Foni clip is an ESP32 micro-controlled card with an OLED display screen that enables users to generate sunset and sunrise times by pressing either of the buttons on each side. The clip was constructed using, of course, the ESP32, display screen, and buttons, but also with Arduino programming software and an enclosure to help keep the components intact. The producer was inspired to construct the clip from having a deep nostalgic love for the film, SuperBad and watching it with one of his best friends when he was younger.

(Above): In need of a pivot on how to make his design enclosure, the producer decided to construct a visor attachment that would both enclose the PCB and components, along with suspend his clip so it would be displayed properly.
