You just BETTER be glad that I never throw anything away!!!! Icon_lol Icon_lol Icon_lol Icon_lol

The only connection I'm not sure of is the "Blue line" connection of the Piezo Speaker (Red dot)

Piezo Element 1500-3000Hz
catalog #: 273-073

TLC555/TLC555CP LinCMOS Timer (8-Pin DIP)
Model: TLC555/TLC555CP Catalog #: 276-1718

0.1µF 50V Hi-Q Ceramic Disc Capacitor Pk/2
Catalog #: 272-135



   

ALL components were bought at Radio Shack. I think there is a variable resister that is needed, but I'm not sure. This was tossed in the junk box and the speaker was off the board, so i don't know if there is anything else missing, but I think it's complete as is. I ran it with 2 D cells in series Smile
