You can find the funniest things in public government documents. There’s always ample evidence your local congress critter is working against the interests of their constituency, nation, and industry controlled by the commission they’re chairperson of. Rarely, though, do you find something surprising, and rarer still does it portend some sort of experiments conducted by Google at a spaceport in New Mexico.
In a publication released last week, Google asked the FCC to treat some information relating to radio experiments as confidential. These experiments involve highly directional and therefore high power transmissions at 2.5 GHz, 5.8GHz, 24GHz, 71-76GHz, and 81-86GHz. These experiments will take place at Spaceport America, a 12,000 foot runway in the middle of New Mexico occasionally used by SpaceX, Virgin Galactic, and now Google.
For the most part, this document only tells the FCC that Google won’t be causing harmful interference in their radio experiments. There few other details, save for what bands and transmitters Google will be using and an experimental radio license call sign (WI9XZE) that doesn’t show up in the FCC database.
Of the few details listed in the documents, one thing does pop out as exceptionally odd: a 70-80 GHz transmitter with an effective radiated power (ERP) 96,411 W. That’s close enough to 100 kilowatts to call it as such. This is the maximum effective radiated power of the highest power FM stations in the US, but radio stations are omnidirectional, whereas Google is using very high gain antennas with a beam width of less than half a degree. The actual power output of this transmitter is a mere half watt.
The best guess for what Google is doing out in the New Mexico desert is Project Skybender, a project to use millimeter waves to bring faster Internet to everyone. There aren’t many details, but there is a lot of speculation ranging from application in low Earth orbit to something with Google Loon.
Quick. What’s the difference in conductivity between silver and copper? Today, that’s easy to find out. You just ask Google (maybe even out loud if you have a phone handy). But it wasn’t that long ago that you needed another option. Before the Internet age, a big part of being “that guy” (or gal) was knowing where to go to find things. You had to be a master of the library’s reference section, know what might be in an encyclopedia or an almanac.
However if you were a hardcore math, science, or engineering geek you probably had, at least, one edition of CRC handbooks. Today, we usually think of CRC as cyclic redundancy check, but back then it was the Chemical Rubber Company.
The Chemical Rubber Company dates back to 1903 when brothers Arthur, Leo, and Emanuel Friedman were selling rubber lab aprons in Cleveland, Ohio (Arthur, apparently, had been in a similar business from 1900). In 1913, the brothers offered a short (116-page) booklet called the Rubber Handbook free with the purchase of a dozen aprons.
The Wall Street Journal reported that [Eric Schmidt] of Google and now Alphabet Inc, promoted the idea of an inexpensive version of the Raspberry Pi to the Raspberry Pi foundation’s [Eben Upton]. Apparently [Upton] accepted this recommendation despite existing plans to make a more expensive, more powerful version of the Pi. The outcome is the Raspberry Pi Zero that sells, in some places, for $5.00 and was given away for free on the cover of the MagPi magazine.
From the WSJ article:
“He [Schmidt] said it was very hard to compete with cheap. He made a very compelling case. It was a life-changing conversation,” Mr. Upton said, adding that he went back to the lab and scrapped all the engineering plans for more expensive versions of future Pi computers. “The idea was to make a more powerful thing at the same price, and then make a cheaper thing with the same power.”
Plans were scrapped. The more powerful Pi 2 was released at the price point of existing Pis, and now we have the Zero.
The Raspberry Pi Foundation is a registered educational charity in the UK. The purpose of this Foundation according to their About Us page is to, ‘advance the education of adults and children, particularly in the field of computers, computer science, and related subjects.’
Why is the Raspberry Pi Foundation so concerned about computer education? From the 1990s onward, fewer and fewer A Level students in the UK applying to study Computer Science had previous experience as hobbyist programmers. An applicant in the 2000s usually might have only done a little web design.
Why then does the Raspberry Pi Zero exist? [Upton] also told Cnet, “We really hope this is going to get those last few people in the door and involved in computer programming.”
Very good, but how well does the Zero support this goal or address their concerns?
In February, Google and Mattel introduced their Hello Barbie Internet-connected toy. This Barbie has an internal microphone, a WiFi connection to Google’s voice recognition services, and a speaker to carry on a “conversation” with the targeted child.
Like the folks at Somerset Recon, we’d say that this is an Internet of Things (IoT) device that’s just begging for a teardown, and we’re totally looking forward to their next installment when they pore through the firmware.
On the hardware front, Barbie looks exactly like what you’d expect on the inside. A Marvell 88MW300 WiFi SoC talks to a 24-bit (!) audio codec chip, and runs code from a 16Mbit flash ROM. There’s some battery management, and what totally looks like a JTAG port. There’s not much else, because all the brains are “in the cloud” as you kids say these days.
From day to day we alternate between the promise of IoT and being anti-IoT curmudgeons, so it should come as no surprise that we’re of two minds about Hello Barbie. First, there’s the creepy-factor of having your child’s every word overheard by a faceless corporation with “evil” in their mission statement (see what we did there?). Next, we’re not sure that it’s OK to record everything your child says to a toy and listen to it later, even if you are the parent. Hackaday’s [Sarah Petkus] summarized this neatly in this article.
But mostly, we’re curious about how well the thing actually works and what it will do with naughty words. And who will take on the task of reviving the Barbie Liberation Organization? Now we totally want to go out and buy one of these things.
There are a surprising number of Raspberry Pis being used in industrial equipment. This means the Arduino is left behind, but no longer. There’s your PLCs that use Arduinos.
A few weeks ago, Google introduced a machine intelligence and computer vision technique that made the world look psychedelic. Now, this library is available. On another note, head mounted displays exist, and a sufficiently creative person could mash these two things together into a very, very cool project.
Welcome to Kickstarter! Kickstarter is an uphill battle. People will doubt you because you don’t have a ‘target audience’ or ‘the rights to this franchise’ or ‘any talent whatsoever’, but that’s what crowdfunding is for!
Several years ago, Apple shipped a few million 17″ iMacs with defective displays. They’re still useful computers, though, especially if you can find a replacement LCD. Apple, in all its wisdom, used a weird connector for this LCD. Here’s the adapter board, and this adapter will allow displays running up to 1920×1200.
[Jan] has earned a reputation of building some very cool synths out of single ARM chips. His previous build was a Drumulator and now he’s shrinkified it. He’s put four drum sounds, pitch CV, and audio out on an 8-pin DIP ARM.
YouTube gives you cadmium! [AvE], recently got 100,000 subscribers on his YouTube channel. Apparently, YouTube sends you a terrible belt buckle when you manage to do that. At least he did it without playing video games and screaming.
Apply some lessons learned in Sci-Fi literature and you’ll come to the same realization I have: Google is going to unknowingly enslave humanity to an artificial intelligence.
I read a lot of science fiction. Generally, the future of technology can be found in great novels if you read between the lines. One of my favorites in this regard is, of course, [Neal Stephenson] who writes cripplingly long books that are totally worth the read due to his brand of fact-backed forward thinking. Look back on my posts here at Hackaday and you’ll see that I frequently apply concepts from his book The Diamond Age to what we see in emerging technology.
Last year my friend [Nils] suggested I give [William Hertling] a try, specifically his Singularity Series which starts with the novel Avogadro Corp. The fictional company is the world leader in free email and data storage. Sound like someone we know? One of the research projects within the company is an email plugin called ELOPe that will parse all past communications and choose topics and phrases that have the highest probability of eliciting a positive response from the recipient. When funding for the project is threatened, the system is turned on. I’d like to avoid spoilers, but let’s just say this puts the system on a path toward enslaving society.
Google is now boasting “Machine Intelligence for You”. It’s a research project based around Gmail which is called Inbox. Inbox has been around for a while but the newly announced feature is an algorithm that reads the email for you and suggests a set of responses. Compared to Avogadro Corp this is only missing two things: the ability to respond automatically, and the directive to protect itself at all costs.
One of the things I liked best about [William Hertling’s] take on an Artificial Intelligence was the low-key nature of the entity. It wasn’t a super-high-level thinker that interacts just like a human would. It was a poor choice by one programmer that led to horrible and far-reaching unintended consequences. No, I don’t really think Google’s Inbox will enslave us. But I appreciate the irony of life imitating art.
Yesterday Google announced preorders for a new device called OnHub. Their marketing, and most of the coverage I’ve seen so far, touts OnHub as a better WiFi router than you are used to including improved signal, ease of setup, and a better system to get your friends onto your AP (using the ultrasonic communication technique we’ve also seen on the Amazon Dash buttons). Why would Google care about this? I don’t think they do, at least not enough to develop and manufacture a $199.99 cylindrical monolith. Nope, this is all about the Internet of Things, as much as it pains me to use the term.
OnHub boasts an array of “smart antennas” connected to its various radios. It has the 2.4 and 5 Gigahertz WiFi bands in all the flavors you would expect. The specs also show an AUX Wireless for 802.11 whose purpose is not entirely clear to me but may be the network congestion sensing built into the system (leave a comment if you think otherwise). Rounding out the communications array is support for ZigBee and Bluetooth 4.0.
I have long looked at Google’s acquisition of Nest and assumed that at some point Nest would become the Router for your Internet of Things, collecting data from your exercise equipment and bathroom scale which would then be sold to your health insurance provider so they may adjust your rates. I know, that’s a juicy piece of Orwellian hyperbole but it gets the point across rather quickly. The OnHub is a much more eloquent attempt at the same thing. Some people were turned off by the Nest because it “watches” you to learn your heating preferences. The same issue has arisen with the Amazon Echo which is “always listening”.
Google has foregone those built-in futuristic features and chosen a device to which almost everyone has already grown accustom: the WiFi router. They promise better WiFi and I’m sure it will deliver. What’s the average age of a home WiFi AP at this point anyway? Any new hardware would be an improvement. Oh, and when you start buying those smart bulbs, fridges, bathroom scales, egg trays, and whatever else it’ll work for them as well.
As far as hacking and home automation, it’s hard to beat the voice-activated commands we’ve seen with Echo lately, like forcing it to control Nest or operate your Roku. Who wants to bet that we’ll see a Google-Now based IoT standalone device quickly following the shipment of OnHub?
