aftermarket stuff

#

although when it comes to nano - not sure

#

I can't wait for graphene batteries though

#

They would be perfect with apple devices, since you don't want to open them as much

delicate stream
#

Aftermarket batteries can be hard... I got a few duds trying to replace my Nexus 6P battery

late fulcrum
#

If it becomes a problem, I'll probably either just remove the battery and power it from the car's electrical system, or replace it with a micro SD card.

delicate stream
#

Some devices can't boot without the battery, which sucks...

manic tide
#

I have some android phones with batteries lost that I may like to boot

frigid tiger
#

I've had it with my macbook, apple products do not "just work" and when they don't work troubleshooting them is a practice in futility that inevitably leads to RMA

tardy badger
delicate stream
#

Thankfully my MacBook Pro hasn't had too many problems... I had an issue with the keyboard, which was actually under recall, and they replaced the keyboard, which is basically the entire top of the laptop AND the battery, for free. It was nice to get a free fresh battery 3 years in, lol

tardy badger

Lol

#

So they won't just take a 3.7-4.2v source to the battery pins

manic tide
#

Yeah, what's bad about smartphones as "miniPCs" is that they don't accept standard interface, like regular sized computers

#

cause I have some phones with broken screen

delicate stream
#

It would be nice if you could just connect HDMI to any phone via the USB port...

late fulcrum
#

I kind of liked the Atrix Dock concept, were you could add a bigger battery, keyboard, screen, and touchpad to your phone by plugging it into the dock. Now I use that dock to make a Pi into a laptop

manic tide
#

oh, just like asus fonepad

delicate stream
#

Intel had a concept where the core components [primary CPU, RAM, storage] were in a thing roughly the size of a 4-stack of credit cards, and you could slot it into a phone, tablet, laptop, or desktop shell, and each could provide it with varying capabilities... I wish we had something like that. You could upgrade the shells to get more advanced capabilities while keeping the core, and every now and then upgrade the core itself to go even further

frigid tiger
#

I'd love to use my phone as a PC, the tech isn't ready I guess

late fulcrum
#

There's a modular phone concept like that but it keeps running into reality

delicate stream
#

Depending on what you mean by "as a PC", it's there... Samsung has Dex, so you dock your phone to get a desktop-like experience. You can do all the basics, browse the web and word processing and whatnot, but you're not gonna render 4K video edits on it

frigid tiger
#

ya at the minimum I'd need to compile code on it and dock it

late fulcrum
#

I do use my phone as a terminal, which has been handy on a few occasions

I had been watching the Fairphone for a while.

delicate stream
# frigid tiger ya at the minimum I'd need to compile code on it and dock it

For basic stuff like that, phones have the processing power. It's just a matter of whether the manufacturers gave it the capability to do video out via USB, and if they enabled anything like that in software. Some devices have the PHYSICAL capability to output HDMI via USB C, but there's no software support, so it just doesn't work.

do sbc manufactures follow some sort of standard of size? I see like that 3.5 inch boards have wide different sizes

#

Looking at the acquisition announcement the company I work for made this morning, I sit here and wonder.. how big of a raise or how big of a bonus would that turn out to be if it was used to retain employees vs acquire and consolidate the industry

late fulcrum
#

My guess is "enormous", but since it doesn't benefit rich old white guys, it's not going to happen.

burnt tendon
#

I mean, it's not like other CEO type people aren't as.... you know... as the one in the news. It's just most of the time they manage to not be unfiltered and in front of the press.

tardy badger
#

If you want to know what company CEOs really think, listen to quarterly board meetings.

#

Or go to a company all hands and here off handed excuses about why we can make huge acquisitions but not give raises that match inflation

burnt tendon
#

Oh yeah, no that's still coached.

frigid tiger
#

Paying employees enough to afford living expenses is bad for the economy

whole jacinth
#

"the economy" is often rich people code for "share prices of stuff i'm invested in"

tardy badger
#

We were told we’d get around a 4.5% raise in the spring for annual merit increases

#

And inflation is checks notes over 7% still

burnt tendon
#

At least in software folks can get a commesurate-with-inflation raise generally by hopping jobs.

tardy badger
#

My rent will surely go up in May, I’m guessing at least $100, if not up to $300

burnt tendon
#

But not by getting a raise. Then wonder why nobody stays around and everybody has to retrain all of the time?

tardy badger
#

I boosted my salary $20,500 by leaving my job, getting laid off from my new job, and then going back to my old job making $3k over what I made at the job I was laid off from.

#

And now I’m talking to a company that’s willing to pay me at least $10k over my current salary. Software is fun. I’ll probably top out around $160k in a few years

burnt tendon
#

I was thinking this morning that, while the old white dudes who provide the circle around the average CEO and help make him sound reasonable and set achievable goals do frequently pull down money in the order of millions, yet it's still fundamentally unfair because they have to play nice with the billionaire who, if left to swing in the wind, would sound like a complete fool, but somehow keeps growing his wealth by billions.

tardy badger
#

Yeah, i like to call it the billionaires paradox

burnt tendon
#

Like, why can't I get a few billion to build a super-rocket? I can provide just as much actual value as those other guys!

I believe most people would try to be philanthropic with the proceeds of success; yet our global society tends to promote people who hoard instead

dusty citrus
#

Nobody's got a great new idea to replace the old idea. Our legacy situation (the present) comes from, I think, an entirely different set of selection pressures.

tardy badger
#

We want kings, not freedom you say?

#

torches, pitchforks > wrong changes

#

I'm saying it's not a spaced ruled by the best ideas.

tardy badger
#

Chinese society really is an interesting change from the norm because historically, their identity is based on unity and collectivism.

#

And from that, a small group of people convinced them over time that authoritarianism was the best system to protect that identity.

#

It’s cool how different systems emerged simply because of geography

"if we could all just be japanese we'd solve our problems overnight." ;)

#

My nephew went for six months in college. Threatened to get serious about learning Japanese.

A thought keeps bothering me.

tardy badger
#

Yeah..

#

My work is heavily influenced by how much a committee thinks we should spend on IRAD

#

So I run out of irad and program work frequently and end up on internal technical tasks

#

Which makes me feel like I’m not all that valued

#

And then i start getting bored and entertaining recruiters šŸ˜›

#

Different one

tardy badger
#

Oh sorry, thought you were following the current conversation

manic tide
#

Yeah

#

I've had this thought for a week

#

Even though it's a PC market related one, for me it feels to better ask here, among friendly people.

#

From what I've got from an LTT video, you might as well just upgrade your whole computer instead of buying just a GPU

burnt tendon
#

Oh yeah, I went to Japan when I was a little 2nd grader and it was quite a thing. I need to go back.

tardy badger
#

Depends I guess. If you’re buying a prebuilt computer, probably

lusty fossil
#

I just upgraded from year old hardware. I haven't had a chance to install an OS yet tho so it's just sitting there until this weekend

#

5 year*

tardy badger
#

For me? I have pretty recent hardware from late 2021, so getting a GPU would make more sense than a whole new computer

burnt tendon
#

And, heh, my chassis is from 2000 or so and at this point, it's a source of perverse pride that I'm still using the same old chassis.

manic tide
#

I'd like to get everything separately. Something like a Ship of Theseus gonna happen on my desktop

#

I was given a pretty cool lenovo OEM with i5 6400

#

Only thing proprietary I think is the PSU. It's only designed to power the motherboard.

I think I’ve got a Ryzen 5 5600X

I know for sure it’s a Ryzen 5 5600, just don’t remember the exact letter after šŸ™‚

# tardy badger Tis expensive to visit though. Last I looked, like $2500 a plane ticket

That can be improved by clever purchasing. It turns out that Hawai'i is a popular tourist destination from Japan, and Las Vegas is a popular tourist destination from Hawai'i. So the trick is to find a cheap flight to Vegas, then a backhaul flight from Vegas to Hawai'i, then a backhaul flight from Hawai'i to Japan. It takes some persistance and patience, but the available savings are staggering (one time I got a redeye from Vegas to Hawai'i for $67).

#

As for computer upgrades, I just upgraded by Jetson with a Coral TPU. Granted, that meant removing the WiFi module, but that's okay.

tardy badger

I see you could save ~$1200 flying SFO—>Oahu—>Tokyo

I keep telling myself I should design a Lithium balancer so I can stop monkeying around and using single batteries with a boost converter, but I hem and haw like always, and convince myself "dis is da wae" and end up using single batteries with a boost converter.

I only need to design something thats good for 3S or 4S batteries. Yea, I know the cheap modules exist (I have a few). But I do like the idea of rolling my own.

delicate stream
#

I'd use the cheap ones as examples -- they're usually pretty simple, so you can look at them and see what you like and if there's anything you want to add/change

wanton thistle
#

Just being able to integrate it (so if I wanted to make a all in one charger and balancer), but also not be beholden to a supplier if it goes down or specs change. If I roll my own, I know its my own design. On top of that, it can be shared so other people can do it šŸ¤”

Also I feel that the front end where the different voltages are measured are kind of black magic for some reason šŸ˜…

delicate stream
#

Lol. Just gotta watch what parts you use, or else you might still be held back by suppliers -- altho I know Adafruit has a few good examples of dual-component designs, like PCBs that can take both the DIP or QFP versions of a chip

@crystal ore You're a contractor in California right?

crystal ore
#

Yep. I have a single-member LLC for my business.

lusty fossil
#

ok cool. I'm going into negotiations to convert my job to a contractor position (not what I wanted but I'm not 100% in the position to go job shopping right now). Do you have any tips for a newbie? Do I need an LLC? I have nearly sold three projects that will keep me busy until the end of July but I don't know how to go about negotiating as a 1099 employee.

crystal ore
#

So that's somewhat troublesome in California. A recent law clamped down on using contractors as employees, and converting a current employee would likely be a red flag. I had to wait 2 years to consult with a former employer. So you might need to check with the company's legal folks.

#

An LLC isn't needed, but sometimes can be a factor in how independent a judge would think you are.

IDK I'm just of the opinion that you should never rely on the work of a lawyer you aren't paying, unless they were appointed

delicate stream
#

Well, I don't think that thinking can hurt you XD

crystal ore
#

In this case, the risk is all on the company side, not yours. If you get reclassified as an employee later on, the company is liable for back unemployment insurance, benefits, penalties, etc. but you are just an innocent victim of the evil capitalists exploiting you. šŸ˜‰ So a company lawyer would be motivated to figure it out.

But beyond that always escapes my brain, I have big issues memorizing charts of values

You're already mostly there, although modern resistors are often 1%. I have issues like that too (hard to memorize stuff that doesn't have a specific structure). Luckily, most of the colors are in spectral order (red to violet).

It's rough for my colorblind friend

late fulcrum
#

The EIA-96 values for SMD resistors are beyond my ability to memorize. Sure, I might learn that code 81C is 68.1kΩ and 41X is 26.1Ω but it's hard to get from there to any other useful value.

#

I might remember if I used it all day every day… but I do not

#

I can’t even remember the Ethernet color code beyond using it within a day

delicate stream
late fulcrum
#

I quickly realized I don't need most resistor values, and the E12 series are the most common ones, so I learned those. I can only (kind of) remember the usual Ethernet pinouts, and that's only because I've worked with phone wiring. I still have to look up if blue/white is green/tip, or white/blue.

I wonder if they discussed colorblind folks when deciding on the rings method

delicate stream
#

Probably not, the ring method is old as dirt

late fulcrum
#

The majority of the resistors I use are 330Ω (orange-orange-brown, for LED current limiting), 1kΩ (brown-black-red, for decoupling logic circuits), and 10kΩ (brown-black-orange, for pull-ups/pull-downs). Those are pretty easy to tell apart. I bin my resistors by the third (decade) band, so for those three, they're each in a different bin: brown band for LED resistors, red band for decoupling, orange band for pull-up/pull-down.

delicate stream
#

I don't currently have bins... I have a bag with the bandoleer things with the values written on them, in order from lowest to highest

late fulcrum
#

In the old days, the assumption was that color-blind people would a) use resistors in marked envelopes, b) use a multimeter, c) work with someone with color vision, or d) find a different job. Those days weren't the "good old days" in many important ways.

The "good" old days were pretty heavily biased in favor of neurotypical folks

Neurodivergent folks in those days tended to find jobs that suited their abilities. Some became lighthouse keepers, others mathematicians, others teachers, and so forth. However, many were just shunted to the edges of society and their special gifts ignored/shunned.

Oliver Sacks' story about the surgeon with Tourette's syndrome is a fascinating example.

The situation basically flipped over the last 25 years. Now neurodivergence is sought after and abused

late fulcrum
#

Neurotypical people still are abused as well, as they always have been, just differently.

The problem is lots of neurodivergent people don’t realize it’s abuse by their employers because they just want to solve the problem. And then they get burnt out and left for the wolves of poor performance reviews.

I love working hard on interesting problems but hate even looking at boring ones.

#

Knowing about HSP has helped me better cope with my life, but I don’t like the flagrantly throw around labels

late fulcrum

On the one hand, I'm curious, on the other hand, it might point up some things that would let me better accommodate my peculiarities, on the gripping hand, I'll probably never get around to scheduling specialists, tests, etc. to arrive at a real conclusion.

I get all the benefits of quickly learning and absorbing new information but don’t get stuck on particular topics like can be common with those with autism or ADD/ADHD

delicate stream
#

If you don't feel you're suffering with your current situation, it probably isn't something you should investigate urgently... I suffered before my ADHD diagnosis and subsequent therapy/treatment to learn how to deal with it

tardy badger
#

It also means I have better coping abilities for getting overwhelmed by stimuli

#

But there are not so fun things about it

late fulcrum
#

The last time I was seeing a professional (in my late teens), they explained that I was certainly abnormal in a variety of ways, but that I was well-adapted to my particular way of life. Eh, I'll take it.

tardy badger
#

Like not being able to control emotional responses when people are presenting very dominant emotions

tardy badger
#

HSPs suffer from emotional hijacking where they end up mirroring and sometimes amplifying strong emotions of others

late fulcrum
#

I learned to deal with that particular situation an odd way: by theatre. So when my emotions threaten to take me in a bad direction, I can switch into "play acting" mode and present whatever effect I need at the time: confidence, bravado, obsequiousness, etc. It's almost like magic.

tardy badger

My parents met on the debating team, and were relentlessly logical. The only way to make any headway in our house was to be logical and play by the rules. If you attempted a fallacy, they'd call you on it. If you got emotional, they'd call you on it. When I got older, I ended up in relationships with some manipulative people, and I frustrated them to no end, because I did not react like they wanted me to. I'd come right out and say "thank you for the offer of the lovely guilt trip, but I'm not interested in taking that trip."

The issue is, you’re going to have a very hard time finding a therapy person who knows about HSP and knows how to effectively treat it

I had a psych professor who was very much a behaviorist, and I am ... very much not a behaviorist, so we spent a lot of class sessions arguing over things. One of the takeaways I got was that, while it is a "soft" science, it is indeed a science, but you really have to know your stuff, and a lot of the practitioners are ignorant of the actual details of what they claim to be doing. Sort of like real doctors vs chiroquacktors.

delicate stream
#

What’s a behavioralist again?

late fulcrum
#

That's the hard part: while many people (including myself) have benefited from correct treatment, many people (including myself) have suffered from incorrect treatment. Finding the right practitioner and modality is hard, and doubly so when you're in need of mental health support.

There's currently not a mechanism to match people with practitioners. And a bad match can be worse than no treatment at all. At the current state of the art, you really need to find the right practitioner.

tardy badger

Other countries tend to do better to in how they incentivize practitioners to deliver care. And by incentivize, I mean set very enforceable rules about patient care.

#

If your exposure of mental health care is the US, yeah.. it’s a really big mess here

I’ve had apprehension about finding a therapy provider simply because I haven’t found one that understands the specific things I’m dealing with.

In statistics, is the bell curve divided by sqrt(pi) to force the area under it to be 1?

Because I was having a conversation with a statistics student about the bell curve, and I told them the area under it is sqrt(pi) and I can prove it, and they seemed very confused, like "No, it's 1"

tardy badger
#

Bell curves represent a standard or Gaussian distribution, that’s about as much as I remember of it 🤣

#

The total area is 1 though since it must represent 100%

hasty quarry
#

Yeah, that's what I supposed. If that's the case, vertically compressing the curve in a convenient way would still preserve its shape, so it would make total sense to do so

tardy badger
hasty quarry
#

But that's not true for the function itself, e^(-x^2)

#

It is though, for e^(-x^2) / sqrt(pi)

tardy badger
#

Sure, but if your thinking in statistical analysis, it’s 1. Since it’s a distribution of a whole.

hasty quarry

I'm thinking about what function's graph statistical analysis uses in practice

I understand why it must be 1 to represent 100%

From a purely mathematical standpoint, you’re right. Statistics unfortunately is really convoluted math..

Let me go look at see if I wrote anything specific in my stochastic analysis notes from my undergrad

Well, it originally was supposed to be $125. but so many people didn’t want the credit monitoring (and why would you, Equifax let them take your data in the first place) and a majority of people opted for money

So most people are getting less than $10

# hasty quarry In statistics, is the bell curve divided by sqrt(pi) to force the area under it ...

I think before one can meaningfully answer this question, you need to know that:

  • the normal distribution is not made up, it actually occurs in the wild
  • in a sense, the "real thing" is the distribution itself; the bell curve is just a certain kind of description of the distribution -- namely, it is a probability density function (pdf).
    I think if you unpack the relationship between the pdf and the probabilities associated with drawing from the described distribution (which is pretty subtle btw and involves calculus, and more generally, measure theory), this question might resolve itself. You won't get an explanation of why the normal distribution shows up in so many applications of interest, but you'll see that the requirement that the pdf integrate to 1 is a consequence of the fact that a pdf is a description of a probability distribution.
hasty quarry
#

Well, the thing is I was aware the distribution's behavior follows the shape of e^(-x^2)

#

But then I later found the area must be 1 for it to be statistically usable

wooden schooner
#

what do you mean by that?

#

do you have a precise version of the statement "the ditribution's behavior follows the shape of ..."?

I mean the graph used in statistics is not e^(-x^2), but e^(-x^2)/sqrt(pi)

I feel like a community can become toxic and self select for the kind of people who are giving free "help" not because they like helping other, but because they like to feel superior and rub noses in it. Just an observation after being on the internet for a few decades.

Yeah, agreed

I’ve met some great professionals in my time, but definitely had very sour tastes left by people I was supposed to learn from

what can i do to connect battery without solder

#

pogo pins?

fierce prawn
#

@delicate stream

dusty citrus
#

I'm unsure what you're asking...
with that board I doubt that you can be off of solder, unless you find some sort of tiny crimps
if you're asking for battery connectors then there's plenty of choices, just googling out battery connector should give you choices
if you want to avoid like a spot welder there are solderless cases that allows you to do that, I can't remember the naming right now though

fierce prawn
thick wind
#

Those pad were intended for use with soldering, preferably a surface mount connector of some kind. Adafruit’s lipo bff connects a battery to the qtpy/xiao over vusb but even then I would assume some solder is required for the headers…

#

You could potentially press pogo pins onto those pads, but that would require a custom board with some sort of mounting solution…

#

Considering the price point of the Xiao, not exactly a viable product for its market…

solar kindle
#

Pogo pins or similar press-fit connectors would probably do. If it's just a temporary thing for testing, then J-clip jumpers would probably be OK.

tardy badger

Pretty darn close to what this will end up looking like šŸ¤“

Just need a slight modification to the slots for the Apple Watch bands and to make a wee bit extra room at the bottom for the battery

blissful roost

It certainly warrants testing, but not at the cost of giving money to these a-holes.

tardy badger

Most phones put the antenna on the side bumper

To actually improve the signal, they’d have to improve the antenna, tuning network, etc..

It’s not as simple as a metalized sticker like it is with RFID/NFC

Lol

whole jacinth
#

if a working version of such a device did exist, it would almost certainly have to be different for every model of phone

tardy badger
#

Yeah, this is especially true because the same Wi-Fi IC implemented on different boards for instance has to have different matching/tuning networks because the entirety of the design affects antenna performance

#

Top two paragraphs

whole jacinth
#

wireless device manufacturers have incentives to cram the best possible RF performance into the available volume, so it’s highly unlikely that a cheap sticker will improve on it (quite possibly the opposite)

Are you trying to insult my potion brewing skills?!1!

tardy badger

The issue tends to come down to the lack of critical thinkings. The US education system has a problem where we prepare students for two things:

  1. College entrance
  2. Workforce entrance

But both require critical thinking skills. You can get into both without, but it’s hard to be adaptive and have a deep understanding without it.

#

We have a lot of push towards ā€œaccept this because I say it’s trueā€ and not so much ā€œI’m saying this is true, but you should conduct your own experiment and verify.ā€

Part of why I love this community is that there’s a strong emphasis on safe experimentation.

There’s tons of tribal and well documented knowledge here too, and it’s used as a means to encourage people to try it for themselves. That’s a really amazing thing.

For RGBW I’d do a parallel pack

wanton thistle
#

ahh I have 4 in series šŸ˜… and they are high efficiency types, so the Blue/white isnt your typical 3.6V, its 2.95V

#

Parallel pack might make sense. Dont need high discharge, so I can get 3000mAh batteries. Choices, choices...

tardy badger
#

I say parallel because of having a higher current draw than a series back

#

Essentially Kirchoff’s laws give us hints as to what’s a better setup.

I’d rather have a lower voltage and higher current capacity than higher voltage and be limited by the maximum discharge rate of the weakest cell in the pack.

wanton thistle
#

Easier to charge and design a charger around as well. Dont gotta worry about pesky balancing.

#

The cells balance themselves out in parallel

I forgot: The trade off is finding a boost converter that can handle at least 700mA constant draw. For that Im looking at an ext switch

Ive found some, but thats the trade off: not being able to find something quick and simple.
