ESP32-C3 AWS IoT ExpressLink module & devkit aim to ease connection to AWS IoT services - CNX Software
The compact (16.6 x 13.2mm) ESP32-C3 module is currently offered as part of the ESP32-C3-AWS-ExpressLink-DevKit development board following the Arduino Zero board form factor allowing it to be plugged into the Arduino board, or easily connect to other host systems such as the Raspberry Pi. The goal is to simplify the deployment of IoT solutions removing the need for developers to maintain complex firmware, and offering end-to-end security and fleet management out of the box.

Wake-Up Robot Does It Gently | Hackaday
For hundreds of years, people have fallen asleep while reading in bed late at night. These days it’s worse, what with us taking phones to the face instead when we start to nod off. At least they don’t have pointy corners like books. While you may not want to share your bedroom with a robot, this wake-up robot by [Norbert Zare] may be just the thing to keep you awake.
Here’s how it works: a Raspberry Pi camera on a servo wanders around at eye level, and the Pi it’s attached to uses OpenCV to determine whether those eyes are open or starting to get heavy. The bot can also speak — it uses eSpeak to introduce itself as a bot designed not to let you sleep. Then when it catches you snoozing, it repeatedly intones ‘wake up’ in a bored British accent.

Is It Finally Time For Christmas Decorations? | Hackaday
[Arnov] is trying to get into the holiday spirit and is doing so the way he knows how. He was thinking of some cool decorations for his Christmas tree and decided the best decorations are the ones you make yourself, so he made his own blinky Christmas tree ornament.
The famed “blinky circuit” is certainly one that we are no strangers to here at Hackaday. Some of our readers will be very pleased to see that he did in fact use a 555 timer and not an Arduino. The 555 timer is wired to drive the clock pin of the CD4017 decade counter and the outputs of the decade counter are wired to the LEDs. The LEDs are lit up sequentially upon each low to high transition of the clock pulse though you may try getting creative with your LED wiring scheme to achieve different blinking effects.

Finally, A Use For Old Cellphones | Hackaday
In what is now a three-year long search, I’ve finally found the perfect use for an old cellphone. And with it, the answer to a burning question: Why aren’t we hacking cellphones?
First, the application. The Octo4a project lets you use an old Android phone as a 3D printer server, web interface, and even time-lapse camera to make those nice movies where the print seems to grow up out of nothing before your eyes. It’s the perfect application for an old phone, making use of the memory, WiFi, graphics capabilities, and even the touch-screen if you want local control of your prints.
Connecting to the phone was the main hurdle that I’ve always seen in developing for cellphone projects, because I have robotics applications in mind. But Octo4a gets around this with low or no effort. Most 3D printers are designed to run on USB anyway, so connecting it to the phone is as simple as buying a USB OTG cable. With the USB port taken over, powering the phone long-run becomes a tiny problem, which can be solved with a Y-cable or a little solder. Keep the OS from going to sleep, somehow, and it’s problem solved!

Samsung, Red Hat to Work on Linux Drivers for Future TechThe metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. |
