Weird Things Couples Do On Movie Night

One of Those Days 2 - Free Skiing with Candide Flovex

artician says...

I'm not much of a sportsman (I do everything, but poorly).

At one point in my life I had the amazing opportunity to work at a company whose office was literally on the beach in Southern California. Every day at lunch, if the waves were good, everyone would surf.

One time out, one of the rare times I caught a wave and rode it into shore, as I was riding I looked down through the clear water and below my board was a school of at least a dozen fish surfing/following under me, whipping back and forth right under the tip of my board, just enjoying the tide in the same way I was.

That was one of the most beautiful memories I'll have for the rest of my life. Your comment just brought that up, didn't mean to hijack the thread, but wanted to say: Experience everything, everyone. We all deserve at least one magical moment in our lives. That was one of mine. I'm thrilled when I get to see or hear of others.

The pinnacle was at the 2:35 mark in the video when he does a backflip, and there is what looks like an Eagle flying over his head. Awesome.

The Cicret Bracelet-Concept/Scam/Want

AeroMechanical says...

What they're showing certainly is ridiculous, but I'd be pretty happy with a monochrome green projection. That said, in all likelihood some sort of flexible OLED patch or wrist band would probably be practical long before this is. Probably even some sort of fluorescing tattoo.

I do like the possibilities of short throw pico projectors combined with machine vision for user interfaces though. You could take Newtboy's dual projector concept and have something the size of a couple marker pens that unrolls like a scroll, with the screen in the middle.

When it comes down to it, though, what I really want right now is something about the size of a smartphone, with minimized thickness an e-ink display and a limited feature set (phone, text, e-mail, and basic web surfing), the whole design optimized for battery life and performing just those four functions adequately. An easily replaceable battery would be nice too.

You would need to be in a very dark environment for it to look anything like what they show. You can't project anything darker than the screen surface.

Officer Friendly is NOT your friend

lantern53 says...

Enoch, I agree with you 100%.

In my defense, I am not defending bad behavior or bad cops. They make the rest of us (the majority) look bad.

All I'm trying to do is bring some light to the subject. I have inside knowledge of how things are. There is another side to every story, which is one of the first thing a cop learns.

But there are a lot of rabid cop-haters out there (or gathered together in a cave and surfing videosift) who will never accept anything I say or try to see it from another perspective.

Bad cops are the exception, not the rule, which is my focus in these discussions.

When I say that courts have ruled that cops can lie, it doesn't mean cops go around lying to everyone. It means that during an investigation or investigative stop, you can bluff someone to reveal criminal behavior. The courts will certainly let you know that lying in court will result in your termination, the loss of your pension, your whole career.

I agree with you that cops should be held to a higher standard. I don't like fat cops, rude cops, aggressive cops. My favorite co-workers are those with a good sense of humor, self-deprecation and a common-sense perspective.

But whenever I make a comment on here, people just weave these incredible fabrications of corruption and accusation...eventually I think, fuck it, what a waste of time.

Then I take a break and I try it again. What a fool I am!

Nixie: Wearable Camera That Can Fly

My_design says...

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.

ChaosEngine said:

@My_design good info, thanks.

A few things though:
they're not actually looking for crowdfunding at the moment (at least, it's not on their website http://flynixie.com/ )
there are some videos of them launching a proof of concept from the wrist http://youtu.be/_VFsdPAoI1g
but admittedly, you don't see it fly and it's not a slap band as of now.

I have a gopro and it does broadcast, although not in HD in real time. You can connect it over wifi to your phone and see the shot as it is being framed with about a 2 second lag in SD. Both of which are fine as long as the footage is captured in HD. I'll grant you the weight is an issue, but most of that is in the battery and the housing. Nixie wouldn't need a housing, and I'm guessing the wifi/camera power requirements are much less than the motors. Plus it only needs less than a minute of flying/recording time.

Out of interest, since you seem to know about this stuff, have you heard of Hexo+ and if so, what do you think of it?

The Perfect Wave With The Perfect Song

artician says...

That was like a hit of pure ecstasy in video form. Pink Floyd is probably my favorite band of all time. Couple that with such a... perfect... ride...

If you've ever wondered why nearly every surfing video is in slow-motion, it's because even the best rides in the world only last a matter of seconds, but once you're on one, slow-motion is the best available way of describing exactly what it does to you.

Incredibly Fantastic Motorcycle Accident

Kevin Ward Jr. hit and killed by Tony Stewart

Sniper007 says...

Here's a counter theory by another racer:

"I haven't seen how Stewart handled the car preimpact. That said, those vehicles require speed for what little grip they have, as it's largely generated by the roof fin, and they don't really steer so much as surf. If you watch the cornering style it's a full on drift. That makes twitch steering pretty ineffective - you steer from the back which requires heavy throttle.

You don't see Stewart's approach ( at least on the vid I've seen ), and the fishtail post impact I would attribute to the impact itself. His approach does not seem consistent with trying to spray the other driver with dirt ; that would have to be a at a high angle relatively speaking and he seemed to come in straight.

It's possible that Stewart intended to kill, but I really think it's highly unlikely. When you're racing you have a lot to deal with, and whilst under a yellow flag undertaking is typically verboten and in theory you should be slowing down, but in reality you are always looking to get the drop as soon as the yellows disappear. To that end you're scanning the track looking for disabled vehicles.

You're not scanning for drivers standing in the middle of the track - the assumption would be that the driver stays safely secured in the car, or they hop the barrier. If that can't happen for some reason, it's the job of race control to red flag the race.

My personal theory, based on incomplete footage - I'd like to see in car footage from Stewart ideally - is that Stewart just didn't see him in time to make any effective attempt to miss. It's a night race, and Stewart would have been concentrating on the disabled vehicle to his right. There's not much about Ward's outfit that would attract attention - from Stewart's perspective, black helmet, black racesuit, against a dark dirt background. These vehicles don't use headlights, so there's nothing to offset the glare of the spotlights.

In a perfect world Stewart would have seen and avoided, but ultimately Ward put himself in a fucking stupid position and paid the price. I'm not surprised to see lack of remorse on Stewart's part ; Ward shouldn't have been there, plain and simple.

Anyhow, that's my thinking on this - I don't know or follow anyone in that type of series, so I'm claiming to be bias free here. Racers know that motorsport is dangerous, so you do what you can to mitigate risk, not increase it by orders of magnitude.

Edit : Looking at it a few more times, it's also possible that Stewart was trying to rotate the car around Ward - throttling up and steering right would have pushed the back away from Ward, which might have made the outcome different. I still say it's a Darwin."
