1. R.O.M. System Team: RISC Takers Team Members: Paul Banks, Yorick Robinson, Evan Tu, & Hans Weggeman Louisiana State University – Senior Design October 29, 2013

2. Database upgrades have been made Raspberry Pi has been loaded with the software in order to boot up and wait for remote inputs Implemented log in page and switches to interface with GPIO pins The PCB for the Power Supply and Switching Component have been designed and will be fabricated this Thursday. Work Performed to Date

3. The code for the MSP430 switching circuit and power reading is complete with the ability to wait for a signal from the Raspberry Pi Simulations of the Power Supply and Switching component have been performed. Work Performed to Date (Contd.)

4. Database

9. iOS App

11. Power

12. Power Supply Schematic/ PCB Design

13. Power Supply with Switching Component PCB

14. Challenges and Changes Instead of a Shunt Resistor, a Hall-Effect current sensor will be used for circuit isolation. Smaller PCB Design using different Transformerless supply schematic. X-bee modules have had interfacing issues For more efficient data storage within the application, we have made the change from an archiving technique to using Core Data Testing has revealed bugs in the iOS data model. The problem is known, but we have yet to find the solution

15. What’s Left Connecting iOS application to interface with the Raspberry Pi database Interfacing with X-bee between hardware and software Printing out the current sensing and switching circuits Connect these PCB boards to the MSP430, Xbee and Hall- effect Sensor. Testing synchronization between database and web- connected devices Testing all elements within the system working together

16. What’s Left Output from the Hall-Effect Sensor must be adjusted to be compatible with MSP430 All PCB’s must be soldered and arranged for most compact design Housing for the Plug-In’s must be designed and fabricated after PCB arrangements have been decided.

17. Gantt Chart

18. Final Presentation Two separate wall Plug-Ins will be set up with devices connected Main Hub will be self starting and set up with an Ad-Hoc router An iOS device along with laptop will demonstrate home automation capabilities along with power monitoring Being able to demonstrate the convenience of scheduling devices and logically pairing them
