Modern submarines can dive up to 240 meters below the surface of the water. When the crew is ready to submerge, external ballast tanks that are normally filled with air, open to receive water. This makes the ship slightly negatively buoyant. #ImpossibleEn

Diving bear--Cartesian diver and submarine-like behavior /// Homemade Science with Bruce Yeany

896 views / 0 likes - added 7 years ago

The diving bear is a simple and fun experiment that is easy to build and use. It's behavior is similar to a cartesian diver and the sinking or floating of a submarine. It can help demonstrate concepts such as buoyancy (Archimede's principle), Pascal's pri

Designing a 7-segment hex decoder

625 views / 0 likes - added 7 years ago

Building a combinational logic circuit to decode 8 bits and display a 3-digit decimal number on 7-segment displays is complex. In this video, I build something much simpler—a circuit that decodes 4 bits to a one-digit hexadecimal display—and even that's p
