Project Ideas for Fall, 2022

Potentiostat/Galvanostat/EIS Device

• Matsubara, Yasuo. “A Small yet Complete Framework for a Potentiostat, Galvanostat, and Electrochemical Impedance Spectrometer.” (2021): 3362-3370. https://pubs.acs.org/doi/full/10.1021/acs.jchemed.1c00228

CO2 Sensor for Absorption Experiments

Build a CO2 sensor with integrated humdity and temperature sensors.

• Specify interface requirements for a usable laboratory device.

• Develop a microcrontroller interface to operate the sensor.

• Build and demonstrate a breadboard prototype.

• If possible, design, print, aand install and operate with CBE Lab II CO2 absorption experiment, or separately test wtih commercial seltzer water dispensers.

Device options

• Adafruit SCD-40 and SCD-41 Adafruit SCD-40 - True CO2, Temperature and Humidity Sensor - STEMMA QT / Qwiic [overview][SCD-40 product page] [SCD-41 product page] Note the SCD-41 offers wider range, higher accuracy, and several low power operating modes at moderately higher cost.

• Seeed Wio RP2040 mini Dev Board - Onboard Wifi product page

• Arduino Nano RP2040 Connect Review: Built-in Wi-Fi and BLE [Tom’s Hardware Review]

• Adafruit Feather RP2040 [Tom’s Hardware Review]

Microsope

Build a microscope. Use Raspberry Pi HQ camera, C-mount microscope lens.
