C19 COVID Counter

Personal Project, 09.2022

C19 is, as its name suggests, an indicator for daily COVID-19 infections in Tokyo. I wanted to have an interior-like object that subtly suggests awareness, rather than stressing us too much from daily Corona-related newses.

The device accesses to the web every hour, fetches the number of daily infections in Tokyo. The brass weight hanging from the device is controlled by a small stepper motor, roughly indicates the daily infections by it's height.

To evaluate the MicroPython, this project was completely coded by MicroPython. Daily infections number is fetched from https://github.com/ryo-ma/covid19-japan-web-api
