When my geologist father passed on, I discovered that I had not learned as much about geology as I thought by osmosis! I have been waiting for an app like this its actually pretty hard to track down what a particular outcrop. Thanks - Gneiss work!

As far as I can tell, this paper (in which Einstein solves a decades old question about Crookes Radiometers) has never been available in English before! Einstein’s work became public domain on 1st January 2026, which meant that I could finally release this translation that I did during my PhD in 2019! Its a fairly easy read and demonstrates the great scientist's laser sharp mind.I have a blog...
If I understand what you are saying, it might be that your phone had a better camera than your ipad? The depth of field and atmospheric lens effects aren't really what you want - a pinhole lens like old phones (and my flir) works better since blur is the enemy.
... and the audience is too mature to mention that the internet stole the acronym Computer Numerical Control, so its often shortened to Numerical Control to make it safe to search?
If you are doing pool pcb manufacture - think about getting your design rules as a template in KiCAD (you could talk to KiCAD services corporation about how to do that) or Altium. This would help people designing to avoid getting to a finished pcb then discovering that you have a rule about no route through pads or whatever.
OK, Its a cool video, and wish there was more joined up thinking about keeping sovereign control of designs/manufacture - but the concept isn't new. I know the UK better, but 24 hour pcbs are a thing, we have
https://www.pcbtrain.co.uk (which might outsource to china anyway) but I usually prefer
https://www.eurocircuits.com/ which builds in Poland. There are plenty more CEMs
Sadly neither really compete on price with jlcpcb and despite a hemisphere of delivery advantage jlcpcb can be quicker! I once got in a discussion with a Project Manager about whether the design was worth keeping some level of traceability for ~$50... he just wanted it cheaper.
I have used local LLMs (Qwen27B) to generate SCAD versions of components. I got there eventually - it took a bit of cajoling, but have printed that component and confirmed that it fit the parts and the output was properly parameterized in a way that Solidworks wasn't.
As an experienced hardware designer I am never... confidently wrong!

Really?! Making this project must have taken tens or hundreds of hours - if they are proud of the work, why not show it off? The video looks like it wasn't faked.
Did nobody look at the image after they generated it? If they live in a bedsit and don't have a nice windowsill, they could easily generate the background and if the product is vaporware they could drop a rendering over the top - I think that might actually be easier than training an AI on your product... I'll be grumpy at clouds next!
Is no one going to mention that the first picture is AI generated tosh? I understand that generating a picture is easier than taking a nice picture, in a nice place with a a nice camera - but the back row of the board is all white and the second row.. sort of disappears!
