No idea but they are incredibly easy to make. You need a very heavy weight with a marker attached. This is suspended, but touching, a paper trace that is usually moving, but not necessarily. They work on the principle that the weight and pen will stay still if the earth moves. (A stationary object will tend to remain at rest unless acted upon by an outside force) The earth moves the pen doesn't so a mark appears on the paper. The sensitivity depends on the weight used and the stability of the platform it's mounted on.

A Richter Scale is not the same thing as a seismograph. The Richter Scale expresses the magnitude of an seismic event. it uses an open-ended logarithmic scale for expressing the magnitude of a seismic disturbance (as an earthquake) in terms of the energy dissipated in it with 1.5 indicating the smallest earthquake that can be felt, 4.5 an earthquake causing slight damage, and 8.5 a very devastating earthquake.
A seismograph is a very simple instrument to construct -- the more precision the recording the more it will cost. To make accurate determinations, three are generally used to record waves in various directions.
