Status Page:
* 6/7/04 - Bought some groceries, entered their product
information in the db, and affixed RFID tags. Also fixed scanning the
mode tag so that it does not loop through the modes too quickly.
* 6/6/04 - Rewrote the price parsing routines to better communcate the
price. Obtained additional samples to do so. Got the system working as
a standalone unit, disconnected from daughter-board and any network
connectivity.
* 6/5/04 - Obtained new sound samples from a text-to-speech engine on
the ATT Research site. Added a mode button to allow a user to toggle
between the information that is played: All, Name-only, Price-only
* 6/3/04 - The glove is apparently dead, and we will not get a new one.
We will use our other reader to simulate a glove, and perhaps gets a
glove on loan from Intel if a video is made.
* 6/1/04 - Obtained a new personal server, loaded the
software, and the system is back up.
* 5/31/04 - Didn't get anywhere tonight, but took considerable steps
backwards: 1) cannot get the personal server to boot, hopefully a
transient problem 2) the small board assosciated with our rfid-reader
glove seems to be having problems; Saurav thinks it might need to be
replaced.
* 5/29/04 - Working on building the glove. The glove with a mylar
attenna does not seem to work very well, or our system is not built
properly. Wrote the logic into our scanning service to get various bits
of information from the database to play the price, brand, sale, etc.
for a product when it's rfid tag is scanned.
* 5/28/04 - Fixed the problem calling the audio program. Configured the
jre to use an older version of libc with the functions it needed to run
properly. System is now working from end-to-end, scanning ids, then
playing the proper audio clip.
* 5/27/04 - Troubleshooting the problem calling the audio player.
Appears to be an issue with blackdown's jdk release that relies on an
old version of libc. Tried a different jdk release for the arm, but
that was a dead end.
* 5/25/04 - Service is working to the point where it will take rfid tag
scans, look them up in the database, then launch the program to play
the proper audio clip assosciated with the rfid. Ran into a issue where
the runtime call to our audio player is hanging, an error about the
libc settings.
* 5/24/04 - Wrote most of the SQL code for the more finalized product
database, which includes 5 or 6 tables. Recorded ~200 wav files to
accompany product data. Tested performing various queries against the
db from the command line.
* 5/23/04 - Went to a local Safeway and scouted out product
arrangements, organization, and store layout. Recorded information on
several products and designed the layout for what our product database
will look like.
* 5/20/04 - 24:00 - Update and brochure finished. Got CF mote working.
Got slappy board drivers loaded and audio output. Developed a simple
process to listen for RFID scans and query database based on received
ID. Works on dev PC, but not with jni drivers on personal server. Also
got a RFID scanner sautered up, and anticipate getting the glove soon.
* 5/19/04 - 23:00 - Saurav is still working on Update 2. Found out from
Waylon that all the parts for the glove have arrived but the antenna is
still being calibrated at IRS.
* 5/18/04 - 23:00 - Working on both Update 2 and product brochure (no
substantive work on project); found out from Waylon that we will need
to wait for glove antenna to arrive, and for him to get the glove parts
from Intel lab
* 5/17/04 - 23:00 - finished java client to the C serial forwarder;
installed MP3 software on personal server, and started looking into
drivers for the slappy board
* 5/14/04 - 12:00 - gathered some jdbc code together for talking to
sqlite database from our java service
* 5/13/04 - 17:15 - started writing the java code to talk
to serial forwarder (.c) program. This java program will also interface
with the database.
* 5/13/04 - 16:45 - met with Waylon, set up a time on Monday to make
the RFID glove. Also confirmed we will be using a mote on a compact
flash card, although according to Waylon that is uncharted territory
* 5/12/04 - 10:00 - worked on getting the asf.c program working, which
takes the serial data off the motes on the personal server and spits it
out to a network port.
* 5/10/04 - 20:00 - got radio transfer on TinyOS done, transferring
fake RFID reads.
* 5/5/04 - 17:00 - Presentation turned in. Saurav is working on TinyOS
tutorials for radio transfers.
* 5/4/04 - 24:00 - We both worked on the project presentation, majority
complete. Andrew finished the architecture diagram, Saurav will finish
the last page or two on expectations and evaluation.
* 5/3/04 - 23:00 - Preliminary presentation slides put together, last
few slides and a diagram still needed.
* 5/1/04 - 21:00 - Started on the project presentation for 5/5, culled
slides from Chuck's Industrial design presentation, adapted for our
project.
* 4/30/04 - 16:00 - Saurav worked with Waylon to resolve Cygwin issues
enabling him to work with TinyOS again. Our lab computer is fried
and we are waiting for a replacement after showing it to Bruce
Hemmingway. Waylon and Saurav worked on sorting out some key
issues about the RFID side of things.
* 4/30/04 - 11:00 - We met with Gaetano. Talked about the project
update.
* 4/29/04 - 23:00 - sqlite JDBC access drivers finished, Andrew
beginning work on Java test application.
* 4/29/04 - 21:00 - Saurav is investigating the JNI interface between
motes and Java programs, and also working on TinyOS. Andrew is still
setting up the database tools.
* 4/27/04 - 15:30 - Slappy board recieved.
* 4/26/04 - 23:30 - Update 1 completed. Andrew is installing
SQL-lite.
* 4/26/04 - 15:30 - Recieved TinyOS code for the RFID glove/base
station motes.
* 4/23/04 - 11:30 - Presentation slides from Chuck Ely recieved.
* 4/21/04 - 15:30 - Realized javac isn't and wasn't meant to be
included on the Personal Server.
* 4/20/04 - 13:00 - We tried installing MySQL and J2SE on the personal
server, but ran into problems with the environment. SSH is still
not set up for file transfer to the personal server, and there is not
enough space to store the J2SDK install files. Waylon reported
that the RFID glove may take some time to procure. Andrew will
try to work with Trevor to get the personal server ready. Saurav
will try to get the RFID glove from Waylon and work on the
presention. Saurav will also meet with Chuck Ely.
* 4/16/04 - 15:00 - Saurav has picked up a personal server, three
motes, and a mote programming board. Still waiting for a Slappy
board and the RFID glove.
* 4/15/04 - 07:30 - Andrew and I have finished our project proposal.
* 4/15/04 - 02:00 - Andrew and I worked on the project
proposal. It is 2:00 am and I will retire for the evening. -
