The cheapest way to get cables is to know somebody who crimps it themselves, but for the majority of people probably buy from shitty places like walmart for a 1,000% upcharge.

[-] woodenskewer@lemmy.world 35 points 1 year ago

just a heads up for anyone deciding to make their own cables, make sure you buy pass through rj45 ends or it becomes substantially more annoying to make a successful crimp. with pass through you can prep your cable and it doesn't matter how long you make the strands you're working with because you cut the excess off, with non-pass through you have to cut them to a specific size and if it's too long when they bottom out, your conductors will stick out making your crimp weaker inviting poor connection issues later in the cable's life.

thank you for tuning in for this controls tech tip

[-] w2tpmf@lemmy.world 14 points 1 year ago

I like the ones that have a separate little sleeve with a pass though. You put the wires through it, clip them, then insert it as a unit into the connector.

Like these.

[-] ahal@lemmy.ca 3 points 1 year ago

Those are the way.

I bought a bulk bag of the shitty kind. Worst purchase of my life. I was too stubborn to throw them out and it took a decade+ to get through them all.

Didn't know this was a thing. Tytyty

[-] uis@lemmy.world 11 points 1 year ago

Crimper costs you about 2$, rj45 connectors cost 0.05$ and cable costs 0.1$/meter. Not that much.

Alright but I'm storing enough tools and large coils of various cable/wire at my home so I'm going to pass until I move into a bigger place. I don't even work in IT so I'd probably snip one segment and have the rest laying around forever. Still cheaper than buying finished cables at the store, though, I give you that.

[-] MystikIncarnate@lemmy.ca 1 points 1 year ago

You can hire low voltage writing contractors to do it, they usually charge per run (up to a certain length), and they only leave you with what you will use. They're a bit more costly, since you're paying for their time, but it will save you the hassle of buying tools, learning how to use them, buying cable, running the line, doing the crimping (usually several times as you will probably mess up at least a few), and everything.

Saves a bunch of headaches... just an option I'll throw out there.

Don't hire an electrician for the work, most don't understand the requirements of low voltage or ethernet, they're simply not trained for it. They can wire up your fridge or whatever perfectly great, but the rules that apply to high voltage are very different than what is needed for low voltage... specifically Ethernet.

Crimper costs you about 2$

Pffft flathead screwdriver.

...no seriously if you want to buy a crimper spend 10 bucks upwards or so, people have spent more on screwdrivers. A knipex one costs about 30 bucks, we're not talking fibre splicers here. Regarding outlets, those 10 buck LSA Plus things are perfectly fine. Finagling those things with a flathead is way harder if you want more than an electrical connection but actual signal quality.

We live in different economies

380₽ right now, about 3.8$

It's not that you can't get crimpers that cheap here (cheapest I found on Amazon is 3.50 Euros, incl. 19% VAT) it's that they're almost guaranteed to be made from chinesium with the engineering and manufacturing precision to match. There's a difference between inexpensive and cheap.

[-] UnderpantsWeevil@lemmy.world 7 points 1 year ago

For me, its more running lines through the walls of my old house.

[-] doctorcrimson@lemmy.today 2 points 1 year ago

Depending on local building codes, you can run them through vents so long as they're fireproof coated, but TBH that's pretty silly.

[-] MystikIncarnate@lemmy.ca 2 points 1 year ago

I'll just say: attic. That's all.

[-] UnderpantsWeevil@lemmy.world 1 points 1 year ago

Going to be tricky dropping cables from the attic of my three story house into my first-floor home office.

[-] MystikIncarnate@lemmy.ca 1 points 1 year ago

Up from the basement?

If it's an unfinished basement, easy. If it's finished, that feels bad man.

[-] stardreamer@lemmy.blahaj.zone 4 points 1 year ago* (last edited 1 year ago)

Pretty sure the biggest cost of crimping your own cables is finding a place to store the remaining spool.

Or ensuring the spool is still useful 15 years later while everything has migrated to SFP/QSFP

[-] dufkm@lemmy.world 1 points 1 year ago

Nah, the remaining spool will be useful for the rest of its/your lifetime, it always comes in handy as a generic 4-pair twisted pair signal cable for any non-ethernet purpose. I've used my old spool twice this year; first for an m-bus cable to my power meter and then for a limit switch for my garage door.

[-] CancerMancer@sh.itjust.works 3 points 1 year ago

That's me lol. I'm still sitting on my spool of Cat6 I bought a few years ago. At pre-COVID prices it was approximately (CAD) $1 per termination, and $1 per 6 feet of cable.

Today at Infinite Cables and other Canadian stores I can buy premade lengths at almost those costs, shockingly. Prices really came down.
