need help please Answered

I am trying to build an art piece that is a book, and when you "pet" the book, it will make a sound. Can anyone talk me through how to make this happen? If so, please make it step by step for dummies. thanks!!!! J

I saw something along this line many moons ago, where a plush toy was made to respond to touch or caress. The circuit was way complex beyond my capabilities but the touch pads consisted of the statically conductive packing material used with shipping some sensitive parts. The problem is, most of it is no longer very conductive anymore.

The Schematic is probably listed in the archives of Nuts 'n' Volts but it will take some skill to solder this one without an etched pc board.

a thin sheet of packaging foam with holes and aluminium foil on both sides make a nice switch a bit less reliable though (stucks in the on position after some not very long life)

Search instructables for fabric switch, the book cover will be one big switch that is pressure sensitive or make some spots a separate switch. It should be enough to trigger a sound module. Get one of those "My Lil reminder" as seen on TV handheld voice recorders or similar memo devices and hook up your fabric switch to the trigger button. When you press or pet the book it should play back the recording. The thing with these recording devices, such as a Staples That was Easy button or the My Lil Reminder, pressing the button many times causes it to replay immediately sounding like a rapper or a disco tune. It would probably be advanced to do circuitry to lock out multiple switch presses. Good luck.

think of any 2 metal pieces of your choice (for example aluminium foil) now think how to make them touch each other exactly when you want the sound nd not touch otherwise from here on itll be straightforward
