    mdq-cyborg is a reimagined Mar del Plata souvenir: a DIY weather station that queries an API to obtain temperature and humidity data—akin to the classic sea lion weather figurines.

    The device is built around an ESP-WROOM board connected to three LEDs that translate the API data into humidity levels: blue (normal), violet (medium), and pink (high). Its v1 also featured a DHT22 temperature/humidity sensor, later replaced by the Open-Meteo API.
