If you are in need of a lesson on just how much things have changed in the last 60 years, an anecdote from my childhood might suffice. My grandfather was …read more Continue reading Mining and Refining: Lead, Silver, and Zinc
When it comes to renewable energy, there are many great sources. Whether it’s solar, wind, or something else, though, we need a lot of it. Factories around the globe are …read more Continue reading Dead Solar Panels Are The Hottest New Recyclables
After five years of research, Colgate-Palmolive recently revealed Australia’s first recyclable toothpaste tube. Why is this exciting? They are eager to share the design with the rest of the toothpaste …read more Continue reading You Can’t Put the Toothpaste Back In the Tube, But It Used to Be Easier
Any video that starts with a phase diagram has instantly earned our attention. Admittedly, we have a pretty low bar for that kind of stuff, but eye candy aside, [Robin …read more Continue reading Make Your Desoldering Easier by Minding Your Own Bismuth
I published the following diary on isc.sans.edu: “Sensitive Data Shared with Cloud Services“: Yesterday was the data protection day in Europe. I was not on duty so I’m writing this quick diary a bit late. Back in 2020, the Nitro PDF service suffered from a data breach that impacted many

Scientists found a surprising amount of lead in a glacier. They were studying atmospheric pollution by sampling ice cores taken from Alpine glaciers. The surprising part is that they found more lead in strata from the late 13th century than they had in those deposited at the height of the …read more
Everyone one of us is likely aware of what lead — as in the metal — is. Having a somewhat dull, metallic gray appearance, it occupies atomic number 82 in the periodic table and is among the most dense materials known to humankind. Lead’s low melting point and malleability even …read more

For most of the history of industrial electronics, solder has been pretty boring. Mix some lead with a little tin, figure out how to wrap it around a thread of rosin, and that’s pretty much it. Sure, flux formulations changed a bit, the ratio of lead to tin was tweaked …read more
Did you ever stop to think how unlikely the discovery of soldering is? It’s hard to imagine what sequence of events led to it; after all, metals heated to just the right temperature while applying an alloy of lead and tin in the right proportions in the presence of a proper fluxing agent doesn’t seem like something that would happen by accident.
Luckily, [Chris] at Clickspring is currently in the business of recreating the tools and technologies that would have been used in ancient times, and he’s made a wonderful video on precision soft soldering the old-fashioned way. The video …read more
When that fateful morning comes that your car no longer roars to life with a quick twist of the key, but rather groans its displeasure at the sad state of your ride’s electrical system, your course is clear: you need a new battery. Whether you do it yourself or – perish the thought – farm out the job to someone else, the end result is the same. You get a spanking new lead-acid battery, and the old one is whisked away to be ground up and turned into a new battery in a nearly perfect closed loop system.
Contrast this …read more
