I thought myopia has a significant environmental component, eg doing most of our development indoors instead of outside in bright sunlight?

Equally intriguing, I've noticed that most fridges have the hinge on the right.

Not sure why people keep making this argument. If I'm obscenely rich and don't want to follow the rules, it's at least an order of magnitude cheaper and easier to have something on earth than mars. Buy a country or two, or se

What are all those Unknown JSC Vimpel objects in that one well-defined orbit between LEO and geostationary?

Yes. Live in one of those areas and "radon mitigation systems" are common. There is a sealed lid that goes over your sump pump cover, and a fan constantly pulls air from it, which goes up a tube on the side of your house and empti

Can it even be cast? It looks like this would be really difficult to get to come out of the mold. Unless you go investment casting over die casting.

Well I guess we know what happened to those failed chips from Curiousmarc's broken DRO. Maybe I missed it, but what actually makes it wear out? And why does it last so much longer than flash/eeprom?

On the other side of this you have something like the Runit Dome, which is a nuclear test crater in the Pacific which they filed in with radioactive debris and covered in concrete. It is starting to leak from rising sea levels. But when peo

These are the best kind of posts, where there's something I've never even heard of before. I never knew 'oiling the seas' was a thing, or that it (apparently?) works.

Seems like the tough part of this is access to the magnetizing machine. I wonder if the same effect could be achieved by placing tiny off the shelf magnets[0] in the molded part instead? [0] https://www.kjmagnetics.com/prodde

Would be really cool to read a whole CD this way. Actually, that wouldn't sound any different. You could read an LP though.

We need this for the Usagi Electric vacuum tube computer.

Wow this was not a cheap project! Thanks Ebay collectors. Also probably the only time I'd have gone for an LCD over a VFD. If you're running a multi-year long compile, it'll probably be burned in to hell by the end.

I find it really funny that the newer TI stuff has Python now too. But they just stuck an extra ARM microcontroller on board (which is more powerful than the main ez80 CPU). If it ain't broke, support it for 32 years!

Is the Ti-84 still the gold standard for school calculators? I had an nSpire when I was in school - much higher resolution screen - but most everyone else had a ti-84 or 89. The nSpire was powerful enough to have hacks for it to run full Ga

FreeCAD. Or, if it's simple enough, I write it by hand and use Python to do loops. I've got a handful of Python scripts that can mill holes, make square pockets, write text in a vector font, etc.

Raise and lower your orbit, I guess. Any unbalanced force on something in orbit will do one of the two.

If anything, if someone's wearing Airpods, I'm going to assume they can't hear anything I'm saying. "oh no he's wearing airpods" is a meme for a reason.

The sensor for the Pinecil / TS100 seems to be located fully behind the tip though: https://web.archive.org/web/20221110163337/http://www.minids...

Thanks for the response! If true, this would make the experience more like a Metcal then. Very good iron. You must have your thermistor/thermocouple very close / inside the tip itself then, no? No doubts then on the tip quality -

Well done! I'm mostly a TS100 user, so I'm looking at it from that angle. Why no boost button (unless I missed it)? That's the one on-iron UI feature I'd be missing - very useful for GND planes. I'm guessing its not

Landfills. Theoceancleanup's own figure is that there is 100,000 tonnes of plastic. This one [0] landfill in Ohio gets 2 million tonnes each year. That's out of ~250 million tonnes produced by the US each year [1]. So it seems the

I've been gently bit by a small Tesla coil before (100s of kHz but lower frequency than AM). There is absolutely no 'electrical' pain to speak of - it is nothing like getting a static shock or touching line voltage. However,

Ok, but that's supposed to be the reason we have scientific institutions in the first place. If I want to prove the earth is a globe and measure its diameter, all I need are a couple sticks and a tape measure. If I want to know if a dr

This takes me back to one of my first hacker projects. We were going on a family road trip and I had found an old marine GPS receiver. The manual it came with showed a special cable for RS232, but I didn't have it and so drilled a hole
