This is a little circuit that i designed that could be used for achargingcontroller or voltage limiter. Its very useful if you are thinking of maki. In the assembly of the circuit u can alter the circuit as you please. For instance ididn`tgo as exact as theschematic. Just follow the diagram belo. In the circuit that i build thatsnottotally the same

as the in the diagram, is suppose to turn on the led at 8V because i used a 5v and 3v zener. I. If turn the comparatorpositiveand negative leads around will have the reverseeffect. Imeaninstead of turning on at 8V it will turn off and any. This is a little circuit that i designed that could be used for achargingcontroller or voltage limiter. Its very useful if you are thinking of making a solarcharger. In the circuit that i build thatsnottotally the same as the in the diagram, is suppose to turn on the led at 8V because i used a 5v and 3v zener. I also used a two 9 Vbatteries which voltages differ. The circuit i suppose to turn the led on at 8 V and any voltage lower than it should go off. If turn the comparatorpositiveand negative leads around will have the reverseeffect. Imeaninstead of turning on at 8V it will turn off and any voltage thats lower than that it will be on. Sorry idon`thave a picture of that particular instance, but i will put in one any way. [ for decorative purposes] I did not understand which component you used and why the 5V supply Can`t we use a comparator that derives the required power from the charge capacitor Will you please explain so that it`ll be easy for me to make this circuit. Please help. Thank u for the reply. The problem is that the solar panel I am using only give 1. 5 V output. So I think may be I need to use some sort of amplifier because I can not use any external power supply. And...
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.....
