  1. Team Members: Kyle Bloomer Josh Geiman Lucas Bennett Potentiostat

  2. Background Info • Dr. Cindy Harnett's laboratory is in need of around 15 potentiostats for testing a variety of devices

  3. Background info • What the system does • How it works • Expense of other commercial potentiostats • Why it is important

  4. Doziers explanation • Potentiostat holds Voltage constant and puts out the current needed • Galvanostat does vise versa

  5. Background info • What we received from Ben • 2 electrode vs 3 electrode • Explanation of using Cheapstat instead of Arduo

  6. Background info • How to use it • Application or example (preferably Chlorine gen or fuel cell)

  7. Project Requirements • Potentiostat can be easily built by students • Must cost under $100 • Must have the ability to measure Electrochemical potential • Must be easy to use

  8. Function of System • Function of system as an entity • Measures characteristics of electrolytic cells • Allocate • PC come through USB to potentiostat via GUI(don’t use the word GUI ;))

  11. Potentiostat Requirements

  12. System Diagram

  13. Data/Display Management System Requirements • The Data/Display Management System manages three sub components • System control • Software on the PC will provide the user with means to specify the appropriate parameters • Data logging • The PC will have the ability to keep records of the measurements returned from the Potentiostat • Data display • After testing is successfully finished, the user will have the ability to view results on the PC

  14. System Diagram

  15. Voltage Converter

  16. Operational Concept • The PC is connected to the potentiostat • Software with a Graphical User Interface program will run on a PC • The user will have the ability to change configuration of the test device through the GUI program to send to the potentiostat • Once the potentiostat is finished executing the test, the user will then receive the results through the software and have the ability to review them on the GUI.

  17. External Interfaces • PC with USB connection • For the Potentiostat to communicate with the PC, a connection must be established through a USB interface • DC Power Converter • A DC power converter must be utilized within the system to allow 120VAC, 60Hz, and 15A of operational power

  18. Internal Interface • USB Connection • Windows Operating System • Software to Software Interface

  19. Intelligent Potentiostat Requirements • The Potentiostat manages two functions • Data communication • The function of this subcomponent is to communicate all data from the PC Interfacing Control to the Potentiostat system • Device Under Test (DUT) measurement

  20. Data/Display Management System Software • Data/Display Management System • The Data/Display Management System will handle 4 main requirements through C# Program • Simplistic GUI for Data Controlling • Transmit the configuration to the controller • Initiates measurement process • Retrieves raw data

  21. System Description • The PC Software will allow user to configure the test profile • The user will have the ability to select various waveforms and also set the maximum voltage applied by the potentiostat • The results of each measurement will then be reported back to the user

  22. Current Status • CheapStat Parts have been ordered • Designing the GUI portion of the PC Software to best fit requirements • Testing preexisting Cheapstat code set
