Background

  • Nice wikipedia description of what a potentiostat is here.

  • A basic description of potentiostat architectures can be found at http://www.consultrsr.com/resources/pstats/design.htm

  • CheapStat -- PLOSOne article here -- they use a DIY design to assess ascorbic acid in orange juice, cyanide in water, acetaminophen content of over-the-counter pain medication, and arsenic in water. Neat!

  • An open potentiostat at Cornell is here

Uses

  • Assess arsenic, cyanide, other contaminants / toxins in water
  • Educational
  • Identifying toxins / ingredients in foodstuffs

Development

  • olm-pstat - repository for the PLOTS/PVOS Open Lab Monitor potentiostat peripheral
  • source code from Jack Summers' DIY potentiostat

OHS 2013

  • Table - should have power
  • Device - need to try chem experiment. Craig
  • Experiment materials. Craig. Two sets of cables, to avoid contamination.
  • Code - realtime plot in Python. Craig
  • Serial library patch
  • Applications: describe what this can do. Don
  • Feedback/sign up form. Ian
  • Cards with logo. In a week. Jake will order.
  • Schematic. Craig or Don make SVG diagram. High level and lower level of feedback loop
  • Data sample image - python output, Craig
  • Reference list:
  • electro-chemistry textbook
  • Jack
  • PVOS GitHub repo
  • various current publications on potentiostats
  • Instructions on setup - Ian will contact Kipp. Do we get free passes as demoers, or do we need to order tickets?
  • PVOS logo into Badger form - Ian
