The circuit described here uses ultrasonic oscillations and operates based on the propagation velocity of these oscillations in the air. Thus, we can easily determine the distance of two points if the time within which the wave travels this distance is.... -
Sometimes the precious metals are hidden too deep and are not detected except with complicated devices. In many cases, however, small pieces of precious metal buried near the surface can be detected by relatively simple means. Everyone is very attractive to.... -
Many times for various reasons we forget or can not water the plants that we have in our homes. And many humidity sensors units just notify us with a beeping sound or with a flashing light, that the pot needs watering. But what if we are away from home? This.... -
The principle behind a metal detector is really very simple. Proof of this is the circuit that follows, in which it proves that the construction of a metal detector can be done in the minute, with few components that we find very easily everywhere. With the.... -
The sub-harmonic bass generator is a sound producing unit for guitars. The sound it produces looks very much like that of the bass guitar. The octave generator is sometimes quite unusual since it does not produce any of the usual ways of coloring the sound,.... -
In the past the sounding (sea bottom measurement) was done with the "bullet", that is, with a heavy lead object that the seamen plucked into the sea hung from a calibrated rope. As soon as the "bullet" reached the bottom, the depth appeared directly from the.... -
This Amplifier was designed to have the following specifications: Distortion less than 0.1% at full power of 100W even at 20KHz. Power has to be attributed to an extended bandwidth. The output transistors must be protected against short circuits. The power.... -
A series of LEDs serve to alert the gardener when plants need water. Using two conventional digital integrated LEDs and a series of LEDs, we make a very useful device for gardening. The device detects the amount of water in the pot and alerts the grower..... -
The best human ear can capture sounds from 20Hz to 20KHz. These limits are known to be the broadest that can exist. Normally the normal limits range from 100Hz to about 13KHz and depend on the age and health of the individual. We for our measurements and to....

The timing components are Rl, R2, and C,. Cl is a bypass capacitor used to reduce the effects of...
A BA1404 IC is used to generate a complete FM MPX signal. The chip contains all of the necessary...
Added a BASIC preprocessor made in python that allows you to write code withought line numbers...
Welcome to the weblog where we discuss about electronic circuits schematics, PCB design, diy kits...
ZSSC1856 of ZMDI Company is the double-channel ADC of integrating embedded MCU, made up of two...
The build makes use of a 10 x 20 grid of RGB LEDs controlled by the myRIO. It`s played by using a...
This circuit uses a conventional spring loaded mouse trap, available from hardware stores....
Experimenting with the window motor. The reason the window motor is so powerful, is the minor...
Here is a high performance RF amplifier for the entire VHF broadcast and PMR band (100-175 MHz)...
