All of the Vlogs and DRUM LOOPS from this machine are available here www.patreon.com/lookmumnocomputer :) This was not the machine I originally had in mind. I hope to make a version 2 which is a more performative sequencer. As this design does not lend itself to live sequencing. The next machine is a bit more involved circuit wise as it adds another dimension to the wire. scanning. But if I get the rope core flame lit again there will be another
@@Lantertronics haha it's all good. It comes up quite a lot how much I mispronounce and use the wrong words for things and mis spell/punctuate. It's not that I have a problem with it. I just don't understand why energy is spent on something when the communication has been understood that's all. Having had a lifelong struggle with spelling and phonetics i see the language and writing as something to interpret and evolve, im aware not everyone sees it that way. grammar police are the antagonists in my life haha.
Oh, I see I wasn't the only person to comment on it. Yeah, different people have different accents, all are valid. Yours is part of your awesome vibe. Keep the vibes going!
@@LOOKMUMNOCOMPUTER I can't argue with how it's pronounced when the person understands what they are doing 100x more than me! I'm not here for the english lesson, I'm here for the wild creations.
As someone who was building electronics back in the early 1970s, your energy, enthusiasim and electronic inventions continually amaze and entertain me.
He’s just fantastic honestly. I wish I could come up with a fraction of his ideas. I dream of playing with even a fraction of the cool stuff he plays with!
Its wonderous. I can't imagine what you originally had in mind off hand... but this thing is a work of pure technological art. The sentient life-forms born in the wires will be proud.
Im a 68 year old electronics technician my first introduction to electronic music was Synergy, Tomita ,and Kraftwerk the later of which i seen at a small theater in coconut grove Florida in 1975. I love your creations and art. In the event of an electronic apocalypse you and others like us who still retain the knowledge of elemental electronics will be invaluable to rebuild our society and it's technology. Way to go. All the kids in school around the world should be learning electronics technology from kindergarten on as a part of the 3 R's . Guess basic education would be called the ERRR's then. You keep me loving electronics an all things quirky 🤪 ✨️ 🖖👽✌️🙂
At the CORE (sorry, not sorry) of basically every incredible synthesizer ever designed, from MOOG to Synclavier to KORG is a brain exactly like yours. This is profoundly beautiful!
An absolute astonishing work, hats off. I really hope young people become interested in doing electronics, music and art because of your exceptional way to do things simple and not to overcomplicate things. I really love what you do!
If you had done this back in the 70s, you could be a legend in music today! This is awesome technical skills combined with musical spirit! I really love what you do and I admire how much time and effort you put into these weird ideas!
Your explanation of rope memory was explained so clearly, that for the first time I finally understood the concept. And I was shocked that I didn't realize it before, they are just transformers! Nothing more than that! Finally, that's the trick! Sure you can add bells and whistles, but in essence they are just transformers. Where the beauty is in the ease of addressing the data and the way the fact that no hardware is needed (switches or jumpers) to define the value of the bits, just wire. So thank you for showing us this fun project and presenting it to us with your inspiring enthusiasm.
I remember learning about rope core memory listening to the 13 Minutes to the Moon BBC radio series about the Apollo 11 landing (would 100% recommend a listen). So cool to see the technology used to make music! 😁
What's fun is that weaving and computation have a VERY old history. In fact, some of the first mechanical computation devices were for weaving machines. The first punch cards were pattern cards for incredibly complex looms.
I love that the pieces in the museum are all great showcases of early age electronics. Using music to show what each technology does is just a really great way to make it easy to understand.
i cant get over how much you feel music :D it's like the force or something! you use your instruments as well as you understand their workings. glad i subscribed.
As an electronic engineer this was a blind spot for me. I love to know these old ways of doing things. I am glad you showed off a build using this principle.
Whoa! And here I was just thinking a different color wire for each loop. EL for the selected loop would be friggin' amazing. Zif this isn't awesome enough. From a technical standpoint, I'd think the fact that EL has current going in on one layer and out on the other would mean the magnetic fields would cancel each other out. But, if one layer was powered at one end, and the other at the other end, that might fix that.
Another comment mentioned to put the ferrite coils on movable sliders to make passing the wires through easier. It would be next level to incorporate analog loom weaving machinery to allow the operator or a pre-programmed mechanism to rapidly weave the wires in real time to change the beat.
Absolutely bloody outstanding!! I actually cheered when the machine started to work. I watch your videos with amazement…. I’d love to be able to make a tenth of of the things you create. THANK YOU !!😊
Love the fact that you understand both music and electronics. Very much my background but over the years been involved in engineering. I can remember being excited as you with producing electronic music. Keep the enjoyment coming.
Analog technology will never fade away, there will be always someone like you that loves experimentig and have fun with old technology and obsolete components. ANALOG WILL NEVER DIE!!!
What a _fascinating_ bit of electronics history. I saw a video of some people restoring that Apollo guidance computer mentioned in this video. The conspiracy nuts say computers weren't advanced enough to send people to the moon in the 60s. Well. That's half right. They really had to come up with new methods of doing certain things and do a lot of this rope memory programming by hand. They had no business going to the moon with that technology but they made it work. They invented their way to the moon and back. I always wondered what else could be done with this stuff. This is such a cool idea. I wish I lived over there so I could come see this in person.
To be clear, I'm being a little facetious when I say the conspiracy nuts are half right. The computer tech did not exist when they began planning for Apollo. But by the time they sent the first humans to the moon, the technology _did_ exist because they invented it. The Apollo rockets were the first computers to use reprogrammable microcontrollers, the first integrated circuits and those computers ran on this rope memory technology. It didn't exist until Raytheon, a NASA contractor, invented it specifically for Apollo. So, the conspiracy nuts are half right but they're wrong when they say no one has ever been to the moon. Most of the programming of the rope memory modules for Apollo, the weaving, was done by women because it was akin to sewing and the men were doing more "important" work - the 60s were a different time. They used long needles to pass the thin wires through the magnetic cores. Those women sat there for hours for weeks just doing the weaving that he's doing in this video, just on a much larger scale.
I used to work for STC and we were developing an add-on for exchanges that replaced the ceramic core memory to add functionality. The exchange was oblivious to being manipulated - like the innocent victim of some kind of weird alien parasite! 👽
YOU are A MAD WIZARD and The GAWD of ANALOGUE!!!!!! WOW!!!I am so HAPPY that I stumbled across your channel, you blow my mind in EVERY VIDEO!!!!!!! THANK YOU for bringing me this Joy!!! You're just Amazing bro!!! :D
You know what? One of these days you need to cameo on Doctor Who - I can't imagine they'd find you difficult to write into something; not a whole lot of folks are waltzing about casually mixing the tech of the 70's with the tech of the future ;-)
3:26 that's exactly how the residual current circuit breaker works: it monitors the vector sum of all currents passing through a toroidal core transformer and if it's non-zero (like with a single wire going through), it'll induce a current in the secondary and activate the trip coil. If all currents sum up to zero (e.g. a current enters on one side and the same current enters on the other side, like with the loop here), no secondary current is induced. Slightly messy build, but a beautiful project nevertheless! Cool to know that some Soviet telecom tech was an inspiration. Adding a Nixie tube display for the program number would be a nice touch too. Or selecting the program with a phone dial.
I'm completely obsessed with the Apollo Guidance Computer. Springer published a great book on it, and I recommend everyone check out Scott Manley's video "The Computer Hack That Saved Apollo 14."
Fascinating time. I read something once where a hoax conspiracist employed a computer expert to research and debunk the AGC. The expert ended up writing a book on how groundbreaking it was😀
You're a bloody gem, wonderful explanation and use of technology. The only thing I have to say is its a com paar a tor not a com per a tor , it compares signals :)
Really nice and creative build, love to see all these existing technological elements combined in ways never done before. Cheers! Bet the inventor of the uniselector never imagined it being combined with core memory.
I suggest 8 channel analog (de)multiplexer 4051 It's basically 8 switches that controls to which pin the common should be connected according to the binary value on the input. You can use a binary counter (with a single 555 as a clock source) to cycle through the 8 outputs, and a 7 segment display driver with the associated display connected to the same input to show which line is currently selected.
Your dedication to using and reinventing the technology of yesteryear (aka my youth 😂) is amazing and hugely appreciated. Thanks for your enthusiasm and infectious love of electronics.
I find it amazing how much stuff you can done in such short time! New projects every few weeks and every single one is massive and well done. I wish I would get as much done in my time.
Amazing work. Here's an idea for the museum: You could find someone that's good at ICs, and contrast each of your historics-based creations with a modern equivalent. Just to show how far we've come, in addition to where we came from.
In a lot of cases, that'd be one chip, with the size dictated by the number of I/Os it needs. Which means a lot of stuff would be a 5mm square chip with some 0402 passives next to it and then a connector to send the signals off somewhere :)
I love it, I'm sure for a version two, there could be a color code for the notes. Darker colors, for the low notes, with lighter colors for the high ones. With the mid tones, being the color itself.
I had my doubts and did not follow this on Patreon, but, as usual, it turned out really cool. Plus, the braids look nice too. I love how you have multiple rhythms set up with one of those spool thingies. Mad mate!
Very NICE... Old school rope memory, thanks for building that and showing how it all works. The problem isn't just with the number of switches needed, but also you'd need diodes to isolate each switch otherwise closing two switches on different sequence steps would bridge them together... and that's no good... I know because I built a dip switch sequencer and had that bite me! LOL I have all the parts in my electronic collection, they are basic components, to build those circuits, maybe I might if I have time... Thanks for another great video!
If you added a visual pointer to a uni-selector, and a dial face for it to point at, the uni-selector could also serve as an indicator for which pattern/option is selected.
for this stuff you should use LM393 or LM339, they are designed comparators and faster, like 300 nSec. C7, 470nF is pretty big, my ADSR uses 2nF2. maybe the capacitor should be behind the diode, apparently the signal from the "coil" is larger than 0.7 Volt that it's makes it through the diode (D7), don't think you need that diode, negative voltages will close the FETS in the TL072 even further. you do need a 10nF capacitor on the voltage divider / threshold. Cool technology these coils.
Those triangle looking things - Op Amps or operational amplifiers. Very versatile building block with many applications including differential amplifier and compArator (not cOmparator). Amazing end result by the way, so I guess it doesn't really matter how you say it. Good job :)
Learned about rope core memory from 17776: What football will look like in the future, haha. Insane to think about them sending out space probes with this technology, but it did protect them from getting their memory corrupted by cosmic radiation and such. (I highly recommend 17776 btw, what a cool read.)
Wholly cow, this is amazing! I'm an electonics engineer an can understand what you are doing (obviously you know what your doin' ;-) ) but I would never have this idea. You're great!
It'd be fun if you had this hooked up to the telephone exchange, where each pattern gets its own number, and a modem converted the bit patterns so you could dial in from another part of the museum and output the sequence to a synth.
Even with tech that old, it's still somewhat portable although a bit hefty. But now it's possible to have what amounts to a whole DAW (a studio's worth of things like that) on the smartphone that fits in your pocket.
Common name for the enamel coated wire in the USA is "magnet wire" 32 AWG (american wire gauge) is comparable to 0.2mm diameter wire. Enamel has surpassed lacquer as the usual coating.

Since you're using a high frequency, I wonder if you could use EL wire to visualize some aspect of what's happening
Yes! Red EL Wire shaped like a vacuum tube filament & put inside large faux tubes to mount on top
@@craigedgar2828 I meant using EL wire to weave the core memory sequences but that sounds cool too
I wonder if that would work. Sounds like it might.
Whoa! And here I was just thinking a different color wire for each loop. EL for the selected loop would be friggin' amazing. Zif this isn't awesome enough.
From a technical standpoint, I'd think the fact that EL has current going in on one layer and out on the other would mean the magnetic fields would cancel each other out. But, if one layer was powered at one end, and the other at the other end, that might fix that.
The Apollo computer also used electro-luminescent panels for the computer displays, so he'll be able to use two NASA technologies!
As a big Look Mum AND CuriousMarc fan, this checked all my boxes. What a great video and great exhibit for the museum. Keep it up friend!

The whole premise of this project is utter insanity and I'm here for it.
If you added a visual pointer to a uni-selector, and a dial face for it to point at, the uni-selector could also serve as an indicator for which pattern/option is selected.
I've had the idea of running audio signals through core-rope I'd be curious to see how it works as a filter
What a cool video. Amazing track at the end. Throw that in during a techno set and I’d be floating
I think this is absolutely amazing using this tech in this way.
how come all your projects are so awesome?
the BG music during the explanation of the principle was fantastic
The HP 9100 calculator used core rope memory for the control ROM and a variation of plated wire memory for the RAM.
for this stuff you should use LM393 or LM339, they are designed comparators and faster, like 300 nSec.
C7, 470nF is pretty big, my ADSR uses 2nF2. maybe the capacitor should be behind the diode, apparently the signal from the "coil" is larger than 0.7 Volt that it's makes it through the diode (D7), don't think you need that diode, negative voltages will close the FETS in the TL072 even further. you do need a 10nF capacitor on the voltage divider / threshold.
Cool technology these coils.
Very cool, love that the Patreons got involved weaving the beats too.
This is excellent.
Never stop doing what you do.
I love that this works so well. I was expecting you to use different coloured wires for each sequence though.
Holy... what a great application and demonstration of this classic technology! Great work, man. Very rad!!
You are the absolute coolest. Every project you have done is something interesting.
Another absolutely amazing and inspiring build! And I finally understand how rope core memory works!
And he dropped a banger with it. You are rad!

Extra like for the vintage B555D timer IC on your board that was manufactured in Eastern Germany in 1989 or 1979
Aha yes got these from an old closed down electronics shop in Germany when visiting gnostix labors in schwerin

It'd be fun if you had this hooked up to the telephone exchange, where each pattern gets its own number, and a modem converted the bit patterns so you could dial in from another part of the museum and output the sequence to a synth.
It's strangely comforting that a programmable computer can be built by hand with off the shelf stuff.
That looks amazing. Such a neat and methodical layout.
That’s awesome! Don’t forget the LM339 quad comparator chip.
555 is still alive! I recently discovered how useful this component is
