[michimartini] over on Hackaday.io loves playing with multivibrator circuits, and has come across a simple example of a ring oscillator ... short applying to one transistor element in order ...

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 ...

The design idea presented here derives from one of his circuits published on page ... Figure 3 Thermometer oscillator waveforms. Although as noted in the Willams application, the Q1 sensor transistor ...

This FM transmitter circuit uses four radio frequency stages: a VHF oscillator built around transistor BF494 (T1), a preamplifier built around transistor BF200 (T2), a driver built around transistor ...
