iCubeSmart 3D LED Cube Kit 8x8x8 (3D8S-MULTI) | DIY Soldering Electronics Project

Experience a hands-on journey into light and electronics with the iCubeSmart 3D LED Cube Kit. This DIY welding package builds a vivid 512-LED 3D cube, arranged in a precise 8x8x8 matrix. When powered, the cube comes alive with bright, shimmering colors and dynamic shapes that you can influence with hardware and software tweaks.

Designed for learners and makers, the kit blends tactile soldering with digital artistry. The cube sits on a compact footprint, roughly 7.1 by 7.3 by 7.9 inches when assembled, with 0.9-inch lamp spacing that gives a crisp, evenly lit matrix. The board ships with a pre-mounted main PCB and requires you to solder the LEDs into 64 fixed positions, reinforcing practical electronics skills while still offering room for creative exploration.

Kit highlights

• 512 RGB LED lamps create a full spectrum display across eight layers.
• 8x8x8 cube geometry with precisely measured 0.9-inch spacing for clean light separation.
• 64 soldering holes on the main board simplify LED placement and alignment.
• USB-C power enables easy, modern power delivery and portability.
• Eight control keys let you switch animation modes directly on the cube.
• Microphone on the motherboard enables audio-synced lighting in a dedicated mode.
• More than 20 built-in animation effects offer immediate visual feedback after wiring.
• HEX-based customization via provided 3D software lets you generate new animations for the cube.
• Lifetime technical support from iCubeSmart’s team with 15 years of DIY light cube experience.

Getting started and practical uses

• Ideal for STEM classrooms, maker spaces, or a thoughtful gift for hands-on learners.
• Great as a striking desk or display piece that demonstrates color mixing and lighting timing.
• Encourages experimentation with electronics, coding, and 3D software workflow.
• Software-generated HEX files enable custom animation runs without complex programming.

Specifications at a glance: 512 RGB LEDs, an assembled size around 7.08 x 7.28 x 7.88 inches, 0.9-inch LED spacing, a 18 x 18.5 cm main PCB, and a 5V USB-C power supply. The kit is intended for users with basic electronics familiarity and soldering ability, not recommended for children under 12, but it rewards careful work with vivid, multi-color displays.
