CUBEx8 is my attempt to create a lower cost, easier to assemble 3D LED cube kit. The goal is to squeeze the design down to the bare minimum components yet still have a nice looking and fun to build kit that any maker would be proud to show.
One key aspect of this cube design is that the maker gets to use their favorite controller board. While I don't include a controller in the kit, the base board of the kit does include a 3.3V to 5V level translator that can be used or bypassed. Some controller boards have 5V I/O and won't need the translator. Other boards have 3.3V I/O and the translator will be required.
The kit is comprised of a base board that can be mounted vertically or horizontally as desired. There are eight LED boards and each board will need to have a header soldered onto it. At that point the LED boards simply snap into the base board press-fit style. They can be soldered or not, allowing the cube to be disassembled and reassembled very easily.
A major goal is requiring some assembly, but not an overwhelming amount. Simple soldering skills are all that is required and the CUBEx8 will be easy to build.
Please follow the project logs to understand the entire design process as I work my way from idea to sketches, to prototypes and settle on a final kit design. I will detail design trade-offs and explain how various decisions impact cost-of-goods-sold (COGS) and manufacturability.
