Hard to tell from appearance only but my initial impression is that's an inductor, not a capacitor. The circuit looks like a switching power regulator. The capacitors would be beige with silver ends, this one looks like an over molded

The concern is that the restrictions would follow the pattern of existing rules around semiconductor equipment and fabricated chips [1]. They are fairly broad and stipulate that US persons cannot transfer technology to any company on an ent

I see now that Section 6.04 explicitly states that if a provider retains any right to use the developed software, they are not allowed to deduct their expenses: > "However, even if the research provider does not bear financial risk

Seems like somewhere in all of this there is an assumption that one writes software to profit from its sales. However, in some cases people contribute software to open source projects that are not only Libre but also "Free as in Beer&q

variable length instructions == CISC is not quite a correct equivalence. The compressed 'C' extention is designed to re-use a lot of the existing decode infrastructure. On RV32 the C instructions are a strict subset of the full le

I can't seem to find any information on Solid Silicon, the company making the CPU. Anyone have a link or more details on this company? The website I can find for Solid Silicon [1] is delightfully devoid of details. [1] https:/&#x

I'm not an accountant, but I think I'm referring to gross profit margin [1], which is revenue minus cost of goods sold (which is small for an IP licensing company, any company that actually sells hardware will be a fraction of tha

Total revenue: 2.679bb Gross profit: 2.573bb (page 18, FY2023) 96% gross profit margin? Ahh to be an IP licensing company....why would anyone invest in building physical things when there are opportunities like this out there! </s&g

Perhaps a charitable interpretation of that statement is "there are years of work to go from a proof of concept to a usable product". Even if LK-99 is some kind of a superconductor, there are a whole host of daunting technical iss

Looking at the court documents, it seems shady organizations registered a bunch of domain names that are used in the trade of brand-name athletic gear. The victim's identity was used to register one of those domain names, but just look

I have used the NUCs to integrate controllers into small robotic platforms and custom lab equipment. They are a good 'it just works' platform that you can scale performance v cost over time as needs vary (need image processing? dr

It's also been a while since I stepped foot in a fab, but my impression is that for modern processes there are no people in the fab proper. It is fully automated, people sit outside the fab or they service machines in drop-down bays un

Kinda ironic how the article is about chiplets, but all the factory photos are of an old school wire bonded PGA packaging line... But maybe that's the point, you can't find a chiplet factory within the borders of the USA to photog

Except in manufacturing, getting your yield up and tuning a process is basically 'just work'. You define a space of parameters you want to explore and then you brute force it by building samples at each parameter step and then ana

But if you don't happen to believe in God then swearing on a book of (from the oath takers perspective) fairy tails is equivalently silly / virtue signaling. I think it's better if someone calls out that they don't belie

Wow! someone is still using a chumby 8! I designed the hardware and some of the firmware... if you get stuck I might have some old notes laying around somewhere still, happy to share them. But from the looks of your post, you've figure

Just adding on to taniwha's correct comments -- it is possible to indirectly image the charge using thermal stimulation of the laser to induce the Seeback effect. The local heating will cause the current consumption of the chip to shif

His images are great! Discovering his photofeed was one of the puzzle pieces that sent me down this path in the first place. I give him a shout-out in the post :)

Hi! thanks, I'm the post's author. I had the same concern you have about finding "just the right lens", but was pleasantly surprised to find the $180 camera/lens combo linked in the post worked just fine. In fact ba

What I don't get is the risk of an accidental signal triggering it. The system as described sounds similar to some existing tech used to communicate with submarines when they are under deep cover... presumably those comms come with bot

I find trackpoints are more precise for CAD work. You can end a gesture with zero force precisely; but letting go of a mouse button inevitably has a tiny bit of positioning jitter. I use the track pad to scroll, and the trackpoint to draw.

Stealth mode simply refers to a stage in a company's evolution, not an on-going state of operation. For example, because the company is not yet fully formed, it doesn't have a website -- nobody has made one, because it's not

One goal of an open-SDK SE is for all the base primitives to be open, precisely because stuff like GG-20 gets broken. I don't think it's realistic to think that we're at a point where we could burn such a novel and complicate
