In this session of Logic Noise, we’ll be playing around with the voltage-controlled oscillator from a 4046 phase-locked loop chip, and using it to make “musical” pitches. It’s a lot of ...

(c) Maximum flexible oscillator frequency. (d) Estimated output measurements based on simulation. (e) A dynamic chart for visualization of the output parameters in function of the input frequency. (f) ...

One of those was the mechanical oscillator, and [Integza] had a go at replicating the device himself. (Video, embedded below the break.) Initial attempts to reproduce the technology using 3D ...
