Spring 2012:Leanna Morinishi Journal

Week 5 - Mar 4-10

Mar 5

• Slaving on the wiki. Put in a simple navbar, reorganization. Did some literature searching, and started my objectives for the final project. Will be working with AJ and Vincent on Lab II.

Week 4 - Feb 26-Mar 3

Mar 2

• BIG MANUPS got the code to actually work. After thinking and talking with Steve about what voltage to subtract and where, the stage finally moves towards the center after 1 cycle in each direction, given that the amplitude is large enough to see the entirety of the bead.

Mar 1

• Wrote code to sort tether data into a force-displacement curve and used nlinfit to determine contour and persistence lengths. See Leanna Morinishi Lab 1.

Feb 28

• Got integration working, Also, the stage is moving nicely, we are currently using 3 sinusoidal cycles, but for the sake of the tether, we will begin to cut this down to 1 in each direction.
• Switched gears a bit so that we no longer invoke piezos, we give a voltage and redefine a new UiSettings attribute in each round.

Week 3 - Feb 19-25

Feb 25

• Integrated with OTKB and tried to open communication with GUI, it's a start

Feb 23

• Met with AJ, decided to pair up, shared code

Feb 20

• 3pm Moved some voltage through the DAQ today. Worked on understanding time, SampleRate, SamplesPerTrigger, TriggerRepeat, RepeatOutput, establishing channels, starting and stopping data output and input.

Week 2 - Feb 12-18

Feb 15

• 1.30pm DNA Tether Prep with Marie's leftover materials, Steve found a few attached beads on his samples, I found one.

Feb 13

• 12pm Walkthrough of OTKB software and took some great calibration data at 20mW 70mW and 120mW of .97 micron beads.

Week 1 - Feb 6-11
