It's a special case, but in times like this I think about the antique cars. There are still Model T owners out there driving around with oil-soaked cotton brakes. That's the same material my pants are made out of. And it's

Oh yeah, the books are impressive in their own right. However many items you think they sell looking at the website, the book reveals you were a couple orders of magnitudes off. 1000+ bible-thin pages of well laid out tables and product pho

Maybe, but I never seem to have trouble searching for even further incomprehensible part numbers on other items. Give me a DigiKey part number like "WM7610CT-ND" and google finds it first thing. Digikey is also the first result fo

It's ok most of the time, but it's not like they sell McMaster branded stuff in McMaster packaging. They are a supplier, and might want to obfuscate to keep you from buying direct from the actual manufacturers. On the other hand,

Actually, I'm pretty sure I've never seen a McMaster link in any search engine. Even if you google a direct McMaster part number, like "91251A449", McMaster will not be among the results. While the url to that product is

I'm going to go against the crowd and say that I prefer DigiKey and Mouser's sites over McMaster. The filter/apply pattern they use when trying to narrow things down is a lot quicker than waiting for Mcmaster's auto upda

From when I was briefly working with "personal" resin printers (elegoo, anycubic, etc): - In terms of strength, print orientation doesn't really matter. - The z height is pretty much the only thing that affects print time sin

In the old days you needed to be a lot more cautious with sharp corners. If you print into a sharp corner, the hotend has to decelerate to a stop and then accelerate in the new direction. During this time, a little extra plastic will leak o

I've heard that one of the things they wanted the shuttle to do was launch, capture a spacecraft in polar orbit, and land at the launch site within a single orbit . Some say it was so they could secretly grab a Soviet satellite right

In general, I find it easier to desolder and replace surface mounted parts. With those, you just have to hit it with some hot air, it melts all the solder at once, and lifts right away. The chips are small, so it's not too bad to heat

How big is big? You can still get used FE-5680A rubidiums on Ebay for a few hundred. They are about the size of a small book and need ~20 watts. Not sure how good/useful/not broken they are since I've never had one, but over

Reminds me of those times I work with temperature sensors which report in eighths of a degree. 3 decimal places to give less than one decimal place of precision. You can round, but somehow that doesn't feel right.

I can understand not wanting to puncture a pouch style lithium-ion cell (what most people call LiPo), but then why not go for an 18650 or 14500 battery? Same lithium ion chemistry packaged into a more traditional and durable metal can. Alth

Most routers (including humans) haven't even figured out that you can run traces in more than just 8 directions :) I quite like autorouted boards in TopoR for this reason, but it's hardly cutting edge; been around for decades. I h

A lot of deserved criticism in the comments here tonight, but more generally, I have to ask - what's the deal with all these code/text to CAD/PCB things? There's a half dozen of them in any category, they are all differe

Earth's atmosphere is 5.15×10^18 kg and at atmospheric pressure density is 1.293 kg m−3. The whole thing would be more like 4 billion billion cubic meters. So a billion AC units could have the whole thing cleaned up in just 200 years.

What does it even mean for a TV to be energy efficient? A TV's job is to convert electricity into... light, I guess? It's not light like a light bulb, nor would you want it to be. You wouldn't light your home with TVs. So is

Most of the things I work on are "make this fit onto that like this". There's not that much information contained in that sentence, it's contained in the 2 objects I was just handed. Sometimes we have drawings for that s

You're right, but I think we have a long way to go. Even our best CAD packages today don't work nearly as well as advertised. I dread to think what Dassault or Autodesk would charge per seat for something that could do the above!

Feels a bit like being on a call with someone at the hardware store, about something that you both don't know the name for. Maybe the person on the other end is confused, or maybe you aren't describing it all that well. Isn't

Let's just hope they are lying. Where do you even get radon gas? The most stable isotope has a half life of just 3.8 days. Unless they mean they built on a place with unfortunate geology or have a large stockpile of radium around.

I have a similar accent and we would say it like "furrah-man". For me, the "ah" becomes a lot weaker going into the "m", so I can easily see it. I'm also intrigued by the idea that it was a flub which he r

I've been down this road before. The ASIC in the Milwaukee pack is known as an "analog front end". Since you can't wire cells directly up to the pins of your MCU, you have a chip to handle that stuff for you. It will let
