2. Ethical Concerns  Harsh temperature conditions  Atom board rated for 0-60 C  Purchase more rugged version of board  Harsh physical conditions (bumpy terrain etc)  External cable connections and internal PCB connections could become loose  Make system a more “integrated” part of the golf cart to reduce number of cable connection points  SD card system reliability  System “guesses” that there is no SD card in slot when initialization fails. (No way to differentiate no SD card and bad SD card)  Utilize card detect pin to tell if there is a card inserted

3. Ethical Concerns (cont’d)  System fails to warn user of dangerous conditions  User would not know to take reactionary measures  Use mechanical fail-safes (e.g. pressure valve)

4. Environmental Issues  Project is unnecessarily wasteful from a materials standpoint  PCB is larger than it needs to be  Could maybe even do without a PCB at all and just use Atom board  Extra 36V lead acid battery needed due to change in research project plans  Decisions made implementation simpler and made project suitable for ECE477  For mass-manufacture, just use Atom board with SD card reader with a tiny PCB  Tiny PCB will just contain 12-5V regulator and some ATD chips
