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.....

These two circuits are interesting from an academic point of view. Their practical implementation...
This tester is for tracing wiring on Printed Circuit Boards. Resistors below 50 ohms act as a...
This circuit will synthesize two rear channels for quadraphonic sound when fed with a stereo...
At a predetermined level of declining terminal voltage, the circuit disconnects the battery from...
Using BA1404 can be designed a very simple and useful fm stereo modulator electronic project....
Following the same idea as the Chipstein and Cornell designs, the circuit uses an instrumentation...
The post explains a simple delay ON circuit which allows the connected load at the output to be...
By now many audio DIYers would be familiar with "What Compressor ", a project that apparently had...
The USB(Universal Serial Bus) specification provides the ability and energy. This change...
This circuit is designed in response to a request made by Mr Vignesh. What he requested was a...
The amplifier can be used in a number of projects to buffer and amplify outputs from devices such...
The beat frequency oscillator (bfo) is necessary when you want to receive cw signals. Cw signals...
This stereo FM wireless microphone also makes a great quality audio link. We tested it to beyond...
When the receiver is tuned to a M. W. radio station the resulting feedback howl, caused by the...
A constant current source of the differential amplifier circuit (2) having a constant current...
As shown circuit 555 is at the core of the flash circuit, when their normal work, the light...
As shown in FIG constituted by L4960 + 5 ~ + 40V switching power supply circuit. AC 220V voltage...
