Allen Bradley PLCs are a notable exception, probably others. The IO cycle runs separate from program so inputs and outputs may change at any point in the cycle

For me it’s the S7 313

> Does that exist? I mean, surely it does, but it doesn't seem like it's common. Is this just industry momentum or am I missing something?
There’s the finder opta, controllino and many like them, usually arduino based. Technically it’s very possible, but factories don’t generally trust those small nee manufacturers for their 24/7 operation Afaik the entire Siemens Logo line is exactly that (MCU with relays and ethernet), you see them sometimes in industrial applications. Also relays outputs are not as important as they once were, you just use bus modules these days. I’ve seen some tracking equipment suppliers that just run all their shit on a PC in NodeRED with Moxa instead of using a PLC. It works too but they need a redundant server configured on-premise for it to work, and after 5 years nobody remembers how it was supposed to be configured
>>
>>2851696
>the entire Siemens Logo line is exactly that
the semens logo is very slow and limited although stm32 based. For example it has an ethernet jack but thats only good for the webserver, as plc slave or for fucking modbus tcp (who uses that shit).
Its entire purpose is its cheaper than 4 dedicated timer relays, but you'd have to be fucked in the head to use this on some production machinery, you dont even know in what order the compiler puts your instruction strings (and it doesn't even matter as the thing has to static memory)
>>

> but you'd have to be fucked in the head to use this on some production machinery
Didn’t mean to imply machinery. I’ve seen them mostly in sanitation equipment (hand washing stations, automated drain flushing etc) and access stuff (automatic barriers, speed doors) in factories, but also sometimes you see a lone conveyor with one

> who uses that shit
Cheap home/small business installations (garages, kitchens, smaller greenhouses). There are a lot of cheap remote IO/relays available for it and it can be used on the existing home network. Also some drives like the Danfoss VLT have an option for it for ‘motion control on a budget’

Can't stand the radio playing at em so I go to Lowes instead.

I want to put together a kit for servicing my car ( low end Toyota corolla). What do I need and what is reasonable for a layman? By layman I mean someone with *zero* knowledge. I have no interest in cars. This is purely for saving money.

I can do do a basic service I'm sure, which would need the below-

- socket set to drain engine oil
- socket adaptor to take off oil filter
- oil pan
- jack
- jack stands
-v wheel chocks/ramps

I know a basic service is doable. What aspects of a a major service could I do? My car has nearly 200k km on it, belts next replacing and all sorts. I'd feel confident doing spark plugs and such, maybe not brakes though.

I've got a headlamp already I'm 99% of the way there. Fortunately I now the exact hsotry of my car, there shouldn't be any dodgy custom mods on it. Always a dealer service.
>>
>>2851225
Sorry to burst your bubble anon, but just because you went to the dealer doesn’t mean everything was done correctly. Juan and Pedro and a case of Tecate will definitely cause a mess, but I have seen the dealers pull a lot of bullshit. Remember that those dudes are normally paid book hours do they’re trying to race through as many jobs as they can in a day. Also shops aren’t always using the best OEM parts, they’re often getting the same stuff from AutoZone that Juan would’ve used, but with a 30% bump in price: Auto techs also generally aren’t the valedictorians of their high school.

Learn how to do the work yourself and you can do better than the dealer techs because you can take your time and do the job with care because you actually give a damn. Plus you can choose to use better qualty parts on many jobs and it will still save you money.

Summing up the advice so far OP:

Get a Haynes manual, or a proper workshop manual if possible for your specific vehicle. You can legitimately not know anything and take your time reading and be able to just about completely rebuild most systems with the tools and a lot of patience.

A basic tool set will be affordable and have most of what you'll need. You will get a ton of little things you don't need most of the time, but you'll thank yourself every time you need just the extension or an odd size socket etc. I would however stress unless you have older American junk stick to metric.

Jack Vs. ramps to me is no brainer, jacks can be used regardless of location and offer the ability to lift a single point. With the MANDATORY JACK STANDS you can use simple wooden blocks to get the whole car up high enough to comfortably work under.

A light is going to be pretty much necessary for someone who doesn't have experience under there, but nothing crazy, a simple headlamp or camping lamp does wonders.

Oil tray, filter wrench, etc. are job specific. Refer to the manual in item one for the tools necessary for any job prior to starting the task. Breaker bars are universally nice to have.

Little things to consider:
Some kind of padding. Kneepads, a foam matt, anything to keep your knees from the cold, hard concrete.

got this Wilcox I arm, the screw in the inclination adjuster has broken, half inside half out, it's a strange type of screw that has a rod passing through it to keep it in place, the screw has snapped but idk how to put a new one in, the rod doesn't appear to be removable.
I could drill it clean, thread it and put a new screw inside, or not thread it and put a stop nut after the hole.
or I could try to glue it but idk if it'll work

I love masks and I'd like to make some myself, but I have no idea where to start, I don't know what material to use (I prefer masks that are not very flexible, so no latex) but it shouldn't cost me too much either, especially as I'm going to make a lot of mistakes at the beginning.

I can't find many resources on the internet in this area, there are a few videos but they often use different techniques and materials, so I'm even more confused.

To start with, I'd go for a very basic shape like pic related and cut out or decorate.

Do you have any advice or resources on mask-making?

Use several layers of heavy aluminum foil and contour it to your face. Carefully apply paper mache strips to the inside and outside in layers, letting each layer dry . Cut eye holes and etc after it is solid enough.
Waterproof glue and lots of layers make them pretty strong.
>>
>>2851067
Once you learn to work with paper mache well you can upgrade to polyester matting and make it as strong as you want. Same principle but the matting is a bit stiffer. If you need it even stronger carbon fiber+epoxy.

I'm remodeling a building on my property to turn it into living quarters for myself. The only hitch is the toilet. I'm not sure if I have enough fall to connect it to the existing septic system, and even if I did, it would be illegal/risky and take a lot of work. What other options are there for me to have an indoor toilet?

why not electrolysis? you dont need to dunk your rusted car into a container. you just wrap the sacrificial metal with a cloth and wet the cloth with the electrolyle and rub on the rusted metal. you can even hardcore cheap it out using steel wool as sacrificial. doneit and works the best, because it turns out the very close surface contact heats up both metals so much you end up blacking the metal, protecting it against future rusts. no other derusting method does this.

ive done it with an 19v dc laptop battery. its pretty easy. you dont even need to have a liquid container to dip it on. just get one terminal on your dry bare piece you wish to coat and the other one on the metal you wish to coat with. wrap it with a cloth or something that can absorb liquid. dip the cloth on the electrolyle and scrub the piece you wish to coat with. ive done alot of derusting with this technique, its really good for large surfaces you cant simply dunk on electrolyte.

Do I diy it or buy one pre-made?

>>
>>2849895
Not all frames suit container corrugations (for side doors) or blank ends or end doors but an angle frame is a breeze to weld.

I support the door horizontally and level, then use welding stands to support the frame. I shim the door clearance between the door and frame so zero risk of fucking that up.

Use quality sealant. The HV version doesn't sag and of course it's UV resistant. I just sealed some door trim and end vertical gaps between my side-by-side welded container shop with it.
