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.
- Calculate persistence and contour lengths by nlinfit
- Force Function for nlinfit
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
