Alan, Colin, Tom, Maduna, Tom, Bryan, Jeff, Charlie

Alex did the mojo and we now have DBI/DBD on the pmp. Next is finish transactions and cleanup code.
Jeff emailed ARM about the watchdog timer, no word yet. Charlie will look at the BIOS setting.
Colin will look into how to do damping of the direction and speed readimg.
Colin will fix the graphs including the date ranges.
Breadboard Wed at 1p
Rainguage is working and recording data, congrats Tom and Maduna. Mounting, reseting discipline and technique, and display elements are all that's left.
Windchill calculation, both the Davis interface firmware upgrade and the new formula. Bryan.
X10 systems. Tom waded into this and found some stuff. Heyu. Alan will get a serial controller.
Use WECI tower for annenometer mountings.
GPS.

Alan, Jeff, Bryan, Colin, Maduna, Tom, Alex, Charlie

C to read raw value, Perl (called from cron) to buffer to file and send to server every N times, server inserts into database and returns ACK to Perl.
Use TV antenna for the tower.
Check the TS-5600 library.
Watchdog timer (Jeff)
Rain gauge (Tom, Maduna)
GPS (Alex, Jeff), solar radiation (Colin, Maduna)
Alan's applications - 1) small machine that does temp and displays via http and send X10 commands out the serial interface with X10 switches and dial-up and ethernet interfaces. 2) robot to go in a house under remote control, B/W (or color) video, up stairs, 30 minute, budget of about $2000.

Tom, Colin, Alex, Maduna, Jeff, Bryan, Alan, Charlie

Do we have a calibration/accuracy problem WRT wind direction? Rest of the stuff listed below (Colin, Alex, Bryan)
GPS (Alex and Jeff)
Watchdog timer (Jeff)
Rain gauge, try plugging into the interface and testing (Maduna, Tom)

Colin, Alex, Tom, Jeff, Bryan, Maduna, Alan, Charlie

Laid-out the architecture of the quark-pmp-wind components and the interfaces.
Look at the TS-5600 library interface for reading ports rather than /dev/...
Put together a circuit based on a voltage regulator supplied by the board power port.

Alex, Bryan, Colin, Tom, Maduna, Jeff, Charlie

Regular meetings this semester will be on Monday at 12p in the Dennis 4th lab.
Wind speed and direction - data aquisition/data transfer/packaging/deployment (Colin, Jeff, Alex, Bryan)
GPS - data aquisition/data transfer/packaging/deployment/ntpd/clients (Alex, Jeff)
Rain gauge - data aquistion/data transfer/visualization (Tom, Maduna)
Solar radiation - data aquistion/data transfer (Colin, Maduna)

Fix wind chill calculation, use new formula
Figure-out watchdog timer on PMP
Backup on PMP - just needs to be put in cron (Tom)
Wind data for this area (Mary)
Problems with direction - determine input voltage and calibrate to that (Alex and Colin)
- Stable voltage needed, e.g. when WiFi card is removed voltage fluctuates. Measure at start and end, if equal than ok.
Porting wind speed and direction software and setup to pmp, made some progress (Mary, Alex, Colin)
- Speed working now, using sigalarm(), need a resistor? DIO for power.
- Direction isn't working yet.
- Next week on roof?
- Two weeks in field?
Sleep and wake on pmp1 with watchdog timer (Mary)
Weather Cam is working again, cluster camera to be setup in D209.
RP&L Weather data, contact Gus Duke. Indiana American Water has a link which she sent. (Mary, Charlie)
Rain guage, Mary has worked on it but it's not working. (Mary, Charlie)
Solar radiation sensor, continues to make progress, conversion and data comparison (Colin)
- How to set angle/calibration.
GPS setup with time server (Tom)
