Every night as part of vivid festival the Sydney Harbor Bridge lights up with LED's controlled by you on the ground.
In the harbor, cruise ships and ferrries also have LED lights that change color depending on their location.
I'm Lexy Savvides for CNET, let's go take a closer look at the tech behind the scene.
There are 2,000 one-meter LED tubes we have 140 high output LED cans, 1.1 kilometers of fiber optic cabling, we've got 8.5 kilometers of six cabling, three and a half kilometers of power cabling, 950 meters of free phrase, 12 distros, and 20,000 title songs.
There are only about, bit over 150,000 control channels.
The way, the way determine what color of [UNKNOWN] is we just have a simple GPS chip, which determines a location to within approximately five meters.
And then we have a table which simply decides which color is which for those different areas of the harbor.
So, the Galileo board is, development board that's being designed by Intel.
And what it is is the first x86 processor to fit into the Edwina ecosystem.
The Edwina ecosystem is fantastic, in terms of accessibility for beginners.
There's a tons of documentation out there and plenty of people have written libraries that make it really easy to use.
We've actually built a custom PCB that shield on [UNKNOWN] boat.
And what that does, is it provides us with a GPS chip which can interface through standard input output systems.
And allow us to use a standard library that already exists.
In terms of testing, I had a few sort of odd nights where.
I was driving around my suburb in a car lit up by about 200 LED's and making quite a spectacle of myself I would say.
