I used to graduate at an institute having physicists as well as chemists, I gues it was no coincidence that only physicists operated with HF, one chemist told me that no chemist in their right mind would touch it

That's not quite accurate (but close enough). We had HF in the chem lab. It lived in a dedicated metal box with a massive neon warning label and a padlock. It's notable in comparison that all the deadly organics lived together in an unlocked cupboard (vented OFC). I think the only thing I ever saw treated as more of a pariah than HF were radioactive isotopes. Those generally get an entire dedicated room with restrict…

As usual for particularly nasty crap, Derek Lowe has written amusingly about why he won't work with it[1].

HF is routinely used in analytical labs; it's standard to microwave HF solutions for ICP digestions. It's not even the most hazardous reagent in my lab right now. Now, perhaps this chemist meant that no chemist in their right mind would physically touch HF--in that case, I agree completely!

AFAIK they're talking about anhydrous HF gas, not solutions of it. That sounds substantially less fun to work with. It's used to clean CVD chambers.

In my journey to make pcb’s at home I decided to stop once I almost gassed myself and shifted instead to buying gpus

I visited a pcb making factory once. Left with an appreciation for the amount of work needed for 80-layer pcbs, and knowing I would not want to deal with making them myself.

my goal was simple 2 sided pcbs, machined traces because i wanted to avoid chemical etching, but when it comes to via's chemicals are really the only way. The chemcials needed for plating via's are very toxic. my current thinking to avoid the really nasty ones is to try conductive ink (probably pretty bad too) but it maybe would work to coat the fr4 material and then allow a copper plating to take... really it's a fun process machining and laser the soldier mask.

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

Content creation was always about content. If you can make something special and engaging, audience will come.

> If you can make something special and engaging

... and sufficiently interesting to more than a very small group of persons.

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.

I rewatch that every year as a reminder of what we're capable of. Great video.

Yep, me too. Still feels magical after all these years.

Good video, informative, easy to digest. You should start your own company, perhaps as in the form of an employee-owned entity or using Kickstarter to create an all-in-one RAM Fab kit that can be sold online. I'm sure the maker community may consider buying it.

Technologies that were considered "high-tech" 20-30 years ago are now accessible to regular people. Making DRAM. I remember a video recently of a guy making his own floppy disks. Next I expect people to manufacture integrated circuits that have been discontinued. Like the Z80

Makes me wonder if in the far future it will be ever possible to do something crazy like 7nm processes at home

The Titanic is pretty old. Could you build that in your backyard? The scale of the equipment required has drastically increased over time.
