Wave power does not seem to be a super fast-moving sector. We've seen plenty of fascinating ideas in this space, from jetty-mounted pump arms, to telescoping barrels, to elastic sea-bed flappers, and ...

Sawtooth- or exponential-ramp relaxation oscillators are common and generally easy to build. However sometimes a cleaner waveform is desired, and generators of even-symmetric waveforms are a bit more ...
