In prep for a post-mortem on this project, I wanted to start a page of issues that have occurred:
| Issue | Action Taken | Future Actions |
|---|---|---|
| USB sticks died (all? were purple 8G Transcend) | Switched to Pocketec, Compact Flash, New stick | Replace all sticks with new ones recently purchased |
| GPS timing odd | Widened range of acceptable time lag | Upgrade software on all receivers (3.0-3.7 -> 3.9) |
| 200m DSM needed 150m GPS, but it died | Changed to use 250m? GPS | None? |
| Qsoil reading 0x8000 | none | Fix Check connector at tear-down |
| CSAT3 broken upon installation | Repaired at CSI – bad coax cable in head/box | Unknown - new handling procedure? |
| XBee mote not reliable over 3m distance | Changed to serial mote (tried changing power) | Change to all Bluetooth motes? |
| TRH went to large values | eio power cycle | Unknown |
| TRH fan controller died | Replaced | Check; see if systematic issue for all |
| TRH sensor died | None yet | Improve rain vulnerability? Lightning issue? |
| Lost data connection when eol-rt-data changed | eol-rt-data configuration restored crontab script fixed | SIG checks with Gordon (he tells them when using?) SIG avoids "snapshots" |
| Odd Gsoil at ehs | none | Don't install in darkhorse shadow! |
| EC150 bad data for a week | Cleaned bird scat | Install bird diverters? |
| tsoil.bao mote data intermittent | none; came back | Unknown |
| Mast issues: guy wires; winch; clamp positions; tight nubs | Various in-field adjustments | Systematically check each component for all masts |
| AC powering failed (probably loose connections) | Changed to solar power | Test this option (needed in future) |
| Picklefork Tsoil died (then revived!) | none (had installed duplicate picklefork) | New picklefork design |
| Picklefork completely died (bao) | none | Diagnose Create new picklefork probe (in process) |
| EC150 data garbled on ttyS4 at bao, OK on ttyS4 at ehs | Moved to Emerald serial port on bao | Diagnose. Seems to be a rs422 signal level or termination problem |
| 150m DSM didn't come up after power drop | Manually switched off/on | ?? |
| 250m? DSM USB stick died | Changed to Compact Flash | New USB sticks purchased |
| Mote communications failed on bao Tsoil | Enabled XBee watchdog | Change to Bluetooth Enable all watchdogs New whip antenna location? (birds/wind knock down) |
| New Tirga fan died | Replaced | Better rain protection? |
| New Tirga has radiation error | Installed double-shield | Might be acceptable now |
