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 power supply section is the important one. It should deliver constant output regulated power...
Six LEDs are arranged to produce a display the same as the dots on a dice. When PBI is depressed,...
Output frequency or tone of this oscillator circuit varies with the temperature at which the...
This constant current constant voltage SMPS can be used to efficiently charge a battery. This...
The square wave is generated by a 7555 timer operating with a supply of 10V and thus generating...
Here is the circuit diagram of a simple stepper motor controller using only elementary parts. The...
This is my first successful vacuum tube project. The output of this small amplifier in which a...
Foggers used to generate fog and smoke effects operate by heating a special fogger fluid. They...
This circuit uses a couple of Op-amps to produce an interesting sound effect. The left hand CA741...
The first time you sign into developerWorks, a profile is created for you. Select information in...
A 2003 Monte CarloSS, I am having trouble with low idling, it cuts off while driving or when in...
A simple radio receiver circuit is shown in Fig. 1. This receiver is designed for reception of...
As shown, the circuit consists of a dual-core 556 and the light emitting tube. The left half of...
Circle MIC to lift the damper after it is converted into a voltage signal sounds, the op amp A...
