Auto-dialer

• Difficult to find an off-the-shelf, ready-to-use
  auto-dialer
• Most products have integrated auto-dialer
• Instead, with sponsors permission, we used a
  modified auto-dialer and keypad

Xilinx Programmable Logic Device vs. Basic Atom

• Xilinx
• Cost
• 49.95 Programming kit
• 5.78 /ea. Bulk order (100)
• Integrated Oscillator Timing
• No need to order addition chips
• Basic Atom PICmicro
• Cost
• 139.95 programming kit
• 59.95 chip 15 I/O pins
• ATOM Limited to 15 I/O pins
• PIC 3.99 5.04 Volume order

Programming in VHDL for the CPLD

• Compared to C/C
• Helpful in learning
• Statements executed concurrently
• What we needed to use
• Time conversion
• Voltage drop
• Help with debugging
• Good tutorials

Mass Production

• Use company to produce logic board
• www.em.avnet.com
• 256 flip-flops 100 12.38 per (150)
• 128 flip-flops 100 5.78 per
• 64 flip-flops 100 2.53 per
• Create own auto-dialer and integrate into logic
  board

Conclusions Recommendations

• Prepare for mass production
• Rid program of debug modes to optimize program
  for production. Leads to cheaper and smaller
  electronics.
• Mass produce electronics on smaller logic boards
  without unnecessary components
• Look at methods such as injection molding for the
  packaging
• Can easily add a smoke alarm/carbon monoxide
  detector to system
• Smaller IR sensor calibration time (30sec)
• Reduce to one battery pack
• Would need to rid electronics of debugging LEDs
  and programming to use less power
• Build auto-dialer circuit from scratch integrate
  with other electronics
