21st Century Innovative Technologies and Developments as also discoveries, curiosity ( insolite)...

Si les Raspberry Pi ont fait du chemin depuis le tout premier modèle de 2012, leur principe est resté le même : de petits ordinateurs à tout faire très bon marché. Le Raspberry Pi 5 tout juste dévoilé répond à ces critères en y ajoutant un surcroît de puissance.

Quatre ans après un Raspberry Pi 4 qui a connu un très gros succès (en partie dopé par la crise sanitaire), le Raspberry Pi 5 se doit de ne pas décevoir ! La fondation qui développe et produit l’ordinateur a mis les petits plats dans les grands, en promettant des performances CPU et GPU de deux à trois fois plus élevées que sur le précédent modèle, avec deux fois plus de mémoire et de bande passante pour les entrées/sorties.

Surprise! Details of the Raspberry Pi 5 are out, and while you can't get your hands on a board just yet, you can bask in the new features and improvements.

At the top of them is a new chip, designed in‑house in Cambridge, UK. 

The Broadcom BCM2712 quad-core 64-bit Arm Cortex-A76 processor is three generations ahead of the one used in the Raspberry Pi 4, and is not only faster than the old chip -- between two and three times faster -- but it also consumes less power, which in turn should mean it runs cooler.

Here at Arduino we are thrilled to announce a new, revolutionary revision of the iconic UNO board, which will expand the concept of the open-source brand’s most iconic and popular product while providing the maker community with a long-awaited update on performance and possibilities. The Arduino UNO R4 indeed preserves the well-known features of the UNO family – standard form factor, shield compatibility, 5V operating voltage, outstanding robustness – while offering no less than a 32-bit Cortex®-M4 and a 3-to-16x increase in clock speed, memory and flash storage.

On Thursday, BeagleBoard unveiled PocketBeagle, a tiny, open source, USB key fob computer that works as a development board for both beginners and professionals.

PocketBeagle—which, at 35 x 56 x 5 mm, is smaller than a credit card—features a simple, open source hardware design, and a catalog-available, well-documented processor, according to a press release. This board can replace some costly hardware, and also offers a solution for rapid prototyping without slowing the path to production, which can lower risk as well.

This low-cost Linux computer offers "tremendous expansibility," according to the release. The company also offers the chance to learn programming from online educators.

For hobbyists, "PocketBeagle is small and flexible enough to fit in gaming, 3D printing, robotics or other electronics projects; and affordable enough to dedicate one to live permanently in each of those different projects," according to the release.

"PocketBeagle not only includes a 1-GHz processor, but also industrial-oriented peripherals and microcontrollers optimized for interfacing to the physical world," the release stated. This could also make it a good option for Internet of Things (IoT) experiments, especially in businesses.

Die Raspberry Foundation erweitert das Sortiment an Bastelrechnern um ein weiteres Produkt. Das Raspberry Pi Pico W ist ein kleiner und günstiger Microcontroller für diverse Projekte. Das Platinendesign lehnt sich an das Raspberry Pi Pico an. Allerdings unterstützt das Pico W 2,4-GHz-WLAN über einen Onboard-Chip. Parallel dazu gibt es den Pico künftig auch als H-Variante mit bereits vorinstallierten GPIO-Steckverbindern. Damit sind Bastelprojekte ganz ohne zusätzliche Lötarbeit möglich.

Fabricating a circuit board isn’t tough but it takes a while. The back and forth, the bugs, and all of the shipping costs can turn a small project into a big problem. That’s why Botfactory raised $1.3 million to stick a PCB printer on your desk.

Founded by NYU grad students Nicolas Vansnick and Carlos Ospina along with NYU professor Michael Knox, BotFactory came about when Vansnick and Ospina needed to make a PCB for a class project. Nearly every student in the class failed because they couldn’t get circuit boards made in time and each iteration took weeks to complete.

“This lesson was tremendous – if this was a problem that was typical for any project, then the solution would revolutionize how electronics could be prototyped and fabricated,” said Vansnick. “Up until then, everybody had been trying to miniaturize electronics and chips, but not the processes that are employed to create PCBs.”
