Many parents and students across the United States will be facing the prospect of hybrid learning. What is it? What challenges does it entail? How can families best prepare for this unprecedented back to school season?
Here are some first steps when thinking about hybrid learning from Joaniko Kohchi, LCSW, IMH-E, director of Adelphi University’s Institute for Parenting in New York, and other experts, via Parents.com:
As summer draws to a close, school districts nationwide are scrambling to make plans for the 2020-2021 school year. Some have tentatively resumed in-person classes, knowing that COVID-19 still remains a threat. Others chose either virtual learning or “hybrid learning”—a mix of remote education and traditional classroom experiences catered to individual students. In each scenario, your child can expect school to look different this year.
“Thinking ahead, the very first thing is for parents (and kids) to pause and realize that nothing is ever going to be like this past spring semester,” notes Joaniko Kohchi…. “We were collectively in shock and had to respond the best we could. We now know a lot more about how to teach, what our children need in order to learn, and what we parents need in order to work. We can all build on that experience and plan accordingly.”

Researchers from Cornell University unveiled a robot as small as a a single cell. Here’s more form Engadget:
The robots themselves are only 5 microns thick, 40 microns wide and between 40 and 70 microns long, depending on the design. The brain and body consist of a silicon photovoltaic circuit while the legs are made from a quartet of electrochemical actuators.
“In the context of the robot’s brains, there’s a sense in which we’re just taking existing semiconductor technology and making it small and releasable,” [Cornell professor Paul McEuen] told Cornell News. “But the legs did not exist before. There were no small, electrically activatable actuators that you could use. So we had to invent those and then combine them with the electronics.”
Smithsonian shares the new study published in Current Biology from their own Nathan Cooper, a behavioral ecologist of the Smithsonian Migratory Bird Center.
What Cooper and co-author Peter Marra found, though, wasn’t as simple as one big round trip. Once the birds arrived in Michigan, many of them started making long trips to different spots within the breeding area. The trips ranged anywhere from three to 48 miles, and most of the traveling birds were those that weren’t breeding that season. What could they be up to?
Ornithologists have a word for the birds that bop around a bit during breeding season. These birds are called “floaters,” and experts knew that these birds moved around the space of particular breeding sites. But the behavior of these birds isn’t easy to track.

Diminished chords have a distinct tone that’s eerie, dark, and dissonant. Here’s what a diminished chord is: a triad built from the root note, minor third, and a diminished fifth. But what does that mean? Here’s an exploration of diminished chords from Icon Collective:
For example, a C major triad has the notes C (the root), E (the third), and G (the fifth). Therefore, a diminished C triad has the notes C, Eb, and Gb.
However, the flattened fifth makes diminished chords sound unstable and creates a desire for tonal resolution. They leave the listener hanging, which makes the resolve back to consonant chords more impactful. This sense of tension makes them interesting chords to use in your progressions.
What if you never have to worry about power outages again?
via The Verge
Three thousand Californian apartments will be linked up to solar panels and batteries — meaning they might never experience a power outage again, no matter what California’s utility companies do. The project, planned by German energy storage company Sonnen, will be spread across seven apartment complexes — the largest of its kind.
The connected set of solar panels and batteries form what’s called a “virtual power plant.” Besides making sure the whole community can run on backup solar power during blackouts, these VPPs also reduce strain on the grid — because VPPs store their energy on-site. What’s more, they can be tapped to provide energy during demand peaks.
Learn about the newly unveiled statue and a timeline of statues in NYC from Gothamist:
This is the first statue in Central Park to depict real women, a celebratory occasion, but one that was briefly controversial when the group behind it — the nonprofit Monumental Women’s Statue Fund — originally chose to feature only white women, casting aside the importance of Black women’s voices in the fight for the right to vote.
The blue planet’s blue parts are a great mystery because the origin of water on earth has never been concretely determined. A new study provides evidence that the water has been here all along and was a constituent in the building blocks.
Via NPR:
A new study in the journal Science suggests that the Earth likely got a lot of its precious water from the original materials that built the planet, instead of having water arrive later from afar.
The researchers who did this study went looking for signs of water in a rare kind of meteorite. Only about 2% of the meteorites found on Earth are so-called enstatite chondrite meteorites. Their chemical makeup suggests they’re close to the kind of primordial stuff that glommed together and produced our planet 4.5 billion years ago.
Eric Deggans and Life Kit put together these 4 suggestions for folks learning how to be anti-racist:

Max Braun discusses putting a Raspberry Pi inside an Apple iSight:
Allow me to take you back to the year 2003. The iPod is still a thing. It’s playing “Hey Ya!” by OutKast. You can get an iBook in white plastic. Life is good. Apple is also selling a webcam. They call it the iSight, and it’s a beautiful piece of design and engineering. It even comes with a travel case and multiple different stands. You can find pictures of it in all its glory on Andrew Kim’s blog.
Apple hasn’t sold another iSight since 2006 and the downside of 17-year-old consumer electronics is that they are 17 years old. 640×480 is not a camera resolution anymore, it’s an app icon. Remember Firewire? I don’t.
The Raspberry Pi Zero fits the iSight’s dimensions almost perfectly and, incredibly, it costs only $5.
See Max’s article on Medium and on Twitter on how this was done.

RadioGlobe is an interactive tool to access over 2000 stations (and counting), from all over the world.
Part of the magic is the the tension between familiarity and the unfamiliarity: It’s both shocking how many radio stations play Western pop music, but then with a turn of the jog wheel, you find an alternatives (in the same location) – and you navigate from Boosh FM‘s Drum & Bass, to listening to a native dialect of New Zealand. It’s frankly, mind-blowing, even though the technology has been around for years.
The project is Open Source. The GitHub repository is open to anyone who would like to evolve the code to make the RadioGlobe even better.

This industrial looking robot was featured in MagPi. Now more than ever its important to remember to #MakeRobotFriends. Via MagPi:
The single-board computer features prominently in Joseph’s Project Zed robot, created as a means of encouraging citizens to take sensible health precautions. “A friend said ‘build a robot that can help in fighting Ebola in West Africa’. That was in 2016 and we didn’t take it seriously because no cases were in Uganda, but when 2020 came I got to work. With a robot, he says, “you can carry out random tests and collect information from someone without risking important medical workers.”
Raspberry Pi enabled Joseph to add personality and voice-based interaction to the robots he’s built, as well as delivering preset messages such as “don’t forget to wear a face mask”.

Al Williams on Medium discusses the steps to try out running Linux with a 64 bit kernel and the potential speed improvements.
Will it make a difference? That depends on what you are doing. Working with higher memory loads or USB 3 is probably going to be a bit faster. For some things, it won’t make much of a difference. Especially since all the applications are still running in 32-bit mode.
Just as a quick test, I tried to create a large file on the SD Card:
dd if=/dev/zero of=~/test.dat bs=4096 count=512KOn average, the operation took about 104 seconds with the 32-bit kernel. With the 64-bit kernel it only took 76 seconds. That’s worthwhile, although depending on the task, you could see more or less improvement.
He cautions that not all software will run in a 64-bit environment and the very sensible advice to use a backup of the operating system in case of issues.

Stressberry is software which stress tests and provides temperature plots for the Raspberry Pi.
There are a million ways to cool down your Raspberry Pi: Small heat sinks, specific cases, and some extreme DIY solutions. stressberry is a package for testing the core temperature under different loads, and it produces nice plots which can easily be compared.
The run lets the CPU idle for a bit, then stresses it with maximum load for 5 minutes, and lets it cool down afterwards. The entire process takes 10 minutes. The resulting data is displayed to a screen or, if specified, written to a PNG file.
See the GitHub repo for more information, it’s under a GPL 3.0 license.
NODE has come up with an excellent method of building an open source mini-server based on the new Raspberry Pi 4.
…One of the main goals here is to package the Raspberry Pi in a form factor that makes it a little bit more useful as a regular mini server or computer. That means putting it all in a neat box, with all the ports on one side.
I decided to simplify the concept further, so everything is encased in a 92x92mm enclosure, with a thickness not much larger than the Pi itself at 26mm or about 1 inch.
The design requires no modifications to the Pi itself. There is also an option to add an mSATA SSD, which connects to one of the USB3 ports.

Here’s an excellent project for to make ultrasonic distance measurements. From Radu Mihai Rotariu via hackster.io:
A basic ultrasonic sensor consists of one or more ultrasonic transmitters (basically speakers), a receiver, and a control circuit. The transmitters emit a high frequency ultrasonic sound, which bounce off any nearby solid objects. Some of that ultrasonic noise is reflected and detected by the receiver on the sensor. That return signal is then processed by the control circuit to calculate the time difference between the signal being transmitted and received. This time can subsequently be used, along with some clever math, to calculate the distance between the sensor and the reflecting object.
The HC-SR04 Ultrasonic sensor we’ll be using in this tutorial for the Raspberry Pi has four pins: ground (GND), Echo Pulse Output (ECHO), Trigger Pulse Input (TRIG), and 5V Supply (Vcc). We power the module using Vcc, ground it using GND, and use our Raspberry Pi to send an input signal to TRIG, which triggers the sensor to send an ultrasonic pulse. The pulse waves bounce off any nearby objects and some are reflected back to the sensor. The sensor detects these return waves and measures the time between the trigger and returned pulse, and then sends a 5V signal on the ECHO pin.
The PM2.5 Air Quality Sensor guide originally included both Arduino and CircuitPython examples. However, the examples were complicated and ran standalone. Enter the Adafruit PM25AQI and Adafruit CircuitPython PM25 libraries!
We created libraries for both Arduino and CircuitPython to make reading data from this sensor much simpler. Each library comes with an example. We updated the guide to include how to install the new libraries, and where to find the new examples! If you picked up one of these sensors but wanted a simpler way to read the data, this guide has you covered.

Here’s a project that uses image recognition, and the glory of disco to test out some of what AI can do. If a person walks into the room, “Stayin’ Alive” begins to play. But if a dog walks into the room, “Who Let The Dogs Out” plays. Here’s more on the project from mark via hackster.io:
The camera captures the scene and the data is sent to the inference engine (in this case Openvino). The data is then transmitted to the node-red instance running on the Vizi-AI (greater detail of this process shown below). This processes the labels generated by the inference engine and if a person is detected it send a MQTT message to the broker (topic, control payload “Disco”).
The Relay python application running on the raspberry pi is subscribed to the control topic. When it receives a message on the control topic, it examines the payload, if the payload consists of “Disco”, it starts the Disco lights and plays “staying alive”. after 30s of music and lights, the light switch off and the music stops, until either person or dog is detected.

A very mini Mac shared by Tom Nardi on Hackaday. Project and Video by Michael Pick on YouTube
We know that some in the audience will take issue with calling a Raspberry Pi in a 3D-printed case the “World’s Smallest iMac”, but you’ve got to admit, [Michael Pick] has certainly done a good job recreating the sleek look of the real hardware. While there might not be any Cupertino wizardry under all that PLA, it does have a properly themed user interface and the general aversion to external ports and wires that you’d expect to see on an Apple desktop machine.

Yes, this is yet another drawing machine based on the coreXY principle, which is well known from the AxiDraw maschine. But instead of driving the size upwards like other designs here on the web, I have decided to keep it very compact, limiting the drawing area to the size of a postcard (DIN A6). I have then used the reduced mechanical requirements that come with the smaller size, to make it very simple and very cheap to reproduce. At that size, very good accuracy can be achieved even without metal linear ball bearings.

A nicely designed bracket for iPhone Pro Max Structure Sensor from artificialdata on Thingiverse:
This bracket is for an iPhone 11 Pro Max to use an Occipital Structure Sensor. This was designed specifically to fit the 3-camera bezel on the rear of the iPhone. The design keeps enough contact with the phone to stay on but loose enough to be removed quickly.
For a tighter fit, place a low tack tape inside the bracket to increase friction. iPhones are slippery!
Additional design consideration was to include a flat top on the bracket so it can be turned upside-down and used as a stand when not in use.
