Case Studies
Using the ESP32-S3 ULP Coprocessor with the Arduino IDE
The ESP32 devices’ Ultra-Low-Power (ULP) coprocessor enables access to peripherals such as RTC GPIO, RTC I2C, SAR ADC, or temperature sensors (TSENS).
How to Measure Electrode Impedance on the Bench
Impedance is the opposition to electrical current in a circuit, and in brain electrodes, it matters because high impedance can reduce signal quality, leading to poor detection of neural activity or inefficient stimulation delivery.
An Unofficial FED Cleaning Protocol
FED failures can be traced to IR sensor and circuit board issues, which can be remediated with an isopropyl wash.
At-a-distance Liquid Measurement Sensor for Tracking Sub-mL Consumption
Here, we present a tube-based magnet float and enclosed magnetic sensor array to determine and record sub-milliliter liquid intake every 10s called “Tubetrode”.
A Leak-proof Countermeasure for 3D-printed Vessels Under Pressure
We aimed to determine if a spray coating could mitigate leaking. Furthermore, if deployed as a submersible/vessel, could our parts withstand acute exposure to external pressure (e.g., up to 80 meters)?
Leveraging the OpenAI Assistant for a Customized Chatbot Experience: A Technical Overview
In this article, I aim to show the process of integrating the OpenAI Assistant into a web-based chatbot.
Conductive epoxy PCB vias: How small can you go?
We investigated how small vias can be made when using conductive epoxy to make 2-layer PCBs using in-house manufacturing techniques.
An Anesthesia Mask for Dunnarts: Neuroscience in a Non-traditional Marsupial
Recently, Richards Lab has been investigating cortical activity patterns but has been limited by their ability to perform long-duration anesthesia on dunnarts.
