Electrical apparatus start-stop circulatory timer circuit diagram

Published:2011/10/20 21:40:00 Author:Rebekka | Keyword: Electrical apparatus , start-stop circulatory timer

LM555 integrated circuit forms the basic duty cycle adjustable multivibrator. Discharge and charge circuit of C3 are connected to KH1, W1, KH2, W2 respectively in series for coarse tuning, fine-tuning the stop time. When the circuit starts to work, the power supply passes R3, HK1 series resistor and W1, V2 to C3, thenIC's pin 3 outputs high level. LED emitslight and the relay pulls in. Its contacts areconnected to the load. When the voltage on C3 rises to 2 / 3 supply voltage, IC flips, relay releases. Meanwhile, C3 passes V3, R4, HK2 and IC's 7 feet discharges power to the ground. When the voltage C3 drops to 1 / 3 supply voltage, IC flips and relay pulls in. So the cycle starts to work. Each block of HK1 and HK2 increase or decrease for 4.5 minutes. The adjustment range of W1, W2 is about 0 to 5 minutes.   (View)

Valuables pilfering tracker circuit diagram 1 (KD400/JD400)

Published:2011/10/19 22:28:00 Author:Rebekka | Keyword: valuables pilfering tracker

The circuit is shown as figure. It contains wireless Voice FM transmitter and wireless receiver, decoder.The transmitter is placed in the shellof precious appliances. It will automatically launch whistle sound frequency modulation (FM) radio signals. when the appliance is moved, the owner will get the signal by receiver. It will follow the stolen things untill the theft is caught. When someone is moving the valuables, KR and YA will be departed. The touch spot of reed switch will be cut. The TV1 gets bias current and be turned on. Pulse high jump is added to trigger control terminal TG of IC1to trigger itand make a sound. Figure B is receiver demodulation circuit.   (View)

Simple and practical mouse remote control circuit diagram

Published:2011/10/19 22:21:00 Author:Rebekka | Keyword: Simple and practical mouse remote

Generally, there are 4 circuit connection lines in the mouse and computer(the circuit device can accept up to four input data lines, and readers can select their own actual situation). They are the positive power supply, the data line 1, the data line 2. We will cut off the mouse connection to find out the four lines respectively. And we use the receiving end D6 and D7 of MC145026 encoded data transmission circuit data lines to receive the data sent by mouse lines 1 and 2. It will send the conversion data in the output of the chips D6 and D7, andyou do not need to change the mouse and computer of the circuit. And you don't need to install additional mouse drive software. All the features of the original mouse can also be used normally.   (View)
