They also look comfortable somehow. Also, I saw a couple of videos showing (vacuum) tube rectifiers (mercury arc) from the old ages, and I was shocked at how cool they look while performing
As a software engineer who created square root and telephone dial reading subroutines in the 1960s, I am VERY impressed with this machine. Achieving this with relays is quite remarkable. Konrad Zuse actually invented his own cheap relay technology in his apartment, helped by friends. The technology has been lost (or at least I have been unable to find it); it involved strips of tin cut from tin cans, arranged in layered rectangles in right angles to layers below. We know that these relays were not too reliable, and were affected by nearby trolley cars. In his later designs, Zuse used commercial relays that worked much better. But they were also much more expensive. Your wiring is a beauty of clean organization.
Don't think they were relays at all. His first two computers were mechanical. The unreliable nature of these mechanical gates is what drove him to try electromechanical telephone relays instead. (After that, he tried vacuum/radio tubes, for speed.)
@@herrbonk3635 Yours is the first I've heard of Zuse having made completely mechanical computers. Do you have a reference for this? If not, how did you hear of it? My research told me that his first computers used unique homemade relays (not well described), stacking them in 3 dimensions, before changing to commercial telephone relays.
@@david203 Not completely mechanical iirc. It had some electromechanical parts. But the main logic, the gates, were mechanical. en.wikipedia.org/wiki/Z1_(computer)
@@herrbonk3635 Yes, you're right. 20000 parts, amazing! The Wikipedia articles on Z1, Z2, Z3, and Z4 don't seem to mention Zuse's remarkable homemade relays at all. They permitted very compact construction, but some versions were sensitive to trolley cars operating near his apartment.
Reminds me of that Futurama episode where fry and professor Farnsworth are trying to decode an alien letter from leela's parents to learn about her identity in a big ass machine that does those dings 😂
@@Jeffrey314159 gotta be 100% watch it as it spins an instruction is cycle every time one of the switches are pressed. Likely a JK flip flop. The odd cascades in the relays that seem to come in quick sequence are likely register flags being set which can happen independently of an instruction cycle.
This machine is truly wonderful. I love the fact it's about as real as it can get, purely mechanical. Hugely impressive, very well done. I've considered building a digital clock that runs on relay logic before. The physicality of them is really fantastic. And that ding when it finishes the calculation is just the icing on the cake.
This reminds me of the Casio 14-A, which was a relay-based 4-function calculator (no square root) that was produced from 1957 through 1959. It used 342 relays. There are several videos of it here on youtube.
Very cool, love the sound that relay computers make. I'm building a semi discrete serial CPU, lots of blinking led of course but no sound like relays do.
This really makes me appreciate my sweet sqrt() function which only takes a few microseconds to process. We've advanced such a long way from this technology in such a short time. Amazing build.
Very interesting, and I'm sure it was a lot of work. When I was in High School, in the '60s, I designed a Tic-Tac-Toe playing machine that used relays. I dudn't have enough relays to build all of it.
This is my new Favorite Object in the World. My friend and I were playing with this for 20 minutes yesterday in Bldg 99 and I have never seen a more beautifully crafted marriage of art and retro engineering. It is truly a thing of beauty.
Konrad Zuse's computers: Z1 (1938) was mechanical. Z2 (1940) had relays and mechanical memory, and did 16-bit fixed-point arithmetic. The Z3 (1941) used relays, and did 22-bit binary floating point (add, subtract, multiply, divide, square root). It executed programs from punched tape. Memory: 64 22-bit words. About 2,000 relays (1,400 for memory), 5.3 Hertz, 4000 watts. The next models continued improvements. en.wikipedia.org/wiki/Z3_(computer)
Dude, I absolutely LOVE this. Can't you put up more videos of it calculating other square roots? And I like the idea of the mechanical clock ;) Is it possible to crank it up a bit or is that already the maximum the relays are capable of coping with?
🤘👍👍👍🎥💥 Incredible! Chapeau bas! I'm deeply impressed! I really regret that you stopped to develop your channel. On the other hand, I'm not surprised, as you are doing a lot of great work and... yt doesn't promote your channel. 1.78k subscribers for such valuable content is like nothing!
A few aesthetic critiques: If they arent already, replace the front panel lights with low voltage incandescent for the authentic glow, print out (or better yet, acid etch some brass) a new number card for the input dial as the letters are a bit modern for the feel of the thing, likewise get rid of the vandal proof buttons and find something with a better turn of the 20th century feel (perhaps bakelite morse code paddle buttons? maybe modify the mechanism for a break over action, Bonus: the finger pad of the morse code sending device can have the function name inset into them. Perhaps brass instead of bakelite...), the cam that sets the pacing dump the microswitches and use either a voltage on the cam that contacts a piece of metal that sticks out to complete the circuit or get the simple copper strip contact closure type typically used as limit switches in old electronics (maybe make a little holder with a follower on the cam that pushes a little wooden stick that slides and closes the paddle style contacts, Bigger older school switch next to the dial (maybe something that mimics the large contactor mechanisms in factories of old, and finally the dial replace it with either a wheel style handle like on steam pipes or something like on the top of a variac (bonus points for adding an old brassy steamworks gauge to indicate either motor RPM or operations per second, with a yellow and red line area). As for the rear of the thing with all the LED lights......dont change a goddamn thing! The juxtaposition of the old timey front and the modernized rear is absolutely amazing! Oh, and DO NOT GET RID OF THE PLONK FINISH BELL!!!! Friggin perfect sound for the end of calculation. Those are just my two cents, some thoughts I had on the thing if you were open to ideas on a second version or overhaul at some point (or if someone else wants to build one of their own). All in all, awesome build, mate! 😎👍
I remember an analog machine solving complex diff equations. Wires were of pure gold. Many women who worked in the factory lost their vision... Back to xUSSR 1960s.
The Soviets built a desktop calculator's made entirely of relays in 1961. This commercial machine used 8 pin connection relays and a display/register made of electromechanical actuators. Get this, it appears to be all AC operated! Checkout the Museum of Old Soviet Calculators!
That's an awesome machine. How many relays you burn out per hundred calculations lol? I once worked with an old sharpening tool for long blades, a German made Gockel from the 70's, big cabinet and it was filled these things. You'd hear em click steady when the grinder moved side to side and when it was considering depth. We'd need to replace one every 5 weeks or so, never could predict a blowout.
What is the method used here? It is very fast for this frequency, electronic calculators spend thousands of cycles to calculate a square root, not one to ten cycles per digit.
Exactly my thought. It’s extremely fast. My guess is that it is not executing actual instructions, but a hard coded algorithm with significant parallelism
Very Cool! I ran across this old digital computer patent 3190554 that use air to compute and I thought it would make a good project for some tech high school student to make one today using 3D printing. I guess if Babbage had gone this air route he could have had his Diff. Engine made by the pipe organ industry and Lady Ida would have invented COBOL. Now I want a You Tube of Brush Bots doing computation by running a logic gate maze like had a swarm of Army Crabs do. The kids would love it!
+ufoengines lol, I can't really see him bringing in the organ industry. They'd probably reminded him too much of organ-grinders... I was working on one with a laser-cutter, but honestly it ended up being too much of a hassle. I got an adder and registers working, but didn't really have as much of the 'wow' factor as I though it would.
I've heard of Babbage's war on Organ Girders. Might be a movie idea here where invading Martians are defeated in 1913 with the help of forgotten Babbage Tech and old Organ Grinders in War of the Worlds 2
the URL is not working? Is it just me or..? Is the site down? And is there a link towards the schematic of your machine? As a tube-fanatic, who´s done a few concept-schematics of these (but nothing more, using vacuum tubes is possible, but not on my paycheck) together with relays gives quite a capable calculator. But dividing numbers is where I slammed my face into the ground, without much result. Analog computers too are still a bit far from being understood by me. I´ve got an old ´Radio´ (rather electronics with emphasis thereon) handbook from 1958 that goes into DIYing op-amps and such needed for analog computers, and explains (by using vacuum diodes) how to make gates etc. But never seen a complete schematic of a Root Puller :-) And that´s the one thing my own brain is NOT good in: Drawing roots, everything else is fine, if required on a piece of paper as help, but the root of whatever? Oh no, my brain explodes, so one of these would be handy. Add in a few dozen thyratrons and other tubes, a couple of 100 relays, and I´m done :-) There´s some old magazines articles for calculators, but never ran into a practical divider/rooter.

The phone dial and nixie tubes are the kind of aesthetics I'm missing so much in modern devices.
It certainly makes it feel much more human.
They also look comfortable somehow. Also, I saw a couple of videos showing (vacuum) tube rectifiers (mercury arc) from the old ages, and I was shocked at how cool they look while performing
They're shit, that's why they're not in modern devices.

You can see a reconstruction of a relay Zuse in Berlin, Technisches Museum and one tube machine if I remember well in Karlsruhe.

The operation is too complex, takes time and the operator should know when the operation was completed. It is a charm to hear that "ding" sound.
Reminds me of Willy Wonka. “I am now telling the computer EXACTLY what it can do with a lifetime supply of chocolate”
@@michaelhamilton3527 Now we can actually ask a computer these things, and get some kind of intelligible response. :p
I love that the clock generator is motor driven cam actuated microswitches with a little viewing window to see it running.
So it is a clock-timer and not just decorative - - ?

very nice. I like it much better than my calculator app. Can you build a relay machine that calculates integrals?
Do you have squematics or tutorial for this? Is amazing
