How to Build a Netflix IR Sock (That Pauses Netflix When You Fall Asleep)
To help keep sleepy binge-watchers from sleep-"watching," Netflix asks if you're still watching after a semi-short period of time. This means that it could be anywhere from 1 to 5 episodes that you slept through, which is better than 2 seasons, I guess—but it doesn't make it any easier to find out where you left off.
Luckily, they have a better solution—Netflix Socks. A followup to their incredibly elaborate "Switch" that queues up Netflix, dims the lights, silences phones, and orders takeout food, Netflix Socks have a much simpler purpose: to pause Netflix whenever you fall asleep.
If this sounds like something you're interested in, and knitting and Arduinos don't scare you off, then check out Netflix's detailed full build instructions.
Essentially, the socks detect when you're not moving anymore, and send a signal out to your TV or set-top box that will either pause, stop, or turn the device off, whichever suits you best. It also has a built-in way to alert you that it's about to send the signal to your Netflix device, that way you can wiggle your toes or something to prevent it from happening, in case you're still actually binge-watching.
For the knitting, they have templates with designs for your favorite shows, like Bloodline, House of Cards, Daredevil, and Unbreakable Kimmy Schmidt.
As for the electronics, you'll need an Arduino microcontroller, IR LEDs, LED indicator light, accelerometer, battery, felt, and momentary button. You'll also probably want to invest in an IR repeater in case your feet tend to be hidden.
