3
History

• In 1964 the first ball was made from telephone
  parts.
• National Beep Baseball Association (NBBA)
• The ball gets redesigned

4
How To Play

• Played on normal baseball field
• Two bases first and third
• Randomly buzz on hit
• Scoring
• Reaching the base before the ball is fielded.

5
Product Goals

• Design Safety
• Wireless Controller
• Eliminate long wire runs
• Compact shipping size
• Shipping to Asia costs over 1000
• Reduce cost
• Current base costs 500

6
Design Specifications (package)

• 1. Small shipment size.

• 2. Can take grown men running it over and can
  stay standing in 30 mph winds.

7
Future Improvements

• Column shaped base
• -Thinner PVC coated fabric
• -Airtight Fabrication

• Pyramid shaped base
• - More Protection

8
Design Specifications (Acoustics)

• Steady frequency
• Wired sound could be lost if unplugged
• Unidirectional

9
Our Updated Sound

• Omni directional
• Varying sound
• Stable throughout impact
• Programmable

10
Future Sound Updates

• Add buzzers to increase sound
• Make user variable
• More distinguishable
• Integrate into main board
• Stronger
• More expensive

Room for Improvement

• Incorporate solar panels into base design
• - Eliminate batteries
• - Self-sufficient
• Hot user selectable acoustic frequencies
• - No programming required
• Statistic tracking options
• - 1st or 3rd base?
• - Did the ball make it to the outfield?
• Incorporate prognostics
• - Use accelerometer to detect impact force
  (assuming pre-determined mass of runner assigned
  by remote control operator)
