drain off the battery and may give unreliable operation. To deviate this short coming, you may use the circuit given in the below. Which enables power to be drained from the battery only when timing action is ON. For the idling period, the power consumption is zero. The circuit uses a double pole relay. One pole is used to energize the load, the other pole is used to cut off the supply line when the timing action is over. A push on the Start` switch energizes the relay RL1. A pair of contacts of the relay provides the supply voltage to the timer which get triggered. Oscillations start and when the output at pin 3 becomes HIGH, the diode D1 permits current to flow through the relay, thus latching it up. The frequency of the oscillations depends on the time constant given by T=1. 1G—C1G—(R1 R3). After this time is over, the output at pin 3 goes LOW; the relay is released, and the load is de-energized. We aim to transmit more information by carrying articles.

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.....
