Schematics and architecture details for DAVIAC now available at daviac.net
I'm certain there were competitions between programmers back in the day to make programs with the sickest beats
I'd try to make it swing by introducing ternary rhythm (3 steps per count) and the fudge the delay of the third beat and very little happen in the second :)
😂
I absolutely love how the clock signal is just a motor and 2 contact switches.
Overclock = spin that motor faster hahaha
@@GospodinJeanWell, literally just run the motor at higher voltage, a.k.a 'overclock' 😅
The clicking is described by the auto closed captions as "music".
accurate :)
It's not wrong...
If DOOM was running on something like this you'd not need a soundtrack.
If DOOM was running on this we'd need to wait until heat death of the universe for level to finally load :)
@@MarcinKralka nah, probably just a few thousand years
Doom would need a block stacked with these, at which point you couldn't pay the electricity to run it.
@@MarcinKralkaif it was big enough maybe not
So musical. Must've been pretty wild to be a computer scientist in the 1940's.
computer scientists don't make computers.
@@ShadowViking47 Pretty sure they used to back then.
@@thepetrarcticwar2778 Naw when computers were new new it was electrical engineers that actually designed computers. That included the hardware, software, architecture, etc.
Computer engineering (a newer field) is a subtype of electrical engineering.
@@ShadowViking47 Alan Turing (the most famous computer scientist) designed his own version of Bombe, the electromechanical Enigma decrypter. And electrical engineers helped him to build it.
@@adamrak7560 Makes sense. He obviously had a great understand of the actual computing (comp sci) but by trade didn't actually have the skills to design the computer (electrical/comp eng) that did the computing.
I love how percussive it is!
Better beat than most rap producers out there.
F**king trap beats, man... I used to kinda like the sound of an 808, but those damn hi-hats are worse than nails on a chalkboard now.
Gives a whole new meaning to "clock motor".
i like the rythm it makes
That machine sure lays down the beat
That is one of the craziest things I've ever seen. Good job!
This is really amazing. Has this been written up anywhere? It'd be fascinating to read some of the theory of its operation along with some of the engineering challenges around designing and building such a beast!
Nice! It’s kinda tribal sounding, definitely an awesome rhythm
i love the sounds of relays
Sound like something from ‘look mom no computer’ :-)
It has a nice catchy beat to it too!
I really like your clock generator :)
How many watts is this computer drawing?
@David Warren So to scale up to something similar as a moderate mobile phone you would need a nuclear reactor for power and ...... yeah not even going to guess how much of the earth you would need to convert to relays. A bit like the Universal Paperclips challenge :)
Thanks for the reply. Awesome project!
@@FrancSchiphorst a bit of lightning for 1.21 GW
The machine draws about 5 amp at 12V, so about 60 watt.
Hola DAVIAC-1. Soy aficionado a la electrónica y me gustó mucho tu vídeo. Definitivamente eres un máster creativo. Estoy seguro que te llevó mucho tiempo para realizar este proyecto y no me imagino las horas que pasaste desarrollando los circuitos y conexiones para que funcionara. Admiro mucho tu ingenio. Gracias por compartirlo. Saludos a todos ¡¡¡¡
Gracias e obrigado.
Si mucho tiempo!
2000 horas +.
:)
this is so cool. konrad zuse would love it.
The adder is pure Zuse.
@@davidwarren2597 Was'nt Zuse a decimal computer rather than binary ?
@@pascalcoole2725 the adder section is a direct copy of a Zuse adder.
I love the machine kachunk kachunk kachunk sounds
I love how the clock is just a cam on a motor.
Wow amazing piece of technology
That's full cold war retro. This could be the next Rammstein song!
It’s about 1947-1950 era.
But sure, Rammstein!!
:)
thats so cool man, good job.
Back in the day, you didnt click computer mouse, computer mouse clicked you
Just beautiful)
That is one groovy computer!
nice drum kit!
Bro this is true music
yooo that beat is sickk
Awesome! I want to build one too, but don’t know how to start. The paper that Shannon published with logic gates using relays uses current to represent a 0 (or false), do you know why?
Probably because active low (0=current or voltage) was best for resistor/transistor (RTL) logic.
I use 1=current/12V and 0=.
Either is fine for this relay technology.
Brilliant!
This thing have rhythm
Let's go in RIVERDANCE with some RELAY'S!
relays
can I use this as the beat for my new prog band's new hit single?
Sounds like an PSTN switch house
this beat is fire 🔥
¿porque utiliza un motor para hacer el clock ?
Now te sweetest sound is a VFD, the rest is old internal combustion engines and te 2021 sound.
nice beat
Electro-mechanical computer
Clock is a electric motor ?
Yes, geared DC with a big wire wound variable resistor for “speed”.
Motor, simple cam, two limit switches.
One switch sets a relay latch, the other switch resets.
There is a rythm there at the end that is basically a dance song. :-)
You have achieved 200 flops without floatong point. Impressive.
The motor creates a clock with two limit switch, is that right?
Correct
I feel some kind of rhythm
that is a very unique clock
See how the motor cam pushes alternating switches.
One switch sets a relay latch, the next switch resets the latch.
This gives a very nice square wave output.
Funny how an obsolete technology can be so cool and fun.
perfect
Отличная работа
Sounds like Cyberpunk-Flamenco...
Can this run tiny ship
good music
yes, worth it just for the sound😆
AAAaannd how much power does it draw ? 😛
Yeah this is impressive but relay computers don't just use RAM or ROM, so you have created an emulation of a relay computer with digital components or what exactly do you call it?
It's a computer from a science fiction movie I saw a long time ago.
Yep, the clicks you are hearing are from the relay’s electromechanical function. They used electromagnetism to make connections. And every time you’d activate the relay, it would make a click. They are just mechanical transistors. Relay computers never get old. The music of computation
Niiiiice
Add the sound to spotify
Drum'n'relay
"Instead we present to you, the sonic recreation of the end of the world.

I grasped those beats for my next composition 😜
sounds similar to how the bombe sounded in the "The imitation game".
Definitely Turing and Zuse inspired.
LOL, the reason that semiconductors were the enablers of modern computers is their staggeringly low failure rate per junction. I can only assume that a computer with hundreds of electromechanical switches will have an MTBF in minutes :)
What a heroic.....and likely pointless.....endeavour.
k, lets do rope memory next. i love the sound of that. not rope, the relays
Hmmm….rope memory.
I’ll try to work out a relay version of that.
:)
@@davidwarren2597 that would actually be cool. There are two kind, I mentioned rope but one that would employ more relays is core memory and you would have to source a memory plane, its not something u wanna make.
In rope memory I believe the cores are special material, or maybe that was core memory I cannot remember. Everything i know on the subject had come from CuriosMarc on YT and is THE Apollo Guidance Computer channel
But, can it run crysis?
the program is now running in ram
Great music 😂
But can it run minesweeper?
All the gates run in lock-step with the master clock, I suppose.
Correct.
The clock runs the sequencer which orders the timing on “buttons to push”, the selection of which depends on the current instruction.
That's how electronic music was invented
But can it play doom?
O motor funciona como clock?
Si, o motor funcions como clock.
Elle esta “variable speed” tambem.
la computadora tiene buen ritmo 🎶🎶😂
cuantos siglos tarda en minar un bitcoin?
Muito!
can I play DOOM on it?
Gta 5 kaldırır mı?
Imagine running call of duty on this computer
wow
Can you run Doom?
Konrad Zuse?
The adder is Zuse
I hate to ask how much money is in this project...
It even have a trap hihat
1:02 start beat
Реле и светодиоды😂 Нужно было использовать неоновые лампы
star wars soundtrack
If it's a transistor, it must be fast
ok now make it run riverdance
relay computer
motor clock :)
This make A Music
비트 주세요!
OMG
в конце релейный компьютер принял российский марш
Quick somebody use this as a trap beat!
What an immense waste of time
Waste of time
Yep
But I am enjoying it!
Why? What hobbies do you have that isn’t a waste of time? Anyway, luckily it’s not your time he’s wasting, so why even bother wasting your time commenting.
>Waste of t-ACK!!!!!!!!
@@davidwarren2597 many others enjoying it too now! Including me.
