@All What is the possibility of someone like me creating a new form of never ending battery? Because I accidently combined three items together in a very very small portion. It outputs 0.6 volts DC, and it has been 3 weeks almost 4 weeks. And the voltage has not dropped at all. The items used to make it are not going away or getting smaller.
The voltage source has been on a complete load of 0.6 volts DC for the 3 weeks so far.
Nothing is showing deterioration of any way, form or kind. I talked to the H-Bar and they have a theory on it, but they are not sure what it is. They believe it is a battery.
There is no possible way this thing I made has any large capacity. It definitely has way way less than 100 mAh capacity if any.
I believe that there is some form of reaction going on that is a form of atomic molecular movement or something. But I'm still not sure. It is all speculation at this point.
Let me know what you all think of this?
 
2:13 AM
@ScientistSmithYT at low to no loads, there are batteries with very, very flat discharge curves
 
2:55 AM
in output characteristics of BJT common-emitter for small signal analysis, small signals Vce and Vbe are drawn at Q point. I don't seem to quite understand the point that this graph is trying to make.
 
3:37 AM
@Shalvenay What are you meaning by a flat discharge curve? Are you trying to say that it will last a very very long time?
@JRE I have a question about power sources. Just one sec.
Or...
This is for powering a DC electromagnet that is going to be used to magnetize or re-magnetize temperature damaged neodymium magnets.

@ScientistSmithYT Your "costs" are all over the place, and mostly seem to be "apples to kumquat" comparisons - you don't define how much power or energy you need, nor how much each alternative can deliver.
There are DC generators available.
All of your "battery" solutions are going to require some power source to recharge them.
I don't know why you've flagged "outlet power" as "costly." Or why you think it is hard to get parts for, or why it in particular is "dangerous."
Have you given any thought to the total energy stored in a battery bank that could "take weeks to charge?" That's dangerous af all by itself - not to mention the environmental hazard of that much lead.
Super capacitors the same. What happens if you accidentally short your super capacitors? Biggest, baddest arc flash you every saw, slagged cables, probably slagged capacitors, too.
Your "$25000" solar solution is something like a 10 to 15kW setup, and would probably fit on the roof of a typical single family home.
Taking 10kW then as your needed power, a generator wil cost you from about $2000 upwards.
A 10kW battery setup will also cost you several thousand dollars.
Just flipping use the outlet, OK? Worst case, you need an electrician to connect your gadget to a high current breaker in your house. Still easier than all the crazy stuff you are considering - and about as safe.
 
6:34 AM
Writing firmware for embedded is on-topic, right? Would asking how to flash code onto a board fall under that?
e.g. this -- I want to flash the bare metal instead of using CircuitPython, and I have M0 firmware I want to put on it, but the only instructions they have seem to involve writing Arduino code in a web editor and downloading a special file
Would it be on-topic to ask for instructions on EE.SE?
 
6:55 AM
why dont you guys help me solve this problem of mine?
0
Q: Transfer function of ideal op amp

TeilZeitGott This problem requires solving for V2/V1. My approach: R2 and R4 parallel reason: R2 has virtual ground and R4 is connected to the ground. Applied Nodal Analysis and got the following answer(incorrect). The correct answer should be: How should I tackle this problem?

 
7:08 AM
@JRE The reaaon why I said Outlet power is because outlet power is AC I will use a fullbridge rectifier which is a very very huge cost for the 20 kW system I need. In my area I can get a 23 kW system for $25,000. I need to achieve a magnetic field strength of 4 tesla at least.
@JRE I need a very large breaker greater than 200 amp.
@JRE The other reason why I say its expensive is because in my area it is $0.12 per KWH. Which in 1 month will cost $438.30 at least or $594.40.
 
7:23 AM
@JRE It is not a toy I'll give it that much. And it definitely is dangerous either way. But which way is better with the danger level I wasn't sure. The things I make are what I call potentially very very dangerous. Because if they are handled and worked on properly then there is no danger that is worth worrying about.
@JRE Just like how we don't consider an air compressor super dangerous. Because they normally don't explode. But they can explode which is what I am saying by they are potentially very very dangerous.

:5108114 Your magnetizer won't be running continuosly, now will it? Compare $500 that you can pay out as needed to paying $25000 up front. The solar system doesn't become cheaper until you've operated it for at least 4 years - full blast. How many magnets are you planning on zapping?
"Zapping" is a good word, by the way. You only need a short pulse for the magnetization (as I understand it.) But, apparently it takes kilovolts to do it, so AC is a better bet any way.
 
It will have the two options. Pulsed and constant.
I will most likely be using it in my spare time to run on constant mode.
 
JRE
Why? If all it takes is a pulse to remagnetize a magnet, why would you run it continuosly?
 
The size of magnet also effects how long I need the pulse to last. So I might use constant for magnets larger than 1 by 1 inch cylinders or cubes
I have a few 2 by 2 cylinder magnets, and 1 6 by 2 disc magnet.
I can use it in pulsed, for small magnets, or constant for larger magnets, or constant or pulsed for experimentating purposes.
 
In my area, everything is hooked up locally. I need my system to be set up on a desperate system.
Ok I read it
There are coils, more like sheets that can be made to do this stuff.
That's how they make MRI 2-5 tesla machines and the 45 tesla Hybrid electromagnet in Tallahassee Florida. As well as the 100 tesla multishot electromagnet.
They have the budget to use a generator to fill large capacitor banks that dump into the 100 tesla multishot electromagnet. I don't have that kind of budget.
*sorry I meant "seperate system"
 
JRE
8:00 AM
What you need is a system that can deliver a pulse large enough and long enough to magentize your big magnets, then charge it to a lower level for the smaller magnets.

Just build a compulsator. That's how the Navy fires rail guns...

My IT department just told me that they don't want to backup data longer than 3 months and don't want to give me data if something got corrupted (previously we had a few years). So our group has to buy our own hard drive and backup data ourselves. What is the point of having an IT department, if they can't even back data up?
 
5:58 PM
@VoltageSpike New name?
Anyways, computer backups make sense to be somewhat limited, but you should have repositories or something for archived and current designs, right?
 
@W5VO Yeah, the old name wasn't very "creative", thought I'd make a name that relates more to EE.
As far as backups go, before we could go on to our server and request backups up to a year. Now they are telling us 3 months. I don't use cloud services because I have had these features. The problem is if you don't catch corruption or deletion (which have happened in the past) before the 3 month marker, the data is gone forever.
It all started when I requested a backup from our IT department, and the IT guy made a fuss about it (I think it took 30mins of his time)

@rdtsc The railgun specs even if simplified would be too much. It goes over the gauss rating of my equipment I want. Maybe if I get more government funding through NSF I can build what I want. Which is a 100 tesla 2 microsecond pulsed electromagnet.
@JRE It sounds very promising. But my magnetic field needs to be pulsed up to 50 milliseconds or 90 milliseconds. For full saturation of a N52 magnet to occur. Of a 1 by 1 inch cylinder size. Something that holds a pulse for less than 50 milliseconds will not work properly.
@JRE As for the homopolar DC generator I'm not sure it will give me enough energy potential to equal what I need. It is something that produces very little energy potential.
If it was easy or hard I would have it solved already, but this is a complicated thing to build. It has variables that change day by day. There is little to no evidence or works done on how to make something like this. Even though its done all of the time.
Even the scientists that made the 100 tesla multishot electromagnet never told anyone how they built it. They show the outside, but the inside is what is most important. They hide what can be considered the instructions on how it was built. This is what I want to stop by making my own and later sharing my instructions on how it works and how I built it everywhere.
