From Qwiic Temp Sensing to Binho USB Hosting

Hello everyone and welcome to another Friday Product Post. We have been hard at work while staggering shifts and maintaining physical distance to make sure new products still arrive. We may not have a huge amount every week for a while, but we are doing our safest and best!

This week we start a new version of our classic TMP102 Digital Temperature Sensor, now with Qwiic! Following our new sensor, we have three new Binho products including a USB host hub, breadboard breakout, and a Qwiic adapter. We finish out the week with the Logitecch C270 webcam - it can be found in the SparkFun DLI Kit for Jetson Nano but it can also be really helpful if you are working from home.

Speaking of which, do you have bored kids at home? Keep them engaged and learning with the help of our Spring Kit Sale - available through April 17th! Designed with beginners in mind, these kits offer a springboard into electronics through circuit building, creating e-textile crafts, measuring the weather, practicing soldering, and exploring the Internet of Things (IoT).

Now onto the new products!

Face Surveillance Is Not the Solution to the COVID-19 Crisis

In the current moment, governments may be tempted to funnel scarce public health resources into the use of face recognition to curtail the spread of COVID-19. Public health crises, especially a global pandemic, may require extraordinary measures in favor of the public good—but invasive face surveillance is not in the public’s interest.

This approach could involve building new infrastructure to conduct more face surveillance and large government contracts with some of the most nefarious surveillance technology vendors in the world. Companies like Clearview AI, which uses over two billion face images scraped from social media to track individuals and identify them with real-time face surveillance, are already in talks with agencies to provide assistance. Even as civil liberties groups call for a national ban on government use of face recognition, U.S. Customs and Border Protection is currently touting face recognition at airport check-ins as supposedly more hygienic than other screening. 

Face recognition may seem convenient and useful, but is actually a deeply flawed technology that exposes people to constant scrutiny by the government.

The massive infrastructure required to run face recognition (such as cameras, software, and open-ended contracts with vendors) cannot be easily dismantled when the public health crisis is over. We cannot allow law enforcement and other government officials to normalize this invasive tactic. We know the truth about this spy tech: face recognition may seem convenient and useful, but is actually a deeply flawed technology that exposes people to constant scrutiny by the government, and has the potential to chill free speech and movement by identifying and tracking people as they visit their doctors, lawyers, houses of worship, or political demonstrations. It also can generate inaccurate reports. 

It is all too likely that any new use of face surveillance to contain covid-19 would long outlive the public health emergency. In a year, systems that were put in place to track infected individuals as they moved through a city could be re-deployed to track people as they walk away from a political demonstration or their immigration attorney’s office. Face recognition software that is able to identify people even when they’re wearing surgical masks, as the company Hanwang has developed, could also be used to identify people who obscure their face at political protests out of fear of retribution from the government. We have to consider the afterlives of these technologies and the way their use can creep into everyday life after the emergency is over.

This is why EFF and concerned citizens continue to call on Congress to ban the government use of face recognition. You can take action here by telling your elected officials that this technology, today and in the future, erodes our civil liberties and undermines our participation in a free society.

You can also take EFF’s new quiz to see what government agencies use or share your photograph for the purpose of conducting face recognition.

.ORG Isn’t Broken, and We Don’t Need Private Equity to ‘Fix’ It

Ethos Capital—the private equity firm poised to purchase the .ORG domain registry for $1.1 billion—and Public Interest Registry (PIR, the entity Ethos wants to buy) have been attempting to respond to the concerns raised by the .ORG community. These after-the-fact changes just make clear that while there is nothing currently wrong with .ORG, there is a lot that could go wrong if this deal moves forward. 

Last week, we wrote about a proposal by Ethos Capital to add certain “Public Interest Commitments” to the contract governing the operation of the .ORG domain registry. Our post explained why that proposal doesn’t solve the problems with the planned sale. Since then, Ethos and PIR have hosted two webinars to discuss how their plan supposedly addresses the concerns that EFF and over 800 other organizations—along with Members of Congress, UN Special Rapporteurs, and state charity regulators [pdf]—have raised. Nothing said on those webinars changed our analysis. Instead, they only further reinforced that Ethos’s plan for a for-profit PIR is one that’s unsound at its very foundation.

While we can—and will—point to specific places where Ethos and PIR’s arguments fall apart, the broader theme to take note of is that this cannot be fixed. All of the proposed changes have holes that don’t get at the underlying problems presented by the deal. On the other hand, the current system is stable and functional, and changing it threatens to introduce instability and dysfunction with no countervailing benefit to the community.

Ethos Touts Its Willingness to Take Risks—But at Whose Expense? 

Ethos and PIR have repeatedly defended the proposed deal by arguing that converting PIR to a privately owned, for-profit enterprise will allow it to offer “new products and services,” but without explaining what those new offerings might be. On Thursday, they finally admitted that they actually don’t know what additional products and services .ORG registrants want or need, citing a lack of market research. Ethos founder and CEO Erik Brooks then made a troubling case for why Ethos’s purchase of PIR would make these hypothetical new offerings possible: Launching new products requires taking financial risks, and non-profit organizations “are not in the business of taking risks”—but Ethos is.

This is not the selling point Brooks seems to think it is.  .ORG’s value to its registrants is being a reliable and recognized domain for hosting their websites and email systems—which it already offers. The .ORG registry should decidedly not be in the business of taking risks with non-profits’ essential infrastructure by adding bells and whistles that no one is asking for. If those risks don’t pan out, it may well be the non-commercial .ORG community that suffers as Ethos makes up for the loss by skimping on technical upkeep, raising prices, engaging in censorship-for-profit—or bankrupting PIR and walking away with the gains.

A Misleading Financial Picture

Ethos and PIR continue to push a narrative that goes like this: PIR currently has to send all of the money it makes to its non-profit parent organization, the Internet Society (ISOC); ISOC then uses those funds for purposes that don’t benefit PIR. As a result, PIR has not had funds to invest in reaching new markets or introducing new offerings. If PIR is freed of that burden, every dollar that PIR would have sent to ISOC will now be available for reinvestment in PIR.

There are a few problems with this narrative. For one, the assertion that PIR is required to send its entire net income to ISOC is at odds with PIR’s articles of incorporation, which establishes charitable purposes other than just financially supporting ISOC. And history shows that PIR can, in fact, invest in itself should it choose to. PIR’s 2018 Form 990, for example, states that PIR spent $1,369,537 on “advertising and promotion” and another $863,042 on “marketing” that tax year. In 2012, PIR took a gamble and applied for six new gTLDs (including .ngo and .ong) to add to its domain portfolio, costing $1.1 million in application fees alone.  In short, we’ve seen no evidence that PIR is an organization in crisis, in need of the kind of radical, fundamental change that Ethos has planned.

At the same time, the financial analysis Ethos presented last Thursday didn’t account for additional expenses that PIR would face post-acquisition. In particular, it didn’t factor in the tax burden that PIR will face if it gives up its tax-exempt status. Nor did it make clear whether PIR will face costs associated with other credit or financing obligations, dividend recapitalizations, or being forced to do business with Ethos’s favored vendors.  A letter we sent to ICANN in partnership with Americans for Financial Reform Education Fund explains our questions and concerns about the financial terms of the proposed transaction, which remain unanswered by Ethos and PIR.

Illusory Safeguards

In both recent webinars, Ethos and PIR have sought to assure community members that they would never take actions that would harm the .ORG community—and that even if they wanted to, their proposed Stewardship Council would stop them. Based on what we know about the Stewardship Council, we’re not convinced. Here’s why:

  • The member selection process guarantees that the Council will always be composed of people friendly to PIR’s board and owners and will not be truly independent. Six out of seven inaugural Council members will be selected by the board, while the seventh inaugural member and all subsequent members will be subject to the board’s veto.
  • The Council’s remit will be narrow—effectively as narrow as PIR’s board and management want it to be. The Council’s charter allows PIR to keep virtually any of the company’s actions or decisions outside of the Council’s scope simply by framing them as operational or financial matters. We’ve already seen PIR do this to justify not consulting its existing Advisory Council about the Ethos deal before agreeing to it. It’s also something we see frequently at ICANN, where any issue relating to registry contracts—including the changes to PIR’s contract that we challenged last year—is framed as an operational, non-policy matter, delegated to staff and exempt from multi-stakeholder processes.
  • It’s a safe bet that the Stewardship Council will be kept in the dark about critical decisions, just as PIR’s current Advisory Council was in the lead-up to the Ethos deal. We asked in both webinars how we could be sure that wouldn’t happen. PIR’s Jon Nevett responded that the Stewardship Council would have a larger role on “certain issues,” but he had no answer to whether and how the Council would have access to information it would need to make informed decisions.
  • Although PIR’s spokespeople repeatedly touted their dedication to free speech, they haven’t offered to change their existing anti-censorship policy one bit. It’s full of loopholes: PIR reserves the right to make websites go dark for “illegal or fraudulent actions.” Depending on which laws are applied and how they’re applied, anything from satire to political commentary to trivial copyright infringement on the website of a business competitor could be justification for taking away a site’s domain name. The power to interpret and apply this policy would rest entirely with PIR and its secretive owners. Nothing in PIR’s “PIC” and “Stewardship Council” announcements would change this—the risk of censorship-for-profit remains.

In Conclusion, Ethos and PIR Want to Change Something That Works Into Something Untested

The for-profit PIR that Ethos envisions would be a fundamentally different organization than today’s PIR, and we have serious concerns about its business model and financial stability.  Nothing we’ve heard from PIR and Ethos has convinced us that PIR should be transformed from something that we all know works to something that’s unproven. To the contrary, the Ethos deal raises concrete dangers of censorship, financial and technical instability, and price-gouging of non-commercial .ORG registrants. And despite making their case for months, proponents of the deal haven’t identified any specific benefits it would impart to .ORG users.

ICANN can, and should, reject this change to the .ORG registry. But that time is running out; ICANN’s current deadline to make a decision is Friday, March 20. You can still speak out: the ICANN Board is holding a public forum next week, Monday March 9 at 10am–11:30am Eastern Daylight Time. Anyone can join by videoconference and address the Board.

Full Arduino code for poultry egg incubator with humidity sensor

A DIY Arduino-based poultry egg incubator with humidity sensor @ reuk.co.uk. Neil writes:

This device makes use of an always on motor which turns the eggs six full turns every 24 hours. Many of our other incubators have motors which have to be set up to run for a certain length of time a certain number of times per day, but the code for these is either specific to a particular motor or far more complicated (but of course more flexible) if the end-user of the incubator is to set these timings.
This device makes use of a DS18b20 digital temperature sensor, a 1602 LCD display module, a DHT11 humidity sensor, and is based around an Arduino Pro Mini, together with some relays, resistors, buttons, terminals, and other components available everywhere – easily salvaged from old and broken electronics even.
