==== Projects ====
  * [[atmos:3d-paws:VisibilitySensor|Visibility Sensor]]

==== Current Stations ====
  *[[atmos:3d-paws:und00100|UND 00100]]
  *[[atmos:3d-paws:und00200|UND 00200]]
  *[[atmos:3d-paws:und00300|UND 00300]]
  *[[atmos:3d-paws:und00400|UND 00400]]

==== Hardware 3D-PAWS ====
  * There is no drop ceiling clamp available.
  * Sensor Sub-Assembly 4 is confusing, Need to put male jumper on female to make male-to-male.
  * The small square magnetic comes with the sensor.
  * Current printer filament: Overture PLA 1.75mm
  * Current Printer: [[atmos:3dprinter:Huafast HS]]
  * Current Printer Location: Clifford 601
  * Current slicer: Ultimaker Cura


==== Software - SD Cards ====
  * Command to write image to SD card on Linux, where /dev/mmcblk0 is the device of the card on the system.
    * sudo dd if=./3dpaws_pi.img of=/dev/mmcblk0
  * Command to read image SD card on Linux, where /dev/mmcblk0 is the device of the card on the system.
    * sudo dd if=/dev/mmcblk0 of=./3dpaws_pi.img
  * Label the SD Cards with Current Station serial number and software date
    * Example: UND# # # # # & YYYYMMDD (no spaces between #'s)

==== Software - Rassberry Pi Configuration ====
  * Within terminal navigate to find Host Name
    * cd /etc
    * sudo vi hostname
    * Host name will be 3D-PAWS serial number and software date
      * Example: UND# # # # #-YYYYMMDD (no spaces between #'s)
    * To save enter ->  :w
    * Then hit enter and save as usual
  * Navigate to Hosts to set the IP address 
    * cd /etc
    * sudo vi hosts
    * Hosts is localhost IP address
  * Communicate with 3D-PAWS by installing TeamViewer software
    * Rename "Your Display Name"
      * Name will be:  UND# # # # #-YYYYMMDD
    * Assign to Account: for now we are using David Delene's account
    * Security
      * Change Password to our standard password: sudo su; passwd pi 
    * ID Number: enter into GoogleDocs

==== Software - Raspberry Pi Setup ====
  * To setup/change software for new stations:
    * On the Desktop, click the 3D-PAWS icon
    * Settings
    * CHORDS menu 
    * Set 3D-PAWS ID to the correct number
      * Found on CHORDS site
    * Set web address
      * Replace 3d.chordsrt.com with CHORDS IP address 
        * Example: #.# #.# #.# #.com (no spaces between #'s)

==== Current Problems and Possible Solutions ====
| High winds on roof blow over rain gauge        | cement PVC fitting connection in place, more leg supports? |
| Internet connectivity                          | Run a Ethernet cable out from room 601 to roof             |
