ACLU says demanding US citizens unlock phones at the border is unconstitutional via The Verge

The American Civil Liberties Union has filed an administrative complaint with the federal government after a US citizen was detained at the border and forced to unlock his iPhone SE. Aaron Gach, an artist and activist who was holding an exhibition in Belgium, was subjected to interrogation by US Customs and Border Protection upon his reentry into the country at San Francisco International Airport in February. Gach was forced to unlock his phone, and in doing so the ACLU says CBP agents violated Gach’s constitutional rights, specifically his Fourth Amendment right protecting him from unlawful search and seizure.

Arduino Trinket - Ocean-roaming data buoy | Hackaday via hackaday.com

An amazing free-roaming, ocean buy with tracking information. Is this something your STEAM group could put together — together? — Douglas Put a message in a bottle and toss it in the ocean, and if you’re very lucky, years later you might get a response. Drop a floating Arduino-fied buoy into the ocean and if you’ve engineered it well, it may send data back to you for even longer. At least that’s what [Wayne] has learned since his MDBuoyProject went live with the launching of a DIY drift buoy last year. The BOM for the buoy reads like a page from the Adafruit website: Arduino Trinket, an RTC, GPS module, Iridium satellite modem, sensors, and a solar panel. Everything lives in a clear plastic dry box along with a can of desiccant and a LiPo battery.

Google opens up Classroom so anyone can now become a teacher via The Next Web

I often find myself assisting my college professor wife with her online classrooms using Blackboard, Moodle and others. This also has me often thinking about putting together my own online courses. Google has made this much easier by providing everyone access to their new Classroom service.  Poking around in it the other day, it seems very similar to other online classroom products I have used and could provide you with an easy method of hosting your own educational projects -- Douglas Google is opening up its Classroom educational service to allow anyone to create and teach a class on its platform.  The web-based tool works across devices and Google says it can be used to help manage classes for adult education, hobbies, and after school programs.  Classroom should come in handy for people who want to do more than just post tutorials on their blogs and YouTube channels; they can add resources, post tasks and assignments and interact with students as they...

Live Out Your Astronaut Dreams With Lego's Meter-Tall NASA Apollo Saturn V Rocket via Gizmodo

Lego seems to be the “gateway drug” for so many makers and I couldn’t help highlighting this amazing kit. The sheer size and number of bricks included in this model are mind boggling. Even better, you can get your own version to build. The Saturn V was the THE rocket of my child hood and I watched many of them launch on TV with all the Apollo missions. It brings back some amazing memories— Douglas To this day, the Saturn V remains the largest and most powerful rocket NASA has ever blasted into space, which is perfectly reflected in Lego’s new Apollo Saturn V model. That model stands a full meter (over 39 inches) in height, with the Apollo lunar lander, lunar orbiter, and astronauts, hidden away inside. The set started life as a Lego Ideas submission by builder saabfun, who quickly achieved the 10,000 votes from fans required for Lego to consider it for production. It was eventually approved, and while the final version of the Apollo Saturn V looks quite a bit different than saabfu...

Onion Pi makes your web traffic anonymous via Open Electronics

Hmmm, might be an easy (and relatively cheap) way to play around with Tor and learn a bit more about this anonymizing service. -- Douglas Adafruit’s Onion Pi is a Tor proxy that makes your web traffic anonymous, allowing you to use the internet free of snoopers and any kind of surveillance. Follow Adafruit’s tutorial on setting up Onion Pi and you’re on your way to a peaceful anonymous browsing experience. Tor is an onion routing service – every internet packet goes through 3 layers of relays before going to your destination. This makes it much harder for the server you are accessing (or anyone snooping on your Internet use) to figure out who you are and where you are coming from.

Emulate the Golden Age of the Macintosh Thanks to the Internet Archive via Kotaku

I remember these days. In college I was able to use one of the first 128K Macs although I was mainly an Apple II user at the time. In 1989 I purchased my first Mac Plus and I have been mainly a Mac user since then. This brings back some memories both pleasant and not of those times. (LAUGH) — Douglas Along with its duties of maintaining copies of important news, literature, scientific information, and old MySpace pages, the Internet Archive also loves to create emulations for you to fiddle with inside your browser. Today, the lovable non-profit organization has made it easy for you to relive the glory years of the early Macintosh like it’s 1985 all over again. There’s something about the black and white interface of the original Macintosh computers that’s timeless. Sure, it might remind people of the Reagan-era but it is such a pleasing design that one could easily imagine it being a minimalist OS mod for people who want to simplify their user experience.

How an LED Works via Today I Found Out

Learning is an amazing thing. I try to learn something new everyday on the “Today I Found Out” web site and YouTube Channel are a great way to do that. While I understood some of the basics of how LEDs work, this article provides an in-depth analysis of all the complicated things that go on inside and LED even though it seems simple on the surface. Dive into the inner workings of the LED and more on this excellent web site. — Douglas Today I found out how an LED works.  An LED or “Light Emitting Diode” is basically as the name describes; it is a special type of diode that is specifically optimized to give off light, usually in the visual or infrared spectrum, as electricity is passed through it. A diode is a special type of semiconductor that has many uses.  One of the principle uses though is to control the direction of the flow of electricity.  The most common type of diode does this by using something called “p-n junctions”.  This is just a fancy way of saying “magic”. 😉 Read...
