Exercise Wheel Tracker Confirms Suspicions About Cats
Originally published on hackaday.com by Dan Maloney on 5 December 2024
Brent decided to track his cat Luna’s activity by instrumenting her cat exercise wheel using an M5Stack ESP32 module and a magnetic reed switch. To detect movement, he attached neodymium magnets to the wheel, which triggered the reed switch twice per revolution. The ESP32 recorded the pulses, processed them to debounce the signal, and calculated Luna’s exercise stats, including time and distance. This data was uploaded to OpenSearch for detailed analysis and visualization.
Luna’s activity patterns revealed she frequently uses the wheel around 4:00 AM, causing sleep deprivation for Brent, with another burst of activity during the evening zoomies at 6:00 PM. The rest of her day, unsurprisingly, is mostly spent sleeping. Brent has shared his code and OpenSearch setup, enabling others to replicate the project.
This creative and humorous project offers a glimpse into cat behavior while providing a practical tool for tracking pet activity. It’s perfect for anyone curious about their feline’s daily antics—or just looking for a way to stay entertained!
