Grupo tres!

Day 1:

Let us find a problem…

First group discussion of the week...

2 hours later… We pretty much have a specific relationship target group! (Unfortunately we cannot find the photo of our brainstorm… But we brainstormed ideas across two whiteboards!)

Day 2:

We narrowed our customer definition and we decided on a concept.

Coming up with concrete ideas...

We also experimented in class with conductive threads to work with different pressure sensors.

Playing around with equipment...

We managed to knit a sock that was sensitive to pressure changes -LED brightness was affected by pressure exerted by the foot.

Day 3:

We fine-tuned our design concept, finalising the details and going on to design development.

Working on our powerpoint presentation...

Squeezing in some time for food (while working!)

A final design idea was decided upon and presented to the rest of the class.

Working out the programming details…

The evening was spent finalising the details of the programming and circuitry needed. The timing and order of all the different outputs had to be coordinated in the simplest way possible.

Day 4

Major change in plan for the design of the slipper – voice messaging had to be discarded because it was directly against brief specifications. Instead, we decided on using scents as a link to home. This meant a big delay as we had to reorganise the circuitry and programming.

So later that day, construction of the slipper began…

Fabrics and thread had to be chosen carefully...

Slippers were dissected and taken apart...

Push-sensor buttons were sewn with varying hole sizes - we had to experiment with different sensitivities

Testing button sensitivities...

Judy designed the aesthetics of the slipper – the design had to coordinate the metal snaps and speaker on the front of the slipper

Final chosen design


 Day 5:

Construction REALLY started today…


Usama and Cyril worked on the circuitry…

The final design for the slipper front... The stencil was then scanned and used with the laser cutter.

Transferring the design onto vector graphics....

Using the laser cutter...

Back from CSC Labs!

The cut design was then transferred onto the slipper, and snap-button connections sewn on...

The back of the circuit...

Day 6:

Things started getting complicated today!

http://www.objectdna.com/workshops/wp-content/uploads/2011/10/Connective-stitching-1024x768.jpg 1024w" sizes="(max-width: 300px) 100vw, 300px" />

A bit of complicated programming going on... Usama, Matt and Chandra "cheat-proofing" the alarm.

Annnnnd success! The alarm only turned off if pressed for more than 5 seconds...

The amazing Ramesh... Where would we be without him? The reason we have pizza at 2am :)

And a little craziness was abound... Guess that's what happens with lack of sleep!

That's until you look underneath the cover...

 With the brunt of the project done, we progressed onto our presentation for tomorrow…

Judy working on the presentation...

In need of some caffeine...

Practising our presentations...
