Any engineering major at any engineering school in the US must take a course entitled Introduction to Engineering Design (IED), or something similar. Right now, I am teaching that course at a local college. I think it would be useful for students to have a thread in which information on various IED projects can be posted. To keep things nice and organized, I am going to ask that there be only one post for each type of project. If you find info on a project that has been posted and think your info should appear here, then please PM the author of that post and ask him/her to edit it in.
