This video was shot under bright lights, making the cube itself easier to see. I'm hoping my software will convince a few people to build a cube who might not otherwise! I am publishing this mostly because I have a lot of experience writing cube software. I hadn't seen the earlier one until I started this writeup, so my pinouts are different, and the resistor values are different, but otherwise,the hardware is almost identical. The hardware in both projects is almost identical. MEGA DAS published a similar project here in 2017. NOTE: Before I go any further here, I'm not the first to suggest a 5x5x5 cube powered with a MEGA. The third is here - a 8x8x8 single color cube, again with minimum external hardware. It is a 5x5x5 RGB cube, very similar in design to this cube, but a harder to build. This is actually the first of three projects like this. I have written a whole lot of code for big cubes in the past, so I have adapted a bunch of existing cube animations to run on this 5x5x5 cube. (I've tried it.) You really need to design and fabricate a PC board if you want to use them. Why do I want to avoid shift registers? Because they are absolutely horrible to hand wire. So this is a 5x5x5 cube that can be powered directly by an Arduino Mega without shift registers of any auxiliary hardware other than 5 transistors (used to pull a whole layer - the cathodes of 25 LED's, to ground). My objective from the start of this project was to create an easy to build cube and then create enough cool software to make it possible to enjoy the feel of a big cube without all the drudgery required to build a big one. But they really aren't the same as a big cube.

Small ones (3x3x3 or 4x4x4) are easy to build, both because they don't require large numbers of LEDs, but also because they don't require external hardware like shift registers and high-side drivers to manage the cube. Most people love LED cubes, but big ones, like 8x8x8, are a lot of work both to build and to program.
