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

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.

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in elementary school were getting their first cell phones, I was getting my first PC which was about 10-12 years out of date...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

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 😉

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.

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).

While you can translate this number to some number of electrons, the charge itself can vary, it's not some constant we multiply or divide to get from juoles to volts.
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.

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.

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 😅
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
Usually with superposition if I remember correctly
If I do superposition in paralell voltage sources I'll create a short circuit.
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

Or infinity
In the case will be a very high value V/R
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
Veq = (V1/R+V2/R+V3/R)*r
V would depend on the value of r (my resistor to calculate the Veq)
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

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.

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 eletricity?
Or is it heat?
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
tardy badger
Yeah, he could
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...

Does sleeping at a late time at night really matter if you're always sleeping at a consistent time every night?
And getting enough sleep every time
Say you sleep at 11 pm or 12 am, but very consistently, and wake up 7 to 8 hours later every night. No way the exact time you sleep has any influence, right?
crystal ore
There might be some effect of sleep schedule versus sunlight timing.
hasty quarry
Well, sure, it's best to sleep during the dark hours. Sleeping at 4 am may be taking it overboard
But something more or less than midnight doesn't sound like it would hurt to do consistently, would it?
crystal ore
I wouldn't think so. That's pretty much my own schedule, for instance.
hasty quarry
My mom took my phone and put a time limit of 10:20 pm, which is annoyingly early for me. I'm 17 years old, and sleep consistently around midnight, and wake up at 8 or 9 am, but she seems to associate a late sleep time with a bad sleep schedule. I want to convince her her logic is flawed
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
crystal ore
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.
hasty quarry
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... 😅
