WineGong – a ‘wine glass door bell’

Nice remake! Kui writes –

Long time ago i saw this unusual door bell at the make:blog. I loved the idea instantly! Even though the project is quite simple, it took me one year (sic) to get it done.

I didnt like the concept of using a electromagnet for playing the sound. I preferred a servo motor controlled by a microcontroler (Atmega8) to do the job (side effect: programmable “melodies”).
