[Brad] just acquired a 32×32 RGB LED matrix and he jumped right into the deep end with his first project. To try out his skills on the device he used an Arduino to drive a slew of pixels with bouncing ...

The physics of a bouncing ball is well understood, but a liquid-filled ball can still surprise scientists. A new study published in the American Institute of Physics' (AIP) journal Physics of Fluids ...

[Eric Archer] constructed an analog computer to model the physics of a bouncing ball. The core is a TL074 opamp that does all the integral math. He had no trouble finding descriptions of analog ...

A physics demonstration shows how bouncing balls can appear to keep moving endlessly, explaining the energy transfer and ...
