Images of Final Project:

Description:

Our Project for Surprise is a little creature we call Mike. Mike is a small mouse, and he copies sounds whenever a new tail is added to him. Each tail comes from a different animal, and Mike attempts to mimic how they sound. On occasion, Mike might may sound quite different. To add the tails, simply attach them to the black tail nob on Mike’s posterior. Mike will respond by making noise.

Progress Images:

This image shows how we initially made the circuitry outside the box. A larger breadboard was used for clarification, and we later switched to a smaller breadboard so it would fit in the body box.

This image shows how each resistor was soldered onto the male jack. The legs of the resistors were bent so the sleeve would still fit onto the jack, hiding the different resistors inside

This image shows our final circuitry displayed outside the box. A battery pack is used for powering the Arduino, and the male jack part is sticking out of the box, representing Mike’s tail.

Discussion for progress and outcome:

The surprise Project was a bit tricky, because we first had to discuss and consider what the elements of surprise consist them. We focused on unexpected stimuli or the breaking of an expected pattern, as the source of the surprise we would utilize. We wanted to consider which parts could cause a sensation of surprise, and a sound producing element seemed to be the best way to do so. As far as outward design goes, the goal was something endearing, and easy to trust. Initially, the use of a face that produces noise was considered, but then we fiddled with a box, and we that a 3-dimensional entity would be far more interesting. This design leap was essentially the most difficult part of the project, because our technical design and creativity was limited by creation of parts which would operate with a face, while remaining user friendly. Becoming comfortable with accessing a variety of different items in the IDEATE workspace was an important part of our progress; we initially stagnated because we did not have the confidence to go forward from schematics. Moving forward, sharper, and more detail oriented design is an important area for future improvement.
