Switch puzzle

Connect the switches so that the bulb lights up only when all switches are up and when all switches are down. Tricky puzzle that has fooled people for over 30 years. Wires are the only thing allowed Yes there IS a solution

I need a hint. Like, what places the 3V source connects and what places the lamp connects.
MR_SN0WY

3v source connects to anywhere and the lamp connects to anywhere, so long as the light is on when the switches are all up and all down, and the lamp is off in any other state

I will know the solution when I wake up. Good night.

So when are the lights off then,!!!?

MR_SN0WY thats fun pure, hope you have tested a solution here in everycircuit simulator.

I think I got it!!! But I had to use a resistor so the simulation wouldn't crash. However, in real life a resistor would not be needed. Does that count? http://everycircuit.com/circuit/6015134588993536

Here's a solution using 6 switches (not 5) but no resistor. http://everycircuit.com/circuit/5618019966648320. I haven't tested it very thoroughly.

Any even number of switches is trivial

@592azy..., your first “solution“ requires more resistors 😋 http://everycircuit.com/circuit/5189934100250624

592azy2circuitdude, I tested your circuit and it works flawlessly except for the need for one more resistor connected in series with the bottom terminal of the switch that’s second from the left. I tested every possible combination by counting through the switches in base 2 and the only combinations that light up the LED are all low and all high, and there is only one state that requires an additional resistor.

Thanks for catching that. l'll add the resistor.

Your welcome.

YES, sure i have also tested all combinations and congratulation @592azy2circuitdude i think you solved it! But Mrsnowy, haven't i asked you if you tested the solution within everycircuit, cuz i was expecting the need.of resistors! Next time you should test it first before just publishing. Holy sh..

The circuit looks much nicer, but what “details“ you mean. There is nothing new!

@hurz ... like I said 'more detail' such as clarity, with just the need for one resistor as described rather than your vague mention of 'resistors'.

Right you cant read circuits i forgot.

He understands circuits. You just read them. You might know more letters than us, but you can not write. You just learn texts others wrote. Poethic.

Zerlege weiter einsam deine Fernseher, es ist ja eiskalt in D wie ich gehört habe. Pickelgesicht
LeButch

Der Fernseher war in 30 Minuten zerlegt. Und es sind 30 Grad im Schatten. Wie lange brauchst du denn für einen Fernsehr?
hurz

Wie lange ich dafür brauche, bei 30°C im Schatten? Du bist schon ein echter Vollpfosten

Naja, dank dir haben meine Freunde und ich immer was zu lachen.

Sounds like you have to tell us more about you and your “friends“ even nobody asked you.
LeButch

Sounds like you are talking English again to make my answers look offending by saying them out of context.

That is really poor. If you reduce me on my age, you may not forget that I am going to university this fall, one month after my 18th birthday. That I finished school so early should be enough evidence for my competence. Also, even with my small age I defeat you in discussions. Good that you are old, that means you have enough time to think about your answer.
hurz

And you are just a troll
LeButch

This can not be the last argument every time. It is not that easy to discuss. You dont even know what a troll is, so google it.
hurz
7 years ago
What discussion? Havn't you promised for a while to shutup for forever? Are you so bored at 30°C without friends and just a TV to disassemble you have to troll again? Troll, pickeliger
LeButch
7 years ago
Every discussion you loose you just tell people they were trolls. You are unable to discuss.
hurz

And the topic was “LeBitch is just a Troll“
LeButch
7 years ago
The topic was that you reduce me on my age knowing that I am more competent than many others in this app, but you just said I was a troll cause you had no arguments.
hurz
7 years ago
The topic is, you jumped on this thread like a troll.
LeButch

A troll is not just someone who has an opposite opinion than you. Otherwhise, all users of the freedom of speech would be trolls.

FYI, you are a troll

@hurz, like I said earlier in another circuit about some people being so stubborn that they’re not worth being helped because they won’t accept that help, and that @fancycontrollers was one of those people, well, you seem to be one of those people too. You have so much knowledge, but you put it all to waste because your mean to others and you’re too stubborn to change that, and that gets in the way of your sharing your knowledge with others. Without you around, I’m sure 90% of the arguments on EC would not exist. Although, I have to admit, it does provide some entertainment.
hurz

@jason9, again and again you seems to not read the thread. Here we have just a troll which, you are right is just an idiot. Here is absolut no discussion. Please tell me what you see here which makes sense to discuss??? Its just a troll we better ignore, you are absolut right in that point. Anything else you would like to talk about??
LeButch

And again you do not say something about his arguments but about me being a troll. Lets see when Jason is a troll too for being my opinion.
hurz

If i understand jason correct, i should ignore you.
jason9

All I see in this thread is @LeButch trying to make sensible discussion and you, @hurz, just insulting him and calling him a troll. Of course, there was that German part which I can’t understand, but it’s probably more of the same. And also, in my last comment I addressed YOU, @hurz. Not @LeButch.
hurz

Jason, LeBitch in unable and do not want any conversation. Its just bitching what he is doing.
LeButch
7 years ago
At least I am reacting to your comments and not just calling you a troll.
hurz

Im not interessted in your endless bla bla blah. There is and was no discussion between us. If you are bored, look for another TV to disassemble. Troll. Thread closed.

Why try lighting up some more fluorescent bulbs with that HV supply of yours? Probably a good way to pass time.
LeButch
7 years ago
@Hurz what is so funny with the fact that I disassemble old electronics?! I have hobbies. @Jason I did it once to see if it worked. Now I dont need to do that anymore.
jason9
7 years ago
Sorry, I made a typo. I meant “Why not try...”, not “Why try...”. Anything else you can do with Hv power supplies? Maybe zap the components you get from old electronics. If you find a component isn’t working right, zap it!
LeButch

It is a 3€ HV supply from amazon. But yes, I could do that.
jason9

How many US$ is 3€?
LeButch

Idk, but defently under 5
jason9

Pretty cheap then. $5 isn’t a lot.
LeButch
7 years ago
Correct. It runs at app. max. 25 Watts. This is not bad for such a cheap component.
