Dear Chris, Thank you for sharing another truly captivating update on the PCB ESP32 ZX Spectrum project. Here is my encouraging gush if you may bear with such! Your attention to detail and careful design work is truly commendable, making the entire journey of watching this project unfold an absolute delight. The moment you discussed the expansion port at 5:15 in the video, my imagination was ignited by the endless possibilities it presents. It's truly tantalizing to think about the potential that this feature holds for the project. The beauty of your project and the video itself is truly remarkable. Your dedication to keeping the momentum going and maintaining a captivating and focused approach is truly admirable. It's clear that a tremendous amount of effort and passion goes into every aspect of your work, and it's deeply appreciated by all of us who are following your progress. Thank you for continuing to share this exciting journey with us. Your updates never fail to spark a sense of enthusiasm and wonder, and it's a pleasure to be a part of it. Looking forward to the next installment with great anticipation. Warm regards, //\/\\ //\/\\
A friend and I used to discuss woodworking and networking, often swapping between the two subjects in the same evening. We settled on root-ing was LAN, r-out-ing was woodwork as it got really confusing otherwise. RIP Bob; it would have been fun to include pcb routing, which is clearly pronounced "scone".
"Root"-ing (tee-hee) when it involves paths of movement and "rowt"-ing when it involves cutting. Therefore I've got a network "root"er and used to deliver newspapers on my paper "root". I will utterly "rowt" my enemies with my power "rowt"er.
It *is* lovely. This is a very interesting project. Thanks for sharing this video. Also, depending on where you’re from, it’s either pronounced “routing”, or, alternately, “routing”. :D
Route like fruit = British english Route like shout = American english Route like R̷̲̩͚̰̃͑͆O̸̙̠̹͙͖̲̠̦̤͐͑͒̍́͊͊̔̋͝͝U̷̧̨̢̜̹̥̜͚̗̝͓̘͈̪̩̖̲̎͊̂̑́̓̈́͠T̷͓̠̯̬̗̩̟̣̃̔͐͊̎͝͝Ẽ̶̹̤͚̽͛͗͆̿̍̀͂̏͠ = Enochian english hope this helps
MPR121 is very nice, but it's $1.59 on LCSC and I'd need 4 of them which would add up to over $6. The analog multiplexer is $0.10-$0.20, and I need 5 of them, so it's
My understanding is that those analog pins are capactive touch , but why didnt you just use the same digital pin matrix with diodes as seen on the original ? No need for those multiplxers ? But your approach is quite neat , how many gpio did u connect to each mux ic ?
when you are doing tracks it's pronounced 'rooting' when you are cutting grooves it's the one that rhymes with 'out', it's the same as a road is a route (root) Americans will tell you otherwise, one of their famous songs is route 66 which they pronounce root, yet everything else is r-out i did a vid on this (router router)

Routing, it's definitely pronounced Routing. Great project, glad to see it coming together.
no, it is pronounced routing, for sure ...🙃
I don’t wanna sound contrarian but I do think it’s pronounced “routing” actually

Superb! I loved my spectrum, still got it in fact. I love the esp32 now so will be keen to get one of these 😎

Great project! Love seeing that the keyboard is working out. Do you mind sharing with the multiplex chip is?
Route like fruit = British english
Route like shout = American english
Route like R̷̲̩͚̰̃͑͆O̸̙̠̹͙͖̲̠̦̤͐͑͒̍́͊͊̔̋͝͝U̷̧̨̢̜̹̥̜͚̗̝͓̘͈̪̩̖̲̎͊̂̑́̓̈́͠T̷͓̠̯̬̗̩̟̣̃̔͐͊̎͝͝Ẽ̶̹̤͚̽͛͗͆̿̍̀͂̏͠ = Enochian english

Great engineering thinking!
genial! muy bien hecho!
Definitely roUting; rOOting means something very different in australia :P
Genius!
why not use an i2c touch sensor with 10 channels? mpr121 also cheap as chips
MPR121 is very nice, but it's $1.59 on LCSC and I'd need 4 of them which would add up to over $6. The analog multiplexer is $0.10-$0.20, and I need 5 of them, so it's
I remember the bbc had a 2 key “rollover”.
Are you putting the Shift key on separate multiplexer pin i.e. outside the keyboard matrix?
There is no keyboard matrix at all now. Every key is independent.
My understanding is that those analog pins are capactive touch , but why didnt you just use the same digital pin matrix with diodes as seen on the original ? No need for those multiplxers ?
But your approach is quite neat , how many gpio did u connect to each mux ic ?
I just realized, you don't actually have any physical keys , lol , so capactive it is !!
Hey, whats up chris
when you are doing tracks it's pronounced 'rooting' when you are cutting grooves it's the one that rhymes with 'out', it's the same as a road is a route (root)
Americans will tell you otherwise, one of their famous songs is route 66 which they pronounce root, yet everything else is r-out
i did a vid on this (router router)
Does PcbWay have small switches that would allow me to make a small qwerty keyboard ? (almost as small as smartphone keyboard)
I would say routing as [ruːtɪŋ], as routing [raʊtɪŋ] means to chase someone away. At least in British English. American English might be different.
Nice project!
How did you made your colorful PCB? Is it printed on top or just a sticker?
Why haven't you called it ESPectrum?
I am also interested in how the PCB colours are made? :)
Full color silk screen printing - it's amazing!
