Micro-SD Card Low Power Showdown – Part II
In 2020, I worked with an intern to characterize SD power characteristics (view the archive). As my colleagues and I embark on a mass deployment of new devices in 2025, it is time to revisit the perennial question: what SD card is best? Specifically, what SD card has the lowest current draw in an Arduino-based, […]
Using Hublink.cloud to Wirelessly Transfer FED3 Data
Learn how Hublink.cloud addresses challenges in wirelessly transferring SD card data from FED3 devices used in behavioral neuroscience experiments.
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)?
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.
GR/PR: An open-source grip strength meter
In animal models of limb disuse, grip strength (or force) is a measure used to characterize the time course and severity of muscle atrophy.
Evaluating a 60GHz mmWave radar system
Accuracy and applicability of Seeed Studio 60GHz mmWave Sensor (Breathing and Heartbeat Module) based on the MR60BHA1 60GHz radar module
