Actual Project

How it Works

Electronics
Wi-Fi Router
Charge Controller
Power Meter
Batteries
VOIP

Charge Controller
Prevents the batteries from over charging
Once the voltage across the batteries hits a set level (13.7v), power is sent to a set of power resistors until the voltage drops

Power Meter
Monitors current flow to batteries and sends data to a remote server

Power Meter
Web Site makes it easy to view power data
Website
Server Code

Wireless
Utilizes Wi-Fi Based Equipment
Inexpensive
High Performance
Uses two Linksys WRT54G Wi-Fi Routers
Uses DDWRT Firmware for more flexibility
One in AP Mode with 8dBi Panel Antenna
One in Repeater Mode with 19dBi Parabolic Antenna
¼ Mile Link

VOIP
Enables Free Voice Calling
Allows the communication node to become a wireless phone booth
Utilizes Google Voice for free incoming calls
VOIP Server
VOIP to Analog
Phone Adapter

Innovative Applications
Third World Rural Locations
Extend Internet connectivity from urban areas to rural areas
Connect villages together

National Parks
Provides up-to-date weather and trail information
Many parks do not provide reliable cell phone coverage
Hiking fatalities can be prevented by alerting hikers of potential trail and weather danger

Disaster Recovery
Quickly deployable and inexpensive communications network
Self sustainable –> no need for diesel generators or any other infrastructure that could have been destroyed

Team Work
Key to Project’s Success
Dan is very knowledgeable of wireless communications and networking
Dave is knowledgeable of embedded and high-level programming for the microcontroller and server
Worked together extensively to solve the mechanical and electrical aspects of the project
