Overview
 Frisbee wirelessly communicates
with wristbands to track
gameplay and player statistics
for the game Ultimate Frisbee



Team scores
Player throw/catch count
Out-bounds & end zone detection
Block Diagrams
Calculations
 Frii’s Equation can be used to determine
the power levels received at varying
distances
𝑃𝑡 𝐺𝑡 𝐺𝑟 λ2
𝑃𝑟 =
4𝜋𝑅 2
𝑃𝑟 = power received
𝑃𝑡 = power transmitted
𝐺𝑡 = 𝐺𝑟 =
32
sin 𝜃 3
3𝜋
= directional antenna gain
λ = 0.3960 m at 757.5 MHz = quarter wavelength
R = 10in - 60in (.254m-1.524m) = antenna distance
Received Power(dBm) vs Distance(m)
Simulation Results
Prototyping and Assembly
GPS and Battery Testing

Conclusion
 Project Outcome: TBD
 Future Work:




Smart Frisbee serves as a proof-of-concept
Modify the Frisbee as little as possible
Redesign as consumer product
Optimize for mass production
