There is no battery charge indicator, so I don’t know how much is left after all my experimenting, but I didn’t recharge it once. A software update correcting some of the strange English would be nice ...

Let’s consider an example with an NPN transistor, as shown in Figure 3. This is a common emitter transistor amplifier that appropriately biases an NPN transistor (2N2222) to fix its operating point.

Researchers at the University of California- Santa Barbara have devised a new framework that could contribute to this quest, enabling the fabrication of scalable three-dimensional (3D) field-effect ...

The chances are that many of you will have made an FM “bug” style transmitter, a simple one-transistor oscillator usually driven by a small electret microphone. It’s also relatively ...
