FAA's regs are doomed
Here’s the Reason The FAA’s Drone Registration System Doesn’t Make Sense
A few years ago, Congress passed the Modernization and Reform Act of 2012, an immense 300-page tome that set directives to the FAA including how airports should be improved, what medical certificates apply to what type of pilot, and special rules for model aircraft.
The Administrator of the Federal Aviation Administration may not promulgate any rule or regulation regarding a model aircraft, or an aircraft being developed as a model aircraft
In the Modernization and Reform Act of 2012, ‘model aircraft’ are defined as, ‘an unmanned aircraft capable of sustained flight in the atmosphere, flown within visual line of sight, and flown for hobby or recreational purposes.’ If these qualifications are met, the FAA may not make a rule regarding these aircraft, so long as they are not flown within 5 miles of an airport.
Geez, read about it here....

Haptic compass?
It isn't what you'd call god's gift to style; but there's a neat little idea floating around of the 'haptic compass' that provides the user with a tactile cue about where north is, with the idea that this subtle, but persistent, stimulus will be integrated into their overall navigational capability.
For your use case, you probably wouldn't want a system that points 'true north' all the time; but if you have an itinerary, you only need a real time clock and the user's current location to provide a haptic nudge in the correct direction. Are GPS or AGPS fixes within this facility OK, or is this system going to need to navigate the hard way? -

Windows IoT Core is meant for embedded systemsI gather from the Hackaday review of Windows IoT Core on the RPi that is is very much for embedded systems. To quote from the review
This is not a device for makers, this is a device for point of sale terminals and ATMs. Windows XP – the operating system that is still deployed on a frighting number of ATMs – is going away soon, and this is Microsoft’s attempt to save their share of that market.

It was a BlackHat / DEFCON publicity stunt
Hackaday is pretty much spot on: http://hackaday.com/2015/07/14...
There's always posturing for PR before BlackHat and DEFCON. This was to get the researcher's name on people's radar.
Many a competent unix sysadmin could come up with something similar.
What's hilarious is that despite how easy it would be to make something like this, the "researcher" just bought a yagi antenna and posed for a picture. They didn't even bother to point the yagi antenna towards the ground, for that matter.

I have lots of junk and not much money, so...
Old HP GPIB-based XY plotter with laser diode in place of pen, does a nice job of cutting gaskets for steam engines.
Broken 8 track player in ginormous am/fm/turntable cabinet, replaced with beaglebone, so when I hit the next track button it plays a 'clunk' sound and then fires up a random streaming internet radio station. (That one made hackaday.)
A nearby company went out of business and sold all their stuff and I scored an electronic balance with an RS232 output. Some arduino code later, and I now have a fuel injector flow tester: force known-pressure fuel in for a known amount of time and measure how much actually comes out, tare, repeat. It's neat to be able to characterize just how narrow a PWM signal the injector can register and react to.
My current work project is even a hack: I'm repurposing an abandoned semiconductor automated test system into an evaluation board characterization system. The test guys don't want it because it's too slow and limited, but I'm all "whoah, 192 arbitrary waveform generators? Let me at it." -

Recently? Tempest ?
Here's a post from 10 years ago about a program that can turn your display into a radio transmitter. I think that the provided code plays a midi version of Beethoven's Fur Elise, but there are variations that play any mp3.
Just to be clear: this works by calculating the pixelclock then using high/low (white/black) swings to generate Electro-Magnetic signals at the corresponding frequencies. I remember running this on an old 300MHz PII Thinkpad. It transmitted through the VGA port and could easily be picked up on portable radio 5 feet away without any antenna
This was a bit of a reverse proof of concept for the NSA's Tempest project. Tempest listened to EM noise and tried to reconstruct what was on the screen (or in the chip / whatever). This demo crafted a display resolution/image such that tones were the EM byproduct

Re:Well...
Time to make a Faraday Cage wallet.
Time to permanently disable contactless payment on all your cards.
Apparently the banks and credit card companies in some countries will send you a new card without the RFID on request. But here in Canada at least one company simply refuses to do this. My bank DID disable contactless payment on my new debit card in their records, but of course the RFID is still physically intact so there's no guarantee that it won't suddenly start working as a result of some administrative fuckup. I'm going to call about my new credit card, but I'm pretty sure they'll tell my politely to piss off. At that time I plan to get out my drill, put a hole in the appropriate place, and test. If it disables Tap and Pay, then all of my cards will get the same treatment.

Re:a billion operat per second enough for cat wate
If you want to control a few motors and lights with network connectivity, get some ESP8266 modules - those are WiFi modules with a user-programmable 80MHz 32-bit CPU that you can buy for $5. Throw in a Cortex-M0 as a slave device to control your I/O (which can be as cheap as $1 in single quantities - yes, you can get a 32-bit CPU for $1 these days). That is what 2015 state-of-the-art silicon gets you to fit the task. A Raspberry Pi with a WiFi dongle is an order of magnitude more expensive and overpowered (and yet underpowered relative to what it claims to be, which is a Linux platform).

They tried like only RadioShack can
They just tried too late, and made such a tepid entry, it only served to get people exposed locally, and ultimately hooked up with SparkFun and Adafruit (or eBay for knock-offs which RS could damn well produce in Fort Worth, TX.)
First, RadioShack acknowledged there was a need, so they teamed up with Make and began carrying Arduinos.
Then they made a very public appeal to the community for feedback on how to be awesome again. http://hackaday.com/2011/05/27...
Next, the stores received a Bright White remodel that did nothing but highlight how few people there were in the store, and there was that Super Bowl commercial that may serve as Tandy/Radio Shack Corp's epitaph.
You may notice the rather complete shelf of branded electronics tools and racks of organized component drawers, largely missing from most of the stores you've been in lately.
They could be *owning* the SDR and Quadcopter market with DIY and R2R set-ups, workshops. The 3-D printing and DIY screen repair stations are cool but unused and expensive.
Bottom line; RadioShack's used to *BUZZ* with activity. There were computers humming, disk drives loading, an ungodly cacophony of "Made in Taiwan" beeps and squawks, CB's that needed squelch, and customers enjoying and producing that buzz.
It's gone, and no number of Cell Phones will bring it back.
Domestic Hi-Fi for the blue collar audiophile could, so could an in-house engineering department that hires grads and rewards them with equity. Take the damned thing private for a while, narrow the focus.
Hell, I'd even advocate for a merger with MicroCenter or buyout from Adafruit or SparkFun. (10MM could have bought more than greenfield construction)

http://hackaday.com/2014/11/11... might also have some nuggets. a lead acid battery is going to be heavily de-rated at the energy rates required. lead-acid will likely not have the same charging efficiencies.
holding the batteries around 70% is no big loss for this use case, given that the alternative is shortening the battery life.

Re:Will it have the same garbage CPU?

http://makezine.com/category/e...
Seems to me like thousands of people are finding interesting things to do. Of course it is not fast enough for everything, but nor is my i7 laptop, or the 48core server box I use at work.Small. Ok, that's relative. Its been fine for my uses, smaller than the beagleboard and mini-itx boards I used before. The A+ is even smaller. Interested to know what project you are doing where the pi is too big and too slow, what do you use instead?
Cheap. sorry if $25/$35 is too expensive. Its a quarter the price of the beaglebaord that I used before. Maybe you can find something cheaper for your specific task.
Widely available. In the UK there are several high street shops with it in stock, and lots of online retailers.
Documentation. Personally GPU docs don't interest me (though they are now released, so its the most open arm SoC). When I have wanted to use the pi in a project I have found lots of documentation and tutorials to help me.
Well supported. 2.5 years after release they are still doing regular software updates, including big things like wayland support. Compared to lots of hardware that is released with some old distro image that never gets any updates.
So yes the raspberrypi is awesome. It lets lots of people do interesting things at a good price. Sure for certain things an atmega, beaglebaord, banana pi, gumstix, galileo, an old pc or something else might be better.

Re:A great family of products
For my own use, I was thinking of turning mine into an airplay-compatible receiver (I found that there is software for for that) and built it together with (wifi dongle and a little amp) into a very old radio cabinet. Nice to put in the kitchen.
If your radio is still in semi-working condition, it might be possible to inject the audio signal from the Pi into the radio's existing amplifier. I almost certainly broke all kinds of audio design rules, but in my instance it sounds brilliant. I (briefly) got it working as an Airplay receiver, but for nearly two years it's been doing sterling stuff as a time-delayed BBC Radio 4 device.
(I would definitely recommend against blindly doing this with stuff that's directly mains-powered - I know that a lot of old radios, especially in the USA, did scary things with mains voltages. For a battery-powered transistor radio? Certainly worth a try.)

Re:The obvious solution

-
The obvious solution
The obvious solution is to return to traditional methods: establish an independent income, then take up scientific research as a hobby.
Historically, our most notable scientists were working at day jobs or otherwise independently wealthy, and did amazing research on their own as a hobby. Some devoted entire wings of their house towards scientific research, amassing a collection of equipment (or specimens) over decades.
Henry Cavendish, of the Cavendish experiment, is one such example. The experiment was so delicate that air currents would affect the measurements, so Cavendish set up the experiment in a shed on his property and measured the results from a distance, using a telescope.
There used to be a term "Gentleman Scientist" for this, but it might more accurately be called "self-funded research".
Consider Paul Stamets as a modern example. With only an honorary doctorate, he is co-author on many papers and has proposed several medications, including treatments for cancer.
I could also nominate Robert Murray Smith to the position. His YouTube Videos are as good as many published Chemistry papers.
The benefits are obvious: You get to work on whatever you think is interesting (or fruitful), you can set your own pace, and you can draw your own line between supporting your dreams and your lifestyle: If you have a family emergency, you can pause your research and spend more money on personal welfare. It also forces you to come up with more efficient (read: less expensive) ways to work.

Electrical Network Frequency analysis
The hum that helps to fight crime (ENF) Electrical Network Frequency analysis
"For the last seven years, at the Metropolitan Police forensic lab in south London, audio specialists have been continuously recording the sound of mains electricity.
It is an all pervasive hum that we normally cannot hear. But boost it a little, and a metallic and not very pleasant buzz fills the air.
..."The power is sent out over the national grid to factories, shops and of course our homes. Normally this frequency, known as the mains frequency, is about 50Hz," explains Dr Alan Cooper, a senior digital forensic practitioner at the Met Police.
Any digital recording made anywhere near an electrical power source, be it plug socket, light or pylon, will pick up this noise and it will be embedded throughout the audio.
This buzz is an annoyance for sound engineers trying to make the highest quality recordings. But for forensic experts, it has turned out to be an invaluable tool in the fight against crime.
While the frequency of the electricity supplied by the national grid is about 50Hz, if you look at it over time, you can see minute fluctuations.
...Comparing the unique pattern of the frequencies on an audio recording with a database that has been logging these changes for 24 hours a day, 365 days a year provides a digital watermark: a date and time stamp on the recording.
Philip Harrison, from JP French Associates, another forensic audio laboratory that has been logging the hum for several years, says: "Even if [the hum] is picked up at a very low level that you cannot hear, we can extract this information."
It is a technique known as Electric Network Frequency (ENF) analysis, and it is helping forensic scientists to separate genuine, unedited recordings from those that have been tampered with."

Re:Wish I could say I was surprised
I think what the poster you quoted wanted to say is that often to make major contributions you have to do something that has never been done before, and not just follow up on previous research. Pushing on current trends is not difficult, at all, and is basically guaranteed to get you a publication in a decent journal. A lab head can do several dozens of these papers a year if he has a few handfuls of people in his group and decides to have his focus on this. Now doing this more than guarantees a comfortable living as an academic. Quite often this research can even be wrong: It's middling at best, and nobody really cares, so nobody will notice (and yes, the STAP scandal with Obokata et al. is really a special case and not what usually happens; their claims were "too" interesting to the general public and in any case outright fraudulent). Many fields are saturated by this type of managers (rather than scientists), and they have been rewarded for their noninnovative research for so long I doubt they would even recognize a basic flaw in a paper when they saw one.
This means that peer review has become useless (when your peers are managers rather than scientists) and in fact every month I spot papers from my field in some of the top journals that have zero scientific contribution: their methods are only borderline correct, and the conclusions known for decades. But they have nice pictures and peer reviewers are probably their manager-friends or manager-somebodyelses who did not have a clue what was done and well-known 50 years ago (and indeed, why care, if by ignoring old research you can accidentally redo them and get more papers!). Try publishing a paper showing that their experiment must be wrong as it violates the second law of thermodynamics and you will be shot down and now they know your name. Good luck with grants and peer reviews.
I got a bit derailed above, but no, I am not bitter nor is the above a completely accurate presentation of my personal experience. This said, it is obvious that many scientists are afraid of speaking their mind and criticizing others even when others are wrong, and that this is corrupting the entire system where one is supposed to be able to trust one's peers.
Back to the topic: Coming up with a totally new idea, trying it, and failing at it will never get written up. You say that this is the right thing to do, if you don't publish, you ought to perish. Now is failed research "wrong"? Should you have known beforehand that your idea is stupid and not even test it? Not being able to publish this failed idea and only regarding publications as a measure of your success would certainly imply this.
Hack a Day publishes fails of the week. They are not meant as articles where we laugh at someone's stupidity or bad luck, but are informative writeups about new ideas where something in the implementation went wrong, or serve as examples of how even experienced people can fail to consider some basic (or advanced) principles. Related to this, perhaps my favourite TED talk is that by Eddie Obeng. He talks about business, not research. And I remind you that the only reason university research exists is that otherwise fundamental or high risk projects would not get funded as you might not have a direct way to make money off of them, or you might lose a lot, which makes them unattractive for business. Surely Obeng will then tell you that as a business manager, do the safe projects, punish those whose ideas don't work. Well this is what he says: "You're doing something new that nobody's done before, you get it completely wrong. How should you be treated? Well, free pizzas! You should be treated better than the people who succeed. It's called smart failure. Why? Because you can't put it on your CV." Companies can treat their employees with pizzas when they fail at something new, but academia is not a structured system where you could get different kinds of rewards: it is only about publish or perish. This is why it is a horrible system.

Re:Slashdot Effect
Hackaday had a similar discussion just over a month ago. The consensus there seems to be likewise that it is probably a scam. (Or *extremely* optimistic kid who has seen a few of the technologies involved work on paper. But more likely a scam.)

Re:Well then
Oh, but you can. Well it's not exactly the same thing. Have you heard of a femtocell doodad? When I first heard of stingray, I thought back to an interview from a guy at blackhat or defcon, I can't remember which. Anyway, here's a few links. I remember hearing them say that the traffic from the devices communicated w/o encryption to the servers. Supposedly that was fixed, but may very well still have more vulnerabilities like this one.

so 1) they already do sell things with retarded capability to consumers
2) the argument "we don't want the criminal element to know we have this kind of capability because they'll know how we find them" is invalid.

Here are couple of $250-300 3D printers
Hey all, theres been a bunch of low cost 3D printers poping up at Hack-A-Day lately:
$300 Pick and Place / 3D printer - http://hackaday.io/project/963...
Prototype of a Servo based Printer (much cheap elecytronic) - http://hackaday.com/2014/05/26... -
Re:Total misrepresentation of Evolution
If he were to wire billions of circuits by randomly wiring together components, then he might end up with a few that were useful.
There are people who did exactly that with simulators and FPGAs. Some of these circuits have peculiar properties like being very sensitive to the substrate they're working on, and I got the overall impression that they're sort of messy and "un-designed-like", just like living organisms, as opposed to engineered machines.

What about Wi-Fi microSD cards?
These little guys appear to be running Linux, and some are even hackable (I'm not affiliated with any of these companies/blogs): http://www.monoprice.com/Produ...
