Found this series before I started college, now I'm working on my grad degree and still come back to visit this channel to rewatch these videos to just refresh why I love what I'm doing - microprocessor design. Thank you for making these, friedo, still hope to see more in the future!

[@kikeekik]

Same, I'm graduating this year and I remember that I watched my first Clickety Clack video while I should been studying for computer architecture first year class, I hope he would keep releasing more videos, I need to see that computer working

[@BuddyCorp]

Fantastic videos, well presented and beautifully edited. I'm hoping for a conclusion to the series.

[@EpicVideoTime4You]

This has simply been the most beautiful series on KZbin. I hope this will have a grand finale! :)

[@PelDaddy]

Would love to see any progress since this video. These are amazing videos, and the computer is really coming along. I love how you share you mistakes as you go.

[@edgeeffect]

This project is one of the very best thinks I've ever seen on KZbin... long live Dr. Zuse.

[@brianpoi5117]

Talk about a cliff hanger. I wish this series continued.

[@Cracked1ce]

Would love to see you come back and make videos again. No pressure to continue the project, just new videos of whatever you are currently working on. I think alot of people understand that sometimes a project needs a good break before you get inspired again to work on it.

[@LeonirZimmermann]

The best work on a modern Relay Computer!

[@johnpenner5182]

love this project and your updates - konrad zuse with the Z1 was the original digital relay computer guy. love your didactic sense of construction - with the mini LEDs giving an indication to whats going on in the system. it is meditative to watch you building this system from the relay gates on up, and the sound it makes whilst computing is really coo. i wrote a chess programme for macOS (called pChess) which emitted sounds while it was recursively searching the highest static evaluation, and it was a way of hearing the computation - in much the same way that the relays naturally provide. thx for this. 🙏

[@Zenas521]

This episode made me happy. You have the gift of teaching. This is so cool!

[@tvgerbil1984]

The series was so well done. Regrettably it was never completed.

[@ziotdev5250]

[@ingojochl9444]

[@FairfaceCZ]

I think he is stuck building kilobytes of relay memory :)

[@absurdengineering]

I’m putting together a 1024 bit (128 byte) relay RAM… 2048 relays, not counting the external row decoders etc - those 2,000 are just the bistable (latching) bit storage registers and their bus couplers. Since it’s a diode-less design, the 2 relays per bit is the bare minimum, since each bit has two lines (a read line and a separate write line). And I still need a 512 byte ROM, so that will be another 2000 selector relays plus dip switches. It gets tedious sometimes but is also satisfying.

Check out Ben Eater on youtube.

[@czmik]

Nice trick with taping things down before soldering.

[@computeraidedworld1148]

I've always wanted to build a primitive computer like yours but out of vacuum tubes or one from just logic gates, not that they already are maybe even use wire wrapping.

[@HackersbenchPage]

PLEASE tell me there are more videos coming!!! Awesome work. :-)

[@martinschulte3613]

Will there be a next video?

[@computeraidedworld1148]

Hey will/are you going to release plans for this once its done?

[@goodmaro]

In the test starting at 14:10 I can hear the data cascade "ripple" as you say thru the adder, then the 200 msec delay you put in before the next enable signal. What would happen if you tried to use the elements of your CPU asynchronously, using its own output as an enable signal for each step? Would the variable time for each addition operation, because of the changing number of carriages, screw things up? Or is there some data bit you could effectively use as a "wait" signal, a "NOT enable", to queue up the operations properly?

[@arthurvlog6259]

We miss you! Don't leave unclosed gestalts behind ;) if you know what I mean...

[@TheJeb52]

the clicking is very relaxing to listen to

[@computeraidedworld1148]

You should build a circuit that checks the relays if they are working, so if one is broken it will give a code in binary that would tell you witch one, this could be too complicated but just an idea, kind of like a POST for it

[@goodmaro]

How would you work that physically? With an overlay board that could address each relay and be plugged in and out?

[@edgeeffect]

I was wondering about your PCB design. Do you have a ground plane on one side and a positive plain on the other side?

[@ClicketyClack]

Yep, ground on bottom and +V on top.

[@OriginalJetForMe]

Dang. Four years ago. Hope he’s okay.

[@QBarszcz]

Please continue this !!!!

[@paulsimpson6290]

Can you post links to your suppliers? Who do you use for PCB production? Where do you source your relays at a reasonable price (in these quantities, even a few cents has a significant effect on project cost!)

[@lander1591]

Hand wind small coils around small glass magnetic reed switches to make relays that are more compact and energy efficient ;)

[@sparkey9098]

you missed soldering 3 pins

[@ClicketyClack]

I got them later. :)

[@sparkey9098]

Better yet you where trying to check if people are vigilant in watching your videos

[@inerlogic]

I was screaming at the tv!

[@computeraidedworld1148]

How much ram is this going to have? And how are you going to be able to store instructions?

[@ClicketyClack]

I'm just going to use a small IC for RAM; haven't decided how much yet. Instructions will be stored in a separate instruction register which hasn't been built yet.

[@ccutts63]

Could you possibly use an array of dip switches for ram?

[@computeraidedworld1148]

Christian Cutts no ram would need to be fast and automated there's a few videos out there that discribe it

[@bjondersson]

Magnetic core memory would be cool.

[@gorazdnovsak3705]

[@TheJeb52]

hmmm, 2 years ago, what is happening, my dude?

[@gt_masterman]

So how do those rail resistors for the leds work? Are they just a bunch of resistors in parrallel in a nice formfactor?

[@ClicketyClack]

They're called resistor networks; these particular ones each have 10 resistors inside with one common terminal, so 11 pins total.

[@gt_masterman]

@@ClicketyClack where do you get the ones with 11 pins? I can only find 10-pin versions

[@computeraidedworld1148]

Here's an idea for the instructions, you could build a broad that when the computer is turned on those relays will flip on like a rom, so then the cpu can refer to the "instructions board" and complete an operation, in only a beginner so bear with me

[@markrgreenlane]
