I set out to build the 4x4x4 Charliecube using an Arduino Nano. The cube itself is pretty tough to build, starting with the actual soldering all the way through what can be some messy code. Soldering experience is definitely required.
Materials I would say are needed:
I used two different sites extensively during the building of the cube.
Gunderson.net - link here helped me with the 3D tools and showing me exactly how to implement them. Some of their photos are used throughout this guide.
Asher Glick - link here helped me with the libraries and starter code as well as the wiring diagrams to get this project off the ground. All of the wiring diagrams come from this site.
This step while easy is very important. Using the 3D printed tool saved me a lot of wasted LEDs. Here, you put the LED in the tool and bend in the following order. I oriented the LED so the tallest lead was in the second position from left.
Doing this correctly ensures no wiring issues when going to solder the towers.
