bouncr | Resonant Baby Auto Rocker DIY Project

bouncr is a C++ library typically used in Internet of Things (IoT), Nodejs, Raspberry Pi, Arduino applications. bouncr has no bugs, it has no vulnerabilities and it has low support. You can download it from GitHub.

i was bouncing my bub in her baby bouncer and thought "there has to be a better way to keep bub bouncing than to sit here and manually do it." at first i thought about some mechanical linkage to bounce the chair, but then later in the shower the idea came to me. a wire hoop baby bouncer is an underdamped simple harmonic oscillator. simple harmonic oscillators have a resonant frequency. as the force driving the system to oscillation approaches the resonant frequency, the energy transfer becomes very efficient, and a small input results in a large bounce. [wikipedia] [wolfram math world] as the frequency of the stimulus goes higher or lower than the resonant frequency, the applied force actually starts to dampen the oscillations, rather than increase them. if i could measure the resonant frequency of the chair + bub aggregate, then i could drive an oscillator at that frequency and that should make the chair bounce. to measure the resonant frequency i would need an accelerometer. and then i could drive oscillations
