NonSerious Circuit: The series circuit that acts (sort of) parallel.

- A circuit puzzle I built in the early '90s to try to stump my friends. It also challenged a few of my professors too, so that was rewarding!
Feel free to ask questions (yes or no type, preferably).
I tell no lies in the video - everything is as I say. The trick is to discover what I haven't said.

You were all wrong. He is a master magician.
The lights are controlled by strong thought waves that emanate from his brain.
I've heard he can pick up small trucks with just a thought!
Shhh......Don't tell anyone that the trucks are just small toy cars.
You= wicked smaht. Me= look at the pretty lights.
You're right about one thing, the lights are pretty!
Do you have diodes in the circuit?
Yes :) Any guess as to how many and how they are configured?
@@intocoasters I am still trying to figure it out.
There has to be a simple microcontroller in there, right?
There is no microcontroller. Pure analog electronics. Besides - I am rubbish at programming, LOL
@@intocoasters I'm still not sure how it works, as I don't know a lot about electric components. But yesterday I opened up a light I had with a LED strip inside. The strip had warm white and cold white LEDs on it. I am familiar with this knd of strip but wat struck me was that there are only cables coming off. So I started wonderng; how can you control the brightness of both LEDs with just 2 cables. So it might be the same tech that you used to achive this trick.
Please tell us how... this will be a nice puzzle for a electrician friend
Thank you! I will be make an explanation video and a kind of 'how to' soon. And yes, this is a great puzzle for electrician/electronics people!
I don't have a question, I want to puzzle it some more... but I do want to nibble away at this for a bit by starting off with the obvious things... if the circuit were wired as shown you'd always have a series circuit and unable to control the bulbs independently... so power is somehow routed to the sockets independently despite how it looks. Next: I wouldn't take either the switches nor the lamp sockets at face value, they could modified in some way internally to hide a component. Maybe the wire hides some secret... maybe they look like a single wire but maybe they have more than one conductor like a coax. And It is hard to tell if the lightbulbs themselves are modified and then glued back, but I did notice that each time you started the demo you had both switches turned on so that both lamps would light. I wonder if it has to do with sequence of which bulb is put in first or which switch is on... My mind goes to a diode, or capacitor? WOW!!! It's not clear to me how you did that! Hmmmm... More thinking required.
These are AWESOME observations - and I will try to clarify without divulging too much.
The circuit is, in fact, wired in series. I should've pulled out a DMM to demonstrate that. As for not taking the switches or sockets at face value - you are on the right track! However, Half of those are exactly what they seem (but I won't say which half (grin)). The bulbs /look/ normal when inspected but, this is good to doubt their face value as well.
The wire is standard 18AWG lamp cord and is wired as it looks. No trickery or hidden wire paths. This could be confirmed with a DMM tested at all the contact points in whichever combination that could be tested.
The status of the switches at start-up have no bearing on the operation. I did that to show both bulbs have to be installed or neither would light up. I didn't think that it would look like startup process or anything. Good to know that it comes across as a misdirect! I will use that to demo this in person from now on. LOL
You mind is certainly on the right path for additional components!
I will be making another video soon of how it is done with schematic and everything. Maybe even tear it apart and re-build it from scratch for the video.
Thank you for watching!
@@intocoasters Okay that's helpful, it might be enough clues, the switches are where I'd expect to find a cap and a diode... caps will pass AC even if the switch is open and a diode could be used to select the polarity positive is one color and negative the other color... and I think the bulbs also have diodes hidden in them for either to light or extinguish the bulb that is not supposed to light... hmmm.... I know there's something very clever going on! but still not sure how it's done... still puzzling over it.
@@raymitchell9736 You've almost nailed it! Similar to da-Share's comment, You have a couple more components than needed to replicate what I built. But almost perfect! I will be doing a tear-down/rebuild video with schematic soon.
@@intocoasters I have sketched out several schematics and looking at the half-wave rectification as a plausible implementation, but then it looks like if I pass AC through a cap when the switch is open, and a diode when the switch is closed, I think you're also taking advantage of a threshold property of the lamps, I'll bet that in a dark room you'd see the other lamp on dimly... So I have an AA degree in electronics and this stumps me... believe me when I say I'm trying to sort out what you did! I'm waiting for the reveal so I can slap myself on the forehead and say Oh Course! LOL I kind of wish I could figure it out before the reveal to see if I'm right.
@@intocoasters P.S. I think there's 4 diodes and 2 caps... some resistors too?
Hidden diodes?
Yes :) Care to have a guess where, how many, and in what configuration?
@@intocoasters without thinking about it too much, one in each switch and 2 in each lamp?
@@intocoasters I sketched it out with 6 diodes in total and it would replicate what you have.The camera didn't show the half wave flicker due to the filament persistence. :)
@@daShare sooooo close! I mean, extremely close... I'm trying to figure out a hint to help you zero in on the count and configuration. I'm also curious as to what your sketch looks like.
@@intocoasters I can wait until others catch up :)
Man can u please make longer videos it takes u forever to upload then when u do there so short
This is great feedback! I worried my videos were too wordy or overly explaining things. My next video will not be terribly long as it will be an explanation of how this was built. But I will aim for more content and more often.
Thank you!
U make great content man I prefer u to word and talk cause it helps people understand u better plus ur actually teach in ur videos appreciate it I been working on a dark ride for 2 years will be done next season its a massive ride ride vehicle is complete and track and its all because of ur videos
@@massprankstv324 Thanks man, I really appreciate that! I will be doing another video on this NonSerious circuit with a tear-down and rebuild. I'll draw up a schematic as well.
I look forward to seeing your dark ride cart! That sounds awesome!
I have been trying to come up with upgrades or modifications to the carts... any ideas? I do plan on building something similar in the spring/summer that will have videos to go along with the progress.
You begin with switches on. I suspect that's key here. That's all I got so far.
Why have 2 switches on a single circuit? The color is a misdirect.
You gave a big juicy clue at 5:25 then I go blank.
You said "powerstrips" plural. Why would it need more than one. You made a mistake there? IDK. 🤔
The switches on at the beginning are to demonstrate that both bulbs have to be installed before either will light. The 2 switches are to control two different lights - the color can be anything. Just so long as they match the bulbs that have been treated for the circuit. As for 5:25, I don't know why I changed my mind as I was about to swap the bulbs. They can start with both switches off or on or any combination. And this was filmed at my work, so the bench had the power strips - it works the same if plugged into any normally wired house outlet (120VAC as the bulbs and switches are rated for that)
You have made some great observations!
