A few weeks ago, I purchased a Phillips Hue LightStrip and set it up on my computer. Both the hardware and software was easy to setup, making it about a 10 minute process.
The LightStrip itself sticks to whatever you want using some 3M adhesive's on the back of the strip. It then has a connector bridge to connect the strip, power and I assume the WiFi connection to the bridge. Each individual LightStrip package comes with an 80-inch strip. The whole system can be extended by combining multiple strips!
You then have to assign the strip to a room in your Hue App and create an Entertainment Area which helps control and relate all the colored lights in an area. You can think of it as specifying which lights should be controlled by the Hue Sync app, which you'll install later. Luckily, the app makes this part easy as you can typically ONLY assign colored lights to an Entertainment Area.
After this, you should download the Hue Sync program for your computer. After the initial setup, you're then able to config how intense the lights should be and the level of performance the program should have.
Once that's done, you simply start a movie or game, sit back ...and enjoy the show.
It's extremely quick in changing the colors and you can even set the brightness if it becomes too distracting! I'm also going to try and record a few examples while playing some games to show it off then also.
What's even more impressive is that it barely registers as CPU usage on my computer.
My next project is finally getting the lightstrip that my sister owes me and hooking it up to my TV. I've heard that its a more involved process so I have some more research to do.
