I like the clickety clack sound of the relays on this. It's a good audible illustration of what goes on in the computer when it does a calculation or executes code and the various gates switch on and off.
I started on your channel with the Vacuum Tube computer... It's interesting to go back to this and see the origins of your interest in "1 bit stuff". :)
I never understood why BCD was a thing, but after watching these past two videos and thinking about building a decimal displaying calculator, I can now appreciate they are trading vast complexity in the display of decimal from standard binary for small increase in complexity of the adder at the expense of some RAM density. I can see how that might be a better choice for certain applications.
Hi David, I'm Anu. My husband and I watched your work on Veritasium's channel on how first computers were made from light bulbs. We were so thrilled to watch & learned so much. My husband thinks this is the best video he's watched on the internet. For my husband's bday & father's day, i was hoping to gift him something special & memorable that he would love & get excited about! I wanted to gift him the 10-bit Binary Relay Calculator from the video. Would you be able to oblige the request if i were to buy it?
I'd like to see what that adder does when you try to subtract bigger number from a smaller number. They way you described the working it would seem that you get the right answer but without the eleventh bit lighted.
Hi i’m 13 and i want to build a relay calculator for a science contest and i would realy like some help. Is it complicated to build and can i build it on a blanc pcb? I know Im 4 years late so you probably wont respond but it would be realy apreciated.
Hi! Thanks for watching! I don't really have a schematic as I just kind of designed it by the seat of my pants. I do have photos of how I designed the individual boards up on my website linked below. Let me know if you have any questions! usagimotors.com/2020/03/09/electronics-a-10-bit-full-adder/
Dunno how Usagi does it, given no drawings maybe he don't either. Here's how I would do it... Maybe not as clickety, since all borrows happen in unison by series prefix, doesn't use ripple. drive.google.com/file/d/1ME5yGlUR0OzEspfjTq68mm3btHjxSo0s/view?usp=sharing
Thank you! I actually really wanted bigger toggle switches, like on the old Imsai or something, but space was at an absolute premium. Even with these tiny little switches, I almost didn't have enough room on the board.

hi! I want to built one from this where can i find more information about the circuit diagrams,connections ,and other componends
Hi! Could you share the DesignSpark PCB schematic? and the Gerber files? and the G-Code?
Hello, your website cannot be opened, can you provide a new website
Couldn't you wire the subtract switch to kill power to bit 11 on the front panel when in subtraction mode?
this is so cool that you can teaching child how binary works in computer

we need a drop for this.

hola soy nuevo en el canal y me gustaria hacer la calculadora alguien sabe donde puedo conseguir los diseños del circuito
Relay computers are cool! 😊
circuit diagram=?

@@UsagiElectric Thank you! Makes sense, that's how my designs are as well!

@@UsagiElectric The link is broken. Can you provide a valid one?
@Usagi Electric could you please provide the circuit diagram and components list to make this adder
That's awesome. You could make it easier to select bits by using push on push off button.
Thank you! I actually really wanted bigger toggle switches, like on the old Imsai or something, but space was at an absolute premium. Even with these tiny little switches, I almost didn't have enough room on the board.
Wow!
Really cool!
I just want to buy one. If you can just give me a link I would really appreciate it! 😄😄
Scale up a relay computer to the functionality of a cell phone, and your phone probably wouldn't fit in Norway. It would be really really loud too!
