Thumbs Up

A camera on the back is a great idea. The first time I noticed that option was on the 2011 Kia Sorento. It's particulalry important since so many vehicles are so big. Use of the Ethernet to transmit data sounds like a good advance. Fixing wiring in cars can be a nightmare.

Ethernet everywhere

Another recent deployment of Ethernet is at concerts. Paul MacCartney was an early adopter a few years ago, running the sound signals from the stage to the sound board. Now it's being used in theaters as well as at concerts. The benefit is improved network confirguration and lower installation costs.

I have to say, I'm not a big proponent of the camera on the back. I have one on my Acura MDX and I never use it. Perhaps it's the male/female thing, but I, for one, don't trust and can't visualize pulling out without turning my head to see where I'm going. Drives my husband nuts because he can't understand why. Now the cameras for automatic parallel parking--that might be whole other story!

Cutting down on the number of protocols is a good thing.  I love the idea of Ethernet in the car.

But are RJ45 connectors really the way of the future?  It's assuredly not industrial (how many of you are working with broken-tabbed RJ45 connectors friction-fit into your computers right now?).

Is the industrial M12 Code-D connector the way?  Or is there a happy medium between the two?

TJ - Nothing saying that we have to use the plastic RJ-45 connectors going forward.  I used to work in the off-road industry that used networks on a much larger scale but essentially the same idea mentioned here (control on one type; info on another).  We used metal RJ-45's from Siemens with the clip being a spring-like device.  If the link works, this should be a picture (found with just a google image search):

There are numerous metal-shelled versions of the RJ45, but that doesn't make them an industrial connector.  It was never intended to take strain, or resist vibration, or exclude the environment.

In the uncontrolled environment that a car experiences, I'd like to see something more robust, more industrial.  Otherwise, I see flaky data connections plaguing car owners for the life of the car.

Here are two very recent "Made By Monkeys" articles pertaining to cars:

Monkeys Made the Rain Trough on My Van

Monkeys Designed My Jeep's Stereo Wiring

 

They show the possibilities that poor design of the physical network could bring; RJ45 connectors will not hold up to water pouring on them or being constantly flexed.

Samsung's Galaxy line of smartphones used to fare quite well in the repairability department, but last year's flagship S5 model took a tumble, scoring a meh-inducing 5/10. Will the newly redesigned S6 lead us back into star-studded territory, or will we sink further into the depths of a repairability black hole?

In 2003, the world contained just over 500 million Internet-connected devices. By 2010, this figure had risen to 12.5 billion connected objects, almost six devices per individual with access to the Internet. Now, as we move into 2015, the number of connected 'things' is expected to reach 25 billion, ultimately edging toward 50 billion by the end of the decade.
NASA engineer Brian Trease studied abroad in Japan as a high school student and used to fold fast-food wrappers into cranes using origami techniques he learned in library books. Inspired by this, he began to imagine that origami could be applied to building spacecraft components, particularly solar panels that could one day send solar power from space to be used on earth.
