Yeah you can make a battery with just about any 2 dissimilar metals in an electrolyte

#

I once made a battery with copper sulfate, zinc, and copper and it ran an LED for 3 days

#

(2 cells to get the voltage up a bit)

quartz wren
#

the limiting factor was the copper sulfate being converted to zinc sulfate, eroding the zinc and precipitating copper in powder form

I didn't expect OxyClean to act as electrolyte XD

I like to study with this girl online (and a bunch of others), generally it is very good to have a reference studying(so I have someone to defend me when my brothers tell me I'm studying too much) and we talk in the study breaks(they are YouTube lives), when I study 50/10. Our timezone is different but I study the 12h-15h, she finishes by 18h here but I keep until 21h. Take a look: https://youtu.be/Ls3jvdMDRj4

wow

#

so

#

wow

#

that just blew my mind in multiple spots

#

this is the kind of stuff I used to make with my brother on sundays when we weren't allowed to play outside growing up

#

but a lot more complex than the kind of stuff we did

#

we got the idea from an I Spy book

#

though we never had table flips or bits that seemed to completely collapse, but intentionally and in a way that makes the system work

#

also the spaghetti noodle redirect was brilliant

also how are yall doing?

quartz wren
#

life is rough...so just the usual...

dusty citrus
#

Yeah we were required to find something to do on indoor days.

#

There was no complaining or tolerance of non-inventiveness there - you were going to find something that interests you.

#

A jigsaw puzzle met the requirement, that was a frequent fall-back on a rain day.

#

And there was no video game this or television that.

#

No being glued to the tube.

#

When we were in the basement we were doing things ya probably weren't supposed to be doin ;)

#

And if you hung around the house when the weather was clear, you were told you could either pull weeds in the garden, or leave the property and go out and do something. ;)

#

If the phone rang once a month from another parent, that was an unsual month.

#

So I'd traipse off two or three miles, easily. ;) all the time.

#

Spend a whole day in the forest.

late fulcrum
#

I was often glued to tubes, building circuits.

quartz wren
#

I had a good mix of outdoor adventures and being glued to the tube...while some of my friends in elementary school were getting their first cell phones, I was getting my first PC which was about 10-12 years out of date...

#

and I had to build it from scrap components lol

#

I remember having to scour HDD labels for the various numbers I had to enter into BIOS to get them to operate correctly

#

(Cylinders, heads, sectors, etc.)

#

and often it simply wouldn't work even with everything entered correctly

#

I even remember the first HDD that worked and how many sectors it had. it was 16,777,216

#

iirc there were 4 cylinders and 8 heads

late fulcrum
#

My first computer was fairly current at the time. Originally it was just the front board, maxed out with six 6810 chips for a whopping 768 bytes of RAM.

quartz wren
#

I want to build a backplane computer some day...a bit before my time but it would be very fun

#

(and yes, I mean design it from scratch)

#

actually...

#

I have an interesting chip stack I put together a while back that has a 6502, 6507, and 256B of RAM for a pseudo-cache

#

I should design a backplane computer around it

#

need to get a board etcher put together with some of my printer parts

#

so I can just fab the boards myself

#

but it would definitely be a fun project

#

probably do a CPU board containing that chip stack, a 4K ROM chip, and some extended addressing logic then a board with peripheral I/O using a couple VIAs or similar and a deep memory flash module

#

and eventually a graphics board but initially I'll probably just use the terminal rendering chip I found in an old endpoint terminal for a mainframe

#

or I could cobble together a custom board that does terminal output with an editable character buffer

#

since I'll probably want VGA output anyway

late fulcrum
#

That computer has a little converter board hiding in the box to translate between the Motorola bus (front board) and S-100 (RAM boards behind it). I have a cute little 1802 based computer that generates RS-170 video.

quartz wren
#

I had a silly thought for generating video for this

#

I might just add an ATMega chip to generate monochrome composite

#

it would probably be more powerful than the 6502 stack but meh

#

I mean, modern GPUs are far more powerful with parallel computing than the CPU, so it has a nice analog πŸ˜‰

late fulcrum
#

The 1802's DMA capability makes generating video pretty easy (you just need 3 chips, a latch, a counter, and a sequencer/decoder). However I'm still using an ATmega for early debugging, Ben Eater style.

#

Then again, I'm using a modern 32-bit 2.6GHz system as a serial terminal for my ancient 1MHz 6800 system.

#

Did you find the photo online or it is literally your computer there?

late fulcrum
#

The picture is literally my first computer. I still have it, and it still works.

#

Originally, it didn't have enough RAM to run BASIC, so I would write my programs in assembler, then hand-assemble them to machine code, then key them in using Motorola S-record format. Later, when the RAM boards were added on, I could load BASIC from cassette: it took about 20 minutes, and would sometimes fail.

apparently boops on tape are easier than waggling a pulsing magnet around

late fulcrum
#

The trouble with tape was they settled on the "Kansas City" standard, using 1200Hz and 2400Hz tones. Easy for a computer to understand (4 cycles of one or 8 cycles of the other for the same bit lengths), but terrible from an implementation standpoint (since the frequencies are harmonically related, any distortion will tend to generate signal in the other one, so the recording and playback levels had to be just right or you'd get errors).

Ok so I guess this is the forum for this kind of question: I have an instant pot. I’d like to hack its programming head thingy so I can upload my own recipes in it. For example some of my recipes might call for 15min sautΓ© and then 10min low pressure cook and then 50min on the natural pressure release. Then I’d like it to beep to tell me my dinner is ready
I dislike that there are only single function recipes in there except for the yogurt mode which has the boil and set modes

late fulcrum
#

So, what is your question?

jovial path
#

I think we had to take out the microcontrollers?

#

We need to have acess to the program

#

And there make the changes...

#

You would have to solder out the components I think and put the Eprom coder and maybe make the changes...

#

I really do not understand the hardware of an instant pot.

jovial path
#

I see no microcontrollers

late fulcrum
#

There may be a "blob" style microcontroller. The usual approach is to remove the control board and build a replacement with interfaces, relays, triacs and drivers for whatever you want to control.

jovial path
#

I mean the circuit

late fulcrum

That may be easier than reverse engineering something. I suspect there are only a few inputs (temperature, pressure, whatever) and a few outputs (heater, release valve, whatever)

late fulcrum
#

I think that's on "tape and reel" packaging. There are various quantities, such as 3000 per reel, so all they have to do is count out 25 reels and send them to you.

#

As for changing the programs for things like instant pots, I would just craft my own to execute whatever sequences I wanted. There would probably be some interesting problems to solve, such as a PID scheme for temperature control.

As for reverse engineering software, you can do this with model based software engineering

The idea is to model functions and what they do. From there you can break down the model into smaller function modules.

How an electron can have more energy than other electron?

#

We know that V = J/Q

#

The resistor takes out the J

#

But the Q remains...

#

That is why the current in a single mesh with multiple resistors is the same.

#

Where this energy is stored in the electron?

#

Is there any physicist here ?

jovial path
# jovial path How an electron can have more energy than other electron?

It is not temperature... It is not gravity.... It is not speed( is it speed? I know a formula to get the speed of a current as a function of V, maybe when J decreases a bigger package of electrons travels at a slowe speed and when J increases a smaller package of electrons travel in a bigger speed ). What do you think?

#

Mantaining the Q/t relation.

thick wind
#

@jovial path what are you talking about? Where do you see electrons in this equation?

late fulcrum
#

Q is charge, electrons carry charge so charge depends on the distribution of electrons in space. It's like potential* energy. Electrons in motion provide current, which is a more dynamic form of energy.

#
  • pun intented
thick wind
#

Q is electric charge, which is defined by some quantity of electrons. Each electron is approximately 1.602E-19 coulombs, and the sum of a large number of electrons is what makes up the Q in that equation.

jovial path
#

An old physics professor that I had when I took Physics 3 told me this is related to E=mc^2

#

Just now in an e-mail.

#

I think is so weird when you relate to different areas of physics with the same unit

#

Ex= E = mgh and E = C * delta (U)

#

How this relates!?!?!?!?!?!?

#

How 1 J in both of them is worth the same?

jovial path
#

C is a package of electrons

#

A defined package of electrons

#

Is like 1 Coulomb is 5 electrons

#

It is the charge of this package.

#

But I like to see it as a number

#

Because the charge of a electron doesn't change.

#

He just goes to other places.

ancient kindle
#

1 coulomb is the charge of 6.28 * 10^18 electrons

thick wind
thick wind
#

As for E being a unit common across multiple areas of physics, we can use certain relations to calculate the translation of mechanical energy to thermal energy, and thermal energy to electrical.
If you calculated the energy needed to move a mass across a surface, the energy losses from friction are converted into heat. Likewise, if you calculate the energy of a current passing through a resistor, you could also quantify the energy loss by the heat byproduct. These units and their relations are not arbitrarily defined; there are real relations that compare all of these different types energy to a singular unit.

#

E=mc^2 is another behemoth entirely; I have not read up on how Einstein derived that, but it's much more involved compared to mechanical and electrical energy conversions.

#

This is way more physics theory than I ever did at school in a single sitting...

#

My head hurts, time to take lunch.

late fulcrum
#

Similarly, while the charge of individual electrons does not vary, their position does, and moving them around can store and expend energy. If you have two capacitor plates and you pull electrons out of one and put them in the other, it's the same number of electrons, but you've stored energy in the electric field between the plates. If you move the plates farther apart, that will lower the capacitance, but the amount of energy stays the same (so what does this do to the voltage?).

#

You can even take the capacitor apart and put it back together.

#

It is indeed complex and subtle, but the overarching laws apply everywhere.

thick wind
#

A suitable analogy would be suspending a mass up high somewhere. It has the same mass as if it were on the ground, but it's potential energy is very different. Releasing the mass would convert its potential to kinetic energy.
Likewise, a voltage is not an indicator of how much energy a circuit has, but rather how much energy it can potentially produce if you put a load across it.

jovial path
#

The number of electrons is directly proportional to Coulomb.

jovial path
#

But I don't think Q in the plates would be the same because the electrons would not be inducted by the protons anymore.

#

They would rather go somewhere else...

jovial path
#

When you do Thevenim Equivalent.

#

(In theory)

#

You open the circuit

late fulcrum
#

Just don't confuse capacitance with Coulombs

jovial path
#

It doesn't increases with the distance.

late fulcrum
#

A point doesn't have a voltage: voltage is only measured between two points.

jovial path
#

If you choose to put a ground in there.

#

But it is your choice.

#

You could put ground somewhere else.

#

And make Vth = Va - Vb

late fulcrum
#

"Ground" is a confusing concept, often used as a shorthand for "zero volts".

#

However, it is not a choice: voltage is always measured between two points.

jovial path
#

Yes..

#

Then Vth = Va - 0

#

If you put a ground in Vb

jovial path
#

It can take out electrons as well as take in.

#

It makes everything neutral in physics.

#

But I don't think engineers see like this.

late fulcrum
#

It depends on what you're trying to accomplish. If you want to understand the basic physics, you think one way. If you're just trying to get a circuit to work, you can take a lot of shortcuts and get away with it. Engineers are normally being paid to get something working, so they're fine with the shortcuts.

jovial path
#

Ex: there should be a DDP between the negative pole of the batery and ground

#

But engineers put a ground right on it.

#

It should decrease the capacity of a batery in at least a half!

#

If the charges are equally distributed

#

My hipothesis.

late fulcrum
#

I'm not understanding what you are saying. What is a DDP?

thick wind
late fulcrum
#

You could, if you wanted, assert that electrons are energy, as they have mass, and mass can be converted to energy. However, in ordinary use, that does not apply.

jovial path
#

When you calculate the V above a resistor

#

You calculate the potential in one point minus the potential in the other point.

#

This is ddp

thick wind
#

So, a voltage between two points.

jovial path
#

Yes...

#

Is DDP used only by brazillians?

#

Have you never heard this before?

thick wind
#

It sounds like a language-specific acronym.

jovial path
#

ddp?

#

In portuguese is "diferenΓ§a de potencial"

thick wind
#

We just use voltage difference or something, not even sure if we have a separate term for it

#

Difference in potential = voltage haha

#

In any case, I'm not sure if you would use a thevenin equivalent for a capacitance.

jovial path
#

You can :P

thick wind
#

If you had an infinite distance between two plates, you could hold an infinite voltage before discharging, but the voltage is still determined by the difference in potential on either side

jovial path
#

Just take out the capacitor.

#

Just like the resistor.

#

Ans create the equivalent circuit.

#

That is how you solve complex RC circuits

#

Oh...

#

No I know what you mean

#

You mean

thick wind
#

Ahhhh charge/capacitance

#

Okay

jovial path
#

Make the distance between thevenin's poles?

#

Just like I said before?

#

Bigger?

thick wind

If you have a capacitor with infinite capacitance, you need a lot more charge to actually charge the capacitor.

jovial path
#

I think the Voltage in the capacitor there's nothing with joules in an impossible way

thick wind
#

The way a capacitor works is the the charges on one side are attracted to the lack thereof on the other, but with the plates infinitely far apart, the attraction force needle to charge said capacitor is also infinitely small

jovial path
#

But the voltage in Thevenim there is a relation with Joules

#

Study break is over.

#

Have you ever worked with a current source?

#

In other words: do you know any source where you can choose between voltage source and current source?

late fulcrum
#

Some power supplies and amplifiers work like that, but normally a voltage source is (theoretically) zero impedance, and a current source is (theoretically) infinite impedance, so they're somewhat different.

thick wind
#

The one I like to use most often has a current limit and a voltage limit, and if you want to use it as a current or voltage source, you just set the one limit and adjust the other to be higher than you need to drive said current/voltage.

#

I don't think there is such a thing as a perfect source, but benchtop supplies usually give you more than enough control for any kind of circuit testing.

jovial path
#

If I have 3 voltage source in parallel with different V.

#

What is the equivalent tension?

#

(I didn't find on my Physics 3 book, and it is very good. It is the best of my country probabilly)

#

(Maybe I didn't search properlly)

#

The book told me that if they are in paralell

#

All V are equal

#

And all the current sums...

#

But how do I calculate V ? It is an average?

#

My friend who is an engineer works with solar energy

#

This is very popular here.

#

I forgot to ask him this.

tardy badger
#

Working with different voltage sources?

#

Usually with superposition if I remember correctly

late fulcrum
#

The impedances of the voltage sources affect their individual contributions

tardy badger
#

Right, calculate the affect of each on the total system and them bring them together. I haven’t used super position in a while πŸ˜…

#

Maybe a year or so

#

It’s kind of ridiculous how so many fundamental tools of circuit analysis just don’t end up getting used in your first few years of working. It’s only when you are in a position to design those systems that they even become something you use again

#

Even then, computers do most of the analysis. You may have to build a test bed to run against your circuit but you usually just put in the parameters into an equation library someone else before you defined lol

#

The thing I use most consistently is ohms law and some RC calculations for filter design but that’s it

#

On a rare occasion, RCL for DC-DC converters

jovial path
#

Because all the voltages will go to 0 but the one I am analysing.

tardy badger
#

That’s the point of super position, isolating sources

#

That’s the whole reason we use it in circuit analysis

jovial path
#

But it was a good hypothesis.

#

If that worked I could analyse the tension in a resistor individually

#

And them sum them up.

#

And them find the Veq...

#

But it won't work

tardy badger
#

Try doing a source transformation

jovial path
#

No resistors do to it.

tardy badger
#

Add a 0ohm resistor

jovial path
#

The result will be 0

tardy badger
#

It’s the same circuit and it allows you to do the transformation

jovial path
#

Or infinity

tardy badger
#

Or a very small resistor that will be negligible

#

Like 1Mohm

jovial path
tardy badger
#

Sorry

jovial path
#

It = V1/R + V2/R + V3/R

tardy badger
#

mOhm

jovial path
#

This will be the current

#

Wait...

#

No

#

There will be current flowing to the resistors...

#

But it will be very small

#

Veq = (V1/R+V2/R+V3/R)*r

#

The problem with current sources (as I did in simulations)

#

Is that they adapt the V to the circuit.

#

And offer the exact value as it say it offers in the current.

jovial path
#

It will not work :(

tardy badger
#

Can you use practical voltage source vs ideal?

#

If you can use practical you can just add a resistor of some arbitrary value, call it Rs

jovial path
#

I see.

#

But as I said, it will be a short circuit if I do source transformation

#

Very close to a short circuir

#

10 minutes break is over.

#

#

... I should really study 120/24... Or 100/20

#

I would be happier.

#

Bye.

tardy badger

I’m mostly just shooting in the dark here because I don’t know what your circuit looks like

There is not a circuit.

Because no body teach me this.

#

MIT OCW doesn't teach me this.

I want one, but my budget's tight

jovial path
#

I think Limor Fried made a little mistake in her answer to my question in ask an engineer

#

You can connect in parallel with the same values

#

The V will be the same and the currents will be summed.

#

As for my especific question there is not a calculus to find it

#

I didn't found the calculations

#

Under there you can see badly connected voltage sources...

#

She was parcially right and parcially wrong.

#

Too many voltage sources in parallel can burn the circuit due to Joule's Law.

It is. But is not recommended.

#

There were problems in my physics 3 book with voltage sources in parallel but with the same V.

#

Never with different V's

#

Like this.

#

Above there in the right 1.5V

#

But 3A

#

Not 1A.

#

Weirly enought

#

If I simulate in multisim live two voltage sources in parallel it will not run the simulation.

My calculator refused to divide by zero. Maybe it's something like that.

But as I said it is not recommended.

While it's not recommended, you can sometimes get away with it, like the time a SparkFun engineer hooked a bunch of 5V chargers in parallel and made an arc welder.

Ah don’t be, usually USB sinks 500-900mA of current

Less than 5W of power usually.

That is true.

But I've heard that even m currents can heartattack

tardy badger

Sometimes they can sink up to 5A if the right USB C PID configuration is there

10mA to stop the heart

Is it ressonance?

I worked in a project like this in university. There was a very young boy I thik 20 years old (about my age) who used a arc welder to sold all these parts of the car

#

It was so lighting when he used it

#

Is it eletricity?

jovial path
#

Is it a short circuit?

#

Why it doesn't damage the battery?

tardy badger
#

Arc basically causes a surge in current that runs away and dissipates as heat. Usually faster than it can be absorbed by the air

#

Causes the material to melt.

#

Arc welders can usually be used under water too because they create a halo or kind of a gas bubble around the contact area

#

But in terms of destroying or damaging the battery, it depends on what kind of battery used and how well the arc welder is setup

#

You can make a spot welder with a large enough Lithium Polymer battery

jovial path
#

How was he so precise?

#

I could not see close because I was afraid of hurting myself

#

All the car gets the current?

#

Why other parts didn't heat?

tardy badger
#

A bulk of the current is isolated at the contact area and the heat dissipates faster the further from the contact point you get

jovial path
#

.........

#

He can get seriously hurt

#

If he touches the car.

tardy badger
#

Yeah, he could

jovial path
#

.....

#

Very bad.

tardy badger
#

Any welder could get hurt if they are not careful with welding

jovial path
#

But he had a diploma doing this.

#

He made a course on how to use it.

#

He makes mechanical engineering

#

He was the only one there who knew how to do it...

#

He had a lot of protection.

#

There I tought it created a little voltaic arc

Does sleeping at a late time at night really matter if you're always sleeping at a consistent time every night?

And no, there is no other reason beside her worry for my sleep health. I can respect that she cares for my health, but she isn't being logical about it

There's actually some research showing that teenagers in particular naturally shift to a later schedule as part of the various hormonal changes, I believe. It was used to try to justify shifting school starting times to allow students to perform better.

Is she right to worry?

crystal ore
#

No, I'm saying she probably has it backwards... it's expected and natural to perhaps have a later than normal schedule at your age. Different people are "larks" or "owls", too, so expecting one best time for everyone is problematic. As long as you're not missing any obligations in the morning, it shouldn't be an issue, in my humble opinion. But arguing with your mother is often a losing battle regardless of the facts... πŸ˜…

If I have school the next day, I will sleep 9 or 10 to wake up at 6. But this is summer vacation, and I simply feel more comfortable around midnight

#

Man...

#

She comes to my room to take my phone every night, too, to "force me" to sleep. I'll often just read a book, though, and she'll come back and get mad :///

#

I'll see if I can talk to this out eventually

That's a lot easier to do when it makes sense. I respectfully believe her logic is flawed

Faith is the assurance of things hoped for, the conviction of things not seen.

#

It is hard to explain.

#

I just obey my parents and good things happpen, even that It doesn't makes logical sense to obey them in some situations.

#

I just do it like fire.

I can't speak to what's healthy for others, but I've noticed that my most productive periods are between 10PM and 4AM

#

but I'm told this is normal with bipolar

#

so likely not helpful information

Parents are often wrong anyway. You'll realize this when you get older and still haven't got a clue (none of us do). My parents were always very worried about me getting "square eyes" from watching the computer monitor too much (it was a thing in the 80s).

#

Also according to 2 different therapists I had, so long as you're getting enough sleep to feel rested each night on a regular basis, while it's healthier to have it at a consistent time it isn't necessary for proper function

The correct statement is "Parents are often right".

#

There is a very big probability they are right.

You must be smart to understand what your parents tell you and must be smart to obey them.

The EARS package is intended as a limited ready-to-use single word 
recognizer for Linux systems.  However, its design already aims at
being a host for all kinds of methods used in speech recognition (SR).

I don't think 'EARS' was written in Python, it's 2 different pieces of software
