This circuit is the electronic emulation of the I Ching, a form of divination originating in With this dataselector, only one RS port is used to connect two RS devices i. When my girlfriend and I moved into our small apartment in San Francisco we wanted to setup some This section serves to strengthen the signal until the signal level is required. IF amplifier is This is a circuit for generating a sine wave from a single operational amplifier.

The feedback Using ceramic tuning 3. The goal of this project was to make an interactive baseball game inspired by pinball. There is a The diacs, because of their symmetrical bidirectional switching characteristics, are widely used This electronic door buzzer circuit schematic has a very simple function and is very easy to This circuit could be used depending on your circumstances by a gentleman to summon his butler, Light onphototransistorQ1 Radio Shack produces voltage change across R2 for Circuit shown in Figure The circuit is very simple, cold PTC thermistor element, jump Posted on Feb 5, Under: Repository-circuits.

If you could not found one in your local store, buy PIR motion sensor online. The 12V DC req. When you power-on the circuit after assembling all the components including the CFL, the CFL will glow for 10 seconds, turn off for 30 seconds, glow for 10 seconds and then turn off. Now the circuit is ready to work. Any movement across the sensor module is detected, about 3.

Now the triac BT fires to provide full V and light up the tube. If the switch S1 is not in the hold position the CFL will be on about 10 seconds as programmed in the sensor module.

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 Simple Metal detector circuit with CD 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 Fully automatic watering circuit for flower pots.

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? Simple deep searching metal detector circuit. 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, Echo Depth Sounding Sonar for Boats. 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.

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. The device detects the amount of water in the pot and alerts the grower The best human ear can capture sounds from 20Hz to 20KHz. These limits are known to be the broadest that can exist. Normally the normal limits range from Hz to about 13KHz and depend on the age and health of the individual.

PIR Bs1600 / HC-SR501

Here is a motion sensor system based on PIR motion detector module BS or BS that can be used for security or corridor lighting in power-saving mode. The 12V DC power supply required for the motion detector and the relay driver is derived from V, 50Hz mains using a transformerless circuit as shown below. The working of the circuit is simple. When you power-on the circuit after assembling all the components including the CFL, the CFL will glow for 10 seconds, turn off for 30 seconds, glow for 10 seconds and then turn off.

The need for residential and office security, especially at night is the intended use of motion sensor lights. Human motion detector is widely available in the market with prices varying depending on the features and capabilities inherent job. This type of motion sensor lights can be classified according to place of installation, the outdoor and indoor motion sensor lights. However, if the motion sensor mounting is quite far and did not require a long wiring, you can choose the type of wireless motion sensor lights. However, if you are accompanied by practical electronics skills, you can build yourself such motion sensor lights. By connecting the output of the sensor module into a high-gain amplifier which is equipped with a relay on the circuit schematic as below. The 12V DC module BS or BS power supply required for the motion detector, and the relay driver is derived from V, 50Hz mains using a transformerless circuit.
