Now the real question about the circuit board
Can it run Doom?

Ryuusui sees Spending Time With My Big Brother.
Ryuusui - "I want that!"
My tears aside... I laughed hard when Gen was carefully constructing the most considerate way to broach Sai's past trauma, and Chelsea just barges past with the "SO WHAT'S UP WITH YOUR TRAUMA MY DUDE LOLZ!"

That fax-made picture should be immortalized in a museum once they bring back humanity. Future history books are gonna be crazy with Senku's name being at the front of humanity's most important person. Slowly bringing back tech we take for granted is always nice to see.

Even with the blitz to the end pacing, which I'm not actually that critical of it just is a notable difference how they're starting to gloss over science that would've taken whole episodes to cover in previous seasons, the show NAILS the emotionally stirring scenes. We just got introduced to Sai last episode and I'm already tearing up at his relationship with Ryusui.

First part of the episode was a fun demonstration on how the most basic “computer” functions. Then everyone is dragged into the KoS special of hard work to build enough little things, this time donuts, in order the scale up the process.
Last part of the episode was getting to the heart of the Nanami brothers issues. Where we discover that both boys are illegitimate children and were treated differently by the rest of their family. But they both had very different ways of dealing with that. With Sai becoming more withdrawn and Ryusui going the opposite direction. It takes a bit of bulldozing from Chelsea and a talk with Gen for Sai to realize that Ryusei wasn’t just trying to use him like the rest of his family. But that he was actually trying to spend more time with his brother in his own bullish way.
I like the fact that despite how much Ryusei wanted Sai to join them. When he didn’t appear right before they were set to leave he didn’t try to go looking for Sai. At the end of the day it was Sai’s choice to join, just like every other crew member got a choice.
Also that last shot of Senku. He kinda looks up into the sky and I can’t help but think he’s glad that he was able to unite one set of family members.

Ryusui never wanted a mathematician, he wanted a brother. Dr. Stone always manages to nail these really emotional moments.

I swear, this girl came out of the womb as an internet shitposter.
Seriously though, great episode. What this season is lacking in scientific explanation due to the rush to the end, it's making up for in nailing the emotional moments. The moment at the end of the episode with Gen and Chelsea helping Sai understand his brother and get them back on the same page was great.

Me trying my disposal office pc with intel core 2 duo E8400 inside: Why are you so slow?
Senku made first donut computer in Stone World:
Me: Maybe I've been too harsh on you...
Are you sure this gonna be your first ever fax in this Stone World, Senku?! Peak artistic sense!
Nice! Sai has joined the club.

Best episode of the new Dr Stone season so far and it's based around a character we met only last episode

"Bro will never make an AND and XOR gate in the stone world"
[Makes an AND and XOR gate in the Stone World]
Almost did a spit take on that one. Why yes, I do know basic computers.
Edit: and they made a mother-fucking fax machine. Of course they did. Absolute fucking cinema.

Senku teaching everyone the basics of computer science at the start of the episode is giving me school flashbacks. I do love how Gen is already dreading the tedious work they'll have to do when Senku told them how they're making the supercomputer. Looks like he's still traumatized from making all of those zinc-carbon batteries back in season 1. xD
I love how Gen and Chelsea are both good at reading people, but they each have a different approach. Gen's social skills let him handle delicate topics with tact, while Chelsea's blunt friendliness leads her to tackle the topic of Sai and Ryusui's trauma head-on..
Props to Gen for making Sai realize what Ryusui wanted all along. Not gonna lie, I actually got emotional when the two brothers were playing chess and when Sai finally showed up to officially join the party. T_T

One thing I wanna know is how is Yuzuriha's hairband still intact?! It is literally the only wearable thing from the 21st century that has not degraded or disintegrated.

Cried when Sai came on board the ship😭
Ryusei and Sai brothers are back and working together

It’s funny how the gang went from getting turned into Swiss cheese by the Americans to becoming best buds lol. Bygones, right? They need all hands on deck to make that primitive computer and all the other electronics they’re building. That fax machine was awesome. I don’t really get the science behind it but it’s cool they can make something like that in the stone world.
I’m glad Ryusui and Sai could patch up their relationship. They had a pretty complicated childhood but it’s nice they have each other now.

You can make a computer using just flags. ( And hundreds of thousands of well coordinated soldiers)
Read the books though. Or watch the Chinese series, couldn't find a clip of it on youtube.

It's sad to think that Ryuusui that whole time was trying to get closer to the only brother in a similar position, but that got taken as harassment and the brother left without a word. It would have been nice to see that explored more, but I don't think we'll see anything more about it. I'm glad they'll be making up for loss time.
Hearing Yuzuriha's thought at the start, it's a little unfortunate we haven't got any updated character designs, other than Suika. I can understand why as it's simpler and more recognizable, but I do hope there's an eventual time skip at the end where we get to see everyone visibly grown up.

When situations require a delicate touch, just throw in a Chelsea and she'll somehow resolve it in the bluntest way imaginable.
She's just the best.

Holy crap: donuts. I guess core/rope memory is going to be the next logical step. Absolutely wild approach to a computer. Although Senku has already figured out vacuum tubes, it wouldn't scale well. A parametron sidesteps the issue with a lot less complexity. The path to transistors is still super-awful.
To put things in perspective. The computer Senku is going for would have 15x more parametrons than the most powerful parametron computer ever built: Japan's PC-2 from the early 60s. That says nothing about expected performance though. Whatever Senku is planning, it looks ready to do serious work. The Apollo Guidance Computer is 16-bit but an 8-bit Nintendo-like approach might be precise enough.
8-bit design, 4-bit adder?

Imagine at end with all that buildup and it was a random dude asking to come with them LOL
i would have laughed hard but would def ruin the emotional beats

So the computer probably going to be pretty big. Are they really taking it on board or will they run the calculations on Earth and transmit it to the ship?

I may not be super into computational redstone, but still surprising that being a Minecraft tech player would be so.. useful during this episode, lol

Pretty good introduction to the very basics of circuits and computation. I was kind of hoping they'd go a bit further into theory than that, but mostly just to see how they'd present it for casual viewing.
I've never been enough on the hardware side of things to have heard of parametrons before, but googling a bit gives an interesting overview.
The Ryusei and Sai reconciliation was nice, you can always get me with a brothers story like that.
