This project fits more for custom made battery casing that can have more space to hide things inside. This switch with few alterations can be used for any other project as well but is designed based on e-bike needs! This project use a clever functionality of.... -
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.....

This circuit is useful where fast signal acquisition and high precision are required, as in...
After buying an arduino and some 8x8 LED matrices I really needed a project to make good use of...
The series is a series of input buffer equal to the output. In this is such a common collector...
A series of LEDs I would like to have display at 2 brightness levels and am confused how to...
The pressure sensor (MPX4100)MPX4100 is a pressure sensor that is equipped withsignal...
I would have assumed that anyone interested in building one of these would have a reasonable...
In the design of microcontroller based electronics project, the use of Reset IC is critical for...
The 30 watt amplifier schematic shown below provides an appropriate power boost with an input of...
This article explains the construction and working of feedback oscillators with detailed...
Measured output power and efficiency of a 6 dBm 130nm CMOS class-D inverter chain, using gate...
There are only 4 parts to the circuit, including the indicator LED. There is a hand-wound coil, a...
The use of electrically excited gas discharges significantly predates the invention of the...
This power supply based 7805 IC regulator, it can provides a regulated output voltage of between...
This page will be updated as Material becomes available. This New System will essentially replace...
The magnetometer was moved to an outdoor location and a specialized enclosure was built. An...
Cook in advance to open the door with a coal stove, before using the fire to be strong....
Circuit as shown, it is by the sound transducer sensing switch/electrical, light control switch,...
