    We need an arduino shield that can communicate with z-wave.The following example:http://www.elechouse.com/elechouse/index.php?main_page=product_info&cPath=90_92&products_id=2169Does not speak zwave protocol. We need to communicate withthe z-wave devices in the home-centers, for example:http://www.amazon.com/GE-45604-Technology-Outdoor-Lighting/dp/B0013V8K3O/ref=sr_1_1?ie=UTF8&qid=1363603294&sr=8-1&keywords=45604This is one-way communication of simple on-off commands.Please do not exceed the max price. You will be responsible for all materials you need for prototypingthe board and testing the device. You will deliver a working prototype with PCB designs, schematics,and software. You must be able to control the 45604.

    Networking Cape for BeagleBone BlackDesign a Data Communication/ Networking Cape for BeagleBone Black with ‘8’ RS232/ RS422/ RS485 D-Sub9 ports with full signals.Beahlglebone comes with one or two RS232 port. We need to develop an interface through which we can simultaneously connect 8 devices via serial interfaces RS232/422/485. We need to probably use the UART signals available with beagle bone and maybe multiplex them. Also we need to develop the firmware for the same..We want to learn how to design the circuit, develop it, create firmware/ drivers for Linux and adequate testing of the same.
