For the layman, 0 degrees celsius is also a good proxy for the distance to "room temperature" superconductor.

AFAIK the Section 301 tariff (and increases) only applies to parts imported from China/HK. There are lots of manufacturers on DigiKey that make their parts from elsewhere where the…

Consider a scenario where you're editing a function: function foo() { return a*2.1^2+0.52/2 } So you do a find-all regex "1.*5" and delete all matching occurrences (à la CRISPER) t…

While it might be hard for the US to make lithium batteries that are competitive economically, there are still many countries in the world that can make them economically that are …

From the article's opening sentence, it's clear that they are being sanctioned for doing business with Taiwan's Fire Agency, and not for any military reasons. A few weeks ago, Chin…

Sanction aside, this action is a wake-up call for all US based companies operating in geopolitically sensitive industries that they absolutely need to diversify their supply chain …

The actual paper describing the construction of the MUSE Stellarator: https://www.cambridge.org/core/journals/journal-of-plasma-ph...

I want to clarify that they actually did build a transistor-like device, and not just hypothesize about it. I missed section 3.2 when I initially skimmed the paper, which demonstra…

It looks like the editors have amended the title of their article since this was initially posted. The original title was just “3D-printed Active Electronics”

Reading the article, it looks like so far they only have a working resettable fuse (a passive device), and only hypothesize that a transistor was possible with the copper-infused P…

They made a video that explains how to navigate the roundabout, and shows what it will actually look like (with yield markings)[1] [1]: https://youtu.be/07_m7HHiZRw

Yep, they explicitly call out that the onboard voltage regulator can work with a single lithium ion cell.

You're right, after re-reading the Power section on the datasheet it seems connecting 5V to the VREG_VIN should suffice to power the digital domains, but if you want to use the ADC…

Edit: See comment below; The RP2350 can be powered by a 5V supply.

Why Germany? Both Netflix and Broadcom are American companies, so isn’t it more logical to pick a venue in the US? Was Broadcom’s case so flimsy (with regards to US patent law) tha…

The alternative is to do what JS does: https://www.destroyallsoftware.com/talks/wat

The STM32 F0/G0/C0 lines come to mind. More I/O, more peripherals and built-in flash. For hobbyist levels, buying 1-10 pcs they are comparable in price to an RP2040 + SPI flash. Ho…

Also you could potentially damage the on-board voltage converter/regulator, since most aren’t designed to be back-driven from their outputs.

He also has a video on YouTube for Conical slicing (for those that prefer watching videos): https://www.youtube.com/watch?v=1i-1TEdByZY
