Category: Inside Circuits Views: 3366 Rank: 0 Capacitor Cl is connected continuously through the supply of 3 volts to 10 megohm resistor Rl. The capacitor is charged (relatively slowly) to 3 volts. The wink SWI is closed, it connects the charged capacitor (Cl) in series with C2 and R2. The capacitor C2 begins to charge, by placing a positive voltage during the gate of the SCR and turn it on. The two parallel `self-flashing` bulbs I1 and 12 on Tum.  They flash on and off the SCR and the circuit is turned off until the vehicle is driven off the switch and C1 can recharge.
Related circuits The LT1012 corrects de errors in the booster stage, and does not set high-frequency signals. Fast signals are fed directly to the stage via Q5 and the 0.01-uF coupling capacitors. De and low-frequency signals drive the stage via the op-amp"s output. The output stage consists of current sources,... Full-Cup Detector For The Blind At the heart of the Full-Cup Detector is a 555-oscillator/timer configured to produce a 15-Hz click, until Remote Control Extender Circuit A signal from an IR remote control is converted from IR radiation to a frequency pulse that can be transmitted tlirough coaxial TV cable or any other two-conductor wire to another room, Astable Multivibrator Or Free-Running Square-Wave Oscillator Circuit This free-running square-wave oscillator uses two npn transistors. Output frequency is approximately 300 Hz Time Delay Flash Trigger Circuit Circuit The circuit is built around a single 4093 quad 2-input NAND Schmitt trigger. IC1a, IC1b, and IC1c of the quad two-input NAND gate 4011 are connected as an astable multivibrator; IC1d is connected as an inverter. Terminals 3 and 11 of the 4011 produce square waves with opposite phases. The square waves, eP, at the output of IC1a, passing through differentiator C4R13,... This circuit monitors the voltage of a battery and warns the operator when the battery voltage is below a preset level by tumingon an LED. The values are set for a 12V automobile battery By vocalizing the numbers and symbols of its~eypad, the phone provides an audible confirmation that is useful to the blind. The serial-interface, 2 K-byte x 8-bit ROM (!C4) stores programmed sequences of instructions that are executed by the speech-processor chip IC2-manufactured by the General...

The proposed circuit is of a sequential LED light driver, especially designed to suit the application of a multipurpose car tail light indicator. The circuit is integrated to the brake switch and works as a brake light, it's also ...
The brake light circuit is pretty straightforward. Just the brake pedal switch that operates all three lights directly. The left and right brake lights share the same ground with the side markers, turn signals and back-up lights.
Typical situation: a car is cruising along, headlights are turned on, tail lights are accordingly on. When the car comes to a stop at a red light, the tail lights will go dark... usually the third brake light will come on, but often all rear lights are dark. They come back on when the brake is re...
