Collaborate Disseminate
There was a time when all major corporations maintained film production departments to crank out public relations pieces, and the electronic industry was no exception. Indeed, in the sea-change years …read more Continue reading Retrotechtacular: Manufacturing Philco Germanium Transistors
If you think polyimide-based flexible PCBs are cool, wait until you get a load of what polymerized liquid metal networks can do.
Seems like [CNLohr] has some pretty cool friends, and he recently spent some time with a couple of them who are working with poly LMNs and finding out …read more

Most hackers are rankled by those “Warranty Void If Broken” seals on the sides of new test equipment. Even if they’re illegal, they at least put the thought in your head that the space inside your new gear is off-limits, and that prevents you from taking a look at what’s inside. Simply unacceptable.
[Shahriar] has no fear of such labels and tears into just about everything that comes across his bench. Including, most recently, a $1.3 million 110-GHz oscilloscope from Keysight. It’s a teardown that few of us will ever get the chance to do, and fewer still would be …read more
Have you ever seen the science experiment (or magic trick?) where you get water supercooled to where it isn’t frozen, but then it freezes when you touch it, pour it, or otherwise disturb it? Apparently, ice crystals form around impurities or disturbances in the liquid and then “spread.” A similar effect can occur in metals where the molten metal cools in such a way that it stays melted even below the temperature that would usually cause it to melt.
[Martin Thuo] at Iowa University used this property to make solder joints at room temperature using Field’s metal (a combination of …read more
