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 â€œmelodiesâ€).
