Where do I get old style wire wrapping pins? sockets? heard about it from Curiousmarc's AGC restoration videos few months ago and I'm hooked.

I've already tracked down the tools, wire, and some perfboard. aiming to work my way up to building stuff with ICs, MCs, FGPAs and the likes

As of a year or two ago Digi-Key still sold wire wrap IC sockets, still may.

I see your DIP sockets, but I'm looking for standalone pins like this, preferably a gold plated variant or something not corroded to shit from age

have you tried pogo pins?
I know they aren't exactly what you're looking for but with some modification they might be good enough
at least they are dirt cheap and readily available in many different variations

you completely missed the point: you google the thing you're looking for. so if you want pins, you google ''WW pins''. if you're looking for bonsai you google ''bonsai''

>doesnt help with sourcing actuall sellers

that's what the ALL tab, and SHOPPING tabs are for.

Not sure if they'd be the right diameter or not but you might try stud welder pins for body work. They look similar and are copper plated so they shouldn't rust for a while. Cheap too. Apparently 2mm diameter according to this link.

I suppose you're being serious, but wire wrap pins have a specific shape that has sharp corners that bite into the wire that creates some sort of magical "gas-tight" connection that won't work with round pins.

>> No.1740131

>>1739966
I guess I should have been more clear, I spent two hours last night trying to source the pins by themselves, wire swappable dip connectors seem to be hit or miss, breakaway ones are prefeeable but I can seem to find many varieties that would be suitable or arent $20-30 per socket

I found some old pins on ebay but they seem corroded to shit and the seller isn't selling their gold pins

>>1739955
wire wrapping pins should have square posts but if they make pogo pins like that you might be onto something here

mouser, ~20 cents a pin, gold pins have 3 week lead time, minimum order 1000.
but why gold plated? are you wrapping with gold wire? do you just hate money

look up header pins. square variety. often come mounted in strips.
i work in a factory that does a metric fuckton of wire wrapping. sometimes we wrap directly to the component, which usually come with pins made for wire wrapping. but you can just make them from any metal offcuts that will fit in your wire wrap tool.
>>1739955
no no no no no, you want the RECEPTACLES for pogo pins. not the pins themselves, the "pogo pins" are interchangeable probes. no direct connection is ever made to the probe.
funny you should mention this, by sheer coincidence, it's what we work with and wire wrap to in the above mentioned factory i work in.

Yeah apparently I know nothing about what the hell you're talking about I thought the pins were just to route the wires to where they needed to go and then you could bundle the wires. Off to google wire wrapping I guess!

I'm gonna tell you something you won't like. Wire wrapping is shit, and it's not popular for a reason. Only use wire wrap if your project doesn't move, and you only want it to last a month or so. It is less than semi permanent. Only use it for testing or quick use builds.. I did it for years and everything I made stopped working because of loose wires in less than a year.

You were doing something wrong or your environment must have been hellish, because proper wire wrapping is very reliable. I've had circuits run for years in fairly bad environments, like a well shed with an open barrel of chlorine.

This backplane is from the 70s and is still in service.

You could also easily apply solder after wrapping

>> No.1740980

What's the advantage of wire wrap over protoboard? What's the advantage over soldering on prototype PCBs?

>> No.1740986

>>1740980
You dont need to solder. You can route the wires over each other and route multiple wires to the same.point. like you could have a v+ pin and wrap three wires on the post.

You could use up to 22g wire easily.

>it's not popular for a reason. Only use wire wrap if your project doesn't move,
define move.
if you mean the wire itself moves, then you should be using stranded core, which is not suitable for wire wrapping. solid core wire always breaks if it is moving a lot. stranded core won't stay wrapped if you move it even slightly, i wouldn't even expect it to stay wrapped after shipping.
the machines i build are in use for over 10 years regularly, they have wire wrapping ON moving parts, those last, but those wires themselves do not move. the wires that move are all stranded core ribbon cables with connectors or some kind of specialty wire which will survive moving for days on end for years.

yeah no solder is the biggest advantage.
it's cheaper and faster than soldering, problems can be more easily rectified than a soldered joint, no power needed for a manual wire wrap tool, you can also get into smaller spaces more easily without damaging surrounding wires than you can with a soldering iron.

sounds like you really suck at soldering and/or don't have a half decent iron

>> No.1742503

>>1741007
Cheaper and faster, I have some serious doubts about that assertion. Soldering takes less than 10 seconds per pin and you don't have to buy that much cable. Also you will have to stick with the largest parts, in addition some IC are only available in SMD packages.

Now if you are pleased with wire wrapping, why not.

>> No.1743901

Wtf is this prototype you're making OP? Seems it would be easier to just etch your own PCB, that is what I've always done, wire wrapping every part of the circuit is just a PITA.

you can have infinite layers with WW, so expensive 7-layer PCBs arent needed. it also means you can make it as compact as the chips will allow. virtually no space is required by wires coz they can flow between the pins and run atop each other.

try designing a PCB for pic related.
