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.....

At VHF, both the 1/4-wavelength monopole and the 5/8-wavelength monopole antennas are widely...
This circuit is a circuit diagram of ECM Mic Preamplifier. A microphone amplifier that can be...
Here`s a design circuit that has function that it will help to filter out the interference signal...
It is illegal in most countries to operate radio transmitters without a license so take care with...
Here we demonstrate the use of an Arduino PWM output pin to generate sound. The output pin can be...
This circuit is intended to signal, through a flashing LED, the exceeding of a fixed threshold in...
The RF oscillator using the inverter N2 and 10. 7Mhz ceramic filter is driving the parallel...
A very simple FM CB radio receiver can be designed using this electronic diagram below. This FM...
Inverter or ondulator, is an electronic circuit used to turn direct current (DC) into alternating...
This circuit is the basis for the dimmers in a model theatre lighting system which uses touch...
Here is the circuit for the FM Bug. In total there are 18 core components that are needed for the...
The full schematic for this project is really, really big so if you want to see it, go ahead and...
A phase-shift audio oscillator with excellent distortion characteristics thanks to "softened"...
Using this simple circuit, you can make an 18 LED flasher to decorate the X`Mas Tree. The White,...
As shown in FIG by DN-41 consisting of high-current switching regulator. DN-41 features...
