IMMOBILIZER

Published:2009/7/2 4:46:00 Author:May

A flip of 51 puts the circuit into action. Power for the circuit is picked up from the ignition switch, and the circuit receives no power until the ignition switch is closed. When power is turned on, capacitor C1 is not charged and the emitter-follower Darlington pair (formed by Q1 and Q2) are cutoff, thus no power is applied to the relay (K1), which serves as Q1's emitter load. The relay's normally-open contacts are connected across the vehicle's points. (At this time, the relay contacts are open and have no effect on the ignition system). C1 charges by way of R1, causing the voltage at the base of Q1 to rise steadily. Thit creates a similar rise in the voltage at the emitter of Q2. A Darlington pair is used to provide a high input-impedance, buffer stage so that the voltage across C2 is free to rise almost to the full supply potential. Loading effects do not limit the charge potential to just a few volts. Eventually, the voltage applied to the relay becomes sufficient to activate it. The contacts close and short out the points. The ignition system now doesn't act properly and the vehicle is disabled. If the ignition is switched off, power is removed from the circuit and diode D1, which was previously reverse-biased, is now forward biased by the charge on C1. D1 allows C1 to rapidly discharge through R2 (and any other dc paths across the supply lines). The circuit is ready to operate when the ignition is again turned on. The engine will operate, but not for very long. The values of R1 and C1 provides a delay of about 25 to 30 seconds. Increase R1's value to provide a longer delay;   (View)

INTERMITTENT_WINDSHIELD_WIPER_WITH_DYNAMIC_BRAKING

Published:2009/7/2 4:45:00 Author:May

The circuit provides a delayed windshield wiping, and dynamic braking of wiper blades when they reach the rest position. This prevents the blades from overshooting, which might cause them to stop at a point where they interfere with the drivers' vision.With the original wiper switch off, switch S1A turns on the delay circuit and S1B disconnects the original automotive wiring. When S1 is tumed off, the original wiring controls the system and the delay circuit is bypassed.Turning S1 on applies the + 12-V battery to U1 which is a voltage doubler that produces + 18 V. This higher voltage supply is necessary to ensure reliable turn on of Q1 by multivibrator U2. This arrangement provides about +18 V to the gate of Q1, whose source is +12 V minus the VDS drop of Q1.Q1 remains on for a time determined by the WIPES potentiometer. The interval between wipes is controlled by the PAUSE control. When C1 drops below +4 V, U2 ftres, tuming Q1 on and restarting the cycle.   (View)

8038 function generator circuit

Published:2011/7/19 22:19:00 Author:John | Keyword: function generator

The figure shows the 8038 function generator circuit. Function generator formed by integrated circuit chip 8038 can obtain square wave, triangle wave and sine wave at the same time. Triangle wave can be generated directly by the capacitor discharge current. And square wave can be obtained by control signal. The sine wave is obtained by the broken line approximation circuit from the triangle wave. The sine curve obtained in this way is not a smooth line, whose distortion was about 1 percent. The needs for general purpose can be met. PR1 in the potentiometer circuit is used to adjust the frequency to be ranged from 20 Hz to 20 kHz. PR2 is used to adjust the waveform’s distortion and PR3 is used to adjust the waveform's duty cycle.   (View)
