This looks like something that iOS will incorporate as a native feature. When they do this, do they usually buy the technology? Or the entire company?

Or just clone it and put the company out of business.

Is that really how apple has been working as of late? It's not like they innovate on the software front all the time.

I hope you're joking. If you do plan on doing this then please do it in a suitably strong wire cage, power it on remotely, make sure it is tied down very solidly and make sure nothing you care about (including you, significant others, co-workers, children, pets, possessions etc) is in the plane of rotation because this will fail spectacularly. Keep in mind that if the grinder becomes dislodged or unbalanced that the…

Really great points. I think that when working around power tools it is sometimes forgotten how careful you have to be. Everyone innately knows certain things like "don't stick fingers in light socket" but other things aren't immediately obvious. Perhaps because you are juxtaposing something like an iphone and maybe are focused on the worse case scenario as being a destroyed iphone (in other words the money issue) in…

Crowbars & sledgehammers aren't power tools. It seems much more reasonable to use those without significant PPE.

I want the next "Will It Blend?" to be these people attaching iPhones to a variety of terribly dangerois machinery at high speed. Grinders, chainsaws, motorbike wheels. Or maybe some safer things too - place it on a record on a turntable and film the face of the DJ doing some mixing?

I want the next "Will It Blend?" to actually answer the stated question — "can this iPhone be used to make a smoothie?" — rather than "can it be blend ED ?". Seems like strapping an iPhone to an angle grinder is getting close to answering the stated question...

I found this to be really incredible. That is some amazing video stabilization technology. If this app was available for android I think I would use it for every video capture I ever do.

This is one of the developers of the app. The Android version will be available in the following month. We are planning on running the experiment on Android devices too!

I've done quite a bit of work doing stabilization on Android. I think you'll find the Camera APIs quite lacking. Are you doing image based stabilization or using sensors? The fact you mention the gravity sensor tells me you're using sensors.

Let me know, I'll be glad to help how I can.

Hah.

Wait until you get a nice long steel nail that jumps away on you from the crowbar just as it exits the wood and embeds itself 2" deep in another piece of wood. if you're lucky.

Or when a sledge hits a really hard pebble just off the side of a solid wall and it gets catapulted out.

Sledges, crowbars and pickaxes are really dangerous tools and especially if you should wear goggles at a minimum, and probably a helmet too.

And, no, I'm not from the cradle to the grave coddling department.

Have you never used a small 11k angle grinder? Those things try to jump out of your hand even worse than the big 6k RPM ones (without soft-start, of course).

I have used a 11k RPM grinder, not that I would have called it small the thing was like 10 pounds. So, I can can see how they might be harder control with newer motors and swapping steal for plastic. Backing up, being safe with power tools is IMO more a mindset than a set of safety equipment. As such you need some understanding of the forces involved. Not, just to be safe right then but so you don't get lulled into a…

You have absolutely no idea what an unbalance of even a few grams will do at those rotational speeds. The thing will escape your grip even if you're quite strong if you're not holding it very tightly.

No, I mean "can this iPhone be used to make a smoothie", not "can a blender turn this iPhone into an iPhone smoothie".

Take a blender, remove the blades, put iPhones on the spindle where the blades were. Now fire up the blender and throw in some fruits. Will iPhones spinning at $whatever RPMs be able to turn your fruits and wheat grass into a delicious smoothie?

The original is actually "Will It Be Blended [by this blender]". I want to know "Will It Make a Suitable Replacement for a Blender".

11k RPM is not as fast as you might think. That 660,000 RPH * ~8 inch diamiter circle. So outer edge is 3.14*8inch/12/5280 ~= .0004 miles per revolution or 260MPH. But the center is stationary so actual force is a little less than you can throw it. Edit: Camera is not centered on the iPhone. So if you center the camera it's worse than that. I would personally not stand anywhere near it.

The very fastest fastballs are ~100 MPH. So 260 is not 'a little less than you can throw it', what will happen is that it will get dislodged on one corner, do a partial spin and then come flying at you (if it doesn't break up before that).

I'd really hate to be hit with anything at 260 MPH, especially not with a phone. Those things are hard!

Yeah I really don't understand the parent making that comment either. As if it's so much work to have some safety gear on.

From busting apart shipping crates as a kid I also realized that in addition to the goggles and helmet you also need boots that can take stepping on a stray nail as well. Not sneakers, definitely not sneakers.

Absolutely blown away with the demo video (centripetal issues aside) though annoyingly I'm one of those 'other' users, so I have to ask: Anything android related in the pipeline?

"This is one of the developers of the app. The Android version will be available in the following month. We are planning on running the experiment on Android devices too!" - OP.

Absolutely immense -will keep my eyes peeled =D
