Do you have a Google Chromecast? [we probably have more than 6 ourselves]. If not, you are totally missing out on one of life's little conveniences when it comes to sending media content from your Computer, Smart Phones, and Tablets over to the big screen in your living room. If you're still not quite sure what it is, here's an overview video below from the GearAddix team (below). If you know how it works, you can skip on to the rest of the article.
That video might be a bit outdated as there have been several software upgrades to the product, so it's a lot more full featured. One of those new features (available on Android only) is Screen Casting. You can now cast your entire mobile device screen over to any large television. This has been handy for me as I like to take notes on my Galaxy Tablet, and by broadcasting it to the large 4K TV here at the office we now have a digital White Board in which we can save all of our note taking.

Ok, so many of you are interested in DSLR Video, so all this tech chatter probably doesn't mean much, but here's a very cool tip you video shooters may find handy. With the ability to screen cast from your device you can broadcast your Canon DSLR Video wirelessly over to any HDMI monitor or Big Screen. By using the DSLR Controller (android app) and a special USB OTG Cable, the app works as a preview monitor and to control the cameras settings [similar to the EOS Utility Software on a desktop]. Since the App runs on your android device, you can screen cast over to your Google Chromecast which is connected via HDMI to any monitor. Check out the demonstration video below.
Regardless if you're going to use it for DSLR Video, the Google Chromecast actually makes a perfect affordable XMAS present. My kids stream YouTube and Netflix from their iPods all day long over to the television. At around $30 Bucks, it's certainly worth the buy and if you don't want to move it from TV to TV, grab one for each television in your home. (find it here).
