Aspergers is 'the engineers disease', so you will probably find that a higher proportion of people here are aspies 

There are various levels of 'functionality' and many have worked out that if you want to participate in social endeavours, even on line ones, a certain level of polite behaviour is required, even if you don't want the other participants to be 'your friends' 

You are spot on !
I work with a lot of engineers, and a lot of them are aspies.

But, we do try, the most of us, to behave in a polite way. That is not to say that we  can say, by accident something that offend somebody. But when told, it hurts us the most.
Most aspies are realy clever people, but socially awkward.  But we try to do our best to blend in. 
Those who don't,  must really struggle in the day to day life, and i do feel for them.It cant be easy.

If one is so clever that one roams these premises, i would think that one would be so clever that one understood this.
But maybe i`m wrong..   

Annyhow, soon Xmas.. the snow is here and its peaceful here in Norway. And i hope that it stays that way for everybody..

One of the first things a psychiatrist will tell you about DSM-IV (Diagnostic and Statistical Manual of Mental Disorders) books is that laymen should NEVER EVER read them because there is 100% chance of multiple, completely wrong diagnoses. If you read DSM-IV you will find that you have symptoms of all kinds of mental disorders. Asperger's syndrome is revealed in manifestation of certain traits, emerging behaviors and can only be properly confirmed by a trained psychiatrist. Being socially awkward is absolutely no way related to having AS. People online who call someone highly functioning autistic or having ADHD or Aspergers without any proper training are just stupid assholes who talk out of their ass, ignore them. Statistically, there is virtually no people on this forum that have any serious mental deviations. I have a short fuse and very direct way of saying things, and I think Kiriakos is just lonely (at least internally) and has a lot of misplaced enthusiasm. I don't truly believe he is a moron or inherently evil bastard, I think he is just "attention whoring".

We are ultimately here to draw information and share experience for the common good. We strive as a group, but on individual level no one gives a shit about anybody else. If one of you died tomorrow in a car fire, Dave or anybody else wouldn't give 2 shits about you, just face it. It's not because we are emotionless drones, it's because there is no personal emotional attachment, we are just "avatars" online. And don't idolize anyone, please.

There is a petty argument that pops up here and there and we need to either make it comedic or stop it right then, otherwise S/N ratio of the forum gets really low. There are some moderators here who shall remain unnamed who have 1000+ posts and there is literally and dozen of post that are of real value, the rest is just generic, irrelevant fluff.

This thread is not about aspergers, Christmas or me or Kiriakos. This thread is about finding a solution to the puzzle. So far I have seen ONE weak and not really applicable solution. Please get back on topic.

Lucky for me I speak more than 1 language and I can read Polish. He stated that the circuit has missing components but is serial like drawn, and some components have been added but not visible. I am not asking to guess how 3 incandescent bulbs in series can be controlled with series switches, am I?
The point of this exercise is to find our own plausible implementation of this. Here's one:

[joedevola]

Hey Wartex, you have just added to the S/N ratio 

Anyway, I was not 'diagnosing' anybody, simply making a comment to someone who revealed that they have been diagnosed.  For what it is worth, the statement about engineers having a higher incidence of Aspergers is a statement of fact, not a diagnosis. You are correct about lay-opinion about reading the DSM, however my observations are based on both living with my son who is diagnosed with AS and having been diagnosed myself.  Having said that, AS does appear to be the 'flavour of the month' diagnosis, like ADHD was 

Even if you don't want to be my friend, I wish you a merry Christmas 

PS, I am interested in discovering the 'trick' of that video too

Just worry these kind of activities will affect/hurt Dave's reputation among manufacturers, cause there is a possibility that this kind of "beggars" are riding this website's popularity, and they're sorta claiming that its a collaboration work with Dave in order to keep these scams going, who knows ? Especially those Chinese manufacturers that most of the times we know that they're quite poor in English and its quite logical that within thousands of attempts which cost them zilch, they might scored a few successes.

This is exactly what I thought. The video posted on Youtube fails to assign you the task of thinking a little deeper. It fails to tell you "hey these components might not be what they look like", and the shematic makes it easy to assume the whole thing is fake/edited with after effects.

[JuKu]

Hi Wartex,

Congratulations! Your circuit is much simpler than the one I explained this to myself (three oscillators, three band-pass filters). The batter is likely just a battery, but there is an oscillator somewhere, either inside the first switch (he had to remove the sticker to pry it open?) or inside the battery connector. Just guessing...

Why bother, it cant and will not work, ever and never

Gee,that was fun!
Getting back to the original topic,however,I still have a problem with your circuit,Wartex.
I can see how Sw1 & Sw3 would turn on their associated LEDs,but I have a bit of a problem with Sw2.
How about a description?

[EEVblog]

Ok guys, knock it off.
I'm seriously contemplating going through and deleting every personal attack post in this thread regardless of whether it has content or not, and the thought of having to do that just pisses me off and ruins my day.
Cut out the personal attacks, please. I don't want to have to heavy hand moderate this forum.
But given the choice between enforcing moderation or just letting the personal attacks continue, I'm going to have to reluctantly chose the former.

Dave.

[samgab]

I'm going to have to go with Occam's razor on this one.
There is probably some really complex and elaborate electronic method to do this trick, but it would take about 5 mins with Final Cut Pro to "light up" those LEDs.
If it's not editing, then it may just be lens flare; but there is a bit where the light is in front of his finger:

Dave, any ideas on how this might have been accomplished?

[EEVblog]

Dave, any ideas on how this might have been accomplished?

I just watched it and haven't given it much thought. But obviously:
- The battery can be hacked. Likely a bunch of cells removed and replaced with some circuitry. Even the battery snap could have something in it.
- The LED's could be drilled out and replaced with a tiny SMD led and some circuitry, and then re-potted with leads. Very fiddly, but possible I think.
- The switches are big, probably for a reason. Once again, circuitry internal very likely.

With any or all of those things, pick your method of control...

Dave.

[ejeffrey]

How about this:  You drill the LEDs and put a dallas 1-wire switch like the DS2405 or DS2413, a zener shunt regulator, and an LED.  You wire up as many devices in series as you want with a current limiting resistor.  The battery can be just a battery.  Each switch contains a small microcontroller powered by its own coin cell and a normally closed MOSFET switch shorting the switch terminals.  With a bit more care you could probably have the circuits in the switch powered by the battery, but a small coin cell easily fits and makes things simpler.  Now, when you flip a switch, the microcontroller opens and closes the switch to transmit the 1-wire address of the corresponding LED, causing it to toggle.  You are limited in the number of LEDs only by the available battery voltage.  A 9 V battery should be able to do a chain of 3, but you could easily fit a higher voltage battery in a 9V battery can.  Sounds like a right pain in the ass, but it should be doable.

[EEVblog]

Thread cleaned up with all last comments deleted as a matter of course, I hope everyone understands, and that it never has to happen again.
Kiriakos has been banned, I've had enough pot stirring.
Back to your regular scheduled thread...

Dave.

[ron]

Whew! Back to topic. 
Could this be accomplished if the "battery" is a pink noise source and the switches and LEDs have selective RCL bandpass circuits.   Not an EE, I don't know if the actual miniature components exist. But this is similar to an old problem that we solved with Fourier analysis.  I'm just a retired physicist and I was taught that when you need to design a chicken coup -- assume a chicken is a sphere.  Please take it easy on me if I'm way off base.

This sort of reminds me of the dubious 555 easter egg (EEVblog#160).  Only not as funny. 

[dcel]

I have been to the battery manufactures website and compaired the battery in the video to the battery on the site and they are NOT identical. So, it is entirely probable that the battery in the video has indeed been modified. Now, the question is HOW was it modified? It was also suggested by the videos creator that every item used the make the circuit needs to be considered in the function of the circuit.

Chris

[Short Circuit]

He added at least one AC source. Possibly by taking the battery apart and a small battery + circuit in the case. Or maybe just inside the battery clip. Not much space, but doable. Squeeze better to add two AC sources and you can drive four leds, like my circuit.

[don.r]

Unfortunately, this kind of exercise is not so much of a puzzle as a "what circuits can I squeeze into other components" problem.

This is a good catch and looks suspicious

Just from youtube:

To:AnnoyingVerification (=Short Circuit)

You are the first one, who actually give me one of possible solutions.
My "3 LEDs" is made very close to your design...
I didn't put 4tt LED, because it could be a hint to answer, but 4th LED is not problem to add
Look forward for my next riddle !
