PC makers are getting desperate for memory chips.

Whether you’re a seasoned electronics engineer or just starting out as a hobbyist, it’s a good idea to have a few all-in-one development boards on hand. When inspiration strikes, the last thing you want to do is spend weeks designing a circuit and waiting for the parts to be shipped to your door. You want to strike while the iron is hot and turn that great idea into a reality. By integrating many commonly used components into a single package, all-in-one boards make prototyping fast and easy.

If you could use a new all-in-one board in your toolbox, you should take a look at the ESP32-S3 4.2-inch RLCD Development Board that was just released by Waveshare. It combines a powerful microcontroller with a very unique display technology, along with plenty of options for interfacing. Currently, the device is selling for just $27.

CXMT and YMTC are scaling fab capacity as AI demand strains global supply.

PicoIDE is a convenient alternative to worn out old drives and media priced from $69.

These parts have the least number of failures in Puget System's builds.

Redragon is known for its budget gaming peripherals, and it has recently announced three more additions to the line-up, this time catering to both gamers and productivity users, with two num pad-toting mechanical keyboards and a wireless gaming mouse. Starting with the latter, the Ebony M998 STD is a tri-mode wireless gaming mouse with a mild ergonomic shape and powered by the PixArt PAW 3311 sensor, which means 24,000 DPI, up to 300 IPS speed, and 35 G acceleration tracking capabilities and 1 kHz polling. It weighs in at 61 g, and is powered by a 400 mAh battery. Redragon says it should last 34 hours on a single charge, but does not cite test conditions or connectivity mode, so your mileage may vary. Probably the most interesting part of the Ebony M998 STD is its magnetic charging dock, which charges the mouse with pogo pins, not wireless charging, and doubles as the 2.4 GHz receiver. While it's not using a flagship-tier sensor, it also does not command flagship prices, coming in at only $29.99 from Redragon directly. The mouse can also be customized on Windows with proprietary software, and it supports on-board macros and rebinding. Redragon also doesn't specify which switches are being used in the Ebony mouse.

Norm Jackson and colleagues at Thort Werx are looking to put a low-cost mixed-signal oscilloscope and logic analyzer on every desk, turning to a pair of Raspberry Pi Pico 2 microcontroller boards to power the Picotronix — opening for crowdfunding soon.

"We've built a dual [Raspberry Pi] Pico 2-based mixed-signal capture system (oscilloscope + logic analyzer) using MicroPython and PIO/DMA [Programmable Input-Output/Direct Memory Access] in the RP2350," Jackson tells us via email. "The project highlights many of the amazing features of the RP2350 and advanced techniques to build real time complex designs using MicroPython."

More information is available on the Picotronix website; a Kickstarter campaign is planned for the near future, with pricing estimated at $99 without or $129 with LCD and $9–49 per picoPod, and interested parties are invited to sign up to be notified when crowdfunding opens.

This might just be the most overengineered desktop gear I've ever come across. The Naya Connect system features four devices built around a modular keyboard to upgrade your setup with all kinds of shortcuts and tactile inputs.

In space, no one can hear you scream how good this cyberdeck is!

Better watch out, Frore.

Soon enough, you might not even be able to buy a calculator.

Isn't a "click" just physically making two connectors touch so that a circuit is made to send the signal of an action? There doesn't have to be any noise associated does there?

For example, if we used 2 springs, one to hold up the button and another to make the contact with the circuit, the click would be silent. Or maybe something already exists that I can swap out into my mouse?

Nvidia is among those to blame, says Nomura Securities.
