Week 6 Update

What was accomplished:

  1. Finished working on the PPT for Tuesday, and took major feedback on issues with peristaltic pump(including potential issues with air being pumped out instead of actual liquid)

  2. Re-designed a spin coater to fit on to the overall automated assembly

  3. Read about other spin coater + liquid handling setups, and how they managed to deal with liquid handling consistency issues(THEY USED SYRINGE NEEDLES SINCE THEY WILL PREVENT LIQUID FROM FLOWING DOWN WHILE AIR CAN SO ATTACHING IT TO THE SILICON WOULD SOLVE POTENTIAL ISSUES WITH NON-CHEMICALS)

Roadblocks/issues:

  1. Not sure if the current silicone tubing for the peristaltic pump is small enough to attach re-usable syringe needles

  2. Need to debug peristaltic pump accuracy for accuracy regarding how consistent liquid handling is(we can do something like 3 trials for consistent 5 ml of liquid to debug)

TO DOs:

  1. CAD a new control panel for the overall raspberry pi setup

  2. Order components for SMALLER silicone tubing with luer locks(that can attach a syringe needle), as well as linear actuators and silicone/glass syringes, since they allow easier control of precise liquid handling control
