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

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

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.

Spoiler: we never actually get to see the RAM tested

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.

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

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...
