ESP Engineering Mtg -- Jan 31, 2008

11am-12
Present: Jim, Chris S., Kevin, Doug, Cheri, Brent, Scott, Addie

Tech Transfer

Discussion Items:
  • Results of hand/arm testing.  
    • Mack has been cold-tested and Brent is working on temp sensor testing.
    • Bruce--all valves are in, hand mostly assembled, still to finish plumbing
  • Mike Parker Machining list -- working quickly through it
  • New hand order.  Plans update?  Mike ready to go to El Camino?  How many?  N
    • New hands to be ordered this summer.  XX hand assemblies + 3 sets of fingers with new fulcrum positions to replace the existing 'new' fingers
  • New syringe cost. 
    • Still not heard back from company
  • New Dwarf Boards.  ~$4K/system with 6 week lead time.  Account?  How many? 
    • Jose still forming the database.  Just a core, but all electronics (no MFB),  Jose should charge 900612,  maybe a subaccount (.99 for CIP)).

Action Items

Action Items from last week:

ACTION: check with Jose about number of dwarves to order (Scott)  In progress:  Jose has mad the first pass through and looks like all components are still available.  Jose getting price and lead time on everything.

ACTION:  syringes.  Wait to hear from company final costs and order #'s and get sample of their new product. (Scott)  In progress 

ACTION:  Will cast a new schedule taking into account our current progress (Jim/Cheri/Scott)  Finished
ACTION:  Order fluidic fittings for cores and MFB (Cheri)  Finished
ACTION: Will drill out pressure sensor holes in clamps when we revalve the cores. (Scott/Cheri)  Finished

MFB

Discussion Items:

  • Getting excellent yields out of solid-phase-extraction--Good job Addie and Chris P!!
  • Mixing column basically finished
  • next week will make extract from seawater lysate and compare to bench-top
  • in parallel, do dye tests with heater block.

ACTION:  Hook up heater block and test diodes for fluorescence sensitivity. (Addie)  In progress
ACTION: Will work on figuring cable problem to three-way valves. (Addie) Finished
ACTION: Mike will bore out stator on the mixing column so we don't need more mix tubing or reducing fittings. (Addie) Finished
ACTION: Fan not working on PCR module and Addie will try and track down why (check in various terminal/call LLNL) bob said he's never had the fan turn on or off with that module. (Addie); Finished

Software

  • puck heating control
    • now can send a temperature to puck and it gets there in 2-3 minutes with little overshoot
  • Brent would like to pull calibration values out into a structure, since they are different on each instrument

Action Items: 

ACTION:  Finish by Feb 6 the temperature calibration model, incorporating Scott's prior work if possible. (Brent)
ACTION:  make another temperature puck (Scott)
ACTION:  Write 'cheat sheet' showing new parameter available for changing during sample collection (Brent)

Action Items from last week:

ACTION: Set-up sleepy board and an elmo on desk to emulate (Brent)  In progress: Can't find elmo but have other pieces.
ACTION:  working on a cue of interrupts in the threading environment (Brent): Low priority Not started
ACTION:  Work with the auto-cal code for carosal and aligment (Brent):  Medium priority Not started

Sphere and 4K DWSMS

  • Screen drawings. 

Battery boxes?  Scott still waiting to hear.

  • DWSM progress?   Have ~$1300 of parts coming into lab to build lung system.  Going into Bldg B lab.  pumps not coming in yet, but will find hand-pumps.  Will start construction next week.  Maybe need some days of Jim S.

ACTION:  Waiting for company to return yes/no on whether they can manufacture screens to mass instead of size. (Doug/Scott)  In progress
ACTION:  Order two battery boxes (w/out batteries)--~$4K; account #701312.04: In progress:  Scott waiting for lower price

ACTION:  Go back to Mark Brown and ask who we should go with (Jim): Finished (Tapemation is it unless we want to go back east) 

 

GUI Development

  • Mission script GUI introduction

Kevin showed how to use the mission script GUI located here.
Bugs for this GUI can be reported here

On Table:

Chris P. must work with Brent before spring deployments to solve sampling problem
Chris P. and Brent need to address high volume issues for Sept deployment.
BIOSA integration as a contextual sensor.  ACTION: how will BIOSA integrate and drivers needed (Brent & Wayne)
