Matthew Lim developed a simple yet innovative volumetric display using linear motion and persistence-of-vision, employing an ESP32-driven LED matrix moved by a motor with an encoder, creating a 3D floating image without spinning parts, though with some mechanical challenges.
A maker known as mitxela has created a DIY LED candle that features a volumetric display, allowing it to look the same from any angle. The device utilizes an LED matrix board, electronics, an infrared sensor, a coin battery, and a CD drive motor. By making everything spin, including the battery, mitxela was able to create collapsing stars, pouring liquid, and candle flames. The prototype exceeded expectations, and future versions will include more LEDs and improved alignment. The project details, including source code, are available on mitxela's blog.
[mitxela] has created a tiny volumetric "electric candle" display using the persistence of vision concept. The display, made from salvaged parts including a motor from a CD drive, features an 8x10 array of surface-mount LEDs controlled by an RP2040 microcontroller. The project also includes a 3D-printed holder for a sensor and explores generating volumetric data and fluid dynamics calculations for a realistic flame effect.
Mitxela has created a prototype of a miniature volumetric display using an 8x10 LED matrix and various electronics, including a motor from a CD player. The display demonstrates persistence of vision and the potential for higher-resolution versions in the future. The source code is available on GitHub.
