Hey, nica project! Can you add the pcb schematics and the Fusion 360 source files for the enclosure? Thanks!

I don't want a new travel agent, I just want to go home

Col! Can you share it?

Silane is like Methane, but with Silicon instead of Carbon (SiH4). Thanks god for doping was used Phosphine (PH3) and not Phosgene (COCl2), both are nasty, but the second is more. Plus I don't know how much is used, since nowadays doping is typically done by ion implantation rather than gas diffusion

yes... the only advantage of Hydrogen I can imagine is the abundance, for the rest I see only downsides. Helium is relatively abundant and technically renewable: it's a byproduct of gas extraction, since it's continuously produced by the alpha-nuclear decay inside the earth. Of course doesn't mean the offer is adequate with the market request, especially after the Hormuz crisis

The claim that traditional electronics can't work at deep cryogenic temperatures is vastly exaggerated. Of course you can't take something as complex as a modern microprocessor and hope it works at 4K, but modern fully-depleted MOSFETs typically works. Their electrical characteristic will be different, so a tailored design it's often needed

I seriously don't get it. At my time in university, ALL the exams were oral. And most had one or two written parts before (one even three, the professor called it written-for-the-oral). Sure, the orals took two days for the big exams at the beginning, still, professors and their assistants managed to offer six sessions per year.

Maybe someonw can explain me, but I never understood the appeal of GPIB for modern instruments (legacy instruments are of course "excused"). Electrically is a terrible interface that introduces ground loops with the control computer. Speed are laughable and it requires exensive and exotic adapters with complex sw stack (I wish this projects good success, it's needed!). Ethernet in comparison tick all my boxes. It's electrically decoupled by default (just use UTP cables), crazy cheap, very fast and with sane sw stack thanks to vxi-11. You can even bypass visa if you wish and open a plain TCP socket, no need for any library. What am I missing?

Not at all, it depends on the residence permit. With a C permit you can buy and rent properties, while with B you can buy only your own home

God, I hate so much these videos. My son son used to ask for these when he was younger, they were so bad...
