Passing out during a Netflix session is a very real threat. Especially with the incoming holiday season and all those requisite carbs pumping in your bloodstream. So Netflix's latest make it project attempts to solve the issue with motion sensors built into your socks. (Vaguely festive PR grab, check.)
Netflix has provisioned some sock designs if you're a truly devoted binge-watcher, and offers up all the details for the intermediate-level electronics (Arduino, accelerometers, IR LEDs) needed to make it work.
Your handmade wearables might not work all the time, but at least you'll be a little closer to find exactly which episode of Jessica Jones you unintentionally faded out from.
