This tester is primarily meant to test bipolar transistors. It can indicate the type of the transistor as well as identify its base, collector and emitter pins. The circuit is very simple. The ...

One of the lost pleasures of our modern world is the experience of going shopping at a grocery store, a mall, or a drugstore, ...

Hacker [Dino Segovis] is back with yet another installment of his Hack a Week series, and it’s looking like he isn’t too worse for wear after hunkering down to face hurricane Irene. This week, it ...

Most students run away from science and technology classes because they find it difficult to use some of the complex devices during practicals. To help this set of students, three students of St ...

Researchers at the MIT's Microsystems Technology Laboratories (MTL) have developed a germanium p-type transistor whose carrier mobility doubles that of previous experimental p-type transistors and ...

This tester is intended to quickly check whether a transistor is functional or not and possibly also select two or more transistors with (approximately) equal gains. This is about the simplest ...
