Meet Marvin, my very first sculpture. I named the little guy after Marvin P. Middlemark, the brain behind the rabbit ears TV antenna. It felt right since my creation rocks antennas too. I took cues from Mohits Boxy’s design, and being more at ease with ESP microcontrollers, I went with a HiLetgo ESP32 Dev board to bring Marvin to life.
