Internet-connected hamster wheel

thingiverse

Hamster wheel with hall sensors for rotation count/speed/direction. The wheel runs silent on a 608 ball bearing. The wheel is decorated with the names of our two hamsters (Pjotr and Ilya, they're Siberian dwarf hamsters), but there is a version of the wheel stl that has no names. I'm working on a more elaborate write-up of the complete project [here](https://rurandom.org/justintime/w/Internet_of_Hamsters). This includes descriptions of the electronics and software. In our home, an attached ESP8266 wifi-enabled microcontroller sends statistics that end up in an elastic search server (If you live in Europe, be sure to [ask your hamsters for consent](https://en.wikipedia.org/wiki/General_Data_Protection_Regulation) first). For those interested in hamster fitness, this has taught me that: * My hamsters can run at a top speed of 4.9 km/h and on average make 2.5 km/h; * They almost exclusively use the wheel between 1 and 7 am; * Combined, the two of them walk a distance of between 1.5 and 6 km each night. The screen is housed in an adaptation of [Octoprint 3D Printer Status Monitor - Wemos D1 Mini & SSD1306 by Stevetecx](www.thingiverse.com/thing:3080488). The housing is adapted to be clamped between the bars of the cage. The wheel itself was inspired by [Run Mousey Run (Exercise Wheel)](https://www.thingiverse.com/thing:1083729), though designed from scratch. The names were drawn in Inkscape and then converted through some variant of ["Inkscape to Openscad converter"](https://www.thingiverse.com/thing:25036).
