Meeting Notes 2011-10-14
Team members present: everybody
MCU: have all the calculations; get it checked out by a professor (Dr. Bowman, Dr. Amuso, Dr. Becker-Gomez, Dr. Patru?, etc.)
I/O signals: Change ETA to be given on a button press. Use a lockout for input. Make sure the testing information filters down to how the signals are given to the user.
Vibrational motors: avoid the situation where the motors interact to the extent that the device becomes a cell phone; consider damping. The Mitsumi meeting was really helpful for thinking about component choices. Think about how the device functions on a human level, not just an engineering level. Focus on ergonomics as well. Jeff located a testing scheme that was used by another university for research into touch detection/resolution on skin and adapted it to vibration. Make motor choice ASAP. Order multiple makes of motors if necessary. Leaning towards coin motors.
Heat transfer: Numbers seem unusually good (low air temperature given the housing wall material/thickness). Get a second opinion - Dr. Schrlau?
Accelerometer/magnetometer combo component chosen.
Before next week
- heat calculations / CAD drawings
- Update the risk assessment
- Get access to the EE senior design labs
Before next meeting
Jeff, Curt, Magy: testing
Aalyia: finalize keypad and work on I/O signals
Stu: follow up with Dr. Stevens & add battery
Oliver: finalize MCU and start algorithm
Dave: schematics for all the circuitry
Bill of Materials
Move the Google Docs list to EDGE for easier version control / grading access ;)
