Does does it forget to be erased the small lamp and the headlight of the car, the battery go up, and is there what to the engine has not started once and twice everyone I am using it for a long time since then thinking about the circuit that prevents this in around 1980. It is possible to do with an easy circuit and try by all means, please. Even

if it fails and the car is broken, I am not concerned at all. It is a circuit that the part where the schematic diagram is yellow adds. The series circuit of the diode and 12V buzzer is only added between the place and the door switch 12V`s being impressed when the small lamp is lit. The purpose of the silicon diode is to prevent the backward voltage from hanging to the buzzer. The current is prevented from in a word AUTO room lamp SW, closed the door, and flowing to the small lamp circuit through the buzzer when the small lamp is turned off. The diode and the joining terminal are installed in the buzzer as shown in the photograph. The purpose is to remove at once when trading a used car in for a new one. Though the person who can remove soon may connect directly. The insulating tape is rolled in the soldering part after this. If do the prick of the needle to the electric wire and small lamp SW is operated while measuring the voltage between bodies with the tester, it is easily searchable. Please wrap the tape around the eye of a needle part if you are anxious.
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.....
