Gantt Chart
4
Tasks Performed

• Finished Python tutorial (Eldridge)
• Finished accelerometer test board (Kristi)
• Designed cell phone user interface for GIZMO
  truck (Eldridge)
• Worked on final circuit board design for GIZMO
  truck (Kristi)

5
PCB Design

• Made custom device libraries for bluetooth module
  ATmega164p
• Through-hole components gt mostly routed on the
  back (blue traces)
• Also reduces problems due to no through hole
  plating
• Stacked bluetooth module microcontroller to
  save space
• Uses modular accelerometer board
• External clock source

6
Python for S60

• Write Python applications for cell phones with
  S60 platform

• About S60 Platform
• - Allows software on cell phones to run
• - Provides full-color user interface
• - Includes software to combine features of a
  mobile phone and PDA
• - Examples e-mailing, browsing, calendar,
  data transfer

Python for S60 (cont.)

• Advantages of Python
• - open source
• - object oriented
• - extensive standard library
• - modules can be extended using C or C
• - applications can be written quickly
• Additional Advantages of PyS60
• - can create standalone applications
• - additional modules to access cell phone
  functions like camera, audio, and Bluetooth
  communications
