One design element that interested me were the layers of plastics and protectants on the screen.  I assumed that a phone without a touch screen would just have fewer things on it.  

I was also very interested in the dial buttons both in plastic and in silicon.  I have never thought about what the keys looked like in a phone and how they interacted with the circuit board.  And I was surprised to see how the keys are thinly laid out in injection molding plastic.

I would say overall that I was surprised at how few parts were in the inner portion of the phone, and how the majority of its volume is plastic.  I often think these phones are too light and I assume that the designer made so much out of a light plastic for cost reasons.

Hi, I’m Stephen

I am originally from Pittsburgh, PA, and I have been living between NYC and LA for the last five years. Before PoD, I studied Photography and Latin American and Iberian Studies at Bard College. I am really interested in, and plan on centering my design practice on social and racial justice.

I really love to photograph with my large format camera as well as go to movies and biking. Traveling is my favorite activity, and I love to go on road trips or impromptu vacations. I don’t have experience working with Arduino, but I am really excited to start making in this class!
