What:

We decided to use a microphone to detect the public speaker’s volume and visualize the volume information by NeoPixel which can be served as a reminder for the speaker to use proper volume when they give speeches.

Where:

Classroom (Pod)/ Public Space (As Installation)

When:

Giving Presentation/ Rehearsal/ Practicing/ Party

How:

The NeoPixel will give speaker real-time feedback on their volume and voice visualization, and after the speech, the speaker can check their volume history on their phone which is able to help them improve for next time.

At the same time we were thinking about whether we could hang the whole installation, so that it would give the speaker real time feedback and it would hang on the wall as a work of art.

Prototype:

And then we put the model into the real background to see the effect.

Bill List:

NeoPixel

Electret Microphone Amplifier – MAX4466 with Adjustable Gain

Mini Illuminated Momentary Pushbutton – Blue Power Symbol

TBD: Adafruit Accessories Mini 8×8 white LED Matrix（maybe larger）

Frosted acrylic light diffusion tube

Interaction:

We’ve thought about a lot of ways to interact, and we’re going to do a follow-up experiment this week when we get the material together.

1.Lights flicker like flames to show volume

2.The light changes color with the volume of the sound (for example: the volume is small blue, and the light becomes red as the volume increases)

3.Simulate the curve of sound wave to change the position of light

Amplitude waves. Music sound voice wave. Dynamic equalizer

PIXEL COSTUME~

Danica+Baoqi

Our costume is inspired by the game Minecraft, and we will appear in the Halloween parade as two pixelated characters, one with an axe and one with a torch.

The cube is going to cover our head, upper body part and arms.

The first pixel girl with the axe has the block sequence around her(or in the other hand), she uses the axe to shut down the block by hitting the axe to the block. We intend to use a hidden switch to trigger this action.

And the top of the torch in the hand of the pixel holding the torch presents the shape of wave, visually represents the shape of the flame, and has a built-in light string.

Material(possible): Corrugated plastic sheet/ painting/ sticker(pixel patterns)/ boxes

use Wide Format Vinyl Printer & Cutter to print the pattern

BAOQI DING’s Plush Night Light

This project -FIRST DAY & LAST DAY- is about my feelings about New York and my impression of my hometown. It is a small device about memory. I pixelated the first photo I took after I came to New York and printed it on transparent fabric as my first impression of New York. My last-day impression of my hometown was related to the sea, so I combined the two to form the whole installation. This device is made for myself, and beneath the waves are my memories and emotions.
