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 neat little circuit can play 8 note tunes at any speed you want. You select the notes with 8...
The Astable Multivibrator, which is generally used as a signal generator, is once again used here...
The test circuit gives an indication of the capacity remaining in a battery. By noting the time...
The regulator delivers 100-V at 100 mA and withstands shorts to ground. Even at 100 V output, the...
This is a design circuit for audio graphic equalizers, that are very common as commercial...
Below that is the clock section. The knob controls the internal oscillator`s speed, and that can...
This page describes a project a colleague and I completed between September, 2000 and March, 2001...
What is DAC Digital to analog converter (DAC) is used to get analog voltage corresponding to an...
This pdf file shows the schematic diagram of my home-built circuit to drive the PDR-56 probe. A...
An interesting circuit of a bicycle horn based on a popular, low cost telecom ringer chip is...
The single line diagram is circuit diagram where "one-line" is shown to represent three phases of...
This ion detector circuit detects static charges and free ions in the air. This ion detector...
The disk magnets are in attraction on each end of the power coil. The coil is pulse charged,...
Ic, spread the use of electric comparator LM339c1 / 4), the potentiometer B to set the desired...
As shown, this is a closed loop made up of three identical composition of the Schmitt trigger,...
