___________________________12Lessons from the group membersDan:

My best lesson learned is to design all systems for testability.

We always gave and accepted honest and critical feedback between ourselves on design decisions, never fighting because we recognized that open and honest communication would build trust in the group and result in a better overall product.

Jack

More planning also should have been given to acquiring proper tools for metal working, especially a drill press

Lukas:

Arduino microcontroller: it turned out to be a great development tool especially with its open source platform, multiple analog and digital pins, serial communication, and headers for attaching custom made prototyping boards.

I learned to always ask if I didnt understand something and that making mistakes are essential to any learning experience.

Mike

I have seen a few 440 demos and was always disappointed. It seems that students work for hundreds of hours on their projects and then demo in a room with a couple friends, the instructors and a closed door. It seemed depressing to me that you can spend 5 years of your life in an engineering program, and no one cares what you have accomplished at the end of it.

Take a break. Go out for dinner, go to a movie, have a beer, have a pop, take a walk, take a hike, and ski back down. Project courses can steal your life. Steal a few hours back.
