Levitating Cube

For the first time in the Modding & Tweaking series we present a project that is not based around a microcontroller. Instead, we look at an experiment that has enchanted audiences for decades, updated with a laser diode and minimal control electronics. Before we start: this project sits firmly in the category of ‘classical experiments’. Anyone with a scientific background will surely have seen, performed, or at least thought about a similar trick before.
