It’s happened to all late-night Netflix lovers — one minute you’re enjoying your favorite show, the next you’re waking up to a much later episode in the series. If you want to doze off in front of Netflix without missing a scene, there’s a solution for you: a very special pair of socks.

Netflix socks” have an accelerometer that detects when your body is so still that you’re asleep, and a signal is sent to Netflix to stop the program as soon as you’re catching zzzzzs. Netflix says the accelerometer is pretty sensitive, so it will know the difference between when you’re glued to your screen and when you’re sound asleep. But you can also add a pulse sensor to increase accuracy.

The only thing is that, well, you can’t buy the socks. You have to make these special socks yourself. The socks are one of the DIY projects Netflix is showcasing, with step-by-step instructions, at All you need for this project are:

  • Knit socks
  • Arduino microcontroller
  • IR LEDs
  • LED indicator light
  • Battery
  • Momentary button
  • Accelerometer
  • 12” x 12” piece of felt

… and, oh yeah, “an understanding of electronics and microcontroller programming.” So perhaps you might need to get your old engineer buddy on the phone.

It’s hard to say what will happen if you wear the socks while you “Netflix and chill,” but there’s a different DIY project for that anyways.
