    This is one of my latest cars I recieved from in the mail from e-bay. When I got it and took it out of the packaging, I noticed that the car was heavyer that a normal car with weights. I opened it up and found this stuff in the pictures below. Anyone have any ideas or clues on what this thing is?? There is a hole cut out in the bottom of the car floor with a switch to turn something on or off but it dosn't work.

    What it does is makes a sound like a mechanical reefer running.
    Is the black wire from the battery connected? I can't tell from the photo.

    Did you not read the item description on ebay? Or did you just buy something without a description, hoping all is well? hehe ;)

    By the looks of it, it must be homemade.With parts made from Radio Shack(Isn'tArcher a Radio Shack item?).
    Just a guess.

    I remember an article in one of the MR mags on how to build that circuit.
    That's how I recognized what it was.

    lol, there is a 555 IC in there. i remember them because when i was younger i used to tinker with that radioshack electronics learninglab. Never did figure those IC out, but i bet if i did, i could build my own sound decoders, lol.

    unfortunately, radioshack no longer sells individual parts except in stand alone radioshack stores. if its attached to a mall, the seperate parts are no longer there.

    I'm sure the article was in RMC about 15-20 years ago. I bought all the bits (including the 555) but never put it together as the fellow whose layout we operated on moved.
