Collaborate Disseminate
Back in 1996, Bob Pease posed an experiment in an April Fools column. “Take an ordinary NPN transistor, ground the base, pull the emitter up to 12 V with a …read more Continue reading An Explanation of a Classic Semiconductor Riddle
We’ll be honest, we were more excited by Duke University’s announcement that they’d used carbon-based inks to 3D print a transistor than we were by their assertion that it was …read more Continue reading 3D Printed Transistor Goes Green
In a shining example of the inexorable march of technology, IBM has unveiled new semiconductor chips with the smallest transistors ever made. The new 2-nanometer (nm) tech allows the company to cram a staggering 50 billion transistors onto a chip the size of a fingernail.

A huge portion of electronic devices that are discarded at the end of their lives are never recycled, and a big part of the problem is the difficulty in separating out and recovering the valuable materials that make them up. With a view to solving this… Continue reading World-first printable transistor is fully recyclable with water and sound
We like to pretend that our circuit elements are perfect because, honestly, it makes life easier and it often doesn’t matter much in practice. For a normal design, the fact …read more Continue reading The Imperfect Bipolar Transistor
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
When working around mains voltages, it can be useful to know whether a given circuit is live or not. While this can be done by direct connection with a multimeter, non-contact methods are available too. A great example is this simple wireless AC current detector from [NEW PEW].
The circuit …read more

In the fantasy world of schematic diagrams, wires have no resistance and square waves have infinitely sharp rise times. The real world, of course, is much crueler. There are many things you can use to help tame the wild analog world into the digital realm. Switches need debouncing, signals need …read more
We’ve probably all given a lot of thought to breathing this year in various contexts. Though breathing is something we all must do, this simple act has become quite the troublemaker in 2020. They say the best art imitates life, and [bornach]’s Astable Exhalation certainly does that, right down to …read more

The ideal component tester is like a tricorder for electronics — it can measure whatever it is that you need it to, all the time. Maybe you have a few devices like an ohmmeter and maybe a transistor socket on our multimeter. But what do you do when you need …read more
