In reflecting on how to utilize ambient sound that adaptively changes, I’ve decided to use a modular synthesizer to generate sounds. I had toyed around with the idea of using an mp3 playing device that would work with an Arduino, but I realized that the technology involved with those wasn’t as fully interactive as I would like it to be. My goals for this project are for the actions of the user to have a significant effect on the sound.

I will be using logic chips for all of connections, and these will be connected to the board to be cut via a alligator clips, and the output signals of these logic chips will then be sent into the inputs of the Arduino. The Arduino will send out voltages through an Adafruit Quad DAC which I have ordered and I will be able to connect to the synthesizer via these audio jack parts. In the link is a demo of the kinds of sounds that can be made and changed.

Ambient Sound Demo

Here is a diagram of what I want the setup to be like! I do want it to be a dark and isolated experience so the user can focus on what they are doing. For documentation purposes, I will be recording a video of myself at home working on this.

Here is an example logic problem for how a parameter of music could be changed.

• I have been working on finding the right configuration, spatially, for the dance box. The base dimensions I have decided on is 36″ by 36″. There is no specific height, the ceiling height will determine the top of the box, this is somwhere around 10′-11′. I have been using objects from around the house to define trigger points/areas as well to constructing physical boundaries that cannot be crossed by the dancer.

Testing out physical space set-up and dimensions.

These knit ropes will be used as another switch, they will create two sides of the box. They will have conductive thread going through them so that when both are touched simultaneously, they will act as a switch signaling for something else to happen.

The electronics I will need include: AND gate and an OR gate.

Draft version of Cut, made using cardstock and conductive tape to create circuits. In essence, all circuits start ON (1), except one involving the scissors,  and breaking them (0) triggers a reaction in ambient sound created from the experience interactively.

The side which starts the experience is labeled at the top “START”, and will be cut using specially created scissors to interact with it. Breaking the start circuit will begin the the output of music. Cutting along the dashed lines, at forks in the path, the player will be given prompts to choose a direction to go down cutting. Certain circuits are cut (turned off) to trigger an effect. Others are created through the act of cutting itself, because the scissors also have conductive tape on them that connects the blade of the scissors to the hand. The body is then used as a connection in itself to the other end of circuit. Therefore, circuits are actively created throughout the piece. Eventually the other end of the sheet is breached (labeled “END”) and this stops music playback.

Connections on scissors labeled below.

Multiple logic operations will be used through combinations of the different circuits. Here is one example of how one could work.

Word Equation(s):

Q2 AND (NOT Q1) AND ((NOT Q3) OR (Q3 AND Q4)) = Output 1

Q1 OR (Q3 AND (NOT Q4)) = Output 2

Truth Table(s):

Can I come in to work?

Will I get fired if I come in anyway?

Schematic:

Using an Arduino and logic parts, build a device that takes 4 inputs (one of them being an extra step—inputting the code to disarm security) and has two possible outputs (with a possible secret third output). The inputs are as follows:

Q1) Are you sick? If you take a tissue, then you may be sick…

Q2) Are there jobs to do? Consult Slack for that… that’s just going to be a pushbutton for now…

Q3) Is Hunt Library open? Real-time clock controls that input.

Q4) Can you disarm security? More just a joke part, input some 5-digit code into a keypad.

If you are sick and decide that you’re coming in anyway, play some fun (but menacing) sequence corresponding to you getting fired for violating COVID policy.

If you fail to disarm security, then play some funny sequence of getting arrested by CMUPD and getting fired for trespassing. Have Cody Soska record a funny voice clip of saying “WOO WOO, this is the Crops! You will be the one behind the bars!”

Needed materials:

Arduino Uno R3 (for sending hi/lo signals through logic chips, and handling RTC and keypad inputs…)

Breadboard or protoboard

16×2 I2C LCD screen (debugging purposes only)

Momentary pushbutton or toggle switch

Applicable logic parts (74xx)

10 digit keypad

Breakbeam sensor (for sick test)

Wires (have, though may need more depending on cable management)

Soldering equipment (have).

Some acrylic or plywood to laser cut an enclosure for certain parts if applicable.

Scale: Installed in my bedroom with parts strewn around the room (NEATLY, please…).

General flow of the device’s workings…

Sketches and images:

Overall layout (NOT TO SCALE)

Q1 Location (right side of bedroom door frame)

Q2 Location (left side of my desk)

Q3 Location (nightstand, far side of my bed, main logic may also reside here)

Q4 Location (keypad, side of bookshelf on near side of bed)

Some preliminary measurements were taken, but I’m going to measure again. As they say, “Measure twice, cut once.”

UPDATE 09/28/2020: I still need to acquire a keypad. Additional wire may also be necessary, but that depends on what the final measurements turn out to be.

UPDATE 09/30/2020: Have procured a keypad and IR breakbeam sensor. All that’s left to procure are the necessary resistors and any extra wire needed outside of what’s provided in the kit. Q1 may be moved next to Q4 to streamline the flow of interaction.
