For this project I show how to make make a pendulum wave, an interesting science/physics experiment where a series of ...

The Foucault pendulum which was displayed for many years in the Smithsonian's National Museum of American History was removed in late 1998 to make room for the Star-Spangled Banner Preservation ...

PENDULUM SEISMOMETERS are among the oldest forms of instruments employed to record earthquake motion upon a stationary plate. In 1841 crude forms of such seismometers were used to record shocks at ...

Now, we know what you’re thinking — he must have used some kind of PLL to give an electromagnetic “kick” to the bob to trim the pendulum’s period. Good guess on the PLL, but the trimming ...

It’s an electromagnet pendulum analog circuit. Whether you’re building it, or just studying the schematics, this is a fun way to brush up on the non-digital side of the craft. The pendulum is ...
