Librem 5- Device Overview - Purism
Librem 5 phones are for those who care about their digital security and the use of free and open source software. Our team has designed the phone so that the parts are easily repairable and you can keep using the same phone for a longer time. Let’s go through the hardware of the phone.

This gorgeous headboard simulates sunrises | Arduino Blog
The world would be a much better place if everyone could wake according to their own natural circadian rhythm and natural sunlight peeking through their window. But the world doesn’t work like that and many people have to force themselves awake. That’s especially true for people who don’t have conventional work schedules and this gorgeous Artificial Sunrise Headboard gives them a pleasant wakeup call.
Consider how our ancestors woke up before artificial lighting came along and humanity was still nomadic, because we haven’t evolved much since then. As the sun started to rise, the sky would transition from black to dark blue and then continue to lighten over the course of an hour or two. That provided people with gradual stimulation to ease them from sleep into wakefulness, which stands in stark contrast to the sudden, blaring alarms that are common today. This headboard simulates the gradual sunrise and an integrated personal assistant brews coffee to give sleepers a little extra incentive to get out of bed.

James Burton is giving legs their snakes back | Arduino Blog
James Bruton gave that title to his most recent video as a good-natured jab at Allen Pan’s project about “giving snakes there legs back.” In Pan’s video, he built a robotic exoskeleton to let snakes walk around on motorized legs. But as Bruton noted in his video intro, those legs didn’t look very snakelike. So Bruton created his own robot that walks around on more serpentine limbs.
This robot’s six limbs each have three degrees of freedom (DoF), all of which are motor-driven. But unlike most robotic limb designs, these use “oblique swivel joint mechanisms.” That mouthful of a term means that each joint rotates on a plane offset at an angle relative to the preceding joint. While that arrangement isn’t suitable for many applications, the kinematics are interesting and the resulting movement does resemble the wriggling of a snake’s body as it slithers along.

Olimex ESP32-C3-DevKit-Lipo is a tiny RISC-V board with WiFi 4, Bluetooth 5.0, and a LiPo battery charger - CNX Software
Olimex has just launched the ESP32-C3-DevKit-Lipo board based on ESP32-C3 RISC-V wireless microcontroller offering WiFI 4 and Bluetooth 5.0 connectivity, some I/Os, as well as USB and JTAG.
As its name implies, the board can be powered by a LiPo battery and charged through a USB Type-C port. It offers up to 15 GPIO for expansion and comes with an ICSP connector in case you need to reflash or debug the bootloader through a JTAG interface.

Can you become the next Trombone Champ? | Arduino Blog
The first Guitar Hero game hit shelves in 2005 and kickstarted the rhythm game revolution. While it wasn’t the first rhythm game, its inclusion of “realistic” guitar controllers changed the industry. It wasn’t long before competitor Rocksmith took things a step further and let players use real electric guitars. But guitars are so common; if you want to stand out, you go for the brass. That’s why Greig Stewart (AKA Theremin Hero) built this custom controller for the Trombone Champ game.
Trombone Champ is currently enjoying viral attention thanks to its quirkiness. To play the game, the user drags their mouse cursor up and down to mimic moving a trombone’s slide and clicks their mouse to blow air. Like Guitar Hero and most other rhythm games, the goal is to hit the notes with the most accuracy possible. But Theremin Hero correctly surmised that moving a mouse is nothing like playing a real trombone, so he converted a cheap trombone kazoo toy into a controller for Trombone Champ.
