Sound Projects
CONTEXT: Smart Object, MFA Products of Design, SVA
Project 1
Timeline: 1 week
Voices of Winds
Material: tinfoils, matel wire, fan
Due to the fact that tinfoil is extremely thin and light-weight, any light movement will make it rustle. This feature made it a perfect material to capture the sound of wind. The form is inspired by plants as they are the natural instrument of wind.
He Ye
Material: tinfoils, matel wire
Inspired by lotus leaves (He Ye). The tinfoil balls are used to simulate water droplets rolling on lotus leaves



Final Project
Brainstorming

When the quality of time increase, the speed and value of time increase as well, and the existence of time become hard to notice and vice versa.
Tick-Tock
The volume of tick-tock will change with time. The hour hand can act as a rotary knob to control the volume.

Plan
The first way to achieve that is to add a player behind the clock, and control the volume by a ESP8266 connected to wifi. The second way is to add a loudspeaker behind the clock and amplify the sound of the clock directly. The problem with this one is that the volume can only be changed through a potentiometer.
Network ESP8266 with Firebase
Build the physical clock.
Get arduino to playback WAV file on buzzer using PCM library
Build website for controlling important times

Development

1st Attempt

Problem:
No DAC pin in ESP8266 - poor sound quality.
2nd Attempt


Problem:
Audio library is not compatibility with ESP32 - can't adjust volume.
