On my video channel you can see my other pre-made homemade seismometers-DIY simle and cheap piezo seismometer-10 sensitive seismometer. Tie a piece of string slightly longer than the length of the box to each hole.
This is a diagram of a homemade seismograph.
Homemade seismograph. Tie a piece of string slightly longer than the length of the box to each hole. Poke two holes in the top of the box making sure they are the same distance apart as the holes in the cup. Push the two pieces of string through the holes and tie them together on.
A typical seismograph has a pen attached to a heavy weight. The weight is free to swing back and forth or to bounce up and down on a spring. The pen touches a rotating cylinder of paper so that the pen draws a line as the cylinder rotates.
If the ground does not move the pen draws a smooth straight line. The homemade seismograph will detect the movement of the ground thanks to a magnet that hangs from a spring so that it can bounce up and down freely. A stationary coil of wire is placed around the magnet on the reference surface.
You can make a simple seismograph to demonstrate how this machine works. Fill a 2-liter soda bottle with water and use wire to suspend it about 1 above the surface of a table using a sturdy stick or ruler set across stacks of heavy books. The bottle should hang freely between the books.
Piezoelemente kommen zum Beispiel in kleinen Lautsprechern zum Einsatz. Legt man eine Spannung an so verändern sie ihre geometrische Form sog. Handelt es sich um eine periodische Spannung so schwingt auch der Piezo periodisch mit dieser Frequenz und kann dadurch Schallwellen erzeugen.
And finally this is a completely new sensor design invented and patented by me that is both very sensitive and simple to buildI projected it on the basis of previous experience in making such devices.

Multiplying Lever And Recording Pen. To the steady mass is connected the short arm of the multiplying lever I. The short arm consists of a bit of brass wire.
12 three inches long. It is inserted into the cork f which serves to. A seismograph is an instrument that detects and records ground motion.
Ground motion can be caused by something man-made such as a mine blast or a nuclear explosion. Or by natural events such as landslides volcanic activity or most often earthquakes. This is a diagram of a homemade seismograph.
Our homemade seismograph detected earthquakes up to 100-200 km away w9 depending on magnitude. With our commercial seismograph w10 we detected earthquakes of 40 on the Richter scale from 500 km away. Options 1 and 4 have the advantage.
By Marc de Vinck. With this DIY project you can record earthquakes from around the world. This is a well-documented build but you will have to purchase some software to interface with your seismometer.
This site is a good place to start your amateur seismology and research. Scientists use special machines called seismographs to record the seismic waves or movements in the earths crust. Each magnitude number on the Richter scale represents the maximum amplitude of a seismic wave at a distance of about 160 kilometres.
You can make a simple seismograph in the following science experiment. Homemade seismometer How to make your own seismometer at home. A seismometer also known as a seismograph detects amplifies and records earthquakes as well as other ground motion.
Heres how you can make your own using materials commonly found in. A seismograph is an instrument used by scientists to measure the motions of the Earths surface. A seismograph is a simple pendulumWhen the.
