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

I saw this video yesterday and considered posting it, but I wasn’t sure if it was appropriate for HN.<p>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.

So, I get that we charge the capacitor up, and that it leaks so we must recharge it periodically. I don't get two things:<p>1. How is the value read? Is it reading the leak?<p>2. How is recharging done? I guess the leak itself (assuming my guess in 1. holds) could provide charge for some logic that checks "if has charge then recharge else nop".<p>I still don't really get transistors :P, but this was cool.

We need to be able to make semiconductors at home for computing freedom to be preserved the way the world is going.

I'm not sure this is what they meant when they said they wanted to bring manufacturing back to the USA lol

This guy is proof that newcomers to YouTube can still succeed, if they find the right niche.

Backyard semiconductor production is pretty similar to backyard barbecue. Lots of heating, smoking (diffusion), injecting (ion implant), and layering..

I wasn't expecting what the inside of the shed would be like!

This is incredible! 1100 degrees in your backyard shed! And the video explains it well too

Nobody tell openai about this, they’ll buy up all his stock

Spoiler: we never actually get to see the RAM tested
