Mollie the Hamster, on Strava: https://strava.app.link/FMubyPjMa5b

Project: > The main parts are an ESP32 attached to a hall sensor, which I positioned close to the wheel. Using a magnet attached to the back of the wheel, this tells the ESP32 when a full rotation has completed. It gives a timestamp (and total distance) to each magnet-pass, which is stored on the network. A python script (on my laptop) then retrieves this data in the morning, turns it into a .FIT file, and uploads it to Strava through the Strava API (with a randomly chosen run title, taken from a mostly AI-generated list of options, as I needed >100). In terms of manual additions, I had to add the photo manually, and Mollie had to do the running.

Neat! Not to toot my own horn too much, but I put together a similar project for my cat's exercise wheel. Hackaday featured it a while back: https://hackaday.com/2023/04/02/spy-on-your-cat-to-make-sure...

His exercise routine is somewhat variable but he usually goes for a short jog a few dozen times a day. Most often at 5 am, for whatever reason.

Since the article I also built and hooked up a treat dispenser for extra motivation.

If you look at any neuroscience paper, mice will run 10k a day or more on a wheel overnight. I thought the axis labels were wrong when I first saw that type of study. It’s quite common.
