Class 11

In-Class Activity

Since last week, you’ve learned about motors and high current loads. We’ll discuss the following, and answer any questions that came up.

  • Review from the assigned readings and labs: 
    • Controlling High-Current Loads
    • Current and energy
    • DC Motors and Stepper Motors

We’ll also talk some more about project planning and documents that are useful in making a project:

  • Project descriptions: how to describe your project for execution. How this differs from describing it conceptually
  • Drawings for project planning:
    • system diagrams
    • floor plans
    • elevations
  • Timelines
  • Bills of materials

Assignments For Next Class

By now you should have an understanding of physical interaction from assignments and class discussion. Your final project should demonstrate your understanding of these ideas, and the electronics and communication techniques needed to build devices.

To get a sense of what might be possible, review the labs, especially those which weren’t assigned in class or which you didn’t complete, for ideas for how to execute your idea.

Project 3

Come up with an application of the ideas and techniques you have learned in this class. For some ideas on what you can make, see the Assignments page, Project 3. You can refine one of your previous projects or come up with a new project.It’s due in week 14.

Blog your idea for next week and come up with a prototype for playtesting.

Like the previous projects, this shouldn’t be a highly polished device, but give it a housing of some sort. You could make something task-oriented, like a special-purpose mouse controller for a personal computer, or it could be very expressive, like a game or toy. The focus here, as with the other two projects, is to make a device that a person understands how to interact with, and can achieve the goal for which the device was made.
