June 25 2006 - Test results link

March 27th 2006 - Updated video (Low Res.)of the direct hall test, indirect hall test (Low Res.), and around the corner hall test.

February 24th 2006 - All of these tests were run in the 3rd floor hall of Engineering I at UCSB. There are three tests with video. 1) At roughly 30 meters with speaker facing the reciever board. ( Video ) 2) At roughly 15 meters but the speaker faces the opposite direction of reciever. ( Video ) 3) The speaker is around the corner and out of direct line of site of the reciever. ( Video ) Note: It may be difficult to view the recieved packets on the screen of the first two videos so we will post a list of the recieved packets early next week.

February 22nd 2006 - This video shows an in air test where the transmitter and reciever are TI 6713 boards. This test was done in lab with about a 10 meter seperation. The first part of the video shows the test set up and the beginning of the test. The last section of the video is a direct screen capture of the reciever printing the recieved packets, on the right, while matlab shows on the left the sent packets.

February 22nd 2006 - This video shows a wire test where the transmitter and reciever are TI 6713 boards. The first part of the video shows the test set up and the beginning of the test. The last section of the video is a direct screen capture of the reciever printing the recieved packets, on the right, while matlab shows on the left the sent packets.

February 21st 2006 - Here is a screen capture of a wire test. The sound card is transmitting a signal generated by matlab and the board is decoding the received signal.

February 5th 2006- The group tested a board to board wire test today. Tricia and Daniel reworked the reciever board software to use a reliable timing aquisition and successfully implemented the software for the transmitter board. Video will be posted later this week.

November 28th 2005 - The group has now completed a proof of concept wire to wire test. A crude video shows the results of the test. Further videos and experiment details will be posted shortly.

January 10th 2006 - Daniel has estimated the battery life of the first deployed lifetime estimates based on a battery pack with 750 kJ of total energy and an average data
