Nixie: Wearable Camera That Can Fly

My_design says...

The slap bands don't work because the arms are at angles to each other. Slap bands can only rotate in a straight direction (They are basically tape measure metal), so they wouldn't be able to come back to meet in the center like they illustrate. Also they have the motors all prettily lined up and facing directly off the wrist, that would require the material to be able to twist.

For the rotor size, these are fixed pitch rotors. You can change the pitch of the rotor to give you different flight characteristics and in general you have to match the pitch to the motor to be the most efficient. I may have this reversed, but a lower pitch prop gives you more torque and less overall speed, but a higher pitch prop gives more top speed, less torque. Making a prop that can be injection molded at that size that even works is difficult, making one that is super efficient would be even more so. QC would have to be incredibly exacting. As a gauge, the 2" x 2" quad has 1" props. They can lift it and buzz it around pretty well. Those things were a pain to get correct and I have a hard time imagining anyone making them more efficient than they are. In the case of the 2" quad, we didn't even paint the body because we want to limit the impact on flight time from added weight. All molded in color. That's how sensitive these things can be. There are better motors if you are willing to pay, but even then it may not be enough.
Go Pro records in HD, but doesn't actually broadcast anything (plus it is big enough to keep this thing from flying anywhere). If you want to broadcast video you have to do it in 640x480 tops. To do that you need something like an FPV system that broadcasts on a spread spectrum. If you went bluetooth you have an effect range that is pretty small. Wifi requires more power to get a longer range. A video transmitter system would require a separate device to attach to your phone to receive the signal and translate it to a PPM signal for through the headphone jack. But a VTX is pretty heavy as well.
And things may drain just a little bit of power, but it stacks up. At most you have a 250mAh Lipo battery that can fit in there. That isn't going to buy you a bunch of flight/video time.
Video on the phone is going to be subject to interference, so you would want to record on the quad. this would get you HD quality, but also adds weight, which means more battery draw, which means less flight time.

I don't understand, why would they have to bend in multiple directions? it seems they need to be straight or curve in one direction. Did I miss something?
I'm estimating the size, about 6" around one's wrist makes it 6" 'wide', and near 3" 'long'...yes the blades seem about 1.25" diameter. You would know more than I about that being enough, but I do know there are different prop configurations for different applications, perhaps they have an ultra efficient prop and motor pair? There are certainly more powerful motors available, if you're willing to pay for them.
Adding blue tooth is minimal in weight and power drain, and the lag shouldn't be an issue in most applications (I wouldn't try making it run a gauntlet of obstacles though).
Camera batteries are pretty powerful today, allow fast drain, and come in small sizes. Maybe not enough yet, commercially available, but certainly possible to make...if you're willing to pay.

For your issues....
1)super thin spring steel could work, but wouldn't look like the plastic they showed. What's the issue with 'slap bands'? They seem perfect.
2) power is an issue, as is flight time. I feel like early adopters would sacrifice flight/record time for the advantage of size...but only time will tell.
3) object avoidance IS an issue. Likely the solution is to limit it to use where there's no obstruction above it and not too much in front. Slight lag isn't an issue, if it's not moving fast. Return to the object it's centered on should be no problem, it tracks an object to film it, it shouldn't be too hard to return to it. Now, catching it while hanging on a cliff....yeah...that's tough.
4)Does not Go-pro already wirelessly send it's video in real time "HD"? They cost under $400.

I'll agree with you, you would be MUCH better off buying a larger one that works NOW instead of sending money in hopes they come out with this super miniature one. That said, I still think this is possible...just expensive and difficult to make work.

Nixie: Wearable Camera That Can Fly

Yeah there are slap bands out there, but they don't work like this is presented to work. The arms would have to bend in multiple dimensions, and then straighten out and be able to provide a stable flying platform. The closest thing I think of for doing something like that is the "bendy" character toys where the metal wire is co-molded inside the body. That is a very heavy solution.
I misspoke on the 2" square, it is 2" x 2", so 4" square. I'm not sure that I agree that theirs is 6" x 3", but even if it is that would mean that the prop size would have to be about 1.25" and that doesn't work for a 6" x 3" vehicle. There isn't enough thrust and the motors at that size don't provide enough RPM's for that kind of weight.
On the electronic side, they show it connecting to a smart phone with video feedback. That means you have to have bluetooth at least, or a 5.4ghz video system if you want more than 30' range. or it has to have a Wifi TX on it. All of those thing require power. Sure it could analyze the video signal to determine subject matter, and provide guidance but you have some very serious issues there. If you do it on board it requires some processor power (More drain), if you do it on the smart phone app it will create lag.
Your phone has over 1,000 mAh in it (1440 in Iphone 5), that is a TON (4-10x) more than what this thing would have. Battery technology may be a big research project right now, but there isn't anything on the horizon that will get them to where they need to be. Most of the tech research is in sub 1C rated batteries for things like full size cars. Something like this needs a 10C rating minimum if not a 20C rating. Unfortunately most of the upcoming technology can not handle drains that fast. Things tend to go "Boom!". When you do something small, and even 6" x 3" is small, you have very serious power vs weight issues. It all comes down to issues of power density, and nothing exists today that will give it to them as they would need..

So right now these guys need to figure out:
1) A new light weight material that can lock rigid but also bend as needed in multiple directions.
2) A new battery technology that allows them to get the power they need, for a 6 axis gyro, 4 motors, control board,a RX, a HD camera and some sort of VTX while reducing weight. How long it powers all of that would be open, but if it is under 10 minutes I think people would be a little disgruntled. Right now people are wanting the video quads to get about 30-45 minutes of flight time on the 5200+mAh batteries.
3) Write code that allows them to analyze video in real time so as to provide object tracking and avoidance without lag while capable of running on a smartphone. It would also need to return to home when the battery runs low. That would be a little tricky on a cliff face, or if you are riding a bike through a forest. Another issue is that they tilt the camera down, they don't say if this is actuated, or done by hand, but it could lead to serious issues with programming object avoidance if you can't see anything above you.
4) Since they show the image as HD on the phone screen, they would also need to come up with a new way to broadcast HD video wirelessly. Right now that system costs $40K and is rather large.

All in all it is a dream product that people are going to get suckered into funding it. Some tech may come out of it that could be monetized, but I don't see the item coming out in this format, at least not in the next 3-5 years. You'd be better off going with AirDog.

Well, perhaps with currently available public domain parts, it's not possible. That doesn't mean it's completely impossible.
The flexible frame might be hard, but there ARE already wristbands that un-bend to make a flat device, they've been around for decades, I recall seeing one in the 90's. Making it support flight might be hard, but not impossible, especially with the small forces this thing provides.
You say there are already 2" square quads out there, this was closer to 18"square(6"X3"), so the 'it's just too small' argument falls flat.
Battery time might be a factor, but a 5 min video is pretty good for now, plenty to prove the concept. Also, battery life is increasing fast.
The camera and GPS in a phone hardly uses any battery power too. These tiny devices are really not hungry enough to make them a power drain problem, at worst they might limit flight time slightly. Also, there's no GPS needed really, it could operate by keeping the subject in frame at approximately the same distance...then it could just follow you through the trees, using the image to avoid obstacles. It would take some computing power, but not an outrageous amount. Perhaps it's paired with a cell phone to do the computing? That part wouldn't be hard.
Again, because the tech isn't available on the market today (and I'm not at all sure that's correct) doesn't mean the tech isn't available to some, or creatable by intelligent people. I just don't see this as that far away.

The Daily Show: Glass Half Empty

Fairbs says...

It seems like the bluetooth ear piece wearers have realized how stupid they look and how shallow walking around like a self important arse is. Now it's down to the 1% d-baggers that still wear them. I predict the same course for this product.

The 'every one will be wearing them in a year' comment is so smug. Really irritating.

How fast will the Russian Hackers takedown the tourists?

spawnflagger says...

really need more details about this... When they had brand new devices, does that mean they were un-patched for known security holes? Or are all these exploits the Russians use unknown, and there are currently no patches, such that a completely patched/updated device is still vulnerable?

Any WiFi captive-portal "login" page could inject known browser exploits into the html - If you use your own MyFi (personal hotspot), and are willing to pay huge for roaming international data, then this form of attack isn't possible.

And the coffee shop owner probably doesn't know that their wireless access point is serving up malicious code. It was either hacked by who they bought it from, or whoever installed it, or by some hacker who went to the shop. But shame on the airport's IT security - if they have official WiFi that was also hacked. (but the criminals might have set up their own wireless and called it "Free Airport WiFi")

Every OS on every device (not just Windows) has security holes, Mac OS X included. The hole gets exploited to allow running some piece of software that the user didn't intend, and that software (malware/virus) collects user data and uploads it back to the criminals servers on the network (these 'data collection' servers are also usually attacked/compromised computers, so they can't be traced directly back to the criminals).

My advice to tourists would be to bring a "dumb" phone for voice calls. (keep bluetooth turned off though) Then you'll remember how great it was to only charge it once a week

Richard Sherman makes second best commercial ever

spawnflagger says...

Beats are made by Monster - the same people who make way-overpriced HDMI and audio cables.
They have successfully capitalized on the human psychology logic fail of "It costs more, so it must be better."

coincidentally - today's woot - $99 Klipsch bluetooth that probably sound better.

Blackphone introduction

Sniper007 says...

Give me a smartphone that can record both sides of the conversation to your phone's memory (WITHOUT using the speakerphone function) and I'm sold. In particular, I'd like to record a conversation I'm having on a bluetooth headset. It can't be done as far as I know.

2013 Tesla Model S Door Handles

I think it automatically unlocks when it detects transponder or bluetooth dongle nearby.
It' doesn't open just for anybody.

Wouldn't this encourage random strangers to try and open the door? What if you actually left the door unlocked?

How it Feels (through Glass)

xxovercastxx says...

@Deano

The sad thing is it looks like you're right about the phone calls which I think is a major mistake. It was confirmed today that Glass will tether to Android/iOS for 3G/4G data. That pretty much ends my interest in owning Glass.

I think excluding phone hardware from Glass is insanely stupid, but given that's the reality, I can't argue against the importance of integration anymore.

Hopefully in a few years they will truly integrate them into a single piece of hardware and then we will have a piece of hardware which might be worth buying. If Glass is just to be a glorified Bluetooth headset, I'd rather have contacts.

The Washable Keyboard

Reefie says...

>> ^volumptuous:

You can do this with most keyboards anyway. They just don't have the drainage/air holes that this one does. But even Apple's fancy aluminum bluetooth keyboards, toss them into the dishwasher, let it dry for a day, and everything's fine.


Heh I was all set to state how most electronics are washable, but you beat me to it The key part is the drying! Used to recondition washing machines and other domestic appliances, the control boards would always have a soapy residue covering them after a few years of use so we'd pull the boards, dunk them in a bucket of fairly hot water and then leave them out to dry before plugging them back into the washing machines.

A Really Dumb Invention??

xxovercastxx says...

>> ^spawnflagger:

I like the idea, but didn't he do a simple product search ?
or hell, even the domain itself - http://www.gojo.com/ . It's a brand of hand cleaner (good stuff too) that's been around for years.
I don't see how he isn't infringing on the brand/trademark "gojo", so a lot of legal battles ahead...
Oh, and lastly - cancer. Do you want a high-powered cell phone transmitter next to your brain, or a low powered bluetooth headset?


Trademarks are only supposed to protect against similar products. It would be trademark infringement to make another soap or cleanser and call it Gojo. A shampoo would probably be considered too similar; maybe something cleaning-related like a sponge or scrubbing brush, too. A headband with a suction cup is not in the same market so it shouldn't be in violation.

The microwaves that are emitted by a cell phone are non-ionizing and thus, not linked to cancer. They're in the same carcinogen group (2B) as coffee and pickles.

And how would it be possible to put that on using only 1 hand while driving?
or does he expect you to have phone tied to your head the entire time driving, even if not on a phone call ?
