... it is like the energy is equal to the heat +(it is a minus) work. both of them are in joules, in the case it doesn't receive or give heat(supposing an ideal situation), the physical work will decide if the gas will increase it's temperature or decrease it's temperature, if it diminute the pressure and increase the volume it will be colder the oposite will make it hotter, that equation that I posted is not useful at this situation because you have PV at the same side(one increases and the other decreases) and it doesn't give the energy in joules... the equation used is U = q - t ... U is de difference of energy, basically it is related with the temperature. When you make the gas pass through a bigger place it decrease the temperature, when it pass in a small place it makes the gas hotter, this is what the refrigerator does. You are applying work and taking out work with the walls of the gas. When you use the deodorant, what is happening is even that it is going in a small place, instantly after this it go to a way bigger place ( your room) and it decreases the temperature following First Law of Thermodynamics. Science.

[late fulcrum]

You can even build a refrigerator using a rubber band.

[jovial path]

How does your project look now?

[honest jolt]

Same lol, just that every LED works right now

[jovial path]

Nice ✅

Me and my father bought the material to do a project with cube LED's

Did you buy the PCB already made

With all the material? Microcontrollers, etc...

Or you're designing and programming everything?

[jovial path]

Did you buy a kit for it?

I think the engineers that makes the libraries for the code of these kind of projects are so hardworkers... I really admire them.

[honest jolt]

(sorry for not responding I was coding something else XD)
I actually just bought a box of 1000 LEDs (200 for red, yellow, green, blue, and white) and so I just used blue. Then I plan on using a "double sided PCB kit" board (which is a perf board but green and the holes are pre-tinned so soldering is much easier to it) and then I haven't decided on the microcontroller but I'm probably gonna use my Arduino Mega clone after it decides to unbrick itself and actually show up as a serial port. 😦

(so basically "from scratch")

[jovial path]

And the libraries?

What library will you use?

What ci will you use to handle the LED matrix?

Is there a MAX... For it?

[honest jolt]

I didn't think that far ahead yet 🙃
Would like some suggestions 😅
I also may or may not be afraid to ruin it after spending hours on it fixing it so that's why I may or may not be procrastinating 😂

[jovial path]

The one I have here I think everything is pre-made includive the code. I think.

[honest jolt]

(Also before doing it I would highly suggest buying a bunch of solder and make sure your soldering iron is in good condition. Saying I used a meter length of solder on it would not be an exaggeration.)

[jovial path]

You just have to make the cube, solder the components in the PCB and put the pre existing code.

[jovial path]

We have a lot or solder here. ✅ 👍

[honest jolt]

Do you have a link to the kit? I would like to see how they designed it compared to my homemade version :p

[jovial path]

Here is an electronics house.

[honest jolt]

Unfortunately my family really dislikes the smell of soldering 😦

[jovial path]

Tomorrow I give you, my father is the one with the links.

[honest jolt]

And I'm more of a software guy then a hardware guy so I constantly keep screwing up which makes it take extra long lol.

[jovial path]

Think your matrix has so many pins... You need a special ci to handle this.

And make it easier to the microcontroller to work.

With less pins.

It uses SPI to do it I think.

It makes a conversion.

Is like a code/ci to handle a lot of pins with just a few pins.

[honest jolt]

I was thinking of using something more powerful like an ESP32 and using a bunch of shift registers but I'm trying to not buy anything for this project so I guess I'm just gonna end up using the mega lol

[jovial path]

Shift registers.... These are memories for me.

[honest jolt]

lol

[jovial path]

But they are, they store bits.

Paralell/Serial

Serial/serial

...

My father made a project in the past using shift registers.

It made cool patterns.

But I really so not know how the code looked like.

But it was 10 LEDs.

A shift register and an Arduino.

[delicate stream]

Super generic

[honest jolt]

ye

i think imma stay with windows 10 cause i'm too lazy to transfer all my data and reinstall all my programs

cause my processor only gen 3 i7 so idk if i even can upgrade

[delicate stream]

Well, if your system is decided to be allowed to run 11, it'll just be an update, you don't need to reinstall

[honest jolt]

unless windows 11 installer will keep ALL my files intact across upgrade but now i'm just wishing

[delicate stream]

It's basically just Windows 10 with a new skin... installs just like all the previous major 10 versions

[honest jolt]

(as you can tell i didn't study up on windows 11 😂)

[delicate stream]

lol

[honest jolt]

(didn't really like the look so wasn't considering on upgrading)

[jovial path]

I used Windows 11 today.

I liked.

[honest jolt]

[jovial path]

There is a graphing calculator.

[delicate stream]

I dun like it, but I think I can live with it... but not moving for at least a year

[honest jolt]

in windows 11 calculator app??? 👀

[delicate stream]

I always run a year off for feature updates

[jovial path]

No

It is in the OS.

[honest jolt]

*like in the built-in calculator app?

[jovial path]

Yes.

[honest jolt]

noice

[delicate stream]

10 already had graphing, lol

[jovial path]

They should include more functions.

I tried to find integral, and there was not integrals.

Another problem is when I copied my equation to WolframAlpha

[honest jolt]

so that windows updater doesn't delete your files like last time *cough* *cough*

[jovial path]

It came with strange characthers.

So I had to erease them manually.

[delicate stream]

Actually it's the same app version for 11 [left] and 10 [right]

[jovial path]

I think it is too early for windows 11.

They should have waited until 2026

Or 2025...

[delicate stream]

I think they should just have dropped the 10 and it should just be Windows

Especially since this is apparently version number 10.somethingsomething....

But I mean, 10 is about a decade old, not like they just released it

[jovial path]

Time difference between Windows XP to Windows 7 is more than 9 years

I think

[delicate stream]

6

[jovial path]

No it released in 2015

[delicate stream]

XP was 2003, 7 was 2009

[jovial path]

Really?

[delicate stream]

Wait, yeah, 10 will be 10 years old when support ends in 2025

Oop, no, XP was 2001

[jovial path]

Time pass so fast...

[honest jolt]

wait what when did this happen lol

[delicate stream]

But 11 is basically just 10 with tweaks

[honest jolt]

(yea windows 11 was too early imho)

[delicate stream]

I dunno, I don't use calc for more than simple stuff, lol

They could have just released it as another big 10 update, the name means nothing

[honest jolt]

i also don't like the new icon 😦

actually i don't like the new look at all i just want the better monitor support and any other improvements that don't change the gui

[delicate stream]

I hate all the icons

Yeah, I hate all the new GUI

[jovial path]

I liked, it feels good.

Remembers water...

[honest jolt]

your opinion is wrong 😂

[jovial path]

Or something like this.

[honest jolt]

(as long as you like it that's good)

[jovial path]

The blue...

[delicate stream]

As you can see... still Windows version 10.0

[honest jolt]

but the new wallpapers are much better then the built-in ones for windows 10 ngl

[delicate stream]

Ehh

I like the Windows logo desktop, I often use a variant of it on non-themed builds and VMs

Like this one

TIL I can take a screenshot from within a VM/Remote Desktop session and paste it on the host machine, lol

And I finally found the right wallpaper for this system XD

[jovial path]

I think Hockey is such a violent sport :(

I think it is cool, but it is too much contact.

When the player hits other it looks like is intentionally to make the other fall in the rigid ice!

I like how the game goes, it looks like football but it is violent. I think it should have more strict rules for safety and safer clothes.

[ancient kindle]

it is intentional

[umbral phoenix]

football is pretty violent too as evidenced by the brain injuries among other things

[jovial path]

In football this is not allowed.

[ancient kindle]

they already have EXTREMELY strong regulations

[jovial path]

I mean football

With the foot.

Kicking the balls. Like FIFA.

[late fulcrum]

Yeah, not handegg like they play in the United States.

[ancient kindle]

in football it's full of faking injuries instead of getting real ones

[jovial path]

In hockey?

[ancient kindle]

yep

[jovial path]

I watched and I saw strong contact.

And it was not a fault.

[ancient kindle]

yup

[jovial path]

What is handegg?

And when they go agains these transparent walls!

It must hurt!

[ancient kindle]

remember they're heavily padded, have done it a million times, and are absolutely pumped with Adrenalin

[jovial path]

They must have better protections

In their sholders.

In that region.

[ancient kindle]

they do have heavy padding there

[jovial path]

Soccer is not meant to hurt at all.

Or to have contact at all.

[ancient kindle]

the same could be said about hockey

it's not the intention but it happens

remember also that in hockey they have large knives on their feet, and you never see them get used as weapons

that's a huge part of the regulations

[jovial path]

It will not happen.

Ever...

[ancient kindle]

it has happened

[jovial path]

No....

Not intentionally.

Accident.

[ancient kindle]

without regulations it could definitely happen

[jovial path]

Very bad.

[jovial path]

This is the worst thing I see in Soccer.

[ancient kindle]

just like in football if there were no regulations against contact players would be tackling each other left and right. boom, american football

[jovial path]

Nothing really physical.

And just a few selected players do this often.

Like Neymar or Cristiano Ronaldo...

I did not see Ronaldinho Gaucho doing this, Ronaldo, Zidane falling for no reason.

[jovial path]

It feels so weird, everyone is looking at them at TV and they do it anyway!

It is like they do not care about doing the right thing.

Fair play.

With brazillians clubs I do see some players falling for no reason but it is not everytime!

And sometimes I make mistakes in my judgements...

[jovial path]

... It is like comparing liars(soccer) and violents(hockey)...

None of these sides are ok.

I only have RPN calculators, and have used little else since early undergrad. They're quite efficient.

[jovial path]

We will buy a HP-35s used (RPN). I love this calculator because it has a similar name to the HP-35 the first scientific calculator. The HP-35 and the HP-35s looks quite the same. I like it.

RPN seems interesting but I don’t really want to relearn math you know

[jovial path]

tomorrow is my driver licensing exam.

I'll take one of these with me:

It will be very weird to take a clock like this with me to a test. They do not allow digital clocks ( I only have digital wristwatch, not analogic ones). I tought in going to the shopping to buy one, but I would loose too much study time for the drive licensing exam. I didn't buy before because I asked to my teacher if they had a clock in the test room, and he said: no, it made me completely surprised because that would be very strange, I was asking just to confirm the obvious, and they do not have a clock in the room. But my exam will be in a computer, so I hope it will have a clock in the software.

[ancient kindle]

if I were you I wouldn't worry too hard

usually in those tests they are super easy and give you loads of time

Guys, question for bachelors, any tips for facing the final thesis defense or whatever it is you call the final test for your final bachelor's project?

[jovial path]

Use the office hours as much as you can.

Write a lot of PDF's with 25 questions each and go to your professor's to talk to him.

To not become a weird situation do not ask more than 25 questions per day.

[drowsy zephyr]

we're talking about a bachelor's degree final project right?

[jovial path]

Yes, I think.

Professors have experience with this.

More than anyone who is not a professor here.

They are the perfect ones answering questions about this.

[tardy badger]

Usually involves a large written paper on the project, my team turned in a 50 page document and made a poster presentation

Some schools have expos once a year in the spring to show case senior projects

[drowsy zephyr]

what about the final presentation where you present your work in front of lecturers?

any tips?

and what are the precentage of you failing?

[tardy badger]

As long as you put in the work and document the process how they want you to, and then do your best presenting you should pass

[drowsy zephyr]

some people told me that if your mentor has already accept you going forward with your work, you can trust in the quality of your work

[ancient kindle]

unless you seriously screw everything up you shouldn't fail

[tardy badger]

It’s not about being right, it’s about the process

[drowsy zephyr]

i hope so

[tardy badger]

They would love for you to have a finished prototype but it isn’t always possible

[drowsy zephyr]

would my mentor's judgement be somewhat enough to determine how am i doing?

[tardy badger]

I graduated in December with my Bachelors in Computer Engineering

[drowsy zephyr]

i've finished a protoype

[tardy badger]

Your mentors judgment will help you a lot as long as you communicate clearly

[drowsy zephyr]

but man, im too afraid because i made it based on intuition

[tardy badger]

But ultimately documentation is your friend here

[drowsy zephyr]

no concrete theory because it's just basically me freestyling on 3d design and electronics

[tardy badger]

Usually you would have had milestones to reach for your design project

[drowsy zephyr]

based on some tutorial i found on youtube, lol

[late fulcrum]

You can always work backwards from your experiements to theory

[tardy badger]

Turning in gannt charts, bill of materials, black box and white box testing

Problem and needs statements

[drowsy zephyr]

well, it's kinda too late for re writing my report, tomorrow is the deadline for me to submit my work

and my mentors have already greenlit my work

[tardy badger]

UML diagrams and whatnot

Basically they want to see that you documented the process from idea to prototype

[drowsy zephyr]

i hope my documentation is enough

what about when presenting, any tips?

[tardy badger]

Just make sure you understand your work

[drowsy zephyr]

i lowkey kinda worried if i meet a lecturer that would actively pinpoint my mistakes

[tardy badger]

Lots of visuals help and doing a demonstration

Provide any metrics or results from testing like oscilloscope readings, regression testing if there’s software

[late fulcrum]

You can expect someone to zero in on things and ask questions: however "making no mistakes" is not the goal: understanding what's going on, giving good explanations, and keeping calm is what you want.

[tardy badger]

And being honest

Most of all don’t fake your way through it

Be upfront about details you are unsure of

[terse estuary]

If you're unsure of something you might consider offering to follow up and answer that at a later point, if that's an option

[jovial path]

Professors likes honest.

[drowsy zephyr]

alright

i hope my honesty doesnt become my downfall

im just afraid i might fail

[tardy badger]

I doubt it

Just do your best, be honest, don’t fudge the results and you’ll do great

[jovial path]

You must not fight against yourself(and your own work) but you must be honest.

[drowsy zephyr]

what determines the score exactly?

let's say if i fail my project in some way or didn't get the desired results but can present why it happened and my progress, it still counts right?

[late fulcrum]

It's normally up to the judges, but in general they're looking for evidence that you understand what you're doing, and why things worked/didn't work, and you've covered the field reasonably well.

[dusk oracle]

does anyone think it's possible to hack a discord server or user to change what they receive or send?

i have had user reach out with strange stories that i did things to them

but i dont have a clue why.

people saying i sat online arguing till late in the morning.

[drowsy zephyr]

you know, working on my final project made me realized that there are tons of formally undocumented engineering feats that are documented in youtube

things that could easily be a masters degree work but it's just there

i mean, you have projects from solar trackers to prototype lightsabers

no formal papers, just youtube videos from passionate engineers

[late fulcrum]

A lot of people are doing some really amazing original research on their own.

[drowsy zephyr]

yeah

it made me wonder, should there be a change in the academia system regarding this?

[late fulcrum]

I've long thought so, but my views are skewed by bad experiences with academia

[drowsy zephyr]

i see

hmm, i wonder, any of yall have heard any experiences of someone that failed their thesis not because of their progress or results but because of poor documentation?

[tardy badger]

My advisor had a lot of pushback with how the senior design course/projects were run. It was all academic with very little incentive to do something new or out of the ordinary.

[drowsy zephyr]

heh, my advisor allows us to do anything as long as its final results are viable to be presented

[late fulcrum]

I approve of that stance, and would think if your adviser thinks it's viable, then it likely is (I'm guessing your advisor has been through this process many times before)

[drowsy zephyr]

i think so to

[tardy badger]

My advisor had issue that we weren’t really following the engineering design process so there really wasn’t any value to teaching it and not doing it the right way. My team worked on visible light communication. Essentially reverse engineering something that hadn’t been made open source yet

I really do not understand, I buy 6 very good oranges for 0.33 dollars in local farm fair and the orange and ginger tea beverage costs about 0.70 dollars... This does not makes sense. The Red Bull in the other side costs 1.5 dollars and açai is not so expensive here.

[solemn aspen]

I've heard redbull acai is good, but it's still caffeinated

Like, you're not getting that 200mg worth of caffeine from acai berry flavor that is in the can

And then I would have to recommend against energy drinks entirely

Tea is probably one of the best sources of caffeine

And redbull isnt priced at how much the ingredients cost, they are all priced the same

[jovial path]

Hum... That is true, all Red Bull flavors there in the shop had the same price. They had a lot of brazillian special flavors for RedBull.

The juice must be made from this type of peanut, it can't be eaten raw because the flavor is not good, so you toast it.

My father is 3D printing a new anti-hacker device for me. In the webcam.

...

I started reading Assassins Creed book 1 , I could read only 51% of the book(Kindle), it is horrible, the history is terrible, it is bad writen, it doesn't gives any emotion or affect to the characters... I hated. It is like random events in a random world. Bad tales...

... I was reading To Kill a Mocking Bird for the first time it is more interesting (and it is a more evolving story)

It kind of gives me a trauma... I am in 50% of the book and it is really bad the way a judger treats an inocent black person accused of a thing he did not do. I have brazillian books writen in the same time it passes To Kill a Mocking Bird, the name is "Menino do Engenho"

It has a very similar situation found in To Kill a Mocking Bird if I am not making a mistake, I read "Menino do Engenho" in the second semester of 2011.

But the judger is not a graduated judger, it is a very influencial farmland owner but he stood in the side of the innocent person that was accused of cheating, because everything told he was innocent and he was not arrested for what he did. Then there was a phrase in the book that said " the influence/leadership of the farmland owner(I forgot his name) in not based on force/violence, but in love". It kind of remembers my father, he was never used force or violence against me and it worked: I never used drugs, I never went to parties with alchool and drugs, I do not like tatoos (or similar), I was the best student (or one of the bests) in different schools, I have a lot of compliments from many professors, directors and school staff...( in all my life, specially in high school) and I help my father in the wheelchair and I will stay helping him forever, and he did not asked me for that. No force or violence from him even when he walked in the past. This must not be perfection for the whole world (or it is, I do not know) or your parents, but for sure it is for my parents :)

There is also my father and mother commandments that I wrote (it is very clear that I care about what they say) . I really do not believe someone in the history of earth has writen as many as me and I do not think I writen it too much. 😍 I am very serious about this.

I'm not sure I'm familiar with this tradition. Could you explain what it is?

[delicate stream]

So my cat tried to kill my CLUE... Got it with AdaBox015, had it set up watering a plant, strapped to a container of water... Well, he knocked the whole thing over, got it all over the CLUE and the floor. Thankfully my mom found it, CLUE was desperately trying to water the plant (pump tube had disconnected and pump was out of water anyway), so sounds like it survived... But I'll have to test it later

[jovial path]

I've writen thousands of commandments from my father and my mother in a list like. (These are not their commandments)

1 - Do not jump 3 times.
2 - Only use smartphones in an hexagonal format.
3 - Always put your clock in the table upside down...
...
There are very mature and complex commandments, there are STEM related...

[delicate stream]

... why not jump 3 times? And I've only seen one hexagonal phone... And what do you mean put your clock in the table?!

[jovial path]

It is just an example that I created 😂

4th of July. Adafruit is in USA, as well as Discord from British companies must celebrate in some way British holidays, or from France, Australia, etc... They do taught me this in kindergarten, we celebrated a lot of brazillian holidays, in a english class here we celebrated Halloween(a holiday that brazillians do not have, but USA has.).

[late fulcrum]

My kindergarten (nor middle school) didn't include much in the way of actual education.

In a french class we celebrate french holidays.

That is because you do not speak other languages.

Or they did not taught this at your school.

Yeah, kindergarten is usually like... general coordination tasks and maybe alphabet? social stuff largely

I did have a French class where we would occasionally celebrate a French holiday, but that wasn't the norm

Better to ask a lawyer.

[polar bloom]

Yes, hire a lawyer. (They will most likely tell you that what you're experiencing is not IP infringement.)

I mean, you obviously feel like someone did you wrong.

But that doesn't mean it's legally wrong.

[jovial path]

They can tell you this for free.

My brother is a Lawyer and I know more than 10 lawyers and I convived with them for years...

I saw how it works and everything.

I already participated (as a spectator) of more than one judgement

[late fulcrum]

Reputable lawyers in the US generally offer a free initial consultation.

[dusk oracle]

this isn't right. i have nothing and now the little bit i had is less

worked my butt off on nothing

[polar bloom]

So what did they actually steal from you: source code, drawings, ...?

[delicate stream]

I'm confused, what exactly was stolen?

[dusk oracle]

The idea to use a cpu as a gpu over i2c with a display attached for m5stack products

just leave it.. i give up achieving anything 😦

[polar bloom]

Unless they signed an NDA with you, an idea is just an idea. (And even if you did have an NDA, you'd need to prove that they didn't already have that idea until you gave it to them.)

[delicate stream]

Maybe they came up with it themselves? You told that person your idea a little over 2 months ago, but it probably took longer than that to develop, manufacture, and prepare that device for shipping... Shipping of samples can take weeks alone

[dusk oracle]

actually i have seen how fast they go from proto type to store

go visit their twitter page

[jovial path]

Law is good and it is a benefit to you, you should fight for it, I do not know a single person that did not fight for their rights among the people that I convived in my life.

You are deeling with a law.

That is made for right people.

So use it.

[delicate stream]

There's not much to stand on in a court case for this... You'd need proof

[dusk oracle]

i told him...

he works for m5

[jovial path]

I know people that used law with big comoanies and they won.

I know people that used law for small companies and won.

[delicate stream]

It's hard to prove he took the idea, plus you didn't have a patent or anything... and no NDA or contract

[jovial path]

That is it, most of the cases I know were against big companies.

But there was civil cases too.

[delicate stream]

I mean, yeah, individuals can win cases against big companies, but you need sufficient proof

[jovial path]

If you are right it is very likely that you will win.

If you have a smart lawyer.

[polar bloom]

If they at some point promised to compensate you for the idea or the work you put in, you might have something to go on. But there doesn't seem to be any actual IP infringement here.

[delicate stream]

Even with a great lawyer, you still need evidence

[dusk oracle]

i think i have enough evidence

[delicate stream]

You can still make your own, they can't really patent a display on an MCU

And even if they have copyright on their code, they can't sue you for your own implementation of the same concept

I mean, they can patent their exact hardware, but not the idea

And if you DID try to sue them and they came up with the idea themselves, before you said anything, they can prove they were working on it before

So you want to be CERTAIN before you try a lawyer. But if you get a free consultation, they'll tell you if you have a case

[dusk oracle]

i am so sure of it i can set myself on fire with gasoline and not blink

[delicate stream]

Uhhh.... That's... I don't know if that's a good thing?

[dusk oracle]

i need to talk to a good lawyer

but i cant afford one

so i guess i leave this.. go on with life

[delicate stream]

Look for one with free consultation. Some will only charge if you lose, otherwise the other party pays

But yeah... I think you should just make the thing

[tardy badger]

Honestly it isn’t worth pursuing

Ideas are a dime a dozen, it’s execution that matters. Continue to iterate on your product and release it

If you’re works better then the proof will be in the results.

There are tons of companies doing the same things

I mean, if Adafruit wasn’t open source and maker friendly, they could easily go after companies making similar or copy cat products

But they don’t, they just decided they would put more effort into making their products better, far better supported, and also focus on the community they build their products for.

Those are the differentiating factors on execution.

I have an example of this in my own experience.

A few years ago (like a decade ago) I came up with and started working on an idea for an app to order ahead for coffee shops where you could just pick up your order and go.

I didn’t get very far because of life and all. Another company basically did the same thing as me and they launched at a few universities including the one I was at. I was mad and wanted to sue because they “stole” my idea. I had receipts of the idea and starting to execute. It didn’t matter. There wasn’t a lawyer I could find to support my claims. It’s when I learned there are no original ideas, just execution of ideas that matters.

So moral of the story, someone did your idea? Okay just keep working on your idea and block out the noise.

[burnt tendon]

Yah, I am a bit of a broken record about this particular annoying story, but I was working at a past employer on a bang-up thing that would totally win the marketplace.

They declared that nobody would buy it, laid us all off, and I was totally OK with that because I was done with that particular employer and was already interviewing.

[jovial path]

When you have an idea before saying to everybody patent it.

always!

[burnt tendon]

You can now buy a version of this off of Google as part of their cloud offering, plus there's a hot new startup working on a artisinal version thereof, plus IBM has some products in that space....

[jovial path]

it's the rule.

this is education.

there's weird people around the world doing weird things and you must defend yourself from them.

[jovial path]

it is very cheap.

[burnt tendon]

Like, 🤷 , we're spending a lot of effort on the notion of a protection of ideas and most of the time, if a regular old inventor in their basement cooks something up and patents it, like 99% of the time, they end up getting screwed out of the profits of their investment, so pretty much all the patent system does is provide fodder for patent trolls.

[jovial path]

and it is valid internationally.

I have access to a lot of lawyers due to family, but it is as easy for me as to everybody else.

it's law and it is the same to everybody.

[burnt tendon]

And, likewise, a patent isn't about an idea. It's about an invention.

[jovial path]

I am not being specific.

[burnt tendon]

Yah, but the problem is, there's a world of difference between "Hey, someone should do a thing that does this and that" and a practical apparatus that uses items A through R to do a useful thing. The patent covers only the second.

And, likewise, the law is a perfectly reasonable abstract idea but the access to justice is very much not equal and the difference between what a person can take on under a contingency and a large corporation's ability to bury you under mountains of legal paperwork and arrange to have the suit occur in front of a judge of their choosing does not make the legal system, especially in the US, fair.

Similarly, there are plenty of countries that simply do not recognize patents from other countries or effectively do not recognize patents from other countries if you are not a local company.

It's like, my uncle invented a bunch of interesting things. I see some of them in the stores. Most of the time, he got screwed out of them, so he'd go on an invent a different version along the same lines and then he'd get screwed out of that.

So, like, if you have a cool idea and don't want someone to steal it, keep it to yourself. If you look at most of the patents in the modern patent regime, you'll discover that they are carefully constructed to separate that-which-you-can-sue-someone-for and that-which-represents-the-real-secret-sauce-of-the-idea separate anyway.

[jovial path]

I think it is very hard to defend a very good idea.

actually I think ( I think ) it is impossible.

You can't keep it only to yourself really...

and if I ask my brother or the other lawyers that I know they'll probabily tell me the same.

It is like Windows defending from piracy or anything like this in the worst case.

Why is this a common depiction of a black hole

That curving around it still looks so odd to me

Do black holes even have rings most of the time?

[crystal ore]

Well, black holes by themselves are just black. The only way you see them is if they're swallowing matter, which forms a disc as it falls in, so that's the convention.

The distortion of the shape is caused by gravitational lensing of the disc, which is why you can see its "back side" to the top and bottom. This has been fairly difficult to visualize until recently, but they put a lot of effort into getting it right for the Interstellar movie, and that's the new standard everyone compares to.

[jovial path]

I used to read about black holes in the library of my high school

there was a lot of books, it was an enciclopedia, a modern one.

There was Halking's equation but it did not have any exercice in the book so I could practice it, so I can't really say if I learnt it or not.

[jovial path]

"I used to read" = 3-5 pages of a book with a very large area. I did not see a similar photo in the enciclopedia.

page = a front of a page, not a whole page, two sides.

[jovial path]

The photo in the enciclopedia was something like this.

extremely similar, if not the exact same photo. Bending light with it's gravity.

Only two things bothers me a lot in this photo... why there are no stars in front of the black hole, between us and the black hole and why there's no light pollution in it's area.

[wary herald]

That's cool...

[crystal ore]

That's just a simulated view rather than a photo. There's no particular reason why there shouldn't be foreground stars too.

[wary herald]

Black holes are really cool

[jovial path]

That is true.

... I passed trought a very bad situation now... I was helping a high school student from Canada on discord (using microphone) and I kind of spent some time with him explaining mechanical physics... and he asked me can you help me on 7th of July 13pm-15pm (a few times). It really felt like he wanted help to solve his test from school and when I said I couldn't he didn't want help anymore.There's wrong people all over the world...

It was so nice to help him with questions... but he made me feel really bad in the end.

[real falcon]

sigh people trying for shortcuts

people dont realize that merely means person dont know stuff

[jovial path]

If he spent 3h with me he would understand everything. I could literally do this now. It is friday and I can start to study 9am tomorrow, no problem

There are concepts that if he learn now in mechanical physics it could help him solve problems for physics 2 and 3, like dealing with units, manipulating the cartesian plane,thinking about particles it would be easier for him.

because they are completely related.

and I didn't give him!

because it was so hard to me to understand everything, studying the whole day while he was surfing or something like this.

I explained exactly this.

and I did not give him the answers

I told him this after the test.

There was a movie that I watched in the past Les Choristes (it is a french movie), that kid from high school made me remember a very bad kid in the movie really (the high school kid from Canada), that did a bunch of wrong things...

I told the middle school kid that years ago in this green area.

This is how my father told me to register my ideas ,projects and circuit designs.

It is called "Instituto Nacional da Propriedade Intelectual".

[jovial path]

In your country there must be something like this.

there are multiple actions you can do about your patent, like if someone is copying your idea, you just choose the option for them to analyse and they will protect your idea/project, them it must start the fight.

It must be exactly the same in your country because it is an international law.

[delicate stream]

Patents are issued for specific designs tho, not a general concept

[solemn aspen]

didnt know microcenter sold the gmmk kits

[delicate stream]

Plus I don't think you can get the patent (or retain it if you do) if someone else proves prior art

i had no idea glorious was selling a full size kit

oh they are

i have not been following them for a while

[delicate stream]

Yup! They have prebuilts too

But I like putting the switches in :D

[solemn aspen]

i saw the prebuilts

you gonna at least lube and film the switches

?

[delicate stream]

Oh wow, these are softer and quieter than the whites

Lube and film?

[solemn aspen]

yeah

lube the switches

and film them

like put the films in them

[delicate stream]

This is a new concept to me XD

What film?

[solemn aspen]

oh, youre not into keyboard building i take it?

[delicate stream]

Not really, this is my first real foray

[solemn aspen]

so lubing, you take each switch apart and brush on certain key switch lube and there are gasket like films you put in between the housings

its a process

[delicate stream]

Ahh... I assume the lube gives you smoother travel? What does the film do?

[solemn aspen]

it dampens and deepens the sound

also reduces keycap wobble

both lube and films make your switches sound so much better

[delicate stream]

Hmmmm.... Well, I like the clickity-clackity, so I probably wouldn't lube

[solemn aspen]

but youre using blues so it wont do anything

[delicate stream]

Probs gonna skip XD

[solemn aspen]

the click is caused by a jacket i believe so it would be impossible to remove that sound

[delicate stream]

It's amazing how different the Gateron blues sound compared to.... whatever is in the Redragon I'm typing on

Oh, they say Redragon on them

Low profile MX compatible

[solemn aspen]

i think red dragon uses oteamus or however you spell it

some cheap chinese garbage

[delicate stream]

Guess they're rebranded from whoever they use

[solemn aspen]

and most people prefer gats over cherries although they are the same design

just manufactured differently

[delicate stream]

I do like the Gateron sound over whatever the Redragon is -- the Redragon has a metallic reverb/vibration to it, the Gaterons don't

[solemn aspen]

yep, the red dragon switch uses a super cheap click jacket that goes down then up

and since its suspended by a spring, there is reverb and ring

[delicate stream]

Kailh whites have a louder click, but it feels like it's the same actuation force? Or at least close?

[solemn aspen]

here is a cheap film i put on my gat browns a while back

i think the kailh whites are definitely heavier and they use a click bar

[delicate stream]

Ah

[solemn aspen]

so its actuation point feels different too

[delicate stream]

I can't really feel a difference, but it's also almost midnight XD

I like both tho, sound good, feel good

Need to get some sleep... night night

[solemn aspen]

i may be wrong about the whites click process

the gateron ink blacks are top tier sounding switch though, especially when filmed and lubed

check it out sometime

[delicate stream]

I'mma design my own switch that's rainbow, and when you click it, it sounds like a thousand keys clicking at once

[delicate stream]

Keeboar! :D

Ohhh, the caps come in the order you'd install them... Very nice

It should be more people here working on Google Maps in my city ( I know there are volunteers that do this...). I use Uber often and sometimes it shows the wrong tragectory. Does it happen in your country too? Actually before the ride begin they should allow the user to decide the tragectory. When this happen I tell the Uber driver to go in a better tragectory.

[ancient kindle]

"wrong" meaning not an optimal path?

map programs no longer are just trying to find the smallest distance along the roads from A to B

they are now a way to influence traffic patterns to make it overall faster for everyone

if they can tell some people to divert to another road, they can reduce the traffic flow on the fastest road and prevent a traffic jam, for example

so it may be 1 minute out of the way for you, but that might make everyone else's commute 1 minute faster

[sick adder]

Hmmm the commodore 64 keyboard was an 8x8 matrix plus two special keys (Restore and Caps Lock) that were outside the matrix; so it used 8+8+2=18 pins altogether. An inconvenient 6x11 matrix could have done it in 17. Just contemplating making a keyboard that matches the layout but for use on a modern PC directly. A foolish project, I would never use it much.

[crystal ore]

I think the RESTORE key was directly connected to a non-maskable interrupt input, so they wouldn't have wanted it in the matrix anyway.

Didn't realize that Caps Lock was special, though... interesting quirk.

errr and I think it was shift-lock, not caps-lock. easier to implement.

I'm a little surprised shift-lock didn't just close the same switch as left-shift, or that the left and right shifts were ganged together. but they must not have needed to save another I/O.

huh I wonder what's good about "semi-box". full box are said to prevent debris ingress when the switch is pressed. https://www.banggood.com/10-or-70-or-110-Pcs-TTC-Gold-Pink-Switches-3PinLinear-Mechanical-Keyboard-Switch-for-DIY-CHERRY-MX-Mechanical-Gaming-Keyboards-p-1831092.html?cur_warehouse=CN&ID=511073&rmmds=buy

They can rotate like 30 degrees

So all of the keycaps are at different angles

[sick adder]

Yeah I saw something similar with my design. It's surprising how far the keyswitch can twist. If I assemble the 2nd one I'll do it with a 3D printed plate, which will restrict the key rotation. I have a feeling a soldering jig could do the same thing, if you didn't want to add a plate @ancient kindle

the "7" on the left I think is the worst and that's after tried correcting it; the right is fitted BUT NOT SOLDERED with the keys snapped into a 3d printed plate.

[ancient kindle]

A more restrictive footprint might work too

like very small holes for the legs

[sick adder]

I think this is also why there are the "fixation pins" on some cherry compatible keyswitches.

[ancient kindle]

Yeah

[sick adder]

fwiw I used kicad's standard footprint and yeah it's pretty loose

vs what I think are kailh switches

[ancient kindle]

A case would probably help here too

Keep them all aligned

[sick adder]

that may be what I mean when I say "plate". The piece that the keys can all be snapped into before soldering.

though the macropad also uses the sockets and those don't allow the keyswitch to rotate as much

[jovial path]

How important is it to the keyswitch to rotate?

[sick adder]

It's undesirable

solutions like plates & fixation pins are all about reducing/eliminating it

[jovial path]

These fixation pins? Yes. I think it is.

the larger one seems to be present on all cherry mx style keys, but the two smaller ones are not.

when they go into a matching PCB non-plated hole, it will greatly reduce the ability to rotate, compared to the metal pins alone.

[jovial path]

I did not understand the mathematics. It has 64 keys (8x8), then why 8+8+2?

[sick adder]

8+8 for the matrix, 2 for 2 special keys

[ancient kindle]

Matrixes only need 1 connection per “row” and “column”

[jovial path]

Where is the special pins?

[ancient kindle]

That’s only the keyboard

Doesn’t include the special keys

[sick adder]

an example without the extra 2 plastic posts/pins https://cdn.shopify.com/s/files/1/1874/9417/products/Cherry_MX_Switch_Bottom_grande.jpg?v=1541502175

[ancient kindle]

That that’s what cherry does

They don’t give us the fancy helper posts

Luckily these pcbs have the little holes for those things, so I guess I’m gonna go buy some new switches

'night all!

[jovial path]

Good night. Nice New York has one hour difference to Sergipe ✅

[ancient kindle]

The fireworks out here are insane

And the police are actually pursuing illegal ones

[jovial path]

This is very bad!

It very interesting how fireworks work. Each one has a different chemical element that burns with a different color. My chemistry book had a very small list of some chemical components used and it's colors. The different colors are due to Bohr's chemical model of elements. It is like different molecules has different levels of energy to the electrons jump one to another and depending on this jump they emit a different frequency of light. The packages of energy received (it is like a button, you can give it different forces, but until you reach the right force you can't press it) are discret so are the emission of energy in the jump.

[terse estuary]

Same general phenomenon that causes different semiconductors to make different colors in LEDs if i remember correctly

[hasty quarry]

I just got burned by fireworks...

They were exploding above where we were sitting, and I felt a prickly feeling on my skin

I just got burned everywhere by micro shrapnel

Did not even know this could happen

I smell of gunpowder

[terse estuary]

Unfortunately what goes up must come down. Were you able to rinse your arm off some?

[hasty quarry]

This seems to be chemical

My skin is literally just brown spotted now

Hahaha

[terse estuary]

That's no good. Hopefully it resolves itself though

[jovial path]

Yes, different semiconductors has different tesions to allow the electron to pass, this is the discrete energy to make it go out of it's orbits.

V = J/Q , I think I just answered an old question that I had here, the Joules in V are the Joules in the orbitals of the atoms... Got it ✅ 🥳 .

[hasty quarry]

Yeah it’s fine. Skin is always renewing

[hasty quarry]

Don’t you mean J/C

Joules per Coulomb

[ancient kindle]

It’s joules over charge

And charge is in coulombs

[jovial path]

What is wrong really is using J in the numerator.

F = kg*a

Like this.

Happy 4th of July!

[tardy badger]

Yeah, people were shooting fireworks all around where I live in Utah. Yay for people not caring that they could spark fires that could burn the whole town down since things are so dry

[jovial path]

When people use fireworks here they are very small. Always. A long time ago a little fire of them felt in my body but I did not feel anything.

[jovial path]

4th of July! 🥳 🥳 🥳 🥳 ✅

[tardy badger]

I was just reading an interesting article about LIGO and VIRGO detecting two collisions between a neutron star and a black hole. It got me thinking about how a planet might orbit a binary star system.

https://astronomy.com/magazine/ask-astro/2020/01/can-solar-systems-exist-in-a-binary-star-system

The reason I got thinking about this is because they posited that for a neutron star and a black hole to collide, they would need to start as a super massive binary star system

[jovial path]

Can I design a project like this and order like I order a PCBA?

[tardy badger]

For an HVAC condenser unit?

[jovial path]

For any electrical project.

Transformers, air conditioners...

[tardy badger]

Apparently they found a planet orbiting in a trinary star system. https://manyworlds.space/2016/07/07/three-star-ballet-with-exoplanet/

[tardy badger]

You can make your own transformers

You can make high voltage supplies too. But the caveat is it is very dangerous

[jovial path]

I know, a friend taught me recently and I took couses on university teaching me this experimentaly.

[tardy badger]

The reality is if you have the knowledge you can do it

[jovial path]

But I want it to be pretty.

And to look real and professional.

And huge.

[tardy badger]

It’s usually a matter of if you should.

The history of hot water tanks is a good example of how much effort has gone into taking something mundane and making it work very well. But the caveats of the history of them is how dangerous the process was and how many ordinary people died before they became mostly safe

[jovial path]

I want to order like I order PCBA, there are companies that do this?

[tardy badger]

Contract manufacturers usually offer varying levels of product support

Some will even do standards and conformity testing for national certification processes

But you can do a lot with a 3D printer

[jovial path]

Ok. How can I use a 3D printer to make a transformer.

A plastic transformer?!

I want them to put all the components in the electrical project, like PCBA, in the case of an air condictioner: the cooler, the motor... Etc

But, my project, everything in the place that I want and all the parts that I want, just like PCBA.

[tardy badger]

https://youtu.be/9BeTMMI8wRc

For the enclosure of an AC unit you’d need some place that makes sheet metal enclosures

You would send that enclosure to a contract manufacturer

The contract manufacturer would probably assemble your PCB and then end product

But that’s usually very expensive

[jovial path]

They only make a lot of units? They accept creating just one?

[tardy badger]

For instance plenty of contract manufacturers in the US cost $100/hr + the cost of the components and other materials

A project like making an AC unit could easily cost $2500+ in man hours alone

It’s not impossible, it’s just really expensive

You should only ever consider a contract manufacturer to make a complete product when you plan to sell a commercial product

Using one for PCBA is fine

But typically there is minimum quantity and some parts they likely won’t have that you would have to add yourself

Most people just learn how to do most of it themselves and source as much fully assembled components as they can.

3D printers, basic wood working and metal working tools, a soldering iron or hot air reflow station

[jovial path]

How do I find companies to buy my electrical products, like transformers from these contract manufacturers?

(Is it better to ask to my professors?)

[tardy badger]

Basically you just have to market your products. Sometimes it’s just finding the first person to buy it. If that’s what you’re asking

[jovial path]

How do I find the first person(company) to buy it?

[tardy badger]

You talk to people

Talk about it all the time

Eventually someone will be interested enough to buy it

And sometimes you’ll find people who will share their experience with your product

[jovial path]

Aaggrhh... I do not want to worry about sales. I want to worry about engineering... math!

[jovial path]

This looks better.

Nice twitter.

There are only posts related to engineering. You must be very commited.

[jovial path]

Oh.. I got it now, it is not your twitter.

[tardy badger]

It’s a customer’s Twitter, someone who bought a board my company made

All you have to do is find someone who will be your first buyer. It varies by what you make

Making stuff to sell is the easy part that ultimately everyone wants to do, which is great because people should make things. The hard part is selling it. Some things just sell with little effort at all, it’s rare that this happens. Most products never are successful. Most fall time obscurity because they didn’t do enough, did too much, there just wasn’t a need, or a variety of other factors. Sometimes poor planning, lack of reinvestment, etc…

Engineering is fun and important, but learning how to sell is just as important as an engineer.

[jovial path]

I hate risks. Actually I go to school to not take risks really, to be solid and stable. I see a lot of books about Steve Jobs, and other sucessful CEO's and these books tell: risk taking is important, but for me is a thing I should not really do at all, never, if feels like skydiving with not a very reliable material, actually you go to school to have the best skydiving material, this is not a risk at all.

[tardy badger]

Learning itself is a risk. You risk being wrong and wasting time

[jovial path]

I learnt english making a bunch of mistakes, but you can't make mistakes often with money.

[tardy badger]

But the reward of learning is that you understand that living is always a risk. Walking, breathing. Risk exists, but the things that are normal are just risks we’ve learned to mitigate

So long as you don’t break the law, money risks are minor

More money is printed every day

[jovial path]

I do not see like this at all.

[tardy badger]

But it’s true

My life is a good example of that

[jovial path]

You are an engineer and probabily you have a great financial life, but even with this I am not educated to risk money with a lot of money or with just a few money.

[tardy badger]

I almost lost everything due to trusting the wrong people. It was a risk I took. And going to school for engineering was a risk

But money is a risk you learn to manage

Just like driving

And engineering

[jovial path]

This is a rule.

[tardy badger]

Plenty of engineers have ruined their life

[jovial path]

My university pay projects, companies give money to research and projects. You see? No risks.

[tardy badger]

And not all engineers are privy to financial reward

And there is always risk

[jovial path]

No money going out of my pocket.

[tardy badger]

Everything you do has consequences whether positive or negative

You have to accept that it is an undeniable fact of life. Everything has risks.

Doing nothing has risks

[jovial path]

For the companies and my university.

[tardy badger]

Literally everything has risks associated

[jovial path]

They risked their money in projects I worked.

But not me.

[tardy badger]

For you too, you may not perceive the risks because they are minimized but risk still exists for you

There is no such thing as having no risk

No risk would imply there being zero repercussions

Which defies the laws of nature

[solemn aspen]

There's no risk

But there's stakes

If he royally hecks up, they may stop giving him monies

But no risk

[jovial path]

It is like working for a company.

They invest in your work, it is a risk for them, for you, you just have to do your job.

[polar bloom]

It's also a risk to depend on there always being a company to give you work.

You may get fired and no one else will hire you.

By working for a company you may also risk losing out on lucrative ventures.

[tardy badger]

So if he messes up, he risks not getting money for projects

[scenic oak]

Or risks getting kicked out of university with nothing to show for it if he really messes up

And if you are somewhere where university costs money, there's another risk

[tardy badger]

No matter how you slice it, risk exists. Those risks are the consequences of actions.

[polar bloom]

Or the absence of actions

[solemn aspen]

I don't think a universe will kick you out if you mess up a project

Its just stakes

Anyways, idk why you are arguing so hard for this silly ideal, how many discord arguments have you won?

[tardy badger]

What’s at stake is a risk. I’m just arguing semantics. If you just assume nothing has risks you will have a very sore realization when risks do compound.

And it’s not a silly idea

Not understanding risks and risk mitigation can lead to serious injury over time.

Massive engineering failures happened because risk or stakes as you would put it we’re not properly understood or just ignored

[solemn aspen]

Is this another line you put on the discord argument score board?

[tardy badger]

Why do you assume there’s a score to hold?

[solemn aspen]

Why are you trying so hard to argue on discord?

[tardy badger]

I’m having a discussion on risk which is important in engineering. There is no harm in that

[solemn aspen]

You're just looking to argue

You don't have to continue

[tardy badger]

Sure, have a great day

[solemn aspen]

Happy fourth

[jovial path]

This is why you need education.

[jovial path]

That is true.

Wow guys calm down...

Skerr is great so are the others (I think) do not argue for silly reasons.

[jovial path]

This "no one else will hire you " probabily happen if you are a wrong person

No one wants wrong engineers. Everybody values right people.

Like: no plotting against someone, making another employee be harmed...

This is a very bad situation.

I remember reading about that person who made NASDAK fall, his son participated in the wrong actions, he was gratuated from the University of Michigan and nobody wanted to hire him anymore, because he was wrong.

Non-typical 4th of July dinner: Pizza! Start with the dough

Pizza has been my july 4th dinner since like forever lol

I was remembering studying for the entrance exam for my university.

I started studying very early, like in my 9th grade.

It was a very deep and hard studying.

I loved it. Good times :)

10th grade was the best time of my life , I was at a high school + technical school.

I studied about 14h a day everyday.

It was a school that was a high school + technical school it is called Instituto Federal, they are very famous here in the country.

[static flare]

i love Halloween

[tardy badger]

Christmas and Thanks Giving are two in the same in terms of expected mindsets and whatnot. So I celebrate the Christmas season from November 1 -> December 31st

Halloween from September 1st -> October 31st

[solemn aspen]

halloween is a pretty nice holiday

catholics should adopt it as their own holiday like they have done with almost every other pagan holiday

and toyotathon too

[scenic oak]

I wish it was acceptable to keep your Christmas lights up longer

because it's so much work to set them upppppp

[terse estuary]

I've seen some people who leave them up year round, I feel like it kinda depends on the style of light you like to hang up. The "icicle" style ones seem to rarely be left up but I do see the normal strand lights left up from time to time

[scenic oak]

I kinda wanna get/make some neopixel strands

I could probably be able to get away with leaving subtle light strands, but I also typically set up a bunch of things in my yard and I really can't get away with that all year round 😛

[limber jackal]

So... folks from this server? From July 5th through Thanksgiving eve (at the earliest) is Halloween season!

That’s a weee but too long. One month is too short but more than 2 months is just overkill.

Guys, my mother told me to take care with COVID, she said people think it is alread over because of vacines or what else, but it is not. A lot of good friends from my family are not with us anymore because of this virus. Use mask all the time, including inside your house and when you sleep.

The #!%# is that even products from industry can have COVID inside, this is so scary, I am afraid to order food from restaurants, the nurses that come in to our house everyday, the physiotherapist that come in every week... It is all scary.

Guys, quick question for powerlogging, if i were to calculate the total of the power that's used by an electrical component, for example, i have a power logger that logs the power used by a device in every second, can i just add them up or do i have to divide it by 3600 to get its mWh?

[crystal ore]

If you are getting one second of a milliwatt measurement of power, that's one milliwatt-second of energy. To convert to milliwatt-hours, you indeed need to divide by 3600.

(To help your intuition, think of milliwatts as like the miles-per-hour number on your speedometer. To get the total distance your car travels, you don't do "65 + 64 + 65 + 66" and conclude you traveled 260 miles in four seconds, but you have to divide by the appropriate ratio of time too.)
