Does white glue work too?

So I have a very pretty pen, but it ran out of ink, and I would like to know how I can make black, permanent homemade ink for ir. Anyone here knows how to?

>>1991870
Circuit analysis, understood

>>1991795
I undestard, I apreciate with great value your correction, from now on I will aply it, thank you

>>1991795
No no! I´m not being sarcastic! Seriously

>>1991787
So I should ask for an exact amount of current instead for voltage gentleman?

>>1991778
Excactly in which part of my statement I commit an error so I can avoid making it again?

>>1991146
What areas of "basic electricity" should I study to execute this project?
My knowledge in electricty goes through: Relation between voltafge, amps, Ohms and Watts, law of Faraday, Law of Ohm, Capacitance, electrostatic and more. Which part you think I should study, sir?
(And I published this post in science, but no one helped me, someone told me to try here, so...here Iam)

>food cling film
I´m going to write that down, thank you so much mate!

>>1990981
I apreciate your correction, thank you so much

>>1990973
Supercapacitors...that could do the trick...In fact I saw videos of Electro Boom, one in which he talks about graphite, eddi currents, tesla coils, electrical resonances and more. I apreciate your suggestion

>>1990970
No...? Is not for that, I´m just interested in this area. I know I didn´t express myself with efficiency, but I came here to learn more, not only hitting books, but to ask people too for help

>>1990965
I made this experiment to study how much can a group of capacitors deliver voltage (Obviously the circuit is incomplete now), I used classic plate capacitors, with 5V DC with 2.5A

>>1990965
Well, i already did...and I am triying to learn more of physics and electricity, thankfully I´m already in my vacations so I can do that better (BTW about what I built, the amount of voltage I managed to contain was just some mV, gonna try again with new homemade classic capacitors, obviously using DC)

Welp, as the good Forest Gump would say "Shit happens"

How do you delete a 4chan post? XD I want to start over

>>1990943
Theorically I want to power up a 60W lightbulb using a powerbank made of capacitors for 30 minutes

>>1990943
Let´s say 2 Amperes

>>1990939
I don´t wish to use only one, I wish to use more than just one to have that "Stable Voltage"

>>1990935
Ok, I understand, and how I can predict how long it will take for the capacitors to discharge? (I want to have an stable voltage for at least 30 minutes)

>>1990930
I see, but I need to know something about the formular, what is "e" in the formula? "t" is a constant? What should I search to learn more of this?

>>1990921
How many Farads should the capacitor posses? Which type of capacitor is better for that?
And how many would I need to have a flow of current capable of during 30 minutes?

>>1990921
Ok, I understand gentleman. So let{s suppose I want to power up One lightbulb of 60W for about 30 minutes
