this is what it takes to control traffic lights
>>110089277You can tell it's new because it's not filled with ants and/or wasps
>>110089318its been there for at least a yeari'm sure that happens to all these eventually
>>110089277i like that shit like this has to be reliable.But it's crazy how much they charge for these industrial computers that usually have a CPU from last decade or even older.Not sure what's so expensive about putting them into a different case and maybe designing a different motherboard. Probably the low demand, now that i think about it
>>110089277HOly shit. At the second look I see the relays now. They must make a fucking comfy click. Holy fuck. I wish I had one and could make it click all day
>>110089277you could replace half of this overpriced shit with a few arduinos
Imagine the chaos you could cause by screwing with these lol
Could replace it all with an Arduino
>>110089277I use Arch btw
>>110089405>>110089435You could, but that always has a trade-off. There is a reason this shit is expensive as hell
>>110089465I imagine a lot of it is multiple layers of failsafe/redundancy/etcsince if something fucks up and two directions are green someone could dieas well as the cost of "company b is certifying this equipment so if a failure causes injury they're liable"
>>110089277Sure you could run the whole light timing system off a small PC and control the relays that way but it wouldn't be reliable like these are. I bet those relays make a fantastic click when they actuate.
>>110089486Yes exactly.For most traffic lights this is probably useless tho, I agree.traffic lights might be a bad example. HERE IN GERMANY, we have signs on every traffic lights so everyone knows what to do when they fuck up.But for other industrial automation where it feels trivial, it's actually not and humans can die if something goes wrong. You really don't ever want a human to die, because ded humans are expensive af
>>110089277Cool, now tell me how to program those roadside signs.
>>110089535I wonder if they've been locked down more in the decade since that was popular on /b/
>>110089535I can't find the image but I think it said the code is usually 000000
>>110089392>But it's crazy how much they charge for these industrial computers that usually have a CPU from last decade or even olderCool it with the antisemitism
>>110089392they don't use consumer CPUsindustrial CPUs are built to withstand a much wider temperature range
>>110089513>HERE IN GERMANY, we have signs on every traffic lights so everyone knows what to do when they fuck up.Never change kraut frens, never change
>>110089631This is all bollocks, I rember when they were sticking z80s in the nose cones of supersonic jets.
>>110089513>>110089639"Wenn man es konstruiert, kann man es auch gleich richtig kompliziert machen."
>>110089651z80s with a range of -40 to 70°C
>>110089639that's a compliment, I guess. Thank you!
>>110089277while(true){sleep(60)light_on(green)light_off(red)}they should've hire me
>>110089841Make sure to write all embedded soft with python 3.15. You're the best.
>>110089513silly turk
>>110089513time to deport a bunch of those things that are there.... you know what ones
>>110089318
this doesnt surprise anyone that has actually made anything in the real world. plcs work because theyre dumb as fuck. cabinets work because theyre big and made of steel and you can lock them. doesnt change that theyre all networked and rely on a server thats running software that reads sensors like inductive loops under the pavement to count cars. the smarts are still dont on actual computers, but the hardware parts are still 12/24/48/120v sensors and lights and relays and shit.
>>110089398relays are fucking expensive for some reason??? i bought some for a project recently and it made me mad as fuck that i spent that much on them, but i do love the noises they make.
>>110089277
>>110089926>>110089979that's all just media propaganda. It's really not that bad.You got the same small problems as in other countries, but there is more important shit than a few hot black girls
>>110089613
>>110089513>because ded humans are expensive afNah, dead humans are profitable as fuck. Once we die suddenly we pass a lifetime of wealth onto our family. It's living humans that are expensive, especially when we get old and sick or are non-white.The renaissance happened right after the black death after all. If you want another renaissance start killing people, especially if they're old or brown.
novax status?
>>110090331they are expensive af for the companies tho, if they got no good insurance.But even if the insurance is good, then they have to pay more for it afterwards.ded people are good for personal use, yes
>>110090331Uhhh you really think that when all countries are trillions in debt you're gonna pass on any wealth? The only thing gettinh passed on is debt.
>>110089631The real reason is that they need certification, and all those lazy government entities you have to deal with, to get that, aren't cheap.
>>110089277I feel like this could be greatly simplified. Why couldn't it just be a few Raspberry Pi's (with the extras entirely being for redundancy) You just connect it to the sensors in the road that detect cars and have it cycle through the traffic light phases accordingly.
>>110089631>>110090349Also it's the same point with 'just build it in arduino'Probably even more. They most likely just could use normal consumer CPUs. I mean Hetzner does this on an incredible big scale. Tho Hetzner is in a protected environment. So there might still be some very very rare edge cases. And to get the certification for 5 million trillion bucks from the government, you gotta eliminate those edge cases - or minimize them. Eliminating is impossible and just exists in government brain
