Week 9 Work Check

Group Critique Session - Work Check

* Decided to build sound-based and light-based portable installation.

* To 'Do' :

- Sensors : soft switch (mat) or photoresistor, see which one works the best.

(If the soft switch (mat) is used, decide on the size.)

- Figure out how the light works on daytime.

- Build a life size light pole including the sensor.

- Decide on the light (intensity, colour and power) - user test.

(because it is a portable installation, power source will be based on batteries, Andreas' suggestion will be using LED for the light).

- Decide on the sound (what sound works) - user test.

- Decide on size and type of the speakers.

- Figure out how to playback the sound (computer/ cassette recorder).

- Decide on the structure of the poles.

- AT LEAST, LIGHT-BASED LIFE SIZE PROTOTYPE SHOULD BE DONE BY 02/10/08.

* List of problems to be sorted out.

The End of the Workshop

Final Day

*Presentation

* The cable tack doesn't work.

* Zul suggested to use masking tape, but it should be cut nicely and tidy.

* View from left side of the pillar.

* View from the back of the pillar.

* View from the right side of the pillar.

* Final Setup.

* The sound workshop and collaboration work end here 25/09/08.

Troubleshooting Day

Set - Up

* After soldering every cables to the walkman's board.

* Closing the lid of the walkman.

* Front view.

* Back view.

   

* Masking taping the cables.

* Cables that are too long are tied together and masking taped to the wall.

* Photoresistors are taped in low position.

* There are 4 photoresistors in total.

* Each walkman is connected to 2 additional speakers and 2 photoresistors.

* Creating patterns on the wall using cables.

* Walkmans placed at the back of the pillar.

* Problem occurs :

- One of the photoresistor doesn't work properly.

- Probable mistake : loose connection, mistake in connection points.

* Zul helped out solving the problem.

* One of the photoresistors works only if its partner (from the same walkman) is working (covered by shadow). 

* The photoresistors work in a very short range, meaning user has to walk really close to it to trigger a change in the sound.

* Zul's idea : make a black tube to narrow down the range, so it won't take lights from everywhere.

* Try out set up.

Experiment day

Sound Modification, Installation and Interaction

* After the opening of the walkman. 

* Modification of sound can be experimented using either alligator clips or wet fingers.

* Teammate : Tienny Setywati (Animation Art student).

* The interaction lies in the photoresistor (LDR).

   

* Left image : mine.

* Right image : Tienny's.

* Decided mine would be sound modification in pitch and Tienny's would be sound modification in speed.

* Alligator clips as the marks where sound changes.

* Each group will get 4 additional speakers, which make 8 speakers in total (4 additional speakers and 4 speakers from both walkmans).

* Mounting the speakers on the pillar.

* Measuring the length of the wires needed.

* Red wire for positive, white wire for negative.

* Tienny's suggestion on the colours of the wires (red and white cables represent audio colour in television).

* Decided to place both walkmans behind the pillar.

* After measuring, soldering the wires on the speakers.

* Black wires used for photoresistors' cables.

* A photoresistor connected to two cables.

* Measuring the length of the cables, try mounting the photoresistor on the pillar.

* Soldering the speakers' cable on the walkman's board.

* The experiment ends here.

Media Integration Week

Week 8 - Sound Workshop

Lecturer : Zulkifle Mahmod

* Each student received a walkman.

* Record sound around the school and its surrounding for approximately 2 hours.

* Team up with a friend (2 students in 1 group).

* Teammate chosen : Tienny Setyawati (Animation student).

* Choose a site in block G level 2 as the installation site.

* Site chosen : A pillar next to room G203.

* Installation site chosen.

Week10 Processing

Visual Presentation

* Time :  Week 10, 08/10/08.

* Presentation on a screen-based work using sound (microphone) or movement (camera) or both as the input.

* Work : concrete object (on the screen) or abstract visual. 

Prototypes

Series Prototyping

* A box as the sidewalk.

* The size is similar to the first prototype.

* 3 boxes for 3 prototypes.

*  1 of 3 - 180 degree Rotation

- How it works : As a pedestrian steps on it, it will slowly turn (180 degree) and pedestrian will arrive back to his original position.

* Pieces of circles as the rotating board.

* Top/outside view, a hole to hold the pivot.

* Inside view.

* A toothpick as the pivot.

* Pieces of circles (material: art card) are stacked together to create a stronger board.

* Pivot is glued at the base and masking-taped.

* 180 degree rotation prototype.

* 2 of 3 - Light (Flame of Life)

- How it works: As a pedestrian moves/walks toward the edge of the road, light gets dimmer.

* Materials.

* LEDs.

* Bright light, placed in the beginning of the path.

* Low resistance resitor.

* Dimmer light, placed in the middle of the path.

* 2 low resistance resistors.

* Dim light, placed in the middle of the path.

* 2 lower resistance (than the before) resistors.

* The fourth LED is just as an LED with no power supply, placed at the edge of the road, end of the path.

* Connection of the lights.

* Soft switch learned in Wearable Technologies class.

* A carpet where the pedestrians walk through.

* Triggers light.

* In the making of the switch.

* The fourth row has no use.

* Conducive fabric sewn on the cloth.

* Connecting the cable to the cloth.

* Light holders.

* 4 big holes to hold the light holders

* 3 small holes to insert the cables.

   

* Cables from the cloth are inserted into the small holes.

* Outside and inside view.

   

* Light holders are inserted in the big holes.

* Outside and inside view.

* LEDs are inserted into their holders.

* One cable goes to the board, the other is attached to another piece of cloth with conductive material sewn on it (top cloth).

   

* Outside and inside view.

* Cable extension.

*Inside view.

* After connecting.

* Top and bottom.

* Outside and inside.

* Light - Flame of Life Prototype.

* 3 of 3 - Sticky Floor

* A hole on top of the box to place the flipping floor.

* Holders of the flipping floor.

* Holders are attached to the box (Inside).

* Flipping floor.

* Sticky floor, using double-sided tape to simulate the sticking part.

* Sticky flipping floor attached on the box.

* Traffic lights stands, 6 pieces to make each stand.

* Traffic lights.

* Prototype of 180 degree rotation.

* Prototype of sticky floor.
