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.....

The charger is based on a charging voltage of 2.4 V per cell, in accordance with most...
The combination of Ql, Q2 and Ul form a hysteresis oscillator to stabilize lamp illumination. In...
This generator will supply sine, triangular, and square waves from 2Hz to 20kHz. This complete...
The main part of this circuit Doorbell two timer NE555 ICs. When someone hit the switch S1...
A very simple frequency counter circuit is shown below and can be easily built by any electronic...
Here is a simple circuit which can be used for decoration purposes or as an indicator. Flashing...
This 5 volt regulated power supply circuit project is designed using the NCP3155 DC DC switching...
This circuit is an astable multivibrator, or oscillator. The two transistors are cross-coupled in...
Tiny, portable Guitar Amplifiers are useful for practice on the go and in bedroom/living room...
Lots of consumer electronic equipment like TV sets, VCRs, CD and DVD players employs infrared...
This chapter provides a variety of circuits of both line powered and inverter types for the basic...
It had been only a little over a decade since the transistor was invented when this article...
This circuit produces the power to drive a bipolar stepper motor. The rotation speed and the...
By the oscillator circuit, a counter, Iseki circuit of three parts. Oscillation circuit by the...
By the transistor VTi, VT3 and VTs and RC components constitute three separate multi-resonator...
