Melina Zhu, Deepa Kamath Kasaragod, and colleagues at the department of Neurobiology at the Hiroshima University in Japan, developed a device called the wheel-running activity acquisition (WRAQ) system. It track the circadian rhythms of rodents using a microcontroller, powered by a lithium polymer battery, and surveys exercise activity for up to 30 days. Data can be stored on a microSD card or using an online server using a WiFi connection. Python software is provide to interface the system with ActogramJ to analyze chronobiological aspects of the data. A link is provided below to the design files and documentation on programming WRAQ using Python. Most commonly used in neuroscience studies with rodent subjects, the WRAQ apparatus is a cost-effective way to monitor wheel-running activity of rodents in caged environments.
