For now I'm working on the presentation things. We were making a finalized version of our proposal, perhaps more of a design. I have figured out how to use EAGLE and made a circuit diagram for our device. I found libraries for the Arduino shield, resistors and transistors. I used a barometer library instead of a Wii Nunchuck since it uses the same I2C serial connection. I also could not find solenoids, so I used mottor instead.
Regarding the sketch up renderings, I am preparing X-ray views of our tactile display and box similar to the ones in our proposal and presentation.
