Wait, a quad underflip 1620 should be 4 back flips with 4 1/2 complete spins, shouldn't it? This was just a quad underflip. Impressive, but not as described.

Place I go to gives 2 pre-rolleds for 5 bucks, and they donate to charity so I would have twice as many joints as this guy and have contributed to ailing humans. (Or 25-50 for an 1/8, so I could have a quad for that same price.)

Hey, now Videosift is a source for weed prices.

$750 quad and you live next to what looks like a trash heap.
Nice.

Shouts & Murmurs February 16, 2015 Issue
Diary of the Left Shark
By Kelly Stout




A remarkable feat of agility was performed on Sunday night, and it had nothing to do with football. It was the sharks. . . . The dancing sharks at Katy Perry’s Super Bowl halftime show . . . danced in unison. But soon, one of the sharks, specifically Left Shark, said enough of that, and began to do his own thing frenetically on national television.

—Washington Post.

First rehearsal went great. Katy says to just call her “Katy”—very down-to-earth move. Happy to see Eric! Grateful he got me this gig, as not a lot of work out there for us sharks.

Second rehearsal O.K. Eric picking up dance moves faster than me, which is no biggie, since I’m still getting over quad injury. Still, resolving to work harder. Went for a beer afterward with dancing Blue Surfboard, named Jeremy. He’s worked with Miley Cyrus!

Eric texted wanting to know if I could use some “extra practice.” Didn’t think I needed “extra practice,” but Eric = good buddy, so I value his input. Couldn’t meet him, though, had book club.

Eric acting high and mighty in rehearsal—keeps referring to himself as “old veteran.” Feel he should turn it down a notch. Super Bowl halftime show is not a combat situation, and metaphor makes no sense.

Rehearsal rough tonight. Eric called my grasp of choreography “amateurish.” Said he did big favor by recommending me, and now worried Katy won’t hire him again. Said work must be “on a professional level” with “zero tolerance for mistakes.” I told him I was sorry to have disappointed, that my work will be “professional level” from here on out. Went to bathroom and cried into fins, but no one saw except Jeremy, who was very understanding. J says Katy makes a lot of people crazy—just ask Russell Brand! Found joke to be a little sexist—and, besides, Katy not really the problem—but appreciated support.

Katy took me aside after rehearsal. Uh-oh. But no! Said she likes seeing my extra effort! On verge of major breakthrough vis-à-vis choreography!

Happy to have long weekend off from rehearsal to regroup. Guy at brunch overheard me talking about current gig and asked if I am a real shark! Of course I’m a real shark! Tried not to be offended, but people can be so ignorant.

Back at rehearsal. Things steadily better, but sometimes feel Eric = competitive with me, since so few of us sharks in the industry. But shouldn’t that bring us closer? (Rising tide lifts all sharks!)

Big day almost here. Grandma and Mom both called to say everyone back home’s rooting for me. Pressure, but in a good way.

Eric recommended some changes to choreography today. Katy considers Eric “genius,” so took recommendations. Feel my success with old choreography hard won, so am disappointed. This time, Eric didn’t offer any “extra help.”

More dance changes today! Can’t keep up, and Eric can tell. Hate to sound paranoid, but worry that Eric’s trying to sabotage me! Going to have a glass of Shiraz to relax before practicing new moves.

Regret drinking entire bottle of wine last night. Skipped rehearsal, which I realize is not “professional level” behavior, but Eric and his “zero-tolerance policy” can suck it.

Embarrassed by last diary entry. Eric is not sabotaging me. Am letting my insecurities get in way of friendship.

NOPE. ERIC’S DEFINITELY TRYING TO SABOTAGE ME. Super Bowl is tomorrow and he changed dance moves AGAIN. Trying to make a fool of me. Unsure which makes me sadder, potential end of dance career or potential end of friendship.

Super Bowl over. Grandma and Mom called to remind me that my personal best was all they ever asked for. Am laughingstock of Internet. Gained hundreds of Twitter followers, but suspect most are “joke” follows. Katy sweet about it.

Jeremy invited me to have a beer with him and other Surfboard. Frankly, feel that other Surfboard’s kind of a blowhard, so declined.

Got voice mail from Mom this morning asking if I’m considering going back for teaching degree. Said I’m “good with kids” and not end of world that dancing didn’t work out. Ouch.

Jeremy brought over falafel last night and made me forget Super Bowl debacle with impression of Taylor Swift. Didn’t know Jeremy = T.S. fan! Promised I wouldn’t tell Katy. Not that I’ll be working with Katy again anytime soon.

Text from Eric wanting to know how I’m “holding up.” Chose not to say anything, as had nothing nice to say.

Jeremy joining book club! Silver lining of Super Bowl ordeal.

Downloaded application to Columbia Teachers College. Think I could maybe make a difference in lives of youth, plus get mind off Super Bowl. Jeremy, Mom, and Grandma all supportive. Mom asked if Jeremy just a friend or what. Her ideas re male friendship pretty “stone age,” but appreciate her interest.

Feeling O.K. about future. Dance world maybe too toxic for shark like me. Perhaps whole episode not humiliation but wake-up call! Considering move to Austin. ♦

Roman candles aren't guns.
My brother thought of this in the early 80's with his RC plane, and used it to abuse me more than once. Lucky me they didn't have quads then.

Do a search on the Proto X or Syncro from Estes. They are great little quads.The Crazyfly doesn't support FPV, they have a small programmable quad (Which is quite an achievement BTW, not to downplay what they have done, and the multiple features make it a pretty cool little platform). But Is not really all that close to the Pixie. They removed all of the plastic from a #19 Keychain FOB Camera(You can find them all over Ebay) to save weight and are placing it on top, it can only record and not broadcast, hence no FPV as shown on the Nixie. The induction charging is very cool, and I don't know much about it but it seems like that would take a long time.
A gauntlet is a much better solution IMO than what Pixie is showing. It can then be used as a home location as well as something for the quad to track. It is also very similar to what AirDog.com is doing with a wrist band.
Thanks for the link on the crazyfly.
FYI, I'm not saying that certain things in the Nixie are impossible (Many of the individual pieces are possible in some form) I'm just saying that as they present it in their video it is not currently possible, nor do I see it being available for purchase by open market consumers within the next say 3 years. But I do think that you will have "Dronie" based quads in several different form factors, including wearable, pretty soon.

Yeah, but they are looking for funding, so someone is going to pony up. I watched the video. Most of what they show is a Hubsan FPV quad that you can get through places like Banggood it uses a spreadspectrum 5.4 system to broadcast the video and a 2.4 system for control, but it does not have any autonomous capabilities. Hubsan makes some of the best stuff out there and we work very closely with them. The wrist thing is cludgey, and while it conveys the idea (You can see the needed twist I was talking about), it wont get them anywhere near their presented final design. Wifi would be an option, but it would require a wifi hotspot be built into the quad. I know we aren't talking about components that require a bunch of power, but we are talking about small batteries, so every mV counts. Especially for something that is wearable.
Now the Hexo+ is very much like the Airdog. Both seem very viable and are using existing technologies. My only concern about either is what do they do about object avoidance and low battery response. In either situation you can wind up losing the vehicle or injuring someone. Most higher end quadcopters have the ability to Return To Home (RTH) which is great since the pilot is in a stationary position, but put a pilot on the move and things get weird. If you are out surfing and the quad gets a low battery warning due to either a battery failure or having been waiting for 30 minutes for you to catch a wave, where does it go? It could go back to the take-off position, but if you drifted from there then it will need to calculate that distance and make sure it can get back. Salt water and electronics don't play well together. If you take your quad with you for a ride on a skateboard down the boardwalk, how do you make sure it doesn't hit a light post or a tree while it is zipping after you? You could fly at a higher altitude, but the zoom lens on the camera may not be enough. Hexo+ has a video of the founder riding a skateboard while the quad films. Notice that he stops short of going into the wooded area. I wonder why?
There are issues, but at least in both cases I think they are starting from proven technologies and have footprints that are achievable.

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.
