Let’s say you want to blink an LED. You might grab an Arduino and run the Blink sketch, or you might lace up a few components to a 555. But you needn’t go so fancy! [The Design Graveyard] explains how ...

[Eric Wasatonic] had a box of SWB2433 transistors that he had very little information about. In order to discover their properties, he fired up his curve tracer to compare these transistors with more ...

A single-electron transistor with a central component -- an island only 1.5 nanometers in diameter -- that operates with the addition of only one or two electrons has been developed. The transistor, ...

Recently, I wanted to build a Sleepy-LED Eye as an add-on indicator for a small personal project. My idea is a near-replica of the iconic breathing pattern used for the “sleep” indicator in Apple ...
