In addition to the work above, please include the following: 

1. Evolutionary history of your feature. 
2. For precedents: look for precedents both in nature and in human engineering
3. Slides for initial sketches/diagrams should include all 3 sketches that each person made at the start and explanations for why each was chosen or not chosen. 
4. After iterations and daily progress, please have a slide or 2 showing the plans for going forward.

Wednesday game plan:

• Read through the feedback you received in the “Exercises” > “Peer Critique” > “Response” tab. 
• Synthesize all of the critique you received from your peers into a written bullet list in your sketchbook.
• The goal for your prototyping today will be to address as many aspects of the peer critique as possible.
• By the end of the day, you should have made plenty of iterations to your prototypes that take most of the critique into consideration.

This was the first design. The main wooden "stem" with all the metal "leaves" on top will stick out through the middle. All the electronics will be connected through the central hole down a hollow cylinder to the bottom of the water collection tank. Water will drip down the leaves into the funnel and down the sides, leaving the electronics connected in the middle intact.

Major breakthrough!

We plan to create a superhydrophobic surface with semi-hydrophilic bumps attached to a metal plate that will be potentially cooled down by semiconductors. Water droplets will condense on the hydrophilic bumps and, with a bit of shaking or tilting, roll down into a container below through contact with the superhydrophobic surface.

We found the perfect material for this job: pieces of interlocking foam tiles with tiny bumps. Firstly, we will cut the foam into thinner pieces and spray its surface with hydrophobic paint. Then, by coating a roller paint brush with a thin layer of paint and carefully going over the foam's surface, it can only make contact with the bumps and leave a layer of hydrophilic paint on it. See the images above, where the dark blue paint represents a hydrophilic coating, and the light blue paint represents a superhydrophobic coating.

Our next steps are to design and 3d print the collection system, make the electronics using Arduino, cut out metal plates that will be attached to the foam, and, most importantly, decide on what types of coating we will use.

Today, we posted precedents and began working on our actual prototypes. Nathan worked on the camouflage LED lights, while Geraldo and I worked on the actual prototype and posted precedents.

On the first day, we decided what to make for the project. We are creating an armadillo backpack and a camouflaged jersey that will be attached to a color sensor in the backpack. The color of the jersey will change as the background color changes. By the end of the class, we had completed a rough prototype and created a sketch for it.
