1，When it is rainy or windy outside, we always feel depressed or a little bit afraid. But what if we just imagine the wind and rain are just talking to us. So I want to design a device that sticks on the window. There is a humidity sensor or press sensor? inside it which could translate the beats of the rain and wind to some emoji showing on the screen or some cheerful music.
2, A drum that can show the drumbeats. It is used when teaching or improvisation. The drums are connected. So when one beats on the drum, the other’s drum will have a led signal, so they can follow the first one. I am thinking if the device is better for teaching a single drum or the drum set.
