I was recently contacted by a representative from ITEAD Studios and asked if I would be interested in taking a look at their new smart home switches. It looked like a fun product, so I happily agreed. My samples arrived a few days ago, and I’ve had a little time to play with them, so… Read More »

Syma X5C-1 Quadcopter

My nine-year-old son wanted a quadcopter this Christmas, an idea I was honestly a little excited about myself.  After a bit of investigation, the Syma X5C-1 appeared to be the perfect option, offering great stability and the ability to fly it outdoors.  As a bonus, it also comes with a built-in HD camera.  I was… Read More »
