Electronic rodent control circuit

Posted on Mar 28, 2007

It is said that the mice are more sensitive to electromagnetic fields, which is why the high-voltage grid rodent generally poor results. Electronic rodent control described here, no high-voltage power line usually, it does not cause mouse alert,

but as long as the body of a mouse trigger power grid, high-voltage power grid will immediately be able to instantly kill him, the rodent is better. working principle Circuit shown in Figure, B is an isolated step-up transformer. Due to the use of land as a grid electrode to prevent Warfarin mains security devices malfunction, the transformer circuit and mains isolation. Secondary low pressure by about 6V VD1 rectifier, C1 filtering DC voltage of about 7V obtained for control. High voltage alternating current by a pulsating rectified voltage VD2 obtained power for tag. Way thyristor SCR for a high on / off control, SCR cathode connected to the power line by LAMP. Static, due to the base circuit of the transistor V1 suspension and off, SCR is also turned off the power grid to be only between a low DC voltage, thereby generating an electric field is weak, so that the mouse will not raise the alarm. When a rat across the grid, V1 immediately turned the SCR triggered by high pressure pulsation LAMP immediately applied power line, the mice were killed. At the same time, V2 is saturated conduction, the relay J pull power, electric bell DL power and started to inform staff will promptly remove dead rats. Component selection and production Component list is as follows Number Name Type Quantity R1 resistor 100K 1 R2 * 200 resistor to be adjusted 1 R3 resistance 5.1K 1 C1 electrolytic capacitors 220u 1 C2 electrolytic capacitors 47u 1 VD1,3,4,6 IN4007 4 VD2 rectifier diode rectifier diode IN5408 1 VD5 switching diode IN4148 1 V1 transistor 9012 1 V2 transistor 9013 1 SCR way SCR BT169 1 J relay 6V small 1 BX fuse 0.5A µ0.5cm 2cm 1 B transformer restructuring, 1 LAMP incandescent 60W / 220V 1 B selection control transformer 300W about restructuring, the low voltage winding removal, another with µ0.25mm enameled wire around 1200 turns, tapped at 13 turns for the low-voltage winding. J 6V with a small relay. The production of all components mounted on a circuit board. Available wire grid on the ground 2cm high number of porcelain insulation supporting wound channel is formed with a common circuit nails driven into the ground. To enhance the effect, you can splash some water on the ground.

Zero consumption Anti-theft High power Code Switch for E-Bike Batteries

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....
Ultrasonic distance finder circuit

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 CD4030

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? This....
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....
Sub-Harmonic Bass Converter for Electric Guitars

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....
100W HiFi Audio Amplifier Circuit

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....
Plant-Pot Water Level Indicator Circuit

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.....
