World-first printable transistor is fully recyclable with water and sound

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

Simple AC Current Detector Built On A 9 Volt

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

Circuit VR: Squaring with Schmitt Triggers

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

Circuit Sculpture Breathes Life into Discrete Components

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

Check Your Pockets for Components

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

Controlling a Broken Super Nintendo With MIDI

A Super Nintendo that has trouble showing sprites doesn’t make for a very good game system. As it turns out, Super Mario World is a lot less fun when the titular hero is invisible. So it’s no surprise that [jwotto] ended up tossing this partially functional SNES into the parts …read more

Chaotic Oscillator From Antique Logic

While working on recreating an “ancient” (read: 60-year-old) logic circuit type known as resistor-transistor logic, [Tim] stumbled across a circuit with an unexpected oscillation. The oscillation appeared to be random and had a wide range of frequency values. Not one to miss out on a serendipitous moment, he realized that …read more
