HoloCubic is a multi-function transparent display “desktop station” that uses a dispersive prism to create a pseudo-holographic visual effect, combined with WiFi and Bluetooth connectivity to support interactive network-capable applications. Built around an ESP32 PICO-D4 microcontroller, a 1.3″ 240×240 ST7789 display and MPU6050 inertial sensor, the device allows you to build a “floating hologram” style display module with additional networked visual features like weather display or follower counts. The hardware design includes versions of the PCB (Naive version, Ironman version) and 3D model files for the enclosure (3D printed or CNC metal). The software leverages LVGL (a GUI library for microcontrollers) and supports surface touch or IMU-based input. Because it connects via WiFi/Bluetooth, it can fetch live data and display dynamic content, bridging embedded display, network, and interactive gadget design.
