Abstract

• General purpose power strip design
• Consumer use
• Reduce power consumption
• Entertainment
• Security
• Automation

3
Device Concept

• Physical component supplying 120v AC
• Modular interface
• Controller (eg PC)

4
3 Phase Design

1. Physical Construction
2. Software Implementation
3. Standalone/Remote Interface and Further
   Application

5
Phase1 Physical Construction

• 5v Logic
• LED Status
• Connection to interface module
• Control side of relays
• 22 gauge wiring etc
• 5v DC power supply

6
Output Device Circuit

• Relays (AC, DC, stepper) the core of the device
• Power switch (only effects 120v circuit)
• Power sockets
• 16 gauge wiring
• Power supply cable

7
Safety

• Human
• Plexiglas shielding
• Hot 120v wiring centered
• Standard home-grade power sockets
• Power switch
• Equipment
• Hex inverter/optoisolators to isolate interface
• Fuse to isolate building power circuit

Phase2 Software Implementation

• Multiple OS (Windows/Linux)
• Localhost
• Web Interface
• Lights synchronized to music

10
Localhost

• Simple
• Required for later implementation
• C program to toggle individual sockets on and off
• Linux simpler because provides direct control

11
Remote Control

• Computer directly connected to interface module
  hosts Webserver
• PHP/Ajax gt Apache gt localhost application gt
  drivers gt device
• Can use wireless / PDA

12
Winamp Entertainment

Phase3 Standalone / Further Dev

• Onchip server for ethernet connection
• Further Study
• Vision control
• Remote music
• Scripting and automation
• Scalability
• Further software development
