More Wheatstone Bridge Notes

  • Wheatstone bridges tested and working.  The 5th one had a loose connection on the positive signal line but is working now.
  • Made a slight error  in orientation.  The Amplifier is actually in the reverse order of the bridges.  The bridges go E+,S-, S+, E- and the  amplifier is E-, S+, S-, E+.  Tis means you have to cross the connections.
  • All terminals are wired and ready to be attached to strain gauges and amplifiers.
  • Best to position it so Amps are on the left side of the bridge, where ever we end up placing it on the unit.  This allows you to have testers in your left hand, while making calibration adjustments with your right.  Doing this in reverse is annoying to say the least.

  • Fixed a bug with multiple selection and the map widget
  • Any selections made in the map widget are now reflected in the data tab of the AdvancedQueryWidget
  • Tried to help Phil with some build problems but of course when you expect something to fail it works just fine…
  • Added a “New Widget’ button to the network widget.  Clicking it while in either the map mode or the connection list will spawn a new AQW with both the selected nodes and any connections that refer to them.

  • prepping PPM for demo
  • found some bugs
    • fixed SQL error on saving Funding Request after initial save
    • fixed SQL error on saving Project after initial save – reload of Funding data required….
  • cannot use uid as a property/field name as it’s reserved… causes datagrid to go nuts!
  • added changedFlag to Funding Request, used for Close Confirmation
  • removed Tab focus on Validators, added Alert

  • Deployed new VSS
  • talked to JW about documentation and querylog
  • Need to request 4 Flexbuilder 4 licenses – done
  • Need to write up description of why we need PRIVAC – done
  • Walk through PPM with Dong and burn a new disk – done. Still some possible problems with null pointers in the “Enter Financial Data” section, and the contract info isn’t in yet.
  • My code works fine on Mike’s machine. If rebooting the laptop doesn’t work, it’s probably time to install a new version of Eclipse.

Wheatstone Bridges complete

  • Completed 5 wheatstone bridges.
  • The connection go from left to right with the side of four on the bottom: SG 1 connection A, SG 1 connection B, SG 2 connection A, SG2 connection B, E+, S+, S-, E-.
  • Ran out of space on the last one so I had to put it on the other side the connections are still in the exact same order as the bottom, its not mirrored.  It is a little messy compared to others but hopefully it works.
  • Still need to wire the terminals but the hard parts done.

  • changing DIRECT CITE to datagrid
    • create direct_cites table and added delete cascade on funding_request table
    • AddDirectiCiteWindow, DirectCites.mxml created to handle multiple direct cites
    • Funding Request panel remains after save
    • subsequent save overwrites previous one
  • added ‘%’ to the goals

7:30 – 11:00 VISIBILITY

  • Verified PPM meeting with Trish for 9:00 Thursday
  • Script runner for Querylog is working fine
  • Looked some more for the source of my memory problems. I’m thinking that it might have to do with where I’ve put the images folder. Sent a note to Mike asking him to try it out in his environment.
  • Burned a new copy for Scripting

11:00 – 4:00 FP

  • Adding the wrist actuator and possibly the fingers
  • Got everything up to the finger mounts installed. Next will be the fingers and the base.
  • KF System with linkages and finger mounts

Feldman Project Wheatstone Bridges

  • Using resistors which are significantly higher then the resistance of the strain gauges, makes the bridge not able to be balanced.
  • Using resistors which are significantly lower then the resistance of the strain gauges, makes the bridge to sensitive.
  • If we ever have a reason to needs something to be ultra sensitive, 1k ohm resistors would be good otherwise, stick with 1.3k ohm.
  • 5 more Wheatstone bridges in production.  Need more 8 prong terminals and 4 prong connectors to  complete them (which I’ll get tomorrow).

Mike 6.28.2010

  • Added labels to the StatusList item renderers on AdvancedQueryWidgets
  • Added the ability to change what field the labels were pulled from at run-time (not easy)
  • Added multiple selection to the StatusList
  • Selection changes made in the status list are now reflected in the data tab of AdvancedQueryWidgets
  • Added selection and multiple selection to the map component

  • fixed SQL Error on AddUser
  • AddUserForm modified to use on Registration, all the fields are shown
  • fixed Create Project Panel now showing after logout
  • Funding Request
    • remains open when saved
    • removed Certify and Accept buttons
    • corrected Obligation Amount not loading
    • all the contact fields are editable and stored in the table

  • Sent Trish a note to reschedule meeting from Friday to Thursday. After getting to the office, it looks as though the meeting was already scheduled for Thursday 0900.
  • Went over the change requests with Dong
  • Chasing the bug that clears out the interval_minutes when scripts are run manually. It looks like the issue is when a script is updated, interval minutes is blown away. Fixed.
  • Was looking at Mike’s changes to the network widget, and made the suggestion that rather than selecting single lines in the table, that we use the name field (either in the chart or the selected line on the grid) to create a query that preserves the networking information, along the lines of:
    • select `Name`, `souRce`, `targeT`, `icon`, `text` where (Name = ‘Jason’ or souRce = ‘Jason’ or targeT = ‘Jason’) or (Name = ‘Mary’ or souRce = ‘Mary’ or targeT = ‘Mary’) or (Name = ‘Mark’ or souRce = ‘Mark’ or targeT = ‘Mark’)
    • This gets us away from having to deal with the uid as the means by which we determine what rows we’re getting and allows for a network-based drilldown into the data.
    • Maybe this means that instead of having the query be added to the data page, that we build the query in the network view using a “new widget” button like for the other charts.
  • Pulling slideshow off into its own SWC. I’m pulling a lot out of vis2, so if anyone does any work in there, please let me know!
    • Having huge memory leak problems compiling the app now that I’m including the slideshow library.  Compiles fine with maven.
    • Interestingly, the swc compiled using maven is 2781kb, while the flexbuilder version is 2783 kb.

Need to order

8:00 – 4:00 VISIBILITY

  • Discovered that running a script manually clears the autorun table. Need to fix that.
  • Meeting with Anne about potential work.
  • Meeting with Trish about PPM. Notes follow:
    • User registration (at login) needs all the new fields (email, address, etc). Also, fix scroll bars
    • Unable to add user from “register” screen. SqlException: Column count doesn’t match value count at row 1. I have a printout of the error
    • After playing with the above, and then loggin in as “projportfolio”, the “create project” panel did not come up when the menu selection was made.
    • Need to add a warning “Are you sure that you want to close this project without saving”
    • Funding Request
      • In “Add Funding” basic panel, make all the fields editable. The form may be sent to people who are not in the system
      • Closing and selecting dropdowns in the details view causes the panel to change back to the “basic” (Note: This happened on Trish’s machine, but not my FGM laptop)
      • Finance Data
        • Funding request should not close when saved
        • Can delete the Certify and Accept buttons.
        • Alert the user if the various amounts do not equal the “Funding Amount” from the “Funding Request Details” tab.
        • Acceptance date should be moved to after Document Number
        • Direct Cite can have multiple entries. Rewrite so that it more resembles the line item grid from Project Creation
        • Obligation amount is lost on the reload
    • Financial Data
      • Where are goals edited?
      • The maximize button has to be clicked twice to get the first maximize to work
      • “Obligation Goals” should be “Obligation Goal %”, also add % in data, just like other rows.
      • Add Contract info to financial data forms (not sure if this can be guessed at based on other project data entered or not. This data can then be shown in the “Manage Contract” grid.
        • Contractor/Vendor:
        • Contract Number / Amount:
        • Contract Type:
        • Period of Performance:
        • New or existing Contract:

FP notes:

  • working at home
  • changed FinancialDataCanvas( ManagedCanvas to VBox) and  FinancialDataSetCanvas (SaveStatePanel to CollapsiblePanel), it looks more manageable and doesn’t crash….
  • couldn’t duplicate the chart crash

Viz-n ssh

  • ssh connections to viz-n now require a public key.
  • The key file doesn’t work with cygwin but does work with Putty.
  • Using Putty type port 1033 and switch it to SSH in the session settings.
  • Under Connection->SSH->Auth add the private key file. (This can be found in the downloads folder on the ftp server)
  • Open it and log in as vizncom.
  • To restart the tomcat cd /appservers/apache-tomcat-6.0.26/bin and run ./ wait a few seconds and then run ./
  • If tomcat crashes this should fix it.
