The CCD camera sensor is device that have very useful. This project has small size. But quality is a lot good. We can install with Television easily through the video in terminals. and connects to the video signal modulated to To send a broadcast RF signal is explicit is better. This project can be adapted to many applications such as installed in

the bedroom children. To noticed the baby through the TV monitor. or When guest press a doorbell the front yard, we will know is who. or Application of an intercom to contact the visible image once. Installed in shops, factories and other places to secure it better. This small CCD camera video are model of ready-made digital camera has the connecting to use of 3 wire. Able to work in the dark or under illumination 0. 1 lux. Using an infrared beam. As described above the CCD model can be easily apply just correctly connects the power supply. We will be obtained the video signal level 10 volts peak to peak at impedance of the signal wire 75 ohms then connect to TV that has Video in immediately. But we must build the power supply circuit add the 1 set. By the characteristics of the circuit as follow in Figure 2. The working of power supply section will have the transformer T1 converts from AC220V to AC12V only, then into the D1-D4 diodes that is connected as the bridge rectifier into DCV out to C1-capacitor, which acts as a smoothing filter current is DCV again We need to create a section of the power supply circuit. As the PCB layout and the positioning equipment in Figure 3 Which can build by yourself easily. or If you do not want to use the PCB can be soldered directly to the equipment in Figure 4. We able to optimize this project with the Simple video transmitter circuit In the wireless to can be used with televisions...
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.....
