If your project is suspended on KS do you still the ability to message all the backers or post updates? i.e. point them to the IGG campaign?
Pretty sure they can't post updates, as I've seen a few get suspended and never any updates.
Their account isn't suspended so they can still post comments, and they can possibly send individual messages to backers (i.e. one at a time), but again I'm pretty sure they can't do bulk messaging.

"[Indiegogo] have been incredibly helpful & they believe in the Skarp Razor as much as we do," Skarp said on its Facebook page.

So Indiegogo courted them perhaps?

Almost certainly!  I've been involved in a Kickstarter, and as soon as IGG got a whiff of the fact we were about to launch they were all over us trying to get us to switch to their platform.

EDIT:

This just proves that you can't keep people from spending their money on this stuff. What will their KS backers do? Blindly follow them to IGG and get back up to $4 million, or take this chance opportunity to re-evaluate their foolishness? It's just starting to get interesting. :popcorn:

How soon until they say the multi-billion dollar shaving industry was responsible for getting them booted off KS?

The have a new demo video:


I'm know this is only a prototype but with this speed of shaving you would have to wake up two hours earlier to shave. ;D

Now if they could market this as a genital and anal shaving tool, they might have something...  :-DD

I think from the demo videos and the technical descriptions that there's no doubt that light energy can be used to fragment hair shafts.
But there is a lot more involved with a simple task like "shaving" than that. When using a razor blade, the blade is made very thin not for sharpness, but for flexibility. It bends to conform to the surface of the skin so that you can easily shave a curved skin surface. The lather made from soap is a water emulsion with lubricating and load-bearing properties so the blade can glide over the skin surface evenly without digging in.
I see no attention to this detail in the SKARP campaign at all.

Forget Laser.... What about this:

http://www.instructables.com/id/Fire-Shaving/



Somebody get photoshop and combine this image:



... With this....



Then we can have little flames coming out the end of the Skarp... Handle will contain butane refillable chamber and you "turn" the end (or click a button on the end like a pen) to spark it into action. Ok IndieGogo... here I come! :-DD


This guy has the right idea... Look how fast those hairy legs become super smooth with a blow-torch....

Why does anyone support this project again after watching the last video? It might be possible in theory, but as helius wrote, there are lots of details and doesn't look like they know them. Would need some years more research for a product which is as good as a traditional razor.

Nobody with a sane mind would want to risk his eyesight even if shaving with a laser would work as good as or better than traditional ways.
Then again, this probably goes to show that a good share of humankind is simply a bunch of idiots.

Is it me only seeing a small hot wire as a razor? So the guy is trying to avoid touching it to his skin? Seems like not laser at all. The other thing is that the wire seems to be hot after touching the hair, so you can see it glowing.

It is a glass optic fiber suspended across which forms the blade "edge". When light enters a fiber like this it bounces off the internal walls and travels along the glass fiber without exiting... Otherwise you would have all your light escaping out the sides very quickly.

It just so happens that when you have AIR and GLASS interface, the incident angle for a beam to hit the inner side of the glass/air interface has to be greater than some angle for the light to pass through. Otherwise almost all of it gets reflected back. But as soon as you change the materials that make up the interface (say make it GLASS/GLASS) the light can pass right through.

Imagine you have a piece of GLASS with light inside. It is surrounded by AIR. Light hits the inner wall of the glass (to try and escape) and bounces off. Because the GLASS/AIR interface requires a larger angle to escape than what the light hit at.

Now put another piece of GLASS up against the first GLASS with light in it. As far as the light is concerned, it has no idea it left one piece of glass and went into another. If there is no air space between them, the light thinks it is in the same piece of GLASS and will leave the first piece and enter the second piece at pretty much the same angle.

This is all basic stuff about reflection, refraction and what's called the critical angle.

Anyways, the "Skarp" works because when HAIR touches GLASS, the light is no longer interfacing a GLASS/AIR interface (which causes the critical angle to be such that light bounces back into the glass fiber). When you have GLASS/HAIR interface, the critical angle changes so that the light can now escape and travel through the hair, causing it to burn to a crisp.

That's the idea behind the technology. It is nice in theory, but will take WAY WAY more refinement for it to work. For one, they need to create a SOLID FIBER channel rigidly kept in place and not a thin piece suspended in thin air which will easily break. Also, it will need to bend a little to allow some flex over curved skin surfaces. It will also perhaps need some forced-air to come out the tip to blow away the hair as it cuts, so it doesn't "fuse" back and just dangle half-cut like it shows in the video.

Anyways, LOTS of refinement is needed... They are going to burn through that $4 million fast.

But how do you get close to the skin without coupling into the skin?

OK, now this is interesting... it seems that people from Indiegogo are now reading this thread.  I base this on the fact that just last night I mentioned in an earlier comment here about IGG courting our project [1] that was about to launch on KS, trying to get us to launch on their platform instead.  That was nearly 3 years ago, and I never dealt with IGG directly then or since as I was the "tech guy", and others were doing the "biz stuff".

And all of a sudden I receive a Linkedin message from someone at Indiegogo overnight...

I hope this finds you well. I am a crowdfunding specialist with Indiegogo and was interested in discussing a potential large volume campaign with us for the Light product you helped develop.

We've supported various Australian businesses in reaching the US and would like to extend the same efforts for the Light. Are you still involved with this project?

This is a classic example of how IGG really should have some liability for the campaigns on their platform.

This is another reason why the Skarp isn't practical - it can't possibly provide a close shave.

A star wars version which detected where the hair was and pew pew'd them with a converging beam just below the skin could provide the closest shave ever ;)
