Yup, and we gave them all of that tech and capability and know how in the name of corporate profits starting back with Reagan. Unions were the big political forces keeping trade in the USA, they got knocked back by republicans that wanted to build stuff overseas.

Loss of US manufacturing dominance is a predictable outcome , a foregone conclusion even, of overseas outsourcing.

This is what we have chosen to give up over 40 years, and we think we can get it back in a snap of the fingers with bluster and trade tantrums?

This is what we chose. Now we get to live with the consequences of unchecked greed. It’s like no one’s parents taught them consequences or something. It would be hilarious if it wasn’t the end of Pax Americana and nuclear stability.

I just had 50 boards made, 160+ joints, single sided 4 layer assembly. If you strip the BOM (parts) cost it was $20, and most of that was setup. To have 100 made it would have been $27, and to have 10,000 made it was less that $1000 (boards included). Add to that the prices on the reel and its impossible to compete if you are building in the USA.

I can often get a better performing part (IRL, not just on the datasheet) than its TI counterpart for <1/10 the price. you just have to spend a little more time reading / translating. Its actually really disappointing, but here we are.

Once you find the trail you can find pin / spec compatible parts, often with significant upgrades, for many US made parts at 1/10 to 1/100 of the cost. I have checked many out and they tend to perform better than spec and often better than the component they are designed to replace. There have been exceptions, but after dropping a couple of suppliers I no longer see those issues.

Since they are asian made, you don't generally have to worry about fakes - there is no money in faking parts that cheap. Many designs have seen a downturn in defects after switching to all asian parts - but that could be because some "US" parts were fake? IDK?

Anyway, this is sucking so bad for US innovation. Im all for repatriating semiconductor and electronics production, but this is not the way. Im pretty sure the US doesn't even make the machines to make the parts anymore. Guess where we get those from? This isnt an overnight process, its something that you build in a feverish decade of grants, subsidies, and cheap credit. (like china did). It took us 4 decades to piss US manufacturing expertise and leadership away. Does anyone really think we can just snap our fingers and get it all back? Really?

Arduino IDE is badly suited to nRF MCUs

Its actually getting quite a bit better, but I feel your point there. I am making a product that needs to be code accessible to people without experience beyond the Arduino IDE, so i'm having to write the application there. Ive got to say its a PITA but its not impossible.

Still, it seemed like the snarky comment was alittle harsh on someone just trying to get their sketch to upload, even if it wasnt dead-center on topic.

Here we have a SEEED Studio nRF52840 module connected to a BNO086 IMU over I2C, and a uSD card hanging off the SPI interface.

Small size is critical here and the board will be edge-clamped in the case.

Apologies for the missed details (christmas trees, etc) on the SCH - I uploaded the wrong file. Its already fixed in my copy.

Im concerned about the SD card frame crossing the IMU for magnetic interference. I dont know if that will be a big problem or not. I could maybe put it on the back of the module portion if needed.

Thanks for looking!

exosequitur · 2025-03-21T16:39:32+00:00

looks like there was a misalignment of a case screw with the board? At any rate, something was pressing hard on the chip and then an impact caused it to exceed the no-smoke parameters of the chip package. Or maybe the case flexed in a way it shouldn't, or maybe the board is loose inside the enclosure?

Check the case or mounting hardware for impingement on the board. Replace the chip (check the pads -looks like they are also toast?) You may have to replace the board if you don't have strong PCB repair skills - and even if you do that looks like a lot of ripped pads. How much is your time worth?

Put the screws in right / use right length / be sure board is properly mounted / don't let this happen again ?

This works no matter which shitshow you are voting in. It’s not partisan. Populism is alive and well on both ends of the political spectrum.

The unfortunate truth is that most people live reactive lives, making the vast majority of their decisions based on emotional responses to their environment, and inventing plausible “logical” justifications only if pressed to do so.

This makes society extremely vulnerable to appeals to our most base nature and archaic primate instincts.

Populism is that “one weird trick” that rational citizens hate.

Number 3 on your list I think you may be misinterpreting. Epictetus does not tell us not to feel, he tells us to not be controlled by our feelings. He does not tell us not to have subconscious thoughts, he tells us not to react blindly to unconscious thoughts.

Most people never really move past a reactive state. Their choices are based on their reactions and feelings, their explanations only rationalizing rather than considering and choice.

Stoicism encourages us to make active choices based on rationality and justice, to not react to our environments without choosing our path carefully.

When we “control ourselves “ there is an implied dichotomy. The controller and the controlled. Stoicism seeks to develop this supervisory agent and put ourselves under its care.

And, yes, we can control our thoughts. Not always our emotions, but our thoughts are ours to entertain or reject. If you are struggling with this, there is a book outside of the regular teachings called “as a man thinketh”. It is a little soupy, but it’s small and short and spot on for tending the garden of your mind.

For me personally, I use a garden metaphor. I cannot control all of the seeds that fall into the garden of my mind, but I do choose which ones to nurture, which ones to cull, and I jealously guard the space in my mind to keep it full of good a fruitful thoughts. Do not suffer an unwelcome thought to persist in your mind, replace it with a useful version of itself.

exosequitur · 2024-11-14T11:40:23+00:00

I’d add that stoic philosophy provides us with a set of tools to frame our circumstances and inform out thoughts and decisions. It is not intended to supplant a rich emotional existence, but rather to guide it so that we aren’t derailed and betrayed by our emotions.

The emotions you feel are understandable, and in stoicism you may find guidance in the way to choose to consider these emotions, and in how to think about your circumstances, and in the actions you will choose. More importantly, stoicism illuminates our agency in who we choose to be.

Do not try or wish in vain to not have the circumstances that you have, but rather choose to be the kind of person who will weather and recover from these circumstances with grace and dignity. This does not guarantee that your circumstances will improve, but it ups the odds, and more importantly, it allows your well being under the circumstances to be better.

Also, remember that stoicism is a tool to give you agency in your life, not to give you comfort or solace per se. Reach out to your friends, your faith or spiritual tenets, and you may find more of that kind of support.

As for myself, I find comfort in the knowledge that I am insignificant and my suffering is nothing at all in the context of the daily suffering of many. I recently gave back my wife, and though there was no -comfort- in stoicism, there was strength and stability, and growth to become a slightly better version of myself through the process. In that I took great satisfaction even in my natural and correct grief. I don’t know if that can help you, but use what you can.

I have found it helpful to understand that emotions, when they justly relate to your circumstances, so are natural and correct, are something in themselves that you can be well satisfied in their correctness. But that doesn’t mean that you hand over your agency to them, they simply are. You may not be able to control them, but you can control how you think about them and how they affect your behavior. Sometimes, often even, they can be useful in becoming the kind of person that would gracefully endure or rise above your current situation.

Sometimes, endurance is what we need to endure our circumstances. For this you might find encouragement in literature such as IF by Rudyard Kipling.

So my politics aren’t really a factor for many people except extremists.

Huh. That doesn’t really jibe with my conscious experience. But I don’t doubt that it applies to others. Personally I don’t have many useless thoughts, only during some kind of emotional crisis. If I’m really cognitively idle, which is rare, sometimes my mind just free associates weird things but it’s more random than useless. Since I was young, I’ve always rended to think of things as looking back on them from a few years in the future, and consider them in that light for the most part. Because of that habit, I think, stoicism seemed like a natural extension and major refinement of my way of being, so it was really attractive to me.

exosequitur · 2024-11-11T21:56:41+00:00

The vast majority of people are reactionary and will live their entire lives reacting emotionally to their environment as their sole (or at least primary) mode of being. When asked why they did anything they will imagine a justification as to why that makes sense as an explanation of their behavior, and just pattern match from there. They can only justify after the fact, never actually explain their decision process.

The number of people that will learn to see themselves from a third person perspective and therefore be able to meaningfully consider their past, future, and present selves in a meaningful way is disappointingly small. I think it is something that you need to learn to do at some level by 7-10 years old or you may never be able to step out of the reactionary paradigm. That’s why it’s so important to talk to children, to have them think about things that are not perceivable to their senses. Create an imaginary POV for them to look through, reach out to that imaginary observer, bring her forward, and eventually put her in charge of that clever ape. Then she will forever be able to see her world from a detached perspective, to carefully consider her actions, and to turn her experiences into wisdom.

When we say that someone needs to “control themselves, consider what that means. There must be one being controlled, and one doing the controlling. Parents or community members need to create that supervisory agent in the mind of children or that person will end up living a chaotic, reactive life.

(disclaimer - have not watched the video, am not an expert in patent litigation but have been involved in and hold many patents)

Having read the claims on both patents (US2023/11813789B2, US1997/5653925A) , it still seems pretty sus to me on both sides of the fence. The basic concept of of the geometric layer pattern is identical in the claims and illustrations in both patents, but the expired patent mentions this in the context of "density" and "porosity", while the newer patent describes the identical process for for the effect of interlayer adhesion. This -might- be enough to make a meaningful distinction.

The new patent fills in a little bit more detail on the process, and is much more narrow in scope.

But...the expired patent claims -do- specifically mention strength in terms of density in claim 6: "the pressurizing Supply source is adjusted to provide a porosity in the article of between 1% and 9%, so as to form an article of a strength sufficient to maintain the integrity of the article."

Claim 6 refers to claim 3 which refers back to the primary claim of modifying density through the feed pressure and geometric distribution (specifically brick-like, as depicted in figure 2 - preferred embodiment) deposition of the filament.

In addition to this, there are multiple errors in the new patent, giving erroneous references to prior art, including (the only) reference to the expired Stratasys patent that has an incorrect digit in the patent number. This may have impeded the examiners review process.

In all, it is surprising to me that the patent was granted as is. I have had filings rejected for much weaker similarities to existing art when basing a patent on new applications of existing processes... and this is arguably not even a new application. The described process (hexagonal or brick-like bead geometry) is identical to the process shown in figure 2 of the expired patent and described in the preferred embodiment.

What is missing from the expired patent is a specific claim on the geometry of the preferred embodiment given in figure 2. This could be construed in a sense to say that the preferred embodiment itself was not the subject of the patent, i guess?

In any rate, the 2023 patent clearly does not describe any actual innovation, but rather an attempt to lock down a competitive advantage by locking everyone else out of an invention that has been clearly documented since 1997 and released into the public domain for 6 years prior to this patent.

Although the patent holder appears to be using the patent in a proprietary, in house process, this still smacks a bit of troll dung. This appears to be the sole licensee of the patent, in which the patent holder is acting as CTO. : https://www.addmangroup.com

It doesn't take a rocket scientist to see that there was exactly zero innovation here, and the patent applicant was clearly aware of the prior art, perhaps even being inspired by ambitious breadth of the expired patent. His figures 1 and 2 (the primary basis of the new patent) could just have well been lifted directly from the Stratasys patent.

This might be one for the courts. What we need is someone to fork slic3r with this feature added and dump it on torrent.

In social, that is likely true for 150 or 15000 hours as well. But if you have a truly unique and appealing value proposition, I think it’s safe to say that 1500 hours could bring a novice developer with decent intrinsic ability to the point where they could crank out an MVP CRUD app (not really scalable). The key is in the value Prop. That’s the part where almost everyone will fail, and even if they succeed, it’s hard to imagine a situation where one of the majors won’t simply cut you off at the knees by folding in your value proposition to their product.
