A Planet Analog article, “2N3904: Why use a 60-year-old transistor?” by Bill Schweber, inspired some interest in this old transistor and how it’s commonly used, and if any uncommon uses might exist.

The circuit was created to produce an oscillator operating at low frequency for use in the production of electronic music and experimenting and testing tone controls. Oscillator – an electronic ...

(Nanowerk News) Physicists of the Technische Universität Dresden introduce the first implementation of a complementary vertical organic transistor technology, which is able to operate at low voltage, ...

Chaotic circuits can arise from either computed (using Analog Computers or Digital Computers) solutions to coupled differential equations or from unstable systems/circuits. A new open-source circuit ...
