I want to know how do you build a homeade
seismograph?
Build simple electroscope - discharge time can show humidity and ionisation situation
Seismograph
Zhang Heng was the firts to invent the earthquake weathercock in 132 A.D.
it help tell the direction of where it came from and the slightest movement will make the ball fall if you are referring to the ancient china one
Detector rails generate redstone energy (for a redstone wire or other contraption) when a minecart is on them. You can make a simple minecart accelerator by placing rails like so: [minecart rail][detector rail][powered rail][powered rail][detector rail][minecart rail]
i just asked for a frequency detector jst as brain wave detector.
To make a simple gold detector, you can use a metal detector kit that includes essential components like a coil, circuit board, and battery. Assemble the coil, which creates an electromagnetic field, and connect it to the circuit board to process signals from metal objects. You can fine-tune the sensitivity and discrimination settings to better detect gold. For DIY enthusiasts, there are various online guides and schematics available to help build a more customized detector.
The earthquake detector, also known as a seismometer or seismograph, was developed in ancient China around 132 AD by the polymath Zhang Heng. His device, called the seismoscope, was designed to detect and indicate the direction of earthquakes. Modern earthquake detectors have evolved significantly and are now produced in various countries around the world, utilizing advanced technology for precise measurements.
there are two types:- 1) simple diode detector 2) practical diode detector the diode is common device used in am demodulator. signal(am demodulator signal ) is applied anode and output is taken from cathod
There is a device called a radar detector, but it will only detect a radar signal, not police in general.
Yes, and you wouldn't need the motion detector.
Your smoke detector may be beeping because the battery is low or the unit needs to be replaced. To make it stop, try replacing the battery first. If the beeping continues, consider replacing the entire smoke detector.
