Nixie: Wearable Camera That Can Fly

My_design says...

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.

VideoSift 5.0 Launch! (Sift Talk Post)

Hybrid says...

Yeah, not a fan of the new promoted videos system AT ALL.

1. They aren't visible enough - your eyes are drawn to the bigger, unpromoted videos below.
2. You can waste powerpoints if three other videos are promoted straight after you promote something... and lets face it, in the evenings, the vs 4.0 front page occasionally had 10 promoted videos. So this will happen.

Something needs to change here. This is more than just "getting used to the change".

This is not a piano. It's an electronic keyboard. If it has a plug it is NOT a piano.>> ^harpom:
Excellent, amazing and brilliant. I love how the song translates to the piano so well.
Chop Suey is a hard kick ass song, yet it plays so well on the piano. Sounds like a cross between Mozart and Beethoven.


LOL. Whatever. The instrument is made to sound like a piano. Sad that you have to go through life taking everything so seriously.

Everyone has their pet peeves, mine is calling pieces of music songs (which she actually does). When people are raised with a musical background minor things like that are just little quirks that make us who we are.

See response to conan. Also last time i looked Chop Suey was a song by SOTD.

And when it's played on piano without anyone singing, it has no words. When it has no words, it's not a song.

Again lol. Don't try and tell me when you listened to the song you were not hearing the lyrics in your head.

System Of A Down - Toxicity - Piano Cover

>> ^KnivesOut:
If she played on an acoustic piano, that would shut them up for sure.
Or spoke, even.



Once someone's got the skepticism, few things will be considered convincing evidence.
"Oh, the clock can be programmed to tick slowly. The fingers don't blur right. She doesn't speak. She only plays on electric keyboards. Her hair moves unnaturally. Look at the way her boobs bounce. Mmm...boobies."
