I’m sure you’ve seen the Sphere at The Venetian Resort in Las Vegas. I believe this is the largest spherical building in the world—a snip at only $2.3 billion.

The outside surface of the sphere features 580,000 square ft (54,000 square meters) of programmable lighting. This is presented in the form of 1.2 million hockey puck-sized arrays of light-emitting diodes (LEDs), where each of these arrays contains 48 individual tricolor LEDs.

It’s no secret that I love LEDs. “Show me a LED flashing, and I’ll show you a man drooling,” as I often say. Since the original’s inception, I’ve seen several do-it-yourself (DIY) miniature versions that I’ve found tempting, such as this little scamp by Jiri Praus.

Well, I just ran across the best contender thus far in the form of this little beauty by Carl Bugeja. I love the way Carl describes the evolution of his innovative solution to creating a spherical array of equally spaced LEDs.

From his microbots website, we discover that Carl heads a small team of electronic engineering geeks, and that this team is based in Malta, which is one of the smallest islands in Europe. Also, from their “About Us” page, we learn that the microbots team is on a mission “to simplify electronics and robotics, whilst making our projects more accessible to makers, students, and engineers!”

I was just bouncing around Carl’s YouTube Channel. I love his work. I’ve never been to Malta, but if I ever manage to make my way there, I’ll be sure to visit the folks at microbots and report further. In the meantime, what do you think about Carl’s creations?
