Team Watts in the Box Presents… TeslaBox. Stephen Bennett Devin Callahan Ben Kaslon Sushia Rahimizadeh Connor Shapiro . Project Proposal and Purpose Hardware Design and Implementation Level 1 and 2 Block Diagrams Software Design and Implementation Use Case, System Context Diagram
This project will consist of a scalable box or drawer in which small hand-held devices or toys can be placed and wirelessly charged.
The box will require only an external source of power in order to be able to charge the devices.
The devices will perform all RF harvesting and charging automatically without user input.
The user simply opens the lid, places the devices inside, and shuts the lid. The devices do the rest.
The purpose of this project is to demonstrate the feasibility of scalable, commercially viable wireless charging.

Most required components can be purchased directly from electronics suppliers, including:
Devin CallahanEconomic Viability
Main concern of the system is to ensure minimum leak of RF power in compliance with FCC regulations
It will be easy to see if this project is working or not. Either the battery on the device will be charged or it will not
Component tolerances will not affect the design, apart from negligible detractions from system efficiency
This system exhibits zero risk to the environment or the population so long as all RF energy is kept within the box
A standard 120VAC outlet plug will eventually be used
