What the mobile does:
When the baby cries, a sensor inside of the mobile captures the frequency disturbance and makes the mobile lighten up. The moon will start rocking from front to back.

Materials needed:
DC motor
Gear Motor 3
Microphone
RGB lights
Cam
Light fabric
Papier maché

The movement of the moon rocking has been changed last minute. Up until now I had resorted to using magnets to avoid the use of motors (too much noise). But after revising the efficiency of the magnets and the potential issues arising from their use, I have decided to use a DC motor and simply frame it at the top of the mobile to choke the noise.

 

I have also done some research on the responses of babies at different ages.

At the moment I am leaning towards 6-8 months old babies. I will be gathering more accurate data from this age category and will be testing the mobile with a baby towards the end.

 
What works / is done
- RGB lights fading
- Switch
- Box (built, painted, mounted)
- Plexiglas layer (painted)



What doesn't work / isn't done
- DC motor > Rocking moon (CAM broke)
- Soldering wires & glueing lights on plexiglas
- Soft switch toy (isnt sewn completely)

final project proposal

Creating a mobile designed for small children and babies, that illuminates and responds to its actions (moving, crying, getting up, laughing).

The esthetic of the mobile will be thought through carefully: the colours will correspond to what the child is doing (different colours = different moods), the mobile will move slightly to distract). The purpose of this mobile is to calm the child down until he falls asleep and to develop his reflexes and awareness to what is around him.

Kevin's blog contains the video as well as pictures of the project.

 The concept of the hockey pinball was to reunite two games that almost everyone knows of, and give it a new twist in its gameplay. We chose pinball and hockey table because the first game is usually played in solo while the other requires atleast two players. Their basic rules being quite different, we wanted to combine them to create a 'new type of game' that would still be relatively familiar and intuitive in its rules.

Because of the nature of the game, the marble seemed the most appropriate object to choose from the list.

The first sensor we had used, the LDT piezo sensor, had to be dropped because its capacities did not respond well with our game: the marble would have needed to hit hard on the sensor to trigger the next move, which could have potentially damaged said sensor.

We opted for a photocell sensor and a narrow angled light to trigger the game results. The outcome was just as efficient, but not damageable for neither the sensor nor the physical box.

Exercice 3 ; Sense (take two)

After having scraped down the xylophone idea, Kevin and I have turned to a small pinball type of game.

The circuit that had been built for the previous xylophone idea was almost entirely reused, so all of it was not lost. It needs a few adjustments and nre components and the biggest part to do at the moment are the actual boxes. 

The primary goal is to slip a marble inside of the box and to roll it to the other side, where a light will indicate if it fell into the right spot or not. The use of the drum sensors will measure the weight of the marbles to trigger the light and the buzzer.

The sketch of the game as well as the storyboard are on Kevin's blog at the moment, they will be added here later on.

As of right now, we do have a somewhat functioning prototype. We are still missing three zener diodes, which are needed for our project to function properly (we are waiting for the pieces to be shipped).

Exercice 3 ; Sense

Kevin and I originally wanted to make a xylophone, but realized much later that it did not integrate any of the required materials (marbles, feathers, string or clay).

I met Elio and he told me that the sensor we currently had, the LDT Piezo sensor, might be an issue because of the nature of the project and the sensitivity of said sensor. He then suggested the drum sensor, which might be efficient for our project.

We therefore decided to use the same circuit idea but make our game into some sort of small pinball game for 2 players (one model each).

Here were the first drawings of the xylophone game, which has now been abandoned.

In relation to our next assignment, Kevin and I wanted to use the sensor and integreate it into our windmill.

We would be working on the concept of wind making the pals turn (in our case, when we blow on it) to create more interactivity.

The sensor would most probably be located at the top of the windmill, and we would be adding light sensors inside of it.

Exercice 2 ; Animate (take two)

After trying to build the circuit, get the materials and assemble everything, Kevin and I have faced a few issues, one of them being 4 servo motors needed and more programming than we could manage to make for the moment.

So we've decided to redo our project.

The basic idea was to recreate a windmill.





 Here are the materials needed:

- Servo motor
- Arduino
- Wood (to create the windmill)
- bolts
- glue
- paint
- wires
- LED lights (for the inside of the windmill)

- possibly a sensor to capt any movement and change the polarity of the windmill's direction.

The approach was to create a relationship between elements, such as wind in this case, and humans interacting with it. The idea that a decoration object can respond to a user's presence the way it would respond to nature (wind) was our focus. In this sense, we wanted to recreate and ironize the human factor disturbing the windmill when only nature can in real circumstances.

here are some references we've looked up:
