CHRISTMAS OPEN DAYS AFTER MUSEUM REFURBISH :-
Friday 22nd December 2023 5PM-8PM Christmas open evening, come have a look around while the organ plays christmas songs.
Friday 29th December 2023 1PM-4PM
Saturday 30th December 2023 1PM-4PM
Regarding displays, the ringer is behind a barrfier hence its just tacked in with velcro, a handful of other displays are just held on with velcro that need to be entered quite regularly, but most of them, especially ones with any sort of item that is on is screwed shut.
yes kids, this is what it took to log into myspace in 2002
This was entirely obsolete 9 years before that lol...
@@seamusellis1450 i figured, was just making a funny. ♥
I wish I could have experienced a set up like this back in the days when it was in use and busy. The mechanical noise would be awesome!
Just wanted to say, i REALLY like the telephone exchange content, and anything telecom based. I'm a network engineer by trade, with an interest all in all things related to communication technologies, and I think the youtube algorithm recommended you to me a few years ago because of that. Now I'm in to modular synth and have 10 kosmo modules running in my setup! For real, i thought electronics in general would be too hard for me, but you convinced me to not be too scared to try it ❤
nice one!!! good to know :D
It always baffled me how it could work but now you have explained it, it sounds so simple.
It's cool ent it! Simple but complicated ha
soz for the over exposure on this one. my baddd
You need to get some color.... you're looking a bit pale.
Nice job! You'd make Sarah Autumn proud.
I have some strowger gear if you want it, no cost just want a good home for it
we would never say no to supplies!!! it may even be what we are on the hunt for!!! if you'd like fire us an email museum at thismuseumisnotobsolete dot com
When the crowd say “Group Seleeeecta”
Haha
you know what I would love to see? a 56k modem that people could dial into and access something cool like a webcam, with a 30 second drop off timer. But I guess with a telephone you can only have 1 incoming call at a time?
It's looking great. I still have a recording of my call to the original setup from my rotary dial phone (mustard colour 😀) and I remember getting through to you and hearing about my cars extended warrenty 🤣. I love all this work you are doing to preserve an old telephone switch as I've been able to experience it as my dad remembers it.
Nice one! That'll be back up and running by crimbo! Hopefully can dial in and listen to organ
You need the wire wrap gun, it's electric ;)
The one i had was 110v with transformer, but would happily run on the +/- 50v (giving 100vdc)
Thanks! Yeah as mentioned in another comment below. I have one :D. But I like gojng a bit slower as it's less prone for me to make a mistake and ultimately it takes longer! Since it's not my job I'm not as practiced and even going slow it's only 10 minutes to do a bank of selectors so I'd prefer doing it manually :)
Think the one I have has a battery plug! I can't remember actually. Not used it much! :D
11:09 something very satisfying watching a phone being plugged in with one of those fancy connectors. Bet you felt like a proper BT engineer sam? :D
Not boring at all. I think anyone who has an interest in building and maintaining things should watch this. Everyone assumes that if you're someone who builds stuff, you use a 3D printer to make everything, and in fact most people do. But when a 3D printer breaks, most of the time they get thrown away and replaced with another 3D printer costing hundreds of dollars, because people don't have the skills or knowledge to fix them. The shelves of the mechanical engineering department at my old college are stacked with dozens of broken 3D printers.
:D nice! cheers!
Admiración, admirable
Cable lacing, a lost art. I worked on an ITT electronic switch back in the 70's that was "programmed" by wire wrapping leads to various pins. I still have that wire wrap tool. Ironically, I can configure a Raspberry Pi as a PBX to do 100 things more than that mechanical switch.
nice!!
Wirewrap always looks so nice. :)
This is gonna sound silly, but even though the set up has gotten bigger, its still the same. It's just so eloquent and complicated all at once. So cool.
You and the others really smacked and whacked this all together. It's just... so danged cool. :O
Sam! Thanks for sharing and your videos are NEVER boring! The talent and knowledge of the people who designed exchanges like this, which are purely electro mechanical, and without any CAD or computers is mind blowing! Keep up the good work Sir! ❤
Save the cut-off ends of all those wires! If they're what I think, they're *really* great for solderless breadboarding... all those colors, too!
they do work well!
i love watching these telephone exchange videos!!!
giid ti biw :D
that was meant to say good to know haha
Cool!
I still have no clue what's going on... but I like the clicking
somehow feeding a MIDI sequence into your group selectors could make some really fun percussion... it does ratchets and everything....
I did :) there's a vid on it in the exchange playlist
@@LOOKMUMNOCOMPUTER hot damn! I missed that one. Will look back.
Love your work
What a beast to work on! Love your looms Sam but please don't use velco mate as a way people can't fiddle with things, Imagine getting a few spicy low voltage ac off them. Wouldn't kill someone but give them a tingle. Always love your work brother!
Velcro? Yeah that part is off limit. No one goes past the barrier. Velcro is only on displays without power in them otherwise. The ones with electricity in them are screwed in. This one poses no danger as is off limits anyway.
Cheers tho!
How would the off hook tone sound like? May you please do a video on the off hook tone? Thank you.
Compeli-cated doodley-doos indeed.
Should look into getting a wire wrap gun... esp one of those older all-metal ones.
I have got one! Buti prefer this manual one as it makes me go slower, less prone to messing up which ends up taking longer. So opt for this as it is only a 10 minute job with a manual one anyways. :)
@@LOOKMUMNOCOMPUTER ah :)
ill keep my ears open for group selectors. I think ive sold my last ones now. Looks like you need a couple of linefinders. But its looking good as is.. Is there also a ringer on the back of your C Rack ? with 2 ascociated relay sets..
Cheers! As for the c rack. No it was a second rack so all of that stuff was pulled out!
Did ya see the IKS exploration video ?
no nbut just searched up, cool! had seen videos of kingsway before but cool to see another! cheers
Please teach this telephone thing to make music ;-)
When can you get dial up internet working over the telephone exchange?
Hopefully soon. Got the parts. But you know how it goes!
@@LOOKMUMNOCOMPUTER Yup but be very cool when it happens, get some old tech online through the exchange. How is power though does it all use a lot of juice? You got that covered I am sure though it's all looking good.
surprisingly uses next to nothing, as when not in use it uses next to zero, surprisingly on a busy day at museum lots of calling over 3-4 hours it used about 0.5kwh, so this setup is surprisingly more efficient than a computer doing the same job, im sure a bigger exchange would be a different story, but yeah. surprising@@HomelessTechnology
If you pick up the phone and don't dial out and leave it off the hook for a long time, does these type of switches sound an alarm through the Telephone receiver?
Interesting way of wiring from the Group selector banks. I don't think that ties in with how I remember how UAX 13 was wired back in the day . The group selector banks were wired to the final selectors not to other group selectors
Yep! It's not how they would usually work. But it's more descriptive of how telecom worked in the grander scheme of things like this. So opted to have some artistic licensing when wiring them up. This way results in 4 number phone numbers but if you use a phone on the same rack "local" you can get away with just using 3 numbers as straight away dialling the final selectors.
I’m a bit confused. How many oscillators is it ? Hasn’t it got any presets ?
Also, who is this band “Rab” he’s got the T-shirt for ?
Let's see, there's one oscillator in the phone dial. I don't know enough of how it works but I think there's also an oscillator in each selector. So maybe something like 31 in all?
As far as I know basically everyone is wanting selectors at the minute (even us lol). But yeah my fathers has been looking for some for a while now. Might be able to get some but I really don't know.
Nice! UAX13 selectors is it?
where is it you work that needs selectors? is it a museum?
@@LOOKMUMNOCOMPUTER yeah, I cant remember the spesifics of what they are for but its needed for either the test desk My father got working to dial into his exchange, or its for his register translator to connect to the exchange. either way there is an almost empty rack with only a couple on it.
@@THISMUSEUMISNOTOBSOLETE lol no it just my fathers hobby.
What are the Divert a call units for?
Level 6? "To level 4 I think".
Sorry? Not sure what you mean. Cheers!
@@LOOKMUMNOCOMPUTER Sorry Sam, its a line from "The Path Of Least Resistance" by The Human League". It's from the late 70s, so I guess you wouldn't be familiar with it.
aha nice@! my bad :D@@TheDavidPoole
Love your content mate! Im not a step-by-step guy (crossbar is my world) but your wiring is wrong. Selector outputs go to next selectors or connectors. You are looping around on same stage which is extremly dangerous because you could tie-up whole exchange with one call. This should never happen in a real world scenario...
yep thats the point, it is purposeful to do so, it is a museum piece and giving it the ability to all being able to be used further explains the function. its not dangerous it is educational :)
Is it just me, or could a teletype machine in California @CuriousMarc be used to dial a phone exchange in the UK and transmit 7 bit data through the exchange to a device like say a Pipe Organ in order to have the midi functionality of said organ operate? @Lookmomnocomputer
