132 – Chinese Seismoscope

A seismoscope is a qualitative indicator of seismic activity — as opposed to seismographs which show quantitative data, typically through line graphs. The oldest known seismoscope is Chinese and dates backs from 132. It was a large bronze device that dropped a ball into a bronze container (one of the eight frogs on the image above) every time an earthquake was detected, thus producing a loud sound. The direction of […]

1660 – Galileo Thermometer

A Galileo thermometer consists of a set of floaters immersed in a clear liquid (typically ethanol) inside a sealed glass tube. Today a floater is typically a glass sphere containing a colored liquid and to which is attached a metallic temperature tag. The composition of a floater is irrelevant, its overall density just needs to be calibrated to a certain value and remain stable. Floaters being made of glass and metal, their volume – […]

1714 – Mercury Thermometer

The mercury thermometer was invented by Dutch physicist Daniel Gabriel Fahrenheit in 1714. It consists of a narrow glass tube with a bulb at the bottom, containing mercury. The volume of mercury changes with temperature; mercury is driven out of the bulb and up the tube as the temperature rises.

1961 – Voskhod Spacecraft “Globus” IMP navigation instrument

This device was the location indicator for Russian spacecrafts from the world's first manned spaceflight by Yuri Gagarin, 12 April 1961, until 2002. It contains a mechanical computer and a physical globe which rotated to always display the point on earth exactly underneath the spacecraft, or, alternatively, the point where the spacecraft would land if the re-entry rockets where fired at that exact moment. The […]

2014 – TiltWatch: Physical Tilt Indicator For Shipping Goods

This ShockWatch tilt indicator can be attached to packages which must remain upright during transportation. If the packet is tilted to either side, the little balls move into the next chamber. The recipient can then later check the degree of tilting the packet experienced during transportation. The upper row indicates tilting to the left, the lower to the right. The ball in the round indicator moves in […]

2016 – Turning Weight into Scale

This simple prop or analog interface by designer Chang Hee Lee is part of an art project titled "Three Studies of Synaesthesia", and studies how weight and scale could be associated with each other. The liquid between the two glass sheets immediately expands its surface according to the pressure it receives on the glass surface. The heavier the weight or pressure, the more the surface expands.
