I saw this video yesterday and considered posting it, but I wasn’t sure if it was appropriate for HN.
This channel has another video where it shows how the clean room lab is created starting from a basic backyard shed, and that was truly astounding. The positive pressure to keep the number of particles low in someone’s backyard is almost mystical to me.
You’re not sure if someone building a RAM clean room in a shed is appropriate for HackerNews, literally “news for nerds”? A dictionary purchase may be warranted
I think he plans to go far beyond just making RAM in that clean room. This is pure speculation, but I suspect the goal of that channel is to just make doom from scratch.
Given that the shed in this guy’s backyard is already approaching the entire national technological output of any country in the 1970s I think he may get there.
I think if it's interesting to you then it's worth posting, and letting the voting system do it's thing. I only rarely post because by the time I've seen something it's usually already been posted
Recently I saw a post about Bonsai trees on the front page. Making your own RAM is 100% more relevant to HN than quite a few posts I see on the main page.
Backyard semiconductor production is pretty similar to backyard barbecue. Lots of heating, smoking (diffusion), injecting (ion implant), and layering..
The graphs towards the end were discharge curves for a single transistor/capacitor cell out of only 16 present, if I understood correctly? So "enough cells to count as memory" and "addressing logic" are definitely future work (it looked like he wanted to characterize what the refresh cycle would have to look like before actually building more.) I was kind of surprised that the "use a microscope as a photolithography projector" approach worked at all, it will be interesting to see how that scales up...

I only buy free-range artisanal DRAM at the DRAM farmer's market.

Agree with the sentiment, but “news for nerds” is Slashdot.
Slashdot still exists?
Well, “exists” is a pretty broad spectrum.
Yeah but it's a YouTube video. Those tend not to do super well on the front page.
If you haven't seen this one, I highly recommend it:
Indistinguishable From Magic: Manufacturing Modern Computer Chips
https://www.youtube.com/watch?v=NGFhc8R_uO4&t=2070s
It's quite old but I think there is no modern version of it.
I've tried posting to HN a few times but it hasn't gained traction for some reason, but I find it absolutely mind blowing.

Tbh this is exactly the sort of thing I'd come here to see

This is incredible! 1100 degrees in your backyard shed! And the video explains it well too
I wasn't expecting what the inside of the shed would be like!
Nobody tell openai about this, they’ll buy up all his stock
This guy is proof that newcomers to YouTube can still succeed, if they find the right niche.
Mom: We have RAM at home!
RAM at home:
Subscribed. Genuinely looking forward to what this gent gets up to.
Spoiler: we never actually get to see the RAM tested

2 bytes of memory ought to be enough for anyone!
