From the project
56 LED rotating color display with RP2040 and ESP32 microcontrollers
The Rotating Color Display device comprises two primary units: a power supply unit and a display board (figure 1). Both are circular in design, with a diameter of 120mm, similar to the dimensions of a standard Compact Disk. The display board is rotated by a CD motor. Energy is wirelessly transmitted from the power supply unit to the display board, eliminating the need for wired connections.
