Cracking Open the Snapchat Spectacles

Cracking Open Snapchat Spectacles

The Snapchat Spectacles ($130) do a lot more than just protect your eyes. The Spectacles have an embedded camera that lets you record 10-second videos and share them via the Snapchat app on your iPhone or Android device. How did Snapchat turn an average pair of specs into a social media must-have? To find out, I broke out my tools and cracked them open.

You can watch a video of our teardown and read my full hardware analysis in my TechRepublic article, Cracking Open Snapchat Spectacles: Sunglasses that are more than meets the eye.

The Spectacles' 0.52Wh battery might seem puny compared to other prominent wearables like the Apple Watch Series 2 (1.03Wh battery), Moto 360 (1.1Wh battery) or Google Glass Explorer Edition (2.1Wh battery).
