Thu, Davonna, Naeem, Gordon

Project Description:
– Plays a song when someone walks by
– Lights up at certain parts
– Purpose: Children will use it and it will let them interact with the art
– Serve: Decorative art for plain wall
– Important Features: LEDs, Batteries, Painting
– Technologies: LEDs, Arduinos, Shopbot, Laser cutting

It will be a painting that looks like a bar from a music sheet where the lines is painted with conductive paint for the connection to make sound and LEDs light up. There will be different types of notes. Behind the music notes will be the LEDs which the circuits can be completed with the conductive paint. Where the ground is connected, a clef would cover it up to make it look nicer. Other musical thingies would also be added to make it look more musical. 

– Save electricity from the circuits
– Interactive
– Eye-catching (artistic)
– Incorporates different technologies
– Requires a lot of programming
– Need good sound quality for speakers
– Flexibility and Resistance for sounds

– Conductive paint
– Normal paint
– Cardboard
– LEDs (2-3 for every note)
– Steel Sheet
– Arduinos / Lilly pads (Modkit/Scratch)

Key Words:
Live Wall, MIT, LEDs, Conductive Paint, Scratch, Resistance,

Examples of Products: 
– Product has light circuits and conductive paint that is included in our project
– Product has lilypads/arduinos incorporated into the painting as our project will be
– Piano Stairs uses different placement to make sounds (resistance for us) and pressure to complete circuit

DYI Projects:
– Light Up Paper Houses -> Uses conductive paint to make a circuit similarly to our project
– Paper Electronics -> Uses conductive paint to create words but still in circuit which we can use to make it more creative
– PianoPIC -> Uses a micro-controller that includes inputs and outputs that makes sounds with LEDs like we will

Technical Information:
– Conductive Paint -> Learn about layering and how it works since most of our project is based on the connection of conductive paint
– Types of LEDs -> Need to know the different LEDs so we can decide which one is best to use for our project
– Types of Arduinos -> Need to know which Arduino is best for our project by looking at how they work
– Resistance -> Learn how resistance works on conductive paint
Steel Sheet & Rare Earth Magnets -> Find out if it’s magnetic enough to hold up the music notes and the cost

*Italicized words signifies changes as project goes along*
– What kinds of sensors is the wall using? – Infrared (maybe pressure) ** There might not be sensors now that the music notes can be moved around to make different sounds.
– How will you be able to tell if it is a person walking by or a door closing? – Sensor won’t be next to door or just dont hang the painting next to the door ** This question won’t be applied as there might not be any infrared sensors included.
– What is the project for? – Arts cause, decorative item, children’s use, make walls less boring and plain
– Can you turn it off? – Yes, with a switch
– Is it for the tech center or mass production? – Tech center — we’re only making one.
– How big is it going to be? – About 3ft by 9ft
– How do you install it? (because people already have walls) – It’s going to be like a painting where people can hang it up.

Day 1 (7/9/13)
– Made a very rough Prototype #1 of how the product is going to work
– Researched on MIT live wall, conductive paint, and LEDs
– Discussed the main features of the project
– Create a rough drawing of how the product will look
– Made Prototype #2 — more accurate of how painting would look (Idea of Music Notes)

Day 2 (7/10/13)
– Create Storyboard of a user
– Discussed what Programming to use (Arduino, Raspberry Pie, MakeyMakey)
– Create design drawing of how notes would look and where the light would be
– Create Prototype #3

POC Prototype:
– Concept: Programming with MakeyMakey instead of Arduino on Scratch
– Used copper tape to see how connection work (conductive paint later)
– Figure out how to make resistance to change sound
– Visualize how the final product might look and work

Day 3 (7/11/13)
– Used conductive paint to test if there is resistance between thin and thick layers and distance
– Create Prototype #4 using conductive paint 
– Programmed using Scratch determining the sounds that would be made depending on the resistance
– Multiple trials to see look at how resistance would work
– Draw out the circuitry of the notes and LEDs
– Draw Dream Design of project (how it would look from all sides)
– Calculated how big product will be and placement of each line and each ground 

Day 4 (7/15/13)
– Make Prototype #5 with a board (more accurate and more like design of project)
– Test resistance of Prototype #5 and make more layers to adjust resistance
– Programmed with Scratch to make sounds more musical and less like random noises
– Test batteries with LEDs on conductive paint
– Test different circuits to see how bright light would light up base on resistance
– Make cardboard music notes and test the circuits
– Researched on Scratch programming and different kinds of audio that can be used

Day 5 (7/16/13)
– Finish Prototype #5 by adding white background and making it look more like musical lines
– Make music notes out of acrylic from Fab Lab
– Make circuits on acrylic notes and see how bright it will light up
– Debating on whether to put light behind the notes or on top
– With music notes, test out magnets and see how it affects the connection
– Test how well Magnetic Sheet would work with conductive paint and magnets on the notes
– Decided that Music Notes can now be moved around to make different sounds

Day 6 (7/17/13)
– Finish note prototyping and fixing the circuits
– Make different notes to add for decoration
– Researched on Steel Sheet vs. Magnetic Sheet (cost)
– Researched on Rare Earth Magnets (cost)
– Researched more on types of LEDs (figuring which will light the brightest)
– Finish Scratch Programming making different lines have different sounds based on resistance
– Make scratch programming so that when you press the lines with your hands, it can also make sounds based on the change of the resistance
– Ran into a problem with the lights -> Adding batteries to the board changes the way the resistance works, thus messing up the whole programming
– Trying to figure out how to make a circuit that includes the battery on the note itself -> the magnet completes the circuit when it touches the conductive paint on the board
– Prototyped more notes to test out circuits with coin battery in it

Day 7  – Design Review (7/18/13) 
– Programmed second line to make different sounds from the first
– Made a successful note with a battery in it that actually completes the circuit when pressed on the conductive paint

Day 8 (7/22/13)
– Bought 1” by 2” Galvanized Steel Sheet
– Bought extra magnets
– Painted Sheet – Multiple layers of white paint first since the sheet is glossy
– Made more note prototypes

Day 9 (7/23/12)
– Painted conductive paint on white temporal paint
– Washed off everything because conductive paint was coming off with temporal paint
– Made clef prototype out of cardboard (actual size for the final project)
– Fixed note prototype 
– Got spray paint

Day 10 (7/24/13)
– Spray paint sheet over to see if conductive paint will stick better to the paint
– Make circuits on note prototypes
– Research LEDs

– Prototype #1
– Prototype #2
Prototype #3 (POC)
– Prototype #4 (Conductive Paint)
– Prototype #5 (Background Painted with Acrylic music notes)
– Design Pictures
– Storyboard
– Testing Resistance
