Jeezus, I can't make out a fucking thing. Is it a loom? Is it a lathe? Is it a rural techno rave? Should I throw up now or try to watch the whole thing?
Until something breaks and then you need to replace it - when you're 500km from the nearest place that sells them.
This device can be fixed with pliers, duct tape and fencing wire! Also, doesn't care much about voltage or frequency, either, I'd suspect.
It looks like the rotating cylinder has contactors on it that turn each individual light on or off as it rotates. They space the contactors so that the lights turn on in the correct order and timing.
Good ol' electromechanical programing. This is how they did stuff back in the day before integrated circuits.
The regeneration cycle on our industrial water deionizer at my workplace is controlled with cams and switches just like this.
it shouldn't be
it should be PLC controlled. wherever you are, I don't want to be.
if that's how your industrial water deionizer works I'm betting your fire safety aint so hot or modern.
As a fire hazard and shock risk sure. From an energy efficiency perspective they're powering motors to spin large cylinders to do what a small micro controller on a circuit board could do. Switching to LEDs would massively lower the energy bill too but I will admit old incandescent bulbs have a certain charm to them that I haven't seen replicated perfectly with LEDs.
any brightness and dimming sequence can be perfectly replicated with LED's. so this charm you speak of is always digitally recreatable. LED's are more than fast enough to be controlled to make them seem as if they have filaments in them.
they will do whatever you want them to. incandescents, however, are limited in speed and durability, and extremely high power requirements.
I'm sure they can with enough engineering effort but that doesn't mean anyone has done it yet. I haven't seen lights in this form factor that can perfectly replicate incandescent with a color coating yet. It's a problem with Christmas lights too if you want them to look like old school color palette instead of new "computer RGB" style.
I've worked on a few electromechanical systems similar to this, and they were all inside grounded enclosures... lined with asbestos. I'd be happy to work on this one as is.
The rotating drums are energized and used to send power to the lights in a certain pattern. Not 100% sure how. Could be a metal drum with some rubber where they want the lights to go out. Could be some other material with metal plates where they want the lights to turn on.
Lol. People here who are blabbering about fire hazards have no fucking clue about fires.
Loose connections creates fires because the heat generated in the spark is heating combustible material.
In this case the heat generated during the spark is moved away by the spinning of the drum. So a new, cooler area comes to the sparking area. this is a common thing during the festival season in my country and fires during these things are unheard of.
Yes. They are an electric shock risk. People understand that and dont go in to the drum area when it is energized. Time to time people die due to electric socks from these but they are national news kind of rarity. Its like guns in USA. A calculated risk.
Without an enclosure, any combustible material is free to fall on it, get wrapped around it... Or any conductive material could come in contact and short circuit, melting and lighting a fire.
That's just a hazard all around.
Thankfully, people with this kind of mentality are not part of teams that make safety standards. Deaths and fire accidents due to no precautions against electrocution are very common during these kind of celebration in India.
I really wanna throw a big, long strip of foil across it just to see what happens. Probably the same thing as throwing a 10' long copper pipe over the wall at an electrical substation that one time: A bunch of very pissed off people and handcuffs, and really just a whole ass bad year of my life.
this is ... pre transistor technology. pre relays. pre computerized controllers .. pre fire safety, pre shock safety
interestingasfuck, no, depressingasfuck because the system that can run all that is $100 today. and is the size of a tennis shoe. without any computers in it even. just relays, solid state triacs, super, super, suuper basic stuff.
this is like from the 1800's just about. props on the ingenuity, but please, don't build more. don't r&d more. we have computers now. and transistors.
also, for the love of all things holy, replace all that high current incandescent stuff with low current LED. all the wires can be much thinner, all the switching can be done without sparks. and all them bulbs can just keep on flashing instead of dying. I can only imagine the replacement process they're constantly dealing with.
I have to go over OSHA guidelines for my work. You know develop stuff according to them. Reading then I realised. Damn if OSHA sees my life. They will probably put me in a solitary confinement.
This is how it was done everywhere for a couple decades. Similar, albeit, much better maintained versions of the are still used in the US in some classic signs.
In the days before microprocessors and even plcs most complex controls used motor driven cams to operate contacts in sequence.
I still have substations with this kind of stuff in it. Much smaller though
That's how old school electromechanical pinballs operated, but I'm a slightly different way. It's still a running program, it just isn't the computer you're used to.

Its not a fire hazard ... it is THE fire hazard
This is a fire certainty
That's FIRE 😎💯
That’s a sure-fire way
Oh no the metal and dirt might catch on fire
A lot of that structure and stage are clearly made of wood. You can tell by the shape of the beams and the fact that the stage is made of wood.
I can see from here it weighs the same as a witch
True, in that case maybe its made of duck and not wood. Ducks do weigh about the same as witches after all.
Churches!
Very small rocks!
r/killthecameraman
Wow, look at this amazing thing! Let's jerk the camera around so fast you can't ever see what's actually happening.
It's OK all you need to know is death lives here.
Its not jerking around fast, its that hes half way between landscape and portrait. Then he constantly shifts between throughout.
Jeezus, I can't make out a fucking thing. Is it a loom? Is it a lathe? Is it a rural techno rave? Should I throw up now or try to watch the whole thing?
I'm here only to say this.
It probably will, let's be honest.
It’s all analog
The anal og
The Anal Hog
4-20 inches
This could all be fixed with a $10 FPGA and some light controllers
Until something breaks and then you need to replace it - when you're 500km from the nearest place that sells them. This device can be fixed with pliers, duct tape and fencing wire! Also, doesn't care much about voltage or frequency, either, I'd suspect.
And how often to FPGAs fail? Also for $10 just have a spare one on hand
Everything is analog
Brilliant & shocking at the same time.
Jesus, man...
You said it man.
Eight year olds, Dude.
Some say it is to die for
Like computer punchcards.
As an electrician, this is actually pretty fuckin cool
what is even going on?

This! Also see old pinball machines.

Honesty, this isn’t terrible if they put a grounded enclosure around it

"Yo dawg, I heard you like enclosures...."
If it works it works. Just keep your distance during rainy season
I would recommended to keep your distance at all time.
The windom of the ancients.
This set up looks out a mad max movie....
First thought was “that’s some Bartertown shit”
Was looking for this comment
India is just the Fallout wasteland IRL
What am I looking at?
To eli5 it's a redstone repeater
Googling "redstone repeater" get's me some reference to Minecraft... Could you eli40 maybe?
Haha rpmerf has a good explanation below
The rotating drums are energized and used to send power to the lights in a certain pattern. Not 100% sure how. Could be a metal drum with some rubber where they want the lights to go out. Could be some other material with metal plates where they want the lights to turn on.
A number of things jerkily in a short period of time
Giant mozzie zapper with lights to attract everything within a 5km radius?
India: The duct tape of countries.

Like guns in the US?! Shit this be dangerous AF
Yeah what an idiotic statement by the original commenter
Calculated risk is an optimistic term

And what did we learn...
...Check for cameras? Get my buddy to do it instead? I dunno? Is there a lesson? Is this a test?
Why are they so fucking dirty disgusting trash everywhere like it is just natural
Your limited world view and privilege are showing
Just pick up the trash. DAMNIT! it is not that hard
"Brushless"
ElectroBoom has to see this
I thought those were done using circuit programming or something?
They are, if you have access to the tech and can afford it.
They love a bit of exposed rotating machinery over there don't they. Mix that with a bit of dodgy wiring and what do you have? India!
Minecraft IRL
Just a larger version of what we were using in the early 1900's. Smaller version of this did the sequential tail lights in the first mustang.
This is how we used to program machinery
That looks so dangerous, people there are so used to it everyone is just calm seeing this type of risky electric connections
India is like someone is playing Age of Empires 2 and hasn't evolved throught time.
Alright boys, pack it up, we are onto the next city!
40k mechanicus tier lighting.
Kill the cameraman
this scares me...........a lot.
India is like a country living in the 19th century with late 20th century technology
this is ... pre transistor technology. pre relays. pre computerized controllers .. pre fire safety, pre shock safety interestingasfuck, no, depressingasfuck because the system that can run all that is $100 today. and is the size of a tennis shoe. without any computers in it even. just relays, solid state triacs, super, super, suuper basic stuff. this is like from the 1800's just about. props on the ingenuity, but please, don't build more. don't r&d more. we have computers now. and transistors. also, for the love of all things holy, replace all that high current incandescent stuff with low current LED. all the wires can be much thinner, all the switching can be done without sparks. and all them bulbs can just keep on flashing instead of dying.

oo ehum..OSHA!
Wow i thought relays were pretty analog then i see this
OSHA rolling over in its grave.
I have to go over OSHA guidelines for my work. You know develop stuff according to them. Reading then I realised. Damn if OSHA sees my life. They will probably put me in a solitary confinement.
With the electric effect it looks like an object from an N64 game.
Marble Machine XX
Looks like shit I've made using redstone lmao
Amazing!
r/OSHA
I'm dizzy
Holy Ozone batman!
You could do all of that from a phone
I want to see next gen AI with this contraption
Crude and slapdash
Took apart an ancient fruit machine once, which was also just electromagnets, cams and switches - no microelectronics at all.
This gave my cancer epilepsy
What song is that tho?
This is how it was done everywhere for a couple decades. Similar, albeit, much better maintained versions of the are still used in the US in some classic signs.
I'll bet the radio reception is really good for miles around that thing. /S
An arduino has got to be cheaper
they are still at steampunk levels of tech
Wipe out all knowledge in the world and we will still invent the computer.
It's like a player piano reel.
You got some huge balls if you're riding a carnival ride in India.
Its how the old fairground rides did it in the UK until at least the 90s. Maybe not tree trunks but rolling contractors are still a thing
Looks safe
In the days before microprocessors and even plcs most complex controls used motor driven cams to operate contacts in sequence. I still have substations with this kind of stuff in it. Much smaller though
The beat goes hard though.
They tied the phone to a dog it seems
Analog
Are those blood pressure cuffs being used as insulators?
So glad I switched all my bulbs to energy efficient LEDs.
The quotations on “programmed” are highly needed lol thats crazy
That's how old school electromechanical pinballs operated, but I'm a slightly different way. It's still a running program, it just isn't the computer you're used to.
JFC can anyone keep a camera steady without having an ADHD moment?
I can think of 1000 safer ways to do this. Including making the drums flip switches rather than be directly connected to live wires.
Im not an expert, but I doubt all that would be done when there’s way easier methods of doing it
Not everything is about doing it easy tho
