How to make a single transistor oscillator In this video we crate a single transistor oscillator by taking advantage of the reverse breakdown region of a 2n2222 transistor. You will need at least 12VDC and may have to try a few transistors before you find one that will oscillate. Take note of the waveform, you get very fast rise times and and nice slow capacative decay.
