Valentine Heart Pendant with LED
Description
This Is A Small Heart Pendant For Valentines Day, With A Flashing Led And Battery For Interest Factor. It'S Meant To Be A Gift Or Personal Fashion Item. No Soldering Is Required -- Just 3D Print, Insert A Led And Cr927 Battery, And Assemble (See The Pictures In Post-Printing For Details; Note That Strong Finger Pressure Will Be Required To Press The Lid On, But It Will Fit And Stay In Place). There Are 2 Variations Of The Design: "V1" Has The Strongest And Most Secure Chain Loop But Won'T Lay As Flat As V2. "V2" Puts The Loop On The Structural Lid For The Best Balance And Flat Appearance, But Has A Small Risk The Body Of The Pendant Could Release And Fall Off. This Piece Is Designed For A 5 Mm Led Size, Specifically The Multi-Color Flashing Variety (Both For The Interest Factor And Reduced Current Draw On The Battery). These Can Be Acquired From A Variety Of Electronics Sources Including Amazon (Search For "Multi Color Flashing Led Electronics 5Mm"). The Cr927 Battery Is One Of The Smallest 3V Lithium Cells Available; They Will Last More Than 12 Hours In This Design And Are What Makes The Small Pendant Size Possible. They Also Can Be Acquired From Amazon (Search For "Cr927 Lithium 3V 3 Volt Coin Cell Batteries"). Altogether The Electronics Should Cost Less Than $1 Per Heart -- And In Bulk, Less Than $0.50. When The Led Stops Flashing It Means The Battery Is Spent; Just Replace The Battery When You Want To Activate The Pendant Again. *** Update: I'Ve Seen More Than 48 Hours Life From One Cr927 Battery In This Design.
