foraging work, and then after the 30s delay fork into the wait state, it is suitable for outdoor use mousetrap. (1) Working principle of 23-11 knots electrical circuit diagram of the electronic mousetrap. VT1 ~ VT4 composed of a control circuit and related components, and its role is to enter the notification whether the mouse control system area, and alarm and control voltage generating electrical power to the road. IC, VT5 etc. alarm circuit, when a rat entered the control area, IC alarm signal by pushing VT5 speaker microphone BL sound. VT6 and the peripheral element pieces composed transmitter operating frequency 88 ~ 108MHz, launch distance of lkm above, in order to implement remote monitoring. VT7, T, etc. VD2 voltage generating circuit, the output of several hundred to several thousand volts pressure, to kill the mice enter controlled areas. When the manual switch SA is closed, the power supply to the control circuit power, then VTI-VT4 are closed, following the electrical alarm and t K is not energized high voltage circuit does not work. When the mouse enters that triggers when the equivalent of between A, B electrodes, a resistor. VT1 ~ VT4- are conduction, the relay K pull its contact K is closed, the alarm and high voltage generating power supply circuit is turned on. At the same time, the power supply to the cz charged by VT1, VT2, so that when the mice after departure triggers a relay delay about 30s closed. VT7 avoid prolonged work impaired, but also reduce the power consumption of useless. Alarm IC sent all the way through the speaker BL charcoal sound. Another way was prepared by a high-frequency oscillator consisting of VT6, and emitted outside. At the same time, the light emitting diode LED1, LED2 light. Since then the mice frightened and fled into the high-voltage triggers a t Arab was killed. Upon receipt of an alarm signal in the distance custodial staff with FM radio, to the scene in time to clear the dead rats.
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.....
