Netflix's new socks can detect when you're dozing and pause the show you're watching.
The concept is admittedly awesome. But these are DIY socks, and you need a relatively good understanding of electronics and computer programming to make them.
For people not comfortable handling micro-controllers and soldering irons, here's our easy guide:
1. Knit or buy a pair of socks.
2. Visit local electronics store.
3. Show them Netflix's 8-step guide and pay them to make the sock sensor.
4. Binge-watch "Narcos" and "Jessica Jones" over the holidays.

Netflix said the sock design was a "DIY project inspired by you."
"Sometimes a show is so good, you just can't stop. And the next thing you know, zzzzz," the streaming service stated on its website.
"Netflix socks detect when you've dozed off and send a signal to your TV, automatically pausing your show. Never again will you binge-watch yourself to sleep, only to wake up two seasons later wondering what happened," it added.
If you've majored in electronics, or know all about LEDs and accelerometers, then you can attempt the steps posted to the Netflix website on Thursday.
The science behind it -- which it says is based on "actigraphy" -- is easy enough to understand.
"An accelerometer detects when you've stopped moving for a prolonged period of time and triggers a signal to your TV that pauses Netflix. When it detects that you've dozed off, an LED light in the cuff of the sock flashes red, warning that the pause signal is about to be sent to your TV. Any motion will stop it from firing," per the website.
The accelerometer is very sensitive to little movements, so it's good at detecting when you're just sitting still, raptly watching Netflix, and when you've actually fallen asleep.
The first suggested step is to knit the socks, and there are a host of Netflix show-themed foot warmer designs you can download from the site. But cracking out the needles and yarn isn't essential.
"If knitting isn't your thing, you can always enlist the help of a knitting-savvy friend or simply use socks you already own," Netflix stated.
You'll then need to build the sensor -- with an Arduino micro controller, IR LEDs, LED indicator light, battery, momentary button, accelerometer and a piece of felt.
The fifth and sixth steps are to build the electronics and set up your IR signals, before you perform a little computer programming.
Lastly, embed the sensor into your sock. Extra hacks include adding a pulse sensor to detect a change in heart rate, which will, in theory, increase its accuracy.
By wearing the socks, Netflix claims you'll be safe in the knowledge that you won't miss a single key scene in your favorite shows. However, if you don't have the time or inclination to make Netflix socks, or go to your electronics store, there is another alternative.
Drink LOTS of coffee. That should help you too. Maybe.
