21st Century Learning and Teaching

One of the first lessons many people learn when starting off learning practical, hands-on electronics is the need for pull-up resistors. Whether to prevent floating I/O pins on a microcontroller or interfacing two circuits via an open-drain design; pull-up resistors are an often necessary but rarely appreciated component. So why do we use pull-up resistors, can’t we just connect a wire to the Vcc supply of our device? What size resistor should you use?

ABOUT THIS PROJECT

This is a robotic owl that looks around for cool people, and can tell whether you're happy or upset. If you're excited enough, he will eventually let you take a sticker (or other small giveaway). He's named Archimedes, after Merlin's familiar in TheOnceandFutureKing. Of course, it's also reminiscent of the cyborg owl in Blade Runner.

First up, if you don't know the Google AIY Vision Kit, check out the details here! This is the basis for the robot's smarts. The code for this project is coming soon.

It started when we were invited to contribute something to the Google booth at Bay Area Maker Faire. I took a really, really long time to figure out what to build—what it would look like, how it would animate, how it would dispense the stickers... in the end, I went with this cute and fairly challenging design.

This robot is versatile enough that I can bring it along to different events, such as the CODAME Artobots Festival and the Arm/Hackster Asia Tour (since the Raspberry Pi runs on an Arm chip, the Broadcom BCM2835). In other words, I can justify spending this much time on one project because I can re-use and iterate upon it. I'm also excited to have a sidekick in the office :)

FriendlyElec has released a $35 rival to the Raspberry Pi 3 B+, outdoing the better-known board with 2GB of memory, Gigabit Ethernet, and a more powerful GPU.

The NanoPi K1 Plus follows FriendlyElec's Nano Pi K2, released last year with similar dimensions to the Raspberry Pi 3 for $40.

The NanoPi K1 Plus shares similar specs to the Nano Pi K2 and maintains the Raspberry Pi's form factor, but offers double the RAM, Gigabit Ethernet, and 4K video playback.

The device also has the same 40-pin GPIO pin-header as the Raspberry Pi 3, so it should work with Raspberry Pi accessories and housings.

Instead of the NanoPi K2's 1.5GHz Amlogic processor, FriendlyElec opted for an Allwinner H5 quad-core 64-bit Cortex A53 processor that runs at 1.4 GHz as well as a six-core Mali450 GPU. The Raspberry Pi 3 B+ uses a 1.4GHz Broadcom BCM2837B0, Cortex-A53 ArmV8 64-bit SoC.

The NanoPi K1 features three USB 2.0 ports, one microUSB 2.0 port for power, a microSD slot, while wireless support includes 802.11 b/g/n.

The Raspberry Pi Foundation has launched the Raspberry Pi 3 Model B+, offering a faster CPU and faster wireless throughput than its predecessor, the Raspberry Pi 3 Model B.

Raspberry Pi 3 Model B+ comes exactly two years after the launch of the Raspberry Pi 3 Model B and is in line with Raspberry Pi Foundation's two-year B+ 'evolution' upgrade.

In other words, the changes don't warrant calling it a Raspberry Pi 4, but there are noticeable improvements, including a faster processor, higher Wi-Fi speeds, and faster Ethernet.

The Raspberry Pi Foundation has unveiled a new model of the tiny computing board, the Raspberry Pi Zero W, which adds Wi-Fi and Bluetooth, priced at $10.

In November 2015 the Raspberry Pi Zero was released - a tiny $5 entry-level Raspberry Pi, cheap enough that the Foundation even gave it away free with its MagPi magazine (if you could managed to grab one quick enough). Since then the tiny board has been used in projects from miniature arcade cabinets to electric skateboards, but many of these projects need wireless connections which means adding a wireless dongle and that can easily cost more than the Zero.

The new Zero W uses the same Cypress CYW43438 wireless chip as Raspberry Pi 3 Model B to provide 802.11n wireless LAN and Bluetooth 4.0 connectivity.

Learning to Code

So, you like video games? Do you know that actual humans make video games with some type of computer code? It's true. But even better, kids can write programs too. It might seem scary to get started, but it's really not too bad. If you want to get started, I am going to recommend code.org. There are plenty of learning guides that are appropriate for a variety of ages. Oh, and it's free and online.

Even the lowest level activities are very complete—they even include ideas about functions and debugging. It's the best way to get a general idea of computer programming before moving on to a particular language.

If you want to be more creative with your programming, there is also Scratch (scratch.mit.edu). Scratch is a graphical (and free) programming language that focuses on the control of animated sprites. It's pretty easy to pick up and it's built so that you can share programs and modify others.

Finally, there is one more set of coding activities—physical programming. Physical programming takes some type of code but adds onto it some actual object that the code can control. If that sounds awesome, it's only because it is. There are two physical programming platforms that I have worked with before—Raspberry Pi and Arduino. Although these devices are not free, they aren't super expensive either. Both platforms have tons of great projects that kids (or adults) can work on.

The new feature will allow Pi owners to write Arduino Sketches to interact with sensors, motors, electronic boards and other hardware attached to the Pi's GPIO pins.

Arduino Sketches can now be used to program the Raspberry Pi, marking a moving together of two of the biggest maker platforms.
The cloud-based Arduino Create platform is designed to simplify the creation of Internet of Things applications.
Want to use the $35 Raspberry Pi computer to build your own hardware but only ever used Arduino boards? Well you're in luck.

If you know how to write programs to control hardware using Arduino boards you can now use the same language to control hardware attached to the Pi, the co-founder of the Arduino Project Massimo Banzi announced yesterday.

Banzi revealed a new feature in the cloud-based Arduino Create service that will compile Arduino Sketches — programs typically used to interact with Arduino boards and attached hardware — into a form that can be run on a Raspberry Pi.

The feature will allow Pi owners to write Arduino Sketches to interact with sensors, motors, electronic boards and other hardware attached to the Pi's GPIO pins.

"The idea is there's a tonne of people that know how to use Arduino and they can take their knowledge and apply it to this," Banzi told the Embedded Linux Conference 2018 in Portland in the US.

Pine64 has released a budget-friendly single-board computer with the high-powered Rockchip RK3399 system on chip (SoC).

Available from around $60, the RockPro64 board comes in two flavors, either with the hexa-core RK3399 SoC or the RK3399Pro, Rockchip's first "artificial-intelligence processor". Unveiled at CES 2018, it combines a CPU, GPU, and neural-network processing unit (NPU).

As noted by CNX-Software, a number of RK3999-based boards have been released in the past week but, priced at around $200 each, they've been aimed at business customers rather than home developers.

The RockPro64 with 2GB of RAM will cost between $59 and $65 and will be available from March, while the RockPro64-AI will cost $99 but won't be available until August 1, according to Pine64.

Mettre en place un réseau WI-FI privé n’est pas toujours nécessaire quand vous êtes chez vous bien au chaud à proximité de votre Box et que votre activité numérique consiste principalement à consulter vos mails ou à surfer sur le net mais dans certains cas, cela peut s’avérer très utile. Prenons l’exemple de la domotique qui intéresse de plus en plus de personnes et qui permet de contrôler vos différents appareils électriques à l’aide d’une seule télécommande (ou de votre téléphone) via votre réseau. Dites vous bien que tous ces appareils doivent bien communiquer entre eux et que, dans l’idéal, une connexion sécurisée serait un plus indéniable.

Streaming. Gaming. Networking. Even printing! These projects prove the Raspberry Pi is far more than a toy. Here are 10 surprisingly useful projects anybody can do.
