I like the rhytmetic sounds the relays make, it's musical. "20000 years of human history hitting their drums for this moment" kind of feeling.

There’s more to do with rhythms! There’s four instruction classes of differing sequence length. The challenge is to write code that both calculates something and also sounds great. Hmmm…..art form?

The Amiga computer, having a shared RAM between the CPU and the graphics ASIC did have a small program that could visualize the RAM - one pixel per bit. You could see variables change values and you could browser around the RAM by moving the mouse.

It was Harry Porter's ( not Potter ) relay computer which got me into Minecraft back in 2011 : kzread.info/dash/bejne/oGersqScnbbIYrg.html

I went to school to learn this stuff and it gave me an appreciation of our world today which is built on so many levels of this complex simplicity.

I feel like this would be an absolutely excellent teaching aid for how computers work on a basic level.

I LOVE IT!! I just LOVE IT !!! Lights blinking and the sound of relays clicking - just LOVELY!

For what it lacks in speed, it makes up for in style and sexy flashing lights! 🙂 Thank you - it's a beautiful piece of work!

This is insanely cool! I’d love to see a more detailed video of the rig and how it works

I used to work in Crossbar telephone exchanges. They used a 'marker' frame to calculate the best way to rout phone calls. Not quite like this but they were relay based and did calculations using relays only.

Wonderful, in 1988 I learned FORTRAN in college of electronic engineering.

HOLY smokes!! Every school needs one of these to teach people the basics of computers. How has the internet kept this marvel from me for over a year. And why can I like this video only once????

I am both amused and impressed! It sounds like an old telephone switching office. I tried building something like yours when I was a kid in the 70's but I don't think it ever worked.

This is amazing especially seeing the program loading into ram and the lights indicating the occupied memory spaces. Very cool.

about 20 years ago, i started designing a project named FUBAR -- fitting for a relay computer, and i had come up with new meanings for the letters, too, though all i can remember now is R stood for 'relay'. i had designed memory and several of the processor bits like an adder etc, but never built it. i always wanted to hear that sound, like i'm hearing from your project. thank you! i subscribed, i look forward

Damn. That things spits out some wicked beats. And the blinken lights are ace too!

Now I get why they always had the computers make that noise in the 1950s science fiction.

Minecraft Redstone Engineers when the Copper Bulb is used to its fullest extent

Such a retro-futuristic setup! Great job!

Rhytmetic shift left in assembly . . .wow; and it makes total sense and we've come along way from it. Holy shit.

Nice! It's what we all want from a nice big fully functional relay computer... the rhythm!!!! :) I'd love to listen to the full 9 minutes!!

The very first music played by a computer was done by a hobbyist sometime in the 1970s. They ACCIDENTALLY discovered that their 8008 processor based scratch-built computer, when used next to an AM radio, caused a tone when the radio was tuned to harmonic of the processor's frequency, and they subsequently created a program consisting of "empty loops" of different lengths to make a song play on the radio.

@Wingnut353

@@tyson31415That's absolutely false. The fist computer music was CISR Mark 1 in 1951, and the second was the Machester Mark 1 playing a few difference songs of which we still have existing recordings. Bell labs developed a musical computer language and Beat Cannon by John Robinson Pierce was released in 1960... all of these predate your claim by 10-20 years. Peter Zinovieff composed January Tensions on a PDP-8 one of the first private individuals to buy a computer and produce music also predating your claim by several years. The technique you describe was almost certainly discovered on mini computers or the like in the 60s (larger computers probably would have buses that would be TOO noisy). The IBM 1401 at a bare minimum is documented to have played AM radio music via BUS EMI... and that was in operation from 1964-1971.... the fact is this was probably common knowledge even longer than that as everybody had AM radios, and computers with lots of bus EMI had been around since the 50s....

when each small relay costs $3... and the big ones $8 with the mounting socket.. yeah id think about doing something else

Obviously it doesn't have much purpose. Relay logic consumes a lot of power, is large, hard to manufacture, and very slow, but it is SO COOL HEARING IT WORK.

Incredible work, aesthetically satisfying sound and lights and it actually does something too. I think I see either the address register or the program counter.

Those blinkenlight arrays are really the icing on the cake!

Just love the sound of physical bits!

This is literally something I've wanted to do my whole life. Make a computer out of relays. That's awesome.

I love it, analog and digital. It seems like it’s going to have come back in certain situations.

That noise reminds me of every middle school and high school class where there was always at least 4 kids at the back of the class tapping beats on the desk with their pencils before the teacher arrived

This is astonishing! What an accomplishment!

Silent and swift. Sounds like a nice short disco. Really impressed, no jokes.

i have literally no idea what I just watched, I just know it's amazing and quite frankly beautiful

It's good to see somebody keep the old knowledge alive. A tree without roots won't stand up to the storm.

I was introduced with computer when I was around 11 years old It was an 8088 PC with green screen . I was Amazed ..... And this film makes me Amazed more 😊

That is a beautiful piece of work. Electric Poetry.

So impressive. I could watch that all day

I am most definitely using this sound as a sample for music

Good to see that Doc and Sprocket are still around.

The dog is amazed by the computer's operation.

Now that is one beautiful computer you have sir, and same for your doggo..

He's like an evil villan but with a dog instead of a cat on his lap

This is so AMAZINGLY BEAUTIFUL!

okay, that's awesome-- the visualization on the memory as well

It's a thing of beauty. Now you have to mount it in some cool artsy way. Call it something like "ASL in 9 Minutes of Coolness".

I wanna see the ladder logic on this bad boy. This is cool as hell

That is insane! Congratulations.

This is not only functional and a design masterpiece itself no.... It is beautiful to watch and I have problems to shut my mouth when I take a look at this....

Love the RAM loading part! beautiful!

I'm most amazed you have no problem touching it after having your staticky dog in your lap with synthetic fabrics on. A solid state computer would never survive that repeatedly. I know it's not a huge issue. I've shocked ICs (74HC173 D latches) and LEDs with a small van de graff generator right on the data pins and they still worked fine after. I still feel the need to touch a ground source before working if I just put on a sweater or touched a cat.

It looks like it’s mounted to a bi-fold door. I thought, whenever I see old doors laying around I also naturally think, “this would make a perfect computer mount”!

We need more relay computers in the world, they sound incredible

this is the coolest computer I've ever seen!

going to use that sound in my music, cool groove it makes when you run it!

I like the sound. Great computer.

Only 90 years late. This is fantastic!

Completely crazy and absolutely brilliant! Love it! :-)

that's SOOO cool I wish I had projects that exciting when I took Electrical Engineering

Nice modular synth!

This is beyond cool! And it sounds similar to the early Star Trek computers 😊

Star Trek TOS just called. The Enterprise wants it's computer back.

And that's where we get the terms "Flops" - from the sound the relays used to make 😀

I get the fascination people have with things like clockwork and other intricate machinery. Some people feel like that's all gone, and mourn the loss, but I feel like that's a lack of imagination. It's all still here-in silicon. I like things like the computer shown in the video, because it brings the intricacy of digital computers to the forefront. If someone wants to keep that sense of wonder gotten from complexity and precision, I recommend software development-low-level programming in particular.
