Magnet Man Cool Experiments with Magnets
Experiments with magnets and electromagnets which can be built and demonstrated; for elementary school through high school classrooms. Can also be a starting point for science fair projects.Self steering gear
Self steering gear is equipment used on ships and boats to maintain a chosen course without constant human action. It is also known by several other terms, such as autopilot (borrowed from aircraft and considered incorrect by some) and autohelm (technically a Raymarine trademark, but often used generically). Several forms of self steering gear exist, divided into two categories: electronic and ...History of timekeeping devices
The oldest known sundial is from Egypt; it dates back to around 1500 BC (19th Dynasty), and was discovered in the Valley of the Kings in 2013. Sundials have their origin in shadow clocks, which were the first devices used for measuring the parts of a day. Ancient Egyptian obelisks, constructed about 3500 BC, are also among the earliest shadow clocks.Home of MiniMag Co.

Gravimeter: Gravimeter, sensitive device for measuring variations in the Earth’s gravitational field, useful in prospecting for oil and minerals. In one form, it consists of a weight suspended from a spring; variations in gravity cause variations in the extension of the spring.

According to , the gyroscope in the PS MOVE is a chip labeled Y5250H.We found this suspicious because the marking is reminiscent of a single axis yaw gyroscope from ST (presumably a custom variant of their LY5150ALH) whereas the PS Move is known to measure rotations on all three axes.Inventor | Britannica
Inventor: Inventor, a person who brings ideas or objects together in a novel way to create an invention, something that did not exist before. Inventors defy definition; as a result, they are frequently defined by what they are not. For example, though there is a close relation between invention and scienceDANYK.CZ Electrotechnic schematics, howto, DIY
