You mean I can buy a short precut length of adhesive lined sleeving with a ultra high shrink ratio for only $$FARKHOWMUCH? I have some from RS that I used for cabling, and used a black variety in the military for connectors. Hellerman Tyton also has it in premade variable diameter types with a popular one being a Tee off connection for cabling, along with high voltage ones for cable jointing.

I small repackaging for rubes here.

They actually could be innovative here.

For a regular shrink tube to be effective as a strain relieve you need the lining.
At least they got that right.

But it still does nothing for the bending problem.
The cable would eventually fail just next to the shrink tube, because after shrinking the wall would be thick and stiff on the cable end.
Of course you could get some preformed shrink tube, but that won't help you with existing cables.

What always baffled me you cannot get shrink tube with a thick wall on one end (connector side) and a thin wall at the other end (cable side).
THAT would be innovative.

They've invented the idea of re-packaging adhesive lined heat shrink as something that can be sold as part of the whole "green" bandwagon. They'll probably get a patent for their 'novel' use of existing tech :palm:

The community here should have a contest of which technologies they can repackage and sell.

The trouble with that, is that the application they've come up with is exactly what the product was for in the first place. I might just as well repackage and sell a pencil as a device for writing shopping lists; it would be no more or less original.

If I don't just go buy some (expensive) adhesive-lined heatshrink at Jaycar (AUS)
OR - I cut tiny slivers of hot glue and stuff them inside regular heatshrink along with the wires or parts I'm locking up --- and believe it or not, heating the regulars sleeving makes the glue melt too... even better than lined tubing. - because it runs in between the conductors as well forming a linear water barrier as well!
Don't ask a question if you aren't willing to listen to the answer.

Why do they only show Apple cables? It looks like they are aiming for a specific target audience.
Those apple cables are actually of reasonable quality surviving about a thousand mating cycles. I've "lost" only 1 cable's isolation in the 3 years of my 4S and the cable still works.

It's funny how they've spent "months of work and prototyping", the heatshrink apparently had a long delivery time.

I was told that the quality depatment was on vacation when the new "lightning" cable was made. It breaks. Thank GOD JOBS that there is a chip inside the cable, and no one can copy their piece of copper. But I'm sure this is like alien technology to most people.

I like the detailed camerawork, the actual demonstration of the working product was what sold me on the idea.
The close up photos of the applied product on the cable were the icing on the cake.
I love how nothing is left for the imagination, that is a astoundingly good documentaion!

I'm surprised someone hasn't tried to re-package post-it notes as a revolutionary analog human memory storage system...on Kickstarter.

Thats easy to prevent.
Multilayer thin shrink sleeve with slightly longer lengths on the cable and shorter on top layer to spread the bending moment over a longer section of cable.
I can achieve 5-10x the conductor life on a 4 core flex in this manner.

That's a good very good idea. I also like to top it up with a slightly longer piece of sleeve. This way, the finish is nicer, the underlying sections are covered and their ends will not fray as much.

You mean, people have never heard of heatshrink?

Because the MicroUSB and 30 Pin iphone cables can be purchased at the dollar store.

If anyone is ever concerned about the intellect of "the average consumer", be concerned no more!  It's as low as you could imagine, perhaps lower.

There really must be a lot of people with a lot more disposable income than brain cells to pre-purchase special heat-shrink on Kickstarter (of all places!) when they could just go to buyheatshrink.com (yes, a real site) and get it cheaper and shipped immediately.
It's not always the most popular person who gets the job done.

They are designed to break. Micro USB is as well - it is designed so that either the cable or the plug fails, not the socket. The socket is the expensive part on the expensive device that is hard to replace. The cable is cheap and you can buy a pack of 5 for a couple of bucks on eBay... oh. Well, it's still designed to break.

Of course, no wireless charging because that would defeat the purpose of having a weak cable that costs $$ to replace.

Hm, one thing I do like about Apple is if you bring your failed Apple cable in to them, they will replace it free of charge...

HOW THE HELL THEY COULD RAISE SIX THOUSAND DOLLARS WITH THOSE HEATSHRINK PIECES?!?!?  |O :palm:

This is quite ridiculous. |O

Simple: Excellent marketing. Then again, doing a successful marketing campaign is perhaps not that simple.

See my kickstarter for a tin/lead alloy that melts at (relatively) low temperatures that can be used to make reliable electrical connections.

I'll leave it for further innovators to come up with the lead free version.

I've never seen an apple cable that made it more than few months before the insulation failed at the connector. They're notorious for it. The minimalist aesthetic design provides no strain relief whatsoever.

I'm just about to contribute to someone who has invented a novel electricity conduction device using multiple copper strands enveloped in a cylindrical polymer insulating layer, so your invention is very timely :)

Funny, I've used Apple cables since I got my first iPod in like 2003, and none of my cables have ever failed.  I'm pretty sure I still have my original 30-pin iPod cable from >10 years ago, as well as all of the 30-pin and lightning cables since then, again all of which are still in pristine condition.

Then again, I treat wires and cables properly.  I don't tie them in knots, rip at them from the side, coil them up in 1cm diameter balls, or any other blatant abuse that the average consumer puts their cables through.
