The simple, clever sensor behind automatic windshield wipers

When it's wet it wipes.

The thing that surprises me the most about this entire episode is that Alec is not the kind of person to read his owner's manual front to back within the first 30 days of buying his car.

[norlockv]

Alec, stand proudly. You used the manual as intended; as the last resort. You sir, are an engineer.

[SueBobChicVid]

I watched a Technology Connections video, in its entirety, in one sitting, and still had time for my life. Who knew that was possible?

[PopsGG]

As a Tesla owner, thank for the first 50 seconds of this video and 8:50. A much needed roasting of Tesla's decision to not include them.

"Look, I get it wet, and the car wipes! But two can play at that game-" then using a screen whipe as a transition between frames. Is exactly the kind of joke I love getting blindsighted by between detailed information in a presentable manner, and truely midwestern levels of snark.

Some engineer:
- looks at pulse oximeter
- looks at windshield
- *squints eyes*

What you try to look up: Change wiper blades
Owner's manual index term: Inclement weather clearing system maintenance

One thing I love about technology connections is that he only posts videos when he has something to say. Keeps it exciting when a new video comes out!

[SpikerStudios]

This video was so quick, I didn't even expect to be showered with new Alec rant time

I know you do the low effort videos for yourself, but I would like to remind you, we all watched an hour long video about dishwashers and loved it. I still, to this day, get the hot water flowing to my sink before starting the dishwasher add soap on the door because it doesn't have a place for first stage soap. We love your shit, bro.

7:24 "having two of them"
Alec, please never stop doing these it's hilarious

Electrical engineer here. Industrial electronics, automation and control systems specifically… love watching your channel and completely share interest in the same topics. I have fond memories as a child having battery powered toys and electronics and being fascinated by how they functioned. My favourite was when they broke or stopped working properly so i could disassemble them and see how everything was designed and functioned. Keep it up and god bless

You have no idea how amazing this video is for me. One day, I wanted to know how this worked on my car, but when I googled “how do rain sensing wipers work” I just kept getting pointed to manufacturer webpages that just say “automatically detects rain and activates wipers” without anything saying HOW it detects rain. It’s bothered me ever since. Thank you!

[notadamkhan]

this is a great first technology connections video i can show people. short and sweet but has all the sass, edge, and juice of a full video

I once had the privilege of working along side a Technical Author and he worked really hard to create a useable, easy to understand users' manual. He did comment that the manual would only be as good as the information that we (the Engineering Team) provided and the amount of time we were prepared to spend answering his questions. It always struck me as a bit of a shame that he didn't get to put his name on the manual that the customers got to read.

I had two very nice surprises recently after buying a very cheap Citroën from 1998. First, it has a rain sensor. And second, It´s by far the best working rain sensor i have ever seen. It never gets confused or start when it´s dry or forget to wipe when it´s wet. It´s 100% perfect all the time. And they did that in 1998!

As a Tesla Model X owner, I appreciate all the little jabs at Tesla.

[alexrogers]

Bro "low effort"? This is the perfect amount of effort, I learned everything I wanted to know about the topic and finished the video!

[itsamindgame]

It is highly satisfying to see you present a technology that relies on the magic of having two of them.

[chameleongirl]

I did. I read the whole manual.
I also read all the announcements my work makes, the instructions for any electronic item I've purchased (even if it's just a basic toaster), and the newsletter that my local council puts out.

Some days I'm almost convinced I'm not autistic. Until the next time I do something others consider out of the ordinary.

I like knowing things! 😅

Which is why I like your videos, they're always fascinating.
