There's an nice anecdote from James Gleick's book _The_Information_ about Claude Shannon making a telegraph on a barbwire fence:
> "A curious child in a country town in the 1920s might naturally form an interest in the sending of messages along wires, as Claud Shannon did in Gaylord, Michigan. He saw wires every day, fencing the pastures--double strands of steel, twisted and barbed, structed from post to post. He scrounged what parts he could and jerry-rigged his own barbed-wire telegraph, tapping messages to another boy a half mile away. He used the code devised by Samuel F.B. Mores. That suited him. He like the very idea of codes--not just secret codes, but codes in the more general sense, words or symbols standing in for other words or symbols. He was an inventive and playful spirit. The child stayed with the man. All his life, he played games and invented games. He was a gadgeteer. The grown-up Shannon juggled and devised theories about juggling. When researchers at the Massachusetts Institute of Technology or Bell Laboratories had to leap aside to let a unicycle pass, that was Shannon. He had more than his share of playfulness, and as a child he had a large portion of loneness, too, which along with his tinkerer's ingenuity helped motivate his barbed-wire telegraph."

Sears was the Amazon of the day. Order by mail, receive by rail shipment, completely bypass local retail infrastructure. In some case this meant unmarked crates to avoid trouble.
Here's a link to a catalogue page for DIY telephone equipment from those days. At least the link works for me right now.
That whole catalog is incredible, like a time machine.
I remember looking in awe at the Sears catalog every time one came by mail, then all the smaller specialty ones.
I get similar feelings looking back at heathkit catalogs from 1950s, 1960s, then there are the Radio Shack catalogs when the TRS-80 first came out, the world seemed like it was going to be amazing...
How about McMaster-Carr? Their catalogue, print and online, seems to have a very similar philosophy. Also: all but the most specialized items get same- or next-day shipping.
I have to say that I don't really miss the McMaster-Carr catalog. Back when calling them on the phone was the only way to order, getting a catalog out of them was like pulling teeth. Things are far better now with online ordering: they'll sell to anyone.
I may actually still have a Small Parts catalog around here somewhere from before they were swallowed up by Amazon. The last time I ordered from them the box said Amazon Supply and I knew the end was near.
Is it really surprising that ADSL2, which was apparently designed to work "up to 5000 meters" of copper, can work over 2 meters of wet string? Wet salty string being 1/2500th as conductive as copper wire doesn't seem too far fetched.
On the first one, yeah, TI's got chips (so do a few other vendors), but I'm not competent at designing (or building) ethernet circuits, so I need someone else to put a 10Base-T1L PHY back to back with a 10Base-T PHY, and do those other things.
Pace1KL looks interesting, but the price (seems to be $129 each) is too high for me, especially since I'd need to supply PoE on both sides. In an ideal world, I'd get one unit which was powered and was a PSE (power sourcing equipment), and the other unit was a PD (powered device), so I didn't need to find a safe place to tap power where my line ends. Of course, in an even more ideal world, I'd have two pairs so I could run standard ethernet :)
Barbed wire might be a great invention but my personal experiences with it are not so rosy.
I was cleaning up my property and found some laying on he ground from where there once stood long rotten fence posts that had since decomposed completely.
While cleaning it up by wrapping it around a piece of wood, I learned the hard way that safety glasses are essential when working with it...An end of a strand in an almost lifelike manner whipped up and slashed me across the the bridge of my nose and my right eye lid.
That was but one experience, since that time I have had the pleasure of laying under my backhoe with bolt cutters to remove 100s of feet that ended up wrapped around the front axels and walking through puddles in my gum boots only to realize the dreaded stuff had struck again by putting invisible holes in the bottoms of them.
I believe I have managed to collect the majority of the abandoned wire but now I face the dilemma of what to do with it. I don't want to take it to the land fill and make it someone else's problem but don't want to have it in my way either as it is very heavy and cumbersome to move.
My only idea is to get a forge or smelter and transform it into a less menacing product.
Scrap yards don't want to deal with a tangled mess of barb wire - some won't accept it at all, some pay an extremely low rate for it. But if you cut it into short pieces (3ft or so) and neatly bundle it, most scrap yards will happily take it at their regular scrap steel rate.
Yeah barbed wire is tricky. I grew up on a farm and built a lot of barbed-wire fence. With the right PPE (mostly boots and good gloves) and tools (fence pliers [0], comealongs [1], etc.) it gets easier. Plus when you're building fence the wire comes on a roll which is much easier to manage than random barbed wire lying on the ground in a pile.
Shred it. That will allow you to get the regular price for rusty steel for it.
You may be able to rent a shredder or you may have to pay someone who has one to shred it for you. In the past barbed wire was a problem for shredders but the latest models eat it up like so much candy.
Yuck, I know the feeling - just for me it was a piece of lightning rod conductor that snapped out of its coil, still have the scar in my face, but it has faded thankfully. Hope you did recover from your injury!

Sell it at a scrap yard. They will sell it to a smelter and that's it.

If you go that far in yak-shaving, there are some pretty amazing how-to videos on Youtube that detail how to build a proper forge - and actually make an axe or other medieval weapon out of ore.
I wonder if you can do an interesting Damascus with it like those guys who do the same with old chainsaw chains.
In landfill it's a waste of embedded energy but not likely to be a hazard so I wouldn't worry too much, but clearly made something cool >> efficiently recycled >> just junked.
The National Cowboy & Western Heritage Museum in Oklahoma City has a fantastic collection of barbed wire strands- well over a thousand different styles. I can't remember if it goes very deep into the fences serving as telephone networks, but seeing the variety of types and their evolution into a wire that could be cheaply mass-produced is fascinating and impressive.
My dad worked for the phone company his entire life. He told me that early in his career, in the early 1960s, he did the engineering to convert a lot of barb wire circuits to central office circuits. He also said the used to have huge bonfires to get rid of the old wooden crank phones. This was all in Southern Illinois, not the Wild West.
My first job out of school (in the '80's) was working for a company that managed the infrastructure for state lotteries. We ran the Texas lottery and, yes, we did occasionally have point of sale terminals drop off the network when a rancher forgot to close a gate.
Is there any more details somewhere on how this worked? I assume they required electricity but where did the electricity come from? Was it using same exact phone they had in cities at the time? Not even sure what connections were required for regular phones at that time either. Any info would be helpful for my curiosity.
The old style phones used a local battery to power the carbon microphone (usually a pair of No.6 dry cells), and a hand-cranked magneto to generate the ring current. It's only relatively recently that city phones used a "Central Battery".
This reminds me of a story about someone running a LAN from their house to a shed via a barbed wire fence. Apparently they got a fairly good data rate except when it was raining or a cow was leaning against the fence.

Copyright infringement. But nobody cared. That was the beauty of the Internet last century. The general public wasn't online (much), the impact of what happened on the Internet was limited. Even though 1on1 could be eavesdropped (like physical), nobody cares. Usually. And if they do, they will eavesdrop, that is still true nowadays (que NSO zero day reference), and probably justified (has to be within proportion of law).
I remember reading a brief note about some people somewhere in Africa running and X.25 network over barbed wire, and it’s been something I’ve wanted to try since.
That article references another one (that now 404s but is in web archive). Amazing story that mentions how people hooked up these systems to the normal one.
Why does this keep popping up on the dash here? I have seen it at least three times in the last few months. It is an interesting historical factoid, but there are plenty of others now more worthy of my attention.
What this highlights for me was the loneliness of the homestead-era West, and the many attempts by people to connect with each other across the empty acres.
It is an under-appreciated fact in America, and generally obscured by the Marlboro cowboy LARPing among certain cultural factions, that those who settled the West itself tried very hard to congregate, communicate and help each other in the face of harsh conditions. The loners didn't make it; the cowboys themselves were usually the hired help.
Settlements in the west tended to congregate more densely, when they could, than what you see in rural New England. I believe this is partially because much of the west is a desert or semi-arid desert, and communities formed near the scarce sources of water; whereas the northeast didn't face those constraints.
The west was already settled. The "settlers" weren't interested in befriending or communicating with the indigenous population. In fact they were down right hostile towards them.
That wasn't the point of my comment. North America has been settled and re-settled for thousands of years, much like Europe, the Middle East and most of Asia. It's called immigration. It's happening in North America even as we speak by people who are not "from here." Who cares? There are no natives. Just a bunch of people who need to learn to live with each other.
Of course, the Americas were quite densely settled before their first contact with Europeans. By the 15th century, they had produced civilizations, notably those we know as the Aztecs, that were arguably more advanced than any of their contemporaries.
But the Aztecs, the Incas, the Mound People of the Mississippi Valley and the various warring tribes of New England were all decimated by diseases that the Spaniards brought with them unwittingly. Small pox and other diseases wiped them out as part of the Columbian Exchange.
While the Europeans did all the usual things that conquering peoples do, they cannot be blamed for that, because the disease ran ahead of them by decades and wiped out tribes that had never seen a white man. They had no idea how diseases propagated themselves, and fell equal victim to some of them (yellow fever, malaria).
If you want to reflect on what actually happened in the European settlement of the Americas, read 1491 and 1493.
And then maybe we can talk about what it was like to be a homesteader in the late 19th century.
You're right, that one nameless group you made up has no more reason to complain any more about the settlers than they have to complain about that other nameless group you made up.
"What's the big deal about me hitting you? I'm sure you've been bitten by a dog before, and I never heard you complain."
You don’t need a city to consider it a settlement, they had dominion over the outlined land, treaties, and trade. I’d consider that civilation, settling, and land management.
The anthropologists among us would also say yes. The alternative worldview that some peoples are civilized (thinking, organized, philosophical) and others are barbaric (violent, disorganized, brutal, militant, uncaring) is reductive and obsolete. If "civilized" is to mean anything, it refers to populations that can form the large permanent population centres we call cities.
What we call cities are vastly beyond the scale of most civilizations with writing, philosophy, etc. As recently as 1500 all it took was 5,000+ people to be considered a city in Europe.
Many Native American tribes reached that standard before Europeans first reached America. They where considered barbarians simply on religious grounds.
I used the barbed wire fence of the horse-ranch I was on, out in the bush, as an antenna for a broken TV I'd found ditched on the side of the road a few days prior .. I got through the static and tuned into RAGE, Cabaret Voltaire Sensoria, and was baptised in electrons for life ..
