That's more a programmable watch than a DIY one :-)

I build mine from scratch, including the PCB and a 3D printed case.

For sure, that's not at all the same level of customability, programmability, capacity, nor quality. But It is really a DIY one.

Easy: anyone who cannot submit to the law of a country should not go there.

Spacetime curvature.

Like if you dropped the earth on a giant sheet, it would stretch the sheet more than what the moon would have.

Me and my children follow Guirec since its first adventures with Monique when he first sailed through the Northwest Passage.

He later crossed the Atlantic by rowing, back and forth, and this year he did the Vendée Globe race.

This guy's determination and dedication is insane.

It's not so much his actions, it's just that giving money to someone who gives a Nazi salute is a problem for me.

As a French, I had previously no opinion on Tesla and I could have bought one. I saw it as a geeky, high-end stuff.

But those days I see owning a Tesla as activism (probably unconsciously). I would preferably buy any another brand rather than being flagged as an Elon-fan in my neighborhood.

Also, I'm not sure that those two affirmations are equivalent:

  ~∀x  (~IsAHatOfMine(x) ∨  Green(x))

   ∃x ~(~IsAHatOfMine(x) ∨  Green(x))

I agree for A), by why D) ?

Moving to another country is a good idea as an individual. However, for a nation as a whole, nothing is easier but building rich people: Leave, and somebody else will take your place.

We have a law that somehow covers this in France. It is permitted to use a metal detector for leisure provided that it is not a search for archaeological objects.

However, this law can be interpreted from many angles, as it is difficult to define what is archaeological or not. There are certain associations which defend “leisure detection” as long as it is not located on a registered archaeological or historical site. But their point of view is not shared by archaeologists, who consider that any place can be considered an archaeological site, relegating leisure detection to fine sandy beaches.

In this context, case law says that there are no completely accidental archaeological discoveries with a metal detector.

Nice tip. Thanks for sharing. I'll probably try this by making a cheap one with one of my kids' microbits. This seems like the perfect board for doing this.

I use Clever cloud too for application prototyping when I have to go fast, and for my side projects.

Very reliable, I've never had a problem with it.
