Project modules Ipaq Module –Using Smart Remote Controller Project by Pavel Vilk and Piotr Drubetskoy PC Module –Using Access Point simulator on CAN2USB from HWC Project by Ehud Ravitz and Lee Blum

Smart Remote Controller Project by Pavel Vilk and Piotr Drubetskoy Implementation of a system which includes a single Remote Controller capable of controlling several devices in different rooms via Access Points, connected via LAN. The Remote Controller and the Access Point are implemented on a PDA with a Blue Tooth link and CE OS. The Access Point manages a piconet of devices implemented as black boxes on a PC.

HWC Project by Ehud Ravitz and Lee Blum Aim of the project Create a cheap wireless control network on household appliances. –Create Bluetooth connection between an Access point and an End Point. –Create CAN connection between two Access Points.

Technologies Ipaq Bluetooth Stack –Ipaq 3870 has no free Bluetooth stack development kit. –Upgrading to Windows Mobile 2003 adds a native Microsoft BT stack that is not supported by the OS. ZigBee –Expensive development kit –Low Power –Small transfer rate

What have been done so far? Learning to work with the MPLab and the PIC Development Kit Learning the Bluetooth Protocol Learning the CAN Protocol System and application design Learning to operate Home Wireless Control project

Schedule – Finish employing HWC project – Build the IPAQ controller – Build the PC controller – Final report and presentation
