The Rotating Display is a compact disc-sized device that rotates quietly using a CD motor. It features 40 LEDs that display time and weather data sourced from the internet. The device is wirelessly powered and controlled via a user-friendly web interface. It uses Arduino nano and ESP-01s microcontrollers and is easy to assemble. ## 1. Description of the device The Rotating 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. **Figure 1: Rotating Display assembly.** The lower PCB is the power supply with wireless power transmission, the upper PCB is the display board.
