Lead-based solder is preferred for high-reliability electronics (space, nuclear, military, etc.) because it’s easier to rework, easier to verify by visual inspection, and it’s not vulnerable to tin whiskers.
I’m an electrical engineer living in Los Angeles, CA.
Lead-based solder is preferred for high-reliability electronics (space, nuclear, military, etc.) because it’s easier to rework, easier to verify by visual inspection, and it’s not vulnerable to tin whiskers.
Here’s the relevant safety guides from Stanford and MIT.
In short, if you do a lot of soldering, there are long-term occupational hazards from both lead oxides and rosin. Both guides agree that the main hazards are the fumes (workstation should have a fume extractor or suitable filter) and residue on your hands (wash hands with soap and water before eating).
I couldn’t find any numbers on how much material is removed by washing, but every reference emphasized that soap and water are vitally important.
IF YOU DON’T RULE AND STONE, YOU AIN’T COMING HOME!
“WAAAAAAAAAGGH!” is what the 10-foot monster yells while charging at you.
Does that require admin access? It wasn’t their machine, it was one the school provided for the auditorium.

I saw that happen once in a big presentation.
There was a team of students presenting their work to ~200 people. Right in the middle, a pop-up says updates are finished and the computer needs to restart. It has a helpful 60-second countdown, but “cancel” is grayed out, so all they can do is watch.
I was only in the audience and I still have nightmares.
Bicycles are heresy confirmed.
Not the hero we need, but the hero we deserve.
WE’Z ZOGGIN’ WORKIN’ ON IT. WAAAAAAAAAAAGH!!!
We are the Cube Rule. Lower your shields and surrender your ships. We will add your food’s biological and technological distinctiveness to our own. Your food categories will adapt to service us. Resistance is futile.
I’ve had great luck running HomeAssistant on an R.Pi with the “HUSBZB-1” USB dongle. Zigbee support is perfect so far. Z-Wave required installation of an additional tool, but also working just fine.
Doesn’t the ESP32 module this project is using require the same thing?
It works for now on x86-64, yes. For now. As always, we are one “think of the children” crisis away from lobbyists taking that option away.
It’s not for you, it’s for them. Secure boot means it only runs their operating system, not yours. Trusted enclave means it secures their DRM-ware from tampering by the user who owns the PC.
This is a quote from The Onion’s endorsement of Joe Biden for president, which was posted October 3, because it’s The Onion.
I went to the LA showing of “To The Journey”, a crowdfunded documentary about the making of Star Trek: Voyager.
Several cast and crew were there, including Rick Berman, Robert Picardo, Tim Russ, and Garrett Wang.
