i bought a squeaky mouse toy for cats that squeaks just like a mouse when bumped or wiggled and i'm wanting to change the circuit so that will sqeak once every 2 or 3 seconds without being moved. i took it apart and found a small black cylinder shaped thing that when moved triggers the squeak, it has 2 small wires coming from it and if i take a screw driver and jump across these 2 wires it will squeak continuoisly and thats not what i want so anybody have any idea's about what i need to do so it will work the way i want it to.i don't anything about electronics so be pateint when explaining it to me.
