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.

I Can't Take my Eyes off this Hula Hoop

spoco2 says...

I'm upvoting the light display... seriously, that's some awesome patterns and shapes being made there.

I'd love to see a nicely shot, HD video in a good location with a hula hoop like this would be cool

Tellingly on the auto-tune front @TheSluiceGate, @LukinStone, I asked on the youtube video of this whether it was used, and they have moderation turned on... well, they haven't put up my question or an answer, yet have put up others that have come through since.

Also, there's a fan who set up a page at 'ragtube' (never heard of it before), which seems to have his old youtube channel description on it:

Mike's setup:

Martin DC-16RGTE Aura 6-string guitar, Guild F-512 12-string guitar, into Yamaha 01x into HP laptop (via firewire) running Cubase 3. Mike's vocal mic is a Neumann KMS105.

Jeff's setup:

Fender 5 string Jazz Bass (Mexico) into Universal Audio LA-610 Pre amp/compressor
Jeff's vocal mic is a Neumann KMS104.

The audio is recorded dry, then mixed in Cubase 6, using mostly UAD-2 plug-ins. No Auto-Tune is used (since people occasionally ask). The audio mix is then synced to the video in Sony Vegas. The video camera is a Canon Vixia HF100 (for the more recent HD videos)


And now his youtube page says nothing about autotune... so did they start to use it, when they didn't previously, or have they always and been caught out on it, so have stopped claiming they don't?

Seems fishy to have had the info up, and now not.

Post Office Anti-Email Attack Ads

Some forms of communication.

Mail - Been around forever. People used to work on handwriting skills because having someone else being able to read what you wrote was considered a good thing. Nothing said F you like a Dear john letter. "Dear John, By the time you get this I will have slept with half your friends and everyone on main street". A tree Died for your words.

Telegram - Defunct - Faster over long distance. Everyone in the telegraph office got to read it before you did. Thanks to "charge per word" What had to be said was condensed. "Dear John. stop. By the time you read this i will have slept with someone in the telegraph office. Stop." The word "Stop" becomes a punch line. A tree still died for your words.

Telephone - Much Faster- Now you could speak to someone across the street with out having to step outside. Dear john letters still used but now the option to call it off could be done instantly. "Hello John, The guy you hear making all the noise is Mark." A tree still died. They had to hang the wire somewhere.

Email - Slower than the phone but could be less personable. Now you could send Video and picture along with the email. Dear john email become popular with added HD video or pictures. "Hey john, Let me introduce you to the starting line for the Denver Broncos. If you had read some of the spam I forwarded to you. This could of been avoided." The guy in IT has already posted the video online.

Videosift needs an HD channel (User Poll by Farhad2000)

Farhad2000 says...

As I said in my initial post - "HD videos in one channel must be legit sources and video since copyright HD stuff would be pulled."

>> ^SlipperyPete:

I can see this being somewhat problematic. If an HD vid goes dead, and is replaced by something non-HD... thus my 'perhaps' vote.

Steve Jobs announces the iPad

Croccydile says...

I guess I'm late to this party, but I'm also glad to see some Apple sensibility here for once.

I really do not get how Jobs disses netbooks and then introduces something that is almost twice the price with half the usefulness. I know half the Apple user crowd will buy this anyways, but I guess I will take solace that my netbook easily fits in a carry bag.

My mum has one of those Asus eeePC's as well and despite being a technophobe she absolutely adores it. It's not about how fancy it looks or what it is capable of, its about how goddamn convenient it can be. That is why netbooks stormed the industry despite the fact they have barely been out two years now!

A $329 netbook can get 10 hours of battery life, has a built in camera + microphone, usb ports for removable storage, built in memory card reader for MORE removable storage, physical keyboard, can do more than one thing at a time, run flash... and hell the latest ones can even decode HD video with that nVidia ION stuff.

The iPad just looks like an iPod touch for old people... think about those large sized remote controls.
