I enjoy breadboarding the 555 oscillator circuit for its simplicity and versatility. It's a great way to explore timing and waveform generation. For something more advanced, Chua's circuit offers intriguing chaos theory applications. This website also provide good information related to it. https://350ppm.co.uk/
Are you sure? yes | no
555 but just because its easily adjustable with a pot
Lately I have been leaning towards hard coding attiny13a MCUs to generate a particular frequency instead because I need faster freqs.

Many years ago, I was toying with the Takagi function (a sort of fractal) as a software based synth. It's a summation of triangles, so it could be approximated by some 555s and an op-amp.
On the board now is a three-phase VCO that uses LEDs in place of varactors.
