Radio Shack and asked for help. The salesman had no idea either - then offered me cellular service! Can anyone here tell me a way to do this in simple terms a numbskull like me could follow?
