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 circuit modulates a light beam with voice or music from the output of an amplifier. If the...
This circuit is for the purpose of monitoring automotive lighting. Two special ICs are available...
Using a CMOS IC TT8486A TT6061A you can build a very simple dimmer circuit which can be used to...
use microcontrollers to communicate in serial between the microcontroller (AVR-006 kit) with a...
This amplifier can be used for practically any application that requires high power, low noise,...
The State Jal Boards supply water for limited duration in a day. Time of water supply is decided...
The basic circuit described in this document is capable of generating up to 30 kilovolts or more...
This broadband AM receiver enables you to monitor` the shortwave radio band. The circuit has been...
This machine was near-and-dear to me as it was my first real computer, an Ohio Scientific...
CD4069 is a digital integrated circuit fabrication using boron to delay light touch, it also...
