I don’t disagree with you. My only point is, once you’ve crimped a connector, do not add solder. It will make the reliability worse, not better.

I didn't see it mentioned in the article, but please don't add solder to crimped connectors "to be extra secure" even though it's common advice in hobbyist circles. Unless you're using PTFE or similar insulatio

Those are the bare minimum in my opinion, and ok for your toolbag. But the 2 Chinese models on the bottom of the page with proper dies (be sure to get the right dies for your connectors) are so much better. If you zoom in to the images, you

The second version of Apple wireless keyboard is closer than the newer ones, to my tastes anyway. It's softer than current MacBook keyboards but has slightly more travel so I'm not sure it's what you're looking for.

I've seen it recently in Western Europe in British import shops.

That's correct. It's easy, especially in retrospect, to brainstorm every possible feature to make something like this more reliable, but it doesn't take much extra mass, power or development time to end up as a cancelled proj

It doesn't seem to be advertised well because I've never met anyone in Europe who is aware, but there are usually a few European stops on the Monster Jam tour. Looks like only 1 in Sweden next year.[1] [1] https://www.mo

These dispensers are specifically called out along with "26% of spare parts" in a DoD audit. I assume the auditors know what they are doing, are well aware of the fact that qualification and traceability costs money, and factor th

This is overselling the variety a lot. Hot and cold drinks including a couple of types of soup (sold only in winter) are everywhere. Cigarette vending machines are pretty common (usually located in front a tobacco shop). Ice cream and small

I converted a Logitech mx2 mouse from micro-usb to usb-c. When doing so I confirmed and am 100% certain that the data lines of usb are not connected on this mouse (only ground and 5V are connected for charging). The traces to the micro-usb

On the other hand it seems like a miracle that wifi works pretty seamlessly globally, and there are no countries where you have to pay to use a proprietary service instead.

A system-wide mute button and a system-wide setting to say "this is the only microphone I want to use and when it's muted I don't want another mic to be used" would be nice. Wired headphones often have a physical mute sw

That's trivial for a machinist to check before starting the milling operation though.

It would be surprising to me, considering this is one of several actions done to make iPhones easier, not more difficult, to repair.

I have been a huge advocate of the pinecil and haven't used anything else in years. It's just so easy to grab my pinecil and temporarily use my laptop's power supply for the iron, or use a mobile battery, instead of moving my

I did mention it’s become a lot better. These are just minor annoyances.

Recently windows has become much better for things a linux or macOS user takes for granted, like using ssh (a quick google search tells you how to install it using powershell), but is missing a lot of features. Two recent examples for me ar

When I got an ultra wide monitor I also noticed this for the first time on the macOS circular red X button, when wearing glasses. I guess a wide monitor has you looking at things off-axis more. It is really remarkable how much you can make

Find my is really a killer feature. When AirTags were first released, there was a bunch of media on potential use by stalkers and it seems like Apple hasn’t advertised how airtags (and findmy with devices) work at all since then. Most peopl

GPS-denied navigation is the search term. It works well enough for driving through a tunnel, because eventually you get a known location to correct previous estimates. For a fully-indoor environment it's very difficult to get good resu

Glad you mentioned PLCs. I keep seeing more and more young engineers reinventing wheels with raspberry pi and arduinos, especially for things like test jigs. It’s almost like PLCs are a secret in some industries.

What is it with media that attributes everything to "Japan"? Here we have a private company trying out a robot made by a much smaller private company, in Japan. It's not like the government of Japan is rolling out gundams acr

I think up to jerk is intuitive, even if the term isn't well-known. Most people have no problem figuring out how to ease-up on brakes in a car, and a hobbyist can usually figure out how to make things smoother when ramping up or down a

I've found even the cheap stuff to be long-lasting if you disassemble it before moving it. Carrying or pushing shelves in a way that turns them into a parallelogram is what damages them.
