Thanks to Scott, Brent, Roman, and Cheri for the long hours last night bringing Neo and Mack back to life...
Deployment Update
- MOB Tuesday PM, depart Weds morning 06:30. Crew will be Chris S., Roman, Scott, divers: Lonny & Mike. Crane operator Luis, with x-tra pay for childcare/OT.
- Will deploy one @ MO, travel to SC, then back to M0 (allows 1 hr b/w each dive for divers)
- In water will fire off full-phase. Then rest and start on 11th.
- Moorings: lots of little things still to do, but coming along nicely.
The Plan:
-
- Mack and Bruce will be canned tomorrow (Friday). Bruce will be moved to it's mooring in preparation for radio testing.
- Brent will radio test Mack Friday.
- Saturday, Chris P will load PCR reagents on Neo. Then start a 24hr run lat Sat, making sure to do a full MFB with BAC run. This will confirm all reagents are good. At start of this run will note power on Watts-up meter so we can get a power usage estimate for a full run.
- Neo gets canned Monday
- Dual radio testing for Neo/Bruce Monday.
Machine Builds
- Dwarf Boards:
- Dick soon to go on 2 wk vacation
- All boards tested. 6 R-valves fail. Failures came on motor tests. Could be Xylinx solder joints.
- Wayne writing a 'theory of operation' for dwarf and R-valve boards
- Issues with cores:
- Mack: replaced a dwarf board yesterday when it was acting unreliable. First board to go bad in long while.
- NEO: Brent fixed jittery Sample syringe brought about by too slow a minimum speed for integrator to adjust to. This change may need to be carried to all cores.
-
- Brent noticed hand could not extend all the way. May be a calibration/config issue; will work with Scott on this
- Software: issue with getting emails outside our firewall; Brent chewing on a fix for this.
- Chris wants to run short IPC and SAR 11 to see if column is working. After that, run some negatives to show it's clean. then fire off a full SHA.
MFB
- Grill progress stalled until Mike gets freed up. Addie asked to put in formal requests for work to get into que.
- New MFB user's manual will be on Confluence Friday or Monday.
- New LLNL module not tested; waiting on SPE heater block from Mike
Software
- New CTD's have different firmware. Nontrivial.
- CS syringe on NEO has been changed
- Bruce--got stuck last night. Anytime tried to move a syringe or valve it hangs. It waits for a thread that's already dead.
- Mack--PS and clamp got corrupted (overcurrent errors). Sent out a 'recover' and it fixed it.
- Can't seem to FTP into shore station from his house
- Radio tests worked well, but while one file is uploading, link is monopolized (we can't talk to the other machines)
- Will give radio's to Jose
- Home syringe has been renamed.
- Firmware code still not frozen until Brent fixes: 1. Recover from hang due to dead thread, 2. Link protocols fixed, 3. CTD changes made
DWSM
- Sphere bottom (2nd casting) is finished w/ rough out; needs finish work and ports milled
- Sphere top (1st casting) won't make shape, but machining adjustments will make it acceptable (or we'll de-rate it)
- Should be finished in 2-4 weeks
- Bulk-heads (swiss cheese plates) are in the mill and being processed.
- Doug soon to deliver large PO for Pressure transfer barrier (accumulator) for $6K
Elevator ideas:
-
- will have roughly 6'x6'x8' size. Lobos crew thinks size will be fine
- Doug believes 4 leg will be more stable than 3
- Foam pack findings:
- 40lb/ft^3 will be $16K; 28lb/ft^3 will be $20K; Glass spheres will be $10K but much risk
- will go with 28lb/ft^3; they say ~January delivery. Buying in brick format so useful for others after ESP project ends.
- Much brainstorming about elevator design, working at angles, how to counteract uneven surfaces, etc.
GUI Development
- Kevin working with Chris Preston on the new 'killer' mission planning app; Chris having trouble running on her home machine
- data management software should be finished tomorrow.
Other Items:
- Doug provided a 2009 deployment breakdown. Chris, Jim, Doug will discuss off-line before approaching Grech about schedule.
