ESP Engineering Mtg -- Feb 21, 2008

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

LATEST Deployment Schedule is HERE. 

Tech Transfer

Discussion Items:

• Update on Mack progress
  • Cheri noticed on Tuesday (19th) that the compression bolts are not gripping the motor shafts tightly enough.  This stopped all preparation for the mock-mission run, and demanded a re-design of the valve/motor connection, which Doug helped brainstorm and propose a solution.  2mm balls are required for the fix, and, after calling every ball bearing place in 3 counties, we had to rely on MacMaster (delivered today).

•  Mike Parker contacted about piezoprinter problems (holding down membrane, cutting out disks) and is designing solutions.  Also will be approached about a puck holder.

• New syringes.
  • Still not heard back from company

• Screens and scintered frits
•  
  • CE metalurgical will create a 'stamp' to label the frits.  Cost is $300/tool.  Will label at 1/2radius on one side of frit.

• Puck Laser Etching
  • Mike put in SAF bottom holes, but got confirmation from El Camino on remaining pucks to not forget that again.  Remaining pucks from first batch ready for etching.  Then to send out lot3 for etching.  Have spoken to Roman and Nilo about this. 

MFB

Discussion Items:

 After seasoning the tube, gels show that we are getting product produced (using calf thymus).  Addie will begin work for the Moore year-end report.

Software

• puck heating control
  • Brent has gotten calibration w/in 4degrees, but measuring puck temp is problematic.
• Firmware 'lock-down'?
  • Thermal boards and Dwarf boards look fine, but the failing home sensor in the hand seems to generate a cascade of failures.  This will be fixed.(Brent)
  • GG and Neo will have old firmware and old Ruby.  Mack will use newer of each and these versions need to be kept separate.

Sphere and 4K DWSMS

• Sphere update
  • No word or update from Wah Chang.

• DWSM progress?
  • Doug believes he's found a pump that will push reliable, reproducible amounts of fluid.  Ordering motor to run it, and now must test that it pushes the correct volumes of fluids with no back-flow.
• Battery boxes?  Will order 1 box (~$2200; acct 701312.04; Scott)

ACTION:  Have BATTERIES been ordered? (Jose)
ACTION:  Change cracked power connector on GG's lid (Cheri) 

GUI Development

• Mission script GUI introduction

Kevin has placed new GUI on the server here.  Rich Schramm available to do data parsing work; we want to utilize this by Sept deployment.

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.
