Category: Inside Circuits Views: 480 Rank: 10 This circuit switch slowly on and off the internal lights in a car. The delaying time can be adjusted changing the values of the 10k, 4M7 resistors and capacitor.  The BUZ74 can handle voltages of 500V, but you can use any power Mosfet transistor that can handle more than 50V. Datasheet file1: Click here to download 1N4148.pdf datasheet.

Related circuits DTL-TTL controlled buffered analog switch This analog switch uses the 2N4860 JFET for its 25 ohm ron and low leakage. The LM102 serves as a voltage buffer. This circuit can be adapted to a dual trace oscilloscope chopper When activated, the transmitter sends out a 49.890-MHz, AM rf carrier. The.receiver detects, amplifies, and decodes the rf signal, which, in turn, activates a piezo buzzer. The receiver is small enough to carry in a pocket or sit on your workbench. Electronic balanced input microphone amplifier It is possible to simulate the balanced performance of a transformer electronically with a different amplifier. By adjusting the presets, the resistor ratio can be balanced so that the best CMRR is obtained. It is possible to get a better CMRR than from a transformer Mosfet Mixer-Oscillator Circuit For Am Receivers Circuit This circuit is an improved front end for upgrading a transistor AM receiver. This front end is useful Useful for checking diodes, transistors, triacs, SCRs, resistors, and LEDs, this curve tracer should prove useful in the experimenter`s lab. It displays the volt-ampere characteristic of a two-ter-minal device on an oscilloscope. This is a simple block diagram of the EZ-Curve. Useful for troubleshooting audio, video, and lower frequency RF amplifiers, Current sensing in supply rails This capability has wide application in battery and solar-powered systems. If the ground-referred voltage output is unloaded by an amplifier, the shunt can operate with very little voltage drop across it, minimizing losses. The metal locator uses a one-transistor oscillator and an AM radio to detect metal. Transistor Q1 is a pnp transistor that is connected to an oscillator. Resistor R1 provides the correct base bias and capacitors C3 and 04 and the search coil determine the frequency of oscillation. Capacitors C3...

Nice and simple circuit!
It's possible to increase the fade in time?
Thanks
